All Connectors

Web Service Consumer Reference

Complete Code Example

The component formerly known as the SOAP Connector is now known as the CXF Component. It should not be confused with the Web Service Consumer.

Elements and Attributes

Studio Palette XML Element Use

Web Service Consumer

ws:consumer

Use to consume a SOAP Web service from within a Mule application.

Child Element Attribute Value Attribute Req’d Attribute Description

ws:wss-sign

tlsContext-ref

x

References a TLS context where to obtain a Key Store used to add a soap header with a signature to outgoing messages.

The sign security policy adds a signature to the header of the SOAP request. The signature is generated using the private key of the client. Therefore, a reference to a TLS Context must be provided, and this context must contain the definition of a key-store. The private key of this key-store is used to generate the signature.

<tls:context name="tlsContext">
   <tls:key-store path="path" keyPassword="pass" password="pass" alias="keyalias" />
</tls:context>

<ws:consumer-config serviceAddress="http://localhost/test" wsdlLocation="Test.wsdl"
                    service="TestService" port="TestPort" name="wsConfig">
        <ws:security>
            <ws:wss-sign tlsContext-ref="tlsContext" />
        </ws:security>
</ws:consumer-config>
Child Element Attribute Value Attribute Req’d Attribute Description

ws:wss-verify-signature

tlsContext-ref

x

References a TLS context where to check a Trust Store to certify the signatures on incoming messages.

The verify-signature security policy allows the client to validate a signature that was added by the server to the SOAP response. In order to perform this validation, a reference to a TLS Context must be provided, and this context must contain a trust-store. The trust-store must contain the certificate of the server that is signing the response.

<tls:context name="tlsContext">
   <tls:trust-store path="trustStore" password="pass" />
</tls:context>

<ws:consumer-config serviceAddress="http://localhost/test" wsdlLocation="Test.wsdl"
                    service="TestService" port="TestPort" name="wsConfig">
        <ws:security>
            <ws:wss-verify-signature tlsContext-ref="tlsContext" />
        </ws:security>
</ws:consumer-config>
Child Element Attribute Value Attribute Req’d Attribute Description

ws:wss-encrypt

tlsContext-ref

x

References a TLS context where to obtain a Trust Store to use in the encryption of outgoing messages. This encryption occurs at SOAP level, not at HTTP level

alias

x

Alias of the key to use inside the trust-store

The encrypt security policy allows the client to encrypt the SOAP body of the request. The body is encrypted using the public key of the server, so a TLS Context with a trust-store must be provided. As the trust-store may contain many entries for trusted servers, the alias of the key to use must be also specified as an attribute:

<tls:context name="tlsContext">
   <tls:trust-store path="trustStore" password="pass" />
</tls:context>

<ws:consumer-config serviceAddress="http://localhost/test" wsdlLocation="Test.wsdl"
                    service="TestService" port="TestPort" name="wsConfig">
        <ws:security>
            <ws:wss-encrypt tlsContext-ref="tlsContext" alias="keyalias" />
        </ws:security>
</ws:consumer-config>
Take into account that this encryption occurs at SOAP level. If you wish to encrypt your messages at HTTP level, then you must do that through having your WSC reference a different http-request-config element from the default, which in turn must reference a TLS element.
Child Element Attribute Value Attribute Req’d Attribute Description

ws:wss-decrypt

tlsContext-ref

x

References a TLS context where to obtain a Key Store to use for decrypting incoming messages. This decryption occurs at SOAP level, not at HTTP level.

The decrypt security strategy allows the client to decrypt a SOAP response that is encrypted by the server. A reference to a TLS Context with a key-store must be provided. The private key in the keystore will be used to decrypt the response.

<tls:context name="tlsContext">
   <tls:key-store path="path" keyPassword="pass" password="pass" alias="keyalias" />
</tls:context>

<ws:consumer-config serviceAddress="http://localhost/test" wsdlLocation="Test.wsdl"
                    service="TestService" port="TestPort" name="wsConfig">
        <ws:security>
            <ws:wss-decrypt tlsContext-ref="tlsContext" />
        </ws:security>
</ws:consumer-config>
Take into account that this decryption occurs at SOAP level. If you wish to decrypt messages at HTTP level, then you must do that through having your WSC reference a different http-request-config element from the default, which in turn must reference a TLS element.
