RAP and JDBC [message #47220] Mon, 17 September 2007 13:50 Go to next message

Hi,

I wonder how i would best use JDBC together with RAP.
Should I implement the JDBC-Driver as a separate Bundle
which is shared among Users?
Or what would be the best practice for this?

Sincerely

Martin

Is assume that you just want to package the driver jar into a plug-in
and not actually implement one as a plug-in;)

> which is shared among Users?

For the driver itself it shouldn't make a difference when accessed by
multiple threads.

> Or what would be the best practice for this?

A best practice highly depends on the use-case. If used by only one
plug-in I would tend to package the driver with that plug-in.
In other scenarios this may not be the best approach.

Hi,
I tried to update my RAP Environment by copying the new M6-Jars into
my plugin folder, but regrettebly eclipse is crashing since then...

Then I copied the files one after another and it comes out that this is
the bad guy:

org.eclipse.rap.ui_1.0.0.20070817-1525.jar

perhaps I misunderstood the principles of updating eclipse-plugins, but
the rap-update-site only provides M1... so I do it manually.

Hi Johannes,

the target platform downloads provided since M4 are *not* meant to be
installed into your Eclipse installation for exactly the reason you just
experienced. Sorry for that:(
Please follow the procedure described on the downloads page:
http://www.eclipse.org/rap/downloads.php

Cheers,

Why I asked is, I have the JDBC-Driver in an external Plugin,
in my base plugin, I have defined an extension Point, so that I am able
to contribute JDBC Drivers on the fly.
This can be important because I must support a wide range of Databases.
So, I load the Driver , using "createExecutableExtension",
and I do get an INstance of JDBCDriver.
But I am not able to get a Connection, instead I get a "no suitable
Driver found"-SQL-Exception. If I try the same thing with the driver
in the Classpath of my Plugin, this works so fine.
Is there a classloading-issue I am not aware of?
Or what?s the problem here?

Ok, this architecture works, if I put a dependency on my base plugin, but
this is not what I wanted to do.
Why does the approach with "createExecutableExtension" not work?

finally it works, its not an issue for RAP, but rather as I supposed a
Classloading issue.

Thank you anyway

Greetings
