Maven project: jsf12-login.zip
Note: If you test it with other browsers, please post a comment to let me know what it works on. The list below is what I have available to me.
Compatibility
- Mozilla Firefox 4
- Internet Explorer 8
- Chrome 11
- Safari 5
- Opera 11
Note: The xhtml form below did not work on Internet Explorer 8 until I disabled the comments in the
web.xml file. There is a comment in the file which also indicates that it is an issue with IE 8.Note: The
login.xhtml form uses an HTML based form and not a JSF <h:form /> tag. login.xhtml
