Verify jad signature

Because midlet signing works a little bit differently, you need to use jadtool to verify the signature:

java -jar %wtk_home%/bin/jadtool.jar -showcert -certnum 1 -inputjad myJadFile.jad

Output of this will be something like:

Subject: C=US, ST=CA, L=Santa Clara, O=dummy CA, OU=JCT, CN=thehost
Issuer : C=US, ST=CA, L=Santa Clara, O=dummy CA, OU=JCT, CN=thehost
Serial number: 3d3ece8a
Valid from Wed Jul 24 08:58:02 PDT 2002 to Sat Jul 21 08:58:02 PDT 2012
Certificate fingerprints:
MD5: 87:7f:5e:64:c8:dd:b4:bf:35:39:76:87:99:9b:68:82
SHA: 9d:c0:88:ce:08:83:cd:e6:fe:13:8b:26:f6:b4:df:e2:da:3c:25:98

To show all certificate details:

java -jar %wtk_home%/bin/jadtool.jar -showcert  -all -inputjad <input_jadfile>
