Configuring an EJB client using the Burlap protocol uses the
BurlapContextFactory as a JNDI link. The client will use
JNDI to lookup the EJB home interfaces.
Resin-EJB with Burlap
<web-app>
<jndi-link>
<jndi-name>java:comp/env/ejb</jndi-name>
<jndi-factory>com.caucho.burlap.BurlapContextFactory</jndi-factory>
<init-param java.naming.provider.url="http://host.com/burlap"/>
</jndi-link>
</web-app>

Sample client code follows. The EJBHome lookup is in the init()
method for efficiency.
Client Servlet
import javax.servlet.*;
import javax.namingdservlet.*;
public class ClientServlet extends GenericServlet {
TestHome home;
public void init()
throws ServletException
{
try {
Context env = (Context) new InitialContext().lookup("java:comp/env");
home = (TestHome) env.lookup("ejb/test");
} catch (Exception e) {
throw new ServletException(e);
}
}
public void service(ServletRequest req, ServletResponse res)
throws IOException ServletException
{
try {
PrintWriter out = res.getWriter();
Test test = home.findByPrimaryKey("test");
out.println("test:" + test.hello());
} catch (Exception e) {
throw new ServletException(e);
}
}
}
