I'm beginner in Java. Can you tell me please why the following code detected an error though I take exactly the same code given as an example in the following URL of google:
https://developers.google.com/bigquery/streaming-data-into-bigquery#streaminginsertexamples
the word bigquery is underlying in red and the error is: bigquery cannot be resolved.
I remember that I want to stream my data into BigQuery one record at a time by using the tabledata().insertAll() method.
This is my code:
import java.io.IOException;
import java.util.*;
import com.google.api.services.bigquery.*;
import com.google.api.services.bigquery.model.*;
public class sdz1 {
public static void main(String[] args) {
TableRow row = new TableRow();
row.set("Average", 7.7);
TableDataInsertAllRequest.Rows rows = new TableDataInsertAllRequest.Rows();
rows.setInsertId(""+System.currentTimeMillis());
rows.setJson(row);
List rowList = new ArrayList();
rowList.add(rows);
TableDataInsertAllRequest content = new TableDataInsertAllRequest().setRows(rowList);
try
{
TableDataInsertAllResponse response = bigquery
.tabledata()
.insertAll("Vigicolis", "wi_vigicolis", "TestTable", content)
.execute();
// TableDataInsertAllResponse response = new TableDataInsertAllResponse();
// response.bigquery.tabledata().insertAll("Vigicolis", "wi_vigicolis", "TestTable", content).execute();
System.out.println("Response: " + response);
}
catch (IOException e)
{
// handle
}
}
}
You are missing jar file of BigQuery which provides the required packages and classes required to run this program. Find the jar and add it to your classpath via command or in IDE.
Maven dependency link for the jar and jar can be downloaded as well from this link.
You need to create the bigquery object.
Ex:
Bigquery bigquery = new Bigquery(new NetHttpTransport(), new JacksonFactory(), new AppIdentityCredential(SQLSERVICE_ADMIN));

Im using #lgoncalves code to sign an XML with XADES4J EPES. But however jdeveloper don't find (SignerEPES) when I have the xades4j.jar on my classpath. I let you the image of my library and the code:
Project Library
private static void signBes(Document doc) throws XadesProfileResolutionException, XAdES4jException,
KeyStoreException {
//Document doc = getTestDocument();
Element elemToSign = doc.getDocumentElement();
SignaturePolicyInfoProvider policyInfoProvider = new SignaturePolicyInfoProvider()
{
#Override
public SignaturePolicyBase getSignaturePolicy()
{
return new SignaturePolicyIdentifierProperty(
new ObjectIdentifier("oid:/1.2.4.0.9.4.5", IdentifierType.OIDAsURI, "Policy description"),
new ByteArrayInputStream("Test policy input stream".getBytes()))
.withLocationUrl(""); //<- I really don't know what to put right here.
}
};
KeyingDataProvider kdp = new FileSystemKeyStoreKeyingDataProvider("pkcs12","C:/****/****.pfx",new FirstCertificateSelector(),new DirectPasswordProvider("****"),new DirectPasswordProvider("****"),true);
SignerEPES signer = (SignerEPES) new XadesEpesSigningProfile(kdp, policyInfoProvider).newSigner();
new Enveloped(signer).sign(elemToSign);
}
Link to the sample code on GitHub: https://github.com/luisgoncalves/xades4j/blob/master/src/test/java/xades4j/production/SignerEPESTest.java
EDIT:
I tried to force the import like (import xades4j.production.SignerEPES) but IDE says "Cannot be accessed from outside package" but really don't know what that means
SignerEPES is a package-private class, so application code won't be able to import it. The tests use it just to be sure that the proper type is being returned.
In your code you can just use XadesSigner as the type of your variable.
I want to attach multiple files to issue. I'm able to create issue successfully however i am facing problem in attaching documents after creating issue. I have referred to this link SOLVED: attach a file using REST from scriptrunner
I am getting 404 error even though issue exists and also user has all the permissions.
File fileToUpload = new File("D:\\dummy.txt");
InputStream in = null;
try {
in = new FileInputStream(fileToUpload);
} catch (FileNotFoundException e) {
e.printStackTrace();
}
HttpResponse < String > response3 = Unirest
.post("https://.../rest/api/2/issue/test-85/attachments")
.basicAuth(username, password).field("file", in , "dummy.txt")
.asString();
System.out.println(response3.getStatus());
here test-85 is a issueKey value.
And i am using open-unirest-java-3.3.06.jar. Is the way i am attaching documents is correct?
I am not sure how open-unirest manages its fields, maybe it tries to put them as json field, rather than post content.
I've been using Rcarz's Jira client. It's a little bit outdated but it still works.
Maybe looking at its code will help you, or you can just use it directly.
The Issue class:
public JSON addAttachment(File file) throws JiraException {
try {
return restclient.post(getRestUri(key) + "/attachments", file);
} catch (Exception ex) {
throw new JiraException("Failed add attachment to issue " + key, ex);
}
}
And in RestClient class:
import org.apache.http.client.methods.HttpEntityEnclosingRequestBase;
import org.apache.http.entity.mime.MultipartEntity;
import org.apache.http.entity.mime.content.FileBody;
public JSON post(String path, File file) throws RestException, IOException, URISyntaxException {
return request(new HttpPost(buildURI(path)), file);
}
private JSON request(HttpEntityEnclosingRequestBase req, File file) throws RestException, IOException {
if (file != null) {
File fileUpload = file;
req.setHeader("X-Atlassian-Token", "nocheck");
MultipartEntity ent = new MultipartEntity();
ent.addPart("file", new FileBody(fileUpload));
req.setEntity(ent);
}
return request(req);
}
So I'm not sure why you're getting a 404, Jira is sometime fuzzy and not really clear about its error, try printing the full error, or checking Jira's log if you can. Maybe it's just the "X-Atlassian-Token", "nocheck", try adding it.
I have a requirement of uploading images to cloudinary using cloudinary's java API.I have created cloudinary account through which i got api Cloud name,API Key,API Secret. Using these things i am able to upload my images to cloudinary like bellow:
#PostMapping("/uploadPic")
public ResponseEntity<Object> upload(#RequestParam("file") MultipartFile multipartFile){
String cloudinaryImgURL=null;
try {
File fileDir = new File("rowFiles");
if (! fileDir.exists()){
fileDir.mkdir();
}
String fileName=multipartFile.getOriginalFilename();
File physicalFile=new File(multipartFile.getOriginalFilename());
FileOutputStream fout=new FileOutputStream(fileDir.getName()+"/"+physicalFile);
fout.write(multipartFile.getBytes());
fout.close();
//For stack-overflow question using dummy values for credientials.
Cloudinary cloudinary = new Cloudinary(ObjectUtils.asMap(
"cloud_name", "your_cloud_name",
"api_key", "your_api_key",
"api_secret", "your_secret_key"));
File toUpload = new File("rowFiles/"+fileName);
Map params = ObjectUtils.asMap("public_id", "SRWRestImageBase/"+fileName);
Map uploadResult =Singleton.getCloudinary().uploader().upload(toUpload, params);
toUpload.delete();
System.out.println("==============>>"+uploadResult.get("url"));
cloudinaryImgURL=uploadResult.get("url").toString();
} catch (Exception e) {
System.out.println("upload:"+e.getMessage());
// TODO: handle exception
}
return new ResponseEntity<Object>("File uploaded successfully:"+cloudinaryImgURL,HttpStatus.OK);
}
But now my problem is that i keep this code in public git repo, and from there i push this code to Heroku. But using this method will expose my cloudinary details like Cloud name,API Key,API Secret to everyone which i don't want.
Looking at cloudinary's documentation for getting started i found the way of using environment variable to store these values and access it from there, but document doesn't guide me properly.
I have used
In a Java EE environment you can set an environment variable available to your Java EE container:
CLOUDINARY_URL=cloudinary://{api_key}:{api_secret}#{cloud_name}
This will enable you to receive a Cloudinary instance:
Cloudinary cloudinary = Singleton.getCloudinary();
But i am getting compile-time error for class Singleton that it is not able to find in any jar. Looking at some other article, this class should com.cloudinary.Singleton, but my cloudinary jar does not have this class.
I am using cloudinary gradle dependancy as:
// https://mvnrepository.com/artifact/com.cloudinary/cloudinary-http43
compile group: 'com.cloudinary', name: 'cloudinary-http43', version: '1.2.2'
It would be appreciated if someone can guide me in right direction.
Thanks in Advance.
I have found my own solution.
We have to set environment variable CLOUDINARY_URL=cloudinary://{api_key}:{api_secret}#{cloud_name} and restart eclipse to reflect the environment variable changes and following changes. This way it wont expose my account details to public repo.
#PostMapping("/uploadPic")
public ResponseEntity<Object> upload(#RequestParam("file") MultipartFile multipartFile){
String cloudinaryImgURL=null;
try {
File fileDir = new File("rowFiles");
if (! fileDir.exists()){
fileDir.mkdir();
}
String fileName=multipartFile.getOriginalFilename();
File physicalFile=new File(multipartFile.getOriginalFilename());
FileOutputStream fout=new FileOutputStream(fileDir.getName()+"/"+physicalFile);
fout.write(multipartFile.getBytes());
fout.close();
File toUpload = new File("rowFiles/"+fileName);
Cloudinary cloudinary = new Cloudinary();
System.out.println("API Key:"+cloudinary.config.apiKey);
Map params = ObjectUtils.asMap("public_id", "SRWRestImageBase/"+fileName);
Map uploadResult = cloudinary.uploader().upload(toUpload, params);
toUpload.delete();
System.out.println("==============>>"+uploadResult.get("url"));
cloudinaryImgURL=uploadResult.get("url").toString();
} catch (Exception e) {
System.out.println("upload:"+e.getMessage());
}
return new ResponseEntity<Object>("File uploaded successfully:"+cloudinaryImgURL,HttpStatus.OK);
}
I've tried this code and added the needed jar files but still I'm getting an error message like Exception in thread "main" java.lang.UnsatisfiedLinkError: Unable to load library 'libtesseract302'.
Is there a complete tutorial how to extract text and what things should be done to address the error? Any help is appreciated...
import net.sourceforge.tess4j.*;
import java.io.File;
public class ExtractTxtFromImg {
public static void main(String[] args) {
File imgFile = new File("C:\\Documents and Settings\\rueca\\Desktop\\sampleImg.jpg");
Tesseract instance = Tesseract.getInstance(); // JNA Interface Mapping
// Tesseract1 instance = new Tesseract1(); // JNA Direct Mapping
try {
String result = instance.doOCR(imgFile);
System.out.println(result);
} catch (Exception e) {
System.err.println(e.getMessage());
}
}
}
In addition to adding the jars, you also need to add the natives. You can do so with Djava.library.path="C:\[absolute path to dir containing *.dll files and such]"
Note that you need to provide the directory, not the file itself.
I have saved a file into mongoDB using gridFS like so.
Mongo mongo = new Mongo("XXXXX", XXXX);
DB db = mongo.getDB("XXX");
GridFS fs = new GridFS(XXX);
File install = new File("C:\\Users\\Nabeel\\Desktop\\docs.txt");
GridFSInputFile inFile = fs.createFile(install);
inFile.save();
Now I want download that file using spring MVC. I don't seep to able to find example on how i can get the file back as gridFS has converted the file into binary.
An example code would be nice as i am new to all this.
Thanks you in advance
You can do something like this for serving file :
public void downloadFile(String videoId , HttpServletResponse response ) {
InputStream is = null;
ApplicationContext ctx = new AnnotationConfigApplicationContext(MongoDBConfiguration.class);
GridFsOperations gridOperations = (GridFsOperations) ctx.getBean("YourBeanName");
List<GridFSDBFile> result = gridOperations.find(new Query().addCriteria(Criteria.where("_id").is(videoId)));
for (GridFSDBFile file : result) {
try {
/* send file */
} catch (Exception e) {
response.setStatus(HttpStatus.INTERNAL_SERVER_ERROR.value());
}
}
}
Send file example here: How do I return a video with Spring MVC so that it can be navigated using the html5 <video> tag?
This link about video serving but it can give you an idea. Use method 2 in the link and GridFSDBFile's getInputStream() method.
