Jasper Report calling in ASP.Net displays 405 Method Not Allowed error

Posted on January 13, 2020 at 9:51pm

Hi,

I want to call the jasper report in ASP.NET web application.
So I done the following implementation

1. Created Test Report (TestReport.jrxml file) in Jasper Report Studio. Currently report has no parameter.
2. Added report in Jasper Report Server.

3. Tested above report in Jasper Report Server. It loads the data properly.
4. Now, I want to call that report in Asp.net, so added following code

public void DownloadReport()
{
WebClient httpclient = new WebClient();

//Authentication credentials
httpclient.Credentials = new NetworkCredential("jasperadmin", "jasperadmin");

httpclient.Headers.Add("Content-Type", "application/x-www-form-urlecoded");

string requestXml;

            /*Report without parameter*/
            requestXml = "<resourceDescriptor name=\"TestReport\" wsType=\"reportUnit\" uriString= \"/jasperserver/rest/reports/TestReport\"";
            requestXml += " isNew=\"false\">";
            requestXml += "</resourceDescriptor>";

string uploadReport = "http://localhost:8080/jasperserver/rest/reports/TestReport?RUN_OUTPUT_FORMAT=PDF";

//Sent PUT
string requestAllResult = httpclient.UploadString(uploadReport, "PUT", requestXml);

            //Extract uuid, filename is always report
            System.Xml.XmlDocument doc = new System.Xml.XmlDocument();
            doc.LoadXml(requestAllResult);

XmlNode node = doc.DocumentElement.SelectSingleNode("uuid");
string uuid = node.InnerText;

            //Build GET Url
            string reportURL = "http://localhost:8080/jasperserver/rest/reports/";
            reportURL += uuid;
            reportURL += "?file=report";

            //Get Report
            string report;
            //Get Session Cookie
            string session = httpclient.ResponseHeaders.Get("Set-Cookie");
            //Set Session Cookie
            httpclient.Headers.Add("Cookie", session);

//Get Report
report = httpclient.DownloadString(reportURL);
}

But after running code, 405 Method not allowed error is occurred at following line.
string requestAllResult = httpclient.UploadString(uploadReport, "PUT", requestXml);
