Test 1 will not work because the xs:schemaLocation does not point to valid location for the schema.

You can work around this by configuring an XML Catalog in your IDE so it treats "drools-change-set-5.0.xsd" as an alias.

Checkout the widely available xs:schemaLocation documentation for details of its syntax.


Test 2 *should* be OK. The referenced schema does exist and is valid.

guvnor-examples uses the exact same and works well (or at least for me!)

Can you provide a self-contained unit test to replicate the issue?

fine no issues but i got the following warning messages...

*Question: how to get rid of this? I completely google the web including
user forum no answer.If it is available in the forum, my apologies for
missing that info...some one could forward me to that info location.*

<resource source='classpath:dir1/dir2/filename.drl' type='DRL' />
</add>
</change-set>


when i use the above changeset (grepcode drools-compiler 5.2.1
Final)...after 1 minute it gives the following error message and the thread
is open for ever...nothing happen.
