Most of the samples which make use of tables in a database use JDataStore as the default SQL server. JDataStore is included with the Enterprise edition of JBuilder and is available separately for the JBuilder Professional edition.JBuilder includes many sample projects which demonstrate use of its rich component library as well as use of Java base classes. The samples below are grouped by area. A brief description of each is included. Click on the sample name to load the project file into an AppBrowser window.
JBuilder samples are listed under the following areas:
If you install JBuilder as 'root', but run JBuilder under your normal user account, you will not be able to run any of the samples directly from the JBuilder samples directory. Attempting to do so will result in a compile-time error, Error #: 914: unable to write to output directory. In order to run a sample project, you must have read/write access to all files and directories created or used by the sample.
A shell script named 'chmod_samples' is provided in the samples directory which enables the user who installed JBuilder to control access to the samples. It should be run from within the samples directory. For example:
% cd /usr/local/jbuilder/samples
% chmod_samples
Usage: chmod_samples [-verbose] full
to allow all users to compile, run, and modify sample files
or chmod_samples [-verbose] run
to allow all users to compile, run, but not modify sample files
or chmod_samples [-verbose] readonly
to allow all users to read but not run or modify sample files
Alternatively, if you were not the user who installed JBuilder and you only have read-only access to the JBuilder samples subdirectory, you can copy the samples into a directory in which you do have read/write access to run the samples. Because some samples require files (e.g., databases) in other subdirectories of the samples directory, it is recommended that you make your own copy of the entire samples tree, if possible. Samples which try to access files in other samples directories write a message indicating the directory in which they expect to find a file. The message includes the name of the class trying to locate the required file. If necessary, you can edit that class to point to another location, rebuild, and re-run the project.
A simple way to copy the entire samples tree is to use the cp -R command. For example, to copy the JBuilder samples tree (assumed to be in /usr/local/jbuilder/samples) to a 'mysamples' subdirectory of your home directory, do the following:
% mkdir $HOME/mysamples % cp -R /usr/local/jbuilder/samples/. $HOME/mysamples
Another way to do this which will show you files as they are copied (or if your version of 'cp' does not support the '-R' option) is:
% mkdir $HOME/mysamples % cd /usr/local/jbuilder/samples % find . -print | cpio -pdmv $HOME/mysamples
