# Integrate With Non-Java Code

### LotusScript (HCL Notes/Domino)

LotusScript to Java (LS2J) allows you to call Java code directly from your HCL Notes/Domino application code.

#### Step 1: Download SOFA

* [Download *SOFA*](/quick-start/downloads.md) and rename the file *SOFA.jar* to *SOFA.zip*

#### Step 2: Import the SOFA classes into HCL Domino Designer:

* Expand *Code > Script Libraries*
* *New Script Library*: Create a new library (e.g. "OAuth-SOFA-Java") of Type *Java*
* *Import > Archive* and select the directory with the *SOFA.zip* file from the previous step
* *Save* the script library 

{% hint style="info" %}
These Java class files will be stored in the background. There will be no visible information in HCL Domino Designer.
{% endhint %}

#### Step 3: Use the code

Add the following two statements in your LotusScript code:

{% code lineNumbers="true" %}

```visual-basic
'-- LotusScript to Java Connector
UseLSX "*javacon"

'-- SOFA Java Classes
Use "OAuth-SOFA-Java"        '-- Script library from step 2
```

{% endcode %}
