Is Java 5 SDK available as a .zip package?

Is Java 5 SDK available as a .zip package as opposed to a standard .exe download?
Thank you

I think you will not be able to download a JDK as zip for Windows. Java is not just installed in a folder under programs but also set registry entries, put some stuff in windows system folder, environment variables and so on. You can try to zip the Java installation folder and move to another Windows machine. But I guess I will not run properly.

How good is the java Ras Sdk in Business objects XI?

I have programmed some reports from scratch by using the java ras sdk.
Somehow I have the feeling that new features of XI like dynamic image location, or
running totals aren't so well supported as for example through the Crystal report Designer.
Do others also think that Business objects is being a bit negligent on this Api?
Maybe they do not consider the Api as important anymore because most people will be using there web based out of the box jsp components?

Normally you should run your CR reports in the INfoView. You can start a report either by double clicking on it or by selecting View in the context menu. Still in order to fetch data you have to press the Refresh button in the CR viewer window (in the InfoView).
In the CMC I assume that you are using the Run now option in the context menu. Please note that this will just schedule your report immediatelly. hen the report is scheduled a new instance is created hich is available in the History of the report. In order to see a report in the CMC select again View in the context menu and you can again fetch data by pressing the Refresh button.

Java ME SDK 3.0 OSX bug

Today I decided to migrate from Netbeans(windows) to Java ME SDK 3.0 (os x)
The project compiled as expected but when I start the game this is the exception I get:
java.io.IOException: error in native parseObjChunk proc.
On the phone the game works, on the WTK emulator (windows) it works as well.
The code that throws the error is:
Object3D[] allNodes=Loader.load("file.m3g");The m3g file is exported from Blender, if needed I can send it to you, just give me an email.

It is related to the configuration of the emulator (CLDC 1.0 or CLDC 1.1)...
If the configuration is CLDC 1.0 all the floating point data types (float, double, Float, Double) will not be available...
If you change the configuration to CLDC1.1 , then all the previous types will be available.
PS: I don't know how to do this in EclipseME

Java ME SDK 3.0 Math Class

Using Eclipse and Java ME SDK 3.0
When the Application Descriptor configuration is set to use DefaultCldcPhone1 or other emulators in the Java ME SDK 3.0 many of the Math class methods such as Math.sqrt(double arg0) are not available. However if I change the configuration to use a Nokia emulator all the Math class methods become available.
This issue has just shown up since moving from WTK25 to Java ME SDK 3.0
Note:
Under Eclipse/Preferences/Java ME/Device Management the Configuration of all the emulators from the Java ME SDK 3.0 is listed as CLDC-1.0 whereas the other emulators from Nokia and from the Sun Java Wireless Toolkit 2.5 are listed as CLDC-1.1.

It is related to the configuration of the emulator (CLDC 1.0 or CLDC 1.1)...
If the configuration is CLDC 1.0 all the floating point data types (float, double, Float, Double) will not be available...
If you change the configuration to CLDC1.1 , then all the previous types will be available.

How to deocde a Base64 String in Sun Java ME SDK 3.0(Urgent)

Hi there, I want to decode a base64 encoded String in Sun Java ME SDK 3.0 , but cant find any solution to this, after doing search related to this I found that it's very easy to decode a Base64 string in Sun Wireless Toolkit 2.5 using following code:
import com.sun.midp.io.Base64;
byte[] data = Base64.decode(EncodedString);
But I found that it's not possible in Java ME SDK as com.sun.midp.io.Base64 is not available there, anyone please give me some alternative of above code so that I can decode a Base64 String in Java ME SDK.
Eagerly waiting for the possible solution.

Can you please let us know as how you solved the problem? Since we are developing a blackberry app, we found base64 class for blackberry development. We have plans of doing the same in android, not sure whether they have this. As long as we have generic base64 class that can be used in any client device, that would be great. I did a lot of research and could not fine. Please give us the solution.

Java ME SDk Tools plugins error

Yesterday I couldn't find Device Selector window in Eclipse. And when I realized that the option of Java ME was dissapeared in "Tools" I went to take a look to the plugins.
I unistalled both Java ME SDK tools and Java ME SDK Demos. In order to instal them again. But I get the message below in the pugins window:

I followed all the steps last week to get the same developing environment but I don't know what has happened.
Any help will be very usefull. Thanks

I had a similar issue after uninstalling the early release of the SDK. I think it unloads some core components from the IDE. I don't remember the exact steps to fix it, but it was something like this:
1. Under Plugins dialog box, Settings tab, check the "NetBeans Distribution" option.
2. Once the window refreshes, look under Available Plugins
3. You should see a Java ME option. Install that.
After I installed that I went back and followed the steps to install the SDK. Not sure why it worked, but it did.

JAVA ME SDK 3.2

Hi,
I need Java ME SDK 3.2 for a project. I don't see on the downloads page, where can I still get it?
Thanks.
Guy

Hi,
Sorry for the late answer.
Java ME SDK 3.2 is needed to build Eclipse PAHO MQTT library (org.eclipse.paho.mqtt.java.git - MQTT Client Package - Java Language).
From the README file:
Paho Java ME client for MQTT
The Java ME client requires the Oracle J2ME SDK 3.2 (which is only available for windows) and assumes it will be installed in c:/Java_ME_platform_SDK_3.2/
The client jar is built using ant and the build.xml file in org.eclipse.paho.jmeclient.mqttv3/

Why do not have a "Java ME SDK 3.0" for the Linux environment, yet

Some developers need this tool. Will be available soon?

This thread is duplicated
I tried this solution Errors when starting Java ME SDK 3 - Windows 7 x64 and it worked with me.

Java me sdk tool 3.0's emulator isnt working

I'm using JAVA ME SDK TOOL 3.0
I don't know why this is happeneing but id really appreciate it if someone could tell me why it's happening. Im finished with the app i was working on and decided to take a break. I come back and its not working. The emulator wont start as you can see. It just so happened that i had to format my pc so i did and after installing everything again it worked. Yes i did consider reinsatalling the tool alongside jdk but it didnt work. A week later, today, i come back to check up on the tool and this is what i get.
What now? Why won't it work? :(

Java 2 SDK compilator for beginners

Hi to all here.
I am really sorry to disturb you all,
I am beginner in Java and I need to download Java 2 SDK compilator in order to compile my homeworks. I went lost in all the reliese EE, SE and so on I saw in Sun homepage.
Which one is the right one ?
I have Windows Vista Home edition in my computer.
Thanks for helping me.
Flavio

Download and install a Java SE 6 JDK for your Windows platform which is available here:
http://java.sun.com/javase/downloads/index.jsp
If you want some GUI Application you may choose the version containing NetBeans, if you only want the compiler and runtime environment install the first option (JDK 6 Update 4).

Java ME SDK 8 Plugins for Eclipse?

When will an Oracle Java ME SDK 8 (Early Access 2, )Plugins for Eclipse become available?
Thanks.

We plan to have Eclipse support around June/July, in accordance with the original Eclipse schedule for Java 8 support - this is because ME SDK 8 also needs the updated Eclipse MTJ framework.
Best,

Differences on Windows and Linux JVM about java.util.zip package

Hello, there!
I need some help if someone else has already face this problem.
I have a Java server that process the bytes of a SWF File stored in the server and ouptut it to the user through a Servlet. The file was decompressed and re-compressed using the java.util.zip package (Deflater/Inflater).
Everything works fine on Windows Server 2008 server. But now we need to migrate the server to Linux. The problem is that when I test the website now, the file seens to be corrupted.
What really intrigues me is that everything runs normal on Windows Server configuration, when changed to Linux, the final file seens to be corrupeted... what could possible be the cause? Is there any difference between java.util.zip package on Window and Linux JVM?
My Windows Server is:
. Windows Server 2008 (6.0 - x86)
. Apache 2.2.11
. Tomcat 6.0.16.0
. Java JDK 1.6.0_12-b04
My CentOS Server is
. CentOS 5.4 (2.6.18-164.15.1.el5 - i386)
. Apache 2.2.3
. Tomcat 6.0.16.0
. Java JDK 1.6.0_12-b04
Please, if someone could give me a lead, I would appreciate very much!
Thank you all in advance,
CaioToOn!

Thank you for the answer, but no. The path is correct.That's not what he meant. Zip file/directory entries are supposed to use / as the path separator. It is possible to use \ but such Zip files will only work under Windows. You may have erred here.Ohhh, I had really missunderstood what Ray said. But, I still think that this is not the problem, since the ZIP is a single SWF file generated by Flex SDK 3.4 and compressed in the ZLIB open standard (as in page 13, at [http://www.adobe.com/devnet/swf/pdf/swf_file_format_spec_v9.pdf|http://www.adobe.com/devnet/swf/pdf/swf_file_format_spec_v9.pdf] ). This is how Flash Compiler compress the files.
jschell wrote:
If the above suggestions do not solve the problem...Specify in detail with the exact steps used how you determined that it was corrupted.The reason why I believe the SWF is getting corrupted is that when it is loaded by Flash Player (in the client-side) the Player throws a VerifyError: Error # 1033. The [documentation says (see error 1033)|http://help.adobe.com/en_US/AS3LCR/Flash_10.0/runtimeErrors.html] that this error means that the SWF file is corrupted.
As I said, what intrigues me is that this work perfectly in a Windows Server 2008 server. I just had setup a CentOS server and deployed the application. The client-remains unchanged, so why could the result change?
raychen wrote:
I would remove the side effect you are doing and send the file straight through, with decompress and compress, the servlet. It is more likely that you have a bug in your swf processor than the zip library.
I had already tried it when first coding, in Windows Server 2008, it had not worked.
Thank you all for the help.

Java 5 SDK

Restate question:
If I decide to program and compile using the Java 5 SDK, will an end user with a 1.4 or lower JRE be able to view my applets?
And what if I decide to continue programming 'old style' and not to use constructs like generic types, whilst still compiling with the SDK5?
What it boils down to:
- Are all the SDK5 classes rewritten in SDK5 language?
- Do they all need a client JRE5?
- Or only the new classes?
Francis

I know the BigDecimal very well, but the old methods
BigDecimal.multiply()
are still there, the question is: does the compiled
source code need a JRE/JVE that uses Java5 or can it
run on a Java 1.4 or 1.3?That isn't the problem. Take a look at the constructors.
public BigDecimal(int val) (since 1.5)
public BigDecimal(double val) (older constructor).
So e.g.
new BigDecimal(3)
compiled with JDK 1.5, but with 1.4 compability will still not execute on 1.4 since the constructor:
public BigDecimal(int val) isn't available in JDK 1.4. The same code will however compile under 1.4 (and use the constructor with the double argument). The code will also execute on JDK 1.4, if it is compiled with the libraries from JDK 1.4.

Focus issue with CardLayout (Java 2 SDK, Standard Edition 1.4.0_01)

I am having an issue with focus and CardLayout with Java 2 SDK, Standard Edition 1.4.0_01. I have created a small sample application to illustrate my problem. In general, I am trying to create a "Wizard" that the user will enter information and then press a "Next" button to proceed to the next step.
When the first card is displayed, the focus is on the first text field as expected.
When I go to the next card by clicking "Next", the focus is not on the text field that has requested it (through the requestFocusInWindow method). The focus is on the "Cancel" button, which is the next component to receive focus after the "Next" button on that panel. I do notice that if I use my mouse to bring focus to the window the text field will gain focus.
Similarly, when I proceed to the last card, the focus is not on the "Finish" button until the mouse moves over the window.
Is there something I am doing wrong or is there a bug with focus and CardLayout?
One other problem I have noticed is that the buttons no longer respond to the "Enter" key press and instead respond to the space bar. Any suggestions as to why this is the case?
Thanks,
S.L.

Manfred,
Thanks for your reply. I tried requestFocus() and it gives the same results. Also Sun's 1.4.0 API (http://java.sun.com/j2se/1.4/docs/api/) mentions the following with respect to the requestFocus() method in the JComponent class:
Because the focus behavior of this method is platform-dependent, developers are strongly encouraged to use requestFocusInWindow when possible.
That is why I used requestFocusInWindow.

Oracle Berkeley DB Java Edition High Availability (White Paper)

Hi all,
I've just read Oracle Berkeley DB Java Edition High Availability White Paper
http://www.oracle.com/technetwork/database/berkeleydb/berkeleydb-je-ha-whitepaper-132079.pdf
In section "Time Consistency Policy" (Page 18) it is written:
"Setting a lag period that is too small, given the load and available hardware resources, could result in
frequent timeout exceptions and reduce a replica's availability for read operations. It could also increase
the latency associated with read requests, as the replica makes the read transaction wait so that it can
catch up in the replication stream."
Can you tell me why those read operations will not be taken by the master ?
Why will we have frequent timeout ?
Why should read transaction wait instead of being redirect to the master ?
Why should it reduce replica's availability for read operations ?
Thanks

Please post this question on the Berkeley DB Java Edition (BDB JE) forum Berkeley DB Java Edition. This is the Berkeley DB Core (BDB) forum.
Thanks,
Andrei
