AW: java.lang.NullPointerException......Plz Help Me

2001-05-17 Thread Ralph Einfeldt 

Have a look at line 123 in the generated source file
_0002fjsp_0002fNew_0002fdyeing_0002ejspdyeing_jsp_0.java
to see which statement causes the exception.

If you found the region and can't see the error, try to
reduce the page to the bare minimum that reproduces the
error and post the source for that.

I have seen a similar problem which I posted to tomcat dev.  The
generated source code is

...
} finally {
if (out != null) out.flush();
if (_jspxFactory != null) 
_jspxFactory.releasePageContext(pageContext);
}
...

and the error came from the releasePageContext method which tried to do
something with pageContext.  It seems quite repeatable if tomcat is run
with security.  e.g. standard 3.2 examples/numguess.  My case is when I
have access controls turned on and am doing authentication.  No answer
in the dev list.  This always occurs if you have no permissions when
compiling the login page which is the result of a redirection from the
protected resource.  This is in 3.2.2b4

Seems to be a general problem when run with security.

on line 123 in
_0002fjsp_0002fNew_0002fdyeing_0002ejspdyeing_jsp_0.jav
there is the following code:

} catch (Exception ex) {
if (out.getBufferSize() != 0)
out.clearBuffer();
pageContext.handlePageException(ex);
} finally {
out.flush();
  
_jspxFactory.releasePageContextpageContext);
}
