javac: invalid flag error when using arguments

Disclaimer: I am NOT a Java developer.

I have a shell script that passes variables into my java program.

#!/bin/bash
$JAVA_HOME/javac -classpath $clp myjavaapp.java "$1" "$2" "$3"

When I run this script I get the following error:

javac: invalid flag: /public/rest/api/1.0/cycles/search?versionId=-1&projectId=10005
Usage: javac <options> <source files>
use -help for a list of possible options

Where /public/rest/api/1.0/cycles/search?versionId=-1&projectId=10005 is the value passed it at $3.

Here is a sample of the contents of my myjavaapp.java file:

package myjavaapp;

...

public class myjavaapp {

    public static void main(String[] args) throws URISyntaxException, IllegalStateException, IOException {

      ...

      String variable1 = args[0];
      String variable2 = args[1];
      String variable3 = variable2 + args[2];

      ...

    }

}

What am I doing wrong? Am I using the arguments correctly?

The problem is probably the value of the $clp variable that is /public/rest/api/1.0/cycles/search?versionId=-1&projectId=10005 and that is not a valid option for javac.
Check its value first.

Then, the passed arguments "$1" "$2" "$3" makes no sense :

$JAVA_HOME/javac -classpath $clp myjavaapp.java "$1" "$2" "$3"

The javac command is for compiling class(es), not for running applications.
You probably mixed it with the java command that allows to run a executable class (application) and that accepts args.
