  3. Actually you dont need a restart... you can simply do a source to reload the changes.

  4. @Rajat Thanks,
    so you have to just type

    source /etc/bash.bashrc

    to reload the changes.

  5. Hi Suho Thayan

    I try to get Ant working in Ubuntu 10.04.

    I need this because I want to try to install Opentaps; kind of ERP for lean manufacturing

    As I followed your instructions. Not succeeded, Build XML does not exist.

    I also tried all the files in /usr/lib/jvm:
    - java-1.5.0-gcj-4.4
    - java-1.6.0-openjdk In this one tools.jar was expected to be inside
    - java-6-openjdk
    - java-6-sun
    - java-6-sun-1.6.0.22

    I really hope you can help me out of this.

    Ant appears to be quite complex sometimes.

    Await your feedback with interest.

    Kind regards.

    Its nothing to do with Java, since it says Build XML not exist, ant should have got installed properly

    type,

    ant -version

    in your terminal. If it prints something like this,
    "Apache Ant version 1.7.1 compiled on September 8 2010"

    your done with the ant installation
    else run,
    sudo apt-get install ant
    to install ant

    when running ant you should run the command "ant" from the directory where it contains the file build.xml
    I think you can find one in the Opentaps directories

    regards

  7. Dear Suho Thayan,

    Thanks.

    I got the result you mentioned.

    http://www.opentaps.org/forum/opentaps-general-discussions/general-discussions-english/step-step-instructions-ubuntu
    These are instructions for install opentaps.

    Now I see!!

    I had to do cd the directory opentaps
    Then type ant.
    Now I get the result:
    Build successfull
    1 minute 54 seconds.

    Only one question remains;
    java home: Which one I should use:
    - java-1.5.0-gcj-4.4
    - java-1.6.0-openjdk In this one tools.jar was expected to be inside
    - java-6-openjdk
    - java-6-sun
    - java-6-sun-1.6.0.22
    Or does not matter???
    Till now thanks a lot!!

  8. great :)
    Use either
    - java-6-sun-1.6.0.22
    or
    - java-1.6.0-openjdk

    Any sun or openjdk latest version would do

    Sorry, I don't have experience in ERP-systems :(
