===== =====
A Java implementation for the Bitmessage protocol. To build, use command `gradle build`. Note that for some tests to run, a standard Bitmessage client needs to run on the same system, using port 8444 (the default port). A Java implementation for the Bitmessage protocol. To build, use command `gradle build` or `./gradlew build`.
Please note that development is still heavily in progress, and I will break the database a lot until it's ready for prime time. Please note that development is still heavily in progress, and I will break the database a lot until it's ready for prime time.

Setup
-----
Add Jabit as Gradle dependency:
```Gradle
compile 'ch.dissem.jabit:jabit-domain:0.2.0'
```
Unless you want to implement your own, also add the following:
```Gradle
compile 'ch.dissem.jabit:jabit-networking:0.2.0'
compile 'ch.dissem.jabit:jabit-repositories:0.2.0'
```
And if you want to import from or export to the Wallet Import Format (used by PyBitmessage) you might also want to add:
```Gradle
compile 'ch.dissem.jabit:jabit-wif:0.2.0'
```
Usage
-----
First, you'll need to create a `BitmessageContext`:
```Java
JdbcConfig jdbcConfig = new JdbcConfig();
BitmessageContext ctx = new BitmessageContext.Builder()
.addressRepo(new JdbcAddressRepository(jdbcConfig))
.inventory(new JdbcInventory(jdbcConfig))
.messageRepo(new JdbcMessageRepository(jdbcConfig))
.nodeRegistry(new MemoryNodeRegistry())
.networkHandler(new NetworkNode())
.build();
```
This creates a simple context using a H2 database that will be created in the user's home directory. Next you'll need to
start the context and decide what happens if a message arrives:
```Java
ctx.startup(new BitmessageContext.Listener() {
@Override
public void receive(Plaintext plaintext) {
// TODO: Notify the user
}
});
```
Then you might want to create an identity
```Java
BitmessageAddress identity = ctx.createIdentity(false, Pubkey.Feature.DOES_ACK);
```
or add some contacts
```Java
BitmessageAddress contact = new BitmessageAddress("BM-2cTarrmjMdRicKZ4qQ8A13JhoR3Uq6Zh5j");
address.setAlias("Chris");
ctx.addContact(contact);
```
to which you can send some messages
```Java
ctx.send(identity, contact, "Test", "Hello Chris, this is a message.");
```
