Cabri Java Project CabriWeb application

With an aim of facilitating the creation of HTML files using the CabriJava applet, an application written in Java called CabriWeb is available. Before seeing how to use it under various systems, present its functionalities:

 

At launching of the application, a window is displayed and the user have to choose a CABRI file produced by the application CABRI geometry II or a HTML file by the menu "Open.." or by the menu keyboard shortcut <command>O or <ctrl> O. These files must reside beforehand on the local disc of the user or be downloaded from the Web site which you want to edit. In this last case, it is advised to place on its disc a copy of work of the site identical to the original. Thus the names and files will be the same ones locally and on the site and no illegal reference to a non-existent file should occur. For the same reasons, it is advised to use only alphanumeric characters in the file names or folders.

Frst, consider the case of working on a Cabri figure. If the figure is well recognized like a CABRI II figure, the CABRI figure opens through CabriWeb and is handled like the applet, with in addition the possibilities of displacement and redimensioning.

Two menus are proposed:

• Edit makes it possible to choose the parameters to be used which will be deferred in page HTML backed up once. The colors suggested are the 216 colors known as of the Web (palette color of Netscape adopted by the other navigators). The basic images must be with format GIF (gif suffix) or JPEG (jpg suffix). Ten languages are present at this time for CabriWeb and CabriJava applet; other ones are in translation process or implementation like Greek...)

• File makes it possible to change figure or to record HTML file with corresponding parameters according to the state of the figure in CabriWeb. Attention, this recording can be made only if the place of the CabriJava.jar archive to be referenced in HTML page is known. This is why a dialog of choice of this file is proposed before giving the name and place of HTML file to be created. This choice of the jar file, as all the other parameters of Edition menu can be saved in a file of preferences by the special item menu of File. With the next opening of a figure, the old parameters will be reused. Note that at the time of a backup HTML file, tag <APPLET...>... </APPLET> is copied in the clipboard at the same time as the creation of HTML file; this can be useful for a direct paste in HTML code of a web page. A menu named "Upload on the Web" allows after connection to internet the transfer of Web page, corresponding Cabri figure and perhaps background image on a shared Web site to encourage direct publishing of CabriJava figures on simple clic. After the transfer, the URL of the newly Web page is displayed and copied in the clipboard to allow its referencing. It is also suggested to place a link in the constructing CabriJava gallery at http://cabrijava.free.fr

In case of working on a prerecorded HTML file, CabriWeb detects one or several CabriJava applets in the choosen file. If many CabriJava applets are called a dialog allows to choose one for editing parameters applet. When recording HTML file, all the text preceding and forwarding the choosen applet tag <APPLET...>...</APPLET> is stored; only the edited CabriJava applet tag is updated with new parameters. Take notice of the possibilty of writing in HTML file a placeholder tag like these

<APPLET CODE=CabriJava> </APPLET> or <APPLET CODE=CabriJava.class> </APPLET>

When reading such an empty applet tag, an empty window opens for the placeholder; then you have first to choose a Cabri figure to animate with CabriJava, afterwards you can edit its parameters..

 

How to download this beta version of the CabriWeb application ?

 

Several cases (even if Java is multiplatforms...) :

• for MacOS: two CabriWeb applications are available according to the version of MRJ which you use (MRJ is the Java virtual machine of Apple) The "MRJ version" application included can tell to you which version of MRJ is installed on your MacOS.
  • if your version of MRJ is old (but higher or equal to 2.0), use this version (170 KB)
  • if you installed the last version of the MRJ (2.2 or afterwards) available here, you can use this second version (190 KB) which proposes drag & drop possibilities of a figure or an image and creates HTML files which have an icon (that of the navigator iCab who is advised with CabriJava: use less memory than the others)
• for Windows: while waiting for a solution to distribute executable Java applications (Sun still offers a product under development), the best solution for running java applications is to call the Microsoft Java Virtual Machine, installed with Internet Explorer. A more recent version if avalaible at this page. Download the jar archive CabriWeb.jar from here after this, and then you can test this experimental version through DOS window by typing the command:

jview /cp CabriWeb.jar CabriWeb

 

in the folder where this CabriWeb.jar archive was downloaded. You can also use the command file CabriWeb.bat containing the command line above placed in the same folder as CabriWeb.jar archive.A double clic on this command file will launch CabriWeb.

• for Linux: it is necessary beforehand to install the virtual machine Java of SUN JDK in version 1.2 or afterwards. This virtual machine is available to this page for Linux. Another implemenation can be better integrate in Linux : see at http://www.blackdown.com Download then the jar archive CabriWeb.jar from here, and can test this experimental version through Terminal window by typing the command:

java -cp CabriWeb.jar CabriWeb

 

in the folder where this CabriWeb.jar archive was downloaded.

 

To resume download :

• by the web (http) :
  http://www.cabri.net/cabrijava/CabriWebMac1.sea.hqx (~170 Kb) for MacOS with MRJ 2.0 or after
  http://www.cabri.net/cabrijava/CabriWebMac2.sea.hqx (~190 Kb) for MacOS with MRJ 2.2 or after
  http://www.cabri.net/cabrijava/CabriWeb.jar.zip (~140 Kb) for Windows or Linux
