ear file claims no meta-inf in war

[pyrokenesis]

Hello, new to JBoss but not really a novice with development, but cant seem to get the most basic helloworld jsp page on my JBoss server.

My system setup is a Windows 2003 OS, Apache2 server, bundled with Tomcat. IIS is obviously working as well, but turned off.

I have Tomcat on port 8082 and I have JBoss on port 8084. Apache, Tomcat and IIS all work fine. JBoss seems to be working fine but the book I'm using (Beginning Java EE 5: From Novice to Professional, ISBN: 1590594703) has some simple steps to get a jsp showing on server that I cant implement.

After setup, I create a web-app.war with an index.jsp, but then I try to create the helloworld.ear with the following command:

jar cf helloworld.ear web-app.war META-INF

I get an error saying "META-INF: no such file or directory".

Surely someone knows how dumb I'm being. Any help is appreciated.

jar cf helloworld.ear web-app.war META-INF

Had a look at the syntax of jar cf. Here's the syntax:

jar cf jar-file input-file(s)

The command that you are using mentions META-INF as an input file but such a file is not present hence its throwing the error

By default, a META-INF directory is ignored by the jar utility being that it's a special directory in the archive. To tell the jar tool to do what you want execute

jar cvfM helloworld.ear web-app.war META-INF

Use of the 'M' flag shuts the default behavior off. Note, usually people use Ant for this type of stuff being that when you use the above command a MANIFEST.MF file is not generated for you automatically. If you want to use the form above and you required a MANIFEST.MF file, you will have to write/generate it yourself and place it in the META-INF directory.

Note...as previously mentioned, META-INF has to exist ;-)

Yes sorry to have wasted your time fellas but I missed the part where your supposed to create the META-INF directory... DOH!!!

Feel free to give me a cyber slap!

Thanx for the quick response.

No problem. Do take note thought that when you do the jar command, you will have to use the 'M' flag if you want it to take your META-INF directory. So, it's not a total loss ;-)

Will do, thanx.
