    <p>I'm debugging J2ME (written in eclipse) code on nokia N95 (wasn't written by me) trying to find error and printing out stacktrace gave me this:</p> <pre><code> 03:08:479 TSKR. Error: java.lang.NullPointerException: 0 - java.lang.String.&lt;init&gt;(), bci=6 - v.b(), bci=9 - v.e(), bci=805 - v.e(), bci=3 </code></pre> <p>Could anyone please help me to understand that? Which line , where to look for and is there a way to understand it or at least get some valuable and usefull information. Thank you</p> <p>UPDATE</p> <p>Sorry.. Here's the function that throws error:</p> <pre><code>public void bluetoothFileProcessBytes(){//--------tracing out of memory error try{ partCurrentLoop++; fileCurrentLoop++; debug("Loop " + fileCurrentLoop + " of " + fileTotalLoops); bluetoothUpdateBytes(fileDataString.length()); guiUpdateProgressBar(true, partCurrentLoop, partTotalLoops); // LOOP Step 2: If there is no byte[] created for storing the bytes, create it. if (fileBytesIsEmpty) { if (partCurrentNumber == partTotalNumber) { fileBytes = new byte[fileSize % (loopsPerHttpComm * BYTES_PER_LOOP)]; } else fileBytes = new byte[loopsPerHttpComm * BYTES_PER_LOOP]; } fileBytesIsEmpty = false; //LOOP Step 3: fill in the byte array with data from StringBuffer for (int i = 0; i &lt; fileDataString.length(); i++) { j = i + (partCurrentLoop - 1) * BYTES_PER_LOOP; c = fileDataString.charAt(i); fileBytes[j] = (byte) c; } c=0; j=0; i=0; //LOOP Step 4: Send the email if the byte array is full with a new HttpComm Thread if ((fileCurrentLoop % loopsPerHttpComm == 0 || fileCurrentLoop == fileTotalLoops) &amp;&amp; checkHttpCommStatus()) { // update partName and httpCommStatus String partName = fileName + " .part " + partCurrentNumber; httpCommStatus = HTTP_RUNNING; if (fileCurrentLoop == fileTotalLoops) { // FILE_END debug("New HttpComm Thread: FILE END"); httpCommUpdateBytes(fileBytes.length);//&lt;===================remove httpCommSucceeded();//&lt;====================================remove /*new Thread(new HttpFileEnd(this, fileBytes, toAddress, fromAddress, fromName, digidownMAC, partName, fileName, fileSize, digidownSoftwareVersion, partCurrentNumber, //&lt;===============uncomment partTotalNumber, DigidownApp.textObject.getActiveLanguage())).start();*/ } else { // FILE_PART //debug("Step 5");//&lt;--------------------------------------------------------------------------------&lt;-remove debug("New HttpComm Thread: FILE PART: " + partName); debug("&gt;&gt;&gt;&gt;&gt;SEEEENDIIIING!&lt;&lt;&lt;&lt;&lt;&lt;&lt;&lt;");//&lt;===========remove httpCommUpdateBytes(fileBytes.length);//&lt;================remove httpCommSucceeded();//&lt;==============================remove /*new Thread(new HttpFilePart(this, fileBytes, toAddress, fromAddress, fromName,//&lt;===============uncomment digidownMAC, partName, fileSize, digidownSoftwareVersion, partCurrentNumber, DigidownApp.textObject.getActiveLanguage())).start();*/ // Updating the new partTotalLoops if (partCurrentNumber == partTotalNumber){ partTotalLoops = fileTotalLoops - (loopsPerHttpComm * (partCurrentNumber - 1)); } else partTotalLoops = loopsPerHttpComm; partCurrentNumber++; partCurrentLoop = 0; } fileBytesIsEmpty = true; } // Leave the loop if failed if (!errorHandlerActivated) { if (fileCurrentLoop &lt; fileTotalLoops) { try{ bluetoothIOStream.getFileBytes();//-throws null pointer exception ! }catch(RuntimeException ea){debug("Wammaaa!!!

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
