Struts tag problem when migrating to 7.0 from 5.1

Question

          We currently have an application using struts running on WLS 5.1. When we use the
          application
          on WLS 7.0 and WLE 7.0 we get errors for the tag properties that are not defined
          in the tag
          library. In 5.1 WLS seemed to just ignore them and rewrite them but in 7.0 it
          seems to validate them so we can't actually include regular HTML tags.
          The JSP is:
          ', 'Terms', 600, 800 );">
          <html:img page="/jsp/images/viewbill.gif" width="78" height="19"
          border="0" target="_blank"/>
          </a>
          and the error message we are getting is:
          Parsing of JSP File '/jsp/pages/ViewMyBill.jsp' failed:
          /jsp/pages/ViewMyBill.jsp(40): for tag 'img' handler type 'org.apache.struts.taglib.html.ImgTag'
          has no property 'target'
          probably occurred due to an error in /jsp/pages/ViewMyBill.jsp line 40:
          </a>

          tag 'img' handler type 'org.apache.struts.taglib.html.ImgTag' has no property

          weblogic.servlet.jsp.JspLexer.nextToken(JspLexer.java:1892) at
          <snip>
          In 5.1 this would result in the following HTML tag:
          <a href="javascript:openBareScrollableWindow( '/selfcare/GoViewMyBill.do',
          'Terms', 600, 800 );">
          <img src="/selfcare/jsp/images/viewbill.gif" height="19"
          width="78" border="0">
          </a>
          The struts.jar is located correctly in the WEB-INF/lib folder as are the tag libraries
          - it's the
          same folder structure for 5.1 and 7.0.
          Any ideas on what's wrong here appreciated.
          Thanks in advance,
