Hi,
I'm using the 5.2.0-SNAPSHOT binaries for making use of the new auth
attributes in the kagent:resource tag.
I'm attempting to get PKG out of Guvnor. Using the following
droolsservice.xml config
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:drools="http://drools.org/schema/drools-spring"
xsi:schemaLocation="http://www.springframework.org/schema/beans

http://camel.apache.org/schema/spring
http://camel.apache.org/schema/spring/camel-spring.xsd" >
<drools:kagent kbase="knowledgeBase" id="kagent" new-instance="false">
<drools:resources>
<drools:resource type="CHANGE_SET"
basic-authentication="enabled" username="admin" password=""
source="http://localhost:8080/drools-guvnor.war/org.drools.guvnor.Guvnor/package/TicketImportPackage/LATEST/ChangeSet.xml"
/>
</drools:resources>
</drools:kagent>
</beans>
As far as i can tell the ChangeSet.xml is coming down. The PKG accessed.
Though then...

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