[JBoss Messaging] - jbossall-client.jar contains javax.sql.* causing class cast

by nkhadakk

We are using jboss 4.2.1/Jboss messaging 1.3.0 , jetty and postgresql (8.x) on java 1.6. I have added all specified (from messaging documentation) dependencies. Everything on the Messaging side works fine. But unrelated code which uses PostgreSql based DB queries starts failing with a class cast exception(something about the driver not implementing javax.sql....). Turns out Jbossall-client.jar contains not only javax.jms.* but also javax.sql.* Is there a jbossjms-client.jar which only contains the jms packages ? OR am i stuck having to slice jbossall-client.jar manually ?

[Performance Tuning] - Re: High Swap Utilization, lot's of RAM free

by PeterJ

How did you go about selecting the NewSize and survivor ratios? With the initial ratio of 2, each survivor space is 1m and the eden 2m. You will fill up the 2m eden in no time (literally in milliseconds). And the 1m survivor space will be mostly empty because only a small fraction of objects survive a collection. For production, you should set Xmx and Xms to the same size (prevents the JVM form constantly requesting more memory, or freeing up memory, and from deciding if it should do either. I wonder if that has a bearing on the swap utilization you are seeing, not really sure, it could also be the heap sizes you are using). Do not set the heap to 28G like you have it. You will not be happy if you fill it up and the garbage collector collects that heap - it will take forever (1/2 hour, 1 hour, more???). A good starting point for the heap is 1200M, unless you can show that you need more memory, or can get away with less. Based on your system RAM, 1200M is nothing. If you set both Xmx and Xms to 1200M, you should set NewSize to around 300m (NewSize should be 1/3 to 1/4 of the heap size) . Do not set any survivor ratio arguments unless you have analyzed the data from PrintHeapAtGC and determined that you need to fine tune the survivor ratio. The resulting JAVA_OPS are thus: set JAVA_OPTS=%JAVA_OPTS% -Xms1200m -Xmx1200m -XX:NewSize=300m -XX:MaxNewSize=300m -XX:PermSize=256m View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4077545#4077545 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4077545

Hi Manik, "manik.surtani(a)jboss.com" wrote : | The entry is correct, and there is no reason that the NLS should null out the TM. | | Any reason why you're using a CR3 instead of the GA, BTW? I have been using CR3 because that was the version available for download, when I downloaded JBossCache. But I will upgrade and check the error again.

[JBoss jBPM] - Re: Passing values between task nodes

by harpritt

Hi estaub im using SEAM, SESSION scope is one of the contexts that you can work in and is also made available to the process definition...placing my variab in the session scope meant that it was available to the node imediatly following the descision node... as long as the session is not destroyed durring the decision im OK .... but i hate this method... and is esentially a hack..

[JBoss Messaging] - Re: JBoss Messaging / Spring JMS compatibility?

by nkhadakk

Ok i think i figured it out. Spring has a ton load of configuration options. One of the configurations allows for caching the consumer ... hence reducing the overhead of creating connections etc. | <bean id="URIlistener" class="org.springframework.jms.listener.DefaultMessageListenerContainer" lazy-init="false" > | <property name="concurrentConsumers" value="${medium.messaging.urimessaging.listener_count}" /> | <property name="connectionFactory" ref="ConnectionFactory" /> | <property name="destination" ref="ResolvedURIQueue" /> | <property name="messageListener" ref="uriEventMessageListener" /> | <property name="cacheLevel"> <util:constant static-field="org.springframework.jms.listener.DefaultMessageListenerContainer.CACHE_CONSUMER"/> | </property> | <property name="recoveryInterval" value="100000"/> | </bean> | | <bean id="uriEventMessageListener" class="org.springframework.jms.listener.adapter.MessageListenerAdapter" lazy-init="false"> | <property name="delegate"> | <ref bean="uriEventListener"/> | </property> | <property name="messageConverter"> | <null/> | </property> | </bean> | the property 'cacheLevel' being set to 'CACHE_CONSUMER' solves this 'too many open files issue' If not specified the default is 'CACHE_NONE'... and this appears to cause the error View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4077541#4077541 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4077541

[Installation, Configuration & DEPLOYMENT] - Class loading issue with Multiple EAR files

by amnigos

Hi All, We have two EAR files which basically communicates with other.We are using emf code in our application to provide webservices , so we have packaged emf jars with Both EAR files. The issue is if we invoke the webservices from first EAR then Jboss able to load required EMF classes and then if we invoke the webservices from second EAR it fails with EMF related classnotfound exception and Vice -Versa. We are not using any EAR level class isolation. Any help is highly appreciated.

[Beginners Corner] - Re: Error running JBoss AS for first time under Fedora

by PeterJ

Rina, you should start a new post, not append an unrelated problem to an existing post. Also, did you do a search on "NameNotFoundException comp not bound"? (Do not reply here, this was just a hint that the solution to your problem has already been discussed in a variety of posts, the search should help you find them.)

by creative777

Other commercial portal platforms I have worked with allow you to configure an admin account. As I have said if your going to support pre-exist directory services your going to run into problems.
