How can I change the sdk version of Websphere 4 if I already install it

[Ricardo Alvarado]

MMM... I got another question....
I'm using WebSphere 4 and I need to use the newest sdk version for it. I already installed and I wish to change only the version in the websphere application developer.
I think this is possible, like it used to be an easy way with JBuilder.
Where o how can I change the SDK (JDK) version???
I need to upgrade the version because I need to use jaxr and jax-rpc
Thanks

Can't be done. Don't try it. You must upgrade to a later version.

Well, if it can't be done, can I at least use the libraries , (or some of them) of apache...
the org.apache.xmlrpc.* ???
Or that is not posible also....
If that is not possible, in the WebSphere version 4, how can I use the XML-RPC methods??? Are any implemented for WebSphere ...
Maybe I'm looking in the wrong place.
Could you help me.
Thank you, I'll really appreciate all your help.

Well, it depends on what you really want to do. If you want to do Web Services, well, that's already included in WSAD 4 with Apache SOAP. If you want to do XML-RPC instead, just download the apache classes and add them to your classpath -- you don't need a new JDK or SDK for that.

Thank you very much Kyle, I'm gonna try that.
I really appreciate it.
Thanks.

How can I add that to the classpath. Can you help me with that. Were I can find that. Thank you very much

[Kyle Brown]

Ricardo,
Tell me WHAT you really want to do. Are you trying to develop a Web Service, or use XML-RPC? You've asked for two different things. Rather than give you detailed instructions on doing something that won't solve your problem, I'd like to know what problem you're trying to solve so that I can give you the right advice.

I'm trying to develop XML-RPC
Trying to communicate a C program as server running in a Unix system with a Java program using WebSphere as client.

[Kyle Brown]

Is this client a Servlet or an EJB in WebSphere? (yes, it matters...)
Kyle

[Ricardo Alvarado]

Its a servlet...

OK, then it's easy. Download the Apache XML-RPC classes and add them into the "lib" directory of your WAR file. The way you do this is to select the "lib" directory of your WAR project in WSAD and then select File->Import and choose "File System" as the import type. Find your JAR files in the upper chooser and make sure the target directory is the "lib" directory of your WAR project.
That should work well enough to suit your purposes. Now, my strong recommendation to you is that you need to buy a book on using WSAD -- either Howard Kushner's, Igor Livkin's, or mine. This is the kind of thing that they all cover.

Thank you kyle, I will do that.
I was a little lost on this. I remember that I did that with the jdbc classes for Oracle Connection.
Thank you.
