Error when deploying ICEFaces portlet

[Michael Poznecki，修改在14 年前。]

Hello all,
when I deploy my ICEFaces portlet I receive the following error:

INFO: Undeploying context [/iceFaces-attempt-portlet]
20:39:57,727 INFO  [PortletHotDeployListener:333] Unregistering portlets for iceFaces-attempt-portlet

Does anyone know why at the last moment it will say "startup failed due to previous errors"? I did not see any previous errors.

Thanks,
Michael

Hi Michael,
I'm getting same error too, trying to deploy sample-icefaces-jsf-1.2-sun-facelets-portlet-5.2.1.1 on Liferay 5.2.3. Doesn't show errors either on my console or my log file.

Folks, please any help with this?
Need to get this thing down ...

If you're using Tomcat, then the problem is that Tomcat is using the lava.util.logging standard API for logging, and it doesn't report all the details of the exception. The way I've always been successful in getting the details of the exception was to switch over to Log4J. Just search Google for "tomcat 6 log4j" and you'll find instructions. You'll want to set log4j.properties to be the following in order to get the details:

log4j.rootLogger=INFO, R
log4j.appender.R=org.apache.log4j.ConsoleAppender
log4j.appender.R.layout=org.apache.log4j.PatternLayout
log4j.appender.R.layout.ConversionPattern=%p %t %c - %m%n
log4j.logger.org.apache.catalina.core.StandardContext=DEBUG, R

Typically, this will reveal a NoClassDefFoundError exception or something like that. Whenever I get NoClassDefFoundError exceptions on hot deployment, my mind immediately jumps to the conclusion that I have a JAR conflict. Normally, there is a JAR in WEB-INF/lib that doesn't belong.

Hello,

I know that this is the old thread, but I hit the same error in 6.1 ICEFaces sample portlet. Sample portlet is working but my first ICEFaces portlet didn't work with the same error as Michaels one.

Difference is in liferay-plugin-package.xml in sample portlet. I needed to add these jar-dependencies into my portlet

portal-dependency-jars=\
    commons-beanutils.jar,\
    commons-collections.jar,\
    commons-digester.jar,\
    commons-fileupload.jar,\
    commons-lang.jar,\
    commons-validator.jar,\
    oro.jar

Maybe it helps someone...
