JSP 1.1 presents a method for extending the JSP flag, which is named "Logo library." These libraries allow other flags similar to those of Jsp:include or jsp:forward, but they are not JSP: prefix and also have some attributes attached to the attachment.
To introduce the logo library, we use the Blazix tag library as an example in this tutorial. This logo library can only be used in Blazix servers, which you can download for free.
Each logo library has its own logo library special document. In order to use the logo library, you can use the "taglib" directive to indicate where the logo library "description" is located. For the Blazix logo library, the directive is as follows:
<%@ taglib prefix= "BLX" uri= "/blx.tld"%>
The "uri" in the above sentence indicates where the logo library description is located. The prefix for the tag library is different. This instruction means that we can use the BLX: to use the flags in the library. The Blazix logo Library provides a blx:getproperty flag. This flag allows the user to edit the form data. Now, in the getname.jsp file, we add a jsp:usebean and place the form in Blx:getproperty:
<%@ taglib prefix= "BLX" uri= "/blx.tld"%>
<jsp:usebean id= "user" class= "UserData" scope= "Session"/>
<HTML>
<BODY>
<blx:getproperty name= "User" property= "*" >
<form method=post action= "savename.jsp" >
What ' s your name? <input Type=text Name=username size=20><br>
What ' s your e-mail address? <input Type=text Name=email size=20><br>
What ' s your age? <input Type=text name=age size=4>
<p><input type=submit>
</FORM>
</blx:getProperty>
</BODY>
</HTML>
From the above code we can find that Blx:getproperty does not end with/>, but ends with </blx:getProperty>. This statement enters all form input areas into the blx:getproperty so that they can be modified correctly by the tag library.
Then create a connection from getname.jsp to nextpage.jsp, and you'll find the bean's data automatically displayed in the input area. So now the user can edit the data.
