Java Runtime Environment (JRE) 1.1.8 IBM build n118p-19991124 refreshes the
Java Virtual Machine and supporting code that is used by Client Access Express and
Operations Navigator.
 
Applying this PTF will place the Java Runtime Environment (JRE) fixes and supporting
install files in AS/400 directory \QIBM\ProdData\CA400\Express\Service\JRE automatically.
 
If the JRE service pack is received from a web download, the customer must place the
self-extracting JREV4R51.exe file in an empty directory, and run JREV4R51.exe to
unpack the JRE fix files into this directory.  You can then delete the JREV4R51.exe
file to save space, as it is no longer needed.
 
Client Access Express CheckVersion (either Login Service Check or the Check Service
Level shortcut in the Client Access Express Service folder) will detect any new JRE
level on the AS/400 in directory \QIBM\ProdData\CA400\Express\Service\JRE and update
the client PC automatically.
 
The JRE service pack can also be installed by running setup.exe from the
\QIBM\ProdData\CA400\Express\Service\JRE directory (or wherever the service pack
web download was unzipped to).
 
Installing the JRE service pack on Windows NT/2000 requires Administrator authority
on the PC.
 
To prevent users from installing the JRE Service Pack, an administrator can set the
Install Service Pack policy restriction, or can use the SP.TXT file.  If the
administrator places a file named SP.TXT (with a 'N' in the first position of
the first line)in the JRE service pack installation image directory, the service pack
will not be installed.
