A site I found in French () suggested that there may be a problem with the syntax of an associated. The NetBeans Bugzilla site has bug reports of this problem but no information on how to fix it. Then I navigated to my project, and got the same results as before. It came up as if it were the first time I'd ever run it and asked me to register, as expected (I said "Never register" because I'm not connected to the internet anyway). To try to remedy this, I deleted my entire ~/.netbeans directory and restarted NetBeans. More details on that NullPointerException below this is occurring on a system that is not connected to the internet so I am hand-typing in the first several lines because I can't provide the NetBeans. I get very limited syntax highlighting (keywords in blue, string literals in orange, but nothing else), and none of the NetBeans niceties such code completion, ctrl-click navigation, and fixing imports. I'm on Red Hat 5.7 coding in Java with Spring and NetBeans RCP.Įvery time I open a file, or when I initially open NetBeans and it auto-opens the files I was working on last time, I get a NullPointerException and a message saying that "An error occurred during parsing of (filename)". Hope this has helped.I'm having a problem with NetBeans 6.9.1 that has cropped up recently after many months of problem-free use. This additional information will help me answer the question in specific details. Is the project free form project created from existing source?.Is the project Ant based or Maven based?.Is the project created from NetBeans New Project wizard?.Specify the main class through Menu option as follows: File > Project Properties > Run (Category) > Main Class (textbox) (If the project was created through NetBeans project wizard then this class is already defined, otherwise we have to do that manually) The manifest.mf file is available from the Files panel in the project root directory.įor making the JAR executable with the java -jar command you shall specify the Main class in the project configuration. If you have any custom requirement you can even modify the manifest.mf file which gets included in the built JAR. ![]() Ideally the classpath of the Jar file shall not contain root folder of the project, NetBeans adds library JARS if you have added them to the project in the Class-Path property in the manifest.mf file automatically. NetBeans creates a self sufficient JAR file for your project when you execute the "Clean and Build" command from Menu or Tool Button. You build section would be similar to this: You have to add two plugins ( maven-assembly-plugin and maven-jar-plugin) to the build section of your pom.xml file. I solved following this post in an external blog: I mannually changed the package name from inside my classes from myPackage to mypackage, and corrected all the imports (which were importing myPackage). I looked into the classes and the refactoring completely meshed up everything. Today I noticed that the class was reported as my Package/model instead of my package/model. The program executed fine inside the IDE and no errors were reported (although all the classes were declaring as belonging to my Package and in the tree they were under my package), but when I tried to run the jar inside the dist directory I got a class not found exception. It indeed changed the name of the package to mypackage as seen in the tree navigator, but the package name inside the file remained as myPackage. I had done refactoring and changed the package names from myPackage.model to mypackage.model. But why doesn't NetBeans add these in the classpath of the jar's manifest.I do not understand I added them manually, and re-created the jar from command line. UPDATE: In the dist/myJar, I extracted the jar, and in the manifest, the current path and the root path of my project were missing. Is there something equivalent in NetBeans? In eclipse I do a "create runnable jar", and the jar runs without issues. What am I doing wrong? Should I be using Ant or something (don't know Ant) But when I try to run the jar, that NetBeans has automatically created under the dist directory, I get a NoClassDefFoundErrorįor classes inside my project.
