Hi All,

We are using Java Play Framework 2.2.3 with Java 1.7 (Open JDK 64 Bit) and Watson JAR. https://github.com/watson-developer-cloud/java-sdk/releases/download/java-sdk-2.8.0/java-sdk-2.8.0-jar-with-dependencies.jar

It compiles fine, but at run time gives error: Line 48 of the code referred to have a problem on execution: seems like class path error so we have made sure the class path is correct. But, still the error continues - are there other dependencies that we need to import to make this line work or any other suggestions?

 AlchemyLanguage service = new AlchemyLanguage();

in addition we are using getAlchemyKeyword & getAlchemyNews and all calls fail

Here is the error stack:
