Parsing file over the network

Question

We are using Xerces implementation of jaxp - (xercesImpl.jar, xmlParserAPIs.jar).
Below is my code:
DocumentBuilder builder = getBuilder();
java.io.FileInputStream fi = new java.io.FileInputStream(�file://c$/config/tmp.xml�);
     org.w3c.dom.Document outNode = builder.parse(fi);
     fi.close();
Inside the tmp.xml is reference to tmp.dtd without specifying any path, just tmp.dtd. The line of code that parses the file throws exception that it can�t find tmp.dtd and it shows me the path where it expects it to be � it is a current user directory. Is there a way of telling the implementation to look somewhere else for files referenced by the file being parsed?.

Answer 1

yes, intercept the calls to the DTD and point the parser to the right file:
builder.setEntityResolver(new EntityResolver() {
  public InputSource resolveEntity(java.lang.String publicId, java.lang.String systemId)
         throws SAXException, java.io.IOException
    if (systemId.endsWith(".dtd"))
      return new InputSource(new FileInputStream("mypath/"+systemId));
    else return null;
