I am using resty gwt jar and i have included that jar from add external jar.I have also included in the gwt.xml as (<inherits name='org.fusesource.restygwt.RestyGWT'/>).I have also added that jar in war file lib folder. I have used one interface which extends restservice,in this interface while debugging i found that in the line i am getting nullpointerexception.

Please help me why i am getting this error?

Answer 1

Are you sure restyGWT jar is in your classpath ?

Can you post the code of your PersonResourceAsync ? Does it extends the RestService interface ?
