Did you try to remove these dispatcher params ? Or add FORWARD ?

Re: SEVERE: Servlet.service() for servlet default threw exception, java.lang.IllegalStateException
Posted by Dave Newton <da...@gmail.com>.
My first guess would be that it's an issue with two different things writing
to the output stream, that often causes illegal state exceptions. Can you do
it in such a way that errors are handled by a result instead off in the
action and see what that does?

For people have similar questions, my solution for now based on ajax +
jQuery is:
=========================================================================
(1) In global tile template.jsp, added
<div id="ajax_error_div" align="left">
</div>
(2) In script.js, defined:
==============================
function ajax_check(url)
{
var xmlhttp;
var str = $("form").serialize(); //http://api.jquery.com/serialize/
var tmp_str = "";
if (window.XMLHttpRequest)
{// code for IE7+, Firefox, Chrome, Opera, Safari
xmlhttp=new XMLHttpRequest();
}
else
{// code for IE6, IE5
xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
}
xmlhttp.onreadystatechange=function()
{
if (xmlhttp.readyState==4 && xmlhttp.status==200)
{
document.getElementById("ajax_error_div").innerHTML =
xmlhttp.responseText;
}
}
xmlhttp.open("POST", url, false);
xmlhttp.setRequestHeader("Content-type","application/x-www-form-urlencoded");
xmlhttp.send(str);
var str = document.getElementById("ajax_error_div").innerHTML;
if(str == null || str.trim() == "")
{
return true;
}
return false;
}
(3) main_display.jsp
=======================
<s:submit value="Search"
theme="simple"
onclick="return ajax_check('ajax_checkProcessAction')"
action="searchProcessAction" />
(4) struts.xml
=================
<action name="*ProcessAction" method="{1}" class="ProcessAction">
<result name="success" type="tiles">browse_main_page</result>
<result name="error" type="tiles">browse_main_page</result>
<result name="ajax_check" >
/WEB-INF/pages/errorinfo/ajax_error_check.jsp
</result>
</action>
(5) ajax_error_check.jsp
==========================
<%@ taglib prefix="s" uri="/struts-tags" %>
<s:if test="hasActionMessages()">
<center>
<div id="action_message_div"
style="width: 700px; border:thin solid black;
background-color:#C5D1C0; padding-left: 10px; margin-bottom: 5px; "
align="left">
<s:iterator value="actionMessages">
<li>
<B><s:property escape="false" /> </B>
</li>
</s:iterator>
</div>
</center>
</s:if>
<s:if test="hasActionErrors()">
<center>
<div align="left" style="width: 700px; border:thin solid black;
background-color:#D0CCAE; padding-left: 10px; margin-bottom: 5px">
<s:iterator value="actionErrors">
<li>
<B><s:property escape="false" /> </B>
</li>
</s:iterator>
</div>
</center>
</s:if>
Thank you for all inputs!

Situation is:
=====================
(1) a.jsp
part1 -> search form
part2 => huge calculation in ActionClass.java;
results are shown by using displaytag
(2) Checks are needed in part1, but I need avoid calculation in part2.
Moreover, a.jsp only part1 will be reloaded, but not the whole page.
part1@a.jsp calls method1 in ActionClass.java
(3) JSON/jquery sj:submit seems does not support "action" parameter, it
could not dispatch to another method, isn't ?
<sj:submit targets="result"
button="true"
validate="true"
validateFunction="customeValidation"
onBeforeTopics="removeErrors"
onSuccessTopics="removeErrors"
value="Submit"
indicator="indicator"
action="method1ProcessActionClass" //does not dispatch! while
s:submit works
/>
Could you suggest a good way?
====================================
(1) Do not reload whole jsp
(2) Calculation must be done through ActionClass.java (extends
ActionSupport)
The calculation is through database queries, so have to be done
through action class.
According to the check results, display error message to users
through part1@a.jsp
Only if no error return, part2 will be calculated and reloaded.
Thanks alot!
Emi

Did you try to call check_search_oprProcessAction.action directly ?
And maybe it's better to JSON plugin instead of home made protocol ?
Kind regards

It seems that I found the problem. When I commented out ajax section
"onclick="return ajax_check_search_table('check_search_opr')"", the
error is gone. But I need ajax check support.
Do you know why ajax and which parts in ajax cause this exception?
Thanks a alot!

Could you list the jars in WEB-INF/lib ? It looks like you're mixing
different version of jars.

I tried as well, but still got the following exceptions. The server did
not die and it seems work fine. But each action returns such SEVERE
exception. Why???
tomcat6 + struts2.2.3 + tiles2.2.2 + springframework3.05 + displaytag 1.2.
I do need help what may cause this exception. From the outputs, I cannot
see any hint!
