SOAP Liason configurability and validation

[Ozzie-Mailing Lists <oz...@hotmail.com>]

Apache's SOAP server already parses every message automatically using DOM. As far as I can see, there is no way to turn on validation for this internal parsing process. It seems as though, you can plug-in a new parser liason with your own parser settings. However, that whole process of specifying a new plug-in parser is also tainted. Look at the following code that checks for the plug-in (notice the comments that I added),

// code from init() method of MessageRouterServlet.java
//
        if (System.getProperty(TRANSPORT_HOOK_EXTENSION) != null) {
//
// why do i need to specify TRANSPORT_HOOK_EXTENSION just to achieve a new parser???
//
            EnvelopeEditorFactory factory =
            (EnvelopeEditorFactory)createObject(ENVELOPE_EDITOR_FACTORY);
            if (factory != null) {
                try {
                    Properties props = new Properties();
                    Enumeration enum = getServletConfig().getInitParameterNames();
                    while(enum.hasMoreElements()) {
                        String name = (String)enum.nextElement();
                        if (!ENVELOPE_EDITOR_FACTORY.equals(name) &&
                        !XML_PARSER.equals(name))
                            props.put(name,
                            getServletConfig().getInitParameter(name));
                    }
                    editor = factory.create(props);
                } catch (SOAPException e) {
                    System.err.println("WARNING: Can't create editor: " +
                    e.getMessage());
                }
            }
//
// why isn't this statement outside the transport hook check? what if i want
// my own parser liason????
//
            if ((xpl = (XMLParserLiaison)createObject(XML_PARSER)) == null)
                xpl = new XercesParserLiaison();
        }

Maybe I am missing something from above. I would expect that I can turn on validation in the existing liasion and also create my own liason.

Subject: How to turn on Schema Validation


Is there a simple way to turn on schema validation for the messages being received? I couldn't find a way but to modify XercesParserLiason.java itself. I am assuming there is a much simpler way to turn on validation. Since Apache's SOAP server already parses the message using DOM, I really don't want to re-run the parser just for validation.
