[AXIS2 1.3] REST problem
Hi all :
I'm developing a web service using the POJO approach. I have a
method like this :
class TestingClass {
...
public String testing(String param1, String param2) {
System.out.println("message");
return param1 + " " + param2;
}
...
}
I've coded a RPC client and it works fine. Then I've tried to call
the service using REST like this :
http://localhost:8080/axis2/services/TestingClass/testing?param1=hi¶m2=all
Then it fails with this exception :
java.util.ConcurrentModificationException
java.util.HashMap$HashIterator.nextEntry(Unknown Source)
java.util.HashMap$KeyIterator.next(Unknown Source)
org.apache.axis2.builder.BuilderUtil.buildsoapMessage(BuilderUtil.java:92)
org.apache.axis2.builder.XFormURLEncodedBuilder.processDocument(XFormURLEncodedBuilder.java:100)
org.apache.axis2.transport.TransportUtils.createSOAPMessage(TransportUtils.java:130)
org.apache.axis2.transport.http.util.RESTUtil.processURLRequest(RESTUtil.java:98)
org.apache.axis2.transport.http.AxisServlet$ProcessRESTRequest.processURLRequest(AxisServlet.java:776)
org.apache.axis2.transport.http.AxisServlet.doGet(AxisServlet.java:238)
javax.servlet.http.HttpServlet.service(HttpServlet.java:689)
javax.servlet.http.HttpServlet.service(HttpServlet.java:802)
I've searched in the Tomcat logs but I couldn't find more info. Any
idea of what could be happening here?. Thanks in advance.

Hi :
First of all, THANKS A LOT, Charitha and Keith for your help!!.
Finally, Keith was right. I've downloaded Axis2 1.3 and I thought I
was using it, but I was really using the old Axis2 1.2. So, I've moved
to Axis2 1.3 and the problem has gone.
Thanks again for you help!!.

Hi Albert,
Can you make sure that you are using Axis2-1.3. A issue similar to this was
fixed on the Axis2 trunk before the Axis2-1.3 release (
http://issues.apache.org/jira/browse/AXIS2-2662).
I went through your stack trace it is identical to the one given in the JIRA
(which makes me think that you are using Axis2-1.2 and not 1.3). Also line
92 of BuilderUtil in the 1.3 source is a null check which confirms that your
not using 1.3. Please download Axis2-1.3 and give a try it should work for
you.
Thanks,
Keith.

Hello Albert,
I tried to reproduce your issue with Axis2-1.3(Winxp/jdk15). However, I
was able to invoke your service (A service impl class with more than one
method) in RESTful manner without having any issue. Please try again in
a fresh environment and if u can reproduce the issue in successive
calls, report a JIRA http://issues.apache.org/jira/browse/AXIS2
regards
Charitha

I've new info. If I comment all the class except the testing method,
it works fine with REST. If I uncomment another method like this :
class TestingClass {
public MyTestingData anotherMethod(String param1, String param2,
String param3) {
return new MyTestingData(param1, param2, param3);
}
public String testing(String param1, String param2) {
System.out.println("message");
return param1 + " " + param2;
}
}
Then, the REST call to the testing method fails with the exception
on the previous post, but it works fine with the RPC client. Any
idea?. Thanks in advance.
