RE: null pointer error
This turned out to be a IBM WTE bug. The trick is all web apps must use JSP 1.1 Thanks to Amit for the answer. - Here is what Amit said -- Yes I did find a workaround the problem. The believe this is a bug is in the servlet engine. You need to change the webapp config file for ALL the webapps in your system to use jsp 1.1 compiler. Just changing the default_app.webapp to jsp 1.1 is not enough.VAJ seems to get confused if it encounters any webapp config file which does not specify jsp 1.1 compiler. Its either all or nothing. Please refer to the following email exchange I had with another person who inquired about the same problem. Hope it helps. Good luck, Amit --- Thank you! It works now! That's a bad bug. I was working in a customwebapp, but I guess you need to change all of the webapps to 1.1.

I'm having problem with using tag libraries with a body under VAJ3.5.3 and WTE. The tag library does not work when there is body. Itthrows a NullPointerException from the jsp generated servlet code. The specific line of code where the problem occurs isout = pageContext.pushBody();The JspWriter, out is returned as null. Subsequent call to out.printfails with a null pointer exception. Has anybody encountered thisproblem? Keep in mind that the problem only occurs using taglibraries with a body (i.e. your tag class extends BodyTagSupport).
RE: null pointer error
I dont
think html:text was designed to take a body - in the tld file for the
html:hidden tag the body parameter is set to empty and they both extend
the same parent class (BaseFieldTag).
BaseFieldTag is a child of BaseHandlerTag which extends
BodyTagSupport and BaseFieldTag returns EVAL_BODY_TAG from its
doStartTag() method - but I think this looks like a mistake because its not been
written to process the body - I think it should really return
SKIP_BODY.
My
advice - dont put anything in the body.

Re: null pointer error
I think you have to have the html:text tag inside an
html:html tag. For example:
html:html
html:text property = "username" size =
"20" maxlength = "20" value = "test"
/html:text
/html:html
I think that might be the source of your problem.

_jspx_th_html_text_1.release();
}
The proplem is pageContext.pushBody() returns null which then fails the
next time something is written to out.
Any ideas.

RE: null pointer error
Yes closing tags are there also.
I even tried
html:text property=username size=20 maxlength=20 value=test/
and
html:text property=username size=20 maxlength=20 value=test
test/html:txt
To see if having a body would matter, no difference.
I think it is a problem with IBM.
out = pageContext.pushBody();
returns a null.
put the JSP code is to convoluted for me to see why.
I am download WebLogic 6.0 and I will try it there.

Silly question, perhaps, but you do have /html:text and not /html:txt,
don't you?

Is your text element contained within an html:form
