An error is reported when eclipse is started.

Download the latest version eclipse3.0 from a few days ago and decompress it to the D:/eclipse directory, A prompt box pops up at startup, indicating that an error occurred. Please refer to the ******** under Eclipse/configuration *******. log File.
The file says:

Eclipse. buildid = i200405211200

The problem is simple: javax. xml. parsers. saxparserfactory cannot be found. What's wrong? My java. version is 1.4.1. Why is it 1.3.1 ?! Think about it, it is to install an orcale9 client, is it from it?

Run the CMD command, path + press enter, and output the following results: D:/Oracle/ora92/bin; G:/program files/Oracle/JRE/1.3.1/bin; G: /program files/Oracle/JRE/1.1.8/bin; % SystemRoot %/system32; % SystemRoot %/system32/WBEM; D:/Borland/jbuilderx/jdk1.4

Set path to D:/Oracle/ora92/bin; % java_home %/JRE/bin; % SystemRoot %/system32; % SystemRoot %; % SystemRoot %/system32/wbems

Restart eclipse, OK, OK !!!

I am afraid to break down orcale and run it again. Well, the Java version is also annoying!
