But my app uses 50 jar file
do i need to add jar separatelyYes.
and do i need to sign each jar ??Yes. Beware if you're using third-party jars, some of them may already be signed. In that case, you have to build a jnlp file for each different signature and add a reference of the file to the main jnlp file. For the jars you're signing yourself, you may referenced them in the main jnlp file. They must all have the same signature than the main jar.
Here's an example using Javamail ( the jar is already signed by the manufacturer ) :
In the main jnlp :
         <jar href="MyApp.jar" main="true"/>
            <extension name="Java Mail" href="mail.jnlp"/>
            <jar href="Other.jar"/>
The mail.jnlp content :
<?xml version = '1.0' encoding = 'utf-8'?>
    <jnlp spec="1.0+" codebase="file:///D:/Build/" href="mail.jnlp">
     <information>
            <title>JavaMail</title>
         <vendor>Sun Microsystems, Inc.</vendor>
     </information>
     <security>
            <all-permissions/>
     </security>
        <resources>
            <jar href="mail.jar"/>
        </resources>
        <component-desc/>
    </jnlp>
