Hi,

I have some additional plug-is created with normal plug-in development tools.

1: Do I have to do anything else then specify them as required plug-ins.

2: Where do I put these plug-ins so that during development my scout server can find them.

Regards Bertin

1. that is sufficient. You can specify them as required bundles or add import dependencies as you like.

2. when running the application in development mode you probably use a *.product configuration. (dev-test.product or similar). There you add the plugins as well in the Tab "Plugins" or "Dependencies" (in new eclipse).

3. when running in production eclipse supports either for strict or lazy config.
More detail is in the eclipse platform / runtime help.
strict: use a configuration/org.eclipse.equinox.simpleconfigurator/bundles.info specifying exactly which plugins to use.
lazy: add the org.eclipse.update.configurator bundle and you're done since that one just loads all in the /plugins folder.

Did that help?

Thanks,

one step further. It can find the bundles now, not the class inside. As far as I can see the class is in the bundle ().

My guess is you are writing your own jdbc connection (db support
bundle). If so following these steps:

1. create a plugin project lets say 'org.eclipse.scout.rt.jdbc.microsoft'.

2. create the folder 'org.eclipse.scout.rt.jdbc.microsoft/lib' put the
jdbc driver jar (lets say sqljdbc.jar) in there.

3. open 'org.eclipse.scout.rt.jdbc.microsoft/META-INF/MANIFEST.MF'.
Switch to the 'Runtime' tab and add the sqljdbc.jar to the 'Classpath' box.

4. open 'org.eclipse.scout.rt.jdbc.microsoft/META-INF/MANIFEST.MF'.
Switch to the 'Dependencies' tab and add 'org.eclipse.scout.rt.server'
to the 'Required Plug-ins' box.

5. open 'org.eclipse.scout.rt.jdbc.microsoft/META-INF/MANIFEST.MF'.
Switch to the 'MANIFEST.MF' tab and add the line:
'Eclipse-RegisterBuddy: org.eclipse.scout.rt.server' (without the ').

6. create a new class
'org.eclipse.scout.rt.jdbc.microsoft.AbstractMicrosoftSqlService' like:

public abstract class AbstractMicrosoftSqlService extends
AbstractSqlService {

@Override
protected String getConfiguredJdbcDriverName() {
return "com.microsoft.jdbc.sqlserver.SQLServerDriver";
}

@Override
protected String getConfiguredJdbcMappingName() {
return "jdbc:microsoft:sqlserver://<servername>:<port>";
}
}

7. Open the '*.product' files of your server bundle. Switch to the
'Dependencies' tab and add the created plugin
'org.eclipse.scout.rt.jdbc.microsoft'. (If you do not need the derby sql
service you can remove the bundle 'org.eclipse.scout.rt.jdbc.derby' from
the dependencies).

8. Switch to the Scout perspective and create a new Sql Service
'server/Common Services/Sql Services'. Use 'AbstractMicrosoftSqlService'
as a super type.

9. Override the 'getConfiguredJdbcMappingName' and replace <servername>
and <port>. If username and password is required override the methods
'getConfiguredUsername' and 'getConfiguredPassword'.

In some case you need also to write your own SQL Style (see
getConfiguredSqlStyle). For more information take a look at
org.eclipse.scout.rt.jdbc.derby bundle.

Hope it helped...

My guess is you are writing your own jdbc connection (db support bundle).

There is an other input from Lukas Huser on the forum:
build your own fragment containing the MySql jdbc driver

I opened new HowTo page on the wiki: Scout/HowTo/Write_a_jdbc_connection_bundle

I wonder how it is possible to merge both how to (fragment, plug-in ?)...
