<content:encoded><![CDATA[ <p>First the god news : it works <img  border="0" src="http://www.imixs.com/websites/blogs/ralphsoika.nsf/dx/../plugins/emotions/images/smiley-laughing.gif" />!</p><p>The main information how to setup an LDAP Realm for your WebApplication on Glassfish is from <a href="http://weblogs.java.net/blog/tchangu/" /><a href="http://weblogs.java.net/blog/tchangu/archive/2007/01/ldap_security_r.html " target="_self">Krishnan Viswanath's Blog</a><br /></p><p> </p><p>For a basic configuration it is necessary that your Domino LDAP Schema supports the attribute "uid" which mapps to the shortName. I think in all current Domino releases since 6.0 this attriubte is supported per default in the LDAP Schema. You can check this with a <a href="http://www-unix.mcs.anl.gov/~gawor/ldap/" target="_self">ldap browser</a><br /></p><p>So to configure an LDAP Realm in Glassfisch using a Domino LDAP Server set the Directory param to your domino server:<br /></p><p><strong>Directory:</strong> ldap://www.imixs.com:389</p><p>Next set the Base DN to your Organisation Unit</p><p><strong>Base DN:</strong> O=MYCOMPANY &nbsp;</p><p>&nbsp;Now the authentication works ! - But... there is a problem. You can not authenticate against Groups - which is realy necessary in a JEE App.</p><p>The reason is that domino organizes groups in the root of the ldap tree. And glassfisch configuration allows not to configure an empty Base DN or group-base-dn. </p><p>So the solution I used was to name all my Access Groups for Glassfisch : GroupName/GROUP/MYCOMPANY. So the BaseDN for Groups become "OU=GROUP,O=MYCOMPANY"</p><p>So finaly I added only this two additional parameters in my LDAP Realm Configuration:</p><p><strong>group-base-dn:</strong> OU=GROUP,O=MYCOMPANY</p><p><strong>group-search-filter:</strong> member=%d&nbsp;</p><p>The last parameter "group-search-filter" is also very significant as per default the member entries are expected in uniquemember but in Domino the corresponding field is "member". And don't forget the "%d" which takes me a long time....<br /></p> ]]></content:encoded>

<content:encoded><![CDATA[ <p>Warum ist Windows eigentlich ein so schlechtes Betriebssystem?</p><p>Ich denke, dass es eigentlich nur mit der Masse an Leuten zu tun hat die dieses Betriebssystem benutzen. Wen man Sotware schreibt macht man das in der Regel weil man Spass daran hat. Das ist bei Microsoft im Grunde nicht anders. Wen eine Software jedoch von sehr vielen Menschen verwendet wird, mu&szlig; man anfangen diese Software an die individuellen Bed&uuml;rfnisse dieser Menschen anzupassen. Der Spass beleibt dabei auf der Strecke. Windows wurde irgenwan von extrem vielen Menschen verwendet. Dadurch entstand das Problem das man heute warnimmt. Die Software "Windows" ist relativ stark verfrickelt.&nbsp; Soll heissen es wurden &uuml;ber die Jahre immer merhr Bed&uuml;rfnisse f&uuml;r Nutzer implementiert die vermutlich gar keinen Sinn gemacht haben. Die Nuter, f&uuml;r die diese Dinge letztendlich programmiert wurden schimpfen warscheinlich am lautersten &uuml;ber Windows. Aber letzendlich ist es der nat&uuml;rliche werdegang von Software die einfach f&uuml;r zu viele Menschen programmiert wurde. Das ist mit Software die man heute f&uuml;r die Raumstation programmiert vermutlich ganz anders. Diese wird f&uuml;r eine Hand voll Leuten geschrieben und funktioniert vermutlich perfekt. </p><p>Es stellt sich mir die Frage wie das jetzt eigentlich mit Linux ist. Linux funktioniert so gut weil es im Grunde f&uuml;r wenige Leute geschrieben wurde. Es wurde auch nie R&uuml;cksicht auf einzelne Nutzer genommen die das ganze System massgeblich beinflusst h&auml;tten. Aber was passiert jetzt mit Linux. Kann es sein das - nun wo Linux schon von sehr vielen Leuten verwendet wird - es jetzt beginnt ein schlechtes Betriebssystem zu werden?</p><p>hm... hoffentlich passiert das nicht....!&nbsp;</p> ]]></content:encoded>

<content:encoded><![CDATA[ <p>Hi,</p><p>today I tried to install Domino 8.0 on Ubuntu. I followed this way:</p><p>first download the isntaller tar file. unpack it with <br />>tar -xvf c13njen.tar<br /><br />next I followed the install introductions at:<br /><a href="http://coort.wordpress.com/2008/01/16/how-to-domino-8-on-ubuntu-704-virtual-machine/" target="_self">http://coort.wordpress.com/</a><br /><br />they are realy helpfull.<br />I am not sure if it is necessary to enable the root user. Maybe this will be an issue for Debian Server. But I am not sure - I try this later on Debian 4.0.</p><p>Also it seems ok to use an Java JRE 1.5.0_13 or higher.</p><p>Run the installer as sudo and console mode<br /></p><p>>sudo ./install -console<br />At the end of the installation wizzard choose "remote setup" to setup your server remotly.</p><p>After installation has fineshed the server will automatical be started in a remote mode. So now you can setup the server. </p><p>A god discription about that steps I found here:<br /><a href="http://www-12.lotus.com/ldd/doc/domino_notes/Rnext/help6_admin.nsf/f4b82fbb75e942a6852566ac0037f284/4b50b1100495666b85256c1d003906fb?OpenDocument" target="_self">http://www-12.lotus.com/ldd/doc/domino_notes/Rnext/help6_admin.nsf</a><br /></p><p><br />You need not to start the server as this was done by the installer.<br />So copy the java libs to your client:<br /></p><ul><li> From a Windows client, copy the remote setup files CFGDOMSERVER.JAR, JHALL.JAR, and REMOTESETUP.CMD from the server to the directory you created on the client system. These files are in C:\Domino program directory on the server.</li><li>From a UNIX workstation, copy the remote setup files CFGDOMSERVER.JAR, JHALL.JAR, and REMOTESETUP from the server to the directory you created on the workstation. These files are in /Domino program directory/lotus/notes/latest/ibmpow/ on an AIX server, /Domino program directory/lotus/notes/latest/linux/ on a Linux server, and /Domino program directory/lotus/notes/latest/sunspa/ on a Solaris server.</li></ul><p>After that you can start a cool java setup client </p><p><br /></p><ul><li>On a Windows client, enter remotesetup.cmd <br /></li><li>On a UNIX workstation, enter remotesetup</li></ul><p>Follow the setup wizzard - and finish installation.<br /> </p> ]]></content:encoded>

<content:encoded><![CDATA[ <p>Ich m&ouml;chte heute kurz vom ersten Tag der <a target="_self" href="http://jax.de/">W-Jax in M&uuml;nchen </a>und die die Eindr&uuml;cke die ich dabei erhalten habe berichten.<br /></p><p><strong>Er&ouml;ffnungsrede:</strong></p><p>Die Er&ouml;ffnungsrede hielt wie stehts Sebastian Meyen. Neben den &uuml;blichen  Entwicklungszahlen der Jax und W-Jax brachte er zum Ausrdurck das er - was ich sehr bemerkenswert fand - den Mytos des "Open Source vs. Kommerzielle Software" brechen will. Sein Statement in diesem Kontext "Open Source = kommerziel". Ich kann das nur begr&uuml;ssen da ich selbst im Augenblick Diskussionen in diesem Zusammenhang f&uuml;hre.</p><p><strong>Keynote  - Dynamische Sprachen f&uuml;r die JVM von Dierk K&ouml;nig</strong></p><p>Absolut beindruckend! In einer fabelhaften Pr&auml;sentation zeigte Dierk K&ouml;nig warum und wie man Dynamische Sprachen einsetzen kann. Die Livedemo war wirklich beindruckend und hat selbst mich als eingefleischten Java Programmierer &uuml;berzeugt! Man mu&szlig; sich wirklich mehr mit diesen dynamischen Sprachen auseinander setzen. Die machen manchmal wirklich Sinn!<br /></p><p><strong>Session - MDSD in der Praxis: Grafische DSL Editoren im Eclipse GMF</strong></p><p>Ich habe nicht wirklich verstanden &uuml;ber was die zwei Vortragenden eigentlich geredet haben bzw. was Sie mir vermitteln wollten. Im Anschlu&szlig; an die Session konnte ich jedoch in einem pers&ouml;nlichen Gespr&auml;ch erfahren das GMF keine Abl&ouml;sung von GEF oder EMF ist. Und damit der Imixs Workflow Modeler, welcher ja ausschlie&szlig;lich auf GEF basiert, absolut state of the art ist. Damit war dann doch auch diese Session f&uuml;r mich sehr informativ ;-)</p><p><strong>Session - Ruby on Rails - Eine kurze Einf&uuml;hrung f&uuml;r Java Entwicklung</strong></p><p>Diese Session habe ich mir eingentlich nur wegen der Keynote reingezogen. Nochmals konnte ich sehen das Dynamische Sprachen sehr cool sind. Auch wenn mich Ruby on Rails dann doch nicht wirklich &uuml;berzeugen konnte. Es scheint nicht vorgesehen zu sein einen Service Orientierten Ansatz wie den von Imixs damit weiter zu implementieren.</p><p><strong>Keynote OSGI -  The Future of Java</strong> </p><p>In der zweiten Keynote hat Peter Kriens (!) das Potential von OSGI pr&auml;sentiert. Das war nicht ganz so anschaulich wie die erste Keynote aber dennoch sehr interessant. Es ist in der Tat nicht auszuschlie&szlig;en das OSGI DAS(!) Basisframework f&uuml;r moderne Java Architekturen wird. Ja - auch den Imixs Workflow k&ouml;nnte man stark oder auch weniger stark auf diesen Framework portieren....?</p><p><strong>Session - Best Practices for OSGI</strong></p><p>Klar musste ich mir nach der Keynote gleich noch die Session von Peter Kriens reinziehen. OSGI = richtig cool. Und - ach ja - Imixs hat ja bereits auf SourceForge einige OSGI Bundles ver&ouml;ffentlicht. Wir sollten &uuml;berlegen dies weiter auszubauen und mehr solcher Bundles zu ver&ouml;ffentlichen. Schlie&szlig;lich basieren die neuesten App-Server wie BEA und Websphere auf OSGI!!!</p><p><strong>Session - JAX-RS - the Java API for RESTful Web Services</strong></p><p>Diese Session von Stevan Tilkov  war wirklich sehr gut! Ich glaube auch das wir alle viel mehr &uuml;ber das Grundparadigma von HTTP und der Kommuniktaion &uuml;ber WebBrowser nachdenken sollten. Vieles was wir heute mit WebServices l&ouml;sen kann man im Grunde stark vereinfachen. Und sollte es bei Softwareentwicklung eigentlich nicht immer darum gehen? Mit REST kann man die Abbildung eines Gesch&auml;ftsobjektes extrem vereinfachen. Ohne irgendetwas neu erfinden zu m&uuml;ssen. Das ist einfach nur seher beindruckend. Da wir heute wissen wie schwer es war den Imixs Workflow als Web Service abzubilden mu&szlig; man die Fragen nach dem Warum? ersthaft stellen. Ja nach dieser Session ist mir klar geworden: der Imixs Workflow mu&szlig; RESTfull werden...</p><p><strong>Verpflegung und Ball-Room Veranstaltung</strong> </p><p>Die Verpflegung ist absolut super! Gar kein Vergleich zu der Kartoffelsuppe die eine
m in Wiesbaden auf der JAX serviert wird. Und am Abend gibt es Bier - und das nicht aus Schnapp sgl&auml;sern auf die man ne viertelstunde warten mu&szlig;...</p><p>Es gab dann so gegen 20:00 Uhr im Ball-Room eine Round-Table Veranstaltung. Dabei konnte man an gro&szlig;en Tischen zu bestimmten Themen mit Gleichgesinnten Diskutieren. Das fand ich sehr gut und konnte zu den Thmen OSGI, EJB und REST wertfolle weitere  Anregungen sameln</p><p><strong>Fazit </strong></p><p>W-JAX erster Tag = Super ! </p><p>mal sehen was morgen kommt... </p><p> </p> ]]></content:encoded>

<content:encoded><![CDATA[ <p>Since Notes 8 runns on Linux (also on Ubuntu 7.10) I changed form Windows XP OS to Linux Ubuntu OS. As no Notes Designer is included yet in the Notes 8 client for Linux I use "Wine" to runn Notes 7.0 Designer in my linux. Wine allows you to run many Windows programs on Linux. I added wine using the Ubuntu universe software channel. After that I run the comand</p><pre><em> >winecfg </em></pre><p>to create a  ~/.wine directory in my home directory. In that directory I copy  my existing Notes 7.0 Installation running on a Windows XP partition. I also copy the Data Directory into the Notes pogramm directoy.  So I have the following directory structure:</p><p><em>/home/myaccount/.wine/drive_c/Programme/Lotus/Notes_7.0/ </em><br /></p><p>for Notes and  </p><p><em>/home/myaccount/.wine/drive_c/Programme/Lotus/Notes_7.0/data</em></p><p>for Notes Data. Next I copy the DLLs  mfc42.dll, mfc42u.dll, msvcrt.dll and msvcp60.dll into the directory<br /> </p><p><em>/home/myaccount/.wine/drive_c/windows/system32/</em></p><p>Thast all. I can now start and runn Notes 7.0 in Ubuntu with the following command</p><p><em>> wine "c:\Programme\Lotus\Notes_7.0\designer.exe"</em></p><p> </p> ]]></content:encoded>

<content:encoded><![CDATA[ <p>&nbsp;</p><p>As I played around with security in my JEE Application deployed on my Glassfish server I found something concerning security.</p><p>If you install a Glassfish Application server the embedded derby database is per default not secured and can be accessed by everyone without authentification. If your application uses entity ejbs which store there data into a derby database this is not very securely. So you maybe whant to close this security lack.</p><p>To use the build in security authentification which comes with derby follow this steps:</p><ol><li>create a derby property file <br />named "derby.properties" in&nbsp;&nbsp; ../glassfish/databases/ <br />This file dose not exist per default!<br /></li><li>add the following content to this file:<br />derby.connection.requireAuthentication=true<br />derby.authentication.provider=BUILTIN<br />derby.user.APP=yourpassword<br />derby.user.someusername=yourpassword</li><li>restart your database</li><li>reconfigure your jdbc-datapools and add one of your username/password combinations defind in your derby.property file<br /></li></ol><p>&nbsp;</p><p>Now ervery connection need to be authenticated.<br /><br /></p> ]]></content:encoded>

<content:encoded><![CDATA[ <p>After I installed IBM Websphere Integration Developer on Linux Ubuntu it makes no fun to work with WID because it often hangs my hole system with 100% CPU.<br />After that I read the manual.... ;-)<br />ok - working with Websphere Integration Developer on Linux Ubuntu will work well after your change the ulimits of your current user.<br />It is recommended that you raise the number of file handles available above the default limit of 1024 file handles per process.<br />Otherwise the WID will not work correctly because WebSphere Integration Developer requires a substantial number of files to run. (This was what I learned after I read the manual).</p><p>Now I will explain how to change the file settings on Ubuntu Feisty fawn.<br />On Ubuntu the default limit is normaly set to 1024 file handles per process to be exceeded. This will result in a failure of the WID and possibly the loss of your workspace.<br />You can check the ulimit with the command:<br /><br />>ulimit -a<br />....<br />core file size&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (blocks, -c) 0<br />data seg size&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (kbytes, -d) unlimited<br />scheduling priority&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (-e) 20<br />file size&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (blocks, -f) unlimited<br />pending signals&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (-i) unlimited<br />max locked memory&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (kbytes, -l) unlimited<br />max memory size&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (kbytes, -m) unlimited<br />open files&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (-n) 1024<br />pipe size&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (512 bytes, -p) 8<br />POSIX message queues&nbsp;&nbsp;&nbsp;&nbsp; (bytes, -q) unlimited<br />real-time priority&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (-r) 0<br />stack size&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (kbytes, -s) 8192<br />cpu time&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (seconds, -t) unlimited<br />max user processes&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (-u) unlimited<br />virtual memory&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (kbytes, -v) unlimited<br />file locks&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (-x) unlimited<br /><br />so you will see the "open files" are restricted to 1024.<br /><br />I changed this value by editing the file /etc/security/limits.conf<br /><br />Please notice the hint from IBM: Failure to follow this instructions properly could result in a machine that won't boot properly. <br />So be very carefull changing this setting.<br /><br />Ok - well you need to add only one line at the end of the limits.conf file<br /><br />myuser&nbsp;&nbsp; &nbsp;hard&nbsp;&nbsp; &nbsp;nofile&nbsp;&nbsp; &nbsp;4096<br /><br />this will change the max number of opend files to 4096 for the user "myuser" (you should replace the name to your current username)<br /><br />Notice: the maximum number of files can not be higher then value defined in /proc/sys/fs/file-max<br /><br />normaly the value is set to 205256<br /><br /></p> ]]></content:encoded>

<content:encoded><![CDATA[ <p>After I build some WebServices based on EJB 3.0 Session Beans and deployed on Glassfish I found out someting which is not obviously.</p><p>If you follow a "Contract-First" approach you can define a wsdl file in the /META-INF/wsdl directory and then use the following WebService Annotation:</p><p> </p><pre>@Stateless<br />@WebService(<br />name = "RechnerImplemenationService", <br />targetNamespace = "http://ejb.jee.workflow.imixs.org/", <br />serviceName = "RechnerImplemenationService", <br />portName = "RechnerImplemenationPort", <br />wsdlLocation = "rechner.wsdl")<br />public class RechnerImplemenation implements Rechner {</pre><p> </p><p>So this WebService will work properly. But if you try to use the Eclipse WebService Explorer Tool you will recognize that your webservice method will not receife the params correctly. After a while I found out that it is importend that if you use a wsdl file as your web service definiton in conjunction with the @WebService annotation it is recomended to use also the @WebParam Annotation inside your methods!</p><p>So for example a method should look like this:</p><p>    public int add( @WebParam(name = "a", mode = Mode.IN) int a, @WebParam(name = "b", mode = Mode.IN)<br />    int b) {<br />        return a + b;<br />    } <br /></p><p> </p><p> where "a" and "b" must be declared as the corresponding message part names in your wsdl file. Otherwise the Implementation of your session ejb is not able to receife the params properly.</p><p>So the "@WebParam" annotation is absolutly neccesary for webservice implementations when using a predefined wsdl file. </p><p> </p> ]]></content:encoded>
