$Proxy60 - returned by JBOSS JNDI Context

[anandhakrishnank]

Hi All,

          I am facing a strange ERROR, infact it is not an error thats how
the jboss returns the object. JBOSS returns $Proxy60, when i try to
retrieve object from Context. Please find the details below.

MBEAN DEFN:
<server>
<mbean code="org.jboss.naming.ExternalContext"

name="jboss.jndi:service=ExternalContext,jndiName=external/ldap/jboss">
    <attribute name="JndiName">java:external/ldap/jboss</attribute>
    <attribute name="Properties">

java.naming.factory.initial=org.jnp.interfaces.LocalOnlyContextFactory
    </attribute>
    <attribute
name="InitialContext">javax.naming.ldap.InitialLdapContext</attribute>
    <attribute name="RemoteAccess">false</attribute>
</mbean>
</server>

The Mbean is JBOSS Class, I am testing this with JBoss standards and not
with my customClass.

[step A]Context envContext = (Context)ctx.lookup("java:");
[step B]Object ldapCtx = (Object)envContext.lookup("jndi/externalLDAP");

In step A, I could retieve the Initial Context.
But, in step B, It returns me $Proxy60 and I am unable to typecast this
object.

Here s my code again:

[1]Context ctx = new InitialContext();
[2]Context envContext = (Context)ctx.lookup("java:");
[3]Object ldapCtx = (Object)envContext.lookup("jndi/externalLDAP");
[4]System.out.println("Class name:- "+ldapCtx .getClass().getName());
[5]System.out.println("Object value:- "+ldapCtx.toString());

The output is as follows
[line 4: prints this value] Class name:- $Proxy60
[line 5: prints this value] Object value:-
javax.naming.InitialContext@b3826f

IF I type caste to InitialContext, it gives me ClassCastException.

Any suggestion, how to use this object?

Thanks,

Anand

I had come across the $proxy60, by using Context{line 3}, instead of InitialContext as given below:

/*[1]*/PrintWriter w = response.getWriter();
/*[2]*/NamingContext envCtx = (NamingContext) intialCtx.lookup("java:");
/*[3]*/Context ldapCtx = (Context) envCtx.lookup("external/ldap/jboss");
/*[4]*/InitialContext initialContext = new InitialContext(ldapCtx.getEnvironment());
/*[5]*/w.println(initialContext.toString()+"<br/>");
/*[6]*/w.println(initialContext.getEnvironment());

{line 5 prints :}
javax.naming.InitialContext@1cece51
{line 6 prints :}
{java.naming.factory.initial=org.jnp.interfaces.LocalOnlyContextFactory, java.naming.factory.url.pkgs=org.jboss.naming:org.jnp.interfaces:org.jboss.naming:org.jnp.interfaces}

I need to convert this object to LocalOnlyContextFactory, thats how I could use in my application.
Please suggest!

If try type-casting, it gives ClassCastException:
LocalOnlyContextFactory typeCtx =(LocalOnlyContextFactory)ldapctx;{ldapCtx from line:3}

Please suggest solution to get the right context to use in my application.

Thanks,

Anand

 I had attached the sample application, and had commented on JNDITest Servlet source code. Please check and revert.

Are you packaging any jar files containing org.jboss.naming.* or org.jnp.* packages in your application? If yes, then remove such jars from your application packaging.

Hi,

Thanks for your information,

I don't have any single jar in my war file, All the required class are available by default in Jboss 4.2.3 GA version.

I got some these input from others discussion.

Thanks,

Anand
