A. Background
may allow malicious Java code to execute unauthorized commands. Since
no permission is granted by default, the circumstances necessary to
exploit this vulnerability are relatively rare. On the Java
Development Kit 1.1.x (JDKTM 1.1.x) (browsers included), an applet must
be signed to have execute permission (signed applets may execute
anything in JDK 1.1.x.).

1.) HP-UX: Determining Java version information for JDK, JRE
-------------------------------------------------------------------------
There are two mechanisms to determine which versions of the Java
JDK/SDK (developer kit), JRE (runtime), or JPI (Java Plugin for
Netscape) you have installed. First, you can use the following
command to list the bundle revisions for any installed Java
products:
/opt/java - for Java 1.1
/opt/java1.2 - for Java 1.2
/opt/java1.3 - for Java 1.3
installed.
2.) HP-UX: Determining Java version information for JPI

you will need to check its version using the following.
$HOME/.netscape/java/bin/java -version
