Problem Installing Applet

Question

Hello. Having a little problem installing my applet. The package loads cleanly, but when I try to install the applet it blows up and returns an OP.error.E6.6A86. I looked this up and found out that it means SW_INCORRECT_P1P2. After looking at my code for the longest time, I can't figure out why this error would be thrown. I throw the error in my process method, but can't understand where it would come from in the install or constructor. Any help figuring this out is greatly appreciated. Thanks. Justin
My code:
package test.justin2;
import javacard.framework.*;

&nbsp&nbsp&nbspprivate byte[] userType = {(byte)0x45,(byte)0x4D,(byte)0x50};
&nbsp&nbsp&nbspprivate byte[] password = {(byte)0x50,(byte)0x41,(byte)0x53,(byte)0x53,(byte)0x57,(byte)0x4F,(byte)0x52,(byte)0x44};

Answer 1

Thanks for the help. I tried sending the 0C to make the applet selectable and then received a 0x6A81, SW_FUNC_NOT_SUPPORTED. I didn't have the select or deselect methods in my applet, so I added those also and then received the same error. So what I currently have is the previous code plus this:
&nbsp&nbsp&nbsppublic boolean select()
&nbsp&nbsp&nbsp{
&nbsp&nbsp&nbsp&nbsp&nbsp&nbspreturn true;
&nbsp&nbsp&nbsp}
&nbsp&nbsp&nbsppublic void deselect()
&nbsp&nbsp&nbsp{
&nbsp&nbsp&nbsp&nbsp&nbsp&nbspreturn;
&nbsp&nbsp&nbsp}
I can't help but think it's got to be some little thing, because it looks fine to me. I greatly appreciate the help. Justin.
