Change the JRE

The FileXpress Transfer Server and FileXpress Gateway Administrator are Java applications. A correctly configured Java Runtime Environment (JRE) is installed and used by default. Use the procedures below to configure these services to use a different JRE.

Notes:

  • Each time you upgrade your JRE, you need to apply the unlimited strength policy files to the new JRE.
  • Each time you upgrade FileXpress Gateway or apply a hotfix, you need to repeat the changes to the properties files.

Install a Java JDK from the Oracle site

  1. Go to the Java SE Downloads page.
  2. Download and install the JRE using either the JDK download or the Server JRE download.
    • Download the latest Java 7 update. Java 8 is not supported.
    • The Server JRE is recommended. This download does not include the browser plug-in. Because this plug-in is where most of the security vulnerabilities are found, using this download helps reduce your security risk.

 

Note: Updates to JREs you download this way are not automatic, and each update uses a new, version-specific folder (for example C:\Program Files\Java\jdk1.7.0_<nn>\jre).

Apply the Unlimited Strength Jurisdiction Policy Files to your JRE

  1. Go to the Java SE Downloads page.
  2. Download the Java Cryptography Extension (JCE) Unlimited Strength Jurisdiction Policy Files.
  3. Unzip the downloaded file and locate the following two policy files:

    local_policy.jar

    US_export_policy.jar

  4. Locate the security folder in the Java install you want to use (<java-home>\jre\lib\security).
  5. Replace the limited strength policy files in that folder with the unlimited strength policy files.

Note: You need to repeat this procedure each time you upgrade your JRE.

Edit the properties files and restart the servers

  1. Locate the configuration properties file (container.conf) for both the Gateway Administrator and the Transfer Server:

    <install path>\GatewayAdministrator\conf\container.conf

    <install path>\TransferServer\conf\container.conf

  2. Open each of these files in a text editor and locate the wrapper.java.command parameter. Edit this parameter to specify the full path to the java command (without the .exe extension) in your JRE. For example:

    wrapper.java.command=C:\Program Files\Java\jdk1.7.0_<nn>\bin\java

  3. Restart the Gateway Administrator Server and the Transfer Server.

Note: You need to repeat this procedure each time you upgrade FileXpress Gateway or apply a hotfix.
