JSesh Download

download now !

download Windows version now !

Old versions of JSesh, as well as JSesh sources, can be downloaded from SourceForge. You can also subscribe to the JSesh mailing list (which is very quiet right now).

Note to web site authors: if you want to give a link to allow the downloading of JSesh, please use http://jsesh.qenherkhopeshef.org/download instead of a direct link to the software itself. The reasons :

  1. It will give a pointer to the JSesh web site and its information ;
  2. more important, even if you don't change your page, your users will always be directed to the latest JSesh version. I don't feel like maintaining all versions of JSesh at once.

Installation instruction for mac

JSesh has been tested on Mac OS X 10.3 (panther), 10.4 (Tiger) and 10.5 (Leopard). It might work with Mac OS 10.2 (jaguar) if you upgrade the software called "java" to version 1.4.1 (see here) However, I haven't tested it.

Download JSesh-install_....jar. It's an installer. Start it (double click), and follow the instructions.

The installation creates a directory containing the documentation and a Mac Application. Go to Application/JSesh to lauch JSesh (click on the owl hieroglyph).

I had recently some problems, installing JSesh, as the mac told me I didn't have the right to write in "/Application". Now, this can be fixed in two ways: open the mac "disk utilities", and select "fix permissions". It will normally give you the right to create files in "Application". Now, while this is the mac default setting, from a security point of view, forbidding write access to "Application" is a rather sane point of view. So, another solution is to install JSesh in a folder where you can write. Then, if you want, you can move it to "Application" (It would be possible for me to create an installer which is executed in "administrator mode", but I think this should not be necessary for a "user" application).

Installation instruction for windows

First, be sure to have a Java Runtime Engine (JRE) (a program which can run java softwares) on your computer. You can download one for free at http://www.java.com.

JSesh should work with java 1.4, 1.5 and 1.6.

Install your JRE

Download JSesh-install_xxxx.exe. It's an installer. Start it by double-clicking on it.

Follow the instructions.

Now, JSesh is installed ; a desktop shortcut is created. Just double-click on it.

Installing JSesh on Windows seven (64bits)

Some users have had trouble installing JSesh under the 64bit versions of Windows 7 (if you could install run-of-the-mill Windows 7, let me know). This problem will probably be resolved in the next version of JSesh.

Meanwhile, it is still possible to use the software.

  • Start the installation
  • It will block when creating shortcuts
  • Simply ignore the problem and quit the installation
  • JSesh is in fact installed, but no shortcut has been created to lauch it.
  • go to the folder
c:\Program Files\JSesh\libs

(well, in the folder where JSesh is installed, and in the "libs" sub-folder).

  • click on jsesh.jar
  • JSesh should start
  • In some installations of Windows, the software "thinks" that jsesh.jar is a zip file and opens it as such instead of launching the program. In this case, shift-right click and select "Open With / Choose Program" (see image below). You then select "Java (™) Platform binary", by checking the box "Always use this program" to avoid having to perform the manipulation in the future.

Other possible problems with windows

  • you may find that windows opens the JSesh-install program as a ZIP file. That's because Winzip (or some similar program) has "stolen" the treatment of jar files from java. The windows specific install file should solve the problem. Alternatively, the solution is not too complicated: right-click (or shift-right-click) on the JSesh-install file, you will get a menu. Select "open with..." in this menu, and choose Java. It should start the installer.
  • I found that it was difficult to install java itself on some versions of windows and on some computers, and at some time I had problems installing some java softwares, like netbeans. In those cases, a possible solution is to turn off the graphical optimisations of windows (usually just during the install process. To do this, right click, select property, go to parameters, and click on "advance". There should be a tab on problems solving (in my french version of windows it's called "dépannage". Select "no optimization". It's done. Note that I did never need to do this for JSesh itself: you can revert to your usual level of graphical optimizations after installing Jsesh.
