Talend community forum / Small update to java component creation tutorial needed?

JerryPreissler · 2008-08-29 14:22:53

When trying to follow the java component tutorial at http://talendforge.org/wiki/doku.php?id=doc:component_creation_example_java I'm running into a small issue:

The directory mentioned in the tutorial (plugins/org.talend.designer.core_<version>/components) is not present, the plugin ...designer.core is packaged in a single jar file.

I found the files for the other components in plugins\org.talend.designer.components.localprovider_2.4.1.r16077\components . Can someone in the know confirm that this is the right place to put my new component?

TIA
Jerry

maybe the best solution for your issue is to create a new folder (e.g. /Mycomponent) and to configure talend to use it.
to configure talend you have to specify your folder path into windows>preference>Components after applying you msut restart talend

Thanks for the hint. I did so, but now I'm running in a new problem:

I configured a folder for user components. Whenever I create a new component*, I get an error message during the generation engine initialization. The detail error message is:

Exception during Initialization
No attributes are implemented

and the new message does not appear in the palette.

I experimented a little and did the following:

- stopped TOS
- deleted my component's folder from the user components folder
- copied the tRowGenerator folder from TOS-All-r16077-V2.4.1\plugins\org.talend.designer.components.localprovider_2.4.1.r16077\components to my user components folder
- restarted TOS

I got the same error and the tRowGenerator was not available in the palette anymore. Moving the tRowGenerator folder back to its original place and restarting TOS got me back to normal.

Any ideas how I could get started with component development?

* by creating a subfolder of the user components folder and putting the required files in there

did you copy the content or the folder of the tRowGenerator?

I moved the whole folder.
