I am using xml (xalan and xerces) for a server side java application. Whenever a user sends a request to net based server application, the java beans on the server side create a DOMParser object, do data processing on xml data files and returns response. a. I am little concerned since for each request the DOMParser object is created and DOM processing is done. (Well certain cases I can use SAX. But for time being let's assume, that I must use DOM) Is this a right approach? Can pooling of DOMParser object be done? or I would put it this way; should parser instances be pooled? (like database connections) b. In the same application I have another scenario; In the JSP files I use xalan transformer object to perform XSL transformation on certain xml data. Now this happens for each JSP request. Is this a normal practice? how can this be made efficient/less memory foot print/less runtime memory usage ? regards haresh
