Thanks for your help. But I don't think that is
causing the problem:
(a) for one thing, the other text written to
body content show up in the output. Only the
stuff inserted into the enclosing writer in
doAfterBody() is mysteriously missing.
(b) I am writing to the enclosing JspWriter -
not to the body content.
Consider the following:
<body>
<kobe:Filter>
I am a Laker Fan. I am Kobe.
</kobe:Filter>
<body>
What appears on output is:
I AM A LAKER FAN I AM KOBE
The periods are missing. What (I think) my doAfterBody()
is doing is to replace "." tokens with ".<br>" tokens.
Can you tell me where the <br> tokens that I inserted
vanished?
