My application developed with struts, now I try to deploy under JBoss

but I see following errors

> 
> 12:40:41,939 WARN [org.jboss.as.ee] (MSC service thread 1-5) JBAS011006: Not installing optional component org.apache.struts.taglib.template.PutTag due to exception: java.lang.ClassNotFoundException: org.apache.struts.taglib.template.PutTag from [Module "deployment.backend.ear.frontend-war.war:main" from Service Module Loader]
>  at org.jboss.modules.ModuleClassLoader.findClass(ModuleClassLoader.java:190) [jboss-modules.jar:1.1.1.GA]
> 
> 
> 

and similar exceptions, seems it does not understand struts and his tags, but all libraries in the web-inf/lib folder. this is fully working application.

Struts version 1.3.8 > I am migrating project from JBoss 5 to JBoss 7.

have anyone similar problems?

Thanks
