How would you like to be the test guinea pig for this (I don't have
Catalina readily available/set up)
Include the encloded class in the org.firebirdsql.jdbc directory. ( I hope
this list allows attachments!)
Include something like this in catalina's server.xml
<Resource name="java:/firebirdDS" auth="Container"
type="org.firebirdsql.jdbc.FBWrappingDataSource"/>
<ResourceParams name="java:/firebirdDS">
<parameter>
<name>factory</name>
<value>org.firebirdsql.jdbc.FBDataSourceObjectFactory</value>
</parameter>
<parameter>
<name>DatabaseName</name>
<value>localhost/3050:/usr/.....(url)</value>
</parameter>
<parameter>
<name>User</name>
<value>sysdba</value>
</parameter>
<parameter>
<name>Password/name>
<value>masterkey</value>
</parameter>
<parameter>
<name>MinSize</name>
<value>1</value>
</parameter>
<parameter>
<name>MaxSize</name>
<value>10</value>
</parameter>
<parameter>
<name>BlockingTimeout</name>
<value>5000</value>
</parameter>
<parameter>
<name>IdleTimeoutMinutes</name>
<value>30</value>
</parameter>
</ResourceParams>
I made it set pooling always true: if this seems like a bad idea we could
make it configurable.
Let me know if it works ;-)
