I right-clicked on the drools-guvnor project, scrolled down to PyDev, and selected ‘Set as PyDev project’.  That seems to fix the ‘no python nature’ error. I’m scratching my head a little as if there’s any Python here it’s not obvious. Next error is The project: drools-repository, which is referenced by the classpath, does not exist. I tried importing that into Eclipse.  Now it wants drools-templates, drools-decisiontables.  I import them. Now it says Exception in thread "main" java.lang.NoClassDefFoundError: com/google/gwt/dev/GWTShell Hmm, does it just need this in my project build path? I take a minute to set up my GWT_DEV classpath correctly.  No, that didn’t fix it.  gwt-dev-linux.jar is in fact the home of the GWTShell class. This JAR file is not present in the project Java Build Path Libraries (all the M2_REPO entries are there but nothing referring to GWT_HOME or GWT_DEV) so I try adding it. Exception in thread "main" java.lang.UnsatisfiedLinkError: /home/lmulcahy/java/gwt-linux-1.5.2/libswt-pi-gtk-3235.so: /home/lmulcahy/java/gwt-linux-1.5.2/libswt-pi-gtk-3235.so: wrong ELF class: ELFCLASS32 (Possible cause: architecture word width mismatch) I go in Run Configurations and select a 32 bit JRE instead of the default 64 bit. Yay!  It comes up. ________________________________ From: rules-dev-bounces(a)lists.jboss.org [mailto:rules-dev-bounces@lists.jboss.org] On Behalf Of Mulcahy, Lawrence Sent: Monday, October 12, 2009 2:51 PM To: 'Rules Dev List' Subject: Re: [rules-dev] Guvnor in hosted mode My search for a file mentioning mvel2-2.0.9-SNAPSHOT.jar failed because of a typo in the search string.  It’s in drools-guvnor/Guvnor.launch.

Looking in the source tree, I found this instead: drools-guvnor/target/drools-guvnor/WEB-INF/lib/mvel2-2.0.10.jar (I’m working with drools-5.0-src.zip downloaded from http://www.jboss.org/drools/downloads.html) Can anyone tell me where this is configured?  File search in Eclipse didn’t turn it up. ________________________________ From: rules-dev-bounces(a)lists.jboss.org [mailto:rules-dev-bounces@lists.jboss.org] On Behalf Of Mulcahy, Lawrence Sent: Monday, October 12, 2009 11:06 AM To: 'Rules Dev List' Subject: Re: [rules-dev] Guvnor in hosted mode OK, there is some documentation at http://www.jboss.org/community/wiki/RulesRepositoryBuildInstructions that seems to touch on this… I need to configure the location of GWT in build.properties, and apparently the version that was used is 1.5.2 (that’s what’s in my build.properties now). ________________________________ From: rules-dev-bounces(a)lists.jboss.org [mailto:rules-dev-bounces@lists.jboss.org] On Behalf Of Mulcahy, Lawrence Sent: Monday, October 12, 2009 10:53 AM To: 'Rules Dev List' Subject: Re: [rules-dev] Guvnor in hosted mode The Ant target gwt-shell in drools-guvnor/build.xml sounded promising, but when I tried to run it, it got this error Could not load definitions from resource de/samaflost/gwttasks/antlib.xml. It could not be found. That is coming from this taskdef:             <taskdef uri="antlib:de.samaflost.gwttasks"                           resource="de/samaflost/gwttasks/antlib.xml"                           classpath="../lib/gwttasks.jar"/> Relative to drools-guvnor, there is no ../lib. I searched for gwttasks.jar in the Drools source and in the GWT (1.7.1) distribution but didn’t find it. Jboss.org is having another bad web day.  There’s probably something about this in the wiki or documentation but it’s all inaccessible right now. ________________________________ From: rules-dev-bounces(a)lists.jboss.org [mailto:rules-dev-bounces@lists.jboss.org] On Behalf Of Mulcahy, Lawrence Sent: Monday, October 12, 2009 8:47 AM To: 'Rules Dev List' Subject: Re: [rules-dev] Guvnor in hosted mode Thanks Michael.  How can I do this?  Or is it documented somewhere? If there’s a ‘how to work with the Drools code’ document somewhere that would be really cool.  We are thinking about doing a custom rule editor for an internal application. ________________________________ From: rules-dev-bounces(a)lists.jboss.org [mailto:rules-dev-bounces@lists.jboss.org] On Behalf Of Michael Neale Sent: Saturday, October 10, 2009 5:17 AM To: Rules Dev List Cc: rules-dev(a)lists.jboss.org Subject: Re: [rules-dev] Guvnor in hosted mode It is the right list - and yes it can. All development happens in gwt hosted mode. I put in some special code to let it work with hosted mode tomcat etc for quick turnaround. If you use eclipse, you need to keep the launch config deps up to date - with idea it is automatic. Sent from my phone.
