the file jsp doesn’t compile
In MyEclipse or in Tomcat?
C:\eclipse\jakarta-tomcat-5.0.28\work\Catalina\localhost\TesteStruts\org\apache\jsp\MyJsp_jsp.java:109: _jspx_meth_html_base_0(javax.servlet.jsp.tagext.JspTag,javax.servlet.jsp.PageContext) in org.apache.jsp.MyJsp_jsp cannot be applied to (org.apache.struts.taglib.html.HtmlTag,javax.servlet.jsp.PageContext)
if (_jspx_meth_html_base_0(_jspx_th_html_html_0, _jspx_page_context))
It looks like your J2EE libraries are being mismatched. You are most likely developing against J2EE 1.3 libraries, and once you deploy the project to Tomcat the J2EE 1.4 libraries that Tomcat uses are being used to compile the page and failing.
OR, you have accidentally included the J2EE library files in your project itself, so they are getting deployed to your WEB-INF/lib directory (and they shouldn’t be).
