java.io.IOException: cannot verify signature block file META-INF/MYKEY

user2170541Nov 15 2013

Hello,

i have a serios problem in my company.

I developed javaws aplication running since years and now we have starting problems with actual java, it brings security warnings. This warning says this application will be blocked in further releases.

The app is signed with an old java 6 jarsigner.  If I sign the jar files of the app with java 7 u45 or u40, I receive the following exception by webstart :

java.io.IOException: cannot verify signature block file META-INF/MYKEY

do somebody have an idea what I could try to do to solve this problem?

I create the keystore  on the follwoing way: C:\Programme\Java\jdk1.7.0_45\bin>keytool -genkey -keyalg RSA -alias MYKEY -keystore fspKeys -storepass xxxxxxxx
