calling the calculator from Java

I am trying to call the chemaxon calculator from java

The following code works perfectly:

String[] args = {inputName, "logp"};
chemaxon.marvin.Calculator.main(args);

However i can't find the correct arguments to make it save the output to a file. The following fails:
        String[] args = {"-o "+ outputName, inputName, "logp"};
        chemaxon.marvin.Calculator.main(args);

Although the following shell command works fine:

cxcalc -o results.sdf molecules.sdf logp

Any idea about how to pass the -o argument to the chemaxon.marvin.Calculator.main or at least how can i capture the output of the calculator?

 

I forgot to mention that when i try to execute the aforementioned        String[] args = {"-o "+ outputName, inputName, "logp"};
  

I get the following errors:
java.io.FileNotFoundException: -o /Users/path/to/my/output/results.sdf (No such file or directory)

It seams that the class doesn't undestand the -o argument and just treats it as a part of a filename

In case anyone else is following the thread without posting, i was able to find the correct arguments:

String[] args = {"-o", outputName, inputName, "logp"};

Hi,

Sorry, this topic escaped our notice.

FYI: calculator plugins have their own Java API, see e.g. the logP plugin API: http://www.chemaxon.com/marvin/help/developer/beans/api/chemaxon/marvin/calculations/logPPlugin.html
