PlugIn TimerTask
Hello,
I have implemented an automatic process in
Struts/Tomcat by starting a Timer and scheduling a
TimerTask in the init() method of a PlugIn class.
It works pretty well, except for one thing: if I stop
Tomcat while the task is running, according to the
Timer specification the task should be allowed to
finish, but in fact it is ended in the middle of its
process.
Is this a Struts effect? Can someone figure out how to
fix this?
Thanks!
Guifre

Yes, that's exactly how I'm bypassing the problem, but
I would very much prefer to have something so basic
working as expected: it might affect other similar
situations.
I hope someone can explain why the task is ended?

How about have your TimerTask set a flag in your Plugin when its running,
then in your Plugin.destroy() method, cancel the timer and wait until any
running task is finished.
public class MyPlugin implements Plugin {
public void setTaskRunning(boolean taskRunning) {
this.taskRunning = taskRunning;
}
public void init(ActionServlet servlet, ModuleConfig config) {
timer.schedule(new MyTimerTask(this), .......);
}
public void destroy() {
Timer.cancel();
while (taskRunning = true) {
wait(1000);
}
}
}

I'm using just Timer() to avoid the "daemon" effect.
As for the Tomcat list, I've considered it, but I
think that having Struts at the center of the action
will raise every suspicion...

How are you creating your Timer() object? If you're passing true ("new
Timer(true)") then the jvm will kill your timer task when then app ends. If
you're just using "new Timer()" or passing false, well, then maybe you can
ask the Tomcat list. :)

Problem with tiles
Posted by Michiel Slot <sl...@productandconcept.com>.
Ok, fixed my previous problem:
'org.apache.struts.tiles.ActionComponentServlet' has been removed.
So instead of that I now use the plug-in tag. Strangely enough it returns
white pages with an empty HTML body with only a queer ONUNLOAD in it,
sometimes. What goes wrong? With Struts 1.1 everything goes fine...
Web.xml:
<servlet-class>org.apache.struts.action.ActionServlet</servlet-class>
...
<taglib>
<taglib-uri>/tags/struts-nested</taglib-uri>
<taglib-location>/WEB-INF/struts-nested.tld</taglib-location>
</taglib>
Struts-config.xml:
<controller processorClass="org.apache.struts.tiles.TilesRequestProcessor">
<plug-in className="org.apache.struts.tiles.TilesPlugin" >
<set-property property="definitions-config" value="/WEB-INF/tiles-defs.xml"
/>
<set-property property="definitions-parser-validate" value="true" />
<set-property property="moduleAware" value="true" />
</plug-in>
Thanks

An: 'Struts Users Mailing List'
Betreff: ServletException: Class
`org.apache.struts.tiles.ActionComponentServlet'
I've chosen to upgrade to Struts 1.2 to apply wildmatches to my
Tiles-actions.. After upgrading from Struts 1.1 to 1.2(I've tried several
recent nightly builds) I get the following error while opening a page:
javax.servlet.ServletException: Class
`org.apache.struts.tiles.ActionComponentServlet'
What is happening? When I explore the package org.apache.struts.tiles it
seems to me that ActionComponentServlet is gone... what to do now?
