Hi,

Looks like there is a el-service file somewhere on your classpath containing 'com.sun.el.ExpressionFactoryImpl' as expressionFactory provider, when this class is not available.

Try locating the file $java.home/lib/el.properties (or /META-INF/services/javax.el.ExpressionFactory somewhere on your classpath). Can you also double-check if the el-api.jar is present in your tomcat/lib folder?

Because there is an error trying to instantiate the el-provider, we don't fall trough to using JUEL-el as default and engine initialization fails.

Thanks for the suggestion.

Could not find the files and tomcat has the API in the lib.

Anyway to modify ant  to see where each class is being loaded from?

Thoughts??

Can the samples be run in eclipse directly?? Could not figure out a way to get them to run?? Junit tsetse fail in eclipse with the same error

Any suggestions?

Thank You

[frederikherema1]

Something that will work for you is the following:

1. Create a zip-archive containing one folder: META-INF/services/
In this folder, add the file named 'javax.el.ExpressionFactory', containing:
de.odysseus.el.ExpressionFactoryImpl
2. Rename the zip-archive to *.jar (eg. expression-fix.jar)

3. Add the jar to the $[distro}/lib folder (eg. /Users/fheremans/activiti/activiti-5.0.beta2/lib)

4. Alter file $[distro}/setup/build.xml, add an extra include to the fileset used in target 'deploy.activiti.engine.into.tomcat' (around line 312 somewhere), so it looks like the fragment below:

      <fileset dir="${activiti.home}/lib">
        <include name="activiti-cycle-${activiti.version}.jar"/>
        <include name="expression-fix.jar"/>
      </fileset>
This should fix it, however I'm not sure why this error occurs… In the next release these issue will be removed, since we use another approach for expression handling.

sorry tried everything including searching filesystem within jars…no luck

Thanks for all your help

The core team is running all on mac, so we test it actucally the most on os x.

Could you post the exact steps you do, starting from unzipping the Activiti zip ?

[coderinabstract]

Have wiped out local maven repo and rebuild and it works!!!

[jbarrez]

Great to hear it !
Strange that Maven would screw a jar … its supposed to check these things.
