1. What version/service pack of Weblogic?
          2. It looks like you are configured for a cluster. Is that correct?
          3. Have you followed the documentation for configuring classpaths and
          starting Weblogic?

Java.lang.ClassCastException: weblogic.webservice.core.soap.SOAPMessageImpl

Hello Gurus,
Can you please help me with following issue--
I have created a secured web service's client from netbeans 6.8.Then I made a jar file of it.Then I have integrated that jar in my ADF application's viewcontroller project .I have used the jar from backing bean of a jspx page.
If I create a main method in the bean and call the service from inside main method then everything works fine but if i remove the main method and call the service from a button click of the jspx page then i get the following error.

Hi Mike,
Support for SAAJ was added in WLS 8.1, see:
http://edocs.bea.com/wls/docs81/webserv/interceptors.html#1058444
Can you try your code on the latest release?
Thanks,
Bruce

Java.lang.NoSuchMethodError: weblogic.ejb20.internal.EntityEJBObject_Activa

We have Weblogic 8.1 SP2. The application has several entity beans. I just upgraded it from SP2 to SP3 and when I try to use these ejb's I am getting the following exception:
Root cause of ServletException.
java.lang.NoSuchMethodError: weblogic.ejb20.internal.EntityEJBObject_Activatable.preInvoke(Lweblogic/ejb20/
internal/MethodDescriptor;Lweblogic/security/service/ContextHandler;)Lweblogic/ejb20/interfaces/InvocationWrapper;
Note that these ejb's worked fine in SP2.
Now, just to test, I redeployed some of these ejb's and then these redeployed ejb's worked fine.
My question is, is it required to redeploy all ejb's to upgrade from SP2 to SP3?
Thanks.

redeploying the beans had the upgraded server recompile them which (probably), updated any internal references to methods. I don't quite understand one can run the beans that were compiled on SP2, on an upgraded SP3 server without having deployed (and therefore recompiled) them on the upgraded SP3 server.

Java.lang.ClassCastException: weblogic.jdbc.wrapper.Blob_oracle_sql_BLOB??

Hello. I'm trying to bring back a BLOB object from a PL/SQL procedure. I keep getting a class cast exception when I do it
java.lang.ClassCastException: weblogic.jdbc.wrapper.Blob_oracle_sql_BLOB cannot be cast to oracle.sql.BLOB
I get similar results with oracle.sql.BLOB or java.sql.Blob.
What I've noticed is that when I'm not using a JDBC URL with my AM to do the SQL it does not fail. It's when I change to a JDBC Datasource I get the class cast exception. Any ideas?
Thanks, Graeme.

In the connection pool uncheck the property "Wrap Data Types".
By default, data type objects for Array, Blob, Clob, NClob, Ref, SQLXML, and Struct, plus ParameterMetaData and ResultSetMetaData objects are wrapped with a WebLogic wrapper. This allows for features like debugging and connection usage to be done by the server.
The wrapping can be turned off by setting this value to false. This improves performance, in some cases significantly, and allows for the application to use the native driver objects directly.

Java.lang.NoSuchMethodError: weblogic.ejb.internal.EJBHomeImpl

Hi All,
I have recently encountered very very unusual problem which am not able to understand. If you could kindly shade some light on that it would be of great help. I have three environment where the application is being deployed. In the first two environment it works fine without any problem. But when I deployed in the third environment it behave very funny. The full stack trace of the error is bellow:
Exception in EJBTestClient: java.rmi.RemoteException: ; nested exception is:

The problem occurs when I try to call EJB from client. When I re-build the EJBS on the same environment it works fine. Am not able to understand this unusual behavior. If you could kindly help me understand the problem it would of great help. The environments are as follows.

Hi..
I guess itzz more of the service pack problems.
Jars built on the later version won't work in the previous version (service packs) of weblogic.
Try building a jar on the oldest version (service pack) u have and then try deploying it to the later version , i think it won't give u any problems.
Try it out and let me know if u face any problems

Java.lang.ClassCastException: weblogic.wsee.jaxws.spi.WLSProvider

My wlserver_10.3 throws the following 500 exception on the attempt to create an Endpoint. I'm using cxf-2.3.x which uses geronimo-jaxws_2.2_spec-1.0.jar where the the line Provider.java:43 simply calls "return (Provider) FactoryFinder.find(JAXWSPROVIDER_PROPERTY, DEFAULT_JAXWSPROVIDER);"
LINE 42 - public static Provider provider() {

It appeared the different ClassLoader's cause issues with casting itself. I appreciate any suggestion in resolving this ...

Thank you ... The ClassCastException has gone after I removed the entry but I got another exception below that also seems to do w/ using the wrong class. Please let me know if there is a configuration I should tweak for this?
Another the question I have is if removing the file $WL_HOME/server/lib/weblogic.jar!/META-INF/services/javax.xml.ws.spi.Provider (or any similar file) from weblogic.jar will affect any of wlserver_10.3 internal/built-in functionality?
Thanks,

Hi..
I guess itzz more of the service pack problems.
Jars built on the later version won't work in the previous version (service packs) of weblogic.
Try building a jar on the oldest version (service pack) u have and then try deploying it to the later version , i think it won't give u any problems.
Try it out and let me know if u face any problems

I was install j2re-1_4_05_windows_i586_i.exe and copy weblogic.jar file in true directory .I set the archive attribute of the applet tag to weblogic.jar path.
Can any body help me!
Thank a lot

Hi Famoniri,
I guess you have used weblogic specific libraries for looking up. IE does not know about this class and hence java.lang.ClassNotFoundException.
If the above is the cause of the problem, try packaging the weblogic jar files with the applet(not a good idea!) or use the standard javax.naming packages(may be a good idea!).
The problem causer is weblogic.jndi.WLInitialContextFactoryDelegate.newRootNamingNodeStub which is trying to load classes which are not prsent in its viscinity.
Let me know if this helps.
Regards,
Rajesh

If i restart the oc4j container then the application runs smooth again ... if i wait a couple of hours i get the same error again.
any ideia ?
My environment
Oracle application server 10g (9.0.4) on windows 2003 enterprise server
Best Regards

Question is which part of the heap is running out of space. It is more likely that your PermGen space is too small. PermGen is used for static variable, static and literal String values and classes as well. You can increase it with -XX:MaxPermSize=<value>. With a max heap size of 1024m a good starting value is 128m.
Unfortunately, you're running a very old Oracle AS and a very old JDK. Newer Oracle AS or Oracle Fusion Middleware can use newer JDKs, OFM 11g (WLS 11g) loves to run JDK 1.6 and with visualvm and the visualgc plugin you can see all the private parts of the JVM.

Getting javax.naming.NoInitialContextException: Cannot instantiate class: weblogic.jndi.WLInitialContextFactory. Root exception is java.lang.ClassCastException: weblogic.jndi.WLInitialContextFactory

We have an Issue in Weblogic6.1/7.0, while accessing a bean through Java Client. In the Code, i am providing the Initial Context factory and provider url to
InitialContext Constructor. Weblogic.jar WILL NOT be availabe in the classpath.We are Loading the classes through CustomClassLoader which was written by us by extending java.lang.ClassLoader.
While Constructing the InitialContext, it throws NoInitialContextException, the root exception it says ClassCastException.
With this i am attaching the code snippet:
JarAndClassFileLoader customLoader = JarAndClassFileLoader.getLoaderInstance();
customLoader.pathFileVec.addElement(new ZipFile("c:\\FDRIVE\\bea\\wlserver6.1\\lib\\weblogic.jar"));
Thread.currentThread().setContextClassLoader(customLoader);
Properties prop = new Properties();
prop.put(Context.INITIAL_CONTEXT_FACTORY, "weblogic.jndi.WLInitialContextFactory");
prop.put(Context.PROVIDER_URL,"t3://localhost:7001");
InitialContext itl = new InitialContext(prop) ---> Getting the above said NoInitialContextException..
Kindly provide the necessary solutions to overcome this.

I guess you did something wrong implementing your classloader(s).
This works with 7.0:
     ClassLoader weblogicClassLoader;
     Thread.currentThread().setContextClassLoader(
     weblogicClassLoader = new URLClassLoader(
     new URL[] { new URL("http://localhost:7001/classes/") }
     Hashtable env = new Hashtable();
env.put("java.naming.factory.initial", "weblogic.jndi.WLInitialContextFactory");
env.put("java.naming.provider.url", "t3://localhost:7001");
     InitialContext ctx = new InitialContext(env);
You may also look at these examples:

customLoader.pathFileVec.addElement(new ZipFile("c:\\FDRIVE\\bea\\wlserver6.1\\lib\\weblogic.jar"));
Thread.currentThread().setContextClassLoader(customLoader);
Properties prop = new Properties();
prop.put(Context.INITIAL_CONTEXT_FACTORY, "weblogic.jndi.WLInitialContextFactory");
prop.put(Context.PROVIDER_URL,"t3://localhost:7001");
InitialContext itl = new InitialContext(prop) ---> Getting the above said NoInitialContextException..
Kindly provide the necessary solutions to overcome this.--

Java.lang.ClassCastException: weblogic.jdbc20.rmi.SerialResultSet

You can try this as a work around :
// CLOB clob = ((OracleResultSet) rs).getCLOB (2); this causes the exception
// this is the work around (assuming thin drivers)
java.sql.Clob clobFromDB = (java.sql.Clob) rs.getObject("MYCLOBCOL");
int len = (int) clobFromDB.length();
String str = clobFromDB.getSubString (Long.parseLong("1"), len );

hi, all.

Getting java.lang.ClassCastException on JTree?

Am creating my tree something like this:
top = new DefaultMutableTreeNode("Bilag");
treeModel = new DefaultTreeModel(top);
tree = new JTree(treeModel);
MK_TreeBilag obj = new TreeBilag();
DefaultMutableTreeNode data = new DefaultMutableTreeNode(obj);
top.add(data);But when I try to get Obj out of the tree so I can call getId() method, am getting an ClassCastException? This is how I do:
DefaultMutableTreeNode treeObj = (DefaultMutableTreeNode) tree.getLastSelectedPathComponent();
Object obj = treeObj.getUserObject();
nodeIndeks = ((MK_TreeBilag) obj).getBilagId();can someone plz help me with this?

I cant tell why but after changing the code to this:
DefaultMutableTreeNode treeObj =
(DefaultMutableTreeNode)
tree.getLastSelectedPathComponent();
Object obj = treeObj.getUserObject();
MK_TreeBilag treeBilag = (MK_TreeBilag) obj;
nodeIndeks = treeBilag.getBilagId();
It worked?
Thx warnerja ...That looks functionally the same as what you had before. Something else must have changed.
