Michael Neale commented on JBRULES-1028:
----------------------------------------

For some more details on how to do this: 

BRXMLPersistence.getInstance().unmarshal -- this gives a RuleModel from the XML
BRDRLPersistence.getinstance.marshal - this takes the RuleModel and dumps out the DRL
The name in the RuleModel SHOULD be the same as the file that it came from. If its not, it would be best to set it to the same as the file (minus the extension).

The DRL can then be added to the PackageBuilder - of course this will also need the imports added beforehand etc (and the package name). 

In the BRMS this is all done with ContentpackageAssembler. In the IDE, the Guided editor will create some .package file that contains the imports etc... thats how the editor knows what to work with. 

This code will need to cater for that. So we can either make people use package builder plus the above, OR we can enhance package builder, OR we create an ant task to automate it all.

If we have an ant task, it needs to cater for ALL asset types (like the BRMS does) - that includes decision tables, .dslr rules (loading up the dsl files) and ruleflows, adding it all to a package. Thus the ant task can be pointed at a folder and it will do the rest (of course it needs a classpath).

> The new feature in Jboss rule 4.0, the " New guided drl editor". 
> This feature which works similar to the drools-jbrms in the Eclipse plugin.
> I am able to create the necessatry rules, but as the edited rules exist in "rule.brxml" and in "rule.package". 
> How to Import this ".brxml" and ".package" into the package builder in order to get the package into the Rulebase and get working?
> I tried using the XmlPackageReader.read(reader) and then tried to build through the PackageBuilder . In other case also used the adddrlfomxml().
> It failed in both the case stating it as the
