This page provides techniques to center things with CSS: Some examples: P { text-align: center } H2 { text-align: c... When you specify " margin-left: auto " and " margin-right: auto ", the thing that gets centered is actually the block . So you have to limit the width of the block to see the centering effects (" width: 6em " for P.blocktext above). For Internet Explorer (IE), this works only when you have the doctype header in the HTML: <!doctype html public '-//W3C//DTD HTML 4.01//EN' ... Otherwise, IE is in quirks mode and wouldn't recognize the CSS directives.

However, the values for one and two must be passed in from pageScope , requestScope , sessionScope , etc. Values defined by struts bean:define are not interpreted. Important: JSTL tags work with servlet spec 2.4 only. So your web.xml must start with this: <?xml version = '1.0' encoding = 'windows-1252'?> ... Not this: <?xml version = '1.0' encoding = 'windows-1252'?> ... However, the latter does work with struts-el tags.

iretuotiowur, The reason I used block to render the labels is to avoid long labels from flowing underneath the checkbox. I'm not sure I understand your proposed solution. As far as I know, text-indent only applies to the first line of a paragraph. And I just found that Firefox does not honor it for label s (IE indents the first line as usual). For example, this page: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Stric... renders like this in Firefox:

This note records my struggle to get a checkbox aligned with its label in Firefox and IE. Starting HTML code. Use default attributes. Both checkbox and label float to the left. <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Stric... IE looked OK. Firefox is messed up. Long label shifted to the next line. IE 7: Firefox 3.0.6: Set width of label to that of the containing DIV: <style type="text/css"> label { display:... Both IE and Firefox shift the label to the next line. That's reasonable because the DIV isn't wide enough to contain the label and the browser tried its best to render the label properly. IE 7 and Firefox 3.0.6: Set width of label to be less than the containing DIV: <style type="text/css"> label { display:......

Follow these steps to prevent form double submission in struts: In the action class leading to the display of the form, call saveToken(request) In the action class handling the form submission, check the validity of the token by calling isTokenValid(request) . If token is valid, reset the token by calling resetToken(request) , then continue processing the form submission. Otherwise, skip form processing since it's double submission. How doe it work? saveToken generates a unique token and saves it in the session under the key org.apache.struts.action.TOKEN . When the form is rendered, the struts html:form tag generates a hidden field named org.apache.struts.action.TOKEN . Upon form submission, isTokenValid compares the token stored in the session with that submitted from the form. If they are equal, return true....
