I downloaded xstream jar and sourcecode and append the sourcecode into jar file using winrar

and i created 2 gwt.xml files.

xstream.gwt.xml is present in com.thoughtworks 

<?xml version="1.0" encoding="UTF-8"?> 
<module> 
<source path="xstream"/> 
</module>

and operations.gwt.xml is present in com.thoughworks.xstream 

<?xml version="1.0" encoding="UTF-8"?> 
<module> 
<source path="annotations"/> 
<source path="converters"/> 
<source path="core"/> 
<source path="io"/> 
<source path="mapper"/> 
<source path="persistence"/> 
</module>

Edited: its my gwt project xml

<?xml version="1.0" encoding="UTF-8"?>
<module rename-to='test'>
  <inherits name='com.google.gwt.user.User'/>
  <inherits name='com.google.gwt.user.theme.standard.Standard'/>
  <inherits name='com.thoughtworks.xstream'/>
  <entry-point class='com.example.test.client.Index'/>
</module>

but i got an error 

Compiling module com.example.test.Test

      Ignored 142 units with compilation errors in first pass.

  • add .gwt.xml file code also – Parvathy Jan 29 '13 at 09:51
  • Errors in 'jar:file:/C:/Users/YRC/Downloads/xstream-1.4.4.jar!/com/thoughtworks/xstream/XStream.java' have you opend Xstream.java file ?? any errors ? – Suresh Atta Jan 29 '13 at 11:04
  • @Bucks now u have source stream. so open it in a new prjt in eclipse or netbeans and find error. may it need other jar. and gwt is not supporting all jars. I opened it i saw File. but we cant use File in client side. So use it in server side – Parvathy Jan 29 '13 at 11:42
  • @Parvathy can you please link any example for using that in server side – Bucks Jan 29 '13 at 12:37

You cannot use reflection in GWT;

  • getDeclaredFields

  • getDeclaredMethod

  • forName

  • getConstructor

and the likes ... are all reflective calls;

GWt not supporting all code in client side so we can use it in server. GWT supporting RPC. http://www.vogella.com/articles/GWT/article.html or refer https://developers.google.com/web-toolkit/doc/latest/DevGuideServerCommunication

what you have to do is include all jar in lib and configure build path and only use this code in server side.
