I see that there is an `AnchorageDecember.json` environment file. I would like to load this and try running my scenario under those conditions. I see that there is an `HowTo-EnvironmentChange.cpp`, but it shows how to programmatically set environmental conditions, whereas I’d like to load the ones from the existing file. How can I do that? I tried this in Java:
```java
SEChangeEnvironmentalConditions env = new SEChangeEnvironmentalConditions();
env.setEnvironmentalConditionsFile("environments/AnchorageDecember.json");
this.pulseEngine.processAction(env);
```
But this is what gets printed in the log:
```auto

```
Seems like it didn’t work. What’s the right way to do this?

That should be correct…
I assume your working dir is the Pulse bin…
So, let me check that out…

If that is correct, I probably have the relative path incorrect. The working directory is in my application, where I have copied the environment directory. I’ll check the path.

Try adding a ./

No no, I see the same thing… hang on
Seems like Java is not doing something …

Yeah, the Java API is not coded right
I updated the API to work as you have understood it
I created a new branch off of the hemorrhage branch to address this
[https://gitlab.kitware.com/physiology/engine/-/tree/feature/environment\_java](https://gitlab.kitware.com/physiology/engine/-/tree/feature/environment_java)
I added a new HowTo and I believe this is doing what you would expect
I am going to have to go through the Java API and double check other actions that support files and make sure they are also correct…later…
But check this out, the skin temp is going down, so it looks like I successfully transported the patient into Alaska

Thanks for finding this!

Confirmed the branch is working for me, too – I didn’t even have to put the leading `./`. Thank you!
