Re: MyFaces / Tomahawk / Tiles (NoClassDefFoundError)

Mon, 22 Dec 2008 23:47:36 -0800

Resolved! Seems that JspTilesViewHandlerImpl was looking for a class which only exists in tiles 1.x. Thanks for your help M; you not only helped me solve my problem, but helped me learn how to troubleshoot. :-) Below is how I fixed it (so future users can look it up instead of asking).
I have the files in a lib folder and they're set up in the Netbeans project to be copied to WEB-INF/lib when the project is deployed. I tried copying them to the $tomcat-install-dir/lib which didn't make any difference (I thought parhaps they had to be loaded to do the deployment). 


I checked in tiles-core-2.0.4.jar and found 
org.apache.tiles.definition.Definitions[[Factory]Exception].class



The last thing which is called in the stacktrace is 
org.apache.myfaces.config.FacesConfigurator.getApplicationObject() so I 
think the problem might actually be with 
org.apache.myfaces.tomahawk.application.jsp.JspTilesViewHandlerImpl 
(since that's the class listed in my web.xml).  I checked out the 
tomahawk jar file and found that, inaddition to 
JspTilesViewHandlerImpl.class, there was another class in the same 
package named JspTilesTwoViewHandlerImpl.class.  Since I'm using Tiles 
2.0.5, I figured this class which I haven't seen referenced anywhere on 
the Internet was worth a shot.  I changed my faces-context.xml as such:

       <application>

           
<view-handler>org.apache.myfaces.tomahawk.application.jsp.JspTilesTwoViewHandlerImpl</view-handler>

       </application>


I shut down tomcat and started it back up and my application 
successfully deployed.  It complained that I didn't have jstl support, 
but a quick download and that seems to be resolved.  I still have some 
errors to work out, but they seem to be unrelated to myfaces or tiles.  
I appreciate the (very speedy) help.


Sincerely,
Adam

NoClassDefFoundError - This means that the class is found but some dependency 
is not found or there is a conflict. Make sure that all dependent jar files are 
present only once on the classpath.

Thanks,

Same results.  Thanks for the quick response though.

You might want to register the listener in web.xml:

<listener>
        
<listener-class>org.apache.myfaces.webapp.StartupServletContextListener</listener-class>
</listener>

I'm having some trouble understanding how to get Tiles working.  I 
followed the directions on this page:

http://myfaces.apache.org/tomahawk/tiles.html


Now I've managed to prevent my project from deploying.  Here's the 
stacktrace I get when I try to deploy:

This is my faces-config.xml:

    <application>

        
<view-handler>org.apache.myfaces.tomahawk.application.jsp.JspTilesViewHandlerImpl</view-handler>

    </application>
</faces-config>

and web.xml contains this:
<context-param>
    <param-name>tiles-definitions</param-name>
    <param-value>/WEB-INF/tiles.xml</param-value>
</context-param>


Since I don't think it gets far enough to read the tiles.xml file, I'll 
refrain from posting it and cluttering up this e-mail any further.



I'm using Tomahawk-1.1.8, myfaces-1.2.5, and tiles 2.0.5 
(tiles-api-2.0.5.jar, tiles-core-2.0.5.jar, tiles-jsp-2.0.5.jar).  I 
don't particularly want struts, I really just want the tiles support; 
but if including all of struts is the only answer, then so be it.  I've 
checked the mailing list, but I could only find things related to JBoss 
and I/O errors.  The three pages of google results which came up did not 
explain the cause of, nor solution to the exception which is being 
thrown.  I'm posting the question on this list because I'm following the 
guide from myfaces.apache.org.  If this is more of a question for the 
struts mailing list, please let me know.


Thank you,
Adam
