      Hello,

       

      I am taking my baby steps in to jBPM 4.4. I going through the User Guide and setting up workspace accordingly.

      http://docs.jboss.org/jbpm/v4/userguide/html_single/

       

      I have imported the example source code that comes through standard download.

       

      When I try to run the examples , i get the below error . Pls help  ,what I am missing.

          I feel your pain.  I found a reference to your problem on http://www.coderanch.com/t/214707/JSF/java/javax-el-package.  Basically it looks like the web app your using does not support Servlet 2.5/JSP 2.1.  If you use something newer like Tomcat 6 the library should be available.  Hope this helps.

            Hi Jim,

            I got my workspace setup. I was just blindly following the notes from

            http://docs.jboss.org/jbpm/v4/userguide/html_single/ to get things started.

             

            Finally, I added the below Jars to buildpath to finally get things going.

             

            junit-3.8.1.jar

            commons-collections-3.2.1.jar

            mail-1.4.jar

            subethasmtp-wiser-1.2.jar

            el-api-6.0.20.jar

            jta.jar

            dom4j.jar

            hibernate-core.jar

            slf4j-log4j12-1.6.1.jar

            slf4j-api-1.6.1.jar

            log4j.jar

            hsqldb.jar

            javassist.jar

            antlr.jar

            antlr-runtime.jar

             

            If we are using the sl4j jars bundles along with standard jbpm download , we will end up crossing our paths with below error.

            ==============================================================

            Exception in thread "main" java.lang.IllegalAccessError: tried to access field

            org.slf4j.impl.StaticLoggerBinder.SINGLETON from class org.slf4j.LoggerFactory

               at org.slf4j.LoggerFactory.<clinit>(LoggerFactory.java:60)

            ==============================================================

            Solution is to refer to http://www.slf4j.org/faq.html

             

            Thanks .
