System.exit()

Exit code is 0 when execution went fine; 1 , -1 , whatever != 0 when some error occurred, you can use different values for different kind of errors. If I'm correct exit codes used to be just positive numbers (I mean in UNIX) and according to range: 1-127 are user defined codes (so generated by calling exit(n) ) 128-255 are codes generated by termination due to different unix signals like SIGSEGV or SIGTERM The following codes are from http://www.opensource.apple.com/source/Libc/Libc-320/include/sysexits.h.

Using setInfoWindowStyle("MVInfoWindowStyle2",...) in Oracle Mapviewer, setInfoWindowTitle() is invalid.

There is an issue in oraclemaps.js of Oracle Fusion Middleware MapViewer Version 11g ps6 (11.1.1.7.1). When the value of the parameter style is "MVInfoWindowStyle2" in the function MVThemeBasedFOI.setInfoWindowStyle(style, styleParameters), the function MVThemeBasedFOI.setInfoWindowTitle does not work. So must re-write the part of oraclemaps.js, the codes are the following MVThemeBasedFOI.prototype.setInfoWindowTitle = function (x90) {     this._f320 = x90;     MVInfoWindowStyle2.Title=x90; } MVInfoWindowStyle2.addContent = function (x5) {     try{     if(this.Title!=undefined){      x5.childNodes[0].childNodes[0].childNodes[0].childNodes[0].childNodes[1].childNodes[0].childNodes[0].childNodes[0].innerHTML=this.Title;     }     }catch(e){       try{       x5.childNodes[0].childNodes[0].childNodes[0].childNodes[0].ch...
