For the astute JBoss BPM fan it will not have escaped you that the community has been hard at work putting together a lot of new features for the upcoming JBoss BPM Suite 6.2 release.
With the early internal Red Hat releases being made available, some of the testing I do around updating the array of demo projects we have has revealed a subtle change. It got me to thinking that I could point out a few of these tips and tricks to your as the product approaches delivery to the public.
The RestAPI is a much used feature of JBoss BPM Suite and one if the first changes you will bump into is that the user making use of the interface needs to have a new role added to their privileges.
If you use a previous client application that was connecting to JBoss BPM Suite, the user did not need a specific role. For example our Generic Loan demo project contains a client application to pre-load our process.
The results of this call in JBoss BPM Suite 6.2 without the new role would be:
For more details you can explore this in the Generic Loan demo project as found in JBoss Demo Central.

The role needs to be added to the file application-roles.properties and put into the standalone server directory, jboss-eap-6.4/standalone/configuration/application-roles.properties. For example, in our project you will find it looks like this:erics=analyst,admin,manager,user,loanOfficer,kie-server,rest-all
Now when you run the client application to pre-load your processes you will see:
$ java -jar support/jboss-mortgage-demo-client.jar erics bpmsuite1!
Started process instances successfully!
