1. There is an issue with JSP parsing for certain functions https://www.ibm.com/developerworks/community/forums/html/topic?id=77777777-0000-0000-0000-000014934503. This causes a JSP compilation issue in jw/WEB-INF/jsp/console/app/processView.jsp.

Caused by: javax.el.ELException: Function 'fn:escapeXml' not found at org.apache.el.lang.ExpressionBuilder.visit(ExpressionBuilder.java:197) at org.apache.el.parser.SimpleNode.accept(SimpleNode.java:151) at org.apache.el.lang.ExpressionBuilder.prepare(ExpressionBuilder.java:155) at org.apache.el.lang.ExpressionBuilder.build(ExpressionBuilder.java:173) at org.apache.el.lang.ExpressionBuilder.createValueExpression(ExpressionBuilder.java:216) at org.apache.el.ExpressionFactoryImpl.createValueExpression(ExpressionFactoryImpl.java:67) at org.apache.jasper.runtime.PageContextImpl.proprietaryEvaluate(PageContextImpl.java:777) at com.ibm._jsp._processView._jspx_meth_c_forEach_0(_processView.java:4001) at com.ibm._jsp._processView._jspService(_processView.java:404)

In jw.war, replace that file with the updated one attached here.

2. Libraries (batik) not found when generating process images. Download the following JAR libraries and add them into jwdesigner/WEB-INF/lib

3. Deploy the updated jw and jwdesigner WARs

Installation on Glassfish 4.1

(8.5.5.7)

  1. Deploy the jw.war and jwdesigner.war files, they should work as normal.

Installation on JBoss EAP 6.4 (6.4.0)

  1. Deploy the jw.war and jwdesigner.war files, they should work as normal.

Installation on Glassfish 4.1

...

  1. GlassFish runs an older version of the Apache Felix OSGI container, so there is a class loader conflict.

    Code Block
    java.lang.LinkageError: loader constraint violation in interface itable initialization: when resolving method "org.apache.felix.framework.wiring.BundleCapabilityImpl.getResource()Lorg/osgi/resource/Resource;" 
the class loader (instance of org/glassfish/web/loader/WebappClassLoader) of the current class, org/apache/felix/framework/wiring/BundleCapabilityImpl, and the class loader (instance of java/net/URLClassLoader) for interface org/osgi/resource/Capability have different Class objects for the type tyImpl.getResource()Lorg/osgi/resource/Resource; used in the signature

     To mitigate this, we will need to downgrade the Apache Felix libraries before deploying to GlassFish.

  2. Expand (unzip) jw.war
  3. Delete the newer Apache Felix jar files from WEB-INF/lib:
    1. org.apache.felix.framework-4.6.1.jar
    2. org.apache.felix.main-4.6.1.jar
  4. Add the older Apache Felix jar files below into WEB-INF/lib:
    1. org.apache.felix.framework-4.0.3.jar
    2. org.apache.felix.main-4.0.3.jar
  5. Add a modified Apache Felix config.properties file below (which contains a new property felix.service.urlhandlers=false) into WEB-INF/classes 
    1. config.properties
  6. Repackage into an updated jw.war
  7. Deploy the updated jw.war and jwdesigner.war
