X64 java 1.4.2_18 for SAP

Hello Basis. I'm install yesterday new SR3 Netweaver AS JAVA (Portal+BI).
On installation stage I have faced a problem....
OS are Windows x64 -->
System Model:         PowerEdge 2950
System Type:           x64-based PC
Processor(s):            8 Processor(s) Installed.
                                EM64T Family 6 Model 15 Stepping 7 GenuineIntel
First i'm download and install J2SE per note Note 941595 - Download J2SE 1.4.2 for the x64 platform
Java SE Development Kit 1.4.2_18 x64 SAP .
On installation stage "Install software units" 32 of 43 -->
installation hangs with message :
"Begin of SAP J2EE Engine Deployment (J2EE Application)"
no errors no other logs , and in sapinst_instdir no files are changed on 3-4 hours ......
I have formatted system, and try NEW installation, install same version of J2SE -->
on this time , installation stops on stage "start java application" , but jcontrol.exe are shutdown after start, from log i'm find the error comes from J2SE, uninstall 1.4.2_18 and install 1.4.2_13 -->
after this installation has proceeded and has ended without errors.
Somebody observed same?
Regards.

Dear
Yes
You can find the information in SAP note 716604
Note 716604 - Access to Sun J2SE and recommended J2SE options
"part of the note:"
Important note:
With 1.4.2_18 we are currently having massive stack overflow problems on Windows x86 (64bit) with our default parameter set. The issue is still under investigation. Additionally we have a performance regression with Java Systemcopy on 1.4.2_18.
Until further notice please don't use 1.4.2_18.
In the meantime SUN has made available 1.4.2_17 for Windows x86 (64bit) and Solaris x86 (64Bit) for download. Please see note 941595.
Kind regards

"Java and BAPI Technology for SAP" by by Ken Kroes - Is this book useful?

Howdy partners,
I've got a 'book' called "Java and BAPI Technology for SAP" by by Ken Kroes, Anil Thakur, Gareth M. deBruyn, Robert Lyfareff.
Now, does anyone know if the info in this book is still relevant to the modern SAP world? I mean its still talking about ITS and stuff like that?
Any input will be appreciated.

With the blue cover? I have one with the something similar title, but it's quite out of date. There was lot of improvement on the Java side.
So I would prefer something newer from SAP-PRESS. Check the SAP-PRESS site.
BTW I don't consider ITS as an old technology...it was just integrated recently into WAS 640 to make it more powerful. This is the only available technology, which converts classic Dynpro to Webpage dynamically.

What is the Java runtime version required for SAP GUI 6.20 for Windows?

Hi All,
I need the following information:
1. What is the Java Runtime version required for SAP GUI version 6.2 for Windows (Platform Windows XP)?
2. And is there any problem if we use Java runtime version 1.6 on PC?
It would be great if anybody can provide the information on the above.

To run SAP GUI for WIndows -- Java isnt a pre-requisite nor is there any dependency for the same.
Thanks,

Creation of "Web Dynpro for Java" for SAP transaction

Hi All,
In EP when we create SAP transaction iView for SAP transaction,
a)ITS server is required if we choose SAP GUI Type as WebGui(Performance wise as well as some other issues)
b)SAP GUI has to be installed if we choose SAP GUI Type as WinGui.(User has to install SAP GUI).
Can we overcome these two issues by creating Web Dynpro application for SAP transaction in quicker way. Any suggestions are appreciated.
Thanks and Regards,
Gangadharayya.

Hi,
It is not possible to display a transaction directly in a java web dynpro. If you do not want to use a transaction iview the only other possibility is to create a web dynpro that uses BAPI's as models.

Hello,
I install EHP1 FOR SAP SRM 7.0 JAVA system and now I what create this system in SAP Support Portal.

If I select SAP SRM, in version I don't have option to select SRM 7.0 EHP1 and no Technical usage to select.
If I select SAP Netweaver, in version I have SAP Netweaver EHP2 and I can select Technical usage "Application server java" and "EP Core" but not SRM java.
In Solution Manager I have the same problem, what products shoul I select to create this system in SMSY?

Dear Rolf-Martin,
I have problem w/ sapgui java that puzzled me all along ...
I've downloaded SAPGUI Java 700r2.1 .. then successfully installed in my PPC ibook G4 ... up and running well ...
one day my colleague with a new MacBook (Intel Core Duo 2GHz) want to have SAPGUI ...
i installed it, run the apps, it works well to the point of SAPLOGON window ...
But it cannot connect to any server defined ...
When I create a new connection, it correctly connected to server and group list can be chosen, but still when I click it to connect nothing happened as if the program not running.
Java -version is 1.5.0_07 .. software update checked, no issue with Java or else ...
I've also try to change the JDK to 1.4.2 to no avail.
I'm stuck. system already re-installed. install sapgui from fresh but problem still persist.
No clue from Googling ... no clue from sapnotes ...
Would you please point me to something so I can dig in ?

Is Firefox x64 (Minefield) for Windows compatible with the x64 Java 7 Beta?

Firefox x64 (Minefield) on Windows 7 crashes with the Beta x64 Java 7 (it works on 64 bit windows, and the 32 bit java 7 works in 32 bit firefox). It works fine with any newer version of Java 6 x64 however. Is this a firefox or Java bug?

I was having this problem myself until just recently.
However, it works for me with the following:
Nightly x64 6.0a1 builddate 05222011 and
Java 7 x64 b143
Earlier versions causes crashes, so try updating to the latest JRE7 and the latest Nightly.
