title: Apache HttpClient POST Upload File won't work with MultipartEntityBuilder upload
body: <p>I have an HTML form that has a File Upload in it. I am trying to upload a Word doc through the form using <code>MultipartEntityBuilder</code>, but it is just not working.</p>
  
  <p>The form has several text inputs and 2 File Upload lines in it. If I use the <code>BasicNameValuePair</code> approach and just set those fields as empty Strings, the text fields are submitted correctly. Since I need to upload the files, I changed to <code>MultipartEntityBuilder</code> and can't even get the basic test working again.</p>
  
  <p><strong>The Working Code</strong></p>
  
  <pre><code>HttpClient client = HttpClientBuilder.create().build();
  String uploadUrl = "http://somepage.com/upload";
  
  HttpPost httppost = new HttpPost(uploadUrl);
  
  httppost.setHeader("Accept", "text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8");
  httppost.setHeader("Content-Type", "multipart/form-data");
  httppost.setHeader("Accept-Encoding", "gzip, deflate");
  
  List&lt;NameValuePair&gt; formparams = new ArrayList&lt;NameValuePair&gt;();
  
  formparams.add(new BasicNameValuePair("testField1", "Value1"));
  formparams.add(new BasicNameValuePair("testField2", "Value2"));
  formparams.add(new BasicNameValuePair("fileField1", ""));
  formparams.add(new BasicNameValuePair("fileField2", ""));
  
  httppost.setEntity(new UrlEncodedFormEntity(formparams, Consts.UTF_8));
  
  HttpResponse response = client.execute(httppost, httpContext);
  </code></pre>
  
  <p><strong>Trying MultipartEntityBuilder</strong></p>
  
  <pre><code>// Everything up to and including the Headers remain the same
  
  MultipartEntityBuilder builder = MultipartEntityBuilder.create();
  builder.setMode(HttpMultipartMode.BROWSER_COMPATIBLE);
  
  StringBody sb = new StringBody("Value1", ContentType.TEXT_PLAIN);
  builder.addPart("textField1", sb);
  
  sb = new StringBody("Value2", ContentType.TEXT_PLAIN);
  builder.addPart("textField2", sb);
  
  FileBody fb = new FileBody(new File("path to file"), ContentType.DEFAULT_BINARY);
  builder.addPart("fileField1", fb);
  
  fb = new FileBody(new Field("path to file2"), ContentType.DEFAULT_BINARY);
  builder.addPart("fileField2", fb);
  
  httppost.setEntity(builder.build());
  
  HttpResponse response = client.execute(httppost, httpContext);
  </code></pre>
  
  <p>The form is hosted by Oracle and get back the error:</p>
  
  <blockquote>
    <p>An unexpected error occurred: ORA-06501: PL/SQL: program error</p>
  </blockquote>
  
  <p>I have also tried these other approaches:</p>
  
  <pre><code>builder.addTextBody("textField1", "Value1");
  builder.addTextBody("textField2", "Value2");
  
  File file1 = new File("path to file1");
  builder.addBinaryBody("fileField1", file1, ContentType.DEFAULT_BINARY, file1.getName());
  
  File file2 = new File("path to file2");
  builder.addBinaryBody("fileField2", file2, ContentType.DEFAULT_BINARY, file2.getName());
  </code></pre>
  
  <p>As well as trying to mimic my first test by putting everything in the <code>builder.addTextBody()</code> like my original working test, but still get the same result.</p>
  
  <p><strong>Logging</strong></p>
  
  <p>As per @oleg request, I have posted the wire log from this call:</p>
