i create jar file of Swing_Test.java and call this Applet at JSP like this.

<APPLET code="Ex_Applet.class" archive="abc.jar" WIDTH="400" HEIGHT="16">

</APPLET>

thanks for reply and giv some more solutions....

thanks again

It doesn't matter how many Java files you have. You need to add all your class files into a jar and sign it.

In order for an applet to get high privilege, all the classes it calls must be trusted, which means either it's in a signed jar (your own classes), or it's part of the JRE (the Swing classes...)

This is OK, your key is created by yourself and not confirmed by VeriSign or other big CA. Hence the browser cannot authenticate it.

Can you open the Java console (possibly from browser's tool menu) first and post the full error message?

"java.lang.Exception: java.lang.SecurityException: class "Swing_Close$2"'s signer information does not match signer information of other classes in the same package"Are you using extra jars? or you have both jar and bare class files in your classpath?

> java.lang.NullPointerException

> at Swing_Close.<init>(Ex_Applet.java:117)

You have a null pointer at line 117 of a file called Ex_Applet.java, in the initialization or construction of a class called Swing_Close.

You don't need to ask on forums for this sort of information, you already had it.
