How to Temporarily Include Jars in the Classpath for javac, ant, and java Commands?

Including Jars in Classpath on Commandline (javac or apt)

While attempting to execute a program, you may encounter compile errors indicating the absence of necessary jars in your classpath. One such jar is jsr181-api.jar, which is essential for web service functionality.

To avoid modifying your bash_rc file, you can temporarily include the required jar in your classpath. There are several ways to achieve this:

Using javac or ant

You can specify a list of jars to be included in the classpath using the -cp option:

$ javac -cp jsr181-api.jar HelloImp.java

$ ant HelloImp -cp jsr181-api.jar

Using the Java -cp Command

You can set the classpath using the -cp option of the Java command:

$ java -cp jsr181-api.jar:dir1:. server.HelloImp

In Windows, use a semicolon (;) instead of a colon (:) as the path separator.

Note: Ensure you include the current directory (.) in your classpath to access files in the current working directory.

By following these methods, you can temporarily include the necessary jar in your classpath without permanently modifying your environment.
