Sure. What's the best method to send you the component?
Great! :)
There's a general document on contributing here...
http://activemq.apache.org/camel/contributing.html
but basically, just raise a JIRA and attach whatever code/patches you
like and we can take it from there.

From my testing, it appears that the modification you made to the
JmsComponent starts it's own broker. Is this accurate?
Yes - the broker is started if you use the brokerURL of vm://localhost...
If so, how can
I connect to a standalone broker
If you prefer to connect to a remote broker then use tcp://host:port
instead. To handle auto-reconnection use failover:tcp://host:port
or how can I configure the
JmsComponent to use an ActiveMQ persistence adapter and MySQL data-
source?
You could explicitly configure the broker inside the spring.xml as
well - though you do have to be a little careful that the broker is
started first before the ConnectionFactory (so usually you need to use
the spring xml dependsOn stuff) - as if you are not careful the vm://
transport will auto-create a broker for you first
Currently, I'm using the following Spring configuration to use a
ActiveMQ persistence adapter and a MySQL data-source:
<bean id="broker" class="org.apache.activemq.broker.BrokerService"
init-method="start" destroy-method="stop">
<property name="brokerName" value = "broker"/>
<property name="persistent" value="true"/>
<property name="useJmx" value = "false"/>
<property name="transportConnectorURIs">
<list>
<value>vm://localhost</value>
<value>tcp://localhost:9000</value>
</list>
</property>
<property name="persistenceAdapter" ref="persistenceAdapter"/>
</bean>
<bean id="persistenceAdapter"
class="org.apache.activemq.store.PersistenceAdapterFactoryBean">
<property name="dataSource" ref="mysql-ds"/>
<property name="dataDirectory" value="activemq-data"/>
<property name="journalLogFiles" value="5"/>
</bean>
<bean id="mysql-ds" class="org.apache.commons.dbcp.BasicDataSource"
destroy-method="close">
<property name="driverClassName" value="com.mysql.jdbc.Driver"/>
<property name="url" value="jdbc:mysql://localhost/activemq?
relaxAutoCommit=true"/>
<property name="username" value="root"/>
<property name="password" value=""/>
<property name="poolPreparedStatements" value="true"/>
</bean>
Looks good to me. You could try the Spring 2 XML stuff if you want -
but the above looks fine.
If you prefer to run the broker separately, you could just edit the
activemq.xml that ships with ActiveMQ to configure the MySQL stuff and
use the tcp:// transport to connect to it
