[xsl] All Streams are being closed by Xalan
Subject: [xsl] All Streams are being closed by Xalan From: "Mercieca, Michael" <Michael.Mercieca@xxxxxxxxxxxx> Date: Mon, 21 Oct 2002 10:56:26 -0600 |
Hello. I saw that the post at http://sources.redhat.com/ml/xsl-list/2001-08/msg00632.html was similar to a problem that I am having. I am writing a servlet. What I want to do is take the XML request posted to it and run a transformation on it. The result of that transformation goes to another servlet which does some work and returns some XML. I then need to run a second transformation (with the initial XML request being the source) that takes combines data from both the initial XML request and the response from the servlet that I posted to. (Hope that's not too confusing). I was initially letting Xalan create the StreamSource using the following code: int x = 999999999; BufferedInputStream isInitial = new BufferedInputStream(request.getInputStream()); isInitial.mark(x); TransformerFactory tf = TransformerFactory.newInstance(); Transformer trans1 = tf.newTransformer(new StreamSource(eQuote2RS_xslt)); trans1.transform(new StreamSource(isInitial),new StreamResult(outToServlet2)); //this part worked fine, but when tried to reset the BufferedInputStream, I got an IOException saying that it was closed. isInitial.reset(); //threw the IOException. I then read the aforementioned post on xsl-list, and saw that Xalan would close the stream unless it was created manually. So I then tried to do that using the following code. BufferedInputStream bisInitial = new BufferedInputStream(req.getInputStream()); StreamSource ssInitial= new StreamSource (bisInitial); bisInitial.mark(x); TransformerFactory tf = TransformerFactory.newInstance(); Transformer trans1 = tf.newTransformer(new StreamSource(eQuote2RS_xslt)); trans1.transform(isInitial,new StreamResult(outToServlet2)); bisInitial.reset(); //still throws the IOException. It seems that Xalan is closing my stream no matter how I create it. I guess I could write it out to a file and open it twice, but that really seems like a waste. Does anyone know what I'm doing wrong, or know of another way of doing this??? Any assistance is greatly appreciated. Mike Mercieca XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
