[SOLVED] Unresolved import of external library with properties file in classpath

Unresolved import of external library with properties file in classpath

I'm working with usb4java at the high level following this demo: http://usb4java.org/quickstart/javax-usb.html. My issue is that we need javax.usb.properties in the classpath, so I've put it in the src directory. I've also loaded up the .jars into a lib directory and added them to the referenced libraries. After all of this when importing "javax.usb.*" I'm getting an import cannot be resolved error and none of the types are accepted.

Note: the properties file is populated with: "javax.usb.services = org.usb4java.javax.Services" as instructed.

Thoughts?

Solution

I think you need to add to the CLASSPATH also the JSR080 (javax.usb API). Where the javax.usb interface is defined. You can download from here: http://javax-usb.sourceforge.net/

I have checked and it looks the javax.usb API is included under lib folder in the usb4java-javax distribution: http://nexus.ailis.de/content/groups/public/org/usb4java/usb4java-javax/1.2.0/usb4java-javax-1.2.0.zip it is called usb-api.jar

Then make sure the javax.usb.properties file is on the root of your application CLASSPATH.
