<SORRY, I SENT THIS TOO EARLY>
I mostly have experience with original struts. But now I am attempting
to use Struts 2. I am trying to figure out how I can populate the
select tag.
I have created an action class, called Blast with the following
attributes:
1. List<Database> databases = new ArrayList();
There are two methods, getDatabases and setDatabases
I have created another class called Database with the following
attributes:
1. int id
2. String database
3. String databasetype
I want to use the select tag to access the List of Database objects in
the action class Blast.java
This is how I am using the action class:
<s:select name="database" list="databases" listKey="id"
listValue="database" "emptyOption="true"></s:select>
As you can see, I specify the list equal to databases which should
correspond to getDatabases in my action class, Blast. My listKey is
equal to id, which should correspond to the id field in my Database
class. And finally, listValue should correspond to database in my
Database class.
My jsp page fails to compile/execute giving errors like:
/view/Index.jsp(55,87) Unterminated <s:select tag
or
org.apache.jasper.JasperException: Unable to load class for JSP
I am including copies of the files in case someone is kind enough to
help a pathetic newbie out with this.
