Pentaho JNDI source name as parameter (Multi-Tennant)

Question

I have googled this for the last half an hour, and found hits for pentaho parameters etc but nothing that appears to ask or answer this question.

I have a set of reports

Answer 1

OK, I have found a better solution using the little documented multi-tennant feature.

1) Stop Pentaho

2) Modify ( pentaho-solutions/system/pentahoObjects.spring.xml )

<!-- Original Code
 <bean id="IDBDatasourceService" class="org.pentaho.platform.engine.services.connection.datasource.dbcp.DynamicallyPooledOrJndiDatasourceService" scope="singleton">
   <property name="pooledDatasourceService" ref="pooledOrJndiDatasourceService" />
   <property name="nonPooledDatasourceService" ref="nonPooledOrJndiDatasourceService" />
 </bean>
 -->

 <!--Begin Tenant -->
   <bean id="IDBDatasourceService" class="org.pentaho.platform.engine.services.connection.datasource.dbcp.tenantaware.TenantAwareLoginParsingDatasourceService"
   scope="singleton">
     <property name="requireTenantId" value="false" />
     <property name="datasourceNameFormat" value="{1}-{0}" />
     <property name="tenantSeparator" value="@" />
     <property name="tenantOnLeft" value="false" />
   </bean>
 <!-- End Tenant -->

3) Add Suffix to Data Sources ( biserver-ce/tomcat/webapps/pentaho/META-INF/context.xml )

<Resource
  name="jdbc/MYDBSRC-xxx"
  auth="Container"
  type="javax.sql.DataSource"
  factory="org.apache.commons.dbcp.BasicDataSourceFactory"
  maxActive="20"
  maxIdle="5"
  maxWait="10000"
  username="XXXX"
  password="XXXX"
  driverClassName="net.sourceforge.jtds.jdbc.Driver"
  url="jdbc:jtds:sqlserver://192.168.42.0:1433;DatabaseName=SOMEDB"
/>

<Resource
  name="jdbc/MYDBSRC-aaa"
  auth="Container"
  type="javax.sql.DataSource"
  factory="org.apache.commons.dbcp.BasicDataSourceFactory"
  maxActive="20"
  maxIdle="5"
  maxWait="10000"
  username="XXXX"
  password="XXXX"
  driverClassName="net.sourceforge.jtds.jdbc.Driver"
  url="jdbc:jtds:sqlserver://192.168.42.0:1433;DatabaseName=AOTHERDB"
/>

4) Delete /tomcat/conf/Catalina/localhost/pentaho.xml

5) Restart Pentaho, create a user someone@xxx etc etc

6) Create a report using the JNDI Name "MYDBSRC"

7) Login as someone@xxx and you will get a different report / datasource than either logging in as user, or user@aaa

Tadah !!
