classpath

问题 I am trying to implement a method that when called, get a string from a particular resource in the jar that the class is loaded from. For example: import mypath.myclass; //from a jar String result = gitid.getGitId(myclass.class); On the backed I am currently using: InputStream is = null; BufferedReader br = null; String line; is = c.getResourceAsStream("/com/file.text"); The problem is I keep getting the same resource for no matter what class I give it. I have also tried: is = c

问题 I added a classpath variable (via eclipse's build path) that points to a cache of jars. While this folder is represented in eclipse's folder view, the contained jars are not recognized for some reason. For example, when I import a class that is present in a jar in the cache (and thus the added classpath variable), eclipse indicates that the class can not be resolved. Any ideas what is wrong and how to resolve it? 回答1: You have to make sure that the jar(s) that you want are actually included

问题 I'm trying to write an SVN Post-Commit hook to generate javadoc on a webpage whenever someone submits any changes to relevant files. I was new to the hook concept, but I didn't expect to run in any strange errors when generating the javadoc. java.lang.ClassCastException: com.sun.tools.javadoc.ClassDocImpl cannot be cast to com.sun.javadoc.AnnotationTypeDoc at com.sun.tools.javadoc.AnnotationDescImpl.annotationType(AnnotationDescImpl.java:46) at com.sun.tools.doclets.internal.toolkit.util.Util

问题 I can run my Java Swing application from Eclipse without problems. But when I run it from a .jar-file, the images fails to load. I load my images with: setIconImage(Toolkit.getDefaultToolkit(). getImage(getClass().getResource("../images/logo.png"))); How can I load the images so they work even when I'm running from a .jar-file? The images is in the same Jar-file, in the packet com.example.images and the class where they are used is in com.example.gui.dialogs 回答1: Use the absolut path inside

问题 Summary Java environment variables correctly set, as seen from echo-ing them. However, jars are only seen when explicitly included with javac command. Details This is not specifically related to graphics and OpenGl, certain the problem is related to classpaths, ie the importing of third-party jar files. Using Windows XP SP3, JDK 1.7.0_13 On Windows xp, the system environment variables PATH/JAVA_HOME/CLASSPATH have been set/added-to to include these directories: C:\Documents and Settings

问题 We have small problem in adding the external directory (having config.properties) to the classpath. If we add this to the classpath, we should be able to read it in the web application. There are some spring applications in web application which will read the external properties file. I don't find the correct solution any where ? Could you please point me the right direction ? Thanks, Rama Krishna 回答1: I had the similar requirement and I did the followings: 1) Added the properties folder path

问题 Structure of files in my jar is: com/my/Main.class META-INF/MANIFEST.MF RXTXcomm.jar Manifest.mf consist: Manifest-Version: 1.0 Main-Class: com.my.Main Class-Path: RXTXcomm.jar (empty line present) When I run my jar as: java -jar my.jar I get: Exception in thread "main" java.lang.NoClassDefFoundError: gnu/io/SerialPortEventListener What is wrong? 回答1: What is wrong? You have packaged the jar dependency inside your main jar. The intention of Class-Path is to add an external jar to the

问题 Does the GWT compiler have a notion of its own "classpath" that is separate from the normal compile-time classpath? Does a GWT app (and its internal workings) have the notion of its own classpath that is separate from the normal JRE runtime classpath? 回答1: GWT has the notion of modules. Each module does declare what packages are in its source path. Modules can extend other modules. Every Class the GWT compiles has to be in the source path of one module your main module extends from. The

问题 I have a web application that uses JAXB 2. When deployed on an Oracle 10g Application Server, I get errors as soon as I try to marshal an XML file. It turns out that Oracle includes JAXB 1 in a jar sneakily renamed "xml.jar". How I can force my webapp to use the version of the jaxb jars that I deployed in WEB-INF/lib over that which Oracle has forced into the classpath, ideally through configuration rather than having to mess about with classloaders in my code? 回答1: I assume you use the

问题 We have an installation of Weblogic 10.3.6. An application running on it needs the following jar com.oracle.ws.http_client_1.3.0.0.jar The above jar is located in the server bundle Oracle\Middleware\modules\com.oracle.ws.http_client_1.3.0.0.jar What's the right approach? Should this jar (appears to be a system library written by Oracle, not found on mvnrepository site) be added to the server classpath or should I add it to the application archive (war)?? Thanks. Update: Also the above jar
