    Default How to start Dr Java (SOLVED)

    Hi folks,

    Win 7 64 bit
    Dr Java

    I have Dr Java download and installed direct on DrJava. It works after installation completed. But after reboot I can't start it.

    What happen? Did you get any error message? Check on the event log you could find more details about it, and also check on the process list for existing instance.

    Hi,

    I can't find its execute.

    On \Local Disk\Program Files\
    no Dr Java folder found

    On \Local Disk\Users\UserA\drjava

    It is only a file.

    Right click -> Open
    Windows can't open this file. It is NOT an execute file.

    Do you have an installation or the stand alone execution? Is that listed in your program list, or the add remove program list?

    On
    DrJava
    Old Stable Release

    There are 2 tabs relevant
    - Download Jar File
    - Download Windows App

    I clicked the 2nd tab "Download Windows App"

    It download "drjava-stable-20040326.exe
    -> Run

    I suspect whether the software has been installed? Whether I should click the 1st tab "Download Jar File" or otherwise?

    Thanks


    Edit:
    ===

    tools.jar is in C:\Program Files\Java\jdk1.6.0_20\lib

    But I can't start it.

    the backgroud of drjava is quite interesting. some lines from the abstract

    DrJava is a pedagogic programming environment for
    Java that enables students to focus on designing programs, rather than learning how to use the environment ... DrJava supports a transprante programming interface designed to minimize the "intimidation factor" that beginning students expericence when confronted with the task of writing code

    high pretense, but imho legitimate, but achievable?

    Hi j2me64,

    Thanks for your advice which works for me.

    I suppose previously I only ran the program online without download it on Win 7.


    Performed following steps;

    Start Win 7 and login as satimis. Download drjava-beta-20100507-r5246.jar on C:\Users\satimis\DrJava

    Start "Command Prompt"
    >C:\Windows\System32\javaw.exe -jar \Users\satimis\DrJava\drjava-beta-20100507-r5246.jar

    Drjava starts


    How to create a shortcut/program on satimis' desktop to start Drjava without executing it on Command Prompt window each time?

    TIA


    B.R.
