The configME.jar configuation applet for the Digi Connect ME is signed with the Digi digital ID credentials.  If you rebuild the applet, or provide your own version of the applet with your products, you should sign the jar file with your own digital signature.  The steps listed below show how to request a Java Sun Signing Digital ID from VeriSign.  Replace the Digi name and Minnetonka location with your company's name and location.

1. Download and install Sun JDK
The Sun JDK version 1.4.2 can be found here: http://java.sun.com/j2se/1.4.2/download.html

2. Generate key (and keystore):
C:\j2sdk1.4.2\bin>keytool -genkey -dname "cn=Digi International Inc., o=Digi International Inc., l=Minnetonka, s=Minnesota, c=US" -alias digi -keypass <mypassword> -keystore mykeystore -storepass <mypassword> -keyalg "RSA"

3. Generate certificate request
C:\j2sdk1.4.2\bin>keytool -v -certreq -alias digi -file certreq.cer -keystore mykeystore

4. Certificate request (jcertfile.cer)
-----BEGIN NEW CERTIFICATE REQUEST-----
[...]
-----END NEW CERTIFICATE REQUEST-----

5. Request certificate from VeriSign.
- Go to http://www.verisign.com
- Select Code Signing IDs
- Select VeriSign Code Signing Digital IDs
- Select Sun Java Signing Digital ID
- Click Buy Now button

6. Import certificate into keystore
C:\j2sdk1.4.2\bin>keytool -import -trustcacerts -alias digi -file mycert.cer -keystore mykeystore

Note: The machine used to request the certificate and the machine used to retrieve the certificate must be the same.
