Re: Tales from the Dark Side

Hi Ken,

You can get  the PostgreSQL plugin and the PostgreSQLPlugin.bundle at 
http://www.hexdreams.com/.

You should download them, open them with xcode and build them.
I think you will need to have the postgresql jdbc driver to biuld them. 
You can get it at http://jdbc.postgresql.org/download.html
Choice one and put it into /Library/WebObjects/Extensions

Once you builded both plugIns you will have into the build folder of 
PostgresqlPlugInBundle project the PostgresqlPlugIn.EOMplugin folder. 
Copy or move it to /Developer/EOMBundles
Into the build folder of  the PostgresqlPugIn project you will find the 
PostgresqlPlugIn.framework folder. Copy or move it to 
/Library/Frameworks
Once you did that you can create a new project.
At the "Choose EOAdaptors" step of the wizzard select 
JavaJDBCAdaptor.framework and at the "Chose Frameworks" click the "Add" 
button and select PostgresqlPlugIn.framework and continue with the 
wizard.

Now just create a database in postgresql and create a new modeler 
directing it to your data base:
Username: "Your Postgresql username"
Password: "Your Postgresql password"
URL: jdbc:postgresql:"YOUR_DATABASE_NAME"
Driver: org.postgresql.Driver     ******* I think this not strictly 
necessary.

And that's it.

Hope this helps
