Implement Restful web service client in Call Studio 10.5

[vincent.zheng]

The library I use is following:

http-client-4.5.10.jar
httpcore-4.4.12.jar
httpmime-4.5.10.jar

Here is my custom java code

package com.mycompany.cvp.webservice;

import java.io.File;

import org.apache.http.HttpEntity;
import org.apache.http.client.methods.CloseableHttpResponse;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.entity.ContentType;
import org.apache.http.entity.mime.MultipartEntityBuilder;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClients;
import org.apache.http.util.EntityUtils;

import com.audium.server.AudiumException;
import com.audium.server.action.context.ApplicationModifier;
import com.audium.server.session.ActionElementData;

public class ItspWebServiceClient extends ApplicationModifier {

    @Override
    public String getElementName() {
        return "RestWebServiceClient";
    }

    @Override
    public String getDisplayFolderName() {
        return "My Company Elements";
    }

    @Override
    public void doAction(String name, ActionElementData actionData) throws AudiumException {
        String urlLink = (String)actionData.getSessionData("SpeechURL");
        String filePath = actionData.getElementData("PolicyNumber", "filepath");
        String filename = actionData.getElementData("PolicyNumber", "filename");
        CloseableHttpClient client = HttpClients.createDefault();
        HttpPost httpPost = new HttpPost(urlLink + "/processFile");
        MultipartEntityBuilder builder = MultipartEntityBuilder.create();
        builder.addBinaryBody("file", new File(filePath), ContentType.APPLICATION_OCTET_STREAM, filename);
        HttpEntity multipart = builder.build();
        httpPost.setEntity(multipart);

        CloseableHttpResponse response;
        try {
            response = client.execute(httpPost);
            HttpEntity responseEntity = response.getEntity();
            String result = EntityUtils.toString(responseEntity);
            actionData.addToLog("SpeechRecognition", result);
            client.close();
            actionData.setSessionData("return", result);
        } catch (Exception e) {
            throw new AudiumException("Speech Recogniation exception");
        }
        super.doAction(name, actionData);
    }
}

The above code is taking the audio files and call the web service to recognize what user said, and based on the string that return back to perform following action.

However, when I deploy the whole project to VXMLServer, it complains following:

 In server side I already put all the jar file into common folder, what else I need to do?

[Quigath · Accepted solution]

What I do:

1. compile my code files with java 1.8.151
2. copy my java class files into /deploy/java/application/classes/[appName]/
3. copy my java jar files into /deploy/java/application/lib/
   1. this includes all jars my library jars/code depend on
4. Deploy project files out to the server
