Indexed Property Example Code

Question

Is there an example out there for a Java Newby - I am trying to save data in an array - that is using the indexed property in a SessionBean.
I have then added the indexed property and bound the value to it:
* Indexed getter for property rule.
* @param index Index of the property.
* @return Value of the property at <CODE>index</CODE>.
public Long getRule(int index) {
return this.rule[index];
* Indexed setter for property rule.
* @param index Index of the property.
* @param rule New value of the property at <CODE>index</CODE>.
public void setRule(int index, Long rule) {
this.rule[index] = rule;
public String button1_action() {
setValue("#{AdminBean.rule[1]}", selector.getValue());
I am getting the followong error:
Exception Details: org.apache.jasper.JasperException
Error getting property 'rule' from bean of type magicwheel.AdminBean
Possible Source of Error:
Class Name: org.apache.jasper.servlet.JspServletWrapper
File Name: JspServletWrapper.java
Method Name: service
Line Number: 384
Source not available. Information regarding the location of the exception can be identified using the exception stack trace below.
Can anyone help, possibly with some example code?
Thanks,

Answer 1

public String button1_action() {
setValue("#{AdminBean.rule[1]}",
selector.getValue());
How about
getAdminBean().setRule(1, selector.getValue());Assuming that selector.getValue() returns a Long and that AdminBean is either an Application, Session, or Request Bean.
Best regards
