Problem with Guvnor using Rest API
by Demian Calcaprina
Hey Guys.
I am using guvnor 5.5.0.Final.
I am accesing to from another app using the REST API. I am currently having
a problem. I create a new package, sending a post to guvnor/rest/packages/,
sending it an xml version of PackageMetadata. Then, I create assets (drl
files), by sending a post to guvnor/rest/packages/" + packageName +
"/asset, with the drl contents. This works fine. The problem in with
package building. I read somewhere that it is automatically built when you
create a new asset or update one. But just after creating the package, I go
to the package url, the one I configure in the changeset,
localhost:8080/guvnor/org.drools.guvnor.Guvnor/package/mypackage/LATEST,
and I get a NPE,
java.lang.NullPointerException
java.io.OutputStream.write(OutputStream.java:75)
org.drools.guvnor.server.files.FileManagerService.loadBinaryPackage(FileManagerService.java:201)

org.jboss.solder.servlet.event.ServletEventBridgeFilter.doFilter(ServletEventBridgeFilter.java:74)
If I build the package manually, I am able to get the PKG there. I am
making something wrong? Is there a way to make it build the package
from REST?
Thanks!

Does someone know how guvnor manages JCR sessions, and/or if there is a
potential bug somewhere?
Thanks!

Guvnor repository backward compatible?
by Sean Su
While evaluating and building rules in using Guvnor 5.5, we have noticed
that there will be some major changes in 6.0. We have some concerns that
the repository (rules) built using 5.5 may not be accessible by Gunvor 6.0.
Does anyone know anything about this? Do we have document about 6.0? It
seems the document in the 6.0 beta download has the old content.
Also what is the estimated release date for 6.0?
Thanks
