RE: Question about Jetspeed JSP/Portlet
Hi Erzhuan,
you read my posting about the improved JSP portlet, didn't you?
So you retrieved my code, didn't you? This code for a portlet using JSP is
capable to display the portlet's content using a JavaServer page.
Additionally it is also able to react on action events. I implemented it in
the way the Velocity portlets work.
So if your URL includes ?action=doSomething and you specified an action
inside of the portlet-entry the method doSomething() of the action object
should be executed. The action object is tied to the portlet entry like
that:
<parameter name="action" value="portlets.MyAction"/>
Like that the class name for the action object is this one:
org.apache.jetspeed.modules.actions.portlets.MyAction
There is another thing:
I think you cannot directly access the portlet through its JSP page. So
don't insert a link like:
http://localhost/jetspeed/hello.jsp?action=doSomething
The link should be generated by the class PortletTemplateLink. In the
current version of Jetspeed this class is deprecated. But I don't know
anything about the new stuff.
hope that helps.
don't hesitate to contact me in case of further questions
Matt

RE: Redirecting in jsp
Posted by Steen Bjerre Andersen <st...@bjerre-andersen.dk>.
I found another solution. I've made a jsp portlet that just contains an
iframe and nothing else. The src for the iframe is my search page
(soeg.jsp). Soeg.jsp is placed outside Jetspeed in another webapplication
under Tomcat. Now redirecting works within the jsp portlet.

I see what you mean. I do rem running into that problem sometime ago and I
could fnd no soultion so I was forced to use...
<META HTTP-EQUIV=Refresh CONTENT="0; URL=<%= next_url %>"/>
This will work... Not the 'java' soultion but it works.
Good Luck.

Ok here it is. I commented out all redirects, but one. I've also tried
<jsp:forward...> instead of redirect.
When I use action="" in the form, the form is submitted to soeg.jsp itself.
I can request the input fields and print them with out.println. When I use
action="<jetspeed:link template="soeg.jsp" />"> I have no idea as to where
the form is submitted, I get a blank page, with the jetspeed top and side
bars. I get the IllegalState exception no matter what the action is set to
in the form.
soeg.jsp is placed in WEB-INF/templates/jsp/portlets/html/
I'm running Jetspeed 1.4b1 under Tomcat 4.0.

Humm, that means that somwhere in your code you were already trying to a
redirect...
Why dont you send the entire code content...
you cant use <jsp:forward page="<%= next_url %>"/>
and some other form of redirect as well
and if worse comes to worse try...
<META HTTP-EQUIV=Refresh CONTENT="0; URL=<%= next_url %>"/>

That does not help. I still get "IllegalStateException: Cannot forward
after response has been committed".
It seems like that I cannot use the response object from the RunData object.
When I try:
HttpServletResponse resp = rundata.getResponse();
resp.isCommited();
it returns true. Maybe it is because I submit my form to the jsp page
itself?
