The Java Virtual Machine

In this page you can set the parameters for the Java Virtual Machine.

Settings

JVM parameters

This is an optional field. You can easily specify the JVM parameters. Click on the [ ... ] button in order to go to the Edit JVM Parameters Dialog.

JVM type

There are two types of JVMs: client and server. You can choose one of the following combinations:

• Favor client - Advanced Installer looks for client or server JVM in the JDK or JRE installed on your computer. It returns the JVM with the highest version (client or server). The client version is favored in the sense that the client JVM is looked up first, and if it is found, the search stops. This is the default option for JVM type.
• Favor server - Advanced Installer looks for server or client JVM and returns the server JVM with the highest version ( if it is found ). The server version is favored in the sense that the server JVM is looked up first, and if it is found, the search stops, otherwise the client JVM is looked up.
• Server only - Advanced Installer looks only for the server JVM If it is not found then the user is prompted to browse a JRE with a valid server JVM.

Virtual Machine Source

Specify the source of the Java Virtual Machine.

• JRE or JDK - either the JRE or JDK will be used.
• favor JRE - the JRE will be preferred. It will be looked up first.
• favor JDK - the JDK will be preferred. It will be looked up first.
• only JRE - the JRE will be used.
• only JDK - the JDK will be used.

Stream redirection

Output Stream to

Specify the location of the file that will contain the output steam of the Java Products. This field is of Formatted Type. Use the [ ... ] button to display the Edit Formatted Type Dialog that will allow you to insert a reference to a file, folder or property.

Error Stream to

Specify the location of the file that will contain the error steam of the Java Products. This field is of Formatted Type. Use the [ ... ] button to display the Edit Formatted Type Dialog that will allow you to insert a reference to a file, folder or property.

Java Library Path

You can modify the Java Library Path system property by adding values to this list.

By default Advanced Installer includes the following items in the Library Path property:

• the current directory
• the "Path" environment variable
• the loaded JRE \ lib directory

If you need to load a library from a different location you have to include it in this list. All the values you specify will be placed in beginning of the above list. Use the [ Folder... ], [ Property... ] or [ Env Var... ] button to add a path. Click the [ Env Var... ] button to select an Environment Variable using the Environment Variable Picker Dialog.

System Library Path

By adding values to this list, you can add paths to the default value of the Path system variable when this Java product is launched. This is useful when a library that you are using is trying to link to other libraries. These are searched using the values in the Path system variable. The locations that you add to the Path variable will have the biggest priority. So, if a library is presend in more locations then the search algorithm will prefer the location specified in that list.

The default value of the Path system variable will not be changed for other applications.
