[JBoss Remoting] - big outgoing traffic on remote call

by Berik Berentayev

Berik Berentayev [https://community.jboss.org/people/berik] created the discussion "big outgoing traffic on remote call" To view the discussion, visit: https://community.jboss.org/message/754287#754287 -------------------------------------------------------------- Hi! While invoking a remote method on SLSB I have big outgoing traffic (~4KB per call). Now we have outgoing traffic 10 times bigger that incoming. I think it's strange. Here is the conent of outgoing packets captured by Wireshark while calling method that takes one parameter. Why it sends too many information?

[JBoss Remoting] - Default value of client side timeout.

To view the discussion, visit: https://community.jboss.org/message/753381#753381 -------------------------------------------------------------- Hi, I was wondering if someone knows the reason why the client side timeout value is set to 1800000 milliseconds (30 minutes). This seems to be a very long timeout default.

[jBPM] - Question about task names

by jnorris

jnorris [https://community.jboss.org/people/jnorris] created the discussion "Question about task names" To view the discussion, visit: https://community.jboss.org/message/759226#759226 -------------------------------------------------------------- Hi All, We came across a situation in jbpm5.2 where a drools:taskname value that was created when the human task form was created in the jbpm console was the same as one that was already in use in a different process. This caused the running process instance not to function correctly. Changing the drools:taskname value in the process definition file to a unique value and re-deploying fixed the issue. So my question is, can the same drools:taskname value be used in multiple process definition files? Thanks, Jim -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/759226#759226] Start a new discussion in jBPM at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&con...]

[JBoss Microcontainer] - How to re-compile a class loader

by lavot

lavot [https://community.jboss.org/people/lavot] created the discussion "How to re-compile a class loader" To view the discussion, visit: https://community.jboss.org/message/746164#746164 -------------------------------------------------------------- Hi, I'm completely new here. I've been requested to help to improve perf on a project that runs under jboss 5.1.0. We've done a jstack and most of the threads that run our code are blocked in the class loader in loadClass(). I've downloaded 2.09.GA jar of the class loader which seemed to improve a little the perf but now most of the threads are blocked in doLoad(). I've activated the traces for BaseClassLoader to try to understand which classes are loaded as after a few minutes of execution, I would have expected that all the classes would have been already loaded. And that seems to be true as far as I saw: 2012-07-03 14:21:46,429 [WorkManager(2)-3] TRACE org.jboss.classloader.spi.base.BaseClassLoader - BaseClassLoader@c9447{vfszip:/opt/ESG/absapp/jboss-5.1.0.GA/server/prime/deploy/prime-cap-sms-ejb.jar/} loadClass ...capabilities.common.adapter.CapOutgoingAdapterApi resolve=false 2012-07-03 14:21:46,431 [WorkManager(2)-3] TRACE org.jboss.classloader.spi.base.BaseClassLoader - BaseClassLoader@c9447{vfszip:/opt/ESG/absapp/jboss-5.1.0.GA/server/prime/deploy/prime-cap-sms-ejb.jar/} already loaded class interface ...capabilities.common.adapter.CapOutgoingAdapterApi{cl=BaseClassLoader@c9447{vfszip:/opt/ESG/absapp/jboss-5.1.0.GA/server/prime/deploy/prime-cap-sms-ejb.jar/} codeSource=(jar:file:/opt/ESG/absapp/jboss-5.1.0.GA/server/prime/deploy/prime-cap-sms-ejb.jar!/ <no signer certificates>)} Therefore, I don't understand why my class loader goes to doLoad() and then there gets blocked on the synchronize. So, after that long introduction, here is my point. I'd like to understand better what is done in the class loader. So, I've decided to recompile a class loader with more traces but I failed. Could someone help me ? I checked out the code: c:\Program Files (x86)\Apache-Subversion-1.7.5\bin\svn.exe" co http://anonsvn.jboss.org/repos/jbossas/projects/jboss-cl/tags/2.0.9.GA http://anonsvn.jboss.org/repos/jbossas/projects/jboss-cl/tags/2.0.9.GA 2.0.9.GA And tried to compile: mvn clean install And got what I didn't understand: [INFO] Scanning for projects...

[jBPM] - jBpm 5.2 persistence problem - Oracle - Unknown entity: org.drools.persistence.info.SessionInfo

by Samrat Roy

Samrat Roy [https://community.jboss.org/people/whizkid.samrat] created the discussion "jBpm 5.2 persistence problem - Oracle - Unknown entity: org.drools.persistence.info.SessionInfo" To view the discussion, visit: https://community.jboss.org/message/717687#717687 -------------------------------------------------------------- Hi , I am setting up jBpm 5.2 with persistence for the first time and facing a LoT of issues. I am using jpm 5.2 with Spring 3.0 and Hibernate 3.5.6 on jBoss AS 7 server. We all know that jBoss AS 7 comes with Hibernate 4 as the default hibernate , but I need to use the Hibernate 3 in my project so I installed hibernate 3 as a module in as7 and that is working as expected . I excluded Hibernate 4 with jboss-deployment-structure.xml and added org.jboss.as.jpa.hibernate:3 as a dependency in manifest.mf [refer http://badr-elhouari.blogspot.in/2011/10/how-to-use-hibernate-3-as-jpa-pr... here how I added hibernate:3 as a module in AS7] That said , I have configured the entire knowledge base and knowledge session in spring so that I dont have to write code for that - Taking tips from drools - integration module and by using drools-grid-impl jar and drools-spring jar. Drools-grid jar contains a persistence.xml which used in memory DB [h2] so I modified the xml to use oracle and hibernate 3 instead. Here is my *application context*: <bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean" p:dataSource-ref="datasource"> <property
