Using the Java Development Kit 1.2:
 
 
   Before using the JDK or JRE, please verify that the patches required
   for your version of Solaris are installed.  The required patches are
   listed above in the Requirements section.
 
   The easiest way to run JDK 1.2 is to update the PATH environment
   variable in your shell by placing the path to the java executables at
   the front, before /usr/bin.  For example, if the JDK is installed in
   /opt/java/java1.2,
 
       (csh)       setenv PATH "/opt/java/java1.2/bin:$PATH"
 
       (sh or ksh) PATH="/opt/java/java1.2/bin:$PATH"
 
   Alternatively, the executables may be run by specifying the full path
   name, e.g., /opt/java/java1.2/bin/javac, /opt/java/java1.2/bin/java, etc.
 
   See the section in the Release Notes titled "Running with Both JDK
   1.2 and JDK 1.1" for information regarding making JDK 1.2 the default
   on your system.  If JDK 1.2 is made the default, then the above
   changes to the PATH environment variable are no longer necessary.
   However, compatibility reasons may necessitate keeping JDK 1.1 as the
   default JDK.
 
   No other environment variables (such as JDK_HOME, JAVA_HOME or
   CLASSPATH) are required to run the JDK.  However, existing settings
   of these variables may result in improper operation and should be
   checked for possible conflicts.
