Question

I have manually added some class files in jar. and replaced in server. But server didn’t come up with this new jar saying : java.lang.SecurityException: class “test.TestProcess2″‘s signer information does not match signer information of other classes in the same package.

Do i need to sign the jar after updation and how to do the same.

Thanks in advance

Answer 1

Yes.

You can also sign the jar manually for the command line. For example, in windows it looks moreless liek that:

"{YOUR_JDK_INSTALL_PATH}\bin\jarsigner.exe" -verbose -keystore {YOUR_KEYSTORE_PATH} -storepass {YOUR_STORE_PASS} -keypass {YOUR_KEY_PASS} {JAR_FILE}
