Debugging struts exceptions - correction

[Will Spies/Towers Perrin <sp...@towers.com>]

Oops...I put the wrong tag in there:

<html:form action="/logon" focus="badproperyname">

(see what I mean?)

Seems certain exceptions don't come with very good explanations. For
example, I have a tag which had a bad property:

<html:text property="badpropertyname" size="16" maxlength="16"/>

If 'badpropertyname' does not exist the exception I see in the log file is:

javax.servlet.ServletException: runtime failure in custom tag 'form'
     at jsp_servlet._logon._jspService(_logon.java, Compiled Code)
     at weblogic.servlet.jsp.JspBase.service(JspBase.java:27)
     at
weblogic.servlet.internal.ServletStubImpl.invokeServlet(ServletStubImpl.java:106)
     at

     at

weblogic.socket.MuxableSocketHTTP.execute(MuxableSocketHTTP.java:252)
     at weblogic.kernel.ExecuteThread.run(ExecuteThread.java, Compiled
Code)


This doesn't always happen but it happens here and this is probably a
pretty common error. Any suggestions?

P.S. I use WLS 5.1 SP8
