I am trying to load jar file using JCL using following code
FileInputStream fis = new FileInputStream(new File( "C:\\Users\\sunils\\glassfish-tests\\working\\test.jar") );
JarClassLoader jc = new JarClassLoader( );
jc.add(fis);
Class main = jc.loadClass( "highmark.test.Main" );
String[] str={};
main.getMethod("test").invoke(null);//.getDeclaredMethod("main",String[].class).invoke(null,str);
fis.close();
But when I try to run this program I get Exception as
Exception in thread "main" java.lang.reflect.InvocationTargetException

According to this it is not able to locate class, But when I run the jar file explicitly it runs fine. It seems like JCL is ignoring other classes present in the jar file,
MANIFEST.MF file in jar file shows:
Manifest-Version: 1.0
Class-Path: .
Main-Class: highmark.test.Main
It seems to be ignoring Class-Path: . , This jar file runs fine when I run it using Java explicitly, This is just a test, in reality this jar file is coming as a InputStream and it cannot be stored in filesystem, How can I overcome this problem , Is there any workaround ?
Thanks for any help .
UNDATE:
Here is a jar Main class :
package highmark.test;
import org.glassfish.api.embedded.*;
import java.io.*;
import org.glassfish.api.deployment.*;
import com.sun.enterprise.universal.io.FileUtils;
public class Main {
public static void main(String[] args) throws IOException, LifecycleException, ClassNotFoundException {
test();
}
public static void test() throws IOException, LifecycleException, ClassNotFoundException{
Server.Builder builder = new Server.Builder("test");
Server server = builder.build();
server.createPort(8080);
ContainerBuilder containerBuilder = server.createConfig(ContainerBuilder.Type.web);
server.addContainer(containerBuilder);
server.start();
File war=new File("C:\\Users\\sunils\\maventests\\simple-webapp\\target\\simple-webapp.war");//(File) inputStream.readObject();
EmbeddedDeployer deployer = server.getDeployer();
DeployCommandParameters params = new DeployCommandParameters();
params.contextroot = "simple";
deployer.deploy(war, params);
}
}
