Question

I have a JSF project working with JPA, I do this : retrive some data from mysql database then plot the data in a chart.

Locally works pretty fine, as you can see here:

So I deploy the project in my GlassFish 3 Open Source, which is running in a EC2 instance, then I try to make the same operation again but it seems the ManagedBean do not returns to the page correctly:

This is my ManageBean :

@ManagedBean(name="reportc")
@SessionScoped
public class ReportControl implements Serializable {
    private static final long serialVersionUID = 3269125738504434502L;

    @EJB LogEAO logEAO;

    private int quantity;

    @NotNull(message="informe um intervalo")
    private String time;

    @NotNull(message="informe um ponto")
    private String point;

    private Map<String, Object> data = new HashMap<String, Object>();

    @PostConstruct
    public void init(){
        quantity = 1;
    }

    public String getDataAsJson() {
        return new Gson().toJson(data);
    }

    public String generateReport(){
        this.setTitles();
        this.getValues(getLog());

        return "/showroom/report.xhtml?faces-redirect=true";
    }
    .. methods and get's and set's

I already look in into my server.log to see if there’s something wron but it seems everything is alright.

I really don’t know why this is happening, besides is my first time trying to deploy a project which use JPA and JSF together.
What could be doing this ?

EDIT:
Just one more thing, in local mode when I click to generate the report it takes some seconds to go to the database, make the maths and return to my page, but when it’s in production mode when I click to generate the report it just refresh the page, why is that happening ?
I really need to know why … help me out guys, please.

EDIT 2:

You guys can see it online here:

Answer 1

The solution was :

I had to give permissions to some user in MySQL, enable the remote connection in MySQL, put JDBC driver in glassfish_installation\glassfish\modules\ and restart it, initialize the logEAO and put the annotation @Table(name="table_name") because it depends of each file system in operationals system as can be seen here:

JPA: MySQL says table don't exist, but it exist actually.
