Lucee 5 Upgrade Failed

[Cody W]

Hello,

We're attempting an upgrade from "Lucee 4.5.2.018 final" to Lucee 5 by following the directions in the documentation at http://docs.lucee.org/guides/lucee-5/upgrading-lucee-45.html. 

The upgrade seems successful, and Lucee starts as expected. However, visiting a website or the Lucee admin results in the same error. 

lucee.commons.lang.ClassException

cannot load class through its string name, because no definition for the class with the specified name [org.gjt.mm.mysql.Driver] could be found caused by (java.lang.ClassNotFoundException:org.gjt.mm.mysql.Driver not found by lucee.core [64];java.lang.ClassNotFoundException:org.gjt.mm.mysql.Driver;)

I've attached a full error page as "lucee.commons.ClassException.html". After seeing this error, I copied over the "mysql-connector-java-bin.jar" file to the lib directory, and the above error message went away.Unfortunately, I still couldn't access any of my Lucee admin pages. The error message was "Lucee 5.0.1.85 Error (missinginclude)". I've attached a stack trace as "lucee_admin_stacktrace.txt".

I've also attached the relevant entries from the Catalina log as "relevant_catalina.txt".

Here's some general info from the Lucee Overview.

Hi Cody,

When you say you "followed the instructions", did you follow them exactly, particularly the part stating "Remove all other JARs in the same directory..."? 

Lucee 5 works completely differently to Lucee 4 when it comes to the external dependencies and leaving the previous JARs around, or copying them back as have suggested you have done, will cause you problems. 

Also, did you download the "lucee.jar" file from here:

http://stable.lucee.org/download/?type=releases

the link to the current release lucee.jar file is:

http://release.lucee.org/rest/update/provider/loader/5.1.1.65

The file it downloads is 63.5Mb. The file contains all the extensions for DB, cache, etc... that were previously bundled. From the error message, it looks like you are missing the MySQL extension, so I wonder if you got the wrong file.

The only other thing I would say, is from your output, you appear to be on a pretty old version of Java 7, which I believe there have been lots of security updates for since, so I would recommend you upgrade to the latest version of Java 8.

Kind regards,

Andrew

Hi Andrew,

Thanks for taking a look! Yes, all other JARs were removed from the lib directory. I heard that Lucee 5 includes all dependencies in the one JAR, which is why I'm so bewildered at the current situation. I've done a few in place Lucee 4.5 to Lucee 5 upgrades, and I've never ran into this issue.

I updated Lucee to use the latest Java 8 JDK from Oracle, as you suggested.

At first I was using "lucee-5.0.1.85.jar", but I just tried updating with the latest JAR from the link you provided, while using Java 8, and I got the same error message.
