You have colon after the `except` keyword **and** at the end of the line. The first one doesn't belong. ~~(And why is this in this topic?)~~ _Moved to a new topic._

```auto
from java.lang import Exception as JavaError
logger = system.util.getLogger("yourLoggerName")

try:
    test = 1/0
except JavaError, je:
    logger.warn("An error occurred", e)
except Exception, e:
    logger.warnf("An error occurred: %s", e)

```

I now recommend that you use Throwable instead, all Java Exceptions are derived from the Throwable interface so it is more verbose in what it catches.

```auto
from java.lang import Throwable
logger = system.util.getLogger("yourLoggerName")

try:
   test = 1/0
except Throwable, t:
    logger.warn("An error occurred", t)
except Exception, e:
    logger.warn("An error occurred", e)

```

In the snippet you've provided I do not see where you have included the import. You must import the Java Type to use it.

You cannot put jython exceptions into loggers. Use `PythonAsJavaException()` to wrap them.

`PythonAsJavaException` can be found in my [later.py](https://www.automation-pros.com/ignition/later.py) script.
