Impact of version change of JDK/SDK

[Rakesh Chowdhury]

hello Friends,

I have a query on the JDK version.

I am working in a core java application where present server is residing on NT. Now it is shifted to Windows 2003. It is an applet which is running on the client's applet viewer, install the jar files from the server and hit the server when ever required. The application needs the Java "SDK 1.3.1_06". Presently it downloads the jar files among them it holds xercies.jar, xercesImpl.jar also.

If I change the version of JDK to 1.4 or higher, do I need to download the xercies.jar, xercesImpl.jar two jar files again? I come to know that If JDK version 1.4 or higher is being used, this 2 jars are optional, since JDK 1.4 includes a built-in JAXP-compliant parser.

Is there anybody who can confirm that?
And what is impact on the change of JDK version on the application existing code? Will it make any impact on the threading?
Please help. Thanks in advance.

Yes, Java 1.4 contains a JAXP-compliant parser. I think it's not Xerces, though, but Crimson. But as long as the code sticks to JAXP functionality, it should work fine.

As for other changes, well, in general the code should continue to run fine. You will need to test that, of course.
