If you are using 5.2.0-SNAPSHOT in both of your applications, this shouldn't be happening. Please double check it.<div>As a workaround, you could get rule's sources from Guvnor instead of the binary package.</div><div>

Hi,<br>
<br>
I had previously posted to drools-users. Maybe wrong place for it. I am an<br>
absolute new user. Excited and Very keen to have this working and for any<br>
feedback to help me progress.<br>
<br>
I'm using the 5.2.0-SNAPSHOT binaries for making use of the new auth<br>
attributes in the kagent:resource tag.<br>
<br>
I'm attempting to get PKG out of Guvnor. Using the following<br>
droolsservice.xml config<br>

As far as i can tell the ChangeSet.xml is coming down. The PKG accessed.<br>
Though then...<br>

The issue lies behind 'stream.readObject();' from JavaDialectRuntimeData<br>
around line 167<br>
<br>
// Return the object stored as a byte[]<br>
byte[] bytes = (byte[]) stream.readObject();<br>
if ( signed ) {<br>
checkSignature( stream,<br>
helper,<br>
bytes,<br>
pubKeyAlias );<br>
}<br>
<br>
guvnor and my sample app are both running 5.2.0-SNAPSHOT. Really appreciate<br>
any advice. Is it falling over an a parse of the binary and some<br>
disagreement on contents of payload?<br>
<br>
Thanks<br>
