[Javassist] New message: "HotSwap fails on IBM jre/jdk?!"

by Edwin Guenthner

User development, A new message was posted in the thread "HotSwap fails on IBM jre/jdk?!": http://community.jboss.org/message/529647#529647 Author : Edwin Guenthner Profile : http://community.jboss.org/people/karma Message: -------------------------------------------------------------- Hello there, I am investigating if javassist hotswap might be used for some debugging work in my project. As IBMer I have to avoid the SUN stuff; so its IBM jre/jdk only for me. It took me a while to realize that I have all the things I need - I had to tell eclipse to use /usr/lib/j2sdk1.6-ibm/lib/tools.jar ... otherwise the the com.sun stuff was missing. OK, so I got that all together and tried to run the HotSwapper hello world example ... and ...it doesnt work. The little example ... is invoking HelloWorld print() ... then it tells me ** reload a logging version and sits there and nothing happens. Any idea? Anyone tried this with IBM jre before? And a basic question: in the HelloWorld example ... the HotSwapper object is created in the same JVM run that "executes" the class that is going to be exchanged. What I am looking for is this: a) invoke some JVM in debug mode (this thing comes up and is running and doing a ton of things) b) startup a second JVM ... and use HotSwap to exchange classes in the "a) JVM" That is possible, right? Its just that the HelloWorld example is simplyfying things? regards, eg -------------------------------------------------------------- To reply to this message visit the message page: http://community.jboss.org/message/529647#529647

Are you keeping some old data in the DB? by the way, you don't need to change the messaging-service.xml for that purpose. It only uses the attribute in messaging-jboss-beans.xml. -------------------------------------------------------------- To reply to this message visit the message page: http://community.jboss.org/message/529646#529646

[jBPM] New message: "Re: Converting a variable back"

by Jochen Mader

User development, A new message was posted in the thread "Converting a variable back": http://community.jboss.org/message/529645#529645 Author : Jochen Mader Profile : http://community.jboss.org/people/jochen_mader Message: -------------------------------------------------------------- I dug in a little deeper and found out that my variables generally don't get reverted. calling: engine.getExecutionService().getVariable(exec.getId(), "dataEntity") Just gives me a long and doesn't trigger revert on the converter. Is variable conversion a one way road? Thx, Jochen -------------------------------------------------------------- To reply to this message visit the message page: http://community.jboss.org/message/529645#529645

In terms of my suggestion I suspect it probably means it would have to wait for the proper OSGied version of the default domain to see if it is still useful or not. Thanks.

[jBPM] New message: "Re: getting name of leaving transition from decision node (jbpm 4.0)"

by Maciej Swiderski

User development, A new message was posted in the thread "getting name of leaving transition from decision node (jbpm 4.0)": http://community.jboss.org/message/529639#529639 Author : Maciej Swiderski Profile : http://community.jboss.org/people/swiderski.maciej Message: -------------------------------------------------------------- where do you want to place this method call (node.getAllLeavingTransitionName)? Afaik there is no such method available in public API. Most likely you could achieve that using internal classes but that is not recommended. And since at the end you will put the values (transition names) as process variables why not doing that directly?! From JSP page point of view it's transparent either you will use dynamic query of node's transitions or set it manually as process variable in the model. -------------------------------------------------------------- To reply to this message visit the message page: http://community.jboss.org/message/529639#529639

It is not String variable, i said field variable may be you guessed wrongly. In my jsp file i have lot of fields are there, the field type is not string ( HTMLINPUT HTMLBUTTON - MVC Standards).

[jBPM] New message: "Re: Creating tasks in a loop with JBPM 4.3"

by Maciej Swiderski

User development, A new message was posted in the thread "Creating tasks in a loop with JBPM 4.3": http://community.jboss.org/message/529632#529632 Author : Maciej Swiderski Profile : http://community.jboss.org/people/swiderski.maciej Message: -------------------------------------------------------------- ok, now we are on the same page Inthat case I don't think there is a generic way to do it. Since it isnot on model level then it does not have support from jpdl. According to dev guide loops can be achieved either by transitions or by node composition. In your case any of them is not applicable, so it seem like doing it programatically is the only way.
