I've been trying to add the legacydb delegator instructed in
https://cwiki.apache.org/confluence/display/OFBIZ/Handling+of+External+data
but keep getting a nullPointerException error when
this.getModelFieldTypeReader(entity) is called at line 539 of
GenericDelegator.java. The exeption occurs for the fields that are
supposed to be used for the legacydb delegator. The problem seems to be
that the default delegator knows about the entities that are supposed to
be handled by the legacydb delegator.
Can anyone tell me what I might be missing?
I created this delegator in entityengine.xml:
<delegator name="legacydb" entity-model-reader="main"
entity-group-reader="main" entity-eca-reader="main"
distributed-cache-clear-enabled="false">
<group-map group-name="org.legacydb" datasource-name="localmssql"/>
</delegator>
I also created the entitygroup_olap.xml file with records for each
entity as follows:
<entity-group group="org.legacydb" entity="ApprovedsuppliersV2" />
I have these entity resources in the
hot-deploy/legacydb/ofbiz-component.xml file:
<entity-resource type="model" reader-name="main" loader="main"
location="entitydef/entitymodel.xml"/>
<entity-resource type="group" reader-name="main" loader="main"
location="entitydef/entitygroup_olap.xml"/>
