congiguration problem

Hi
when I configure the postgresql with ofbiz with following code.and i put the jar in framework/entity/lib/jdbc

<delegator name="default" entity-model-reader="main" entity-group-reader="main" entity-eca-reader="main"
distributed-cache-clear-enabled="false">
<group-map group-name="org.ofbiz" datasource-name="localpostgres"/>
<group-map group-name="org.ofbiz.olap" datasource-name="localpostgres"/>
</delegator>
<delegator name="default-no-eca" entity-model-reader="main" entity-group-reader="main" entity-eca-reader="main"
entity-eca-enabled="false" distributed-cache-clear-enabled="false">
<group-map group-name="org.ofbiz" datasource-name="localpostgres"/>
<group-map group-name="org.ofbiz.olap" datasource-name="localpostgres"/>
</delegator>

<!-- be sure that your default delegator (or the one you use) uses
the same datasource for test. You must run "ant run-install" before
running "ant run-tests" -->
<delegator name="test" entity-model-reader="main" entity-group-reader="main" entity-eca-reader="main">
<group-map group-name="org.ofbiz" datasource-name="localpostgres"/>
<group-map group-name="org.ofbiz.olap" datasource-name="localpostgres"/>
</delegator>
<delegator name="other" entity-model-reader="main" entity-group-reader="main" entity-eca-reader="main">
<group-map group-name="org.ofbiz" datasource-name="localpostgres"/>
</delegator>

After it when i run ant run-install, it give the following error.
