Changed resource binding in 0.8.2 compared to 0.8.1 ? [message #1003656]

Are there any changes in the resource binding from EDT 0.8.1 to 0.8.2?

I use this notation in the code

ds SQLDataSource?{@Resource{uri = "binding:i5DB" }};

to get a SQLDataSource instance. i5DB is the name of a connection profile defined in the workspace. The .egldd file refers to it. i5DB is used to connect to an AS/400. The little test is written as a program part that is just started with "run as a main application". It works with EDT 0.8.1 but not with 0.8.2. The datasource contains always null, so I get a null pointer exception. I used a new workspace and created everything from scratch with the exception of the program source which I copied from the old workspace.

Any idea what's wrong here?

TIA,

Wilfried Reinoehl

Thank you Richard, I already checked this page but it does not help.

Is there anybody who made successful SQL accesses from EDT 0.8.2 to an AS/400?

TIA,

Wilfried Reinoehl

Just ran a quick test and was successful. (Used a simple Rich UI though ... not a "run as a main application" approach.) No changes to my code or binding from 0.8.1 other than to include the now-required explicit imports.

Did you set up a connection under Window -> Preferences -> Data Management -> Connectivity -> Driver management?

Thank you Dan. I already had a connection set-up.

I found a workaround with an alternative notation. So I am sure, that it is a bug.

// DOES NOT WORK.
//private ds SQLDataSource?{@Resource{uri = "binding:i5DB" } };

// WORKAROUND with alternative notation.
private ds SQLDataSource? =
Resources.getResource("binding:i5DB");

I received an NPE when running a quick test as well. There seems to be a bug where generation is not producing intialization code for global variables that specify the @Resource annotation. Variables that are defined local to a function and specify this annotation are generated correctly. I have opened a bug for this problem:

https://bugs.eclipse.org/bugs/show_bug.cgi?id=398841

If your SqlDataSource variable is defined as global, you will need to use the Resources.getResource() workaround you mentioned. Alternatively, if you can move the variable into a function, it should generate correctly.

Sorry for the inconvenience,

Paul
