Hello We are using MyEclipse extension to launch a webapp that contains Drools. I would like to debug the WorkingMemory state of this webapp. From reading the user guide I see that suggested method of debugging a drools application is launching the Main class, as my application is a webapp the concept of a Main class does not exists. How should I debug Drools from in this case? Can I maybe remote connect or instruct Drools to simply treat the running JVM as a "Drools Application" when in fact it was launched by Apache Tomcat servlet ? Thank you, Maxim. -- Cheers, Maxim Veksler "Free as in Freedom" - Do u GNU ? _______________________________________________ rules-users mailing list rules-users(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users

Trouble is this is not enough, I want to be able to debug runtime data. I don't mind this "runtime" will be running from my Eclipse instance but I need to be running from within the Servlet. Does someone knows, perhaps one of the devs? How the drools plugin speaks with the WM?

Maybe we could write some interface that would allow to poll it "from outside" - That is from something that is running in a different project. > On Sat, Nov 15, 2008 at 12:57 PM, Maxim Veksler <maxim.veksler(a)gmail.com&gt; > wrote: > >> Hello >> >> We are using MyEclipse extension to launch a webapp that contains Drools. >> I would like to debug the WorkingMemory state of this webapp. >> >> From reading the user guide I see that suggested method of debugging a >> drools application is launching the Main class, as my application is a >> webapp the concept of a Main class does not exists. >> >> How should I debug Drools from in this case? >> Can I maybe remote connect or instruct Drools to simply treat the running >> JVM as a "Drools Application" when in fact it was launched by Apache Tomcat >> servlet ? >> >> >> Thank you, >> Maxim. >> >> -- >> Cheers, >> Maxim Veksler >> >> "Free as in Freedom" - Do u GNU ? >> >> _______________________________________________ >> rules-users mailing list >> rules-users(a)lists.jboss.org >> https://lists.jboss.org/mailman/listinfo/rules-users >> >> > > -- > +1 510 342 5693 > > PO Box 7775 #8750 > San Francisco, California 94120-7775 > > "Warning: following standard input indefinitely is ineffective" > - /bin/tail error message > > "Against logic there is no armor like ignorance." > - Laurence J.
