path is where your executables are class files are in your classpath.
They are used in two ways - 1. While compiling, it should be there on the classpath - eg., set classpath=%classpath%;c:\jars\classes12.zip; Else the files dont get compiled. 2. While executing the file, it needs to be on the classpath too. For that u place it in jre\lib or on the server lib if u are using a webserver/app server.
sometimes, you also need to have the corresponding Oracle client installed on the machine for the proper execution of file.
