Hello,
I try to deploy a simple spring portlet in ext (I can't use Plugins SDK...) on Liferay 5.2.3
My portlet:
ext-impl/src:
package: com.ext.portlet.springmvc
HelloWorldController.java
[code]
package com.ext.portlet.springmvc;
import java.io.IOException;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.Controller;
public class HelloWorldController implements Controller {
public ModelAndView handleRequest(HttpServletRequest request,
HttpServletResponse response) throws ServletException, IOException {
String aMessage = "Hello World MVC!";
ModelAndView modelAndView = new ModelAndView("hello_world");
modelAndView.addObject("message", aMessage);
return modelAndView;
}
}
[/code]

Are there some mistakes?
I get this error, when I try to deploy:
[code]

ith name 'com.liferay.portal.kernel.captcha.CaptchaUtil' defined in class path r
esource [META-INF/util-spring.xml]: Cannot create inner bean 'com.liferay.portal

[/code]
Hope anybody can help me...
Thank you very much.
