You can specify a classpath either in the javac command or in the CLASSPATH system environment variable. Your classpath contains the MATLAB javabuilder library JAR file and the JAR files for the packages containing your compiled MATLAB code.

The JAVA_HOME environment variable is set to the folder containing your Java installation.

Running unsupported operating systems, particularly one as prevalent as Windows XP, create a very significant risk to users of these systems as vulnerabilities are widely known, exploit kits routinely available, and security patches no longer provided by the OS provider.Your development system uses a version of the Java Developer’s Kit (JDK™) that is compatible with MATLAB. Oracle also recommends Windows XP users to upgrade to a currently-supported operating system. Oracle recommends that home users visit to ensure that they run the most recent version of Java. 7 other Java SE client vulnerabilities receive a CVSS Base Score of 9.3 (denoting that a complete compromise of the targeted client is possible, but that that access complexity to exploit these vulnerabilities is “medium.”) All in all, this Critical Patch Update provides fixes for 17 Java SE client vulnerabilities, 1 for a JSSE vulnerability affecting client and server, and 2 vulnerabilities affecting Java client and server.

This score affects a single Java SE client vulnerability (CVE-2014-4227). The highest CVSS Base Score for the Java vulnerabilities fixed in this Critical Patch Update is 10.0. This Critical Patch Update provides 20 additional security fixes for Java SE.
