java.lang.NoClassDefFoundError: com/ctc/wstx/io/CharsetNames during deployment

[apatispelikan]

Hello,

previously I updated a deployed ear via webadmin-console ("Manage Deployments"). I had to remove an old version of my application in "Server Group Deployments" and add the new version (previously uploaded using "Add Content") to my server-group "Add to groups" (by the way: this is a cluster of two nodes and I use domain-mode). I've done this several times before but this time deploying the new version failed:

16:09:17,271 INFO  [org.jboss.as.server] (host-controller-connection-threads - 6) JBAS015870: Deploy of deployment "diginews-v1.8.3b.ear" was rolled back with failure message {"JBAS014671: Failed services" => {"jboss.deployment.subunit.\"diginews-v1.8.3b.ear\".\"diginews.jar\".INSTALL" => "org.jboss.msc.service.StartException in service jboss.deployment.subunit.\"diginews-v1.8.3b.ear\".\"diginews.jar\".INSTALL: JBAS018733: Failed to process phase INSTALL of subdeployment \"diginews.jar\" of deployment \"diginews-v1.8.3b.ear\" Caused by: java.lang.NoClassDefFoundError: com/ctc/wstx/io/CharsetNames"},"JBAS014771: Services with missing/unavailable dependencies" => [.....

Reactivating the old version didn't work either. I had to stop and start all servers of this group. Then my ear deployed without an error.

No I'm wondering:

• I'm not using the missing class within my project
• As you can see by the version of the ear-file (1.8.3b), this was not the first upgrade I did and all others worked perfectly
• Restarting the servers helped, so the ear seems to be fine

What might this be - or in other words: How can I avoid this? I was lucky that restarting the servers did fix it, but if not I would have an interuption of the service much longer then some seconds I expect for a redeployment. Unfortunately (but otherwise not) this is not reproducable!? Any suggestions?

Thanks,

Stephan

Hi,

    The missing class "com/ctc/wstx/io/CharsetNames" is present inside the "$JBOSS_HOME/modules/org/codehaus/woodstox/main/woodstox-core-as*.jar" file.

     So try adding the dependency to this module inside your application in order to make this Jar/classes available:

<?xml version="1.0" encoding="UTF-8"?>

<jboss-deployment-structure>

   <sub-deployment name="YOUR_WAR.war">

     <dependencies>

       <module name="org.codehaus.woodstox" />

     </dependencies>

   </sub-deployment>

</jboss-deployment-structure>

Thank you for your suggestion. I have several module-dependencies but my problem is that I do not need this class within my code and all previous tries to deploy my ear succeeded. For one time I got this error and after the server-restart it was gone. Maybe there is an indirect dependency I don't know!? I will add this module-dependency but I think that anything didn't work during undeploying my old-version-ear and it was not removed cleanly - but this is only a guess.

EAP 6.4 - the same problem:: NoClassDefFoundError: com/ctc/wstx/io/DefaultInputResolver

What works is to restart Jboss / whole cluster. So far we didn't manage to find out any other working solution.
