executing jar file

[Duane Riech]

I created a jar file for my server. When I try
to execute it in a RANDOM directory, i.e.
C:\, I get the error. Class RegFBNSDatabase starts
the rmiregistry and it's in the jar file.
C:\> dir *.jar

Thanks

[Mark Spritzler]

And you class RegFBNSDatabase is where the
public static void main(String[] args)
is located?
Mark

[Duane Riech]

Yes. RegFBNSDatabase starts the rmiregistry and
does have a main. The jar -tvf runserver.jar
listing shows the RegFBNSDatabase.class file in
suncertify/db directory, yet it says it's the
wrong name.
I don't get it.
Thanks

[Samual Harvey]

I would check the following:-
1. How I created the jar file, I mean what was the classpath set when I created the jar file and the source directory for the java files given to the jar utility.
2. Make sure the manifest file has correct entry for the main class file i.e package and class name.
3. If this is good then check the version of the jar utility.
Thanks.

[Duane Riech]

Here's the manifest file.

C:\project>type serverManifest.txt
Main-Class: suncertify.db.RegFBNSDatabase

It DOES have a <CR> at the end of the line.
How should/would a classpath be specified when
making the jar file.
I've looked at serveral examples in java manuals,
according to them it's right.

[Samual Harvey]

I see that you are using manifest.txt instead of manifest.mf file and is missing the following lines:-
Manifest-Version: 1.0
Created-By: 1.x.x (Sun Microsystems Inc.)
where x is the version of sun jdk that u use.

[Mark Spritzler]

Yeah, what Samuel said. Sometimes you can miss the obvious.

[Duane Riech]

Here's my new manifest file (renamed):

serverManifest.mf

Main-Class: suncertify.db.RegFBNSDatabase
Manifest-Version: 1.0

I just don't understand what it means by "wrong name".

Thanks,

[Samual Harvey]

Based on what you have said above I am assuming that you have a folder suncertify under project directory. If not then copy the suncertify folder under project.
Then try using the following command :-
c:\project>set classpath=c:\.
C:\project>jar -cvfm runserver.jar serverManifest.mf project\suncertify\ .
Let me know if this works.
Thanks.

[Duane Riech]

Thanks,
Yes, my directory structure is:
C:\project\suncertify\db
All of the .class files are in the project\suncertify\db directory.

I tried it, it didn't work.
Here's the output.
C:\project>set classpath=c:\.

C:\project>

I just noticed a error message at the start of creating the jar file:
C:\project>jar -cvfm runserver.jar serverManifest.mf project\suncertify\ .
project\suncertify : no such file or directory

So I changed the jar command to
jar -cvfm runserver.jar serverManifest.mf c:\project\suncertify .

But I got the same error.

Thanks,

This is strange. I hope you have already checked what is inside RegFBNSDatabase.java. It should have first line as :-
package suncertify.db;

[Duane Riech]

No, the top level (main) code was NOT part of the
suncertify.db package. But that wasn't the problem afterall.....
I had compiled the .java files in another, original, code testing directory. I had built the C:\project\suncertify\db directory structure just to create the .jar files I would need for submission and then COPIED the .class files into the appropriate subdirectory. I guess you can't do that. I had to build under the project subdirectory, with my classpath set to c:\project, then create my jar file. Then it would run.

BUT, if I take the jar file, copy it to, say, the c:\ directory, set my classpath to c:\ then run it, it will run, HOWEVER, I still have a problem.
By design requirements, I have to open the db.db file. Is there a way to force the
application to use the .jar copy of the file. But that wouldn't work anyway since it's probably compressed. Or can you?
If I can't use the .jar version of the file, then that forces the user to expand the jar file back onto the user's file system... right? And if they have to do that, why not give instructions to run the application in the normal way?

How have successfult SCJD candidates done it???
Thanks,
