    <p>I am trying to upload a log file from an applet. The applet uploads a file to a web application (environment Struts 2, Jboss) and receives response (string) from the server</p> <p>I am using following code to connect, upload a (log) file and receive server response from a application hosted on localhost on Jboss, running at port 8080 :</p> <pre><code>byte[] myData = aData.getBytes(); /* Uploading the data */ URL myURL = new URL(aURL); URLConnection myConnection = myURL.openConnection(); myConnection.setDoOutput(true); myConnection.setUseCaches(false); myConnection.setDefaultUseCaches(false); myConnection.setRequestProperty("Content-type", "application/octet-stream"); OutputStream myOutputStream = myConnection.getOutputStream(); myOutputStream.write(myData); myOutputStream.flush(); myOutputStream.close(); /* Getting the response */ InputStream myInputStream = myConnection.getInputStream(); byte myBytes[] = new byte[1024]; StringBuffer myStringBuilder = new StringBuffer(); int myReadCount = myInputStream.read(myBytes); while (myReadCount &gt; 0) { myStringBuilder.append(new String(myBytes, 0, myReadCount)); myReadCount = myInputStream.read(myBytes); } return myStringBuilder.toString(); </code></pre> <p>On server side, Struts 2 is being used and and action is called to receive this file. The Following code is called at server side :</p> <pre><code>InputStream inputStream = request.getInputStream(); byte[] appletLog = UploadUtil.readFromInputStream(inputStream); //appletLog saved in db here; return UPLOAD_RESPONSE_SUCCESS; </code></pre> <p>Please note that the server side code executes fine, without any exception etc and file is saved in database successfully.</p> <p>But right after that a <strong>java.io.FileNotFoundException:</strong> is thrown at line <strong>[EDIT]</strong> <code>InputStream myInputStream = myConnection.getInputStream();</code>. I could not find the reason. I would really appreciate if someone can point out mistakes and provide Hints.</p>

    1. COAs you said you use Struts2, let me know what does the result UPLOAD_RESPONSE_SUCCESS point to. Is it a page response?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
