how to convert java multipart file upload program to groovy - groovy

Question

Below is my code and log of the cast Exception
Getting the castException if i run the same code in groovy IDE (intelli idea)
import javax.net.ssl.HostnameVerifier;

String response = null;
System.out.println("hello");
String HOST_URI3 = "https://192.168:10443/srest/v1.0/";
String url = HOST_URI3 + "/updateBridgetData";
try {

params[2] = new NameValuePair("bridgetMetaData.bridgetKeyData.bridgetAppId", "10009959");
params[3] = new NameValuePair("bridgetMetaData.bridgetSource.fileName", "bundle.zip");
pm.setQueryString(params);
String sourceFile = "D:\\bundle\\bundle\\bundle.zip";
File f = new File(sourceFile);
Part[] parts = {new FilePart("bridgetMetaData.bridgetSource.bundledZipFile", f)};
pm.setRequestEntity(new MultipartRequestEntity(parts, pm.getParams()));
HttpClient hc = new HttpClient();
int RC = hc.executeMethod(pm);
System.out.println("Response Status Code : " + RC);
response = pm.getResponseBodyAsString();
System.out.println("The response is " + response);
} catch (Exception e) {
e.printStackTrace();
} finally {
httpclient.getConnectionManager().shutdown();
}
return response;
}

}
}

}
}

Answer 1

You need to use [] not {} when defining your Part[]
Part[] parts = [new FilePart("bridgetMetaData.bridgetSource.bundledZipFile", f)]
