java.lang.SecurityException signer information does not match signer informati

Flavio FONTANELJul 10 2025 — edited Jul 10 2025

Hi i have two jar file

KeyPressed.jar

frame.jar

when i try to load a form 12.1.2.3. version it gives me this error

java.lang.SecurityException: class "oracle.forms.fd.KeyPressedTextField"'s signer information does not match signer information of other classes in the same package

I have tryed to delete manifest in both of them and re-sign with sign_webutil.bat (autogenerate sign)

After I restart from EM wls_form and WLS_REPORT..but it always gives me that error…

I ‘ve tryed to understand using jarsigner -verify -verbose …but while the keyPressed.jar it’s good ..the others says :

C:\Oracle_12C\Middleware\Oracle_Home12C\forms\java>jarsigner -verify -verbose frame.jar
