7:12 a.m.
Hi there, i am having the exception above mentioned, I would appreciate very much if
someone could help me. I have this methods:
public class GexpRequestProcessor extends TilesRequestProcessor {
public void process(HttpServletRequest request,HttpServletResponse response) throws
IOException, ServletException {
// Wrap multipart requests with a special wrapper
request = processMultipart(request);
// Identify the path component we will use to select a mapping
String path = processPath(request, response);
if (path == null) {
return;
}
if (log.isDebugEnabled()) {
log.debug("Processing a '" + request.getMethod() +
"' for path '" + path + "'");
}
// Select a Locale for the current user if requested
processLocale(request, response);
// Set the content type and no-caching headers if requested
processContent(request, response);
processNoCache(request, response);
// General purpose preprocessing hook
if (!processPreprocess(request, response)) {
return;
}
this.processCachedMessages(request, response);
// Identify the mapping for this request
ActionMapping mapping = processMapping(request, response, path);
if (mapping == null) {
return;
}
// Check for any role required to perform this action
if (!processRoles(request, response, mapping)) {
return;
}
// Process any ActionForm bean related to this request
ActionForm form = processActionForm(request, response, mapping);
processPopulate(request, response, form, mapping);
// Validate any fields of the ActionForm bean, if applicable
try {
if (!processValidate(request, response, form, mapping)) {
return;
}
} catch (InvalidCancelException e) {
ActionForward forward = processException(request, response, e, form, mapping);
processForwardConfig(request, response, forward);
return;
} catch (IOException e) {
throw e;
} catch (ServletException e) {
throw e;
}
//abrimos el contexto de jbpm.
processOpenJbpm();
// Process a forward or include specified by this mapping
if (!processForward(request, response, mapping)) {
return;
}
if (!processInclude(request, response, mapping)) {
return;
}
// Create or acquire the Action instance to process this request
Action action = processActionCreate(request, response, mapping);
if (action == null) {
return;
}
// Call the Action instance itself
ActionForward forward = processActionPerform(request, response, action, form,
mapping);
// Process the returned ActionForward instance
processForwardConfig(request, response, forward);
//cerramos el contexto de jbpm.
try{
processCloseJbpm();
}
catch(Exception ex){
ex.printStackTrace();
//ex.toString();
}
}
/**
* Abrimos el contexto de jbpm que se usara en las Actions.
*/
protected void processOpenJbpm(){
JbpmContext ctx = JbpmContext.getCurrentJbpmContext();
if( ctx == null ){
JbpmConfiguration.getInstance().createJbpmContext();
}
}
/**
* Cerramos el contexto de jbpm comprobando si aun sigue abierto. Deberia seguir siempre
abierto
* llegados a este punto.
*
*/
protected void processCloseJbpm(){
//se mira que no se haya cerrado previamente el contexto de jbpm.
if( JbpmContext.getCurrentJbpmContext() != null ){
if( JbpmContext.getCurrentJbpmContext().getSession().isOpen() ){
JbpmContext.getCurrentJbpmContext().close();
}
}
}
where processActionPerform has most my integration with struts ActionForward (I overwrite
some methods)
On the other hand, I in the hibernate.cfg file JBPM tables plus my own tables, all against
the same mySQL Schema.
Well, every now and then, in a random way, i get the following error:
