Tutorial: RUI with Database Lesson 8 [message #850034]

Had completed the codes following Tutorial: RUI with Database Lesson 8 (using EDT 0.8.0).

When preview, encountered failure "An exception occurred while calling a service." and "Detail 3: The URL used to invoke the service is blank. Specify a URL that points to the service."

The only abnormal code is that the "using dedicatedServiceBinding" is not recognized by Eclipse IDE. The followings are complete codes given by Tutorial for EDIT 0.8.0:

function readFromTable()
call dbService.getAllPayments()
using dedicatedServiceBinding
returning to updateAll
onException serviceExceptionHandler;
end

What went wrong? Anyone?

Hi,
The tutorial has steps for EDT 0.7 and EDT 0.8. Since you are using EDT 0.8, and the syntax has changed to no longer use @dedicatedService, you should use:

for service binding:

  dbService SQLService? ;
  dbServiceBinding HTTPProxy ;

and call statement:

function readFromTable()
     call dbService.getAllPayments() 
        using dedicatedServiceBinding
        returning to updateAll
        onException serviceExceptionHandler;
  end

Yes, Theresa. I have followed EDT 0.8 codes exactly as you said.

But Eclipse IDE doesn't accept "dedicatedServiceBinding" in readFromTable() function.

If I remark "using dedicatedServiceBinding" statement, errors mentioned above appear.

By the way, how should I change the following to use Mysql database instead of Derby?

package services;

service SQLService
ds SQLDataSource? { @Resource { uri="binding:Derby" } } ; // EDT 0.8.O syntax
end

ah I think it's a typo...
should be
using dbServiceBinding (which you defined earlier, not using dedicatedServiceBinding)

We'll update the tutorial.

as for the database, I haven't tried MySQL but here's some info on defining SQL resources:

http://wiki.eclipse.org/EDT:Resource_Binding_Databases

Maybe someone else has used MySQL can comment?

Yes, it is typo.

However using MySQL as database is still not successful. Appreciate anyone can help.

Thanks.
