Problems with DataSources (NoClassDefFoundError: com/ibm/ejs/sm/beans/RepositoryOb...

I'm trying to test if my DataSource is well configured, and I'm running this program:
**** CODE BEGIN *****
<pre>import javax.naming.*;
import java.util.*;
public class DSClient {
static String url = "iiop://xxx.xxx.xxx.xxx:900";
public static Context getInitialContext() throws NamingException {
Properties p = new Properties();
p.put(Context.INITIAL_CONTEXT_FACTORY, "com.ibm.ejs.ns.jndi.CNInitialContextFactory");
p.put(Context.PROVIDER_URL, url);
return new InitialContext(p);
public static void main(String[] args) {
Context ctx = null;
javax.sql.DataSource ds = null;
java.sql.Connection conn = null;
try {
ctx = getInitialContext();
} catch (Exception e) {
System.out.println("end getInitialContext");
if (ctx != null) {
try {
ds = (javax.sql.DataSource) ctx.lookup("jdbc/OracleDS");
System.out.println("DataSource Created!");
} catch (Exception e) {
try {
conn = ds.getConnection(user, password);
System.out.println("Connection created");
System.out.println("conn = " + conn);
} catch (Exception e) {
***** CODE END *****
I'm entering the following line to the command line, under solaris:
<pre>/opt/WebSphere/AppServer/java/jre/bin/java -cp /opt/WebSphere/AppServer/lib/ejs.jar:/opt/WebSphere/AppServer/lib/ujc.jar:./imports.jar:/opt/WebSphere/AppServer/java/jre/lib/classes.zip:./Deployedjetaced_0.5b.jar:. DSClient</pre>
***** COMMAND LINE END *****
where imports.jar are some classes my EJB need to import and Deployedjetaced_0.5b.jar are my EJB deployed.
I get the following exception:

***** EXCEPTION END *****
I have one datasource called "OracleDS" and I think it's well configured. If someone finds a mistake in the code or has some code to test DataSources please tell me so.
Thank you

Looks like you need the jar file containing the com/ibm/ejs/sm/beans/RepositoryObjectImpl class in your client's classpath.

It really looks like this, but I thought it had all jar necesary files in client's classpath, which are:
do you know which jar do I need apart from the above �?
Thank you

Start with the basics. If you're running under any flavor of UNIX, make sure that the user/group your appserver is running as has read and execute permissions on all the .jar files in ./appserver/lib.

To me it looks like you are migrating to a newer version of WebSphere.
Try using the following context factory:
The exception starts during lookup, so it might be that you are getting the wrong initial context in the first place.
I agree. Here's the link: http://aspose.com/file-tools
