The Java Tab

The Java tab allows you to configure Java features in iPlanet Web Server. The Java tab contains the following pages:

• The Enable/Disable Servlets/JSP Page

• The Configure JVM Attributes Page

• The Delete Version Files Page

The Enable/Disable Servlets/JSP Page

---

The Enable/Disable Servlets/JSP page allows you to enable and disable Java features such as web applications, servlets, and JavaServer Pages (JSP).

For information about how to configure web applications in iPlanet Web Server 6.0, see Working with Web Applications.

The following elements are displayed:

Enable/Disable Java Globally. Enables or disables support for Java features for the entire server instance.

Virtual Server Class. Lists the virtual server classes.

Enable/Disable Java. Enables or disables support for Java features for a virtual server class.

OK. Saves your entries.

Reset. Erases your changes and resets the elements in the page to the values they contained before your changes.

Help. Displays online help.

The Configure JVM Attributes Page

---

The Configure JVM Attributes page allows you to set parameters for the Java virtual machine (JVM).

For more information, see Configuring JVM Attributes.

The following elements are displayed:

Option. Specifies any options allowed by the vendor's JVM.

OPTITDIR. Specifies the absolute path for the directory where Optimizeit! resides, for example, D:/App/IntuitiveSystems/OptimizeIt30D if you are using the Optimizeit! 3.0 profiler from Intuitive Systems.

Classpath. Specifies the Java classpath where the classes for the servlet engine are located and any additional classpath information needed by servlets or JSP. For example, if a JSP uses a bean that is packaged in a JAR, add the JAR path to the classpath. You can add values to an existing classpath, but do not delete values from a classpath.

Profiler. Specifies a value for the optimizer. Enter "optimizeit" if you are using the Optimizeit! 3.0 profiler from Intuitive Systems.

Minimum Heap Size. Specifies the minimum heap size for the interpreter.

Maximum Heap Size. Specifies the maximum heap size for the interpreter. This setting has the same fuctionality as the command-line option -mx in Java.

Enable Class GC. Specifies whether or not to enable class garbage collection.

Verbose Mode. Specifies whether the logging collection (if enabled) will be in verbose mode.

Enable Debug. Enables remote debugging.

Enable JIT. Enables the Java compiler.

OK. Saves your entries.

Reset. Erases your changes and resets the elements in the page to the values they contained before your changes.

Help. Displays online help.

The Delete Version Files Page

---

The Delete Version Files page allows you to delete the files that contain the version number for the session data cache and JavaServer Pages class cache. When the server detects these files during start-up, it checks the version, and if the current version is lower than it is supposed to be, it deletes the current directories and creates new ones.

For more information, see Deleting Version Files.

The following elements are displayed:

Clear Session Data. Deletes the version file for the session data. When you apply this change, the version file is deleted immediately. The next time the server starts up, it deletes the session data cache and recreates the version file. The next time the server serves a JSP or servlet while using the MMapSessionManager session manager, it recreates the session data cache.

Delete JSP ClassCache Files. Deletes the class cache version files for JSP. When you apply this change, the version file is deleted immediately. The next time the server starts up, it deletes the JSP class cache and recreates the version file. The next time the server serves a JSP, it recreates the class cache if necessary.

OK. Saves your entries.

Reset. Erases your changes and resets the elements in the page to the values they contained before your changes.
