Hi Prof,

appears the forum is not accepting jar files from the bottom checkbox "Upload new EJS jar file."

for your info ;D

Let me try to upload ejs jar file!

The file was not uploaded when I first tried it. However, I was able to upload it the second time.  
I am aware of this problem: the file was not upload successful every time. But I was not able to find out the bug (The problem did not happen every time, so it is difficult for me to fix it).

Please try to upload your file again if the simulation was not show up.
And you have to save your file under users/ sub-directory, otherwise, it would not work, either.

thanks!

done
i uploaded using E:\workspace\source\users\sgeducation\lookang and it worked!

i think because it was a brand new simulation it was at the default E:\workspace\source\

I need to add this restriction (i.e. each user has to save ejs file under his/her particular directory) to prevent more than one user upload different simulation with the same file name (it would overwrite previous file which will produce some trouble).
The upload ejs jar file only support ejs source file being save under users/ sub-directory.
This will also prevent confusion when two user share simulation with the same file name.

P.S. the problem you reported:"missing the thumbnails image" is fixed now.  :D

no problem, it was my oversight

awesome! this makes populating the forum useful to find simulations for all ejs users!
