WAR deployment incomplete (sometimes)
Hello everyone,
I am having a problem with WAR deployment. I am performing a static
deployment: copying a ROOT.war under the webapps directory, and then
starting Tomcat (no other web applications). On most occasions, the
deployment is successful. However, occasionally the deployment does not
succeed, and the WAR is only partially unpacked. Subsequently stopping
Tomcat, deleting the expanded webapp directory, and starting Tomcat
again will (normally) result in a successful deployment. When this
happens, I see no exceptions in the logs. I've looked at the Tomcat
source responsible for WAR expansion, and found no clues.
I have begun collecting data to establish whether the unpacking always
stops at the same point in the WAR, but only have one data point so far.
I have verified that the WAR unpacking stops at a sequential point (all
files before that point are unpacked, and all files after that point
have not been unpacked). In the single instance I have recorded,
unpacking stops between two similar, and unremarkable HTML files.
This problem has occurred on Solaris, Linux (Redhat), and Windows, so
this problem is not platform-specific.
I've searched the mailing list archives, and I can find no reference to
others having the same problem. Can anyone offer an explanation or
solution?
Thanks,
Mike

Those settings only affect Windows installations, and the OP clearly
stated that the problem occurs on Solaris and Linux as well.

issue occurs on windows, linux and solaris. Manual unpacking of WAR (jar -xf
ROOT.war) does not fail; all files are correctly unpacked.
Thanks though.

You can easily test the WAR file with either
$ jar tvf <jar-file>
or
$ unzip -tv <jar-file>
InfoZip's UnZip says that "-t" does a "test", while the jar utility only
says that it will list the table of contents. I would use unzip if you
have it available. I suppose using jar to unzip your jar file (instead
of merely listing the TOC) would be a good test.
Ideally, the WAR expansion is non-destructive (I hope so!), so after a
crash like this you should be able to check the WAR file for integrity.
Who knows... you might have some bad space on your disk. That might
explain the intermittent nature of your problem.
If you have physical access to your machine you could run badblocks (for
a Linux machine... dunno if something similar is available for Sun) or
even memtest86 (x86 hardware only, of course) to check to see if you
have any hardware issues. It's possible that unzipping your WAR file
sometimes exposes a problem with your memory<->cpu communication.
Usually other weird things happen when you have such a problem. Since
nobody can figure out your problem, I figured I'd mention that it could
be a hardware problem. It's odd, though, that you would experience the
same problem on multiple machines in a short period of time. <shrug>

The SAVE Michael PROJECT.... chapter 51
Ok... another guess...
One of the things that has always bothered me is that Tomcat doesnt really
have a root
it has a special folder called ROOT... and if you say change the name to say
START and leave the context path = "".... it ignores that... it wont
treat... "start" like.... "root".
ROOT is clearly a very special name....
So I got another wild theory... Michael.... change the name of your war
file...
to say..... rearEndPain...
Dump it in tomcat and see if it unpacks.... if so... the problem is in the
name...

Hi Michael... shame still struggling with this.
One thing you not telling us is wot is packaging the WAR.
A WAR is basically a zip... but I do know that if you zip using external
programs like AlZip or WinZip... the Java zip api can struggle with
that.
Also if you using netbeans right click on the project and have a look if
its
using compression... take that off and then its plain... bigger... but
plain.. anything should open that file.
Super Compression is a recent addition to Java.... maybe the jre u using
is
just when it was introduced.... ie the dev environment is higher version
than the runtime env.
I dont think 23mb should be any problem for a zip...

Thanks for your comments,
I have a collected a second data point, which shows that the WAR does
not stop unpacking at the same point every time. The first recorded
incident was on Solaris, and this second incident was on Windows.
Again, there was no exception or error message in the Tomcat logs.
The WAR file contains 1461 entries (~23MB). Solaris stopped after 797
entries. Windows stopped after 1326 entries. I doubt future incidents
on the same platforms will stop at the same points.
I've searched the Sun Java bug database, and found lots of interesting
JRE JAR/WAR/zip bugs, triggered by such things as JARs larger than 2GB
(large file support), and JARs with more than 64,000 entries, but none
of the bugs apply to my situation.

It's not a bug - it was user error due to the invalid <Context>
attributes. (Do we really need to discuss those again?) Follow the
rules and it unpacks fine. Perhaps a ill-formed context.xml is part of
this problem.

If this app is not top secret.... I would send it to a guru, someone like
Caldarale, Charles and let him play with it.
I think if the Tomcat guru's could see it first hand... you would find your
solution.
I've just made a 32mb ROOT.WAR..... it unpacks, so their goes my theory ;)

That bug refers to a ROOT.war that NEVER correctly unpacks (so it's
repeatable), and although it doesn't say explicitly, I think the WAR
unpacks completely, but the webapp isn't initialized properly because
Tomcat doesn't like the context declaration.
My WAR contains no context.xml -- it is just named ROOT.war, and expects
to be deployed in the root context based on Tomcat's special ROOT
handling.
I've got my script running in an attempt to reproduce the unpack
failure, and I think I'm going to leave it running over the weekend.

incident was on Solaris, and this second incident was on Windows.
Again, there was no exception or error message in the Tomcat logs.
The WAR file contains 1461 entries (~23MB). Solaris stopped after 797
entries. Windows stopped after 1326 entries. I doubt future incidents
on the same platforms will stop at the same points.
I've searched the Sun Java bug database, and found lots of interesting
JRE JAR/WAR/zip bugs, triggered by such things as JARs larger than 2GB
(large file support), and JARs with more than 64,000 entries, but none
of the bugs apply to my situation.

Subject: WAR deployment incomplete (sometimes)
Hello everyone,
I am having a problem with WAR deployment. I am performing a static
deployment: copying a ROOT.war under the webapps directory, and then
starting Tomcat (no other web applications). On most occasions, the
deployment is successful. However, occasionally the deployment does not
succeed, and the WAR is only partially unpacked. Subsequently stopping
Tomcat, deleting the expanded webapp directory, and starting Tomcat
again will (normally) result in a successful deployment. When this
happens, I see no exceptions in the logs. I've looked at the Tomcat
source responsible for WAR expansion, and found no clues.
I have begun collecting data to establish whether the unpacking always
stops at the same point in the WAR, but only have one data point so far.
I have verified that the WAR unpacking stops at a sequential point (all
files before that point are unpacked, and all files after that point
have not been unpacked). In the single instance I have recorded,
unpacking stops between two similar, and unremarkable HTML files.
This problem has occurred on Solaris, Linux (Redhat), and Windows, so
this problem is not platform-specific.
I've searched the mailing list archives, and I can find no reference to
others having the same problem. Can anyone offer an explanation or
solution?
Thanks,
Mike

Hi Michael... shame still struggling with this.
One thing you not telling us is wot is packaging the WAR.
A WAR is basically a zip... but I do know that if you zip using external
programs like AlZip or WinZip... the Java zip api can struggle with that.
Also if you using netbeans right click on the project and have a look if its
using compression... take that off and then its plain... bigger... but
plain.. anything should open that file.
Super Compression is a recent addition to Java.... maybe the jre u using is
just when it was introduced.... ie the dev environment is higher version
than the runtime env.
I dont think 23mb should be any problem for a zip...

Oh... sorry think I gave wrong impression... I understood article to be
talking about the
META-INF context file... ie one guy said his web.xml file does not appear
after deploy, and said he discovered it has nothing to do with web xml, its
because the the context xml file has the wrong xml format.... personally I
think everyone is guessing, but it certainly does seem to be happening to
some unlucky people.

Found this article.....
http://archives.devshed.com/forums/java-118/missing-application-web-xml-1620719.html
Other stuff I found seems to suggest that it is unpacking... but then Tomcat
is deleting it.
Some say reason is because windows locking open files... but we ruled that
out.
This article suggests that its when the XML integrity is in question.... so
check that... in netbean you can just right click and check XML... article
also suggests that the context is the main problem... so try this one...
works on my system
<?xml version="1.0" encoding="UTF-8"?>
<Context path=""/>
Good luck

Tomcat is not running. In the scenario where the deployment has failed,
Tomcat has never been running. Tomcat is installed as part of another
application. The ROOT.war file is pre-installed under the webapps
directory. At this point, they are just files on disk. Then Tomcat is
started, the ROOT.war is detected, and unpacked. However, sometimes the
WAR is not completely unpacked. Tomcat completes startup, but because
the webapp's web.xml is near the end of the WAR file (i.e., this file is
not unpacked), the webapp does not initialize correctly. At this point,
Tomcat is running (i.e. it did not crash during unpacking), but the web
application is broken. To recover, stop Tomcat, delete the (incomplete)
webapp directory, and start Tomcat again.

Re: WAR deployment incomplete (sometimes)
Posted by Filip Hanik - Dev Lists <de...@hanik.com>.
here is what happens,
your start copying in a large .war file, tomcat detects this file before
the upload is complete and starts expanding it,
tomcat receives a ZipFileCorrupted error (as the upload hasn't
completed) and aborts the deployment
you need to work around the fact that your upload is "taking time"

Re: WAR deployment incomplete (sometimes)
Posted by Johnny Kewl <jo...@kewlstuff.co.za>.
Ok.... another guess and another war story ;)
I found that if I did a URLConnection in a filter init.... I managed to
completely lock up Tomcat on a start.... stone dead...
I then deleted the War and the folder and after figuring out wot the problem
was, it would still not deploy the new one and start... only if I deleted
the conf/Catalina/host/(web-app).xml file did it recover.
So please try this as well... if there is a conf/Catalina/host/(web-app).xml
with the same name as you want to deploy... kill that as well.
ROOT.war is a little special... so wot I'm suggesting is you make sure that
you destroy any traces of a previous version in (conf and web-apps).
I've being trying to replicate wots happening to you and I cant... so sorry
run out of other ideas... but just to recap my weird experiences...
-- Netbeans can hang onto Tomcat...
-- A filter can cripple tomcat...
-- And the common factor seems to be if the context path under
conf/Catalina/host/webAppName.xml is still pointing at something else...
like the netbeans build... it sometimes ignores the WAR....
good Luck....

I don't see a consistent pattern, but it definitely happens on first

product installation, with the WAR file under the webapps directory,
ready for deployment when Tomcat is first started. So the WAR is
intended to only ever be deployed once, and it's failing the first time.
I have seen it fail a second time, so it's not just a new-install issue
either.
To try to reproduce this problem, I wrote a script to repeatedly:
- stop Tomcat
- delete expanded WAR directory
- start Tomcat
- verify WAR expansion
The deployment never failed under these test conditions.

Re: WAR deployment incomplete (sometimes)
Posted by Johnny Kewl <jo...@kewlstuff.co.za>.
Are you developing in netbeans and then droping the dist into Tomcat.... is
that when you see the problem?... if so its not a bad WAR... its because
netbeans for some reason hangs onto tomcat.... ie Tomcat is ignoring the war
because its still running the *build* version in netbeans.
In this case the web-app runs.... but its not the WAR you dropped into
tomcat.
If this is happening and I see in on 5.5.17 and 5.5.23 netbeans 5.5.... the
best way to make it normalize is to open the manager and undeploy it....
that kills the hold netbeans has on tomcat... then drop the WAR in... it
will work.

Hello everyone,
I am having a problem with WAR deployment. I am performing a static
deployment: copying a ROOT.war under the webapps directory, and then
starting Tomcat (no other web applications). On most occasions, the
deployment is successful. However, occasionally the deployment does not
succeed, and the WAR is only partially unpacked. Subsequently stopping
Tomcat, deleting the expanded webapp directory, and starting Tomcat
again will (normally) result in a successful deployment. When this
happens, I see no exceptions in the logs. I've looked at the Tomcat
source responsible for WAR expansion, and found no clues.
I have begun collecting data to establish whether the unpacking always
stops at the same point in the WAR, but only have one data point so far.
I have verified that the WAR unpacking stops at a sequential point (all
files before that point are unpacked, and all files after that point
have not been unpacked). In the single instance I have recorded,
unpacking stops between two similar, and unremarkable HTML files.
This problem has occurred on Solaris, Linux (Redhat), and Windows, so
this problem is not platform-specific.
I've searched the mailing list archives, and I can find no reference to
others having the same problem. Can anyone offer an explanation or
solution?
Thanks,
Mike
