Problem with JNDI in cluster in SAP WAS SS9

Hello, dear experts.

We have the following problem:

In a clustered SAP WAS SS9 on Win 2K/Oracle/JDK 1.4.2_07, if a server in the cluster is shut down its JNDI entries are still visible by other servers' initial context lookup calls.

Piece of code to reproduce is as follows:

LookupTest.java:

package lookuptest;

import javax.naming.*;

import java.util.*;

public class LookupTest {

private static InitialContext ctx=null;

static {

final Properties props=new Properties();

props.put(Context.INITIAL_CONTEXT_FACTORY,

"com.sap.engine.services.jndi.InitialReplicatingContextFactoryImpl");

props.put("Replicate","true");

props.put("clear_cache","true");

try {

ctx=new InitialContext(props);

} catch (NamingException e) {

e.printStackTrace();

}

}

public LookupTest() {

}

public static synchronized String get(String name) throws NamingException {

return (String) ctx.lookup(name);

}

public static synchronized void put(String name, String value) throws NamingException, NameAlreadyBoundException {

ctx.bind(name,value);

}

}

// from JSP

<%

String name=null;

try {

name=LookupTest.get("test");

out.prinltn("Found!");

} catch (NamingException e) {

out.prinltn("Not Found!");

// not found

try {

LookupTest.put("test","test");

} catch (NameAlreadyBoundException e) {

}

}

%>

To reproduce:

Start up a cluster.

Run JSP from both servers in a cluster.

Shut down the SAP WAS server on the node that returned Not Found!.

Run JSP from another server - Found appears, although the originating server went down.

I would really appreciate any comments or suggestions.
