What code?

What version of Hudson are you running? Do you have authentication on?

Thanks.

Hi All,

Running Hudson as the service in 8080 port.Iam have wrote sample java code to create job in hudson and trigger it from the remote windows machine.The config.xml is taken from the jobs folder of another job:
But it is throwing 500 error(Response status code: 500

package createJob;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileNotFoundException;

import org.apache.commons.httpclient.HttpClient;
import org.apache.commons.httpclient.methods.InputStreamRequestEntity;
import org.apache.commons.httpclient.methods.PostMethod;




public class CreateJob {

	public static void main(String[] args) throws FileNotFoundException {
		String strURL = "htt://XXXX:8080/createItem?name=findsresume123";
		File input = new File("C:\\Users\\XXXX\\Desktop\\config.xml");
		PostMethod post = new PostMethod(strURL);
		post.setRequestEntity(new InputStreamRequestEntity(new FileInputStream(input), input.length()));


		post.setRequestHeader("Content-type", "text/xml; charset=ISO-8859-1");
		HttpClient httpclient = new HttpClient();

		try {

            int result = httpclient.executeMethod(post);
            System.out.println("Response status code: " + result);
            System.out.println("Response body: ");
            System.out.println(post.getResponseBodyAsString());
		}
		catch (Exception e) {
            // Release current connection to the connection pool 
            // once you are done
            post.releaseConnection();
        }

	}

You should not use createItem directly. You should use the remote Access API as explained here http://wiki.hudson-ci.org/display/HUDSON/Remote+access+API.

Hi,
I have configured security and enabled it as mentioned in the url:
http://wiki.hudson-ci.org/display/HUDSON/Standard+Security+Setup
I have created users and give all permissions to create job
I have modified the code as accessing the url with username and password which i created now.
Create Job
I have created the job as mentioned below in the site.

To create a new job, POST config.xml to http://your_server/createItem (copy url) with query parameter name=JOBNAME.
You'll get 200 status code if the creation is successful, or 4xx/5xx code if it fails. config.xml is the format Hudson uses to store the job in the file system, so you can see examples of them in /var/lib/hudson.

I have tried the code as mentioned in the site:"http://wiki.hudson-ci.org/display/HUDSON/Authenticating+scripted+clients"

There also they have used the createItem directly.

Can you please explain briefly,so that it can be useful for me.
Thanks.

Hi Winston,

Now iam getting problem in triggering the build remotely.
The code is

public String buildjob()
{

String strURL1="htt://xxxx:8080/job/"+jobname+"/build?delay=0sec";
PostMethod post = new PostMethod(strURL1);
HttpClient httpclient = new HttpClient();
httpclient.getState().setCredentials(new AuthScope("xxxx", 8080, "realm"),new UsernamePasswordCredentials("xxxx", "zzzz"));
httpclient.getParams().setAuthenticationPreemptive(true);
try {

int result = httpclient.executeMethod(post);

System.out.println("Build Response status code: " + result);
System.out.println("Build Response body: ");
System.out.println(post.getResponseBodyAsString());

}
}
catch (Exception e) {
// Release current connection to the connection pool
// once you are done
post.releaseConnection();
}
return res;
}

Iam getting 302 response code.buthe build is happening at hudson end.i was not able to get the build is success/failure.
Please share some idea to get the build no,build status and check the above code and let me know.
Thanks
