error while building a project in netbeans

[jainshasha]

hi guys

actually i try to build someone else project through netbeans
so it gives the output shown below

init:

deps-jar:

Compiling 3 source files to C:\Documents and Settings\Zoomi\My
Documents\NetBeansProjects\JpxxMailServer\build\classes

Note: .....\NetBeansProjects\JpxxMailServer\src\org\jpxx\mail\JJ.java
uses or overrides a deprecated API.

Note: Recompile with -Xlint:deprecation for details.

compile:

Building jar: .....\NetBeansProjects\JpxxMailServer\dist
\JpxxMailServer.jar

Copy libraries to ......\NetBeansProjects\JpxxMailServer\dist\lib.

To run this application from the command line without Ant, try:

java -jar "......\NetBeansProjects\JpxxMailServer\dist
\JpxxMailServer.jar"
jar:

BUILD SUCCESSFUL (total time: 3 seconds)


and makes a jar in the /dist folder which on executing that jar file
make these two exceptions

"A Java Exception Occured"

"Error : Could not find the main class "
"Error : A JNI error has occured, please check your installation and
try again"

although i have made the file in which i define the main class


so check out this and help if someone knows

What file is main in? What package is it in?
Where do you save the jar file?
Do you have your CLASSPATH set properly?
What command are you using to execute?

What file is main in? What package is it in?
Where do you save the jar file?
Do you have your CLASSPATH set properly?
What command are you using to execute?

main file is in JJ.java
external jar files are stored in \lib
executing through command line i use
java -jar ".....\NetBeansProjects\JpxxMailServer\dist
\JpxxMailServer.jar

Does the JAR manifest specify the 'Class-pPath:' to the external JARs?

Does the JAR manifest specify the 'Class-pPath:' to the external JARs?

Class-Path: lib/commons-dbcp-1.2.2.jar lib/commons-pool-1.3.jar lib/dn
sjava-2.0.5.jar lib/jdom.jar lib/JMSConsole.jar lib/log4j-1.2.15.jar
