Re: [lists-strutsuser] Re: [Workflow] ClassCastException with
TilesWorkflowRequestProcessor
Yes, com.livinglogic.struts.workflow.WorkflowRequestProcessor
initialises, but
com.livinglogic.struts.workflow.TilesWorkflowRequestProcessor does not.
Seems odd hey!
I'm using workflow-1.0.2
The jars that my war file's lib contains are:
struts-1.1.rc1.jar
struts-workflow-1.0.2.jar
commons-validator-1.0.jar
commons-resources.jar
commons-logging-1.0.2.jar
commons-lang-1.0.1.jar
commons-digester-1.4.1.jar
commons-beanutils-1.6.jar and commons-collections-2.1.jar are in my ear
file and loaded from there via application.xml (I'm using JBoss3)
Any ideas?
Regards,
Sean

Re: [lists-strutsuser] Re: [Workflow] ClassCastException with TilesWorkflowRequestProcessor
Posted by Matthias Bauer <Ma...@livinglogic.de>.
Please double-check, whether you have spelled the class name correcly,
because you should get this exception, if you have a typo in the class
name.
Next, please try, whether your application works without specifying a
processor class (in this case the TilesRequestProcessor should be used).
Maybe it is him who is throwing an exception.
If this does not bring you any further, please try to debug into the the
method ActionServlet.getReqeustProcessor() and find out where exactly
the exception is happening. It must be somewhere in there:
> try {
> processor = (RequestProcessor)
> RequestUtils.applicationInstance
> (config.getControllerConfig().getProcessorClass());
> processor.init(this, config);
> getServletContext().setAttribute(key, processor);
> } catch (Throwable t) {
> throw new UnavailableException
> ("Cannot initialize RequestProcessor of class " +
> config.getControllerConfig().getProcessorClass()
> + ": " + t);
> }
Pls. let me know about your findings.
