I am creating images using the following code..However, my app will stop after printing out STATEMENT 3 which means I can't use Image image = Image.createImage(input);

Is there anyway I can ctach this type of excpetion beside IOexception and Exception?
Does anyone have any idea? Thank in advance.

FileConnection filenames = (FileConnection)Connector.open(main_directory +  "testFolder" + "/"
                                                + imageName ,Connector.READ);
InputStream input = filenames.openInputStream();
try {
                                                Logger.logEventInfo("STATEMENT 3");
                                                Image image = Image.createImage(input);
                                                Logger.logEventInfo("READING: " + imageName +"\n");
                                                Logger.logEventInfo("STATEMENT 4");
                                                if(image != null){               
                                                      Logger.logEventInfo("STATEMENT 5");                                                
                                                }
                                                else continue;                                      
                                                Logger.logEventInfo("STATEMENT 7");
                                          }
                                          catch (IOException e) {
                                                Logger.logEventInfo("STATEMENT 8");                                                
                                                description = e.toString();
                                                Logger.logEventInfo("STATEMENT 9");
                                                Logger.logEventInfo("READING: " + imageName +"\n");
                                          } catch (Exception e)  {
                                                Logger.logEventInfo("STATEMENT 11");
                                                Exceptiondescription = e.toString();
                                                Logger.logEventInfo("STATEMENT 12");                                                
                                                updateContent("READING: " + imageName);      
                                                Logger.logEventInfo("READING: " + imageName +"\n");
                                                Logger.logEventInfo("STATEMENT 13");
                                          }                              
                                          Logger.logEventInfo("STATEMENT 14");
                                          input.close();

Can you show the code you use to get and configure the logger?  That might provide some insight into why it is throwing an error to begin with.

I am not sure if it's about the logger cause some of other images are able to pass STATEMENT 3 and goes into either createimage or Exception. However, for some image, it was unable to go anywhere

Exception is the mother of all java exceptions, so it should be catching any and all runtime exceptions this code throws.  However, Image.createImage also throws a NullPointerException - try catching that, and if it works, it probably means there is a scope issue with your image location.
