OrbixWeb3.1c and Java2.1 revisited

[Bart Dannis]

Hi!

I am working with OrbixWeb 3.1c and JDK1.2 on WinNT4. When I start the
OrbixWeb Java Daemon (Orbixdj), I get the following error message:

java.lang.NullPointerException: Null output stream
at java.io.PrintStream.<init>(PrintStream.java:81)
at java.io.PrintStream.<init>(PrintStream.java:63)
at
IE.Iona.OrbixWeb.Activator.GuiConsolePrintStream.<init>(GuiConsolePrintStrea
m.java:15)

at IE.Iona.OrbixWeb.Activator.orbixd.setupConsole(orbixd.java:194)
at IE.Iona.OrbixWeb.Activator.orbixd.main(orbixd.java:35)

I read more messages on this subject and I tried the proposed solution to
include the "Xbootclasspath" parameter. So, I edited orbixdj.bat as follows
(all software is installed in default directories):

set |
owjava -Xbootclasspath:C:\Iona\OrbixWeb3.1c\classes;C:\jdk1.2\jre\lib\rt.jar
-Dorbixweb.server_name=IT_daemon -Dorbixweb.server_comms=tcp -Dorbixweb.ser
ver_code=xdr IE.Iona.OrbixWeb.Activator.orbixd %1 %2 %3 %4 %5 %6

But the same error occurs.

Can somebody help me with this problem?

Regards,
Bart

There are _big_ problems with JDK 1.2, it seems, and I mean showstoppers.
Inprise says "Stay with 1.1.*," Iona says "You want 1.1.5 or 1.1.7," there
are reports of trouble with callbacks in 1.2, and so on.

I don't know if this error is related, but you should downgrade anyway.

Hope this helps...

An alternative approach is to use jdk1.1.x for the OrbixWeb daemon, and the
other utilities, but to use jdk1.2 for your own applications.

method:

1. define the following Environment Variables at system level:

ORBIXWEB_HOME=<install dir of OrbixWeb, e.g. c:\iona\orbixweb3.1c>
JDK1_1_HOME=<install dir of jdk1.1.x, e.g. c:\jdk1.1.7b>
JDK1_2_HOME=<install dir of jdk1.2, e.g. c:\jdk1.2>

2. use jdk1.1.x for Orbixdj, and other OrbixWeb3.1c utilities

OrbixWeb provides two executables that wrap jdk utitilities
owjava.exe && owjavac.exe

replace owjava.exe with a .bat file like the following:

<owjava.bat>
@echo off
set JAVA=%JDK1_1_HOME%\bin\java.exe
set ORBIX_CLASSES=%ORBIXWEB_HOME%\classes
set JDK_CLASSES=%JDK1_1_HOME%\lib\classes.zip
set ORBIX_DEF=OrbixWeb.config=%ORBIX_CLASSES%\OrbixWeb.properties

set OWJAVA=%JAVA% -classpath %ORBIX_CLASSES%;%JDK_CLASSES% -D%ORBIX_DEF% %*

echo %OWJAVA%
%OWJAVA%
<end owjava.bat>

and owjavac.exe with owjavac.bat, so that applications use the Jdk 1.2
compiler

<owjavac.bat>
@echo off

set JAVAC=%JDK1_2_HOME%\bin\javac.exe
set ORBIX_CLASSES=%ORBIXWEB_HOME%\classes
set JDK_CLASSES=%JDK1_2_HOME%\jre\lib\rt.jar

%JAVAC% -bootclasspath %ORBIX_CLASSES%;%JDK_CLASSES% %*
<end owjavac.bat>

getting OWConfig to work using jdk1.1.x
edit OWConfig.bat
a. change all :: to % ( I presume owjava.exe interprets :: as % ? )
b. set JAVA_HOME=%JDK1_1_HOME%
used to locate content-type.properties
The new OWConfig.bat:

<OWConfig.bat>
@echo off
set JDK_CLASSES=%JDK1_1_HOME%\lib\classes.zip
set JAVA_HOME=%JDK1_1_HOME%
set CLASSPATH=%ORBIXWEB_HOME%\classes;%JDK_CLASSES%

owjava -classpath
"%CLASSPATH%;%ORBIXWEB_HOME%\tools\lib\bongo.zip;%ORBIXWEB_HOME%\tools\lib\ma
rim ba.zip;%ORBIXWEB_HOME%\tools\ConfigGUI\OWConfig.zip"
-DOrbixWeb.home=%ORBIXWEB_HOME% IE.Iona.OrbixWeb.ConfigTool.OrbixWebConfigApp
%* <end OWConfig.bat> (note: the line owjava ... %* should be on one line )

note: OWConfig hangs on exit when 'save before quit' is selected.

3. launching servers using jdk1.2 vm
in OrbixWeb.properties set the property
IT_JAVA_INTERPRETER=<full path to java.bat>
IT_DEFAULT_CLASSPATH=<application classpath>

<java.bat>
@echo off
set JAVA=%JDK1_2_HOME%\bin\java.exe
set ORBIX_CLASSES=%ORBIXWEB_HOME%\classes
set JDK_CLASSES=%JDK1_2_HOME%\jre\lib\rt.jar

set BOOTPATH=%ORBIX_CLASSES%;%JDK_CLASSES%
set PROPS=OrbixWeb.config=%ORBIXWEB_HOME%\classes\OrbixWeb.properties

set RUNJAVA=%JAVA% -Xbootclasspath:%BOOTPATH% -D%PROPS% %*

echo executing: %RUNJAVA%
%RUNJAVA%

<end java.bat>

4. starting clients
use java.bat
e.g.
java.bat -classpath f:\coghlang\classes ie.coghlang.bank.javaclient1

hope this helps,
regards,
Grainne

I believe this error is caused by orbixdj not being able to find the
swing classes. I believe it is attempting to locate them under com.sun
instead of javax. The following are a couple of things you might try ...

1. include both the Java 1.2 rt.jar and a jar with swing under com.sun
in your boot class path
2. start orbixdj with the -textConsole switch will start orbixdj without
a gui console window

hope this helps.
