OBridge provides a simple Java source code generator for calling Oracle PL/SQL package procedures.

Supported input, output parameters and return values are:
  * BINARY_INTEGER
  * BOOLEAN
  * CHAR
  * CLOB
  * BLOB
  * DATE
  * NCHAR
  * NUMBER
  * NVARCHAR2
  * OBJECT - Oracle Object Type
  * PLS_INTEGER
  * TABLE - Table of Oracle Object Type
  * TIMESTAMP
  * VARCHAR2
  * RAW
  
The following types cannot be implemented, because JDBC driver does not supports them:
  * Types declared in source code
  * %ROWTYPE parameters
  
Generated code compiles with Java 1.6.

Usage
-----

Download the latest version from [releases](https://github.com/karsany/obridge/releases).

After downloading, create an XML configuration file:

```xml
<configuration>
	<jdbcUrl>jdbc:oracle:thin:scott/tiger@localhost:1521:xe</jdbcUrl> <!-- jdbc connection string for obridge -->
	<sourceRoot>.</sourceRoot> <!-- where to generate sources - related to this configuration file -->
	<rootPackageName>hu.obridge.test</rootPackageName> <!-- root Java package, generator builds the directory structure -->
	<packages>
		<entityObjects>objects</entityObjects> <!-- object types are going to this package -->
		<converterObjects>converters</converterObjects> <!-- converter util classes are going to this package -->
		<procedureContextObjects>context</procedureContextObjects> <!-- procedure parameter entities are going to this package -->
		<packageObjects>packages</packageObjects> <!-- procedure calling utility classes are going to this package -->
	</packages>
</configuration>
```
Run the generator:

	java -jar obridge.jar -c <obridge-config.xml>
		
OBridge connects to the specified database and generates the required classes.

Calling a PL/SQL procedure
--------------------------

For example you have the following PL/SQL code:

```sql
Create Or Replace Package simple_procedures is
  Function simple_func(a In Varchar2,
					   b In Out Varchar2,
					   c Out Varchar2) Return Number;
End simple_procedures;
```
Generated source:

```java
public class SimpleProcedures {
	public static SimpleProceduresSimpleFunc simpleFunc(String a, String b,  Connection connection) throws SQLException { ... }
}
```
You can call the SimpleProcedures.simpleFunc method:

```java
SimpleProceduresSimpleFunc ret = SimpleProcedures.simpleFunc("hello", "world", conn); // conn is the database connection
```
Return object will hold the input and output parameters, converted to Java types.
```java
public class SimpleProceduresSimpleFunc {

	private BigDecimal functionReturn;
	private String a;
	private String b;
	private String c;
	
	// getters, setters

}
```
