Contents:

 

 

1. General information

Two implementation variations of the Java Runtime Environment are available.
The "green threads" implementations use their own mutlithreading, and the "native threads" implementations use the multithreading mechanism of the underlying operating system.

 

2. Package contents

the package for HP-UX, based on the green-threads implementation of the JRE

  • hwjvfLINgrn.tgz

the package for Linux, based on the green-threads implementation of the JRE

  • hwjvfSUNnat.tgz

the package for Sun Solaris, based on the native-threads implementation of the JRE

  • hwjvf.exe

the installation program for Win32, based on the native-threads implementation of the JRE

  • hwjvf.pdf

3. Requirements

3.1. Sun Solaris

Operating System Versions: Solaris 2.5.1 and above.

JRE-Version: use the packaged Version of the JRE, which can be 1.1.8 and above.

For requirements specific to the Java Runtime Environment for Sun, read the information provided on

and the information shipped with the JRE itself:

The last file includes essential information about operating system requirements.

3.2. HP-UX

Operating System Versions: HP-UX 10.20 and 11.00

JRE-Version: use the packaged Version of the JRE, which can be 1.1.7 and above.

For requirements specific to the Java Runtime Environment for HP, read the information provided on

and the JRE release notes shipped with the JRE itself:

 

3.3. Linux/i386

Compatibility: glibc 2.1.x and XFree386 Version 3.3.x

JRE-Version: use the packaged Version of the JRE, which can be 1.1.7 and above

 

3.4. Win32/i386

Operating Systems: MS-Windows 95 / 98 / NT4.0.

Note: The JRE requires two additional components to be installed:

 

4. Installation

The installation packages include the JVF application plus a "private" Java Runtime Environment, which is installed into a subdirectory of the installation-directory you chose.

4.1. UNIX

Note: It is recommended to set the access rights of the .hwjava directory to read/write access only for the owner. (e.g. chmod 700 .hwjava)

 

4.2. Windows

Run the installation program hwjvf.exe and follow the steps prompted by the installation wizard.

 

5. Tips and tricks

5.1. Using HGCSP for better performance

  If you are not working behind a firewall and you do not connect over a proxy you can configure your server entries to use port 418 (HGCSP connection). This will speed up working with the Java Virtual Folders and decrease network traffic to the Hyperwave Information Server.

 

6. Known issues

6.1. HGCSP server connection timeout

  After 24 hours of inactivity the HGCSP connection will be closed and will not be restored automatically by the following requests thus leading to error messages. You may remove the server and add it again or restart the Java Virtual Folders to reestablish the connection.

6.2. Memory usage

The JVF perform caching for server-objects, which requires significant amounts of memory. The memory limit for the JVF is defaulted to 48MB. If you observe problems due to insufficient memory you can increase the value associated to the parameter -mx by modifying the wrapper-script (UNIX) or the shortcut (Win32). The value -mx32m (e.g.) corresponds to a limit of 32MB.
