When attempting to wrap an APK via the MAA web portal the following error is received:
<Please see attached file for image>
Reviewing catalina.out shows
Step 4 of 4: Signing APK with dummy certificate.
jarsigner: unable to sign jar: no response from the Timestamping Authority. When connecting from behind a firewall an HTTP or HTTPS proxy may need to be specified. Supply the following options to jarsigner:
ERROR: jar signing failed...
ERROR: Exiting, Signing APK failed!
jarsigner attempts to connect to the time stamping authority (TSA) in order to add a timestamping block to the signed jar. This allows an application to be accepted by Java Plugin in a future time when the signer's certificate already expires.
Manually wrap the apk and use the switch -t
"./wrap.sh -a <app_name.apk> -p <PlistName.plist> -t"
This tells the wrapper not to use the TSA for Jar signing.
