Re: [Q] Different handling tagfiles and normal tags classes

[Jan Luehe]

Torsten,

see JSP.8.3 ("Semantics of Tag Files"), 3rd bullet:

  For each invocation to the tag, the JSP Context Wrapper must present a
  clean page scope containing no initial elements. All scopes other than
  the page scope must be identical to those in the Invoking JSP Context
  and must be modified accordingly when updates are made to those scopes
  in the JSP Context Wrapper. Any modifications to the page scope,
  however, must not affect the Invoking JSP Context.
Hope this helps.

Tagfiles and tags get a jspcontext from the container at runtime. 
Tags get directly a normal pagecontext reference from the current jsp page. 
TagFiles instead get a wrapper around the pagecontext that wraps all 
set/get/findAttribute for the page scope to a local set of stored
attributes. 
When i declare an attribute in jsp with page scope, i never see it in a tag
file, but i see it in a 'normal' tag.

Interesting files: 
  org.apache.jasper.runtime.JspContextWrapper -> see
getAttribute(String)/getAttribute(String/int)
  org.apache.jasper.compiler.Generator -> search for setJspContext

Is there a reason why, i don't know? 

Best greeting 
 Torsten Fohrer
