Hi Lili,

I recommend putting this .module file in the externalModules directory. It should be a sibling to the modules and labkeywebapp directory. After creating the directory if needed and adding the apisamples.module, you'll need to restart Tomcat. The server will automatically extract any content into an apisamples subdirectory if needed.

For more information, please see this documentation page:

Thanks,
Josh
