Two things require minor corrections (1) Content-Type HTTP POST per default uses so called URL encoding when submitting HTML forms. Setting the content type to 'text/plain' may cause some web servers to misinterpret the request parameters Try this instead postmethod.setRequestHeader( "Content-Type", "application/x-www-form-urlencoded; charset=utf-8"); (2) Request parameters This operation is completely redundant new String(((String) paramList.get(paramName)).getBytes("UTF-8"),"UTF-8") As far as I understand it produces exactly the same Unicode string // Assign parameters into post method Iterator it = paramList.keySet().iterator(); while (it.hasNext()) { String paramName = (String) it.next(); postmethod.addParameter(paramName, paramList.get(paramName)); } HttpClient will do all the charset conversion for you. Just make sure the charser attribute of the Content-Type is set For details please refer to the HttpClient encoding guide http://jakarta.apache.org/commons/httpclient/charencodings.html Hope this helps Oleg On Wed, 2004-10-13 at 13:22, Ramiel Fong wrote: > Hi~! > > Thanks in advance for those who will be looking into my problem. > > I am having difficulty in sending chinese characters via postmethod. > > // Create an instance of HttpClient > HttpClient httpclient = new HttpClient(); > > // Create a method instance > PostMethod postmethod = new PostMethod(url); > > // Assign parameters into post method > Iterator it = paramList.keySet().iterator(); > while (it.hasNext()) { > String paramName = (String) it.next(); > postmethod.addParameter(paramName, > new String(((String) paramList.get(paramName)).getBytes("UTF-8"),"UTF-8")); > } > > With the above codes I succeeded in sending out the postmethod with the list of parameters.

Therefore I switched to another method - to get the entire request body with input stream and added the following codes: > > if (inXMLMessage == null) > inXMLMessage = getXMLMessageFromInputStream (request.getInputStream()); > > ...... > > public String getXMLMessageFromInputStream (InputStream requestIS) { > String XMLMessage = ""; > try { > InputStreamReader isr = new InputStreamReader(requestIS, "UTF-8"); > BufferedReader r = new BufferedReader(isr); > XMLMessage = r.readLine(); > XMLMessage = URLDecoder.decode(XMLMessage); > XMLMessage = XMLMessage.substring(11); > } catch (Exception ex) {...} > return XMLMessage; > } > > With the above I succeeded to get the parameter I want, i.e. an xml message, from the input stream, but the entire message are "escaped", that is space and tab become "+", "<" become "%3C", etc. Thaz why I need to use URLDecoder . But the worst part is that all chinese charaters become weird codes like 測試, which should be "æè" in traditional chinese. > > I am really at my wits end as to what is happening here.
