problems with my own portlet

[bratkus]

hello folks,

i've successfully developed a portlet in pluto and jetspeed2. Now i want to run the same portlet in JBoss Portal. I've downloaded your helloworld example and read the two .pdf in the docs folder. So i've written the desciptors. Actually i'm using JBoss Portal 2.0b1 + JBoss AS 4.0.1sp1 Bundle for my first steps with your portal. after deploying the portlet in the /deploy folder it appears in the menue of the portal as "calculator" but "onClick" the following exceptions are thrown:

Thanks for reading,

ben

[julien1]

you need to remove the portlet JSP tag TLD file from the war file you are deploying.

[bratkus]

i suggest that you mean the

<taglib-uri>http://java.sun.com/portlet</taglib-uri>
<taglib-location>/WEB-INF/tlds/portlet.tld</taglib-location>


in my web.xml and the

<%@ taglib uri="http://java.sun.com/portlet" prefix="portlet" %> in my jsp

correct?

[julien1]

yes, you should use remove it and use in your JSP :

<%@ taglib uri="/WEB-INF/portal-lib.tld" prefix="n" %>

you don't need to put the taglib as it is automatically imported in the war file when you deploy your web app.

[bratkus]

thanks for your help, but after editing the jsp and the web.xml the, means i've removed
<taglib-uri>http://java.sun.com/portlet</taglib-uri>
<taglib-location>/WEB-INF/tlds/portlet.tld</taglib-location>
in the web.xml and the
<%@ taglib uri="http://java.sun.com/portlet" prefix="portlet" %> in my jsp

the portal can't find the portlet components in the jsp for example:

An error occurred at line: 6 in the jsp file: /WEB-INF/jsp/view.jsp
Generated servlet error:
D:\jboss_portal_2.0-jboss_4.0.1sp1\jboss_portal_2.0-jboss_4.0.1sp1\server\default\work\jboss.web\localhost\OioCalculator\org\apache\jsp\WEB_002dINF\jsp\view_jsp.java:52: cannot find symbol
symbol : variable renderResponse
location: class org.apache.jsp.WEB_002dINF.jsp.view_jsp
PortletURL jaURL = renderResponse.createActionURL();
which i use for my calculator.

[roy.russo]

The error above, is because you are missing:

<portlet:defineObjects/>

[bratkus]

dear roy,

you mean, that in my jsp your posted tag is missing? for a better understanding i've added my jsp:

<%@ page session="false"%>
<%@ page import="de.oio.data.*" %>
<%@ page import="javax.portlet.*"%>
<%@ taglib uri="/WEB-INF/portal-lib.tld" prefix="n"%>
<portlet:defineObjects/>
<% PortletURL jaURL = renderResponse.createActionURL();
PortletSession session = renderRequest.getPortletSession();
String calcAction = (String)session.getAttribute("calcAction");
String calcbin = (String)session.getAttribute("calcbin");
%>
This is a very simple calculator (can only add).


Result : <%= ((Calculator)session.getAttribute("testBean")).getSResult()%>











<input name="calcbin" type="radio" value="bin" <%=calcbin.equals("bin") ? "CHECKED" : ""%>/>bin
<input name="calcbin" type="radio" value="hex" <%=calcbin.equals("hex") ? "CHECKED" : ""%>/>hex
<input name="calcbin" type="radio" value="oct" <%=calcbin.equals("oct") ? "CHECKED" : ""%>/>oct
<input name="calcbin" type="radio" value="fac" <%=calcbin.equals("fac") ? "CHECKED" : ""%>/>n!

[bratkus]

and where can i edit my posts?

[roy.russo]

Use the code tags in the forums when posting code.

Are you still getting the same error after adding this?

[bratkus]

right, the hole jsp looks like this:

<%@ page session="false"%>
<%@ page import="de.oio.data.*" %>
<%@ page import="javax.portlet.*"%>
<%@ taglib uri="/WEB-INF/portal-lib.tld" prefix="n"%>
<portlet:defineObjects/>
<% PortletURL jaURL = renderResponse.createActionURL();
PortletSession session = renderRequest.getPortletSession();
String calcAction = (String)session.getAttribute("calcAction");
String calcbin = (String)session.getAttribute("calcbin");
%>
<P>This is a very simple calculator (can only add).</P>
<div>
<br />
Result : <%= ((Calculator)session.getAttribute("testBean")).getSResult()%>
<br />
<br />
<br />
</div>
<form method="POST" action="<%=jaURL.toString()%>">
<div>
<INPUT TYPE="TEXT" NAME="sNumber1" id="sNumber1" VALUE="0" />
<INPUT TYPE="TEXT" NAME="sNumber2" id="sNumber2" VALUE="0" />
</div>
<br />
<div>
<input name="calcbin" type="radio" value="bin" <%=calcbin.equals("bin") ? "CHECKED" : ""%>/>bin
<input name="calcbin" type="radio" value="hex" <%=calcbin.equals("hex") ? "CHECKED" : ""%>/>hex
<input name="calcbin" type="radio" value="oct" <%=calcbin.equals("oct") ? "CHECKED" : ""%>/>oct
<input name="calcbin" type="radio" value="fac" <%=calcbin.equals("fac") ? "CHECKED" : ""%>/>n!
<br />
<br />
</div>
<div>
<INPUT TYPE="SUBMIT" name="calcAction" id="1" value="sub"/>
<INPUT TYPE="SUBMIT" name="calcAction" id="2" value="add"/>
<INPUT TYPE="SUBMIT" name="calcAction" id="3" value="div"/>
<INPUT TYPE="SUBMIT" name="calcAction" id="4" value="multi"/>
<INPUT TYPE="SUBMIT" name="calcAction" id="5" value="mod" />
<Input type="submit" name="do" value="resolve" />
</div>

</form>

the portaloutput follows:

and as i said before it works in the pluto container and in the jedspeed2 portal

[echoi1975]

hi, in your jsp,
did you include the following to initialize the portlet objects (renderrequest, renderresponse)?

<%@ taglib uri="http://java.sun.com/portlet" prefix="portlet" %>

<portlet:defineObjects/>

then you should be able to reference renderrequest/response inside your scriplets...

[bratkus]

thx for your tips, but the jsp is already fixed.

here is the running version

<%@ page import="de.oio.data.*" %>
<%@ page import="javax.portlet.*"%>
<%@ taglib uri="/WEB-INF/portal-lib.tld" prefix="m"%>
<%@ taglib uri="/WEB-INF/portlet.tld" prefix="portlet"%>
<portlet:defineObjects/>
<%
String calcAction = (String)session.getAttribute("calcAction");
String calcbin = (String)session.getAttribute("calcbin");
%>
<P>This is a very simple calculator (can only add).</P>
<div>
<br />
