Bitwise Operations in OSB and Oracle SOA

Sometimes you need to manipulate integers on bit level. Both Oracle Service Bus and Oracle SOA does not have any native solution for bitwise operations. You need to create a custom jar in OSB or you need to use java embedding in Oracle SOA BPEL.

You can download custom jar file for bitwise operations to use in OSB proxy service. The class file has 7 different methods:

BitwiseAND: Bitwise AND operator compare corresponding bits of two operands. If both bits are 1, it gives 1. If either of the bits is not 1, it gives 0. It’s denoted by &.

public static int BitwiseAND(int param1, int param2) {
		int result= param1 & param2;
		return result;
}

BitwiseOR: Bitwise OR operator compares corresponding bits of two operands. If either of the bits is 1, it gives 1. If not, it gives 0. It’s denoted by |.

public static int BitwiseOR(int param1, int param2) {
		int result= param1 | param2;
		return result;
}

BitwiseComplement: Bitwise complement operator means bit negation. It takes every single bit of the number and flips its value. That is - 0 becomes 1 and vice versa. It is denoted by ~.

public static int BitwiseComplement(int param) {
		int result= ~param;
		return result;
}

BitwiseXOR: Bitwise XOR operator compares corresponding bits of two operands. If corresponding bits are different, it gives 1. If corresponding bits are equal, it gives 0. It’s denoted by ^.

public static int BitwiseXOR(int param1, int param2) {
		int result= param1 ^ param2;
		return result;
}

SignedLeftShift: This operator shifts a bit pattern to the left by the certain number of specified bits, and zero bits are shifted into the low-order positions. It’s denoted by «.

public static int SignedLeftShift(int param1, int param2) {
		int result= param1 << param2;
		return result;
}

SignedRightShift: This operator shifts a bit pattern to the right by the certain number of specified bits. It’s denoted by ».

public static int SignedRightShift(int param1, int param2) {
		int result= param1 >> param2;
		return result;
}

UnsignedRightShift: This operator shifts all the bits to the right and pads the result with zeros from the left. It’s denoted by »>.Signed and unsigned right shifts have the same result for positive numbers.

public static int UnsignedRightShift(int param1, int param2) {
		int result= param1 >>> param2;
		return result;
}
