Hi,
I want to config a JNDI data source in an embedded tomcat which is started in Eclipse
I've tried several methods, but no one worked well.

First, I tried to indicate a configuration file which include a data source configuration
StandardContext standardContext = (StandardContext) embedded.createContext("/web", "E:/Project/MyJava/TomcatProj/web");
standardContext.setConfigFile("E:/Project/MyJava/EmbeddedTomcat/conf/webexp.xml");
host.addChild(standardContext);

but no data source could be found:
try {
  InitialContext initial = new InitialContext();
  DataSource dsource = (DataSource)initial.lookup("jdbc/SQLServer");
  if (dsource != null) {
    System.out.println("Data source has found!");
  }
} catch (Exception e) {
  e.printStackTrace();
}

The exception described like that:
javax.naming.NameNotFoundException: Name jdbc is not bound in this Context
at org.apache.naming.NamingContext.lookup (NamingContext.java:815)
at org.apache.naming.NamingContext.lookup (NamingContext.java:198)
at org.apache.naming.SelectorContext.lookup (SelectorContext.java:183)
at javax.naming.InitialContext.lookup (InitialContext.java:347)
at com.gul.struts.LoginAction.getUser(LoginAction.java:35)
at com.gul.struts.LoginAction.execute(LoginAction.java:96)
......


Then, I tried the second method:
  StandardContext rootCtx = (StandardContext)embedded.createContext("/web", "E:/Project/MyJava/EmbeddedTomcat/web");
  rootCtx.setWorkDir("E:/Project/MyJava/EmbeddedTomcat");

  ContextResource res = new ContextResource();
  res.setName("jdbc/SQLServer");
  res.setType("javax.sql.DataSource");
  res.setAuth("Container");


  ResourceParams params = new ResourceParams();
  params.setName("jdbc/SQLServer");
  params.addParameter("factory", "org.apache.commons.dbcp.BasicDataSourceFactory");
  params.addParameter("maxActive", "50");
  params.addParameter("maxIdle", "10");
  params.addParameter("maxWait", "10000");
  params.addParameter("username", "root");
  params.addParameter("password", "");
  params.addParameter("driverClassName", "org.gjt.mm.mysql.Driver");
  params.addParameter("url", "jdbc:mysql://localhost/employee");


  rootCtx.getNamingResources().addResource(res);
  rootCtx.getNamingResources().addResourceParams(params);
 
  host.addChild(rootCtx);
But, still the exception was thrown.

Could anybody give me a help?
Thanks
