Question

I got this compilation error during my GWT Compilation. I am using this to parse an XML document.

[ERROR] Line 24: No source code is available for type org.w3c.dom.Node; did you forget to     inherit a required module?
[ERROR] Line 28: No source code is available for type org.w3c.dom.NodeList; did you forget to inherit a required module?
[ERROR] Aborting compile due to errors in some input files

From whatever research i did regarding this it says the classpath might be missing, but since this will be included by default in gwt-user.jar and JRE7, and i have not included any external jars also, so no case of duplicates ! And you cannot have these type of codes in Client side code since it will be converted to javascript

I have a class which makes use of this Node in my shared folder (GWT Model View Presenter Project structure ), which is basically a model !

1. Is moving the code to server side is the only possible solution?

2. If 1 is true, how would i be able to refactor my client side presenters accessing this model without the over head of RPC call everytime ?

3. Are there any alternate approaches to this ?

My GWT config file.

 <module rename-to='xxxxx'>
 <inherits name='com.google.gwt.user.User'/>


 <inherits name='com.google.gwt.user.theme.standard.Standard'/> 
 <inherits name="com.google.gwt.xml.XML" />

  <entry-point class='com.xxxx.xxxxx.gwt.client.ProjectEntry'/>


  <source path='client'/>
  <source path='shared'/>

 </module>

Edit : I have included the xml inherits now ! Its working

Answer 1

somewhere in your code base you are using org.w3c.dom.Node and org.w3c.dom.NodeList these are not white listed. In other words you can not use these classes! see;

https://developers.google.com/web-toolkit/doc/latest/RefJreEmulation

you should use these packages for xml;

import com.google.gwt.xml.client.Document;
import com.google.gwt.xml.client.Element;
import com.google.gwt.xml.client.Node;
import com.google.gwt.xml.client.NodeList;
import com.google.gwt.xml.client.XMLParser;
