In Jboss5.1.0.ga, we are getting below error(full error stack trace is given in the end):

java.lang.NoSuchMethodException: No such accessible method: addFormBeanConfig() on object: org.apache.struts.config.impl.ModuleConfigImpl
at org.apache.commons.beanutils.MethodUtils.invokeMethod(MethodUtils.java:250)

while deploying our_application.war file.

If we delete struts.jar file from /WEB-INF/lib the error is removed. But we dont want to delete this jar, since we need it while compiling and creating .war file.

If we do not delete the struts.jar and do the below changes:

Set "useJBossWebLoader" property to 'true' as <property name="useJBossWebLoader">true</property> in default\deployers\jbossweb.deployer\META-INF\war-deployers-jboss-beans.xml file.

it still gives the same error.

However we fixed this error in Jboss4.2.2, without deleting struts.jar, by changing as below:
<property name="useJBossWebLoader">true</property>
in /default/deploy/jboss-web.deployer/META-INF/jboss-service.xml file.

Any suggestion to fix the error without deleting struts.jar, in Jboss5.1 will be highly apreciated.
