I am trying to use the TopologyAnalyserPlugin class in my java code. I am tryinng to learn from one of the examples from chemAxon website. However I am getting an error which says


Exception in thread "main" chemaxon.license.LicenseException: No license file found.


Product Name: Geometry Plugin Group


I am a bit confused here. I can use the member functions of TopologyAnalyserPluginTopologyAnalyserPlugin class (eg bondCount) using cxcalc. Therefore I am not sure why I have problem with the license file. Can you please help me to solve this problem? Talking to guys here, I found out that we should have all the licenses form ChemAxon.


Cheers,


Sandeep

Hi Sandeep,


I have moved the toptic to the "License issues" section.


You can find the license installation instructions here:


http://www.chemaxon.com/marvin/help/licensedoc/install.html


Please note that there are multiple instructions, depending on the way of usage (desktop GUI, server applications, etc), and the user executing the application is also relevant.

Certain calculations may be allowed free wihtout a license.


Chemical Terms expressions ("evaluate", Evaluator class) use many of the same calculations.


There is a nice tabe for Cehmical Terms showing all calculations and their licenses.


As you can see a simple bondCount does not need a license:

Usually it's the easiest to check installed licenses via running License Manager ("licenese") with the same user as executing the Java program.


If you cannot solve the problem, please locate and send us the license file to our technical support e-mail address listed here:

The location os the license file is usally listed in the stack trace.


Please paste the full stack trace too, as well your exact JChem version.


Best regards,
