Method Detail

newBuilder

public static ClientBuilder newBuilder()

Create a new ClientBuilder instance using the default client builder implementation class provided by the JAX-RS implementation provider.

Returns:

new client builder instance.

newClient

public static Client newClient()

Create a new Client instance using the default client builder implementation class provided by the JAX-RS implementation provider.

Returns:

new client instance.

newClient

public static Client newClient(Configuration configuration)

Create a new custom-configured Client instance using the default client builder implementation class provided by the JAX-RS implementation provider.

Parameters:

configuration - data used to provide initial configuration for the new client instance.

Returns:

new configured client instance.

withConfig

public abstract ClientBuilder withConfig(Configuration config)

Set the internal configuration state to an externally provided configuration state.

Parameters:

config - external configuration state to replace the configuration of this configurable instance.

Returns:

the updated client builder instance.

sslContext

public abstract ClientBuilder sslContext(SSLContext sslContext)

Set the SSL context that will be used when creating secured transport connections to server endpoints from web targets created by the client instance that is using this SSL context. The SSL context is expected to have all the security infrastructure initialized, including the key and trust managers.

Setting a SSL context instance resets any key store or trust store values previously specified.

Parameters:

sslContext - secure socket protocol implementation which acts as a factory for secure socket factories or SSL engines. Must not be null.

Returns:

an updated client builder instance.

Throws:

NullPointerException - in case the sslContext parameter is null.

See Also:

keyStore(java.security.KeyStore, char[]), keyStore(java.security.KeyStore, String), trustStore(java.security.KeyStore)

keyStore

public abstract ClientBuilder keyStore(KeyStore keyStore,
                     char[] password)

Set the client-side key store. Key store contains client's private keys, and the certificates with their corresponding public keys.

Setting a key store instance resets any SSL context instance value previously specified.

Note that a custom key store is only required if you want to enable a custom setup of a 2-way SSL connections (client certificate authentication).

Parameters:

keyStore - client-side key store. Must not be null.

password - client key password. Must not be null.

Returns:

an updated client builder instance.

Throws:

NullPointerException - in case any of the supplied parameters is null.

See Also:

sslContext(javax.net.ssl.SSLContext), keyStore(java.security.KeyStore, String), trustStore(java.security.KeyStore)

keyStore

public ClientBuilder keyStore(KeyStore keyStore,
                     String password)

Set the client-side key store. Key store contains client's private keys, and the certificates with their corresponding public keys.

Setting a key store instance resets any SSL context instance value previously specified.

Note that for improved security of working with password data and avoid storing passwords in Java string objects, the keyStore(java.security.KeyStore, char[]) version of the method can be utilized. Also note that a custom key store is only required if you want to enable a custom setup of a 2-way SSL connections (client certificate authentication).

Parameters:

keyStore - client-side key store. Must not be null.

password - client key password. Must not be null.

Returns:

an updated client builder instance.

Throws:

NullPointerException - in case any of the supplied parameters is null.

See Also:

sslContext(javax.net.ssl.SSLContext), keyStore(java.security.KeyStore, char[]), trustStore(java.security.KeyStore)

trustStore

public abstract ClientBuilder trustStore(KeyStore trustStore)

Set the client-side trust store. Trust store is expected to contain certificates from other parties the client is you expect to communicate with, or from Certificate Authorities that are trusted to identify other parties.

Setting a trust store instance resets any SSL context instance value previously specified.

In case a custom trust store or custom SSL context is not specified, the trust management will be configured to use the default Java runtime settings.

Parameters:

trustStore - client-side trust store. Must not be null.

Returns:

an updated client builder instance.

Throws:

NullPointerException - in case the supplied trust store parameter is null.

See Also:

sslContext(javax.net.ssl.SSLContext), keyStore(java.security.KeyStore, char[]), keyStore(java.security.KeyStore, String)

hostnameVerifier

public abstract ClientBuilder hostnameVerifier(HostnameVerifier verifier)

Set the hostname verifier to be used by the client to verify the endpoint's hostname against it's identification information.

Parameters:

verifier - hostname verifier.

Returns:

an updated client builder instance.

build

public abstract Client build()

Build a new client instance using all the configuration previously specified in this client builder.

Returns:

a new client instance.
