Not able to execute a class with external class path

Question

I have a class Test.java

import com.sun.star.bridge.XUnoUrlResolver;
import com.sun.star.comp.helper.Bootstrap;
import com.sun.star.lang.XMultiComponentFactory;
import com.sun.star.lang.XMultiServiceFactory;
import com.sun.star.uno.UnoRuntime;
import com.sun.star.uno.XComponentContext;

public class Test {



    XMultiServiceFactory ooConnect() {

        final String sConnectionString = "uno:socket,host=localhost,port=8100;urp;StarOffice.ServiceManager";
        // create the initial component context
        XComponentContext rComponentContext = null;
        try {
            rComponentContext = Bootstrap
                    .defaultBootstrap_InitialComponentContext();
        } catch (Exception e2) {
            // TODO Auto-generated catch block
            e2.printStackTrace();
        }

        // retrieve the servicemanager from the context
        XMultiComponentFactory rServiceManager = rComponentContext
                .getServiceManager();

        Object objectUrlResolver = null;
        try {
            objectUrlResolver = rServiceManager.createInstanceWithContext(
                    "com.sun.star.bridge.UnoUrlResolver", rComponentContext);
        } catch (Exception e1) {
            // TODO Auto-generated catch block
            e1.printStackTrace();
        }

        // Create a new url resolver
        XUnoUrlResolver xurlresolver = (XUnoUrlResolver) UnoRuntime
                .queryInterface(XUnoUrlResolver.class, objectUrlResolver);

        XMultiServiceFactory rOfficeServiceManager = null;
        try {
            // resolve the uno-url
            Object objectInitial = xurlresolver.resolve(sConnectionString);

            rOfficeServiceManager = (XMultiServiceFactory) UnoRuntime
                    .queryInterface(XMultiServiceFactory.class, objectInitial);
        } catch (Exception e) {
            e.printStackTrace();
            return rOfficeServiceManager;
        }
        return rOfficeServiceManager;
    }




    public static void main (String [] args)

    {
        Test test = new Test();

        XMultiServiceFactory serviceFactory = test.ooConnect();
        if(serviceFactory != null)
        {
            System.out.println("YEYEYEYEY");
        }
    }
}

why I try to compile this I use this command

javac -cp java_uno.jar;juh.jar;jurt.jar;ridl.jar;unoil.jar Test.java

it successfully compiles and give me a class.

but When I try to execute the class with below command

java Test, I get below error

Exception in thread "main" java.lang.NoClassDefFoundError: com/sun/star/comp/helper/Bootstrap
        at Test.ooConnect(Test.java:18)
        at Test.main(Test.java:64)
Caused by: java.lang.ClassNotFoundException: com.sun.star.comp.helper.Bootstrap

        at java.lang.ClassLoader.loadClass(ClassLoader.java:358)
        ... 2 more

or if I use this command

java -cp .:java_uno.jar;juh.jar;jurt.jar;ridl.jar;unoil.jar Test

I get this error Error: Could not find or load main class Test

any help will be appreciated.

as suggested I changed the run command to

java -cp .;java_uno.jar;juh.jar;jurt.jar;ridl.jar;unoil.jar Test

now I get this exception

Exception in thread "main" java.lang.UnsatisfiedLinkError: no juh in java.library.path

Answer 1

On Windows class separator in classpath is semicolon (;). For UNIX it is colon (:). You are using both separators in one command line:

java -cp .:java_uno.jar;juh.jar;jurt.jar;ridl.jar;unoil.jar Test

Since your compilation was good I assume you are on Windows. So, use semicolon for whole path:

java -cp .;java_uno.jar;juh.jar;jurt.jar;ridl.jar;unoil.jar Test
