Unexplained exception in my portlet

[arnaud inizan, geändert vor 12 Jahren.]

Hi everyone :

I want to define my own sign in portlet, but here is what I get when the SignInPortlet.java is called :

I really can't understand, the struts.jar is in my liferay lib, I also try to add it in my SignIn portlet, but no way, it doesn't work; any idea ??
In my code, i can even type" org.apache.struts.action.ActionMapping" and Eclipse recognize the class, so where the hell is the problem ??

Thanks.

Your plugin properties file (deployed with your plugin) must include the struts requirement. When deployment occurs, the right struts jar will be included in your deployed portlet and all should be fine. You shouldn't have to include jars directly in your plugin that are available from Liferay's jars (you only include those that Liferay doesn't supply).

Did you added jar files into your project or adding external jar. If your adding external jar files then make sure that jar must be from liferay only.

[vasugi andavar, geändert vor 11 Jahren.]

Hi,
Thank you for replying. I do not have any external jars added to my portlet. The struts.jar is within the liferportal/WEB-inf/lib folder.
And i also extracted the struts.jar from portal to web-inf/classes. But still it is not working. Having the same issue still.

Can anybody please help me on this. I am struggling on this for 2 days.

[Jiangtao Qiu, geändert vor 11 Jahren.]

Ok，This problem is resulted from a bug of Lifery 6.0.5 http://issues.liferay.com/browse/LPS-16517
Hence, you can solve the problem by using version 6.1 or overwritting invokeTaglibDiscussion method, implemented in MVCPortlet class, in your portlet class.

As mentioned by Amos Fong, the method may be like ollowing codes

public void invokeTaglibDiscussion(
            ActionRequest actionRequest, ActionResponse actionResponse)
        throws Exception {

        Object[] args = new Object[] {
                new NullWrapper("org.apache.struts.action.ActionMapping"),
                new NullWrapper("org.apache.struts.action.ActionForm"),
                getPortletConfig(), actionRequest, actionResponse
            };

            PortalClassInvoker.invoke(
                "com.liferay.portlet.messageboards.action.EditDiscussionAction",
                "processAction", args);
    }
