InitialContext error in JBoss 5.x.x

[leeroy]

Hi,

I have a strange error when I try to use a DatatSource with JNDI in JBoss 5.0.0.GA, 5.0.1.GA or 5.1.0.Beta1 but not with JBoss 4.2.2

with JRE 1.6

...

 at javax.naming.InitialContext.<init>(InitialContext.java:182)
 at com.MyPackage.MyClass.MyFunction(MyClass.java:xxx)

and it's nearly with JDK 1.5

...

 at javax.naming.InitialContext.<init>(InitialContext.java:182)
 at com.MyPackage.MyClass.MyFunction(MyClass.java:xxx)

In MyFunction, the error appear on

Context initCtx = new InitialContext();

I use de default serveur and I have copyed then edited mssql-ds.xml in server\default\deploy
I have Windows XP SP3.

I don't understand what can be my mistake because the error seem be in JBoss source.

This looks like a classic classloader issue - the two classes in question were loaded by different classloaders.

Could you explain a little more about your application? Is it standalone, or a web app or an EAR? What JARs did you package with your app?

Thank you very much, you was right.

In my webapp I had a lib jndi.jar and since I deleted it, JBoss 5 start without problem.
