Grails GORM mapping id column using sequence

I work with grails 2.2.4 and legacy database. The legacy database is using postgreSQL. The primary key filed is hdsj_id (bigserial).

class TableHeaderSuratJalan {

 // a lot of field
 ...

 static mapping = {
  id column: "hdsj_id", generator: "sequence", params: [sequence:"table_header_surat_jalan_hdsj_id_seq"]
  version false
 }

}

We need to specify the sequence name, in this example my sequence's name is table_header_surat_jalan_hdsj_id_seq. By default grails will use hibernate_sequence

How to change Grails default port

If we run : grails run-app
By default the grails will listen at port : 8080

We can change by default port by run this command :
grails run-app -Dserver.port=9000
This command will make the grails listen to the port 9000

Another way is by editing the BuildConfig.groovy
Add the following line :
grails.server.port.http = 9000

NB: I use grails 2.2.4

Enable .NET 4 on IIS 6

After installing .NET Framework 4, IIS 6 is not directly enable the .NET 4. Run this command to check : 

cd \windows\system32\

iisext.vbs /ListFile

I got a problem when enable .NET 2 and .NET 4 simultaneously. So, I disable the .NET 2 and enable the .NET 4, by run this command :

C:\WINDOWS\system32>iisext.vbs /disfile C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\aspnet_isapi.dll

C:\WINDOWS\system32>iisext.vbs /EnFile C:\WINDOWS\Microsoft.NET\Framework\v4.0.30319\aspnet_isapi.dll

Restart IIS and the .NET 4 should be work.
