Re: No source code is available for type javax.xml.parsers.DocumentBuilderFactory

Hi I tried using XMLParser as u suggested. But getting this error.

The code is

public void onModuleLoad() {
    
        xmlstring = callquery.xmlget_capabilities();
        System.out.println(xmlstring);

        System.out.println(xmlstring.

length());

        
        xmldoc = XMLParser.parse(xmlstring); \\ Error at this line
        Element root = xmldoc.getDocumentElement();
        System.out.println("Element = "+ root.getNodeName());  
    }

See Development Mode for details.

In general you can only use Java classes on the client side (everything that is in your client and shared package) listed in: http://code.google.com/intl/de-DE/webtoolkit/doc/latest/RefJreEmulation.html

So you can not use most of the classes in your code on client side. 

You have to:

- use XMLParser (http://google-web-toolkit.googlecode.com/svn/javadoc/2.3/com/google/gwt/xml/client/XMLParser.html)

- write your own client side string parser that converts the xml string to something you want to have 

- parse the XML on server side and ask the server for the information you need

I haven't used XMLParser yet but it seems to me that the xml string you want to parse isn't that long so I think it should work.
