[rules-users] Error using change-set

Hi, I am trying to use a change-set file to load my DSL and DSLR resources, but I am not able to get it working. My first attempt was based on the snippet I found here: http://downloads.jboss.com/drools/docs/5.0.1.26597.FINAL/drools-expert/ht... <?xml version="1.0" encoding="UTF-8"?<change-set xmlns='http://drools.org/drools-5.0/change-set' xmlns:xs='http://www.w3.org/2001/XMLSchema-instance' xs:schemaLocation='http://drools.org/drools-5.0/change-set.xsd' <add <resource source='file:classification.dsl' type='DSL' / <resource source='file:classification.drl' type='DSLR' / </add</change-set but I received the following error: (null: 4, 78): SchemaLocation: schemaLocation value = ' http://drools.org/drools-5.0/change-set.xsd' must have even number of URI's. (null: 4, 78): cvc-elt.1: Cannot find the declaration of element 'change-set'. Then, I found the following old post in the mailing list: http://drools-java-rules-engine.46999.n3.nabble.com/changset-xml-error-wh... where it was suggested to "Just replace *xs:schemaLocation='**http://drools.org/drools-5.0/change-set. xsd* <http://drools.org/drools-5.0/change-set.xsd>*'* by *xs:schemaLocation ='http://drools.org/drools-5.0/change-set drools-change-set-5.0.xsd'*" So I changed my file to: <?xml version="1.0" encoding="UTF-8"?<change-set xmlns='http://drools.org/drools-5.0/change-set' xmlns:xs='http://www.w3.org/2001/XMLSchema-instance' xs:schemaLocation='http://drools.org/drools-5.0/change-setdrools-chan... <add <resource source='file:classification.dsl' type='DSL' / <resource source='file:classification.dslr' type='DSLR' / </add</change-set but now I receive the following errors: (null: 4, 100): schema_reference.4: Failed to read schema document 'drools-change-set-5.0.xsd', because 1) could not find the document; 2) the document could not be read; 3) the root element of the document is not <xsd:schema>.

What am I missing? Thanks. Raf
