[jira] Resolved: (AXIS2-600) Axis can't perform reflection on
updated .class file with hotupdate
[ http://issues.apache.org/jira/browse/AXIS2-600?page=all ]
Deepal Jayasinghe resolved AXIS2-600:
-------------------------------------
Resolution: Fixed
User confirmed that he doe not have the bug in RC4
(his problem seems to have gone away in 1.0 RC4,)
> Axis can't perform reflection on updated .class file with hotupdate
> -------------------------------------------------------------------
>
> Key: AXIS2-600
> URL: http://issues.apache.org/jira/browse/AXIS2-600
> Project: Apache Axis 2.0 (Axis2)
> Type: Bug
> Components: deployment
> Versions: 0.95
> Environment: Win XP, Tomcat 5.5.7.
> Reporter: Kent Tong
> Assignee: Deepal Jayasinghe
>
> 1) Enable hotupdate by editing axis2.xml.
> 2) Add some code to the service implementation code. For example, from:
> public class SimpleService {
> public OMElement echo(OMElement e) {
> return e;
> }
> }
> To:
> public class SimpleService {
> public OMElement echo(OMElement e) {
> OMAbstractFactory.getOMFactory();
> return e;
> }
> }
> 3) Update the .aar.
> 4) Tomcat will throw an exception when trying to redeploy the service (using reflection). The exception may be a EOFException, ZipException or an ArrayIndexOutOfBoundsException. Two sample stack traces are shown below for the first two exceptions. They're all similar. Suggesting the SchemaGenerator may be reading some outdated class data.
