When migrating using BaseJavaMigration
You need to parse the json string and get the value
For this I use GSON
private String getArtifactVersion(InputStream inputStream) {
String jsonTemplate = "";
try {
StringWriter writer = new StringWriter();
IOUtils.copy(inputStream, writer, Charset.forName("UTF-8"));
jsonTemplate = writer.toString();
} catch (IOException ex) {
log.error("Error read file " + ex.getMessage(), ex);
}
String artifactVersion = "";
JsonObject jsonObject = new JsonParser().parse(jsonTemplate).getAsJsonObject();
JsonArray jsonArray = jsonObject.getAsJsonArray("Parameters");
for (int i = 0; i < jsonArray.size(); i++) {
JsonObject arrObject = jsonArray.get(i).getAsJsonObject();
log.info(arrObject.getAsString());
// if (arrObject.get.equals("ArtifactVersion")) {
// artifactVersion = arrObject.getString("Default");
// break;
// }
}
log.info(artifactVersion);
return artifactVersion;
}
But when I try to run the gradle flywayMigrate command, I get an error
Caused by: java.lang.NoClassDefFoundError: com/google/gson/JsonParser
How can I solve this problem?
Found a solution here.

I have written the RestClient to call the rest service and then parse the response. I use this:
HttpGet httpGet = new HttpGet(url);
HttpResponse httpResponse = httpClient.execute(httpGet);
HttpEntity httpEntity = httpResponse.getEntity();
is = httpEntity.getContent();
BufferedReader reader = new BufferedReader(new InputStreamReader(
is, "iso-8859-1"), 8);
StringBuilder sb = new StringBuilder();
String line = null;
while ((line = reader.readLine()) != null) {
sb.append(line + "\n");
}
is.close();
json = sb.toString();
} catch (Exception e) {
}
try {
jObj = new JSONObject(json);
} catch (JSONException e) {
}
jObj = new JSONObject(json);
return jObj;
I m getting response like this :
{\"r\":{\"#status\":\"ok\",\"#st\":\"ok\",\"#call_id\":\"8410e\",\"method\":\"notification\",\"notification\":" +

Could you please help me how i can parse it?
Thanks,

The code for converting to JSON is not exactly right - Try JSONObject. you can do better as shown below.
if (httpEntity != null) {
String resultString = EntityUtils.toString(httpEntity);
// parsing JSON and convert String to JSON Object
JSONObject result = new JSONObject(resultString);
return result;

What its wrong?
Applet is signed and compiled with java 1.6, httpclient-4.1.3.jar
For those with this problem, the solution was here http://hc.apache.org/httpcomponents-client-ga/tutorial/html/connmgmt.html#d5e571 getting the JRE Proxy.
DefaultHttpClient client = new DefaultHttpClient () ;
ProxySelectorRoutePlanner routePlanner = new ProxySelectorRoutePlanner(
client.getConnectionManager().getSchemeRegistry(),
ProxySelector.getDefault());
client.setRoutePlanner(routePlanner);
HttpResponse response = client.execute(requestBase) ;
Then i signed all libraries httpcore-4.2.3.jar, httpmime-4.2.3.jar and httpclient-4.2.3.jar.
I've been having some trouble connecting to a uri when I append a query string... I always get back 400 http code... however when I try the browser, same url, everything goes smooth...
This is what I have:
String query = "q=hello";
byte[] queryBytes = query.getBytes();
Somewhere in my code I open an HttpConnection using the queryBytes like this:
String uri = "https://www.google.co.ve/search" + "?" + new String(queryBytes);
HttpConnection request = (HttpConnection) Connector.open(uri);
request.getResponseCode();
If I don't use bytes for my connection everyting works fine:
String uri = "https://www.google.co.ve/search?q=hello";
Thanks in advance
When i try this, iam getting http code 200.
try {
String httpURL = "https://www.google.co.ve/search?q=hello";
HttpConnection httpConn;
httpConn = (HttpConnection) Connector.open(httpURL);
httpConn.setRequestMethod(HttpConnection.GET);
DataOutputStream _outStream = new DataOutputStream(httpConn.openDataOutputStream());
byte[] request_body = httpURL.getBytes();
for (int i = 0; i < request_body.length; i++) {
_outStream.writeByte(request_body[i]);
}
DataInputStream _inputStream = new DataInputStream(
httpConn.openInputStream());
StringBuffer _responseMessage = new StringBuffer();
int ch;
while ((ch = _inputStream.read()) != -1) {
_responseMessage.append((char) ch);
}
String res = (_responseMessage.toString());
String responce = res.trim();
httpConn.close();
Dialog.alert(responce);
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();

I have written one simple web service which get product list in JSONText which is string object
Web Service code is below
using System;
using System.Collections.Generic;
using System.Web;
using System.Web.Services;
using System.Web.Script.Services;
using System.Runtime.Serialization.Json;
using System.IO;
using System.Text;
/// <summary>
/// Summary description for JsonWebService
/// </summary>
[WebService(Namespace = "http://tempuri.org/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
[System.Web.Script.Services.ScriptService]
public class JsonWebService : System.Web.Services.WebService
{
public JsonWebService () {
//Uncomment the following line if using designed components
//InitializeComponent();
}
[WebMethod]
[ScriptMethod(ResponseFormat = ResponseFormat.Json)]
public string GetProductsJson(string prefix)
{
List<Product> products = new List<Product>();
if (prefix.Trim().Equals(string.Empty, StringComparison.OrdinalIgnoreCase))
{
products = ProductFacade.GetAllProducts();
}
else
{
products = ProductFacade.GetProducts(prefix);
}
//yourobject is your actula object (may be collection) you want to serialize to json
DataContractJsonSerializer serializer = new DataContractJsonSerializer(products.GetType());
//create a memory stream
MemoryStream ms = new MemoryStream();
//serialize the object to memory stream
serializer.WriteObject(ms, products);
//convert the serizlized object to string
string jsonString = Encoding.Default.GetString(ms.ToArray());
//close the memory stream
ms.Close();
return jsonString;
}
}
now it give me resoponse like below :
{"d":"[{\"ProductID\":1,\"ProductName\":\"Product 1\"},{\"ProductID\":2,\"ProductName\":\"Product 2\"},{\"ProductID\":3,\"ProductName\":\"Product 3\"},{\"ProductID\":4,\"ProductName\":\"Product 4\"},{\"ProductID\":5,\"ProductName\":\"Product 5\"},{\"ProductID\":6,\"ProductName\":\"Product 6\"},{\"ProductID\":7,\"ProductName\":\"Product 7\"},{\"ProductID\":8,\"ProductName\":\"Product 8\"},{\"ProductID\":9,\"ProductName\":\"Product 9\"},{\"ProductID\":10,\"ProductName\":\"Product 10\"}]"}
But i am looking for below out put
[{"ProductID":1,"ProductName":"Product 1"},{"ProductID":2,"ProductName":"Product 2"},{"ProductID":3,"ProductName":"Product 3"},{"ProductID":4,"ProductName":"Product 4"},{"ProductID":5,"ProductName":"Product 5"},{"ProductID":6,"ProductName":"Product 6"},{"ProductID":7,"ProductName":"Product 7"},{"ProductID":8,"ProductName":"Product 8"},{"ProductID":9,"ProductName":"Product 9"},{"ProductID":10,"ProductName":"Product 10"}]
can any one tell me what is actual problem
Thanks
First there was a change with ASP.NET 3.5 for security reasons Microsoft added the "d" to the response. Below is a link from Dave Ward at the Encosia that talks about what your seeing:
A breaking change between versions of ASP.NET AJAX. He has several posts that talks about this that can help you further with processing JSON and ASP.NET
Actually, if you just remove the
[ScriptMethod(ResponseFormat = ResponseFormat.Json)]
from the method, and you return the jsonString that you serialized using the JavaScriptSerializer you will get exactelly the output that you were looking for.
Notice that u have double quotes beside ur array in your response.In this way u return json format not json object from ur web method.Json format is a string.Therefore u have to use json.parse() function in order to parse json string to json object.If u dont want to use parse fuction,u have to remove serialize in ur web method.Thus u get a json object.

I made a Webservice Operation whose return type is STRING []
Following is the code
#WebMethod(operationName = "authorize")
public String [] authorize(#WebParam(name = "Username")
String Username) {
CAuthorization CA = new CAuthorization();
String [] Result= null;
try {
Result = CA.CheckAuthorization(Username);
} catch (SQLException ex) {
Logger.getLogger(WS_Authentication.class.getName()).log(Level.SEVERE, null, ex);
}
**return Result;**
}
And then i made a Servlet
The code of the servlet thing is :
try { // Call Web Service Operation
java.lang.String result = null;
result = port.authorize(Username);
out.println("Result = "+result);
} catch (Exception ex) {
// TODO handle custom exceptions here
}
Problem is in my WEbservice Code in RETURN STATEMENT i have attributes of any table
and i want to take these attributes to servlet so that i can see them on my front end
but what im getting here is the only the LAST ATTRIBUTE
Thanks!
This is the way u can handle Webservice Operation of String Return type
#WebMethod(operationName = "authorize")
public String authorize(#WebParam(name = "Username")
String Username) {
CAuthorization CA = new CAuthorization();
StringBuffer result = new StringBuffer();
try {
if (CA.CheckAuthorization(Username).length > 0) {
result.append(CA.CheckAuthorization(Username)[0]);
for (int i = 1; i < CA.CheckAuthorization(Username).length; i++) {
result.append(",");
result.append(CA.CheckAuthorization(Username)[i]);
}
}
} catch (SQLException ex) {
Logger.getLogger(WS_Authentication.class.getName()).log(Level.SEVERE, null, ex);
}
//TODO write your implementation code here:
return result.toString();
}
}
