[JBoss-dev] New tomcat jsp error reporting behavior

[Scott M Stark]

Just ran into a new behavior in the tomcat 5.5.16 regarding jsp errors that is pretty nice. Either a compile or exception shows a line number delimited fragment of the jsp page that caused the problem. For example:

 

org.apache.jasper.JasperException: Exception in JSP: /jmx-test.jsp:31

 

28:       String[] sig = {"java.lang.String", "java.security.Principal", "java.lang.Object"};
29:       Set roles = (Set) conn.invoke(secMgr, "getUserRoles", params, sig);
30:       if( roles == null || roles.size() == 0 )
31:          throw new SecurityException("No roles found for jduke/theduke/jmx-console");
32:       out.print("Roles: "+roles);
33:       out.print('\n');
34:    }

 

Stacktrace:
org.apache.jasper.servlet.JspServletWrapper.handleJspException(JspServletWrapper.java:504)
org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:375)
org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:314)
org.apache.jasper.servlet.JspServlet.service(JspServlet.java:264)
javax.servlet.http.HttpServlet.service(HttpServlet.java:810)
org.jboss.web.tomcat.filters.ReplyHeaderFilter.doFilter(ReplyHeaderFilter.java:96)
