getting IOException when parsing template
Hello everyone. I searched the archives for my problem but did not come
up with anything. We are getting a rather strange IOException when
rendering a template, speficially from a #parse directive. Here is the
error message reported in the lgo file:
Exception rendering #parse( user_conf.vm ) : java.io.IOException:
Object state is improper for request.
The strange thing is that this only happens sometimes -- most of the
time it works fine. I could not even find that error text related to
IOException in a google search.
Anyone have any ideas?
Thanks a lot,
Yoel Spotts

Sorry, I should have posted it to begin with. The following parameters
are passed into the context:
1) $doDUR -- a simple Boolean value
2) $allRoles -- a String array
3) $applicants -- an array of HashMaps. Each HashMap contains pairs of
String to String mappings. There is one mapping called mri in the
template which is a simple class which contains several String fields.
I hope this helps. If there is any other information which may be
helpful, please let me know!
Thanks,
Yoel

Look's like it is generated by the sun libraries. Maybe it's an encoding
issue? Do you explicitly set the encoding? If so, to what?

Again, thanks to all who responded -- and especially Mr. Magnusson who
was right on the money as its not a velocity issue. We just installed
the latest service pack to the iplanet web server (which we should have
done to begin with!) and that seems to have solved the problem.
Apparently there was a bug with the iplanet servlet container! Again
thanks to all and all was not lost I guess as I have learnt some
important new things about velocity.

Thank you everyone for your responses. I actually tried the suggestion
offered below -- problem is that it seems that once the exception occurs
-- no matter how we handle it, we have to restart iplanet -- it seems
iplanet gets "stuck" in some sort of state. So it does seem to be
something with iplanet or the java libraries they are using. Frustrating
is all I can say (its much easier to get help with velocity than with
iplanet :). Once again thank you everyone for your help --- it certainly
has been a learning experience. Hopefully we can figure this out! If
anyone has any other suggestions, they are certainly welcome.

Hi,
I catch SocketException in my main request handler. It occurs while you are
writing to a response if the user clicks out.
WILL
protected void doRequest(HttpServletRequest request, HttpServletResponse
response )
throws ServletException, IOException
{
Context context = createContext( request, response );
try
{
Template template = handleRequest( request, response, context );
if ( template == null )
{
return;
}
mergeTemplate( template, context, response );
} catch (java.net.SocketException e) {
// do nothing - page stopped
} catch (IOException e) {
// typically a broken pipe
}
catch (Exception e)
{
/*
* call the error handler to let the derived class
* do something useful with this failure.
*/
try {
error( request, response, e);
} catch (Exception e2) {
}
}
// make sure cleanup always happens, regardless of errors
finally {
try {
requestCleanup( request, response, context );
} catch (Exception E) {
}
}
}

Re: getting IOException when parsing template
Posted by Will Glass-Husain <wg...@forio.com>.
Tomcat gives a SocketException (I think this is a subclass of IOException),
which I usually catch quietly.

Seems like your netscape servlet implementation is unhappy that the
client connection was dropped, and threw a IOException.

Same thing - velocity is flushing bytes out down the OutputStream (the
servlet's output stream) and given that you are clicking fast in your
browser, the connection that you just had is no longer there.
I don't think this is a velocity issue per se - the implementation of
the servlet is sending bytes out to the client as we are flushing them
down the pipe. I can't recall seeing this behavior before, but it's
not surprising.
Can someone get this to happen with tomcat or jetty? I haven't seen it

Re: getting IOException when parsing template
Posted by Yoel Spotts <yo...@secured-services.com>.
Thanks to all who have looked into our issue!
I thought of that as well that the content of the template might have
caused the Exception but really the template does very little -- just
rendering some stuff which was placed in the context. Does not seem
likely. I also should have mentioned we are using velocity within an
iplanet web server.
I modified the velocity source so that it would print the full stack
trace when we recieved this error, and here is what we got:

Bizarre.
What's in user-appl.vm, btw? Anything that might throw an IOException
? :)

Re: getting IOException when parsing template
Posted by Yoel Spotts <yo...@secured-services.com>.
Both machines are using the same JVM. Even with turning caching on, we
are still getting the same error. Following is the complete
velocity.properties:
resource.loader = class
resource.manager.logwhenfound=false
class.resource.loader.class =
org.apache.velocity.runtime.resource.loader.ClasspathResourceLoader
class.resource.loader.cache = true
runtime.log = ../logs/CHCSIIadmin.log
runtime.log.error.stacktrace = true
runtime.log.warn.stacktrace = true
runtime.log.info.stacktrace = true
runtime.log.invalid.references = true
And here is the complete log. Sorry I did not mention it before, but
there are 4 successive IOExceptions generated by succesive clicking on
the link which will cause the template to call the parse:

Are you caching? can you turn caching on? What's wierd is that it's
NT4 and not 2K. Makes me wonder about either JDK impl (are you using
the same JDK on both?) or the OS. What it sounds like is some kind of
collision during I/O?

Re: getting IOException when parsing template
Posted by Yoel Spotts <yo...@secured-services.com>.
Thank you so much for the reply. Sorry I did not give enough
information. Here are some more details which I was able to determine:
I now can re-produce it easily. I only need to click on a link which
will render the template which contains the #parse command quickly more
than once so that the 2nd request fire up before the 1st one finishes.
I am also thinking this could be related to NT4 since I can't duplicate
it in 2K but everytime in NT4.
In addition, I should note we are using velocity 1.3.1.
I in fact had already tried chasing down that error message in the
source code and it took me to
org.apache.velocity.runtime.directive.Parse.java line 245. It appears
the IOException is thrown on line 232 at the render method of
SimpleNode. From there the trail gets more complex since I would assume
it could have been thrown by any one of several subclasses of
SimpleNode. I tried setting runtime.log.error.stacktrace=true in
velocity.properties hoping it would give me a full stack trace in the
log, but it did not.
Finally here are the settings in velocity.properties for the resource
loader:
resource.loader = class
class.resource.loader.class =
org.apache.velocity.runtime.resource.loader.ClasspathResourceLoader
runtime.log = velocity.log
If there is any other information which might be helpful to solving this
issue, please let me know. Thanks again anyone and everyone for the help!

in your template, do you have #parse( user_conf.vm ) or #parse(
"user_conf.vm" )? i think the former should throw an exception during
template parsing, but just in case it doesn't...

blech. no fun. :(
> Anyone have any ideas?
well, this isn't much info to go on. someone might be able to give you some
help if you post some configuration info. particularly, your resource loader
config stuff from velocity.properties. and it might not hurt to mention the
system/environment your working with (since it's an IOException).
as far as investigating further on your own, you may want to run a search
through the source of the libraries you are using to see if you can locate the
exception message text. (i find it's the next best thing when i don't have a
stack trace)
oh, and it never hurts to mention what version of velocity you are using.
