Wrong bundle is used as server bundle [message #1403488]

Hi there,

I created my own JDBC bundle to load some own MySQL stuff. This works fine, but now the SDK takes this "com.example.jdbc.mysql" bundle as my server-bundle and the actual server bundle (com.example.server) is a "sub-component" of "com.example.jdbc.mysql".
This results into wrong destinations - e.g. when the search form wizard creates some services for the server.

The scout explorer looks as follows for the scout project:

com.example
|- com.example.client
|- com.example.shared
|- com.example.jdbc.mysql
   |- com.example.server
      |- ServerSession
      |- Services
      |- Lookup Services
      |- ....
   |- Services
   |- Lookup Services
   |- Common Services
   |- Libraries

so my question is: how does the SDK detect a server bundle. could it be that it is done via the manifest and the defined plug-in dependencies? Because my jdbc-bundle needs the org.eclipse.scout.rt.server for buddy class loading (to find and load the jdbc driver)...

Hi Dennis,

You are right, the tree is calculated using the dependencies of your bundle. And because your server bundle uses the mysql bundle, the server bundle is correctly shown below it.
If you don't like this view, you can configure the view of the scout explorer using the small triangle in the top right corner of the scout explorer view and customize the plugins shown.

In the wizards that create elements in the server plugin you can use drag-and-drop to move the elements into the right plugins.

If you don't want to do that everytime, you can define a target platform that includes the mysql plugin as binary jar file. Then you don't need it anymore in your workspace and binary bundles are never used in the wizards.

Hope this helps

Kind regards
matthias

Hi,

Thanks for the answer. The problem is not how it is shown. The problem is, the wizards don't work, because they create some stubs in the jdbc bundle and some other stubs in the server bundle. When I create a form, the formdata is generated into the jdbc-bundle, but without any annotations or methods/fields and this causes a missing service registration. I guess, this is due to the missing entries, because there the jdbc bundle does not use any extension points... Since the created forms and data classes are therefore corrupt, drag'n'drop does not work anymore... So all advantages of the scout sdk is gone and I have to correct all clases by hand - which is really annoying

Tried the "export as binary and import through the target platform" already, but this does not work. Because now I have no server part (either the server nor the jdbc bundle) in the scout view. In this case no com.example.server - just the client and shared component...

Next, I will try to transform the jdbc bundle into a fragment and hope that this will work...

For those how (will) get same problems: A fragment also does not work because the dependencies or the imports between the Scout framework, the server bundle and the fragment can not be resolved (due to cycles...)
My solution for now: moving all from the jdbc-plugin directly into the server bundle.

You can control where the elements are generated in the Step 2 of the "New Form" wizard. Have you tried it?

index.php/fa/18627/0/

You speak from missing stuff. Have you checked in the Error Log View if the SDK creates errors or warnings?

If so, we would be interested to improve Scout SDK.

That's what I said: Since the bundles are messy, the wizards don't work.

I went into further investigation, starting from an empty scout project.
The problem occurs when there are the follwing dependencies (in addition to the default dependencies):
the com.example.bundlebug.jdbc bundle depends on
- com.example.bundlebug.shared
- org.eclipse.scout.rt.server
the com.example.bundlebug.server depends on:
- com.example.bundlebug.jdbc

Then this looks like here:
index.php/fa/18631/0/

When I create a new form - lets say TestForm - the wizard shows:
index.php/fa/18632/0/

The TestFormData is not correctly annotated:

package com.example.bundlebug.shared.forms;

import org.eclipse.scout.rt.shared.data.form.AbstractFormData;

public class TestFormData extends AbstractFormData{

public TestFormData(){
}
}

The structure is now as follows:

index.php/fa/18633/0/

As you can see in the image following is wrong/missing:
- TestForm is missing and not created
- TestService is at the wrong place (which was obviously already in the wizard wrong)
- TestService is not registered in the extension point

Note that I search for the TestForm, so it is missing classes and we can exclude a scout-explorer-bug...

And yes, an error is thrown into the console (after clicking ok on the wizard):

org.eclipse.scout.sdk.ui

Thanks for the feedback. With the information you have provided, I could reproduce your case.

1/ I will inform the SDK Team, they should have a look at the NullPointerException.
I created Bug 440424 to track it.

2/ With the current state, in the second step of the wizard, you can drag and drop the items:

index.php/fa/18635/0/

If you put the "TestService" and the "Service Registration" items to your server node (com.example.server) it will work.

Ah, didn't know that it is possible to move items in the wizard. Since I merged the jdbc stuff into the server bundle, I don't have the problems anymore...
However, this is just a work around and does not directly solve the bug Wink

Hi Dennis & Jérémie,

This error happens when a service registration (or any other extension) should be added to a plugin not having a plugin.xml file. As a workaround until the bug is fixed just manually create the missing plugin.xml files.

For more details please see Bug 440424. Will be fixed for Luna SR1 release.

Kind regards and thank you for pointing that issue out!
