Hi,
I'm using WTP 1.0M4 with a Tomcat 5 server, but I can't figure out
how to access a data base. As far as I know, if I were using a
standalone Tomcat, I would copy a XML file to
{tomcathome}/conf/Catalina/localhost with something like the following:
<Resource name="jdbc/tienda" type="javax.sql.DataSource"
auth="Container" />
<ResourceParams name="jdbc/tienda">
<parameter>
<name>driverClassName</name>
<value>com.mysql.jdbc.Driver</value>
</parameter>
etc.
Now, I've seen that WTP creates its own Tomcat config in
{workspace}/.metadata/.plugins/org.eclipse.wst.server.core/t mp0, and
this includes de conf/Catalina/localhost folder, with a .xml file
for my webapp. The problem is I can't touch that file because WTP
overwrites it every time my proyect is deployed.
How can I tell WTP to use my own xml file? Is there another way of
doing this?
TIA,
Alex

At the moment, the best way is to create a META-INF/context.xml file in
the WebContent portion of your webapp. The children of the <Context>
element in this file will be included in the <Context> element included
in the tmp0/conf/server.xml file.
The creation of the context file under tmp0/conf/Catalina/localhost is a
"quirk" of Tomcat 5.0. The <Context> in the server.xml takes precedence
over the one under "localhost".
Cheers,
Larry
