Hi all
I have created a jsp tag that will look up a collection (of
LabelValueBeans) and return the label of the value. For example we store
position description in a code table such as
Code Description
1Director
2Manager
3Assistant Manager
4Staff
In the User table, we store
Logon Position
Jack 1
Jill 2
Charlie 2
In a UserList.jsp
logic:iterate ...
Logon : bean:write name=user property=logon/
Position: bean:write name=user property=position/
/logic:iterate
This will produce the following list
Logon : Jack Position: 1
Logon : Jill Position: 2
Logon : Charlie Position: 2
To display the position description instead of the position number, I
added a list of LabelValueBeans to the session (ie
session.setAttribute(session.positionlevel); ) and changed the JSP to
the following.
logic:iterate ...
Logon : bean:write name=user property=logon/
Position: ma:droplist name=user property=position
labelValueList=session.positionlevel/
/logic:iterate
The droplist tag will produce the following with
Logon : Jack Position: Director
Logon : Jill Position: Manager
Logon : Charlie Position: Manager
I am happy to contribute this back the STRUTS tag lib or if anyone is
interested, let me know and I will send you the code. This functionality
consists of
ma-droplist.tld
com.ma.struts.taglib.droplisttag.java
com.ma.struts.taglib.droplisttag.class
To add the functionality to your JSP you will need to
1) Add the tld to your web.xml.
2) Add the tld to your JSP.
This tag also works with indexed beans as droplisttag.java is extended
from writetag.java.
