JAR or zip

[ankur rathi]

Hi,

Please let me know what to create.

Assignment mentions JAR and mail mentions zip. If JAR, then how to create JAR of some HTML files and images.

Thanks a ton.

You can use the jar command line tool to create jar files. See http://java.sun.com/docs/books/tutorial/deployment/jar/basicsindex.html for details.

Thanks Ulf.

I created a jar using following command: jar cf test.jar *.*

But when I extract it using: jar xf test.jar

It just generates one META-INF folder and MANIFEST.MF file inside it. Where are html files and images?

Thanks!

Sorry guys.

It actually overrided old files (since I unzipped in the same folder).

You can use "jar tf test.jar" to list the contents of the jar file. If you use "jar xf" right after "jar cf", then all files in the directory will be overwritten by the contents of the jar file, so you wouldn't notice any additional files.

You can just simply zip your files and rename result file to jar. Jar files are just zipped files with .jar extension.

hi to all,
I've submitted my assignment this morning, the jar with "jar cvf scea-xxxx.jar scea-xxxx/*"

only one doubt, if you use "jar xf scea-xxx.jar" you can see all the files in the cwd, but if you extract with winrar/winzip su see a dir scea-xxxx that contains all the files.

It's ok or I've made a mistake? :-S


Thanks in advance.
