activiti 5.2 on weblogic and oracle

Hi,

Just spent a bit of time getting the distribution to run on WLS and Oracle. Here is what i did to get things working

  • configure the standard 5.2 distribution to use Oracle, using the instructions as provided in the user manual (adding jdbc driver etc). Ensure that everything still works first before continuing.

  • create a new vanilla weblogic domain using WLS 10.3 or higher. 9.2 won't work because for some reason Activiti requires a servlet 2.5 compatible container.

  • copy the war files from apps\apache-tomcat-6.0.29\webapps\ to the autodeploy directory in the domain

  • adapt surf.xml and change <endpoint-url> to the new host and port locations for each webapp

  • because of classloader issues with org.mozilla classes, you need to deploy each war as an EAR. Basically wrap each webapp in another directory and add in META-INF an application.xml like this

    • <?xml version="1.0" encoding="UTF-8"?>
    <application xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="5">
      <module>
        <web>
          <web-uri>cycle-5.2.war</web-uri>
          <context-root>/activiti-cycle</context-root>
        </web>
      </module>
    </application>
    ‍‍‍‍‍‍‍‍‍‍‍
    and also a weblogic-application.xml like this

    <weblogic-application xmlns="http://xmlns.oracle.com/weblogic/weblogic-application" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
      xsi:schemaLocation="http://xmlns.oracle.com/weblogic/weblogic-application
    http://xmlns.oracle.com/weblogic/weblogic-application/1.0/weblogic-application.xsd">
      <prefer-application-packages>
        <package-name>org.mozilla.*</package-name>
      </prefer-application-packages>
    </weblogic-application>
    ‍‍‍‍‍‍‍‍‍

  • lastly, you need to disable weblogic handling of basic authentication. by default it will intercept all basic auth requests and reject them unless the domain is correctly configured for the basic auth. This doesn't make sense for activiti because it needs to handle the auth itself. So edit config.xml and add this just before the closing tag </security-configuration>

    •   <enforce-valid-basic-auth-credentials>false</enforce-valid-basic-auth-credentials>
    ‍‍‍
That's pretty much it and things should work now.

The only thing that doesn't work is the modeler, upon deployment it throws a classnotfoundexception which is very strange:

I looked through the complete distribution for this class but cannot find it. Anyone have an idea what is going on ? I have found a reference to signavio.war in jboss-classloading.xml but where does signavio.war come from ?

HTH,
Jorg

Hey heymjo,

I don't use weblogic but thought I would mention Activiti Modeler is based on Signavio Process Editor.  The war file created in Activiti is called activiti-modeler.war, should be the same thing.  Might just need to change jboss-classloading.xml ??

Good luck,
Erik

well i did a search in a vanilla activit distribution, including all jar archives, and it came up empty. I am probably missing something obvious, i don't know why the tomcat version works fine even without this class. Can anyone point me to the supposed location of org.oryxeditor.server.BPMNLayouterServlet in the distribution ?

Thanks
Jorg

Have you tried to adjust webapps/activiti-modeler/WEB-INF/classes/configuration.properties?
It needs to point to an existing folder.

we switched to using the eclipse designer plugin, it seems that this is where most of the development is going.

hi,heymjo

I have successfully deployed the activiti 5.6 weblogic11g and oracle10g on. Your last question, where you can find your desired CLASS file.
http://signavio-oryx-initiative.googlecode.com/files/jbpmeditor.war

You also need to catalina-5.5.15.jar.

Good luck.
