I looked at your first message and saw the code snippet you put there. I
tried out using your jsp code and put together a couple of classes & got it
working no problem:
<html:text property="data.rows[1].employeeName" size="30"
maxlength="30"/>
One problem I did have was I had to change the above from "EmployeeName" to
"employeeName" to get it working.
I also used the following classes:
In the Action Form:
private TestBean data = new TestBean();
public TestBean getData() {
return data;
}
I created a TestBean as follows:
public class TestBean {
private EmplBean[] rows = new EmplBean[] {new EmplBean("Fred"), new
EmplBean("John")};
public EmplBean getRows(int index) {
return rows[index];
}
}
I created an EmplBean as follows:
public class EmplBean {
public String EmployeeName;
public EmplBean(String name) {
EmployeeName = name;
}
public String getEmployeeName() {
return EmployeeName;
}
public void setEmployeeName(String name) {
EmployeeName = name;
}
}
