    EJB Client Problem

    rsuffling Newbie

      I am having problems getting my client application looking up a simple statefull sessionbean. My environment is:
      Windows2000
      jboss-3.0.0_tomcat-4.0.3
      jsdk1.4.0
      j2sdkee1.3.1

      The problem would appear to be which jar files to include in the class path. Does anyone have a definitive list of jar files to include in the CLASSPATH? Are jar files from j2sdkee1.3.1 required? Any help much appreciated.

      The jndi properties file contains:

      java.naming.factory.initial=org.jnp.interfaces.NamingContextFactory
      java.naming.provider.url=jnp://localhost:1099/
      java.naming.factory.url.pkgs=org.jboss.naming:org.jnp.interfaces
      # The jnp protocol socket factory class
      jnp.socketFactory=org.jnp.interfaces.TimedSocketFactory
      # The TimedSocketFactory connection timeout in milliseconds(0 == blocking)
      jnp.timeout=0
      # The TimedSocketFactory read timeout in milliseconds(0 == blocking)
      jnp.sotimeout=0

      The batch file I use is:

      @echo off
      set LCP=.
      REM Default locations of jars we depend on
      for %%i in (C:\jboss-3.0.0_tomcat-4.0.3\client\*.jar) do call lcp.bat %%i
      for %%i in (C:\jboss-3.0.0_tomcat-4.0.3\server\all\lib\*.jar) do call lcp.bat %%i
      REM for %%i in (..\client\*.jar) do call lcp.bat %%i
      REM This automatically adds system classes to CLASSPATH
      if exist C:\j2sdk1.4.0\lib\tools.jar set LCP=%LCP%;C:\j2sdk1.4.0\lib\tools.jar
      cd lib\client
      echo C:\j2sdk1.4.0\bin\java.exe -classpath "%LCP%" count.client.CountClient
      cd lib\client
      @C:\j2sdk1.4.0\bin\java.exe -classpath "%LCP%" count.client.CountClient
      cd ..\..


      The error message I get is:

          Looks like you've included everything except your
          ejb's home/remote interfaces.

          jboss\client contains all the jars for the client side.

            I think there are not a full list of jar files for the CLASSPATH because it varies from client to client. Here are the jar files needing for my client:

            - %JBOSS_INSTALL%\server\default\lib\jboss.jar
            - %JBOSS_INSTALL%\server\default\lib\jaas.jar
            - %JBOSS_INSTALL%\server\default\lib\log4j.jar
            - %JBOSS_INSTALL%\server\default\lib\jboss-j2ee.jar
            - %JBOSS_INSTALL%\server\default\lib\jnpserver.jar
            - %JBOSS_INSTALL%\client\jboss-common-client.jar
            - %JBOSS_INSTALL%\client\jbosssx-client.jar

            That's all what my client needs. I do not need any other jar files, even from from Sun j2sdkee1.3.1.

            NOTE: Instead of j2ee.jar from Sun j2sdkee1.3.1 you have to use jboss-j2ee.jar from JBoss.

            Hope it helps!
