The Java Cryptography Extension (JCE) Unlimited Strength Jurisdiction Policy Files are a required component for Java LiveUpdate to run with Scan Engine/ Symantec Protection Engine
Java LiveUpdate may exhibit abnormal behavior without the JCE installed.
Symptoms
Download the needed JCE according to the JAVA JRE version installed
Example: Download JCE6 if you have JRE6 installed.
1. Compare policy file sizes
The policy files with the JCE are slightly different than the ones included with Java.
Compare the policy file sizes of what is downloaded from Oracle to those in the Java lib folder to the ones downloaded with the JCE. If the sizes are not the same the JCE is not installed.
Example for JRE6:
2. Compare MD5 hash of the policy files.
Compare the policy file hashs values (MD5, SHA1, CRC32, etc) to those from the JCE. The JCE policy file size and hash data is not published here because it may change when Oracle updates Java or releases a new JCE.
3. Check liveupdt.log file
The liveupdt.log file contains the following lines:
<date & time> IdsEncodingFailed
<date & time> IdsCheckJCEPolicyFiles
<date & time> IdsEncodingFailed
<date & time> IdsCheckJCEPolicyFiles
The above is an indication the JCE files are missing.
