Hi everyone,  
I have 2 questions  
**First one:**  
I need to get all Sessions IDs to send msg to them using the message handler, there are any way to do that?  
**Second one:**  
if i try to get The current SessionId to pass the message directly with this code:

> String SessionId = InternalSession.SESSION.get().getSession().getSessionId().toString();

I got this error:

```auto
java.lang.NullPointerException: null

```

I think I had misunderstood using **InternalSession** , should I import its package and use it directly or declare it in specific Scope  
Thanks in advanced

And you are trying to do this in a model (more specific the gateway delegate)?

Or just trying to get it through a (system) function so you can use it in an external lib?

I made a (system) function for that once like this.

You'll also need to register these functions in the gateway and designer

You can probably get all the sessionInfo's from here  
[com/inductiveautomation/ignition/common/script/builtin/SystemUtilities.html#getSessionInfo()](https://files.inductiveautomation.com/sdk/javadoc/ignition81/8.1.15/com/inductiveautomation/ignition/common/script/builtin/SystemUtilities.html#getSessionInfo())

You capture it in your module's setup hook and save it in a field. I tend to use a private static field and matching getter so the rest of the module can obtain it via that static method.
