It's certainly possible to generate Javascript code using tag extensions; in my most recent project, we have that for precisely this purpose -- sending focus to an input field in error situations.

One approach might be to use a runtime expression as the value of the "focus" attribute. Then, your action could set some appropriate request attribute to the name of the field to be focused on, and your expression could pick up the value. At least with the most recent nightly 1.0 builds, all of the custom tags take runtime expressions for all attributes. -- Ted Husted, Husted dot Com, Fairport NY USA. -- Custom Software ~ Technical Services. -- Tel 716 425-0252; Fax 716 223-2506. -- http://www.husted.com/ Craig
RE: sending user to a anchor on a page.
Perhaps an interstitial jsp like this?
%
String url = request.getParameter("url");
String anchor = request.getParameter("anchor");
String whereTo = url + "#" + anchor;
response.sendRedirect(whereTo);
%
referenced in action.xml as:
...
inputForm="interstitial.jsp?url=page.jspanchor=anchorName"
...
If your servlet engine throws an exception on the redirect, you could
alternately write in a meta refresh tag, with the downside that the
interstitial would show up in the browser.

Subject: sending user to a anchor on a page.
I was wondering if there was any way to send a user to a specific
portion of
a page after the action class has executed.
as an example lets say that I have a user registration page. If the
user
inputs some bugus information I would like to return
them to that exact area of the page that they need to correct the
info.
So there is the page
userReg.jsp
The Form class
UserRegForm.java
the Action class
UserRegAction.java
what I was thinking for the action.xml doc is something like
action path="/RegisterUser"
actionClass="com.userapp.UserRegAction"
formAttribute="UserRegForm"
formClass="com.userapp.UserRegForm"
inputForm="/RegisterUser/userReg.jsp"
forward name="success" path="/App/ShowInfo.action"/
forward name="failure"
path="/RegisterUser/userReg.jsp"/
forward name="badzip"
path="/RegisterUser/userReg.jsp#zip"/
/action
where zip is the name of an anchor on userReg.jsp
This does not work though
all I get is a 404 error and nothing in the webservers output or log
files.
Any help or suggestions would greatfully appreciated.
Thank you,
Rex Oleson
