Subject: how to create a list style bean?
Hi there,
I'd like to create an application scope bean for easy table row coloring
(tomcat 5.5.9, struts 1.2.7, using struts EL).
<jsp:useBean id="rows" scope="application" class="RowBean"/>
...
<logic:iterate id="book" name="booklist" indexId="i">
<tr class="${rows[i]}">
...
Where the RowBean is meant as a virtual list returning the proper css
class
for each row index. But my subclassing does not work:
public class RowBean extends java.util.Vector<String> {
public String get( int idx ) {
return idx % 2 == 0 ? "even" : "odd";
}
}
I get the following error:
javax.servlet.jsp.el.ELException: Unable to find a value for "0" in object
of
class "RowBean" using operator "[]"
org.apache.commons.el.Logger.logError(Logger.java:481)
org.apache.commons.el.Logger.logError(Logger.java:498)
org.apache.commons.el.Logger.logError(Logger.java:611)
org.apache.commons.el.ArraySuffix.evaluate(ArraySuffix.java:340)
...
This would mean that my rowbean is not "instanceof List"?!
What am I doing wrong? Is there a different, more elegant way for this
task?
(I cannot use JSF).
Regards,
Holger Klawitter
