POJava, iRpeort and JasperSoft - No report set for compiler: null
text
Body
copied!<p>I'm studying this heap of code a professor left for the class, a java program designed to tap into an Oracle Database, pull data, and compile them neatly into a report.</p> <p>I'm not too familiar with Java and reports (much more familiar with C# and Crystal Reports), hence, the studying, but according to my testing, several of the reports work fine. Three, however, seem dead-set on making my day that much less brighter.</p> <p>What's strange is that <em>all</em> the reports work fine while in the Eclipse environment. Once deployed using the installer, one gives off a curious error:</p> <p><strong>No report compiler set for language : null</strong></p> <p>I have no idea as to what causes this. Early attempts at consulting my friend Google led me to believe there's either a version incompatibility, or a missing jar file that wasn't included, or something equally hard to comprehend.</p> <p>The other two reports that work fine in the Eclipse environment and fail only on some deployment both give off a "AWT-EventQueue-0" AbstractMethodError, but since this doesn't always happen (as opposed to the former problem, which happens all the time), I'll tackle these issues one problem at a time, starting with the first.</p> <p>For reference, here's the stuff I <em>think</em> matters:</p> <ul> <li>jasperreports-3.5.2.jar, located in the <em>Referenced Libraries</em></li> <li>groovy-all.1.5.5.jar also located in the <em>Referenced Libraries</em></li> <li>jasperreports-3.0.0.jar, jasperreports-3.5.2.jar, and jasperreports-3.7.6.jar, located in <em>lib</em></li> <li>I believe the reports were created with iReport 3.0.0</li> </ul> <p>Project Structure: Project name is Goldilocks</p> <ul> <li>Goldilocks: <ul> <li>JRE System Library</li> <li>Referenced Libraries</li> <li>lib</li> <li>src (Folders with the .java files and classes inside them are inside this folder)</li> <li>reports <ul> <li>jasper (All the .jrxml and .jasper files are inside this folder)</li> </ul></li> </ul></li> </ul> <p>Operating System / Software Used:</p> <ul> <li>Windows 7 and Linux Ubuntu (dev system)</li> <li>Eclipse, Juno Release (dev Software; Since this program was made earlier and I'm just looking into it, actual dev software might be an earlier build, Ganymede iirc)</li> <li>Linux Ubuntu and Windows XP (target system)</li> </ul> <p>Can I have some help on what causes <strong>No report compiler set for language : null</strong> error? And how do I remedy this?</p> <p>Thanks.</p> <p>Regards, Zack_Falcon</p>
