[Beginners Corner] - Re: JBoss4.0.3SP1 | Issues with Parsing XML Schema importin

by sg283

Instead of parsing the schema with DOM/SAX, just loading it with URL worked with JBoss. But I donÃ¢ÂÂt know how and why? here is the sample code: URL schemaURL = Thread.currentThread().getContextClassLoader().getResource(WSConstants.BOOKING_SCHEMA_FILE); SchemaFactory provBookingSchemaFactory = schemaFactory.newInstance(XMLConstants.W3C_XML_SCHEMA_NS_URI); provBookingSchemaFactory.setErrorHandler(new InvalidXMLErrorHandler()); Schema provBookingSchema = provBookingSchemaFactory.newSchema(schemaURL); Validator provBookingValidator = provBookingSchema.newValidator(); provBookingValidator.validate(new DOMSource(requestDoc)); Earlier I was creating the schema instance using the DOM source:- Schema provBookingSchema = provBookingSchemaFactory.newSchema(new DOMSource(schemaDoc)); View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4211697#4211697 Reply to the post : http://www.jboss.org/index.html?module=bb&op=posting&mode=reply&p=4211697

[Remoting] - Socket invocator and long transactions

by doychin

Looks like there is some problem with long running transactions when used with socket invocation. I found that no matter what I will specify for transaction time out I get exception from server for trying to call statefull bean second time after 6 minutes. I'm sure there is no second call and that second call comes from the same thread that created the first call so it is not in my code but instead something internally in client side remoting code. >From what I see it looks like jboss remoting client code does not respect the availability of UserTransaction and it's timeout. Is there a solution for this problem or and updated version of remoting that supports user transactions? Is the only solution is now to increase the timeout for invocation? If I increase it to much isn't that a source for more problems later?

[JBoss Tools (users)] - Re: JBT Nightly Deleting project does not clean up metadata

by max.andersen＠jboss.com

It's a tricky question ;) The deployed files are not actually "derived" files, it could be you deployed to something you really wanted to stay deployed no matter if the file or project is deleted from your workspace (actually deleted project by default just mean you remove it from the workspace - not physically delete it) In any case I agree that it should be an option when removing a project or resource and we have had the feature request before but I can't remember why it was not added (at least as an option). I've pinged Rob to see if he remembers.

That's just a WARN message (which you can ignore) and is not related to what the original poster raised. View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4211692#4211692 Reply to the post : http://www.jboss.org/index.html?module=bb&op=posting&mode=reply&p=4211692

[Microcontainer] - Re: Accessing EJB's with custom annotations.

by ALRubinger

Ah, you're tackling this from the other end. ejb3-mc integration as described in the blog post is how I enabled @EJB injection into MC Beans. Here you're trying for custom annotation support on EJBs. As EJB bean impl classes are not installed as MC beans, the annotation plugin is not getting called. To complete the equation we'd need to revisit the EJB injection framework to leverage MC a bit more to do both this example, and stuff like @Inject MC beans into EJBs.

[JBoss Tools (users)] - undeploying a JAR

by niranjan8712

Hi users, I developed a simple EJB3.0 entity based applicaition and deployed it. I changed the persistence.xml file, undeployed the earlier jar from the server view, deleted the earlier jar from the project navigator, made a new jar and deployed it again on the server. I restarted the server. But I see - ObjectName: jboss.j2ee:service=EJB3,module=employee_new.jar State: FAILED Reason: java.lang.RuntimeException: javax.management.InstanceAlreadyExistsException: persistence.units:unitName=EntityService already registered. --- MBEANS THAT ARE THE ROOT CAUSE OF THE PROBLEM --- ObjectName: jboss.j2ee:service=EJB3,module=employee_new.jar State: FAILED Reason: java.lang.RuntimeException: javax.management.InstanceAlreadyExistsException: persistence.units:unitName=EntityService already registered. I also see this in the log - You have not defined a jta-data-source for a JTA enabled persistence context named: EntityService The new persistence.xml contains the correction for the JTA. But I think the earlier JARS are still on the server. When I see the jboss.j2ee in the JMX-Console, i see all the three jars, namely: module=employee.jar,service=EJB3 module=employee_new.jar,service=EJB3 module=employee_test.jar,service=EJB3 module=hello.jar,service=EJB3 where as, the employee_new.jar is the latest. Why is the server caching the jars? How do I remove the jars and deploy only the employee_new.jar? My way of removing the jar is: 1. in the server view remove the jar from the server 2. in the project navigator, delete the jar 3. select the spurce files and build a new jar 4. right click on the new jar and click 'make deployable' 5. restart the server. Please help me in removing the irrelevant jars.
