1.4.1 JRE Support

Hi,
Does Oracle Workflow support the 1.4.1 JRE (or plugging in any other JRE)?
I am hoping to be able to develop a workflow-based app using Java functions/activities but I would like to be able to use new classes/features in 1.4.1. I would also potentially like to reuse classes from other projects within my organization, which may be written to the 1.4.1 features.
Also, are there any significant downsides to using Java activities instead of PL/SQL?
Thank you.

Raja,
Thank you for your reply. Just to confirm, only the workflow engine embedded in iAS 904 supports 1.4.1 and the standalone version does not?
To clarify, there is not necessarily a middle tier app calling through to the engine, though that may be one aspect of the system. My concern with JDK support stems from the fact that we would like to use Java functions via the activity agent. The functions that we write may leverage existing Java library code, some of which may rely on 1.4.1 functionality. In this case, we would need the JRE that is used by the Java function activity agent to support 1.4.1.
From your response, it seems that the engine bundled with iAS 904 does support this but the standalone workflow engine may not.
Is this accurate and a correct understanding of your reply? Thank you.

JRE support for JIS2004 (aka JIS0213?)

Do any of the releases of the JRE support JIS2004? If not, are there any plans for such support. I am most interested in JDK1.5, but any version would be fine. Apparently this standard (otherwise known as JIS0213, I think), is important to Japanese users of Windows Vista. I couldn't find any useful information on the Sun site regarding this question, so I apologize if I missed some obvious source of information on this question.
Thank you.

So if my remote objects extend UnicastRemoteObject
and use the exportObject(this,x) to export themselves
to port xHold it. If you extend UnicastRemoteObject you don't have to call exportObject, it is called for you on construction.
, do they effectively bypass the registry,
since the ports used for each are known to both
sides, and the remote Stubs can be placed in reach of
both?No. You can think of the Registry as a bootstrap which gives you the initial stub. After you have one stub to your system it can return stubs for further objects itself. (Actually it is LocateRegistry.getRegistry() which is the true bootstrap, but leave that.) Classically:
public interface Login extends Remote
/** login, suppliying whatever credentials are required */
Session login(String userid, String password) throws RemoteException;
public interface Session extends Remote
// further application methods here
}so a client can only get access to your application via a successful login. Thereafter the client may have its own unique SessionImpl object to communicate with, which can hold state on behalf of the client. If you have no session state, the SessionImpl can be a singleton, with preferably a better name, maybe in your case Warehouse.

Does JRE supports 64 bit?

Which version of JDK and JRE supports 64bit?
In windows OS, using java whether it is possible to convert a 32 bit file into 64 bit file?

Does JRE supports Windows 64 bit? If yes whats the vesrion.

When will the JRE support Intel 64EMT/Windows

I have an Intel dual pentium 4 processor that claims to support 64EMT. I was thinking about loading Windows 2003 Server 64 bit edition with JAVA to test our JAVA product we sell. I found out though that for Windows the current JRE only supports the AMD64 processor. Does anyone know when they will have a JRE that support the Intel 64EMT architecture on the Windows platform?
Thanks,
John

http://java.sun.com/j2se/1.5.0/system-configurations.html says that Sun's JDK-1.5.0_02 (and later) supports Windows Server 2003 x64 Editions on both AMD64 and EMT64T in 64-bit mode, among other hardware and operating system platforms. There isn't a plug-in for the 64-bit browsers.

Why doesn't jre support some fonts?

Like Bright - it's a monospace font, I've installed this font, but I can't use it in jedit.
Why?

Frankly, applets are really Web 0.5+. Time to jump up a few versions
This is a case where a mobile app would work much better than a web app trying to be more than a stateless display.
There are professional trading (equity) apps out there that work on IOS devices (not too many, because unfortunately WallStree took a long detour through Dot Net gultch).
You might search "Reuters" or "Bloomberg" in the app store or try something else.

64-bit jre support

I have 32-bit native libraries for Java application compiled on HP-UX 11.11 PA-RISC.It works fine.
When I build same library in 64-bit mode on 64-bit HP-UX 11.11 machineand trying to use same libraries with java application (jdk 1.3.1).
I'm getting error:
"System.loadLibrary(smjavacalcapi) java.lang.UnsatisfiedLinkError"
with following message
specified file is not a shared library, or a format error was detected.
The format of the library is showing ok,as:
ELF-64 shared object file - PA-RISC 2.0 (LP64)
Is this issue with jdk version. I am using jdk 1.3.1.
Thanks & Regards
Devendra

I have no idea what the setting is for HP-UX 11.11, but for Sun's VM (1.4+) on Solaris it is -d32 to run the vm in 32bit mode and -d64 to run it in 64bit mode. I think that windows and linux it is a seperate download and install to run in 64bit mode. I believe your problem is you are either running the HP-UX vm in 32bit mode or you need to install the 64bit version.
I don't know if 1.3.1 has a 64 bit version or not.

Is SDK, and JRE supported on XP ?

Just wondering here about this cause I'm having a bit of trouble running the applet even when it compiles with no errors.
Thanks,
Michael

I am using J2SDK 1.4.1 on my Compaq XP Home system with no problems. However, there is some problem with some video drivers that XP systems use. Search the forums for more details.

JRE 20 support

We are going to be rolling out JRE 20 to all of our user desktops. Typically SAP supports JRE going forward but in the past we have encountered issues with some of the newer versions.
Anyone seen issues with JRE 20 and MII 11.5 or 12.1?

Hello,
I believe the question of JRE support is just not related to MII alone but its more of a combination of several other factors too like OS, browsers versions, OS service packs etc.
You can refer to this link for details on supported system configurations for Java
[Supported System Configurations|http://www.oracle.com/technetwork/java/javase/system-configurations-135212.html]
Hope this helps!!

Support for TLSv1.1

Hello,
Because "TLSv1.1" is listed as a SSLContext Algorithm (https://cis.med.ucalgary.ca/http/java.sun.com/javase/6/docs/technotes/guides/security/StandardNames.html#SSLContext)
i have been trying to specify it in my code as shown below:
SSLContext sc = SSLContext.getInstance("TLSv1.1");
sc.init(kmFact.getKeyManagers(), tmFact.getTrustManagers(), null);
But i get the following instead:
java.security.NoSuchAlgorithmException: TLSv1.1 SSLContext not available
at sun.security.jca.GetInstance.getInstance(Unknown Source)
at javax.net.ssl.SSLContext.getInstance(Unknown Source)
I am using JDK1.6.0_4. Does it support TLSv1.1? Or do I find another provider (if there is one)?
Thanks

I am sorry.... in fact i was reading the wrong doc.... here is the one from java6 spec
The JSSE API is capable of supporting SSL versions 2.0 and 3.0 and Transport Layer Security (TLS) 1.0. These security protocols encapsulate a normal bidirectional stream socket and the JSSE API adds transparent support for authentication, encryption, and integrity protection. The JSSE implementation shipped with Sun's JRE supports SSL 3.0 and TLS 1.0. It does not implement SSL 2.0.
Link
nevertheless TLS1.1 is not implemented by java1.6 as well....
thanks ejp... for the correction....

What classes are required in a JRE

I am supporting code that utilizes sun.security.provider.Sun but get ClassNotFoundException when I run with IBM's JRE which doesn't have this class. Should it? Or how can I code around this. It seems that when I debug in JBuilder X that the exception happens from the ClassLoader before my main function.

Don't use the non standard sun.* classes if you want cross JRE support.

Sun's JRE invoked by IE?

Now that XP isn't going to be shipped with Microsoft's VM, does Internet Explorer support Sun's JRE?
I'm currently running Windows XP and whenever I encounter a Java class file on a web page it prompts me to download and install Microsoft's Virtual Machine. I already have Sun's installed on my computer, is there anyway for IE to recognize it or are they just incompatible?
Furthermore, will new releases of either IE or Sun's JRE support each other?
Thanks...

I suppose it will not be impossible to install Sun's Java Plug-in in the Internet Explorer that will be included with Windows XP. Using the plug-in, you could run Java applets in IE anyway. So I don't think we will be completely lost with Windows XP.
Note that the current version of IE (version 5.5) still only supports Java 1.1. Using the plug-in, you can run Java 1.3 in IE.
Have a look at:
http://java.sun.com/products/plugin/index.html
By the way, the plug-in is included with the JDK, if you install the JDK on Windows, the plug-in is also installed (look for the icon in Control Panel!).

Why isn't there a JRE Multi-Language for LInux

I can find the Multi-Language JRE for Windows but not Linux. Doesn't JRE support I18N in Linux?

Not having downloaded any special version of JDK, it seems that my installation supports i18n just fine on Linux (for example: JOptionPane uses localized default answers, based on the locale).

JREs in the wild

Hi folks,
It seems very hard to find out the following basic information. If anyone can direct me to statistics or reports or sites on this, I'd be very grateful.
Simply, what JREs are out there still operating for Java applets?
Is there guidance for me as a developer on how far back toward 1.1 I should make my code compatible? What is the most common JRE - 1.5?
I've tried Nielson and others about this but they have no idea. Sun does not seem to have stats on this either - even the number of downloads for each JRE over the years.
Cheers,
Craig.

I believe all of the MS products prior to XP SP 2, have 1.1.8 -- MS's JRE. Many of the new computers do not have any JRE loaded, or will be shipping in that condition very soon. So it is going to be interesting to see what happens with Java and applets, there will not be any JRE you can develop for that will be guarenteed to be on a machine, the user will just have a dead box and will have to choose to load a jre when they figure out what is going on.
Even though I have JDK for 1.3, 1.4, and 1.5 on my box, I see it is using the MS JRE for the browser and is required for some of the applications we use here.
Essentially if you are making an applet and you want it to run seemlessly, then you're going to have to make it for the point MS's JRE supported Sun's standards.

Hana Server Supported Java

Hi Experts,
I need to upgrade the Java JRE version in my SAP HANA Server but I want to avoid any problem, I'm looking in SAP Hana guides, the Java version supported in a HANA Server, but neither in the PAM or Installation Guide for SAP HANA Server I can identify this information, Do you have any information about this JRE supported in HANA Server or if exists a Prerequisites for HANA Server.
Thank you for your answers.
best Regards.

Hi everybody,
I find this SAP Note 1944799 - SAP HANA Guidelines for SLES Operating System Installation where I support the Update of the Java Release.
Best regards.

Clicking mouse after closing JDialog sends event to last component (1.1.8)

There seems to be a bug in Java 1.1.8 that I'm looking for a workaround.
I have a JButton on a JFrame that brings up a modal JDialog when you click it. After closing the dialog, if you click on the JFrame without moving the mouse, it will click the button on the frame that was last clicked, even if the mouse is not over the button.
Steps to reproduce:
1. Use the mouse to click on the button on the frame to bring up the dialog.
2. Close the dialog with the mouse or keyboard and don't move the mouse at all. (Note that the mouse should be over the JFrame at this point, but not over the frame's button.)
3. Click the mouse again.
Result:
This causes the button on the frame to be clicked.
It seems as if the frame thinks that the mouse pointer is located where it was when the dialog came up.
Does anyone know how to prevent this from happening or a workaround?

We are using 1.1.8 because our product has to run on Mac OS 8.x - 9.x (and this is the latest JRE supported by these platforms).
When I say don't move the mouse, what I mean is when closing the dialog, if you don't move the mouse, it doesn't matter where the mouse pointer is, as long as it's over the frame. When you click it, the last button to get clicked will be clicked again. It's as if the frame thinks that the mouse hasn't moved since the dialog came up. This isn't a focus problem because if I set the focus on another control after opening the dialog (by calling requestFocus()), this problem still happens. I can also tab to another control after closing the dialog, but when clicking the mouse it still clicks the last button that was clicked. It's as if the frame needs to reset where the mouse position is when it becomes activated.
