Apache ignite gives error when you refresh webpage

I'm new to apache ignite.

  1. I have a java web project which gets results that are cached by apache ignite.
  2. I have a separate project that starts and caches results from the database and starts a server node

When I load my web page the first time, all is good and it picks up my results. But if I refresh my page again it gives me an error saying:

Default Ignite instance has already been started.

my code:

public MyConstructor() {
    Ignition.setClientMode(true);
    ignite = Ignition.start();
}

So what happens is when I refresh my page it loads the constructor everytime. Is there a better way to find if a node exists and use that? Or if there is a better way to achieve this.

Solution

  • Use Ignition.TryGetIgnite() ?? Ignition.Start() construct to either get an existing instance or start a new one.
