| Release: |
V4R5M0 |
Introduction
This document describes what you need to do to get JDK 1.3
(also known as Java 2 version 1.3) operational on your iSeries 400
or AS/400e server. This information is contained in 5769JV1 PTF
SF63319 which can be ordered from Boulder,
Colorado.
Before You
Begin
In order for JDK 1.3 to work on
your server, you must first have V4R5M0 installed with PTF CUM
package C0189450 or later. You must also have 5769JV1 Option *BASE
installed. You may then optionally install option 3 (JDK 1.2) and/or
option 4 (JDK 1.1.8).
Since some Java
applications may not work with JDK 1.3, you may want to have one of
these options installed. For example, the current version of
Websphere requires JDK 1.2.
Follow the
instructions below to install the Java group PTF and 5769JV1 Option
5.
It is very important that you install
the Java group PTF before you install option 5. Do not install
option 5 until you have the correct level of the Java group PTF
installed.
Java Group
PTF
Order and install the Java group
PTF, SF99068. Follow the instructions included with the group PTF.
Use the following command to verify that the correct level of the
group PTF has been installed:
DSPDTAARA QJAVA/SF99068
Output
will show Group PTF#:
SF99068-01 or later, along with a
date.
To install the group PTF do the
following:
| 1 |
On an OS/400 command line, type
the following:
GO
PTF
Press the Enter
key. |
| 2 |
Select option 8. |
| 3 |
Specify PTF type 1 (all PTFs) and
automatic IPL Y. |
Install 5769JV1 Option
5
JDK 1.3 is product 5769JV1 Option
5. This is contained in 5769JV1 PTF SF63319. You will need to order
this PTF. It will be sent to you on a CD. Read the cover letter; it
contains additional information.
Load the
CD containing the PTF in the drive and enter the
following:
RSTLICPGM LICPGM(5769JV1) OPTION(5) DEV(OPTxx)
where OPTxx is the ID of your CD
drive.
Set up Symbolic
Links
In JDK 1.3, functions like
JDBC, SSL, and JNDI are JDK extensions. To use a JDK extension,
first find the .jar
file in the '/QIBM/ProdData/Java400/ext/' directory. Then, a
symbolic link needs to be established once to make the files a part
of the '/QIBM/UserData/Java400/ext/' directory. This is so that the
class loader can find them. For example, to establish the symbolic
link for JDBC, use the following command:
ADDLNK
OBJ('/QIBM/ProdData/Java400/ext/db2_classes.jar')
NEWLNK('/QIBM/UserData/Java400/ext/db2_classes.jar')
Other non-IBM provided extensions
(in .jar files) can be loaded directly into the
'/QIBM/UserData/Java400/ext/' directory.
Verify the Functionality of JDK
1.3
Use the following command to
verify that JDK 1.3 is working on your system:
JAVA
CLASS(com.ibm.as400.system.Hello) PROP((java.version
1.3))
A screen should be displayed
that shows the following:
Hello
World
Java program completed
Press the Enter key on this screen to
return to the OS/400 command entry screen.
If this command does not work, then you need to contact your
service representative for help in getting JDK 1.3 to work on your
system.
Using JDK 1.3 on
Your Server
In V4R5, 5769JV1 supports
Options 1-5. The default JDK used on the system is listed by order
of preference below.
| 1 |
Option 3 (JDK 1.2) |
| 2 |
Option 5 (JDK 1.3) |
| 3 |
Option 4 (JDK 1.1.8)
|
| 4 |
Option 2 (JDK 1.1.7)
|
| 5 |
Option 1 (JDK 1.1.6)
|
For example, if the server has all five supported
options installed, Option 3 (JDK 1.2) is the
default.
To force the use of JDK 1.3 when
using JAVA, you will need to specify the 'java.version=1.3' property
as in the Verify example above.
To make
JDK 1.3 the default when JDK 1.2 is installed, set the java.version
property to 1.3 in the SystemDefault.properties file. (for example,
specify java.version=1.3 inside the file). The SystemDefault.properties file is not
shipped as part of the JDK 1.3 LPP; it is a text file that is
created by the user. There are two places the file can be
placed:
User Home :
/home/userid/SystemDefault.properties
Java
Home :
/QIBM/UserData/Java400/SystemDefault.properties
The priority in which properties are used is:
| 1 |
User specifies on the JAVA
command |
| 2 |
User Home |
| 3 |
Java Home |
| 4 |
environment
variable |
It is advised to place the SystemDefault.properties
only in your User Home, as placing it in Java Home will cause
all users on the
systems to pick up the values in this file, whether they want to or
not.
