[JBoss Seam] - End a long running process from a page flow
by asachde
I have a pageflow which calls a SSB (derivative of todo example) and when I call the done method I get IllegalStateException ... cannot call Start from a long running transaction ... call @Begin(join=true) etc...
So I changed the done method (Instead of @BeginTask(taskIdParameter="taskId") @EndTask) to use the following code:
String l = (String) org.jboss.seam.Component.getRequestParameters().get("taskId");
long tid= Long.parseLong(l);
JbpmContext jbpm = JbpmConfiguration.getInstance().createJbpmContext();
try {
TaskInstance ti = jbpm.loadTaskInstance(tid);
ti.end();
} finally {
jbpm.close();
System.out.println("Maybe the process ended!!!");
}
The first time I call the method I get the following exception. The process ends but get the nasty stack trace on the page instead of following the page flow. If I hit back and create new long running processes and stop them I dont get any errors.
If I use RequestParameter("taskId") then any other method I call on the SSB throws an exception cannot set taskId on SSB!
What am I doing wrong.
See stack trace below:
21:57:40,735 INFO [STDOUT] Async-process ended!!!
21:57:40,755 INFO [STDOUT] The process definately ended!!!

[JBossCache] - Re: Eviction - forcibly?
by suppyam
Hi - I tried that, with some very simplistic settings:
| <!-- Name of the eviction policy class. -->
| <attribute name="EvictionPolicyClass">org.jboss.cache.eviction.LRUPolicy</attribute>
|
|
| <attribute name="EvictionPolicyConfig">
| <config>
| <attribute name="wakeUpIntervalSeconds">5</attribute>
| <!-- Cache wide default -->
| <region name="/_default_">
| <attribute name="maxNodes">5000</attribute>
| <attribute name="timeToLiveSeconds">1000</attribute>
| <!-- Maximum time an object is kept in cache regardless of idle time -->
| <attribute name="maxAgeSeconds">120</attribute>
| </region>
|
| <region name="/org/jboss/test/data">
| <attribute name="maxNodes">5</attribute>
| <attribute name="timeToLiveSeconds">4</attribute>
| </region>
| </config>
| </attribute>
|
But I get an error of the kind:
- read Method _evict(/Neat/CsticControl/EU) called - don't know how to handle, passing on!
Does this mean that its not evicting my data?
