Hi Ignacio,  I have placed it in the same location as my impl class.  It it
named <classname>.componentType.

Re: [jira] Created: (TUSCANY-967) NPE when loading componentType side file with callbackInterface attribute defined

Posted by Ignacio Silva-Lepe <is...@gmail.com>.

>From the stack trace, your componentType side file is not being
found and the component type is being loaded by introspection.
Where are you placing your side file? The component type loader
uses the following to find the side file:

 URL resource = implClass.
               getResource(JavaIntrospectionHelper.
                        getBaseName(implClass) + ".componentType");

where implClass is a java.lang.Class that represents the
implementation class of your component.
When it does not find it (ie, resource is null), it tries to load by
introspection rather than from the side file.

[jira] Commented: (TUSCANY-967) NPE when loading componentType side file with callbackInterface attribute defined

Posted by "Lou Amodeo (JIRA)" <tu...@ws.apache.org>.

    [ https://issues.apache.org/jira/browse/TUSCANY-967?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12464315 ] 

Lou Amodeo commented on TUSCANY-967:
------------------------------------

I am still seeing this.   When you unzipped the test case did you remove the target directory before running the test case?  The zipped up test case has a target folder that contains a hand copied componentType file.  Can you please verify?

[jira] Commented: (TUSCANY-967) NPE when loading componentType side file with callbackInterface attribute defined

Posted by "Lou Amodeo (JIRA)" <tu...@ws.apache.org>.

Lou Amodeo commented on TUSCANY-967:
------------------------------------

I see the problem.  I am using the integration test environment (itest) and it looks like resource files are not being copied to the /target directory along with the class files.   I guess this JIRA should be redirected to the itest component.  I dont know how this is done though.

[jira] Resolved: (TUSCANY-967) NPE when loading componentType side file with callbackInterface attribute defined

Posted by "Raymond Feng (JIRA)" <tu...@ws.apache.org>.

     [ https://issues.apache.org/jira/browse/TUSCANY-967?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Raymond Feng resolved TUSCANY-967.
----------------------------------

    Resolution: Invalid

I cannot reproduce this issue. The componentType file is correctly located. Then I run into the issue reported by TUSCANY-1045.

[jira] Commented: (TUSCANY-967) NPE when loading componentType side file with callbackInterface attribute defined

Posted by "Raymond Feng (JIRA)" <tu...@ws.apache.org>.

    [ https://issues.apache.org/jira/browse/TUSCANY-967?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12464328 ] 

Raymond Feng commented on TUSCANY-967:
--------------------------------------

Sorry, I didn't run "mvn clean". But the good news is that I found the problem in the test case, any resource files should be packaged in "src/main/resources" or "src/test/resources". This is a maven setting. After fixing that the componentType file is copied.
