Hello

We have updated out gateway to 38, and I have seen that the SAP JCO library files had been removed. Folders are intact but files have been removed.

Is there any way to avoid this? We tend to update our gateway frecuently.

Thanks!

The best way might be to keep it somewhere outside Ignition and then add an entry to ignition.conf to put that folder on the class path:

```python
# Java Classpath (include wrapper.jar) Add class path elements as
# needed starting from 1
wrapper.java.classpath.1=lib/wrapper.jar
wrapper.java.classpath.2=lib/core/common/*
wrapper.java.classpath.3=lib/core/gateway/*

wrapper.java.classpath.4=C:/path/to/my/sapjco3/*

```
