Could not initialize class javax.crypto.SunJCE_b

I have a Java servlet application developed and on my develpment PC everything works as expected including using SFTP programmatically to copy over a PDF using HTTPS on port 8443 etc and with SSL certificates in place too.

However, when I attempt to run the application on the Live server I receive the error;

java.lang.NoClassDefFoundError: Could not initialize class javax.crypto.SunJCE_b

On investigation, some are suggesting check the jce.jar. But I have ensured the jce.jar is present and also created a "lib" folder in my project and copied the jar there and placed the jar on my build path but still the problem exists.

How do I resolve this please? Thanks in advance. Here is the console output from right after Tomcat has started the application;

I've seen this problem pop up very often and there seems to be a lot of confusion around it. The actual reason this is happening is because the JRE you are using to run your application has been set up with the unrestricted JCE policy jars inside its jre/lib folder (inside your jdk install folder).

If your current project does not need these, then you can move then out of this folder temporarily. This will remove the requirement on the jce libraries and you will no longer see this error.

Hope this helps.

The jce.jar must be inside the folder WEB-INF/lib of the deployed web application.
