I have recently came up with a deployment Exception of my web application (after receiving some changes from the SVN Repository) that said:

< Error > < Deployer > with ID ‘1350377960779’ for task ‘1’. Error is: ‘com.rsa.jsafe.JSAFE_PaddingException: Could not perform unpadding: invalid pad byte.’

Answer 1

Googling to find an answer was not very helpful. After examining the files received from my SVN repository, i noticed that a jdbc application resource was changed.

Examining the jdbc resource more closely i found that it was using the password-encrypted property which is used only for production environments

<password-encrypted>{AES}some+very+long+encrypted+string</password-encrypted>

So I commented out this property and used the property used for the development environment:

 <properties>
     <property>
        <name>user</name>
        <value>MY_USER</value>
     </property>
     <property>
        <name>password</name>
        <value>MY_PASS_IN_PLAIN_TEXT</value>
     </property>
  </properties>

And that worked just fine.
