Hello Kay,

thank you for the answer.

With this jar (commons-math) I tested and it works.

But with my jar didn't work, and I couldn't find any log to identify the

problem . Any idea of how to debug this?

The jar i'm trying to import is this

https://bintray.com/jai-imageio/maven/download_file?file_path=com%2Fgithub%2Fjai-imageio%2Fjai-imageio-core%2F1.3.1%2Fjai-imageio-core-1.3.1.jar

Anyway, pcaspy could be a good solution too.

Regards

Hi:

Fundamentally, what Charles-Henri suggested is correct.
For example, if you want to use the commons-math jar, you can do this:

import sys
sys.path.append(‘/full/path/to/your/copy/of/commons-math3-3.2.jar’)
from org.apache.commons.math3.fitting import CurveFitter

If your import fails, check the log file to see if there are error messages.
For example, maybe some class in the jar cannot be resolved because of further dependencies.

Note, however, that BOY will execute jython scripts on the UI thread, so all of CSS will freeze while you’re executing your script.
If you really need to do something that takes longer, you should create a Runnable inside your script and execute that on a new Thread.
Then use Display.asyncExec() for interacting with the widgets back on the UI thread.

Ideally, move what you think you have to do in a script into an IOC (which may be a pcaspy-based python IOC) and in the UI you then just read/write PVs. All the logic is in the IOC.

Hi Pattard,

thank you for the answer.
I tried your solution, but didn't work.

The console error is this:
"ImportError: No module named github"

I'm trying to import a module called com.github.imageio, but the
cs-studio didn't find it....

I'm tried another jars that didn't work too.  I'm tried to add path inside my code too, but nothing works.

What version of CSS you are using?

Regards

Hi Gabr iel,

Can you show the console error ? I’ve got this kind of problem with
Jython imports. Even if you modify PYTHONPATH or CS-Studio PYTHONPATH
preferences it doesn’t work. To solve it I needed to create a python
script named ImportDependencies.py :

“

#Python imports

import sys

from os.path import expanduser

# Get Home path

HOME_PATH = expanduser("~")

print 'importDependencies HOME_PATH '+str(HOME_PATH)

# Add librairies

sys.path.append(str(HOME_PATH)+'/path/to/jar/file')”

In a second time, you have to import ImprtDependencies.py in your
Jython/Python script like this : “import ImportDependencies”.

Best regards.
