JSP Forwarding

[Tom Cat, geändert vor 12 Jahren.]

Hello,

I have two questions regarding jsp forwarding / linking. I hope you can tell me
how to handle those problems.

1.) There is a method DoView which is executed when my default page is shown. (view.jsp) Why is this method only shown
at the default page and not at the other pages?

2.) Also Liferay provides another method called DoEdit which should do exact same thing like the DoView just with the edit.jsp.
But how can i call the DoEdit method?

Best regards

Tom Cat

Check the portlet modes and portlet lifecycle; you will come to know more.
1. When you load a portlet on a page it is first rendered; thats view mode and the method is doView(). You can write your logic over there to show JSPs of your choice.
2. There are edit and help mode also available.
3. Some special modes are provided by liferay like About, Config, Edit defaults, Edit Guests, Preview, Print.

Hope this helps

Thanks for answering me, but my problem is that i want to generate the content of my jsp with a java class.
And i have four jsps (view, edit, add, delete).

You want to use like it's done in servlets?

just render the html you need in doView, based on the current state of the portlet.

Don't confuse the edit mode (e.g. edit.jsp in standard portlets) with editing your business data. The edit mode is typically used for configuring a portlet. As a rule of thumb whatever you change in the edit mode is typically persisted in PortletPreferences, not in your business specific data. Edit mode is typically only accessed as some kind of administrative action, not by the regular portal user.

You mean you have four jsps and need to render base on some event ?
