Spring one to many association not working - nested loop throws exception

[Maciej Kowalski]

Hi guys!

In my project I use Spring 3.0.0.RELEASE and Hibernate 3.6.10. I also use JDK7 and PostgreSQL 9.1.9.

Heres goes the dependencies from pom.xml file

I have following DB schema:

CREATE TABLE applications (
    id serial PRIMARY KEY,
    name character varying(255),
    ip character varying(255),
    port integer,
    alive boolean
);

CREATE TABLE application_states (
    id serial PRIMARY KEY,
    cpu_percentage_use integer,
    disk_write_kb integer,
    disk_read_kb integer,
    alive boolean,
    thread_count integer,
    memory_percentage_use integer,
    created_at timestamp without time zone NOT NULL,
    name character varying(255),
    application_id integer REFERENCES applications(id)
);

When I want to use nested forEach loop in JSP view I get exception.

JSP:

    <c:forEach items="${applications}" var="application">
    {
        "id":${application.id},
        "name":"${application.name}",
            "ip":"${application.ip}",
            "port":${application.port},
        "alive":${application.alive}
        "other":{
        <c:forEach var="applicationState" items="${application.applicationStates}">
        "id":"${applicationState.id}"
        </c:forEach>
    }
    },
    </c:forEach>

Now I will paste code from my project, so anyone can help me with debug:

[Himanshu bisht bebo]

can you please provide me spring-servlet.xml

[Maciej Kowalski]

I deleted this project.

Well I had a deadline - 15 June.

I posted this question on this board and spring - got no help.

So I rewrote whole project in 1 day in Ruby on Rails + implemented new functionality.

JEE is so frustating compared to Rails.
