If i want to invoke a geomesa wps service, i can write code like this:
HttpURLConnection conn = connfactory.openConnection();
conn.setRequestProperty("Content-Type", "text/xml");
conn.setRequestMethod("POST");
OutputStreamWriter out = new OutputStreamWriter(conn.getOutputStream());
out.write(document.asXML());
out.close();
//connect to the http service
........
this is a java program. Variable 'document' is a XML element and it is read from a XML file. if i want to generate this xml file , i must construct this file using a xml tool like dom4j. this is very complicated and time-consuming. Can i generate this xml file using a java object like "wps:datainputs"?
for example like this
wps.datainputs wps1 = new wps:datainputs();
wps.input.Identifilter = new filter();
Xml xml = wps1.toXml();
How can I implement this?
thanks very much in advance.
the xml file like the below:
<?xml version="1.0" encoding="UTF-8"?>
<wps:Execute version="1.0.0" service="WPS"
