How to unpackage and repackage a WAR file
JavaMavenWeb Applicationsjboss7.xWarJava Problem Overview
I have a WAR file. I would like to open it, edit an XML file, remove some jars and then re-package it.
I used WINRAR to open the WAR file and I removed some Jars and did an 'Add to Archive' in WinRar and created a WAR.
When I deployed the WAR in jboss folder, I got an exception.
16:05:14,316 ERROR [org.jboss.msc.service.fail] (MSC service thread 1-2)
MSC00001: Failed to start service jboss.deployment.unit."myapplication.war".
STRUCTURE: org.jboss.msc.service.StartException in
service jboss.deployment.unit."myapplication.war".STRUCTURE:
Failed to process phase STRUCTURE of deployment "myapplication.war"
How do I repackage the WAR ?
Java Solutions
Solution 1 - Java
you can update your war from the command line using java commands as mentioned here:
jar -uvf test.war yourclassesdir
Other useful commands:
Command to unzip/explode the war file
jar -xvf test.war
Command to create the war file
jar -cvf test.war yourclassesdir
Eg:
jar -cvf test.war *
jar -cvf test.war WEB-INF META-INF
Solution 2 - Java
copy your war file to /tmp now extract the contents:
cp warfile.war /tmp
cd /tmp
unzip warfile.war
cd WEB-INF
nano web.xml (or vim or any editor you want to use)
cd ..
zip -r -u warfile.war WEB-INF
now you have in /tmp/warfile.war your file updated.
Solution 3 - Java
This worked for me:
mv xyz.war ./tmp
cd tmp
jar -xvf xyz.war
rm -rf WEB-INF/lib/zookeeper-3.4.10.jar
rm -rf xyz.war
jar -cvf xyz.war *
mv xyz.war ../
cd ..

Adapting from the above answers, this works for Tomcat, but can be adapted for JBoss as well or any container:
sudo -u tomcat /opt/tomcat/bin/shutdown.sh
cd /opt/tomcat/webapps
sudo mkdir tmp; cd tmp
sudo jar -xvf ../myapp.war
#make edits...
sudo vi WEB-INF/classes/templates/fragments/header.html
sudo vi WEB-INF/classes/application.properties
#end of making edits
sudo jar -cvf myapp0.0.1.war *
sudo cp myapp0.0.1.war ..
cd ..
sudo chown tomcat:tomcat myapp0.0.1.war
sudo rm -rf tmp
sudo -u tomcat /opt/tomcat/bin/startup.sh
Solution 5 - Java
I am sure there is ANT tags to do it but have used this 7zip hack in .bat script. I use http://www.7-zip.org/ command line tool. All the times I use this for changing jdbc url within j2ee context.xml file.
mkdir .\temp-install
c:\apps\commands\7za.exe x -y mywebapp.war META-INF/context.xml -otemp-install\mywebapp
..here I have small tool to replace text in xml file..
c:\apps\commands\7za.exe u -y -tzip mywebapp.war ./temp-install/mywebapp/*
rmdir /Q /S .\temp-install
You could extract entire .war file (its zip after all), delete files, replace files, add files, modify files and repackage to .war archive file. But changing one file in a large .war archive this might be best extracting specific file and then update original archive.
Solution 6 - Java
Non programmatically, you can just open the archive using the 7zip UI to add/remove or extract/replace files without the structure changing. I didn't know it was a problem using other things until now :)
Solution 7 - Java
Maybe, you have modified the structure of the war or deploying it on a different server version. Checkout these links https://stackoverflow.com/questions/18855728/error-deploying-war-into-jboss-as-7-domain-mode-failed-to-process-phase-struc and https://community.jboss.org/thread/199387?start=0&tstart=0&_sscc=t
Solution 8 - Java
no need to that, tomcat naturally extract the war file into a folder of the same name. you simply modify the desired file inside that folder (including .xml configuration files), that's all. technically no need to restart tomcat after applying the modifications
