How to run java on computer without java from flash drive

Im running a chess club at school and the school computers, you aren't allowed to install on the hard drive.
Is there a way to put an ide and the java folder containing the jre and jdk on a flashdrive and run the ide and run programs solely from the lfashdrive?

Yes. put the JDK (not the separate JRE) on the flash drive. The JDK contains a JRE.
Plug the flashdrive into a computer you control. If that computer already has the desired JDK installed, copy the JDK directory (all of it) to the flash drive. Otherwise, do an install of the JDK to the flash drive.
To run Java application programs use a command that provides the full path to the java.exe program, for instance (in Windows)
*<drive letter>:\<some directories>java <the name of your program>*
You could create a bat file to make this easier to type.
You can't run applets or anything else that depends on Registry entries.

What is required for my program to run on a computer without Java installed

I was just curious if any body knew how to make a Java program that will open and run on a double click without java being installed on that computer. I've seen people mention that we can create a shortcut (though I'm not sure how) so that the program will run on a double click. I've also seen a link to a program that creates .EXE files but I would like to avoid using that.
I have a small group of friends that I would like to share one of my programs with, but they are not Java programmers and I don't want to clutter up their Hard Drive with the Java JDK or SDK.

First, make sure you package your program in a JAR file, will make things easier...
Under the folder you have the SDK installed on your computer, should be a folder named JRE.
Make a copy of the JRE in a folder underneath where your JAR file resides, for instance...
You Jar File is:
C:\JavaProgs\MyProject\TheJar.jar
Then put:
C:\JavaProgs\MyProject\JRE\...
In the C:\JavaProgs\MyProject\ directory, make a Batch file. Batch files are text document scripts that run windows commands. Just use a plain text editor and create a file called RunTheJar.bat.
The batch file should consist of exactly 1 line:
start .\JRE\bin\javaw.exe -jar TheJar.jarThen the users can just double-click the batch file to run your program...

How do I transfer files to my mac from flash drives

I'm trying to transfer pictures to my macbook pro from an SD card. Not sure how. Please help

Either your MBP needs to have an SD slot reader built-in or you need to purchase one that connects to the computer via USB port.

How to run a remote application (Non Java) from a Java program

Could you please tell me how to run a remote application (Non-Java) from a Java program without using RMI. Please tell me know the procedure and classes to be used.
Cheers
Ram

what do you mean remote application.In the other pc or in your pc just apart from you application?
If the application is in your pc,the method which the upper has mentioned is
a good one!
But if the application you want to run is not in your computer,the method can't do. And you can use socket with which you can build an application listening some port in the pc which contains the application you want to run .When you want to run that application ,send the Start_Command to the listening application.Then listening application will run the application with the help of the method the upper mentioned.

        catch (IOException ex) {
            System.out.println(ex.getMessage());
        }I've debug and see, but the exitValue is even not exist at run time. Can you tell me where I'm going wrong.

How can I change my computer's language from English to Spanish?

How can I change my computer's language from English to Spanish? My computer is an iMac G3 (CRT) and it has Mac OS 9 installed.

This isn't possible in Mac OS 9.2.2 and earlier without doing a full installation of the Spanish version of the OS, which requires an installation disk containing it.

Hi,
In order to resolve the problem more efficiently, I need to clarify some information.
1. Do you have two AD sites in your environment?
2. If you have two AD site, do you have active users in these two AD sites?
3. Does each AD site have a DAG which is cross-site?

If you have the Media you can use it to create a bootable USB key via boot camp assistant.
It will create the usb and has the option of pre-downlading the drivers and bootcamp utilities for windows.
It is pretty much all automated and quite simple.

How do I restore iTunes library from flash drive backup?

How do I restore iTunes library from flash drive backup?

How do I restore iTunes library from flash drive backup?
HI Brigdool,
It depends how you made the backup.
If you copied your entire iTunes folder onto the flash drive, just copy it back to the appropriate place on the computer.
If you copied individual folders or files, add them back to iTunes by inserting the flash drive in your computer, and then dragging the files into your "Automatically Add to iTunes" folder.
The first method recreates your library as it was, with all playcounts, playlists, etc. The second method builds a new library with the same content.

My usb confirmed bootable! I created it with bootcamp, and tested it on a different macbook and it works. But doesn't work on MacBook Air. (Even startup disk doesn't detect it as bootable in Air)
anyone else has a real solution to this problem?
Thousands have successfully tried it themselves and installed Windows on a Macbook Air. Perhaps if you provided some details about what you did and what errors you observed we could help you. The Boot Camp instaructions, if followed, will produce a successful install.

How to run BW reports since BI JAVA is not available in 7.4.

We have Upgrade our BW 7.0 to BW 7.4 on HANA, How to run our BW reports since BI JAVA is not available in 7.4.
My scenario: Producer Portal (BW portal ) we are creating/marinating Portal objects ( Folders, roles, work sets ……etc.), which replicate in Consumer portal (EP portal) via Federation framework. In-fact its abstraction layer, not hosting any Portal content physically but giving a unified enterprise access to business. The actual content and execution of users requests occur on Producer portal itself.
We have to maintain two portal in this case (consumer & producer).
In BW 7.4 version, dual stock is no longer supported. In order to maintain the federation paradigm have to purchase new license & servers for java stack. What about if we directly integrate our BW reports in EP portal ? what would be draw back or issues in this approach in terms of durability, maintenance administration efforts……….etc . Please suggest us the best design solution for me. Need expert opinion.
Now it looks like extra layer (Standalone JAVA stack) to maintain & host? Agree or no?
Is federation still have worth or have some else new SAP concept. ?
Thx,
Jameel

Hi Nawab,

Of course, do additional users and activity also consume ressources of the EP 'machine'.
If you'll run in performance leak, is depending on the special situation. And of course the AS Java can be tuned/optimized for higher workload.
Maybe if you are on a virutualized environment, it's easily possible to increase the ressources of the machine/s - or its possible to add additional java-nodes on separate servers...
Lots of possibilities to increase the workload-power if needed...
From my personal opinion, I usually recommend a separate BI-Java instance - not shared with other funcitonality.

Not sure if I get you right.
There are two technical options to run a ABAP+JAVA Stack on one server.
In one SAP instance - then ABAP and java processes are controlled in one framework. --> This option is not possible any more under 7.4
in separate SAP instances - then the two SAP systems are running on same host but each has its on framework/instance running. It is similar to running on separte servers.
Licensing:
From an SAP view, there is no additional licensing cost for the separte Java Stack!
But for sure, if you set it up on a separate server you may have additional cost for OS licensing, VMware, etc. - depending on your infrastructure...
My recommend, if you plan to move with that stuff to HANA:
Assuming you have 2-system landscape - DEV and PRD.
Assuming you are in a virtual environment like vmware.
Currentently you have two servers - on each a DualStack BW incl. current database on it.
1. Set up four new machines with half sizing as you currently have.
2. Split the DualStack and run the two new Java stacks on the new servers.
3. Migrate your BW ABAP to HANA
Set up the ABAP Application servers for your BWonHANA on the other two new servers.
4. Kill/Recycle the two now free servers.

Stefan

How can i open "my computer" in java

How can i open ]my computer[b in java

Two options:
1) Execute
Runtime.getRuntime().exec("explorer.exe ::{20D04FE0-3AEA-1069-A2D8-08002B30309D}");2) Look at javax.swing.JFileChooser
The first option will do what you want, but it is specific to Windows only (I tested it on XP, I don't know if it'll work on other versions). The second is cross-platform, but won't give you the same view as a native explorer.

How can i make the .exe run on the computer without Labview?

.exe can't run on computer without Labview. Is there any way? Thank you.

You need to install the LabVIEW Runtime engine for your specific LabvIEW version.
In the project window you can create an installer that includes the Runtime Engine (RTE).

Use of java on computer without install

Is it possible to run an application from a removable flash drive that has a copy of the jre. I am running an application on computers that have had the install run from flash disks but can not run on machines where the installation hasn't been done.

Yep, I had to do the same hackery when I was in school. Just install the JDK on another machine and then copy it to your flashdrive. You'll probably have to do some manual setup to comfortably use it though, such as manually adding the bin directory to the system's PATH so you can easily run java and javac. Something like
set PATH=%PATH%;f:\java\bin
or whatever the path to Java on your flashdrive is.
Of course when you don't do a proper install you cannot run jar's by double clicking on them, you have no browser plugins and thus can't run applets or webstart things through a browser.
