Hi Holger,
Another way would be connecting to the database of MII using the JDBC connection of Java.
You can find more information here:
Getting a Connection to the Database - Using Java - SAP Library
MII creates a JDBC datasource named "XMIIDatasource". You can use that or create your own also.
This is the path for JDBC datasources in the net-weaver server:
Configuration-->Infrastructure-->Application Resources
Once you get the connection object then you can query any table in the net-weaver/MII database.
Each MDO is a table created in the net-weaver/MII database thus you need to know the name of table generated by MII. Table for MDO will have names like MDO and a number.
The before mentioned approach of making http call to MII is better, clean and easy way to execute the queries.
