Hi,
We use JBoss 5.1.0.GA and java 1.6 and run in to trouble with org.jboss.resource.adapter.jdbc.vendor.OracleValidConnectionChecker.
The oracle-ds.xml contains
<!-- sql to call when connection is created -->
<new-connection-sql>select 1 from dual</new-connection-sql>
<!-- sql to call on an existing pooled connection when it is obtained from
pool - the OracleValidConnectionChecker is prefered -->
<check-valid-connection-sql>select 1 from dual</check-valid-connection-sql>
<!--valid-connection-checker-class-name>org.jboss.resource.adapter.jdbc.vendor.OracleValidConnectionChecker
</valid-connection-checker-class-name-->
If I remove the comment around OracleValidConnectionChecker I get this warning:
08:23:24,519 WARN [org.jboss.resource.adapter.jdbc.vendor.OracleValidConnectionChecker] (http-0.0.0.0-8080-1) Unexpected error in pingDatabase
java.lang.IllegalArgumentException: object is not an instance of declaring class
How can I do this correctly?
The log says warning, but is the check done and a new connection created if the check failed?
Regards
Gunnar

We are using annovention to scan for annotations which means our Class is not loaded since it just reads the bytecode. I then have a list of all the classes I want to insert two methods into(readObject/writeObject) and add the Serializable interface too(very special platform targeted at specific problem).
Soooo, now that I have the classname and it is NOT in the classloader, I would really like to load the class now without any tweaks to the command line so all the unit tests keep working without developers having to change their config for every test case. Ideally, we don't want compile time weaving since developers run the unit tests from eclipse as well.
I am assuming, I could setup a classloader and that hopefully jbossAOP already has a classloader I can just wire in and maybe feed this special list of classes into that classloader as I discover them???
thanks for any help/pointers to more docs on this.
Dean

Hello,
I'm currently working on getting a service that is implemented using jax-ws 2.2.3 and Spring migrated from JBoss 4 to JBoss 6 and I'm having issues with the service conflicting with the JBoss CXF deployer that comes with JBoss 6. Currently when my application tries to instantiate the service I get the following exception.
java.util.ServiceConfigurationError: javax.xml.ws.spi.Provider: Provider org.jboss.wsf.stack.cxf.client.ProviderImpl could not be instantiated: java.lang.ClassCastException

I tried override which provider to use by specifying it in META-INF/services/javax.xml.ws.spi.Provider but that didn't do any good. I'm still new to CXF and JAX-WS so any help/info would be appreciated.
Thanks

[JBoss Messaging] - JMS client unable to receive messages from server

Hi,
I'm using JBoss 5.1.0.GA. There are 2 instances. One instance has ESB and some web services running. ESB has JMS listeners configured and triggers the web services. This setup works when I use a standalone Java JMS client to send request message and receive the reponse from reply queue.
Now, I moved the same standalone client code to a web application, again running on a different JBoss 5.1.0 GA instance. The message is sent successfully from client application. On server side, ESB picks it up, calls the web service and sends the reply JMS message back.
But the client application is not able to process the reply message. Immediately after "TextMessage message = (TextMessage) receiver.receive()", following exception is thrown:
16:15:56,125 ERROR [ServerInvoker] Error executing server oneway invocation request: InvocationRequest[16a6469, CALLBACK, InternalInvocation[1e63688]] org.jboss.remoting.callback.HandleCallbackException: Unknow callback type: InvocationRequest[10af156, ClientDelivery[JBossMessage[21391428092411916]:PERSISTENT]] at org.jboss.jms.client.remoting.CallbackManager.handleCallback(CallbackManager.java:125) at org.jboss.remoting.ServerInvoker.handleInternalInvocation(ServerInvoker.java:1628) at org.jboss.remoting.transport.bisocket.BisocketServerInvoker.handleInternalInvocation(BisocketServerInvoker.java:863) at org.jboss.remoting.ServerInvoker.invoke(ServerInvoker.java:878) at org.jboss.remoting.ServerInvoker$1.run(ServerInvoker.java:2026) at org.jboss.jms.server.remoting.DirectThreadPool.run(DirectThreadPool.java:63) at org.jboss.remoting.ServerInvoker.handleOnewayInvocation(ServerInvoker.java:2037) at org.jboss.remoting.ServerInvoker.invoke(ServerInvoker.java:861) at org.jboss.remoting.transport.socket.ServerThread.completeInvocation(ServerThread.java:744) at org.jboss.remoting.transport.socket.ServerThread.processInvocation(ServerThread.java:697) at org.jboss.remoting.transport.socket.ServerThread.dorun(ServerThread.java:524) at org.jboss.remoting.transport.socket.ServerThread.run(ServerThread.java:232)
I read in this forum that such issue happens when different versions of JBoss are used; but I have both the client and server applications on 5.1.0.GA.
Please let me know if there are any potential classpath or version issues I should look out for.
Thanks
Vijay
