如何使Java查看文件的特定位置

Question

I'm creating a Jar file which automatically creates a target folder.

Within the the target folder I have an XSD file. When I execute the jar file via the command prompt - it is looking for the file in the target folder as opposed to the test-classes folder.

Is there anyway I can configure this so that the compiler looks at the test-classes folder for the file?

Thanks

The "test-classes folder" is just a random place on your hard disk.

Java supports 3 generic places to look for resources:

1. the current working directory . this is where your command prompt is.

2. the user home This is what you get when calling System.getProperty("user.home") . On Unix this resoves to $HOME and on Windows to %USERPROFILE%

3. the own code location . Resources in the same package as your class are accessed with getClass().getResource("filenameWithoutPath") But usually you place resources in a special folder in the application root and access it like this: getClass().getResource("/relative/path/from/src/root/filenameWithoutPath")
