The values of the arguments should be XObject instances not String instances.
You need to modify the code like this:

XSLTProcessor processor = XSLTProcessorFactory.getProcessor();
XObject category = processor.createXString(request.getParameter("category"));
...
processor.setStylesheetParam("category", category);


Hope this helps,
