[rules-users] Using work items in the Eclipse ruleflow editor

[Jeremy Ary]

For completeness, just a quick note for others who may find themselves here. I spoke with Mike briefly via IRC and the issue appeared to be in getting the files on the classpath correctly. This was ultimately the same thing that I went up against, so iIf you're not sure how to get that wired up, an example follows. I'm certainly far from novice, so any recommendations/improvements are welcome. 


Start a new Drools project (you will see two packages already on the classpath - src/main/java & src/main/rules ) 

Right-click the project name in Package Explorer and select New > Source Folder 

Name the new folder "src/main/resources" in the popup 

Right-click the new source folder and select New > Folder and call it "META-INF" in the popup 

Place your drools.rulebase.conf and custom definitions .conf file into the META-INF folder 

Restart Eclipse and open a .rf file - you should now see your custom work items in place

Mike, 

I ran into a similar issue when I began working with ruleflows a few weeks ago. Some of this may not be necessary and it's certainly not all causal, but this was what I noted when working my issue out: 

1) If you're working in JBoss Dev Studio, it's possible that you have a conflict between the code you added as a runtime and what's already there, so try the process with a fresh install of eclipse 
2) Ensure that any projects you currently have open do not have build/lib/classpath issues (I had the drools projects checked out and open and build errors caused unnecessary complications for me) 
3) Be sure that your project has a META-INF on the classpath and that it's set up correctly 
4) Place your drools.rulebase.conf & custom definitions .conf that it looks for are both in your META-INF under resources (src/main/resources/META-INF) 
5) Once you're sure this much is correct, give Eclipse a restart - my project did not pick up my custom WI's until I restarted 

If you're still having issues, I'll be on the IRC channel for the next 5 hours or so as jary - feel free to reply here or look me up there. 
(well, I'm heading to lunch very soon, so back in around an hour)

I am using Eclipse to build my Drools rulefow file. I am trying to add custom work items, but I cannot seem to get anything (other than Email and Log) to show up in my Work Items palette. 



Does anyone know how to get the existing work items (such as FileFinder or Exec) to show up on the palette in eclipse? 



Eventually I will need to add custom work items to the flow, so this is make-or-break Drools functionality for my team. 



In pursuit of a solution to this I have combed the documentation, this mailing list archive, as well as endless Google results to no avail. Any help would be very valuable! 



Thanks, 

Mike
