**Background**
I am php & frontend web developer developing an application in Java using Netbeans to read from a websphere (V8.5 I think) JMS queue and then issue commands to appropriate scripts/servers. This is my first major run in with Java for about 10 years so please bear with me. My initial test application runs fine on the server that hosts the jms queue but I have been running into one error after another when trying to connect from a remote location (which at the moment happens to be windows but will be linux in the end). I have been battling through both my lack of experience with Java the process of diagnosing jar issues and locating apparently needed jars from websphere and elsewhere but have finally reached a brick wall. I have seen lots of answers that consist of statements such as "you need the right jar files", but not saying which ones or you need thisone.jar and all the jars that one refers to. I don't know how to find out what jars that should be. I have read posts that say that the process should work with only some of the jars in my library. Am completely stuck...

**Error**
The error which I am having no luck in getting through

```
 javax.naming.NamingException: Failed to initialize the ORB [Root
 exception is org.omg.CORBA.INITIALIZE: can't instantiate default ORB
 implementation com.ibm.CORBA.iiop.ORB

The full rest of message is this

**What I am doing**
I have added the following jars to the library

```
javax.jms-1.1.jar 
com.ibm.ws.orb_8.5.0.jar 
com.ibm.ws.ejb.thinclient_8.5.0.jar 
com.ibm.was.sib.client.thin.jms_8.5.0.jar 
com.ibm.was.admin.client_8.5.0.jar 
com.ibm.ws.messagingClient.ja

```

I have also read that the following jars are needed

```
sibc.jms.jar
sibc.jndi.jar
sibc.orb.jar

```

I have located these and added them also, although I have also read that these are not needed if you have the thin client I already have. 

and am using JDK1.7

```
context factory: com.ibm.websphere.naming.WsnInitialContextFactory 
Provider URL: corbaloc:iiop:192.168.254.202:2809

```

The context is being created. But am unable to make the queue factory connection. I can create a socket to the ip address and post using a quick test application.

**The Code**
Here is the class file and all the connectiony bits. It is complete work in progress.
