(SJAS9) Reading a context param in a web service

Question

Platform - SJAS9, NB5.5
I am trying to add a web service to a small web project and I need database access for it.
My web.xml defines 2 different resource-refs for my databases, jdbc/development and jdbc/production. There is also a global context-param named database with values of development or production that defines which database the web app should be using.
I have two database pools set up under SJAS9 for these resource names, and the servlets can access these just fine using :
    protected Connection getConnection() {
        Connection conn = null;
        try {
            String datasourceName = "jdbc/" + getServletContext().getInitParameter("database");
            Context initCtx = new InitialContext();
            Context envCtx = (Context)initCtx.lookup("java:comp/env");
            DataSource ds = (DataSource)envCtx.lookup(datasourceName);
            log.debug("retrieving database connection for " + datasourceName);
            conn = ds.getConnection();
            log.debug("done");
            conn.setAutoCommit(false);
            return conn;
        catch (SQLException ex) {
            log.error("error getting a connection", ex);
            return null;
        catch (NamingException ex) {
            log.error("error finding the datasource", ex);
            return null;
    }I have just added a web service to the project, and I can't find a way to get the context param. When I created the web service, Netbeans added some annotation around it, and it is not extended any class or implementing any interface (that I can see).
For the web service, there is no appropriate method equivalent for the call
            String datasourceName = "jdbc/" + getServletContext().getInitParameter("database");so how do I retrieve the context param database so I can know which resource pool to obtain the connection from inside the web service?
Thanks

Here's how to invoke getServletContext() from a web service:
First you'll need to add "ServiceLifecycle" to the list of implmentations of your class:
public class MyService implements WebServices.MyServiceSoap, Remote, ServiceLifecycle {}Next you'll need to add the following:
private ServletContext servletContext;
public void destroy(){}  
public void init(Object context) throws javax.xml.rpc.ServiceException {
   ServletEndpointContext soapContext = (ServletEndpointContext) context;
   servletContext = soapContext.getServletContext();
Hope this helps!
