Re: How to change the ActiveMQ DataSource?

Wed, 21 Nov 2007 12:16:30 -0800 

Hi
I suspect a bug in the local attribute manager reference override. Note that the 3 (or more?) gbeans it found all have different j2eeType which makes me think there's something missing from the reference pattern setup in LAM. Fixing the bug would be great :-), opening a jira next best, and meanwhile deploying your own broker plan should work. 

Ok, ok... I will try to fix it ;-) But how to specify the reference?
I think an easy way would be to add a 'generic' definition like this:

--- 8< --- (start)

<reference name="dataSource">
     <pattern>
       <name>MyDatasource</name>
       <j2eeType>Something</j2eeType>
       <someAtt>foo</someAtt>
     </pattern>
</reference>

--- 8< --- (end)


Currently only the elements: groupId, artifactId, version, type, module 
and name are allowed. There are no other 'name parts' available.


Other definition syntax might be:

--- 8< --- (start)

<reference name="dataSource">
     <pattern>
       <nameMap>
          <name>MyDatasource</name>
          <j2eeType>Something</j2eeType>
          <someAtt>foo</someAtt>
       </nameMap>
     </pattern>
</reference>

--- 8< --- (end)

This would break existing configs :-(

If you want to shift the entire server to using mysql you can put a 
couple lines in artifact_aliases.properties to switch system-database to 
your database.  As long as your datasources are named the same as in 
system-database everything should work.

Hi


I'm trying to reconfigure the DataSource used by the ActiveMQ broker 
service (from derby to mysql). For that I created a DataSource config 
(CAR) with a simple plan pointing to my MySQL Database. The 
configuration for the database works fine. I can access the Connection 
Pool and execute SQL statements... ;-)


Here is my db plan file:

--- 8< --- plan.xml --- (start)

<connector 
xmlns="http://geronimo.apache.org/xml/ns/j2ee/connector-${geronimoSchemaVersion}";> 


    <resourceadapter>
        <outbound-resourceadapter>
            <connection-definition>

                
<connectionfactory-interface>javax.sql.DataSource</connectionfactory-interface> 


                <connectiondefinition-instance>
                    <name>MyDatasource</name>

                    <config-property-setting 
name="Driver">com.mysql.jdbc.Driver</config-property-setting>
                    <config-property-setting 
name="ConnectionURL">jdbc:mysql://localhost:3306/ode</config-property-setting> 

                    <config-property-setting 
name="UserName">root</config-property-setting>

              <connectionmanager>
                <local-transaction/>
                        <single-pool>
                            <max-size>100</max-size>

                            
<blocking-timeout-milliseconds>5000</blocking-timeout-milliseconds>

                            <select-one-assume-match/>
                        </single-pool>
                    </connectionmanager>
                </connectiondefinition-instance>
            </connection-definition>
        </outbound-resourceadapter>
    </resourceadapter>
</connector>
--- 8< --- plan.xml --- (end)


I have also added a dependency to my database CAR from the ActiveMQ 
config and "recompiled" the configuration.



But when I specify the "database reference" within the 
ActiveMQBrokerGBean (config.xml) I'm getting the following exception: 
"More than one match to referencePatterns in parent configurations"


--- 8< --- config.xml --- (start)

    <gbean name="ActiveMQ">

                <pattern>
                    <name>MyDatasource</name>
                </pattern>
        </reference>
    ...

--- 8< --- config.xml --- (end)

How do I have to specify this reference? Is this possible to do it 
that way??

Or do I have to use an (external) activemq.xml file?

Thanks


Kristian
