HI .i have tried to call a ejb remote deployed on tomee from a tomcat7 plain.
>From the servlet deployed into tomcat plain i have:
@WebServlet(name = "ProvatestejbRemoto", urlPatterns = {"/prova"})
public class ProvatestejbRemoto extends HttpServlet {
private TestBeanRemote myBean = null;
@PostConstruct
public void inizializzaEjb(){
try {
Properties p = new Properties();
p.put("java.naming.factory.initial",
"org.apache.openejb.client.RemoteInitialContextFactory");
p.put("java.naming.provider.url",
"http://localhost:8080/tomee/ejb";);
// user and pass optional
//p.put("java.naming.security.principal", "myuser");// i not use the
security.
//p.put("java.naming.security.credentials", "mypass");// i not use the
security.
InitialContext ctx = new InitialContext(p);
myBean = (TestBeanRemote)
ctx.lookup("java:global/ejbsutomee/TestBean");
//theproject name of the war deployed on tomee is ejbsutomee.war
} catch (Exception e) {
// e.printStackTrace(out);
}
}
protected void processRequest(HttpServletRequest request,
HttpServletResponse response)
throws ServletException, IOException {
response.setContentType("text/html;charset=UTF-8");
PrintWriter out = response.getWriter();
try {
/* TODO output your page here. You may use following sample
code. */
out.println("<!DOCTYPE html>");
out.println("<html>");
out.println("<head>");
out.println("<title>Servlet ProvatestejbRemoto</title>");
out.println("</head>");
out.println("<body>");
out.println("
Servlet ProvatestejbRemoto at " + request.getContextPath() + "
");
out.println("the ejb remote says: " + myBean.hello());
out.println("</body>");
out.println("</html>");
} finally {
out.close();
}
}
}
