Subject Repeater Form and collection
Date Thu, 25 Nov 2004 15:47:04 GMT
Hi all; i have this problem....... i can recover a Collection of objects from db; this collection
is made by objects of this kind:

import java.io.Serializable;

import it.eng.nikko.config.dao.exception.ConfigVOException;


public class ConfigVO implements Serializable {

    private String id;
    private String ipAddress;
    private String portNumber;
    private String webAppRoot;

    public ConfigVO(String newId, String newIpAddress, String newPortNumber,
                    String newWebAppRoot) throws ConfigVOException {

        if ((!(checkString(newId))) || (!(checkString(newIpAddress))) ||
            (!(checkString(newPortNumber))) || (!(checkString(newWebAppRoot)))) {

            throw new ConfigVOException("Exception in configuration parameter");
        }
        setId(newId);
        setIpAddress(newIpAddress);
        setPortNumber(newPortNumber);
        setWebAppRoot(newWebAppRoot);
    }

    public void setId(String value) {

        this.id = value;
    }

    public String getId() {

        return id;
    }

    public void setIpAddress(String value) {

        this.ipAddress = value;
    }

    public String getIpAddress() {

        return ipAddress;
    }

    public void setPortNumber(String value) {

        this.portNumber = value;
    }

    public String getPortNumber() {

        return portNumber;
    }

    public void setWebAppRoot(String value) {

        this.webAppRoot = value;
    }

    public String getWebAppRoot() {

        return webAppRoot;
    }

    private boolean checkString(String value) {

        return (value == null ? false : ((value.trim().equals("")) ? false : true));
    }

    public boolean equals(Object object) {

        if (this.getClass().equals(object.getClass())) {

            ConfigVO con = ((ConfigVO) (object));
            if ((checkString(con.getId(), this.getId())) &&
                (checkString(con.getIpAddress(), this.getIpAddress())) &&
                (checkString(con.getPortNumber(), this.getPortNumber())) &&
                (checkString(con.getWebAppRoot(), this.getWebAppRoot()))) {

                return true;
            }
            return false;
        }
        return false;
    }

    public String toString() {

        return "ConfigVO: " + this.id + " " + this.ipAddress + " " +
                this.portNumber + " " + this.webAppRoot;
    }

    private boolean checkString(String aString, String anotherString) {

        return aString.equals(anotherString);
    }
}

I must show a form formed by a table that has as row as Collection dimension; in order to
do this i think i must use <fd:repeater.... but i don't how to do it... can you help me?
I'll try to be clearer.... i have a Collection of ConfigVO object... i want to create a form
where there is a table in which every raw is a ConfigVO object rapresentation... how can i
do this?
