To do so I have to deliberately break the application and so I need the source. I have an earlier version of the application, but not the sources. So I have to go to the latest MedRec. I actually like that, because it looks more modern.
The MedRec application is available if you install WebLogic with samples.
You can run the script demo_oracle.ddl from against the database:
$WL_HOME/samples/server/examples/src/examples/common/ddl
The medrec.ear can be found at:
$WL_HOME/samples/server/medrec/dist/standalone
I ran in quite some confusion and frustration, but I found that this combination, although from the same samples folder, does not work. Not only this medrec.ear expects the tables in plural (PRESCRIPTIONS) where the script creates them in singular (PRESCRIPTION), it expects a separate DRUGS table with a foreign key column DRUG_ID in PRESCRIPTIONS. And a few other changes.
I had a version of the scripts from earlier versions of WebLogic's MedRec. Based the exceptions in the server log, I refactored/reverse engineered the scripts.
Using those I could succesfully login and view the Patient records of fred@golf.com:
First we need to create a a schema using createDBUserMedrec.sql:
prompt Create user medrec with connect, resource roles; grant connect, resource to medrec identified by welcome1; alter user medrec default tablespace users temporary tablespace temp; alter user medrec quota unlimited on users;
Drop tables (if needed) using medrec_dropall.sql:
DROP TABLE "MEDREC"."ADMINISTRATORS"; DROP TABLE "MEDREC"."OPENJPA_SEQUENCE_TABLE"; DROP TABLE "MEDREC"."PATIENTS"; DROP TABLE "MEDREC"."PATIENTS_RECORDS"; DROP TABLE "MEDREC"."PHYSICIANS"; DROP TABLE "MEDREC"."PRESCRIPTIONS"; DROP TABLE "MEDREC"."DRUGS"; DROP TABLE "MEDREC"."RECORDS"; DROP TABLE "MEDREC"."RECORDS_PRESCRIPTIONS";
Create the tables using medrec_tables.sql:
