File size: 4.4 KB


  1. BASE 3.2 or later.


This package contains a few simple variants of Hello world applications in the form of extensions to the BASE web client. The package installs several examples into the Extensions -> Hello world examples menu:

  • Hello world! - A basic example using only javascript
  • Hello factory world! - An example that uses a custom action factory
  • Greetings Root! - An example of a custom action factory with parameters
  • Hello JSP world! - Uses a JSP file to display the message instead of javascript
  • Hello X-JSP world! - Another variant of a JSP file
  • Hello Servlet world! - Uses a servlet to generate the message
  • Hello Servlet world (alternate)! - Uses an alternative servlet path

There are also a few toolbar button extensions:

  • More info - A toolbar button on all single-item toolbars and displays some information in a popup window about the current item.
  • Annotation filter - A toolbar button on all list pages for annotatable items which allows a user to show only items with/without annotations.

And a edit/save extension:

  • Sample history data - Two extensions that works together. The first adds a tab to the "Edit sample" dialog were the user can select a file to link with the sample. The second extensions attaches to the save event and saves the link.
  • Last updated by - An on-save extension that creates an any-to-any link between any item and the currently logged in user. This is a very simple logging feature that stores information about the last update to an item.

And some extra list columns:

  • Owner registration date - Adds a list column that display the registration date of the owner of the item. The column is added to all list pages that list items that have an owner.
  • Onwer email - Adds a list column that display the email address of the owner of the item. This uses a custom formatter to create mailto links on the web page and a formatter that convert to upper case when exporting. The column is added to all list pages that list items that have an owner.
  • Data files - Adds a column to the raw bioassay list that display the data files that are attached to each raw bioassay. This uses a custom action factory and illustrates the possibility to create fullblown HTML for the web page, and a text-only variant for the table exporter.

This package contains the following plug-ins:

  • An importer that pretends to be able to import samples. It will accept any file, but doesn't do anything. Main purpose is to show parameter handling with plug-ins.
  • An analyser plug-in that does some bogus calculations on a bioassay set. Main purpose is to show how a plug-in can access analysed data, do some calculations and store the result as a new bioassay set.


  1. Download the base-examples-*.tar.gz file.
  2. Unpack the downloaded file to a directory of your choice.
  3. Copy the 'base-examples.jar' file to your BASE plug-ins directory as configured in the base.config[plugins.dir] setting.
  4. Go to 'Administrate->Plug-ins & Extensions->Overview' page.
  5. Run the installation wizard and select to install 'base-examples.jar'.
  6. The Hello X-JSP world example requires that the X-JSP compiler is installed on the server. Read in the documentation how to do this.
  7. Done. You may have to use 'BASE->Reload permissions' from the menu to see the 'Extensions' menu.


To compile this package you also need:

  1. Ant 1.8
  2. Java 1.6

Follow these instructions:

  1. Type ant download-lib to automatically download the BASE core JAR file that are neeed for compilation. You can also do this manually by copying the base-core-3.1.0.jar and base-webclient-3.1.0.jar files from the BASE installation directory (<basedir>/www/WEB-INF/lib/) to the ./lib/compile directory.
  1. Type 'ant' to compile the code and generate the 'base-examples.jar' file in the project directory. This file can be installed into BASE following the intructions above.
  1. Use 'ant package' to create a downloadable tar.gz.

  1. If you create a file called '' and enter a the path to the plug-ins directory under the key 'base.plugins', you can simply type 'ant install' to copy the examples to the BASE plug-ins directory.
