I have added chemaxon jars to my project.I have academic  license file provided by my institute .How should i provide this license file in my portlet.So that at time of execution it may get the license file.I tried passing it as lib but its not working.Also i tried adding the following code to my portlet:

chemaxon.license.LicenseManager.setLicenseFile(PATH).But it is still not working

Right now i m getting the following error:

chemaxon.license.LicenseException: No valid license has been found.

Supposedly, that's an error with the version of xerces that Liferay ships with (reference), and so the workaround recommended there is to add the indicated system property (if you're using Apache Tomcat, you can add it alongside all the other -D settings in setenv.sh and setenv.bat) so that it uses the JDK built-in schema validation.

I think there's something lost in translation. Did you already add the environment variable mentioned in the link I posted earlier?

-Djavax.xml.validation.SchemaFactory:http://www.w3.org/2001/XMLSchema=com.sun.org.apache.xerces.internal.jaxp.validation.XMLSchemaFactory
