Failed to deploy war file for tomcat8

I am trying to deployin a .war file from my computer after modifing one file

  • I Extract the file META-INF/context.xml using :

    jar xf ROOT.war META-INF/context.xml

  • I added some code lines to the file Context.xml

  • I Update the war file with modified META-INF/context.xml using this command :

    jar uf ROOT.war META-INF/context.xml

  • But i get this ERROR :

    at java.util.zip.ZipOutputStream.putNextEntry(ZipOutputStream.java:232)
at java.util.jar.JarOutputStream.putNextEntry(JarOutputStream.java:109)
at sun.tools.jar.Main.update(Main.java:635)
at sun.tools.jar.Main.run(Main.java:271)
at sun.tools.jar.Main.main(Main.java:1288)```

Any Ideas, please!

Solution

  • Hello to all I come back to you after my question, I managed to deploy a war with zip. and jar too, Indeed my error is due to the fact that there are two jar files in /lib that have the same name (weird),
    I deleted the files then I copy/paste only one and it worked.

    with zip i used this steps :

    1: unzip ROOT.war META-INF/context.xml

    2: zip ROOT.war META-INF/context.xml
