One solution might be to add an additional command to "exec" where you set the path ... as in the example found here: http://www.neowin.net/forum/topic/620450-java-runtimegetruntimeexec-help/

excerpt:

            cmd = new String[7];
            cmd[0] = "cmd"; 
            cmd[1] = "/C";
            cmd[2] = "set PATH=C:\\Program Files\\Java\\jdk1.6.0_04\bin";
            cmd[3] = "copy " + "\"" +path + "\\" +name+ "\"" + " C:\\java";
            cmd[4] = "chdir C:\\java";
            cmd[5] = "javac *.java";
            cmd[6] = "jar cmf mainClass.txt"+" name"+".jar *.class";

            try{
            Runtime.getRuntime().exec(cmd);
