4. NETSCAPE/IPLANET PLUGIN (SPARC/SOLARIS)
ServletExec 4.1 Installation Guide 31
Important
The JRE does not contain a Java compiler, which is required by ServletExec to support
JavaServer Pages (JSP). Be sure to install the JDK, and not the JRE, if you plan to use JSP.
You can download the Sun JDKs for SPARC Solaris from:
http://java.sun.com/j2se/
Note
Sun has created two versions of the JDK for Solaris, which it refers to as the Production and
Reference implementations (or releases). We recommend using only the latest Production
release of the JDK with ServletExec/NSAPI. We do not recommend using Reference releases
of the JDK in production environments.
Important–iPlanet Users
Due to a bug in either iPlanet or the JVM which causes the JVM to hang under stress, we do
not recommend using JDK/JRE 1.3.x or 1.4.0 beta. Instead, we recommend using the latest
production release of JDK 1.2. This hanging problem only occurs with the ServletExec/NSAPI
on Solaris product.
4.2.2.1 Multiple JDK/JRE Versions Installed
You may have multiple versions of the JDK/JRE installed on your system. If the
installation script detects multiple versions, it will ask you to select which one to use.
Uninstalling Other Servlet Engines
Very Important
You must uninstall any other servlet engines previously installed for use with NES/iWS before
installing and using ServletExec/NSAPI. In particular, modifications to the obj.conf
configuration file for other servlet engines must be removed. In addition, you must disable the
NES/iWS built-in servlet support as described in the following sections before installing
ServletExec/NSAPI.
4.2.3 Deactivate the Java Interpreter (NES 3.5.1 and higher)
For NES 3.5.1 and higher, the built-in Java interpreter is deactivated by default. If,
however, it has been activated on your server you must deactivate it manually before
installing ServletExec/NSAPI.
To manually deactivate the Java Interpreter
1. From the Netscape Administration Server home page, click the appropriate server.
See the Netscape Administration Server documentation if you need help with this step.
2. Click Programs from the menu bar in the upper frame of the server
administration page.
3. In the menu in the left frame of the Programs page, click Java.
4. Turn off the Java interpreter.
