Working with Proxy Servers and Proxy Authentication

In some cases, the Web service client must go through a proxy server to reach the PPM server. In this case, a proxy server must be specified when you establish a connection. Otherwise, a connection time out error or no connection exception will occur.

There are two solutions available (depending on whether you want all or some calls to go through the proxy):

• Configure proxy by using client-axis2.xml.

• Configure proxy through java code.

All Web Service Calls Go Through Proxy: Configure Proxy By Using client-axis2.xml

This configuration forces all Web service calls from the Web service toolkit to go through the proxy. This file locates in the following directory:
<webservice_toolkit>/java/conf

Add following XML configuration:

<transportSender
name=""
class="org.apache.axis2.transport.http.CommonsHTTPTransportSend
er">
     <parameter name="PROTOCOL" locked="false">HTTP/1.1</
parameter>
<parameter
    name="PROXY"
    proxy_host="proxy_host_name"
    proxy_port="proxy_host_port"
       locked="true>
           userName:domain:password
    </parameter>
</transportSender>

If authentication is not available, fill

"userName:domain:password" as "anonymous:anonymous:anonymous."

Some Web Service Calls Go Through Proxy: Configure Proxy By Using Java Code

If only a selected number of operations in the toolkit should go through the proxy, choose this solution.

Add the following method in the client code:

public void setProxy(Stub stub, String proxyHost, int
proxyPort) {
      // get options
      Options options = stub._getServiceClient().getOptions();
      if (options == null) {
         options = new Options();
         stub._getServiceClient().setOptions(options);
      }

      HttpTransportProperties.ProxyProperties proxyProperties = new
HttpTransportProperties.ProxyProperties();
      proxyProperties.setProxyName(proxyHost);
      proxyProperties.setProxyPort(proxyPort);
      options.setProperty(HTTPConstants.PROXY,
proxyProperties);
   }

Call this method before you invoke a Web service operation. For example:

DemandServiceStub stub = new DemandServiceStub(ctx,
serviceURL);
setProxy(stub, "proxy.hp.com", 8888);
