create pdf from binary data in java

Question

I'm getting this string from a web service. "JVBERi0xLjQKMyAwIG9iago8PC9UeXBlIC9QYWdlCi9QYXJlbnQgMSAwIFIKL1Jlc291cmNlcyAyIDAgUgovR3JvdXAgPDwvVHlwZSAvR3JvdXAgL1MgL1RyYW5zcGFyZW5jeSAvQ1MgL0RldmljZVJHQj4" It is supposed to be a pdf file, i tried this library pdfbox from apache, but it writes the content as a text inside the pdf. I've tried with ByteArrayInputStream but the pdf created is not valid, corrupted, this is some of the code i've wrote. ``` public void escribePdf(String texto, String rutaSalida) throws IOException{ byte[] biteToRead = texto.getBytes(); InputStream is = new ByteArrayInputStream(biteToRead ); DataOutputStream out = new DataOutputStream(new BufferedOutputStream(new FileOutputStream(new File(rutaSalida)))); int c; while((c = is.read()) != -1) { out.writeByte(c); } out.close(); is.close(); } ```

Accepted Answer

That is Base64 encoded (most probably UTF-8) data, you must decode it before using; such as:

```
import sun.misc.BASE64Decoder;
```

...

```
BASE64Decoder decoder = new BASE64Decoder();
byte[] decodedBytes = decoder.decodeBuffer(biteToRead);
```

....

Edit: For java >= 1.8, use:

```
byte[] decodedBytes = java.util.Base64.getDecoder().decode(biteToRead);
```
