My application generates some reports to it's clients. But there's an error when generating the reports here's the exception:-

Recently I moved this application to JBOSS 4.0.5.GA . This application was running fine and there's no errors in generating reports in Tomcat 5

Thanks.

I believe there is a conflicting JAR file:

jdt-compiler-3.1.1.jar

I created a script to set the CLASSPATH before Tomcat runs:

#!/bin/bash

IREPORT_HOME=$HOME/bin/ireport
CLASSPATH=$IREPORT_HOME/platform9/modules/org-netbeans-core.jar:

for j in \
  $IREPORT_HOME/ireport/modules/ext/*.jar \
  $IREPORT_HOME/ide10/modules/ext/*.jar; do
  BASENAME=$(basename $j)

  # Append file names to the CLASSPATH, except those with Tomcat conflicts.
  if [ "$BASENAME" != "jdt-compiler-3.1.1.jar" ]; then
    CLASSPATH=$j:$CLASSPATH
  fi
done

export CLASSPATH=$CLASSPATH.

Save it as setenv.sh and place it in $CATALINA_HOME/bin . You will have to change the IREPORT_HOME variable accordingly.
