显示的图像是我使用Swing
.
当我单击按钮时如何创建一个警报窗口Submit
并且警报应该显示直到执行的操作完成(警报+代码应该在后台运行)?
这是我的代码片段:
private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {
//alert window should start here when button performed
//and end based on the output i get
DefaultHttpClient httpclient = new DefaultHttpClient();
jLabel3.setText("");
try {
httpclient.getCredentialsProvider().setCredentials(
new AuthScope(getHost(), AuthScope.ANY_PORT),
new UsernamePasswordCredentials(getUser(), getPass()));
HttpResponse response = null;
HttpEntity entity = null;
try {
response = httpclient.execute(httpget);
if(response.getStatusLine().getStatusCode()==500) {
jLabel3.setText("Such Goods Movement does not exist / You do not have permssions for the entered.");
//end here or
} else if(response.getStatusLine().getStatusCode()==401) {
System.out.println(response);
jLabel3.setText("Auth Failed");
//end here or soon based on the event
}
entity = response.getEntity();
System.out.println(entity);
if (entity != null) {
InputStream instream = entity.getContent();
System.out.println(instream);
BufferedReader reader = new BufferedReader(
new InputStreamReader(instream));
String inputLine;
String xmlText="";
while ((inputLine = reader.readLine()) != null)
xmlText = xmlText+inputLine+"\n";
System.out.println(xmlText);
try {
DocumentBuilder db = DocumentBuilderFactory.newInstance().newDocumentBuilder();
InputSource is = new InputSource();
is.setCharacterStream(new StringReader(xmlText));
DefaultTableModel model = (DefaultTableModel) jTable1.getModel();
model.setRowCount(0);
Document doc = db.parse(is);
NodeList nodes = doc.getElementsByTagName("MaterialMgmtInternalMovementLine");
for (int i = 0; i < nodes.getLength(); i++) {
Element element = (Element) nodes.item(i);
getListGRNLine(element);
}
} catch (SAXException ex) {
Logger.getLogger(GoodsReceipt.class.getName()).log(Level.SEVERE, null, ex);
} catch (ParserConfigurationException ex) {
Logger.getLogger(GoodsReceipt.class.getName()).log(Level.SEVERE, null, ex);
}
}
} catch(UnknownHostException e){
jLabel3.setText("URL Not Found / Check Internet Connectivity");
} catch(NoRouteToHostException f){
jLabel3.setText("URL Not Found / Check Internet Connectivity");
} catch (IOException ex) {
Logger.getLogger(GoodsReceipt.class.getName()).log(Level.SEVERE, null, ex);
}
try {
EntityUtils.consume(entity);
} catch (IOException ex) {
Logger.getLogger(GoodsReceipt.class.getName()).log(Level.SEVERE, null, ex);
}
} catch (UnsupportedEncodingException ex) {
Logger.getLogger(GoodsReceipt.class.getName()).log(Level.SEVERE, null, ex);
} finally {
// When HttpClient instance is no longer needed,
// shut down the connection manager to ensure
// immediate deallocation of all system resources
httpclient.getConnectionManager().shutdown();
}
}
