Playframework 2.x Apache Tika issue

Question

i am uploading file using upload from then after getting uploaded file i am using Apache tika top extract content,metadata from uploaded file and applying but some error is coming

have a look of my playframework controller code :

public static Result upload() {
        MultipartFormData body = request().body().asMultipartFormData();
        FilePart picture = body.getFile("doc");
        if (picture != null) {

            String fileName = picture.getFilename();
            int eof = fileName.lastIndexOf('.');
            String ext = fileName.substring(eof + 1);

            file = picture.getFile();

            InputStream is;
            try {
                is = new FileInputStream(file);
            } catch (FileNotFoundException e) {

                e.printStackTrace();
            }
            Parser ps=new AutoDetectParser();

            BodyContentHandler bch=new BodyContentHandler();

            Metadata metadata=new Metadata();

            try {
                ps.parse(is, bch, metadata, new ParseContext());
            } catch (IOException | SAXException | TikaException e) {

                e.printStackTrace();
            }

            String sw=bch.toString();


            return ok(sw+" entity extracted and saved" + ext);
      }else {
        flash("error", "Missing file");
        return redirect(routes.Application.index());
    }

but when i am running this web application i am using commands :

rahul@inext:~/playframwrk apps/EntWebPrj$ play

[warn] play - No application found at invoker init

i added tika jar file.

Give me some idea to fix this issue.

Answer 1

Adding a dependency to Playframework can be done in two ways :

1. Unmanaged dependencies : directly add the jar in a /lib folder at the root of your project and restart your play application.

2. Managed dependencies : Add the jar to your build.sbt file as in the following example :

    val appDependencies = Seq( jdbc, cache, "org.apache.tika" % "tika" % "0.3" ) 

Answer 2

我认为您还需要添加tika-parsers-XYjar文件（其中XY是版本，例如1.4）。
