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!

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
