hello
i am using struts 1.2,Eclipse Platform Version: 3.4.2,mySql 5.0.1,jdk 1.5..
i have a login form(jsp) in which a user logs in,in case he doesnt enter his username and/or password an error is displayed using the <ul> tag and <html:errors> in the jsp. in the from class a vaidate method creates an actionerrors object adds all the errors to it and finally returns it.
the ids are linked in messageresource s.properties and appropriate message is diaplayed.
now i want to change the colour of the feild thats unfilled.. ie the username change its font to red in case it empty rather then a message.
thanks in advance.
code:
index.jsp
LoginForm.java
MessageResource s.properties
