I am trying to migrate a web application from MyFaces 1.1 to 2.2.

I basically followed the first steps under Basic Changes from https://stackoverflow.com/a/4532870/5467214 to upgrade from JSF 1.1 to JSF 2.2:

  • update web.xml
  • update faces-config.xml
  • replace old myfaces jars with version 2.2 jars

For the time being, I intend to keep JSP and replace them with Facelets once the first, presumably "painless" steps of just upgrading JSF are successful.

The web application worked with the old JSF version but after doing the steps described above, I get the following error and stack trace:

We use Tomcat7 as a servlet container, IntelliJ Community Edition as IDE and Maven as a build manager and for dependency management.

Since "Tomahawk" appears in the stack trace, I replaced tomahawk-1.1.9.jar with tomahawk21-1.1.14.jar in my /WEB-INF/lib, according to Which jars do I need in order to avoid "NoClassDefFoundError: com/sun/facelets/tag/jsf/ComponentHandler"?. Unfortunately, it didn't solve the problem.

I also couldn't find a tomahawk version specifically for JSF 2.2, neither in the maven repository nor anywhere else.

Would that be necessary to use tomahawk with MyFaces 2.2?

Or does the error stem from something else?

  • Are you sure tomahawk-1.x is not still there somewhere? And check this: at org.jenia.faces.template.handler.ViewHandler.createView(ViewHandler.java:251)... jenia??? And net.sf.jsfcomp.chartcreator.? Commented Apr 12, 2017 at 13:43
  • @Kukeltje Thanks for your response. Yes, I just verified that there is no other tomahawk library in the /WEB-INF/lib directory apart from tomahawk21-1.1.14.jar. I don't know what this jenia taglib is - the joys of inheriting ancient code with the task to update it - but when I remove it I get an error when trying to deploy the webapp on the Tomcat servlet container.

  • The Jenia "dynamic" library that we apparently use comes from jenia.org, and the only two tags that we use from that library are jp:popupFrame and jp:closePopupFrame. Judging by sourceforge.net/p/jenia4faces/bugs/48, I guess there is no JSF2 compatible version of the library. So I will try to remove all usages of these tags, remove the taglib and see if it works. Thanks for pointing this out! Commented Apr 12, 2017 at 14:00
  • @Kukeltje The jenia library was indeed the culprit! After removing it, the error vanished. Thanks again for pointing it out! Commented Apr 12, 2017 at 14:17
  • Soo easy to find if you read the stacktrace... Would have saved you a lot of time posting a question and us time too!!! Please learn from this! Commented Apr 12, 2017 at 14:22

From the stacktrace, I suspect another JSF 1.x specific library causes this:

at org.jenia.faces.template.handler.ViewHandler.createView(ViewHandler.java:251)

So check what the 'jenia' library is and get a newer jsf 2 compatible version or remove it.
