[jboss-user] [Tomcat Integration] - javax.servlet.ServletException: java.lang.AbstractMethodErro

hi, In my jboss (jboss 4.2.3 GA) when i takes my application page i am getting getiitng an http 500 error page. This is not for all pages. The pages which is called in an iframe is having the issue. | javax.servlet.ServletException: java.lang.AbstractMethodError: javax.servlet.jsp.JspFactory.getJspAp | plicationContext(Ljavax/servlet/ServletContext;)Ljavax/servlet/jsp/JspApplicationContext; | org.apache.jasper.servlet.JspServlet.service(JspServlet.java:273) | javax.servlet.http.HttpServlet.service(HttpServlet.java:803) | org.jboss.web.tomcat.filters.ReplyHeaderFilter.doFilter(ReplyHeaderFilter.java:96) | | root cause | | java.lang.AbstractMethodError: javax.servlet.jsp.JspFactory.getJspApplicationContext(Ljavax/servlet/ | ServletContext;)Ljavax/servlet/jsp/JspApplicationContext; | org.apache.jsp.ServerInfo_jsp._jspInit(ServerInfo_jsp.java:63) | org.apache.jasper.runtime.HttpJspBase.init(HttpJspBase.java:52) | org.apache.jasper.servlet.JspServletWrapper.getServlet(JspServletWrapper.java:158) | org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:328) | org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:336) | org.apache.jasper.servlet.JspServlet.service(JspServlet.java:265) | javax.servlet.http.HttpServlet.service(HttpServlet.java:803) | org.jboss.web.tomcat.filters.ReplyHeaderFilter.doFilter(ReplyHeaderFilter.java:9 | Actually one mistake i pointed out is my ear contains a 3rd party jar and i removed it and put the same in default/lib directory. But still that iframe jsp's are making issues. Is it becasue it using jsp and servlet diff spec and tomcat 6. Everything is perfectly working when i uses 3.2.5 application.
