Hello all,
I use Taverna 1.7.2 and specifically the bootstrap jar 1.7.2.1. I want
to run it from my web application (war) launched by jetty-runner.jar,
but I get a conflict when I try to execute a workflow. I have my own
log4j jar embedded into my webapp with my config, and it seems that
Bootstrap get its own too, which lead to a jar hell and make my app
shuting down, as you can see below when I try to execute given example
workflow
"file:/taverna/taverna-1.7.2/examples/fetch_today_s_xkcd_comic.xml" with
Boostrap.main(workflowArgs):

Does anyone of you know how to avoid such a jar hell ? Is it possible to
disable log for Taverna in order Bootstrap runs correctly ?
Running bootstrap jar from command line work correctly.
Any help would be greatly appreciated.
Raphael.
