    Default feeling like a newbie.. again...

    I'm trying to deploy mondrian/jpivot under jboss.
    Deploy goes fine (jpivot.war) but nothing happens (can't find any classes) until I explicitly start it.. (odd)..
    then I keep getting errors like:
    org.apache.jasper.JasperException: Error at (2, 60: No ClassLoaders found for: com.tonbeller.jpivot.mondrian.MondrianModel
    ... anyone had this kind of fun before?

    Are you just deploying the distributed jpivot.war?
    What version of JBoss?

    Default RE: feeling like a newbie.. again...

    (Jboss 3.2.1 w/tomcat 4.1.24)
    I tried with the jpivot.war.. and a modified mondrian.war
    (connection string changed in web.xml) and got the same problems..
    The inital error I get is shown below. Thinking maybe I messed something up, I deployed JUST the default mondrian.war, and I still get the same error - when initializing the application apparently since I can't even get the index.jsp to appear (( Any ideas??

    Default RE: feeling like a newbie.. again...

    From Andreas on the jpivot-devel mailing list:
    I can reproduce the problem here, but I do not have a solution. JPivot tries to instantiate a BooleanHandler via the apache commons digester. Maybe you could try another digester version? Is one included with JBoss?
    Andreas
    commons-digester is not included in JBoss.
    You could try changing the Java2ClassLoadingCompliance parameter in Tomcat. From our Jetty jboss-service.xml:






    <attribute name="Java2ClassLoadingCompliance">false</attribute>
    Also, I have been looking at JBoss 3.2.2 and it's jboss-service.xml has a parameter:
    <!-- A flag indicating if the JBoss Loader should be used. This loader
    uses a unified class loader as the class loader rather than the tomcat
    specific class loader.
    -->
    <attribute name="UseJBossWebLoader">true</attribute>
    Try setting it to false. I don't know whether this is relevant for you under your JBoss 3.2.1/Tomcat environment.
    What I find really frustrating is that I have seen this exact problem before under Jetty, and fixed it, and am now having a brain fade about what the problem was!

    nope... none of these are valid under 3.2.1 unless I tried in the wrong place.
    I tried them under the ClassLoading MBean ...
    <mbean code="org.jboss.web.WebService"
    name="jboss:service=WebService">
    I'll try a quick upgrade to 3.2.2

    yup..wrong place.
    Should use the tomcat jboss-service.xml.. I'll post any results.. (also going to try 3.2.2)

    no good.. at least in 3.2.1 - the second parameter doesnt exist, and changing the first to false makes tomcat fail to load properly..

    Default resolved.. mostly - use jboss 3.2.2

    If anyone has problems getting jpviot.war to run under jboss.. check your jboss version. it runs fine under 3.2.2, but I couldn't for the life of me get it to run under 3.2.1.. (

    Default RE: resolved.. mostly - use jboss 3.2.2

    From our combined experiences, I believe that the JBoss/Tomcat combination is the issue.
    We have had JPivot/Mondrian working fine with JBoss 3.2.1 and Jetty. We had already changed the Java2ClassLoadingCompliance parameter in the Jetty jboss-service.xml, which we needed to do for JetSpeed anyway. With this configuration, everything worked by just dropping the standard jpivot.war into the JBoss deploy directory and setting up the JDBC/ODBC datasource.
    On the other hand, I have not been able to get JBoss 3.2.2 + Tomcat to work. The problems are occurring before I get to JPivot/Mondrian.
    uramisten: did you have to change anything in the JBoss 3.2.2/Tomcat configuration to get things to work? If so, what?
    Thanks,
    Sherman
