Subject How do I configure Index Rules when using OCM
Date Wed, 28 Jan 2009 06:20:46 GMT

I am trying to configure the index rules for jackrabbit where I am using OCM to persist my

My understanding so far is that JackRabbit would index everything unless we specify specific
rules as part of index configuration. I need specific indexes to improve the start time for
a repository.

Once I define the index rules I am unable to retrieve the data.

I am attaching code snippets for index rule, jcrmapping & extracted log statements from
the query execution part.

Let me know if I am missing something or is there a different way of defining index when using
OCM? Is there a separate test case for the same?

In case any additional information is needed related to this then let me know.

Path for storing all the objects is "/rules/metadata"

Index rule configuration for properties is as follows:
  <index-rule nodeType="nt:unstructured">
  <index-rule nodeType="nt:unstructured">
  <index-rule nodeType="nt:unstructured">
  <index-rule nodeType="nt:unstructured">

Jcr mapping is as follows:
<class-descriptor className="com.test.TestVO" jcrType="nt:unstructured" >
          <field-descriptor fieldName="id" jcrName="id" id="true" />
          <field-descriptor fieldName="name"  jcrName="name"  />
          <field-descriptor fieldName="path"  path="true" />
<field-descriptor fieldName="prop1"  jcrName="prop1"  />
<field-descriptor fieldName="prop2"  jcrName="prop2"  />
<field-descriptor fieldName="prop3"  jcrName="prop3"  />
<field-descriptor fieldName="prop4"  jcrName="prop4"  />
