Axis2 > Java Apache Axis2 has inbuilt support for Basic, NTLM and Proxy authentication via commons-httpclient-3.0. Basic and NTLM use preemptive authentication scheme of commons-httpclient.

Configuration for Proxy Authentication It has to be noted that Proxy Authentication via httpclient is available only with HTTP 1.0 version. Configuration for Proxy Authentication is available at deployment time (axis2.xml) or runtime.

1. Proxy Authentication at Deployment time In Axis2.xml, user will be able to find the following entry:

<parameter name="PROTOCOL" locked="false">HTTP/1.1 <parameter name="Transfer-Encoding" locked="false">chunked To enable proxy authentication:

<parameter name="PROTOCOL" locked="false">HTTP/1.0 <parameter name="PROXY" proxy_host="proxy_host_name" proxy_port="proxy_host_port" locked="true>userName:domain:passWord 2. Proxy Authenticaion at Runtime. In client or stub:

HttpTransportProperties.ProxyProperties proxyProperties = new HttpTransportProperties().new ProxyProperties();

proxyProperties.setProxyHostName("axis2"); proxyProperties.setProxyPort(9762); proxyproperties.setDomain("axis2/anon"); proxyproperties.setPassWord("passwd"); proxyproperties.setUserName("usernm"); //in order to makesure that we use HTTP 1.0 options.setProperty(MessageContextConstants.HTTP_PROTOCOL_VERSION, HTTPConstants.HEADER_PROTOCOL_10); options.setProperty(org.apache.axis2.transport.http.HTTPConstants.PROXY, proxyProperties); Basic and NTLM Authentication Axis2 uses commons-httpclient's preemptive authentication scheme to support Basic and NTLM Authentication.

1. To Enable Basic Authentication

HttpTransportProperties.BasicAuthentication basicAuthentication = new HttpTransportProperties().new BasicAuthentication(); basicAuthentication.setUsername("axis2"); basicAuthentication.setPassword("axis2"); options.setProperty( org.apache.axis2.transport.http.HTTPConstants.BASIC_AUTHENTICATION, basicAuthentication);

2. To Enable NTLM Authentication

HttpTransportProperties.NTLMAuthentication ntlmAuthentication = new HttpTransportProperties().new NTLMAuthentication(); ntlmAuthentication.setUsername("axis2"); ntlmAuthentication.setPassword("axis2"); ntlmAuthentication.setHost("axis2"); ntlmAuthentication.setPort(9443); ntlmAuthentication.setRealm("someRealm"); options.setProperty(

org.apache.axis2.transport.http.HTTPConstants.NTLM_AUTHENTICATION, ntlmAuthentication);

try { Service1Stub

spServer = new

Service1Stub("http://test001:9998/Service.asmx"); // NTLM Authentication List<String> authScheme = new ArrayList<String>(); authScheme.add(HttpTransportProperties.Authenticator.NTLM); HttpTransportProperties.Authenticator ntlm = new HttpTransportProperties.Authenticator(); ntlm.setAuthSchemes(authScheme); ntlm.setUsername("administrator"); ntlm.setPassword("1"); ntlm.setHost("test001"); ntlm.setPort(9998); ntlm.setDomain("sps2007"); Options options = spServer._getServiceClient().getOptions(); options.setProperty(HTTPConstants.AUTHENTICATE, ntlm); spServer._getServiceClient().setOptions(options); } catch (AxisFault e) { e.printStackTrace(); } // Base Authentication //

HttpTransportProperties.Authenticator authenticator = new

HttpTransportProperties.Authenticator(); //

List<String> authScheme = new ArrayList<String>();

//

authScheme.add(HttpTransportProperties.Authenticator.BASIC);

//

authenticator.setAuthSchemes(authScheme);

//

authenticator.setUsername("administrator");

//

authenticator.setPassword("1");

//

authenticator.setHost("test001");

//

authenticator.setDomain("sps2007");

//

authenticator.setPort(port);

// //

Options options = stub._getServiceClient().getOptions();

//

options.setProperty(HTTPConstants.AUTHENTICATE,

authenticator); //

stub._getServiceClient().setOptions(options);

//

PROXY Authentication

//

HttpTransportProperties.ProxyProperties proxyProperties

//

= new HttpTransportProperties.ProxyProperties();

//

proxyProperties.setProxyName("test001.sps2007.com");//test001

//

proxyProperties.setProxyPort(9998);

//

proxyProperties.setDomain("sps2007.com");

//

proxyProperties.setUserName("administrator");

//

proxyProperties.setPassWord("1");

//

Options options = stub._getServiceClient().getOptions();

//

options.setProperty(HTTPConstants.PROXY, proxyProperties);

//

stub._getServiceClient().setOptions(options);
