问题 I need to get a resource image file in a java project. What I'm doing is: URL url = TestGameTable.class.getClass(). getClassLoader().getResource("unibo.lsb.res/dice.jpg"); The directory structure is the following: unibo/ lsb/ res/ dice.jpg test/ ..../ /* other packages */ The fact is that I always get as the file doesn't exist. I have tried many different paths, but I couldn't solve the issue. Any hint? 回答1: TestGameTable.class.getResource("/unibo/lsb/res/dice.jpg"); leading slash to denote

问题 I have been struggling with this issue all day and have had no success. I am basically trying to get an image resource from another apk. So if com.example.app has an image called image1.png in the res folder, i want com.example2.app to be able to gain access to that resource and place it in an imageview. I know you have to use PackageManager.getResourcesForApplication, but i have still been unsuccessful in getting the actual resource. Any help would be awesome! 回答1: Figured it out... final

问题 I have an exe packaged inside my jar file and I am trying to copy it to a temporary location so that i can run it using Desktop.browse() , to do this I set up a scanner with the input stream constructor using class.getResourceAsStream , and then with a printwriter wrote that all to a file. The problem that occurred says that the exe is invalid. I think this is due to some binary data being lost. If anyone can help please post a comment. Scanner sc = new Scanner(ClassBuilder.class

问题 I have a file watstheday.txt in my src/main/resources folder of my project as shown in the image file below. I read the file through a getResourceAsStream() method of the ClassLoader and perform further actions in my code which is working perfectly. However if I try to perform a check if the file exists through the below code it always returns false. try { ClassLoader classLoader = getClass().getClassLoader(); System.out.println("!@#!@# so difficult to be simple..."+classLoader.getResource(

问题 I'm trying to acces a File inside the .jar. In Netbeans, this: System.out.println(new File(this.getClass().getResource("Image.jpg").getFile()).exists()); Prints out: true After building however, it prints false. The file is definitely in the .jar, next to the .class file, and something like this: new Frame(){ @Override public void paint(Graphics g){ try{ g.drawImage(ImageIO.read(this.getClass().getResource("Image.jpg")), 0, 0, this); } catch(Exception e){e.printStackTrace();} } }.setVisible

问题 Not sure how this is possible. I re-read up on getResourceAsStream and it's always returning null. InputStream source = this.getClass().getResourceAsStream("test.xml"); Right next to test.java in the Finder (using OS X and Eclipse) is test.xml I can open it in TextWrangler and view it as existing with data inside.
