getting exception while trying to register repository with jndi

Hi,

I have created one Web application project in NetBeans IDE.
To that lib folder i have added the jackrabbit-standalone-1.5.4.jar file.
Then i have created one java file and placed the sample code which is given
in below link.

http://www.ibm.com/developerworks/java/library/j-jcr/

by running that java file ,im able to add/retrieve contents in repository.

Now i need to view the repository nodes using JCR browser.
For that i have downloaded the WAR file jcr-explorer.war from net.
Deployed it in tomcat 6 and imported that war project inside NetBeans IDE.
now im able to launch the Login page of it.
It is asking for JNDI name,username and pwd.

so i tried registering the repository with JNDI by refering the below link

http://jackrabbit.apache.org/jcr-client-application-howto.html

To my Web application's (where sample code resides) web.xml and the java
file i have added the code snippets as given in above link.When i run that
java file.

Im getting below exception:

May 5, 2009 9:39:19 AM NewClass1 main
SEVERE: null
javax.naming.NoInitialContextException: Need to specify class name in
environment or system property, or as an applet parameter, or in an

at
org.apache.jackrabbit.core.jndi.RegistryHelper.registerRepository(RegistryHelper.java:77)
at NewClass1.main(NewClass1.java:41)

Please help me to resolve this.(i'm new to JCR ,please tell me whether im in
rite path)

Thanks in advance,

Hi,

Even after changing the code using lookup...getting same error as before.

            InitialContext ctx = new InitialContext();
            Context environment = (Context) ctx.lookup("java:comp/env");
            Repository r = (Repository)
environment.lookup("jcr/repository");
            SimpleCredentials cred = new SimpleCredentials("userid",
                                                            
"".toCharArray());

            Session session = r.login(cred, null);
            Workspace ws = session.getWorkspace();
            Node rn = session.getRootNode();

            //print the root node name

            System.out.println("Name of the
RootNode"+rn.getPrimaryNodeType().getName());

getting error like 

javax.naming.NoInitialContextException: Need to specify class name in
environment or system property, or as an applet parameter, or in an
application resource file:  java.naming.factory.initial
        at
javax.naming.spi.NamingManager.getInitialContext(NamingManager.java:645)
        at
javax.naming.InitialContext.getDefaultInitCtx(InitialContext.java:288)
        at
javax.naming.InitialContext.getURLOrDefaultInitCtx(InitialContext.java:325)
        at javax.naming.InitialContext.lookup(InitialContext.java:392)
        at NewClass1.main(NewClass1.java:53)

In web.xml also i have added the tag as given in the 

http://jackrabbit.apache.org/jcr-client-application-howto.html link

What else i need to change to access the repository via jndi.
Please help us to resolve.

Thanks.

If NewClass1 is your client, you should retrieve the repository from
JNDI there, and not register it (RegistryHelper.registerRepository()).
The lookup code is the one on
http://jackrabbit.apache.org/jcr-client-application-howto.html
