[Design of JBoss jBPM] - Re: org.jbpm.JbpmException: couldn't deserialize object

by tom.baeyens＠jboss.com

sorry, my bad. now that you mention it, it does ring a bell that we looked at this some time ago. let's release the hacky fix and see if it stands. "alex.guizar(a)jboss.com" wrote : Fady fixed it with a hack on VariableInstance, which goes to prove that a hack is faster than discussion ;-) indeed :-) but be very carefull with classloader hacks. very often they backfired on me and i spend lots of time afterwards fixing it in different environments.

[Design of JBoss jBPM] - Re: org.jbpm.JbpmException: couldn't deserialize object

by alex.guizar＠jboss.com

Bernd and other folks' examples in JBPM-1024 are about storing serialized objects in the variables, which is what I think is worth addressing. These objects cannot be deserialized if the class files are only present in the process archive. Now I understand what you meant by hibernate not knowing of the class, but hibernatable objects are not what JBPM-1024 is about. As Ronald points out, fixing the issue for hibernatable classes is harder. I don't know how to override hibernate's class loader except for overriding the context class loader, which will certainly open a can of worms. I committed a unit test (CustomSerializableVariableDbTest) which shows that JBPM-1024 affects 3.2.2 but not the current CVS head. Fady fixed it with a hack on VariableInstance, which goes to prove that a hack is faster than discussion ;-) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4155215#4155215 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4155215

[Design of JBoss jBPM] - Re: org.jbpm.JbpmException: couldn't deserialize object

Hi Tom, Sorry, but we started this thread indeed with just serializing objects into blobs. My use case was: Get a sample running with the web console. There I added some "business objects" to the process by an action handler. These objects were just deployed together with the process definition. When I arrived in a task form I got the exception, because the class cannot be found for deserializing (and the root cause isn't shown in the console, so it wasn't straight forward to figure out what was the problem). It wasn't a hibernate class and not the any association... With a hibernate class IT MUST be on the classpath, because it is in the hibernate mapping, no problem here I think...

[Design of JBoss jBPM] - Re: ending a process from other token than root token

by tom.baeyens＠jboss.com

quickest way is to contribute a patch in the jira issue i created. http://jira.jboss.com/jira/browse/JBPM-1184 if we have to do it, it might be postponed. Thanks for reporting it !

[Design of JBoss jBPM] - Re: org.jbpm.JbpmException: couldn't deserialize object

by tom.baeyens＠jboss.com

this topic is about "business object classes" the hibernatable user objects that are stored in the variables through as a reference mapped with hibernate's "any". it's not about serializing the object.

anonymous wrote : still hibernate will not know of the class. Why does hibernate have to know about the process classes? As I see it, hibernate only needs to provide the byte array. It is SerializableToByteArrayConverter's responsibility to read an object from the bytes. A subclass of ObjectInputStream may be required to bring the ProcessClassLoader into the equation without touching the context class loader.

[Design of Management Features on JBoss] - Re: JBAS-4156: Adding bind address to JMX console header

by jprindiv

The markup for page has changed between Branch_4_2 and trunk, so the exact same patch can't be applied to both. Nothing is functionally different, but if it matters, the trunk patch has been attached to the ticket as well.

[Design of Management Features on JBoss] - Re: JBAS-4156: Adding bind address to JMX console header

by dimitris＠jboss.org

It's ok for Branch_4_2 & trunk. For correctness you need to do: bindAddress = System.getProperty("jboss.bind.address", ""); View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4155146#4155146 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4155146

[Design of Management Features on JBoss] - JBAS-4156: Adding bind address to JMX console header

by jprindiv

JBAS-4156 suggests adding the address to which the server instance is bound to the header of the JMX console. I've attached a patch to the ticket. Anyone object to this going into Branch_4_2?
