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 .
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:247)

        at javax.naming.InitialContext.lookup(InitialContext.java:351)
        at SimpleSessionClient.Main.main(Main.java:33)
BUILD SUCCESSFUL (total time: 21 seconds)
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.

Javax.naming.NoInitialContextException: Cannot instantiate

IHi,
Iam trying to run my first application on WEBLOGIC SERVER 8.1. I have already deploed class file on server.i have already set path for my client jar .

appserv-rt.jar already contains a jndi.properties file, and users don't need to worry about anything about jndi.properties file. For your sample app, it should work when you have appserv-rt.jar and javaee.jar in classpath.
If you still have failures, pls post your complete command you used to run client.

EJB ERR: Namingexception caught:javax.naming.NoInitialContextException

Hi,
I am trying to deploy a sample ejb on Jboss and trying to call it from a client.
I am getting the following error.
*********Before LookUP*********
Namingexception caught:javax.naming.NoInitialContextException: Need to specify c

Am I missing something here?
Is there any other way to go about this. Any help would be greatly appreciated.

Javax.naming.NoInitialContextException ERROR

I get the following error:
Naming exception Error while connecting to the database : 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
I created a Java class which has a method which connects to the database using:
InitialContext ctx = new InitialContext();
javax.sql.DataSource ds = (javax.sql.DataSource)ctx.lookup("jdbc/TMBLDB01CoreDS");
m_connection = ds.getConnection();
It errored out on the second line with the above error. I am using JDeveloper 10.1.3.
I got it to work with a JDBC connection but prefer to use JNDI with JDBC.
I started the Oracle AS Containers for J2EE (OC4J) by double clicking start_oc4j.bat.
What is missing to make this work?

Yes by adding the following solved that issue.
env.put(JboContext.DEPLOY_PLATFORM, JboContext.PLATFORM_LOCAL);Another thing is I have added BC4J Client as library to my project. When I run I am getting

Javax.naming.NoInitialContextException when invoking an EJB

Hi,
I've deployed a stateless session EJB in oc4j and invoking it thru a Java client. I'm using Eclipse. I've a jndi.properties in config folder of my application which is in the classpath of the client code.
The jndi.properties has :
java.naming.factory.initial=com.evermind.server.rmi.RMIInitialContextFactory
java.naming.provider.url=ormi://<localhost>:12401/OC4JEJB
java.naming.security.principal=oc4jadmin
java.naming.security.credentials=oc4jadmin
where OC4JEJB is the application name deployed in oc4j.
This jndi.properties file is in the classpath.
My client code is :
Server server = null; //interface
ServerHome testSessionBean; //implementation of methods in Server interface
try {
Context ctx = new InitialContext();
Object objref = ctx.lookup("EJBServer"); //JNDI name
Object obj = PortableRemoteObject.narrow(objref, ServerHome.class);
testSessionBean = (ServerHome) PortableRemoteObject.narrow(objref,
                         ServerHome.class);
server = testSessionBean.create();
} catch (...) { }
When i set the properties and do a look up
Properties env = new Properties();
env.put(Context.INITIAL_CONTEXT_FACTORY,
          "com.evermind.server.rmi.RMIInitialContextFactory");
env.put(Context.SECURITY_PRINCIPAL, "oc4jadmin");//oc4jadmin
env.put(Context.SECURITY_CREDENTIALS, "oc4jadmin");
env.put(Context.PROVIDER_URL,
     "ormi://<localhost>:12401/OC4JEJB");
InitialContext ctx = new InitialContext(env);
it works perfectly fine.
But when i use the jndi.properties it gives the following exception.
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

I've tried placing the jndi.properties in j2ee/home/applib too. Where shud i place this jndi.properties and invoke the EJB?
Could anyone help resolve this issue?
Thanks in advance,
Sprightee

Try add your jndi.properties to your CLASSPATH.
See this doc for more details of RMI.

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

The server deploy EJB but I run EJB Client program,The error msg is can't find JNDI

Hi all:
I am using Weblogic 6.1/SP2. I use the console to start
server and deploy EJB jar,from the msg I see my EJB jar
been deployed. When I run EJB Client program, the error
msg is can't find JNDI name t3://URL:11003.....
I check my ejb-jar.xml amd weblogic-ejb-jar.xml are fine.
Last week I did deploy EJB and ran the client both
suceessful. Any ideas, Thank you.

Sabha:
Thank you for your help info, I soloved the problem.
The problem is the ejb jar was deleted(I don't why)
then System Admin to deploy EJB jar from Admin console.
After that everything is fine.
"Sabha" <[email protected]> wrote:
Run weblogic.Admin -url ... LIST to see whether the JNDI name is there

you can view the jndi tree of the server from the console (right click

server name) and check whether the ejb home is bound to the correct jndi
name.

Hi Albert,
I would double check to make sure the EJB was indeed deployed (check
server log). What message did you see that leads you to believe itwas
successfully deployed? Also, verify the JNDI name you are lookingup in
your client matches the JNDI name for the EJB. If this doesn't solve
the problem, please post the error message and stack trace you are
seeing on the client.

How to get rid of "javax.naming.NoInitialContextException"

Hi,
Iam learning ejb. I was practicing the stateless session bean. I wrote a sample hello world application. While executing the client am getting the following error.

please suggest me a solution. what has gone wrong!!

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

I wrote a simple test EJB as a SessionBean using the beta2 release of the 1.3 j2ee sdk. After building and deploying the EJB I wrote the following code in a separate client application:
InitialContext ctx = new InitialContext();
Object o = ctx.lookup("java:comp/env/ejb/myejb");
My problem is that the call to lookup always generates the following error:
javax.naming.NoInitialContextException: Need to specify class name in environmen
t or system property, or as an applet parameter, or in an application resource file: java.naming.factory.initial
A j2ee server is running on my localhost.
Does anyone have any ideas?

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.

Javax.naming.NoInitialContextException - jndi.properties

I created an Enterprise application and deployed an Ejb project to the JBoss server.When I try to connect to the JNDI like this:
Object o = initialContext.lookup(JNDI_NAME); I get this exception:
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
I put the jndi.properties file both into the client app and the bean project, near the .java files.
here is the jndi.properties file:
java.naming.factory.initial=org.jnp.interfaces.NamingContextFactory
java.naming.provider.url=http://localhost:1099
java.naming.factory.url.pkgs=org.jboss.naming:org.jnp.interfaces
I'm really confused...
thanks..

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!

Refer to the Sun App Server documentation.

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: Need to specify class name...

Hello,
I am trying to use a Database Connection Pool.
Here is the test class am using to verify the connection pool:
public static void main(String[] args) { Connection connection = null; try { InitialContext initialContext = new InitialContext(); DataSource dataSource = (DataSource)initialContext.lookup("jdbc/<alias>"); connection= dataSource.getConnection(); } catch (SQLException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (NamingException e) { // TODO Auto-generated catch block e.printStackTrace(); } Statement stmt = null; try { String query = ""; stmt = connection.createStatement(); ResultSet resultSet = null; query = "SELECT <column> ...'"; resultSet = stmt.executeQuery(query); while(resultSet.next()){ System.out.println(resultSet.getString(<column>)); } stmt.close(); stmt = null; connection.close(); connection = null; } catch (SQLException e1) { // TODO Auto-generated catch block e1.printStackTrace(); }finally{ if (stmt != null) { try { stmt.close(); } catch (SQLException sqlex) { // ignore -- as we can't do anything about it here } stmt = null; } if (connection != null) { try { connection.close(); } catch (SQLException sqlex) { // ignore -- as we can't do anything about it here } connection = null; } } }
I get following exception..
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:640) at javax.naming.InitialContext.getDefaultInitCtx(InitialContext.java:243) at javax.naming.InitialContext.getURLOrDefaultInitCtx(InitialContext.java:280) at javax.naming.InitialContext.lookup(InitialContext.java:347) at com.internal.test.TestRun.main(TestRun.java:53) java.lang.NullPointerException at com.internal.test.TestRun.main(TestRun.java:66) Exception in thread "main"
The exception points to
DataSource dataSource = (DataSource)initialContext.lookup("jdbc/OrderStatus");
Is this the correct way to test...?
Thanks

You can't access a jdbc pool like that (simply with a main method).
The Database connection pool must be managed by a container (a servlet or application server) like tomcat.
That is not entirely true but it certainly helps and is generally the only way it is used anyway so one might as well do it.
