Re: [rules-users] Unable to resolve class error , drools 5.5 in concurrent execution. JSR94Support and Spring
This is the method which throws Exception during concurrency. Highlighted
Line number throws the exception
ClassName : ClassFieldAccessorCache
public Class getClass(String className) {
try
{ return this.classLoader.loadClass( className ); // Exception happens here.
And This happens only during multithreading or concurrent calls. }
catch ( ClassNotFoundException e )
{ throw new RuntimeDroolsException( "Unable to resolve class '" + className
+ "'" ); }
}

Re: [rules-users] Unable to resolve class error , drools 5.5 in concurrent execution. JSR94Support and Spring
5.5 was not thread-safe and some of these concurrency issues have been fixed in later versions. Could you try 5.6 or 6.x?

Add the field to the pattern (as you have done for "fieldName") and then enter a variable name for the field (you might need to add a "list != null" constraint, I can't remember) On 2 July 2014 12:18, Rajeswari wrote: > Thanks > How can I do this in Business Rule Editor. > I should be able to use the editor instead of free form DRL > > > > -- > View this message in context: > http://drools.46999.n3.nabble.com/Usage-of-java-util-List-in-Drools-Guvnor-5-5-0-tp4030217p4030224.html > Sent from the Drools: User forum mailing list archive at Nabble.com. > ___ > rules-users mailing list > rules-users@lists.jboss.org > https://lists.jboss.org/mailman/listinfo/rules-users > ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users

So your FormatConfig object contains a list that you need access to? rule "MyFormat" dialect "mvel" when config : FormatConfig( fieldName == "AMOUNT", $l : listField ) then $l.doWhatEverYouWant(); config.setRegEx( "123" ); retract( config ); end On 2 July 2014 12:05, Rajeswari wrote: > Hi, > I need to modify the List field in my Config object. > > > > -- > View this message in context: > http://drools.46999.n3.nabble.com/Usage-of-java-util-List-in-Drools-Guvnor-5-5-0-tp4030217p4030222.html > Sent from the Drools: User forum mailing list archive at Nabble.com. > ___ > rules-users mailing list > rules-users@lists.jboss.org > https://lists.jboss.org/mailman/listinfo/rules-users > ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users

Re: [rules-users] How to migrate data from Guvnor 5.1.1 to 5.3.3.Final version.
The only solution that could work is to export your repository from 5.1.1 and import into 5.3.3. You'll loose all history though.

[rules-users] How to migrate data from Guvnor 5.1.1 to 5.3.3.Final version.
Hi , I need information on how to migrate existing repository from Guvnor 5.1.1 to 5.3.3.Final version. Currently i am using Guvnor 5.1.1 version and data is stored in Oracle database. I am moving to Guvnor 5.3.3.Final version. I would like to migrate the existing data from Guvnor 5.1.1 to 5.3.3.Final instance. One way i see is export from Guvnor 5.1.1 and import the exported xml in Guvnor 5.3.3.Final instance. Is there any other way to migrate the data?
