    springframework unknownHostException

    Jamie Newbie

      Hello,

      if anyone can point me in the right direction with this, I'd be very grateful.

      I'm trying to deploy my application offline, but keep hitting an java.net.UnknownHostException exception because jboss can't resolve the spring dtd (http://www.springframework.org/dtd/spring-beans.dtd). I've added it to the entity map on the JBossEntityResolverMgr service, but doesn't seem to make a difference, even when I put a jar containing the spring-bean.dtd in the jre lib/ext dir.

      It's not an issue with an internet connection.

      I'm using jboss-4.0.3SP1 with jdk1.5 and xerces 2.8

      cheers


      -Jamie

        • 1. Re: springframework unknownHostException
          Jamie Newbie

          found the solution to this by adding the spring dtd entry to the xmlresolver-service.xml file in jboss_home/server/deploy

          as such:
          .....

          -//SPRING//DTD\ BEAN//EN=org/springframework/beans/factory/xml/spring-beans.dtd

          ....

          Also ran into similar issues with tiles in struts 1.2 offline (not finding dtd), even when adding the dtd to the xmlresolver, but after upgrading to struts 1.3.5, the problem went away, and the app loads fine offline.

          cheers
