Sorry,my fault!
Just mis-typed "target".Class App is executed successfully this time with
command:C:\my-apps\genapp>java -cp target\test-application-1.0.jar
mdn.testapp.App;
That's what I reckoned ;-)
Does this mean i have to use -cp parameter everytime executing a clas?
The jar has to be on your classpath, yes. Usually one uses some script
to achieve that (*.bat on Windows). Alternatively, you can set the
CLASSPATH environment variable. I recommend reading something like
http://mindprod.com/jgloss/classpath.html
And,I
found it didnt make any difference by setting
"maven.jar.manifest.extensions.add=true"
It's the maven.jar.mainclass attribute that makes sure that the main
class entry is added to the jar's manifest. About the manifest see e.g.
http://java.sun.com/j2se/1.3/docs/guide/jar/jar.html#JAR%20Manifest (the
first doc I found; there might be a newer one).
Try to call the jar with "java jar" then (the jar tool). See e.g.
http://java.sun.com/j2se/1.3/docs/tooldocs/win32/jar.html (the same
comment as above).

The main class is still not found.
Did you type "tartget" (mind the "t") at the commandline? Try it again
with "target".
How does your jar look like? Does App.class sit within mdn/testapp?
Does App.java in your project really reside within src/java/mdn/testapp?

Setting the classpath could also help:
C:\my-apps\genapp\test-app>java -cp target\test-app-1.0.jar
mdn.testapp.App

You probably want to set the maven.jar.mainclass attribute to get the
main class entry written to the jar manifest file. See
http://maven.apache.org/maven-1.x/reference/plugins/jar/properties.html
Here you would call the jar directly:
C:\my-apps\genapp\test-app>java jar target\test-app-1.0.jar
Hi,
I experienced an exception Error while executing the App class of my

Could any body give some advice? where is the fault?
