[JBoss Seam] - Re: java.lang.out of memory error permgen space

by saeediqbal1

I'm glad I shared this information with you guys. Is it safe to use JRockit with Seam? Thanks. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4018604#4018604 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4018604

[JBoss jBPM] - Re: jpdl-3.2.Beta2: how to access variable from task form in

by avbentem

Another question: how to write the expression "true" if the following is not considered true...? <condition expression="#{true}"/> (http://java.sun.com/j2ee/1.4/docs/tutorial/doc/JSPIntro7.html#wp77280 defines the literal true) Read on for yet another problem in my quest to extend the websales sample for a demo: If I understand correctly then <decision name="Fits in mailbox"> | <transition name="Yes" to="ship item"> | <condition expression="#{false}"/> | </transition> | <transition name="No" to="Inform customer"/> | </decision> should execute the second transition, which has no condition and thus is the 'otherwise' branch. However, again I get [Decision] decision didn't select transition, taking default Transition(Yes) But... I get the very same message using <condition expression="#{true}"/> ...so the above might just be caused by my trouble with decisions in the workflow. If not, then maybe I'll investigate the cause later on, or repost this in a thread of its own. Documentation: http://docs.jboss.org/jbpm/v3/userguide/jpdl.html#condition.element states anonymous wrote : The contents of the condition element is a jPDL expression that should evaluate to a boolean. A decision takes the first transition (as ordered in the processdefinition.xml) for which the expression resolves to true. If none of the conditions resolve to true, the default leaving transition (== the first one) will be taken. Another section of the same page at http://docs.jboss.org/jbpm/v3/userguide/jpdl.html#decision.element claims anonymous wrote : The leaving transitions of a decision can be extended with a condition. The decision will look for the first transition for which the condition evaluates to true. A transition without a condition is considered to evaluate to true (to model the 'otherwise' branch). Arjan.

[JBoss Seam] - Re: java.lang.out of memory error permgen space

by quilleashm

There are quite a few things that are non-bug related that can cause eventual OOM with permgen on a web container redeployment. See more info here... http://opensource.atlassian.com/confluence/spring/pages/viewpage.action?p... I suspect the one that will most likely bite Seam users is the DriverManager "leak". I don't know what, if any, app servers handle these cases for you. Having said all that there is a bug in the Sun Server JVM that causes the permgen size to be larger than it should be but it doesn't leak over time. See: http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=4957990 There was a ClassLoader leak bug once upon a time but this have been fixed and backported to 1.4 and 1.5 http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=5033614 View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4018592#4018592 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4018592

[JBoss Seam] - Re: Factory and injection in EntityHome

by lightbulb432

Stepping through my debugger, the problem seems to be that ListDataModel's setRowIndex(int) is being called with a value of 0 upon first access... is there something I can do in my EntityHome to prevent this from happening, or is it a "bug"? (Meaning why is setRowIndex being called when nothing has been selected?) Anyways, once I've sorted it out I think it'll work. saeediqbal1, this is not seam-gen. I'm trying a slightly different but valid way of deleting entities from a list. I don't have anything special in my serializable class, if by that you mean entity (you can't inject into entities, using @In) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4018588#4018588 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4018588

[JBoss Seam] - Re: java.lang.out of memory error permgen space

by petemuir

Yup, I find jrockit avoids all the permgen stuff and decreases my JBoss AS start time to about 3/5ths. Apparently Java 6 also improves performance.

by chuckadams

This is a longstanding JVM bug. Increasing permgen space delays the inevitable a little bit, but switching to JRockit fixed it completely.

JBoss exposes the ThreadPool as a MBean.
