Error executing a .jar file with JDBC SqlServerDriver

[mikel lertxundi via JavaKB.com]

I've a problem executing a .jar file when it invokes the Sql Server Driver.
I've no problem inside the IDE (Eclipse) but when I deploy it to a jar file
and execute it from the console I got this:
(Not to say that I've modified the classpath with the jar libraries of the
driver from Microsoft)

Hi,

Sorry but the classpath IS the problem with such an exception.

What is the exact commands you us on the console ?

Regards,

Arnaud

I use java -jar myFile.jar

thanks

[mikel lertxundi via JavaKB.com]

Excuse me,

and to set the classpath:

set classpath = pathForJarFile/DriverFile.jar

[Arnaud Berger]

Hi,

Try this: java -cp "list of jar paths" -jar myFile.jar

If you are running linux, it may simply be a matter of using "export"
instead of "set"
Also note that CLASSPATH variable is case-sensitive with linux.
Check this with "echo $CLASSPATH" when you're done

Arnaud

Sorry I'm wondering if the command I told you would work.

I think calling "java -jar" may not take CLASSPATH into account.

So better use :

java nameOfYourMainClass

once your CLASSPATH was correctly set (including myFile.jar)

Arnaud

Alternatively add the following line into your manifest file:

Class-Path: . jar1.jar jar2.jar jar3.jar

jar1.jar jar2.jar jar3.jar should be located in the same directory where
you're running your application from. "." is redundant if you are not
using any classes or files that aro not bundled into jar files.

Best regards,
Igor.

I've done all you say with no results, I dont know what to do.

I've try executing the jar file using command java mainclass like this

java mainclass.class

and I have this answer: Exception in thread "main"
java.lang.NoClassDefFoundError: principal/class

so...it doesn't work (or I'm doing it wrong).

Neither the command java -cp "list of jar files" works. I type it like this:

java -cp jarfile1;jarfile2;.. -jar myjarFile.jar

Just one last thing:

In my code I type this:

System.out.println("Class path is really " + System.getProperty
("java.class.path") );

to watch the real classpath that is managing the aplication, and I obtain
that the jar file is really the class path.

Class path is really prueba.jar

where prueba.jar is the jar file that I've develop.

Thanks for all

Mikel

He actually ment here:

java -cp jarfile1;jarfile2;.. mainclass.class

including your own jar file in -cp.

Best regards,
Igor.

Hi,
I did what you say typing,
java -cp jarfile1;jarfile1 MyMainClass.class and I got:

Exception in thread "main" java.lang.NoClassDefFoundError: principal

Mikel

[Arnaud Berger]

Hi again ,

1) You shouldn't include the ".class" part, your command should look like :
java -cp jarfile1;jarfile1 MyMainClass

and not

java -cp jarfile1;jarfile1 MyMainClass.class

2)If your class is in a package (say mypackage) , the command would be

java -cp jarfile1;jarfile1 mypackage.MyMainClass

Hope it helps,

Regards,

Arnaud

I'm sorry that you've gotten some bad advice here. However, you need to post what you
actually enter at the commandline.

Try this first:

java -cp "pathForJarFile/DriverFile.jar;prueba.jar" Principal

Assuming:

+ prueba.jar is in the current directory, otherwise use the proper path.
+ prueba.jar contains Principal.class.
+ 'pathForJarFile' is the path to the driver jar.
+ 'DriverFile.jar' is the jar containing the JDBC driver.
+ 'Principal' is the actual name of your class containing main().
+ The Principal class is not in a package.

Again, please post *exactly* what you are entering at the command line and the results
you get.

Thank you very much to all, now it works.

It was a just a f***ing classpath thing
