Hi All,

When am trying to run the java code in tomcat server which tries to create the Initial context object with the following properties it is throwing an exception.


In my sample.client.T3MBeanConnector.java i have the following code.

Hashtable table = new Hashtable();
table.put(Context.SECURITY_PRINCIPAL, user);
table.put(Context.SECURITY_CREDENTIALS, password);
table.put(Context.PROVIDER_URL, url);
table.put(Context.INITIAL_CONTEXT_FACTORY,"weblogic.jndi.WLInitialContextFactory");

sop("Map obj : " + table); // This works

InitialContext context = new InitialContext(table); // It strucks & exception is thrown

sop("Context obj : " + context); //This will never get printed


It is throwing an exception given below.In order to create an initial context object I've set weblogic.jar in classpath in catalina.bat.From the stacktrace it is understandable that it has also been considered.But I dont know how to fix the below issue. From where(which jar) it is taking this SAXParserFactory is unknown still.When i try to run as a simple standalone program it works.But when tomcat is executing the same code it is not working.Strange!!!.What is wrong here?.

Hi,
Try to find out whether you have multiple XMLParser in your Tomcat Path
Since you have mentioned you dont know which Parser says that

Bye
 
I'm thinking about a new battle cry. Maybe "Not in the face! Not in the face!" Any thoughts tiny ad?
