Well, I have a struts development using the tomcat server. I have a JSP, logon.jsp and I could not exactly understand in general what these lines are doing... <html:form action="/logon" focus="username" onsubmit="return validateLogonForm(this);"> <table border="0" width="100%"> <tr> <th align="right"> <bean:message key="prompt.username"/>: </th> <td align="left"> <html:text property="username" size="16" maxlength="18"/> </td> </tr> especially something like this <bean:message key="prompt.username"/>: Thanks.
