9IAS and Java 1.4.2_06

Hi all,
I have installed 9IAS and Java 1.4.2 on Solaris 8, as per Oracle's own documentation I have changed the JDK to point to my Java installation in /usr/j2se in order for out Java based application to work, however the EM process will now not start it time's out and aborts. This means I am unable to access the website I just recive an Internal Server error.
Any ideas on how to get Oracle to use the new Java?
Thanks.

Hi,
I had this same issue when upgrading from 9.0.4 to 10.1.2.2. Someone else in the forum had a solution. You could probably search for it. However, here are the details:
The fillowing are the notes from Oracle:
Applies to:
Oracle Discoverer - Version: 10.1.2.2 to 10.1.2.3 This problem can occur on any platform.
Symptoms
The user interaction performance using Discoverer Plus 10g (10.1.2) when configured with Sun java plug-in (JRE/JVM) 1.6.0_03 or higher.
Every action in Discoverer takes longer. For example:
displaying the Create/Open Workbook wizard
displaying the Help > About window.
The problem does not exist with JInitiator or with Sun plugin 1.4 or 1.5 and earlier versions of 1.6
JRE 1.6.0 - works correctly, runs with 1.5.0-like speed JRE 1.6.0_01 - works correctly JRE 1.6.0_02 - works correctly JRE 1.6.0_03 - here the problem is observed for the first time. The issue is then observed in all subsequent versions (e.g., _04, _05, _06, _07 and the new_10)
The problem does not exist when an entry for the Discoverer server exists in the local hosts file on the client PC (C:\WINDOWS\system32\drivers\etc\hosts).
Cause
Sun's Java plug-in performs reverse DNS lookups when connecting to the Application Server. This can be observed with a network sniffer trace (Wire Shark).
There is a change in the DNS handling in Sun plug-in 1.6.0_03 and higher.
This issue may be more prevalent if you are accessing Discoverer Plus via a firewall, proxy server
Solution
To implement the solution, please execute the following steps:
Ensure the external facing IP address of the Discoverer server has a reverse DNS entry in the DNS server.
For example:
nslookup <IP address> must resolve to the <machinename.domainname>
and
nslookup <machinename.domainname> must resolve to <IP address>
An alternative or temporary solution would be to add an entry to the local PC host file as described above.
Hope this helps,

Discoverer 10.1.2.48.18 and Java 1.4.2_06

Hi Discov Gurus,
We have discoverer Version 10.1.2.48.18 installed on the server. When some user wants to access discoverer reports he goes to Internet Explorer and gives the URL that points to discoverer PLUS.
DIscoverer PLUS works default with Java 1.4.2_06 but if the User PC has multiple Java or JRE versions the Discoverer Plus opens with New JRE version say JRE 1.6.0_06.
The problem is the Java Applet hangs sometime with the new JRE version. I cannot remove this new version of JRE as
some other applications need this new Version of JRE.
Question is how can i force discoverer to use the old JRE 1.4.2_06 version.
Thanks,

The required version of java ,1.4.2_06, is not the latest and may not conta

Hi
I've implemented SSL on Discoverer and it works fine,
the problem comes when discoverer laucnhes it pops up with this massage
the required version of java ,1.4.2_06, is not the latest and may not contain latest security updates.
I the click on yes, and then it takes about five minutes to work.
I followed metalink note 427930.1 and it did not help.
I'm busy going thru matalink note 290807.1
can someone please help.
Thanks

Change your formsweb.cfg to use JRE 1.6.0_27. It is not a good idea to use old JRE versions. Each new release includes bug fixes as well as security enhancements. Using old versions may leave your system at risk of exposing bugs and/or security vulnerabilities. Since Forms 11 is certified with 1.6.0_12 and supported with all 1.6.0_12+ versions, moving to the latest in the 1.6 series is a good approach.
Alternatively, disable the Autoupdate feature in the JRE, found on the JRE Control Panel.
For future reference, there is a Forum specifically dedicated to JRE issues/questions:

JNI MMX and Java long arithmetic

I am having trouble with a JNI call to a C program which contains assembler which uses an MMX operation as follows:
static inline int diffPixels(int rgb1, int rgb2) {
register int temp;
__asm__ __volatile__ (
"movd %1, %%mm1\n\t"
"movd %2, %%mm2\n\t"
"psadbw %%mm1, %%mm2\n\t"
"movd %%mm2, %0\n\t"
: "=r" (temp)
: "r" (rgb1), "r" (rgb2)
: "mm1", "mm2", "cc"
return temp;
After the JNI call returns, the first Java long arithmetic fails. I believe the failure is that when a method on a Java object returns a long the result is 0x8000000000000000 rather than the correct value.
To use pure Java means my response to a user action is 9 seconds rather than 3 seconds with the JNI call which is why I want to persist with it. At present I am doing an arbitrary long multiply after the JNI call to "fix" long arithmetic but I am afraid this won't work if there is a context switch to another java thread in the middle of the JNI call.
The test environment is a 3 Gigahertz Pentium 4 running Linux kernel 2.6.9 and Java version 1.4.2_06-b03.
Can anyone explain this behaviour ? It took me days to isolate the problem.

Hi,
Is it absolutely necessary to declare temp as register ?
How about adding a lock directive at the beginning of your asm ?

Whats is difference between Java JRE and Java SDK

Hi,
what is the difference between Java JRE and Java SDK...
i think both of them have the same set of files to be installed...
I am not able to understand where they differ

The JRE (Java runtime Environment) contains just the stuff necessary to run Java and the SDK (System Development Kit) contains the extra stuff necessary (and also helpful) to develop in Java.

What is difference between C# Gzip and Java swing GZIPOutputStream?

Hi All,
I have a Java swing tool where i can compress file inputs and we have C# tool.
I am using GZIPOutputStream to compress the stream .
I found the difference between C# and Java Gzip compression while a compressing a file (temp.gif ) -
After Compression of temp.gif file in C# - compressed file size increased
while in java i found a 2% percentage of compression of data.
Could you please tell me , can i achieve same output in Java as compared to C# using GZIPOutputStream ?
Thank a lot in advance.

Does java provides a better compression than C#?no idea, i don't do c# programming. and, your question is most likely really: "does java default to a higher compression level than c#".
Btw what is faster compression vs. better compression?meaning, does the code spend more time/effort trying to compress the data (slower but better compression) or less time/effort trying to compress the data (faster but worse compression). most compression algorithms allow you to control this tradeoff depending on whether you care more about cpu time or disk/memory space.

What is the diffrence between package javax.sql and java.sql

Is javax designed for J2EE?
And when to use package javax?

Hi,
What is the diffrence between package javax.sql and java.sql?The JDBC 2.0 & above API is comprised of two packages:
1.The java.sql package and
2.The javax.sql package.
java.sql provides features mostly related to client
side database functionalities where as the javax.sql
package, which adds server-side capabilities.
You automatically get both packages when you download the JavaTM 2 Platform, Standard Edition, Version 1.4 (J2SETM) or the JavaTM 2, Platform Enterprise Edition, Version 1.3 (J2EETM).
For further information on this please visit our website at http://java.sun.com/j2se/1.3/docs/guide/jdbc/index.html
Hope this helps.
Good Luck.

What is the diffrence between My Runnable Interface and Java Runnable

Hi folks
all we know that interfaces in java just a decleration for methods and variables.
so my Question is why when i create an interface its name is "Runnable" and i declared a method called "run" inside it.then when i implements this interface with any class don't do the thread operation but when i implement the java.lang.Runnable the thread is going fine.
so what is the diffrence between My Runnable Interface and Java Runnable?
thnx

Hi folks

so my Question is why when i create an interface its
name is "Runnable" and i declared a method called

with any class don't do the thread operation but when
i implement the java.lang.Runnable the thread is going
fine.
so what is the diffrence between My Runnable Interface
and Java Runnable?
thnxClasses and interfaces are not identified by just their "name", like Runnable. The actual "name" the compiler uses is java.lang.Runnable. So even if you duplicate the Runnable interface in your own package, it's not the same as far as the compiler is concerned, because it's in a different package.
Try importing both java.util.* and java.awt.* (which both have a class or interface named List), and then try to compile List myList = new ArrayList();

Java SE and Java EE

I am a IT graduate and I still need some clarification on the relationship between Java SE and Java EE API. Does EE include SE?
For application development, I know I can use only SE without the EE, but can I use EE alone without SE?
Any good articles addressing my questions?
Thank you very much
R

Java EE in fact extends java SE, its primarily aim is to simplify developing multitier enterprise applications (Java SE provides all the necessary basic libraries etc.)
Because Java EE is an extension of Java SE, you cant use EE without SE - without SE there is no EE.

SSO between Portal and Java WD application

Hi Experts,
I am using CE 7.2 on localhost and I am very new to SAP.
I need to know how can I get SSO between Portal and Java WD. I have a WD application that displays the logged in user using "IUser currentUser = WDClientUser.getCurrentUser().getSAPUser()", as well I can use "IUser user = UMFactory.getAuthenticator().getLoggedInUser()". Both work.
Q1. What is the difference in the 2 above?
Q2. My WD application is set to authenticate user. The WD application is in URL iView. I need SSO between Portal and WD application. Is there a way to get this SSO without SAP Backend (ECC), for now I just need SSO between Portal and Java WD appl.
Everything is in localhost.
Please advice. Thanks.

> need to know how can I get SSO between Portal and Java WD.
Then I suggest you ask your question in the Web Dynpro Java forum instead of the Web Dynpro ABAP one.

J2me and java card, need help to communicate

we are trying to put together a reader to read smartcards using j2me and we figure that it would be easiest if we could develop it to work with java cards rather than standard smart cards, the problem is we get garbage when we communicate to it, the chip sends us crap, any suggestions what might be wrong, any calls we might be missing, has anyone worked with j2me and java cards or smart cards, any help would be appreciated.
einar

.... reader app and the ME behind it .... smells like mobile ....
First of all - if you want to have one mobile application running on this just make sure that whatever is written in ME can use drivers from the reader chip ....
Workin on the PC is something completely different. There was one good example how to develop one host application in Java provided with the JCOP tools long ago ... I don't know if this is now in the new Eclipse tools.
But - there was a small API provided that can give you good hints what to do - and - once you have it on the reader side - you can easily integrate ME methods with this ...

Problem with win2000sp3 and Java web start

I have JRE and Java web start (1.2.0_01, build b01) which come downloading file j2re-1_4_1_01-windows-i586-i.exe from sun.
I have win2000pro running on my PC.
I had updated win2000 to service pack 2 and everything was fine.
Now i decided to update to service pack 3 (in the process I also updated other components) from Microsoft and:
1) Java applets seem to be running fine within i.e.
2) If i try to run an application from java web start my PC freezes and I have to restart it.
3) Staroffice 6.0, which runs on Java, seems to be fine.
I reinstalled both sp3 and jre etc, with no result.
Is this a known problem?
Thanks to all.
Maurizio

I suspect that you have hit a known problem with Swing on Java 1.4.1 with buggy video drivers. Do you have an ATI card? They are the worst offenders. ATI released new drivers for its Radeon line today. They fix the problem.

You need to elaborate "not working" in developer's perspective instead of in user's perspective.

Report Script returns no data and "java.io.FileNotFoundException" error

When attempting to write to a new file (Eg: C:\TEST.txt), Report Script returns no data and "java.io.FileNotFoundException" error occurs.
This error occurs only in Essbase 9.3.1.3 release, however it works fine in release 9.3.1.0.
After running the report the script, it pops up the follwing message:
"java.io.FileNotFoundException: ..\temp\eas17109.tmp (The system cannot find the file specified): C:\TEST.txt"
When checked the TEST.txt, it was empty.

Sorry folks, I just found out the reason. Its because there was no data in the combination what I was extracting.
but is this the right error message for that? It should have atleast create a blank file right?
