I have put a mysql.jar (a jdbc driver) as a pluging project library. Using
the classes from the jar is not a problem when running the plugin. The
problem is when loading the driver using:

Class.forName("com.jdbc.mysql.Driver") ,
it throws an ClassNotFoundException. I figure that it's something with the
class loader that the platform uses for plugin projects. Any idea how to
solve this?

Thanx

Where is the class that executes the forName stmt defined? If it is not
in a plugin that has the com.jdbc.mysql plugin as a required plugin, it
won't find the code in that plugin. Each plugin only has its required
plugins (recursive to the root) visible. Other plugins are not visible
to it.

Rich:

This is where I am hung up. I created two plugins by wizard,
SQLEditCommander and SQLConsole. I am making a TOAD type toolset for doing
SQL work in my Java projects in Eclipse. I have done this with Swing as a
standalone app. Anyhow, I am confused as to how I do the packages and how I
do the directories when I use the wizards. It looks like now, to write to
the Text object in the SQLConsole view, I will establish or mimic the
listener code in the plugin-architecture doc below.

How do I setup the plugins as far as directories? Do I need to create the
console, the listener Interface, etc. deeper than the Editor? And, do I
create the .exsd file in a schema directory under the editor directory?
And, is my editor (holds the menu actions) where the extension point is
defined, and the console is where the extension is defined?

Thanks,

David

I'm sorry but I don't know anything about SQL or what TOAD is. And I
don't understand the architecture of what you are trying to do.

The basic thing to remember with plugins is that they have an isolated
view of the world with to respect to classes. They can only see classes
that are in their own plugin or any plugin they pre-req (and so on down
to the route).

I don't know what you mean by structuring directories and EXSD schemas
and so on. :-(

You want to say that I need to create a new empty plugin just to be a
container for the mysqlc.jar ( the jar that contains com.mysql.jdbc.Driver
class) ?

Basically, yes. All jars that plugins reference must be in a <library>
element in some plugin.xml that that that plugin has AS a <required>
plugin. Your mysqlc.jar could be in the same plugin as your other jars,
but it must be listed as a <library> for that plugin.

Look at:

http://www.eclipse.org/articles/Article-Plug-in-architecture /plugin_architecture.html

to understand how plugins work.
