Get files from Jar which is on the repository without downloading the whole Jar from Java

I would like to access the jar file on the repository, search inside it for the certain files, retrieve those files and store them on my hard disc. I don't want to download the whole jar and then to search for it.

So let's assume I have the address of the Jar. Can someone provide me with the code for the rest of the problem?

public void searchInsideJar(final String jarUrl, final String artifactId,

        final String artifactVersion) {

    InputStream is = null;

    OutputStream outStream = null;

    JarInputStream jis = null;

    int i = 1;

    try {

        String strDirectory = "C:/Users/ilijab/" + artifactId   +artifactVersion;



        // Create one directory

        boolean success = (new File(strDirectory)).mkdir();

        if (success) {

            System.out.println("Directory: " + strDirectory + " created");

        }



        is = new URL(jarUrl).openStream();

        jis = new JarInputStream(is);



        while (true) {

            JarEntry ent = jis.getNextJarEntry();

            if (ent == null) {

                break;

            }

            if (ent.isDirectory()) {

                continue;

            }

            if (ent.getName().contains("someFile")) {

                outStream = new BufferedOutputStream(new FileOutputStream(

                        strDirectory + "\\" + "someFile" + i));

                while(ent.)

                System.out.println("**************************************************************");

                System.out.println(i);

                i++;

            }

        }

    } catch (Exception ex) {

    }

}

So, in upper code, how can I save the file I found(the last if) into directory.
