executable-jar

问题 I have an application that I deploy as an executable JAR file. Originally, this JAR file would communicate with a MySQL database but recently I have decided I want to go with SQLite instead. However, while testing I found that I could not access my SQLite database file when running my application from the JAR file. I'm using the JDBC driver from the following website: http://zentus.com/sqlitejdbc/index.html Is there a workaround I have to do? The driver works great while testing in my Eclipse

问题 I am building a JavaFX application through E(fx)clipse and Java Scene Builder . The basic functionality is a login window. Once logged in, new window opens and the login window disapears. Right now it's just at the prototype stage. When running out of ecplise, the functionality I want is all there. Login window shows up on start (code looking as such) @Override public void start(Stage primaryStage) { try { Parent root = FXMLLoader.load(getClass().getResource("view/login.fxml"), ResourceBundle

问题 I am try to make things works with tess4j (OCR algorithm), and i m using this code: import java.awt.image.RenderedImage; import java.io.File; import java.net.URL; import javax.imageio.ImageIO; import net.sourceforge.tess4j.*; public static void main(String[] args) throws Exception{ URL imageURL = new URL("http://s4.postimg.org/e75hcme9p/IMG_20130507_190237.jpg"); RenderedImage img = ImageIO.read(imageURL); File outputfile = new File("saved.png"); ImageIO.write(img, "png", outputfile); try {

问题 how can I make jar for my java files in linux? I have this situation: I have in directory src this stuff: Client.java //source code GUI.java // source code miglayout-lib.jar //external lib icons // folder in which are 20 jpeg pictures when I want to compile it I use javac -cp "miglayout-lib.jar:." *.java when I want to run it I use java -cp "miglayout.jar:." Klient //cause Klient is class with main. How can I make some build file or script (something like make) which will make me one jar file

问题 I would like to associate a specific file type with my application, so when I double-click one of the files of this specific type, my application opens. This works just fine, but the file I double-clicked does not get passed as an argument to my program. If I for instance associate my application with txt files and I double-click todo.txt , my application opens, but I have no idea which txt file I double-clicked. From what I can read, this is how it's supposed to work on OS X, and instead of

问题 When exporting a project as a Runnable JAR file using Eclipse, there are three choices: 1. Extract required libraries into generated JAR 2. Package required libraries into generated JAR 3. Copy required libraries into a sub-folder next to the generated JAR However, it seems that only one of the three choices could be chosen from the Runnable JAR File Export window. I wonder if there are some ways that could mix up these methods, e.g., extracting some of the files while packaging the rest?

问题 I have a java project and i need to create jar file from my project . any body can tell me what is the simplest way to make this? 回答1: From scratch.. with CMD The command line is what almost every other application will use to build your JAR file. They just wrap it up a little nicer for you. In truth, it's very simple to do yourself. Obviously Java have explained this way in detail so there is no sense in me repeating it. Note : You need to have your JDK/bin directoy appended onto your %PATH%

问题 Currently I have a deployed executable jar file that creates large (7+ Gb) minidump files when it crashes. I would like to have a text representation of what caused the crash, not a binary file of the JVM state. I've tried using the information found in this CodeRanch post and the documentation that I've found in the Java documentation doesn't seem to help. I also referenced this question but there's no definitive answer. Is there a typical way this is done that I'm not aware of? 回答1: I found

问题 When using Maven to build an executable JAR, how do I specify the JVM arguments that are used when the JAR is executed? I can specify the main class using <mainClass> . I suspect there's a similar attribute for JVM arguments. Specially I need to specify the maximum memory (example -Xmx500m). Here's my assembly plugin: <plugin> <artifactId>maven-assembly-plugin</artifactId> <configuration> <descriptorRefs> <descriptorRef>jar-with-dependencies</descriptorRef> </descriptorRefs> <archive>

问题 I work on Eclipse (Juno with JDK7), and the program runs (on Eclipse) fine. My problematic lines are: URL imageURL = new URL("http://www.idautomation.com/ocr-a-and-ocr-b-fonts/new_sizes_ocr.png"); RenderedImage img = ImageIO.read(imageURL); File outputfile = new File("saved.png"); ImageIO.write(img, "png", outputfile); But when i export the project to a jar file and try to run it via windows (7- 64 bit) command line, the following error appears: Exception in thread "main" java.lang.reflect
