html:link throwing null pointer
Hi all,
I'm in the process of upgrading our J2EE app from struts 1.2.4 to 1.3.8.
We're also using tiles.
I'm able to see the header tile but when it reaches the search.jsp tile
I get:
javax.servlet.jsp.JspException: ServletException in '/WEB-INF/jsp/common/search.jsp': null
at org.apache.struts.tiles.taglib.InsertTag$InsertHandler.doEndTag(InsertTag.java:927)
at org.apache.struts.tiles.taglib.InsertTag.doEndTag(InsertTag.java:465)
at _web_2d_inf._jsp._common._layout._jspService(_layout.java:142)
[SRC:/WEB-INF/jsp/common/layout.jsp:81]
.....
.....
here's my jsp:
<%@ taglib uri="http://struts.apache.org/tags-html" prefix="html"%>
<%@ taglib uri="http://struts.apache.org/tags-bean" prefix="bean"%>
<html:xhtml />
<%--<bean:define id="currentDate" name="java.util.Date" type="java.util.Date" />--%>
<jsp:useBean id="curDate" class="java.util.Date" />
<div id="Search">
<p class="Time">
<bean:message key="prompt.Cyprus" />
<bean:write name="curDate" format="HH:mm:ss zz" />
</p>
<form action="#">
<p>
<label for="SearchSelect"><bean:message key="prompt.search" />:</label>
<select name="SearchSelect" id="SearchSelect">
<option selected="selected">Select...</option></select>
<input type="text" name="SearchInput" id="SearchInput" class="Text" />
<input type="submit" name="SearchBTN" id="SearchBTN" class="SearchBTN" value="Search" />
<html:link href="http://www.google.gr">
<bean:message key="prompt.advanced.search" />
</html:link>
<%--<a href="#">Advanced Search</a>--%>
</p>
</form>
</div><!-- Search -->
I'm certain it's html:link, because if I comment it out the tile is showing. I've also checked with
html:img and it shows fine, so this must be specific to html:link. Any ideas?
Thanks
Dimitris

Struts 1.3.9 is release. It was declared as beta for this bug:
https://issues.apache.org/struts/browse/STR-3081
See the mail thread:
http://www.nabble.com/-S1---VOTE--Struts-1.3.9-Quality-td11486284.html
Eventually you want Struts 1.3.10 to be released, but for these
questions I think you may want to ask the Struts Developers mailing
list:
http://struts.apache.org/dev/dev-mail.html

But 1.3.9 is still beta. btw do you know when it will be released?
Anyway I've just installed the new jar and everything is working great now.
A great thank you to you Antonio, for all your support.

I don't think it is necessary, it has been released in 1.3.9.

I think it's a bug though. Check this out:
https://issues.apache.org/struts/browse/STR-3015
I've corrected the code and I'm trying to find out how to rebuild struts.

Is there a cause for this exception? Or a stack trace that appears
before this one?
