How to save data in Master-Detail tables with seq PKs in Java?

GadoMay 23 2017 — edited May 23 2017

Hello Experts,

I'm building a Sales Order application.

And now i'm stuck in how to save the sales Order.

I know how to insert records in a single database table ... but now i want to save in both tables.

I want to insert a record in the master SalesOrder table and the items in the detail SalesOrderItems at the same time.

The Primary keys in both tables are assigned using a database sequence so i don't know how to handle the relation between them

There is no way to know the SalesOrder (Master)'s PK to assign as a FK in the SalesOrderItems (Detail) table at the time i'm saving the data.

Is this possible?

Thank you for your time

Gado

Also check the JDev project properties for the setting in the compiler section.

I think at runtime also your weblogic (jvm) should support UTF-8. Can you please set utf-8 encoding for JVM by modifying setDomainEnv.sh/setDomainEnv.cmd file present in you domain/bin directory.

You may need to add JAVA_OPTIONS="$JAVA_OPTIONS -Dfile.encoding=utf8"  in that file.


Thanks

thanks for your reply ... i searched for that file but i didn't find it

C:\Oracle\keemm\Middleware\Oracle_Home\wlserver\server\bin

is this the right path ?!

SanjeevChauhan

No. You need to check your domain location. If you are using Jdev to run application then domain will be under system directory. It is generally (if not changed by environment variable) is located under C:\Users\<yourusername>\AppData\Roaming\JDeveloper\<yoursystemdirectorybasedonjdev-version>/DefaultDomain/bin

Thanks

Hi Kareem,

If you are not able to find the path what you can do is that open jdeveloper and choose run-->start weblogic server.

Check your console window, it will show you your path where this file.

It should help you,
