    <p>Trying to download file with apache httpclient library and have a problem with resulting file being smaller than the original (approximately 32-32kb, when normal file size is 92-93) and cannot be opened normally in pdf viewer. Can someone explain me why this can be happening ? (Using firefox to download this file can sometimes lead to file being downloaded fully and sometimes being downloaded partly) </p> <p>Here is code I was using to download file via URL</p> <pre><code> URL url = new URL("pathtofile"); final URLConnection connection = url.openConnection(); final InputStream is = connection.getInputStream(); FileOutputStream fos = new FileOutputStream("C://result1.pdf"); byte buffer[] = new byte[1024]; int bytesRead; while ((bytesRead = is.read(buffer)) &gt;= 0) { fos.write(buffer, 0, bytesRead); } fos.flush(); fos.close(); is.close(); </code></pre> <p>P.S. Was trying to download this file using HttpClient apache library, same result.</p> <p>UPDATED: Monitoring traffic with network tool I found the difference between receiving file via Firefox and application. </p> <p>With Firefox first HttpPayloadLine was :</p> <p><code>HTTPPayloadLine: 83 Td /F2 5.80476 Tf (A:\040Asinis\04017.12.10\04008:32\040laboratorij) Tj 100 Tz 1 1 1 rg /F1 5.80476 Tf 0 0 0 rg 104.4856 0 Td &lt;0145&gt; Tj 1 1 1 rg 0 0 0 rg 3.62799 0.72565 Td /F2 5.80476 Tf (\040) Tj 1 1 1 rg 0.83137 0.81569 0.78431 RG ET 51</code></p> <p>With application first HttpPayload was </p> <p><code>HTTPPayloadLine: CWgC,ú&amp;ÿ3@Î"ݯV¨®~×&gt;×)\ªleÚl</code>µï½ci ¤Ãðð'È/CÈAø¯ª Í<code>übA«1Ãÿ Åç«VɬZòYóóy7»ÇH.o²e&lt;qZna3l±°¥þ6ñþ[2YÚ1ì³Eë-ÓÊÏ$y:tÎà![ËÅS¤¿É¡¢è,þ|ºs¨)@¢Qâ¯ÝF~}oµÒ&gt;¦ OAxz³äÒ.ß9 æÃZ¤ùÒ¨*«øUή+4×</code></p> <p>This measurements was taken via Microsoft Network Monitor</p> <p><strong>LAST UPDATE</strong> It was a server problem after all, after they fixed that files are downloaded successful</p>

    1. COIf you read the URL connection input stream you will read "everything" that comes from server. If "pathtofile" is a http request the servers output will include some header information that cannot be processed by the pdf viewer. What is the contents of the file that is downloaded so far ? It is starting with "%PDF" ?

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.
