Java API change in MT 4.1.2?

jfincke

I just upgraded to 4.1.2 and now my custom processor is throwing this error. It's based on skeleton code I downloaded from the support site for Java plugins. Here's the relevant bit of the stacktrace:

java.lang.NoClassDefFoundError: com/interwoven/icm/mtparser/Attribute
at com.interwoven.metatagger.plugin.MTRunPlugin.main(MTRunPlugin.java:29)

The wierd thing is that line 29 doesn't reference Attribute, it only references MTPluginUtils, which is in the same jar file.

Anyway, here's the rest of the stack trace:

Root cause:

With 4.1.2 the iw-mt.jar which was shipping for previous versions of MT was re-organized into different jars:

(1) iwmt-api.jar (2) iwmt-ciadmin.jar (3) iwmt-civiewer.jar (4) iwmt-clt.jar (5) iwmt-studio.jar

can you please check that you have the iwmt-api.jar in your classpath
