by TejJBPM
Hi all
I have been trying the hello world example in http://www.jorambarrez.be/blog/2009/07/01/jbpm4-hello-world
I have configured and when I run the main class which just prints a hello world message..I get this exception..Can anybody guide me what could be wrong..? thanks in advance..

[jBPM Users] - [jBPM 4.2] MySQLIntegrityConstraintViolationException ending
by xalperte
This is the exception thrown by the engine when I try to __end__ a running instance using the EndProcessInstance command. The instance has one active task (Evaluate web order), and that task has a swimlane associated (Sales Representative).
It seems a problem with the swimlane relationship.
NOTE: I already have configured the dialect to "org.hibernate.dialect.MySQLInnoDBDialect".
The exception:
| com.mysql.jdbc.exceptions.jdbc4.MySQLIntegrityConstraintViolationException: Cannot delete or update a parent row: a foreign key constraint fails (`bpm4_jbpm/jbpm4_task`, CONSTRAINT `FK_TASK_SWIML` FOREIGN KEY (`SWIMLANE_`) REFERENCES `jbpm4_swimlane` (`DBID_`))

You need to start the process with the variable "buyer". This variable will maintain the userId of the user that starts the process. It will be used by the "Buyer" swimlane (assignee="${buyer}").

Can any one tell where is the issue. Is this issue with JBoss configuration or with data source file.
Thanks

[JBoss Cache Users] - Bug: Endless-loop in EvictionTimer thread when using LFUAlgo
by pb00067
Hi all, I like to notice a bug in JBoss-Cache but I don't know where is the right place to do it. Anyone can help ?
The bug consist in the fact that at a certain point BaseEvictionAlgorithm#prune method never exits his loop (see code below) anymore because of evictionQueue.getFirstNodeEntry() always returning the same value. Debugging the code we saw that the actual bug stays in method
LFUQueue#removeNodeEntry:
This method don't handles correctly the case non- existance of the node:
if ne == null, then neither removalQueue nor the evictionList is touched.
This causes evictionQueue.getFirstNodeEntry() returning always the same result.
BaseEvictionAlgorithm.java
| ...
| protected void prune() throws EvictionException
| {
| NodeEntry entry;
| while ((entry = evictionQueue.getFirstNodeEntry()) != null) --> ENDLESS-LOOP
| {
| if (this.shouldEvictNode(entry))
| {
| this.evict(entry);
| }
| else
| {
| break;
| }
| }
| }
LFUQueue.java:
| public void removeNodeEntry(NodeEntry entry)
| {
| NodeEntry ne = nodeMap.remove(entry.getFqn());
| if (ne != null)
| {
| // don't remove directly from the LinkedList otherwise we will incur a O(n) = n
| // performance penalty for every removal! In the prune method for LFU, we will iterate the LinkedList through ONCE
| // doing a single O(n) = n operation and removal. This is much preferred over running O(n) = n every single time
| // remove is called. There is also special logic in the getFirstNodeEntry that will know to check
| // the removalQueue before returning.
| this.removalQueue.add(ne);
| /* if(!evictionList.remove(ne)) {
| throw new RuntimeException("");
| } */
| this.numElements -= ne.getNumberOfElements();
| }
| }
Solution: following Else-block added in method LFUQueue#removeNodeEntry resolves the problem.
else { // ELSE BLOCK: bugfix: this prevents endless loop in BaseEvictionAlgorithm#prune method
| if(!evictionList.remove(entry))
| throw new RuntimeException("");
| this.removalQueue.add(entry);
| this.numElements -= entry.getNumberOfElements();
| }
Background:Im using JBoss-cache 3.2.1 GA as 2L-cache for a Hibernate application.
As Hibernate does not suggest LRU as algorhythm for 2L-cache, I use the LRU.
regards
G.D.
