Axis2: Facing proxy issue
Hi,
Please find below Client.java.
I am using axis2 1.5.2 libraries and eutil_axis2.jar.
Client is an example program(http://www.ncbi.nlm.nih.gov/books/NBK55696/), which I am trying to execute. I have following step mention in "Using Eclipse for development" section, but it is giving below error
org.apache.axis2.AxisFault: Connection timed out: connect

I set proxy arguments as jvm arguments(-Dhttp.proxySet=true -Dhttp.proxyHost=myhost -Dhttp.proxyPort=8080 -Dhttp.proxyUser=username -Dhttp.proxyPassword=password), but it gives below error:
before run_eSearch

I am getting above error when I try to set proxy settings into System properties as below:
System.setProperty("http.proxySet", "true");
System.setProperty("http.proxyHost", "");
System.setProperty("http.proxyPort", "8080");
System.setProperty("http.proxyUser", "username");
System.setProperty("http.proxyPassword", "password");
Authenticator.setDefault(new Authenticator() {
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication("DOMAIN"+"\\"+"username", "password".toCharArray());
}
});
I tried to search solution for it and found below one:
private static void test(ServiceClient client){
final String proxyUser = "username";
final String proxyPassword = "password";
//Authenticator.setDefault(new ProxyAuthenticator(proxyUser, proxyPassword));
Authenticator.setDefault(new Authenticator() {
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication("DOMAIN"+"\\"+proxyUser, proxyPassword.toCharArray());
}
});
Properties props = System.getProperties();
String proxyHost = "Hostname";
props.put("http.proxyHost", proxyHost);
String proxyPort = "8080";
props.put("http.proxyPort", proxyPort);
props.put("http.proxyUser", proxyUser);
props.put("http.proxyPassword", proxyPassword);
props.put("https.proxyHost", proxyHost);
props.put("https.proxyPort", proxyPort);
props.put("https.proxyUser", proxyUser);
props.put("https.proxyPassword", proxyPassword);
/*-*/
HttpTransportProperties.Authenticator authentication = new
HttpTransportProperties.Authenticator();
authentication.setUsername(proxyUser);
authentication.setPassword(proxyPassword);
authentication.setHost(proxyHost);
authentication.setPort(Integer.parseInt(proxyPort));
/*-*/
HttpTransportProperties.ProxyProperties proxyProperties = new
HttpTransportProperties.ProxyProperties();
proxyProperties.setProxyName(proxyHost);
proxyProperties.setProxyPort(Integer.parseInt(proxyPort));
proxyProperties.setUserName(proxyUser);
proxyProperties.setPassWord(proxyPassword);
/*-*/
/*ServiceClient client = new ServiceClient();
client = new ReportingServiceStub(address)._getServiceClient();*/
/*-*/
Options options1 = new Options();
options1 = client.getOptions();
options1.setProperty(HTTPConstants.PROXY, proxyProperties);
options1.setProperty(HTTPConstants.HTTP_PROTOCOL_VERSION,
HTTPConstants.HEADER_PROTOCOL_10);
options1.setProperty(HTTPConstants.AUTHENTICATE, authentication);
options1.setProperty(AuthPolicy.AUTH_SCHEME_PRIORITY,
AuthPolicy.NTLM);
client.setOptions(options1);
/*-*/
Options options2 = new Options();
//options2.setTo(new EndpointReference(address));
options2.setAction("urn:getReportingData");
client.setOptions(options2);
/*-*/
/* OMElement res = client.sendReceive(createPayLoad());
System.out.println(res.toString());*/
}
But it gives below exception:
java.lang.NullPointerException

System.out.print(res.getIdList().getId()[i] + " ");
}
System.out.println();
}
catch (Exception e) { System.out.println(e.toString());
e.printStackTrace();}
}
}
Can anyone please help me to resolve this problem?
Thanks and Regards,
