NoInitialContextException

Hi!
I have uploaded my jar file on weblogic server 6.1.
But when i execute my client program it gives me following
problem .
Exception in thread "main" javax.naming.NoInitialContextException: Need to speci
fy class name in environment or system property, or as an applet parameter, or i
n an application resource file: java.naming.factory.initial
at javax.naming.spi.NamingManager.getInitialContext(NamingManager.java:6
43)
at javax.naming.InitialContext.getDefaultInitCtx(InitialContext.java:246
at javax.naming.InitialContext.getURLOrDefaultInitCtx(InitialContext.jav
a:283)
at javax.naming.InitialContext.lookup(InitialContext.java:350)
at HelloClient.main(HelloClient.java:17)
So pl. tell me how to solve this.
Thanks

Assuming ur client is a standalone application...
Make sure the file weblogic.jar is present in the classpath of ur client. Also make sure u specify the name of the InitialContextFactory class while creating the InitialContext.
eg.,
Context ctx = null;
Hashtable ht = new Hashtable();
ht.put(Context.INITIAL_CONTEXT_FACTORY,"weblogic.jndi.WLInitialContextFactory");
ht.put(Context.PROVIDER_URL,"t3://machineName:port_no");
ctx = new InitialContext(ht);

Exception in thread "main" javax.naming.NoInitialContextException: Need to

Hey,
I am exploring the technique 'JMS'. I found an sample code on the Internet (https://www.redhat.gl/docs/manuals/jboss/jboss-eap-4.2/doc/Server_Configuration_Guide/JMS_Examples-A_Point_To_Point_Example.html).
But unfortunately, by running the code on my local computer, I got an NoInitialContextException (Exception in thread "main" javax.naming.NoInitialContextException: Need to ...Application resource file: java.naming.factory.initial). After searching on the Internet, I discovered I need to configure some JNDI values. But, also after passing on the variables to the class by parameter (-Djava.naming.factory.initial=com.sun.enterprise.naming.SerialInitContextFactory), I still get the same error.
What have I forgotten? Hope someone can help. Thanks!

At a guess, I would say you "Need to specify class name in environment or system property, or as an applet parameter, or in an application resource file". But I'm just guessing.

Error in EJB client program (javax.naming.NoInitialContextException)

Hi folks ,
I'm new to j2ee programming and using Netbeans 5.5 , i created a session bean program and deployed successfully in JOnAS application server but i'm not able to run the client program which invokes session bean (EJB module ).
when i run client program i'm getting the following error .

but the same program runnig perfectly when i deploy in Java System Application Server(8.2(JSAS))
I included j2ee.jar and appserv-rt jar in classpath of client program for JSAS i don't know what are the jar files (which does the same function as j2ee.ar,appserv-rt.jar ) which is to be included for JOnAS .
i'm struggling with this for the past two weeks . please tell me the solution .
Thanks in advance

Thanks for the suggestion artntek.
I located the jndi.properties file in the %J2EE_HOME%\lib\classes folder, and I copied it to the %J2EE_HOME%\bin directory, but nothing seems to have changed.
does anyone know what value should be associated with Context.INITIAL_CONTEXT_FACTORY in the properties for the InitialContext object? More specifically, what value should be used for the reference install of the 1.3 j2ee release from sun?
This error suggests to me that a class name must be specified for the initial naming context factory - but I don't know what to use.

Using JDBC Data Sources with ADFBC, NoInitialContextException

Using JDBC Data Sources with ADF Business Components, NoInitialContextException
I follow the instruction in the link below to create an ADF Swing application using datasource. I am using JDeveloper version 10.1.3.
http://www.oracle.com/technology/products/jdev/howtos/10g/usingdatasources/using_datasources.html
The ADF generated code looks like this:
JUMetaObjectManager.setErrorHandler(new JUErrorHandlerDlg());
JUMetaObjectManager mgr = JUMetaObjectManager.getJUMom();
mgr.setJClientDefFactory(null);
BindingContext ctx = new BindingContext();
ctx.put(DataControlFactory.APP_PARAM_ENV_INFO, new JUEnvInfoProvider());
ctx.setLocaleContext(new DefLocaleContext(null));
HashMap map = new HashMap(4);
map.put(DataControlFactory.APP_PARAMS_BINDING_CONTEXT, ctx);
mgr.loadCpx("datasource.view.DataBindings.cpx" , map);
final FormMain frame = new FormMain();
frame.setBindingContext(ctx);
I got this error when executing the last line: frame.setBindingContext(ctx);

If I configure the application module connection type as JDBC URL, everything works.
If the connection type is JDBC Datasource, I got the above error.
Can someone show me how to adjust the generated code by ADF to use datasource?

ADF BC has a bug. With Data Source in Application Module, application module does not connect. Use JDBC Connection URL.

Thanks, Anuj.
Indeed I did not read 18.1. Now I have.
18.1 uses Unix syntax, the Windows syntax (where I am working) would look like that shown below, where JDK location will naturally vary and the middleware home may be different:
set ORACLE_HOME=C:\Oracle\Middleware\11g_home\Oracle_SOA1
set ANT_HOME=%ORACLE_HOME%\..\modules\org.apache.ant_1.7.1
set JAVA_HOME=C:\jdk1.6.0_20
The one-off jndi properties generation will be as shown in teh manual however it would see that teh port number of the weblogic server may need to be changed as well as the weblogic password - for me it was generated as 8001 whwere my weblogic server actually runs on 7001
@REM create once off jndi proprties
cd %ORACLE_HOME%\bin
ant -f ant-b2b-util.xml b2bcreate-prop
@rem Edit the jndi.properties file to include the weblogic password and fix weblogic port number
To submit a "repaired" applicaiton message one would do:
@rem run the utility - must have absolute path to message file!
set ORACLE_HOME=C:\Oracle\Middleware\11g_home\Oracle_SOA1
set ANT_HOME=%ORACLE_HOME%\..\modules\org.apache.ant_1.7.1
set JAVA_HOME=C:\jdk1.6.0_20
%ANT_HOME%\bin\ant -f %ORACLE_HOME%\bin\ant-b2b-util.xml b2bresubmit ^

-Ddirection=OUTBOUND ^
-Dpayloadpath=C:\hl7\repair\AppMsg_Payload_2d373838303530333432393931303931.txt
It is critical to make sure the absolute path to the repaired message file is provided otherwise null pointer exceptions will be had even if the command is executed from the directory in which the messge file is located.
Another thing that will trip the beginner is the Message ID. The Message ID that is needed is that shown all over the place as MSG_ID or as b2b.messageId, which are the same. In the B2B Web Console this message ID will be shown in "application Message" tab of teh "reporting" facility, when one clicks the "details" "button" and looks at b2b.messageId property value. It is also shown as "Message Id" in teh details of teh business message. It would be nice if one could see this applicaitn message id in teh applicaiton messages report but I guess one can't have everything.
One also gets to know what the applicatin message Id is when one "downloads" the payload of the application message. The file name, which will be provided as default, will have the message id embedded - nice and easy :-) AppMsg_Payload_2d373838303530333432393931303931.txt

EJB ERR: Namingexception caught:javax.naming.NoInitialContextException

Can anyone tell me how to properly set the jndi settings?
Thanks!
Also: everything works fine when the bean is used in a jsp or servlet either directly or through an access bean.
The above code is for a remote client trying to access the bean.

It is not the JNDI settings. Check to see if you have the jar file containing the WsnInitialContextFactory available in your classpath

Naming error: javax.naming.NoInitialContextException

I get the below error message when I try to run the testing class below that. I googled the exception and read:
This exception is thrown when no initial context implementation can be created. The policy of how an initial context implementation is selected is described in the documentation of the InitialContext class.
// then I read this: http://publib.boulder.ibm.com/infocenter/adiehelp/index.jsp?topic=/com.sun.api.doc/javax/naming/NoInitialContextException.html
This exception can be thrown during any interaction with the InitialContext, not only when the InitialContext is constructed. For example, the implementation of the initial context might lazily retrieve the context only when actual methods are invoked on it.
I really dont understand what I read. Could someone please explain what my issue is and why it is occurring and how I could fix it.
Thank you in advance,
Crystal

Aleen - Thank you for your help but I just dont get what you are saying at all! I am reading through all the links and its just not clicking with me. Is it possible for you to show me a vague example of what you mean?
What do you mean by system properties/enviroment parameters? Do you mean what is in my web.xml/server.xml, like so?
public static Connection grabConnection() {
        Connection conn = null;
        try {
            Context ctx = (Context)new InitialContext().lookup("java:comp/env");
            DataSource ds = (DataSource)ctx.lookup("jdbc/connectDB");
            conn = ds.getConnection();
        } catch(SQLException e) { System.err.println("SQL error: " + e);
        } catch(NamingException n) { System.err.println("Naming error: " + n);
        return conn;
web.xml
<description>MySQL Test App</description>
<resource-ref>
      <description>DB Connection</description>
      <res-ref-name>jdbc/connectDB</res-ref-name>
      <res-type>javax.sql.DataSource</res-type>

             timestamp="true"/>

               url="jdbc:odbc:webdev"/>
</Context>I just dont understand why if I have this code in a servlet it works fine but when I try to put it in a java class it doesnt work. And I am sorry in advance, I am not trying to be a pain in the a55 to you.. and I will keep reading
Thanks - Crystal

NoInitialContextException error in Client stub tester

My bean is in the testing package. It compiles quite alright, but won't execute when I try the lookup. It fails on lookup, What more do I need 2 be doing. I can access the bean using a JSP page but not via client stub code????
import testing.*;
import javax.naming.InitialContext;
public class TestClient
public static void main(String [] args){
     try {
     InitialContext ic = new InitialContext();
     Object o = ic.lookup ("ejb/TestingBean");
     } catch (Exception e) {
     System.err.println ("Some weird asss exception occurred");
     e.printStackTrace();
}

The best option is to write a portable Java EE Application Client component and let the Application Client container bootstrap the naming service so your code doesn't have to. If you prefer to write a non-portable stand-alone java client, we have instructions for how to do that here :

Jndi.properties - javax.naming.NoInitialContextException

hi
i'm new to netbeans (5.5) and the Sun 9 appserver. I've been using JBoss & Eclipse to date.
I'm getting the javax.naming.NoInitialContextException and I believe it's because I'm not using jndi.properties like in jboss.
The problem is that I cannot seem to find where it should go and what it should look like.
Can someone please help ?
Thanks

All the documentation you need is here:
http://docs.sun.com/app/docs/coll/1343.3
I would particularly point you to http://docs.sun.com/app/docs/doc/819-3659/6n5s6m5bn?a=view

Javax.naming.NoInitialContextException! Urgent help needed

Hi All
I'm using Oracle Application Server(OC4J) for J2EE. i created an application of Stateless Session Bean & tested on j2sdkee1.3.1, & it is working fine on it. Same Application (an .ear file) i deployed on OC4J. But it is giving an error NoInitialContextException, lookup fails here.
Application contains method getEchoString(String):String & a index.jsp page calling a bean's method.
Can anybody tell me the solution to get handle of beans home interface for calling method.
Already i've wasted many days for this. Plz help. It's urgent
Thanks in Advance

To the best of my knowledge, the 'javax.naming.ldap' package is fairly new, and is only included in the most recent distributions of the JNDI API. I know that this package is included with J2SDK 1.3, and I can also confirm that the very latest JNDI distribution (from http://java.sun.com/products/jndi/#download) contains the package.
Good luck,
-Derek
