Hi,
I wrote a small application using eclipse equinox, that accesses a database
using eclipselink JPA and exposes some services using apache CXF. I manged
to get this to work using the embedded jetty. In this scenario, the
standalone application gets some command-line parameters specifying to which
database connect and under what port to expose the http-server. This is
fine, so I moved a step further and tried to deploy the same code using the
servletbridge into some servlet-containers. After some troubles I managed to
get this work for tomcat6 and Oracle 10g app-server (10.1.2).
For passing the parameters specifying my database, I used the launch.ini in
the servletbridge directory to set some environment-variables. But this
solution has one mayor drawback: To adapt the jdbc-url I have to edit the
launch.ini, make a new .war and deploy this .war on my app-server.
Is there a way to do this more conveniently? I'm new to application servers,
here is what I tried so far:
But how do I get the jdbc-connection from within my eclipse-application? I'm
doing the following to get the httpService in my Activator:
ServiceReference reference = context.getServiceReference(
HttpService.class.getName());
HttpService httpService = null;
if ( reference != null)
httpService = ( HttpService) context.getService( reference);
To get the db-connection I tried the following code from the tomcat-6
documentation (
http://tomcat.apache.org/tomcat-6.0-doc/jndi-datasource-examples-howto.html
):
try {
javax.naming.Context initContext = new
javax.naming.InitialContext();
javax.naming.Context envContext =
(javax.naming.Context)initContext.lookup("java:/comp/env");
javax.sql.DataSource ds =
(javax.sql.DataSource)envContext.lookup("jdbc/myoracle");
java.sql.Connection conn = ds.getConnection();
} catch ( SQLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch ( NamingException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
But this didn't work. Tomcat6 complained about
"java.lang.ClassNotFoundException:
org.apache.naming.java.javaURLContextFactory" and OC4J reported it could not
find the java:/comp/env context.
Any hints on how to solve this?
Best regards
