Hi! I have written this for those of you who are interested in UIMA-Stanbol integration: http://blog.iks-project.eu/running-uima-engines-in-stanbol-using-the-same-jvm/
The bottom line: If you don't want to use UIMA trough rest (e.g. you cannot accept the overhead REST), you can create your customized bundle following the instructions described in this blog post. Cheers, Mihály
