Oracle Stored Procedures with Custom Java Code

Togheter with the Oracle´s official Structured Query Language PL/SQL, and the open-source statistical analysis language bundled in the Oracle Data Mining package, R, we also have the possibilty to use and integrate another great technology in our database: Java, the world's number one programming language in enterprise environments.

public static int your_function_name(String separator, String args) {     ...your java code...}
