One of methods is session token pattern. You can read something for example on this page.

hi manasa,
use sendRedirect method instead of setforward ,it will solve u r problem ........


Comment out this code in u r actionclass
//setForward(req, "your action");

replace with these lines

PortletURL redirectURL = ((ActionResponseImpl) res).createRenderURL();
redirectURL.setParameter("struts_action", "your action");
res.sendRedirect(redirectURL);

Hi Srikanth,

Thank you,
I am developing struts plugin portlet, in action class with execute() the flow goes.
But here request is httpServletRequest and response HttpServletResponse not action response.
When i am using the actionResponseImpl i am getting below exception

ClassNotFoundException

Caused by: java.lang.ClassNotFoundException: com.liferay.portlet.ActionResponseImpl
at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1516)

Thank you in advance..

Hi,

This is not ext.
This is struts plugin portlet...
I want to redirect the page ... I have written the code like this..


response.sendRedirect("/employee/tabs.jsp"); ------------------> It goes to tabs.jsp

It is redirecting but, the page is going to some another jsp not tabs page..

How to give relative / absolute path in sendRedirect ()


could you please tell this...

Thanks in advance

Hi Srikanth,

Thannk you,
I added the all jar files in tomcat/lib, tomcat/lib/ect and tomcat.../web-inf/lib.

I added like below instead of the setForward...

PortletURL redirectURL = ((ActionResponseImpl) response).createRenderURL();
redirectURL.setParameter("struts_action", "portlet.ext.admin.tabs");
response.sendRedirect(redirectURL.toString());

I am developing the plugin portlet, when ever i added the new record it is added successfully, but after that when click on the refresh button
another row is inserted into table...

Thank you in advance.

hi manasa ,
try the below code .......

String portletName = (String)actionRequest.getAttribute(WebKeys.PORTLET_ID);

PortletURL redirectURL = PortletURLFactoryUtil.create(PortalUtil.getHttpServletRequest(actionRequest), porltetName, themeDisplay.getLayout().getPlid(), PortletRequest.RENDER_PHASE);
redirectURL.setParameter("jspPage", "relative path to your ,jsp");


actionResponse.sendRedirect(redirectURL.toString());
