Where is class weblogic.jndi.WLInitialContextFacto

问题:

when trying to execute my jar file I get an exception:

javax.naming.NoInitialContextException: Cannot instantiate class: weblogic.jndi.WLInitialContextFactory 
[Root exception is java.lang.ClassNotFoundException: weblogic.jndi.WLInitialContextFactory]

I guess this is some kind of missing library on the classpath. Can anyone tell me which jar-file is missing? I can't find the class weblogic.jndi.WLInitialContextFactory anywhere...

Thanks!

P.S.: I already have weblogic 10.0 jar included.

Check your server/lib/ folder to find wliclient.jar.

With Weblogic 12.1.3, you can find it here:
${INSTALL_DIR}/inventory/wlserver/server/lib/wlclient.jar

回答2:

Step 1:

Go to E:\weblogic81\user_projects\domains\mydomain. Then type Setenv command. As follows

E:\weblogic81\user_projects\domains\mydomain>setenv 

Step 2:

Weblogic.jar file is needed by your client application. It may contain in the following path E:\weblogic81\weblogic81\server\lib\weblogic.jar. so set the classpath for the this folder or copy this weblogic.jar file into your application-folder so that weblogic.jar file is available to your application first.

E:\weblogic81\user_projects\domains\mydomain>set CLASSPATH=%CLASSPATH%;E:\weblogic81\weblogic81\server\lib;.

Step 3:

Go to domain folder in command prompt as shown above and set classpath. To not to disturb other classpaths set classpath as:

set CLASSPATH=%CLASSPATH%;E:\weblogic81\weblogic81\server\lib;.

Here (.) dot represents set classpath to current directory.

Step 4:

After classpath set run command STARTWEBLOGIC as follows:

E:\weblogic81\user_projects\domains\mydomain>STARTWEBLOGIC 

Step 5:

Do not login to weblogic server. If you are already login just log out and write the following code in myeclipse or some other IDE.

Step 6:

package directory.service;
import java.util.*;
import weblogic.jndi.*;
import java.io.FileInputStream;
import javax.naming.*;
public class GetInitContext {

    /**
     * @param args
     */

    public static void main(String[] args) {


        try{
        weblogic.jndi.Environment env=new weblogic.jndi.Environment();
    weblogic.jndi.Environment environment = new weblogic.jndi.Environment();
        environment.setInitialContextFactory(
          weblogic.jndi.Environment.DEFAULT_INITIAL_CONTEXT_FACTORY);
        env.setProviderUrl("t3://localhost:7001");
        env.setSecurityPrincipal("agni");
        env.setSecurityCredentials("agnidevam");
        Context context=env.getInitialContext();
        System.out.println("got the initial context for weblogic server---> "+context);
        context.createSubcontext("sone");
        context.bind("agni one",new Integer(10));
        context.createSubcontext("sone/sctwo");
        context.bind("agni two",new Integer(20));
        context.createSubcontext("sone/sctwo/scthree");
        context.bind("agni three",new Integer(30));
        System.out.println("subcontex object created please check in admin server for more details");

        }
        catch(Exception e){
            System.out.println("file inputstream exception  ---> "+e);
        }
    }

}

Step 7:

Execute the above code and login to weblogic and right click on myserver>view jndi tree> you find the bound objects information.

Check the following tag in your build.xml

property name="WLS_HOME" value="${env.WLS_HOME}"

where WLS_HOME=c:\weblogic\wls\wlserver if running on windows i kept trying to run a simple hello world program and it kept throwing

*run:

 [echo] Executing client class  
 [java] javax.naming.NoInitialContextException: Cannot instantiate class: weblogic.jndi.WLInitialContextFactory [Root exception is java.lang.ClassNotFoundException: weblogic.jndi.WLInitialContextFactory]*

once i changed the above mentioned tag it in the build.xml it worked fine

回答4:

it looks you are doing a JNDI lookup outside of WLS.

You need to use wlfulclient.jar or if your machine has a WLS installation then add to your classpath project: WL_HOME/server/lib/weblogic.jar

回答5:

I faced the same issue and it's fixed now :)

The fix is, to go to WebLogic server and navigate to /Oracle/Middleware/wlserver_10.3/server/lib/ and execute the below command.

Command: java -jar wljarbuilder.jar -profile wlfullclient5

The above command creates a jar file with all the jar's inside WebLogic server /lib folder and place it in your client java code build path Eclipse and craetes runnable JAR file and place this wlfullclient5.jar file in server/lib folder as well.

Hope this helps! Kindly let me know if you have any issues.

回答6:

Adding wlserver/server/lib/weblogic.jar is enough. I test it.

回答7:

It is packaged inside of the weblogic.jar under your server/lib.

回答8:

in version 12c it is located in weblogic-classes.jar in your lib directory:

C:\wls1213\wlserver\server\lib
