Regarding Xml creation in Weblogic 9.1

[Yogaraj Khanal]

Hi,
I am wasting lot of my time in java environment configuration.I want to know how to create Xml files using Weblogic 9.1.Also my weblogic application server is too slow.I am able to deploy applicaiton using Weblogic 8.1 and jdk 1.4 but i want to do same using Weblogic 9.1 and jdk 1.5.The problem I am facing with this upgrade is creation of Xml files using weblogic 9.1 which I was doing by using weblogic builder in 8.1.
Can any one share and suggest me the solution of this problem.
