I use apache fop in a servlet to display some xml as pdf. When I have used
that functionality in my webapp my (Tomcat 6.0) web container doesn't want
to undeploy. It deletes everything in the webapps/*context* directory except
WEB-INF/lib/batik.jar and WEB-INF/lib/fop.jar. When trying to delete the
files manually windows tells me they are in use.
I use this code to render the xml into pdf
ByteArrayOutputStream out = new ByteArrayOutputStream();
FopFactory ff=FopFactory.newInstance();
TransformerFactory tf=TransformerFactory.newInstance();
StreamSource xslfo=new
StreamSource(this.getServletContext().getRealPath("lid-pdf.xsl"));
try {
Transformer tt=tf.newTransformer(xslfo);
Fop fp=ff.newFop(MimeConstants.MIME_PDF, out);
SAXResult res=new SAXResult(fp.getDefaultHandler());
Source src= new DOMSource(doc);
DOMResult dd=new DOMResult();
assert(src!=null);
assert(res!=null);
tt.transform(src, dd);
Transformer t2=tf.newTransformer();
// System.out.println(res.getNode().getFirstChild());
t2.transform(new DOMSource(dd.getNode()), res );
//Prepare response
response.setContentType("application/pdf");
assert(out.size()>0);
response.setContentLength(out.size());
// System.out.println(Version.getVersion());
//Send content to Browser
response.getOutputStream().write(out.toByteArray());
response.getOutputStream().flush();
out.close();
} catch (FOPException e) {
// TODO Auto-generated catch block
throw new ServletException(e);
} catch (TransformerConfigurationException e1) {
// TODO Auto-generated catch block
throw new ServletException(e1);
} catch (TransformerException e) {
// TODO Auto-generated catch block
throw new ServletException(e);
}
System.gc();
Anyone has any ideas?
