Stubport._setPropertyweblogic.wsee.connection.transportinfo,info; set proxy-authentication info
Stubport._setPropertyweblogic.webservice.client.proxyusername,user; Stubport._setPropertyweblogic.webservice.client.proxypassword,pass;
invoke String s = port.echoHello World;
System.out.printlnecho: + s; }
}
The sections of the preceding example to note are as follows:
■
Import the required java.net. classes: import java.net.Proxy;
import java.net.InetSocketAddress;
■
Import the WebLogic HttpTransportInfo API: import weblogic.wsee.connection.transport.http.HttpTransportInfo;
■
Create a Proxy object that represents the proxy server: Proxy p = new ProxyProxy.Type.HTTP, new InetSocketAddressproxyHost,
Integer.parseIntproxyPort; The proxyHost and proxyPort arguments refer to the host computer and port
of the proxy server.
■
Create an HttpTransportInfo object and use the setProxy method to set the proxy server information:
HttpTransportInfo info = new HttpTransportInfo; info.setProxyp;
■
Use the weblogic.wsee.connection.transportinfo WebLogic stub property to set the HttpTransportInfo object on the JAX-RPC stub:
Stubport._setPropertyweblogic.wsee.connection.transportinfo,info;
■
Use weblogic.webservice.client.proxyusername and weblogic.webservice.client.proxypassword
WebLogic-specific stub properties to specify the username and password of a user who is authenticated to
access the proxy server: Stubport._setPropertyweblogic.webservice.client.proxyusername,user;
Stubport._ setPropertyweblogic.webservice.client.proxypassword,pass;
Alternatively, you can use the setProxyUsername and setProxyPassword
methods of the HttpTransportInfo API to set the proxy username and password, as shown in the following example:
info.setProxyUsernamejuliet.getBytes; info.setProxyPasswordsecret.getBytes;
6.5.2 Using System Properties to Specify the Proxy Server
To use system properties to specify the proxy server, write your client application in the standard way, and then specify system properties when you execute the client
application.
6-16 Getting Started With JAX-RPC Web Services for Oracle WebLogic Server
You have a choice of using standard Java system properties or historical WebLogic properties. If the proxySet system property is set to false proxySet=false, proxy
properties will be ignored and no proxy will be used.
The following table summarizes the Java system properties. In this case, the proxySet system property must not be set.
The following excerpt from an Ant build script shows an example of setting Java system properties when invoking a client application called
clients.InvokeMyService :
target name=run-client java fork=true
classname=clients.InvokeMyService failonerror=true
classpath refid=client.class.path arg line={http-endpoint}
jvmarg line= -Dhttp.proxyHost={proxy-host}
-Dhttp.proxyPort={proxy-port} -Dhttp.nonProxyHosts={mydomain}
java target
The following table summarizes the WebLogic system properties. In this case, the proxySet system property must be set to true.
Table 6–3 Java System Properties Used to Specify Proxy Server
Property Description
http.proxyHost=proxyHost or
https.proxyHost=proxyHost Name of the host computer on which the proxy server is
running. Use https.proxyHost for HTTP over SSL.
http.proxyPort=proxyPort or
https.proxy.Port=proxyPort Port to which the proxy server is listening. Use https.proxyPort
for HTTP over SSL.
http.nonProxyHosts= hostname | hostname | ...
List of hosts that should be reached directly, bypassing the proxy. Separate each host name using a | character. This
property applies to both HTTP and HTTPS.
Table 6–4 WebLogic System Properties Used to Specify the Proxy Server
Property Description
proxySet=true Flag that specifies that the historical WebLogic proxy properties
should be used. proxyHost=proxyHost
Name of the host computer on which the proxy server is running.
proxyPort=proxyPort Port to which the proxy server is listening.
weblogic.webservice.client. proxyusername=username
Username used to access the proxy server. weblogic.webservice.client.
proxypassword=password Password used to access the proxy server.
