[jira] Created: (TUSCANY-1867) @OneWay with String return type
causes NullPointerException
@OneWay with String return type causes NullPointerException
-----------------------------------------------------------
Key: TUSCANY-1867
URL: https://issues.apache.org/jira/browse/TUSCANY-1867
Project: Tuscany
Issue Type: Bug
Components: Java SCA Axis Binding Extension
Affects Versions: Java-SCA-1.0
Environment: Windows XP
Reporter: Simon Nash
Fix For: Java-SCA-Next
I tried using @OneWay on a method with a String return type and I got a NullPointerException, like this:
Exception in thread "Axis2 Task" java.lang.NullPointerException
at org.apache.axis2.description.OutInAxisOperationClient$NonBlockingInvocationWorker.run(OutInAxisOperation.java:444)
at edu.emory.mathcs.backport.java.util.concurrent.ThreadPoolExecutor$Worker.runTask(ThreadPoolExecutor.java:665)
at edu.emory.mathcs.backport.java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:690)
at java.lang.Thread.run(Thread.java:595)
We should produce a better exception to tell the user what he/she has done wrong.

Hi Vamsi,
FYI... Fixes for SCANodeManagerService.destroyNode() is also available from TUSCANY-2252. Since you have also included a fix for @OneWay annotation exception in your patch TUSCANY-1867-2.patch. We could probably ignore the patch for TUSCANY-2252, and apply the ones available in this JIRA.

[jira] Reopened: (TUSCANY-1867) @OneWay with String return type
causes NullPointerException
Posted by "Vamsavardhana Reddy (JIRA)" <tu...@ws.apache.org>.
[ https://issues.apache.org/jira/browse/TUSCANY-1867?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Vamsavardhana Reddy reopened TUSCANY-1867:
------------------------------------------
r656190 is causing build failures in samples\callback-ws-service because @OneWay annotation is present on org.apache.tuscany.sca.node.management.SCANodeManagerService.destroyNode(). And the message in the exception is not really helpful if it does not tell what is the problematic method carrying the @OneWay annotation.

[jira] Commented: (TUSCANY-1867) @OneWay with String return type
causes NullPointerException
Posted by "Ramkumar Ramalingam (JIRA)" <tu...@ws.apache.org>.
[ https://issues.apache.org/jira/browse/TUSCANY-1867?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12589541#action_12589541 ]
Ramkumar Ramalingam commented on TUSCANY-1867:
----------------------------------------------
This JIRA talks about producing better exception message for those methods with @OneWay annotations, when these method does not have "void" return type. The best place to throw this exception would be in the org.apache.tuscany.sca.interfacedef.java.impl.JavaInterfaceIntrospectorImpl code as shown below, instead of allowing them to crop-up in the axis2 code.
boolean nonBlocking = method.isAnnotationPresent(OneWay.class);
if (nonBlocking) {
if (!(returnType == void.class)) {
throw new InvalidOperationException(
"Method should return 'void' when declared with an @OneWay annotation.",
method);
}
if (!(faultTypes.length == 0)) {
throw new InvalidOperationException(
"Method should not declare exceptions with an @OneWay annotation.",
method);
}
}
I'll attach a patch with this fix.
