Custom jar not producing output

[NM]

Hi Team,

I have created a custom jar .. followed the document steps added it in under "External Jar" section

created a "invoke jar job. Currently as a test i am just trying to get the access token from my saviynt environment (that is not the complete use case)

I code see below statement getting executed in logs but nothing else and also gives no error

obj.info("testworkjarexecute");

Code-

import java.util.Base64;

import java.io.BufferedReader;

import java.io.InputStreamReader;

import java.net.HttpURLConnection;

import java.net.URL;

import java.util.logging.*;

import java.io.OutputStream;

import java.nio.charset.StandardCharsets;

//import com.google.gson.JsonObject;

//import com.google.gson.Gson;

public class Classcall {

public static void main(String[] args) throws Exception {

String accessToken = "";

try {

Logger obj= Logger.getLogger(Classcall.class.getName());

URL url = new URL("URL");

HttpURLConnection conn = (HttpURLConnection) url.openConnection();

conn.setRequestMethod("POST");

conn.setRequestProperty("Content-Type", "application/json");

conn.setDoOutput(true);

obj.info("testworkjarexecute");

String requestBody = "{\"username\": \"username\", \"password\": \"password\"}";

byte[] input = requestBody.getBytes(StandardCharsets.UTF_8);

OutputStream os = conn.getOutputStream();

os.write(input, 0, input.length);

if (conn.getResponseCode() != 200) {

throw new RuntimeException("Failed : HTTP error code : " + conn.getResponseCode());

}

obj.info("--connresponsecode--"+conn.getResponseCode());

BufferedReader br = new BufferedReader(new InputStreamReader((conn.getInputStream())));

String output;

StringBuilder responseBuilder = new StringBuilder();

while ((output = br.readLine()) != null) {

responseBuilder.append(output);

}

br.close();

obj.info("executed till here");

obj.info("--Entering into main method of class ZipExtractor--"+responseBuilder.toString());

//accessToken = response.getAccessToken();

//System.out.println("token---------->" + accessToken);

conn.disconnect();

} catch (Exception e) {

e.printStackTrace();

}

}

}

FYI- I haven't added any saviynt certification in certificate management.

Could someone please help me out with this

Thanks

@rushikeshvartak , logs consist of only 3 lines 

Start externaljar job

Print statment testjarexecute

End job

That it..

[rushikeshvartak]

Try below code.

import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.net.HttpURLConnection;
import java.net.URL;
import java.util.logging.*;
import java.io.OutputStream;
import java.nio.charset.StandardCharsets;

public class Classcall {

    public static void main(String[] args) throws Exception {
        String accessToken = "";
        Logger obj = Logger.getLogger(Classcall.class.getName());

        try {
            URL url = new URL("URL");
            HttpURLConnection conn = (HttpURLConnection) url.openConnection();
            conn.setRequestMethod("POST");
            conn.setRequestProperty("Content-Type", "application/json");
            conn.setDoOutput(true);
            obj.info("Connection initialized");

            String requestBody = "{\"username\": \"username\", \"password\": \"password\"}";
            byte[] input = requestBody.getBytes(StandardCharsets.UTF_8);
            OutputStream os = conn.getOutputStream();
            os.write(input, 0, input.length);
            obj.info("Request body sent");

            if (conn.getResponseCode() != 200) {
                throw new RuntimeException("Failed : HTTP error code : " + conn.getResponseCode());
            }
            obj.info("HTTP response code: " + conn.getResponseCode());

            BufferedReader br = new BufferedReader(new InputStreamReader((conn.getInputStream())));
            String output;
            StringBuilder responseBuilder = new StringBuilder();

            while ((output = br.readLine()) != null) {
                responseBuilder.append(output);
            }
            br.close();
            obj.info("Response received and read");

            obj.info("Response: " + responseBuilder.toString());
            conn.disconnect();

        } catch (Exception e) {
            obj.log(Level.SEVERE, "Exception occurred", e);
        }
    }
}

@rushikeshvartak , thanks .. have done a restart will update you .. in another 15-20 mins.

2) while importing I am having error in moduleinfo.java file and not importing that.. as jar is getting executed and I can see some details in logs i believe it should be alright.

Hi @rushikeshvartak ,

Trying to fetch response data so i have used JSONObject class and obviously added dependency in pom.xml file, can't we add Maven project in Saviynt External jar.. if not what is the is an alternative way.

[rushikeshvartak]

• create simple java code instead of spring-based.
• dependency can be uploaded separately 

[NM]

@rushikeshvartak just to clarify if I need to use jsonobject class so you mean I can't use it or I need to download seperate dependency file club it into the executable Java file and make one jar file?

@rushikeshvartak , if you can please guide me .. your help us much appreciated 🙂

Update: if we upload the dependency file as in jsonobject class jar file seperately will it work??

[rushikeshvartak]

It will work

[NM]

@rushikeshvartak , sorry what will work didn't get you ?

[rushikeshvartak]

• Build your java code with Intellj and use logger which will also print logs

Hi @rushikeshvartak , let me try it.

Hello @NM ,
Try this :

Spoiler

public String getToken() {
String updateresponse = "";
try {
String tokengen="Bearer "+"<TOKENTOESTABLISHFIRSTCONNECTION>";
System.out.println("Got the token "+tokengen);
String URL ="<URL>/ECM/api/login";
URL updateurl= new URL(URL);
System.out.println(updateurl);
String readLine = null;
JSONObject serverDetailsObject = new JSONObject();
serverDetailsObject.put("username", "<username>");
serverDetailsObject.put("password", "<password>");
String jsonObjectString = serverDetailsObject.toString();
System.out.println("jsonObjectString ==> " + jsonObjectString);
HttpURLConnection conection = (HttpURLConnection) updateurl.openConnection();
conection.setDoInput(true); conection.setDoOutput(true);
conection.setRequestMethod("POST");
conection.setRequestProperty("Accept", "*/*");
conection.setRequestProperty("Content-Type", "application/json");
// String userName = "";
//String userCredentials =
//userName + ":" + userPassword;
// System.out.println(userName);
//LOGGER.info("Username ==> " + userName);
//System.out.println(userPassword); // LOGGER.info("UserPassowrd ==> " +
//userPassword); //String basicAuth = "Basic " +
//Base64.getEncoder().encodeToString(userCredentials.getBytes());

conection.setRequestProperty("Authorization", tokengen);
OutputStreamWriter outputStreamWriter = new OutputStreamWriter(conection.getOutputStream());
outputStreamWriter.write(jsonObjectString);
//System.out.println("outputStreamWriter ==> " + outputStreamWriter);
//LOGGER.info("outputStreamWriter ==> " + outputStreamWriter);
outputStreamWriter.flush();
System.out.println("Server object data ==> " + serverDetailsObject);
System.out.println("Connection\n" + conection + "\n");
int responseCode = conection.getResponseCode();
System.out.println("RESPONSE CODE = " + responseCode);
if (responseCode == HttpURLConnection.HTTP_OK) {
BufferedReader in = new BufferedReader(new
InputStreamReader(conection.getInputStream()));
StringBuffer response = new StringBuffer();
while ((readLine = in.readLine()) != null) {
response.append(readLine);
}
in.close();
updateresponse = response.toString();
JSONObject obj=new JSONObject(response.toString());

ftoken=obj.get("access_token");
System.out.println(ftoken); // }

} else {

System.out.println("POST NOT WORKED"); }

} catch (Exception e) {

updateresponse = e.getMessage(); e.printStackTrace();

} finally {


}

return ftoken.toString();

}

There is no certificate needed for this.
