How to install Eclipse in a USB Flash drive? I tried installing it on my flash drive and it is working fine in home computer, from which I installed. But when I inserted my USB drive in my friend's computer, it is not running. It is showing some error. Am I missing something which is very obvious?
Is it possible to install JDK on a usb drive without depending on host computer's registry settings or class path settings?
How to make my java development environment work on my USB Drive? What are various alternatives?

Mallesham,
Welcome to JavaRanch!
Eclipse does not do anything to the registry, so there aren't any problems on that front. I've never run off a USB drive to help with the rest of the question though.

The only thing I can think of is that the drive ID may not be the same between the two computers, possibly causing some saved info to get lost.
Of course you do have to have a JDK and the JAVA_HOME environment variable set on each machine or it won't run.

Science is the process of replacing what we 'know' with what is TRUE. Politics, alas, often prefers to be the opposite.

If you'd tell us what *specific* error you get, that could be of great help.

Running java from an usb-stick on windows should be possible, if you set PATH and JAVA_HOME:
---java_env.bat---
set USB_DRIVE=F:
set JAVA_HOME=%USB_DRIVE%java1.5
set PATH=%JAVA_HOME%jrebin;%PATH%
cmd /x
-------eof--------
should be sufficient.
I guess you realized, that the drive-identifier 'F' may vary from machine to machine and circumstances (other attached usb- or external drives).
This should work, but of course usbsticks are of low performance, compared to harddrives, so I guess it will not be much fun, to run javac and java that way.
My usb-stick conforms only to usb-1 - perhaps an usb-2.0 situation is better. Whether it's sufficient is up to your tests.
I start eclipse with the full path:

and would use

when trying to start it from my stick.
In eclipse itself you have to specify the jdk-location (compiler, java) again, and I don't know, whether a system-variable (%USB_DRIVE%) will work here, but I would give it a try.

Thanks Stefen for your help. I will try to do as you suggested and let you know the results in the next post.

To Tim and Stefan Wagner,
I don't believe Eclipse uses the JAVA_HOME environment variable to find the Runtime JVM on either Windows 2000 nor Mac OS X.
I've spent a lot of time trying to persuade Eclipse 3.0.2 to use JAVA_HOME on Mac OS X 10.4.1 (Tiger), and I have just verified that it does not use JAVA_HOME on Windows 2000 machine. In both cases, Eclipse is simply using whatever version of Java is served up by the OS.

Or whatever you tell it to use by the -vm argument...

True. I posted something similar in the Mac OS forum. I'll post an update there too.

Usb Video Adapter To Tv


Given the ease of use of the (double) click metaphore, I find that Windows provides a simpler solution that the Mac. I can add the -vm argument to the Properties of an Eclipse shortcut in Windows, but I have to launch from a command-line in Mac if I want to add any -vm arguments.
There may be another way on the Mac, but I don't know it yet.

Note: Do not physically connect the USB video adapter to your computer until instructed to (Step 7).

  1. Download the latest drivers from the StarTech.com website (http://www.startech.com/Support). You can find the part number and product ID on the product’s packaging.

Note: Mac OS X will typically save the files to the Downloads folder that is associated with your user account (for example, hard_drive_nameUsersyour_nameDownloads).

  1. Double-click the DisplayLink.zip file.
  2. Double-click the MAC OS folder.
  3. Double-click the appropriate folder for your operating system.
  4. Double-click the DisplayLink Installer 75598.dmg file.
  5. Follow the prompts to install the new drivers. Restart the computer when prompted.
  6. Once Mac OS X has restarted, connect the USB video adapter to your computer.

Note: Installation might take several seconds to complete. During the installation your display might flicker; this is normal. Once the installation has completed you will see your Macintosh desktop extended to the additional monitor.
