deployment error:Failed to check xml, Server returned HTTP response code: 400 for dtd url in jBoss AS 7.1.1

[sarvya521]

I was deploying my war for my project. While deploying I encountered following error:

14:54:12,261 ERROR [org.jboss.as.server.deployment.scanner] (DeploymentScanner-threads - 1) JBAS015015: Failed checking whether D:\dev\jboss-as-7.1.1.Final\standalone\deployments\CSP\bin\WebContent\classes\com\anm\csp\dao\AccSettlementdef.hbm.xml was a complete XML: java.io.IOException: Server returned HTTP response code: 400 for URL: http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd

Please help me to resolve this issue.

Actually I am planning to migrate from JBoss 4.0.2 to jBoss AS 7 and want my same project to be deployed on it.

First error that I encountered is WEB-INF, then I changed it to WebContent.
but this error regarding xml validation, has not yet been solved.

I am testing this on jBoss AS 7.1.1 with Eclipse 3.7.2 (Indigo SR2).

I think that you have an error at AccSettlementdef.hbm.xml

You can try delete the row decalration DTD or SCHEMA

You have sure that you xml file is well-formed.
