Migrating PF 13 app from Tomcat 8.5/JDK11 to Tomcat 10.1/JDK17

[xidbhonaker]

I have a working website app on PF 13.0.4, MyFaces 2.3.1, Tomcat 8.5 and Java 11. I need to migrate Tomcat and Java to Tomcat 10.5 and Java 17. I first tried migrating to MyFaces 3.4.0, made appropriate import statement changes and built. But when Tomcat starts I get this error:

TldScanner#scanJars;At least one JAR was scanned for TLDs yet contained no TLDs

I then tried going back to MyFaces 2,3,1, and that didn't help, although I get an exception at JVM startup:

java.lang.IllegalStateException: Error starting child:
...
Caused by: java.lang.ClassNotFoundException: javax.servlet.ServletContextListener

So this is apparently something lookng for the javax-based Servlet but 10.1 has the jakarta-based servlet. It's not clear in the stack trace if this call was in myfaces or in primecode.

Is there a magic sauce here to get the right PrimeFaces and MyFaces versions for Tomcat 10.1?

Tomcat 10.1 is jakarta, MyFaces 3,4 and 4.1 is jakarta

you need to adjust all your code and also check all configs; javax is gone

@xidbhonaker if you are looking for a quick way to upgrade your project to Jakarta check out: https://www.melloware.com/java-ee-6-8-to-jakarta-ee-10-upgrade/ i have modified and OpenRewrite script that with one command does 90% of the work for you.

Thanks, tandrashcko, I've done a lot based on your suggestions, but still seem to be having an issue.

Assuming by "MyFaces 3, 4" you mean either version 3 or 4 of MyFaces, as I don't find a 3.4 version.

Based on that, I have cleaned out all javax, but still get errors. Pertinent errors from the log:

I'm using the bundle in myfaces-bundle-3.0.2.jar.

I'm using the bundle in myfaces-bundle-3.0.2.jar.

This would insinuate that the primefaces-13.0.4 jar file still has a reference (in org.primefaces.webapp.UploadedFileCleanerListener) to the javax (not jakarta) servlet classes. I have no javax remaining in my source or in any config files, and I get clean compiles from the JDK 17 javac compiler.

Any suggestions?

You need the Jakarta Version of primefaces

[xidbhonaker]

tandrashko,

Thanks. As I mentioned at the beginning of my original post, I am using PF 13.0.4, and the website isn't much help in figuring out versions to match with JDK and JSP verions. Do you know which primefaces version 13 is the jakarta one? I'd prefer not to try to go to 14 if I can avoid it in order to keep the migration effort as small as possible.

tandrashko,

I tried using 13.0.10 and 14.0.10. No difference.

Also, I noticed the problem seems to be happening in org.primefaces.webapp.UploadedFileCleanerListener. My app doesn't have file upload logic; in fact, I searched the entire project (source files) for the word 'Upload' and it's not there.

@xidbhonaker did you check this post : https://stackoverflow.com/a/66509057

Make sure you are adding the classifier.

[melloware]

Just check here every release has notes https://github.com/primefaces/primefaces/releases

[xidbhonaker]

Thanks, melloware. No impact on anything in our app. Will hold on .10.

Without Maven, the 'classifier' is just in the URL for the download. On the README file, for example, the JAR link value is "https://search.maven.org/remotecontent?filepath=org/primefaces/primefaces/14.0.10/primefaces-14.0.10.jar". I changed the filename at the end of the URL to primefaces-14.0.10-jakarta.jar

Your help is greatly appreciated!

Melloware,

I'm old school and am not using Maven.

Another post in the github discussions (https://github.com/orgs/primefaces/discussions/1264) tells me there may be a different jar file. I found the download links in the README file at https://github.com/primefaces/primefaces?tab=readme-ov-file, where it only has one download per version. How do I get the 'jakarta' version without Maven?

[melloware]

You can download it from here: https://repo1.maven.org/maven2/org/primefaces/primefaces/14.0.11/

That lists all the jars for download.

[xidbhonaker]

melloware,

I had taken a 'hail mary'; copied the link from github download and added '-jakarta' prior to .jar. Found both 13.0.10 and 14.0.10. github didn't know about .11 (as a contributor you know more than we do!

Once I used the primefaces-14.0.10-jakarta.jar file from github, the app came up as it should!

Where might I find the release notes for 14.0.11 to determine if I should opt for that version?

Thanks for your help.
