cannot use xml mode in iweb or pwAdmin

I have tried using xml mode in pwAdmin but when i click on it, it does not open. Also when i try to use xml role in iWeb but it doesn't show up. I spoke with Drakaer and he said i needed jdk 1.5 so i added it into my java folder and it seemed to of messed up my pwAdmin as in it showed all the tabs at the bottom of the screen and when i clicked on them nothing would happen. After that i changed the java home paths to what drakaer said and pwAdmin would show up as a broken links so would iWeb (but the root directory was fine). I will be re-importing the server into stock hrace009's image and changing everything back to what it was (as i didnt back up my edited server before changing the java's etc...)

Can anybody point out what i need to do to get Xml editing available?

Many Thanks
