classpath

I'm trying to run the sample "Hello World" from the LWJGL website From this link: LWJGL "Getting Started" I'm trying to do this via the command line, just so I understand the "behind the scenes" a bit better. I've managed to compile without any errors, but when I try to run the program I'm getting this error: C:\JavaProjects\LearningLWJGL>java -classpath .;./lib/*.jar -Djava.library.path=C:\Windows\System32 HelloWorld Error: A JNI error has occurred, please check your installation and try again Exception in thread "main" java.lang.NoClassDefFoundError: org/lwjgl/glfw/GLFWKeyCallback at java

I have an executable jar that has one class file with a wrong value. I requested that file from the author and corrected the value. Now I want to compile it and add the compiled class file into the jar and run it. Not surprisingly I get multiple "cannot find symbol" errors for references of custom object that were in the jar file. I tried to compile the file by referencing the jar file in the classpath like so C:/> javac file.java -classpath C:/folder/where/jar/is but this doesnt seem to work... I get the same errors as if just doing C:/> javac file.java Is there a way to compile this

This is only for testing. object Scala extends Controller { def session = WebSocket.using[String] { request => val interpreter = new IMain() val (out,channel) = Concurrent.broadcast[String] val in = Iteratee.foreach[String]{ code => interpreter

I have an Eclipse project with the following directory structure: MyProj/ src/main/java/ com.me.myproject.widgets Widget.java src/main/config widget-config.xml src/test/java com.me.myproject.widgets WidgetTest.java src/test/config widget-test-config.xml The Widget class reads its config (XML) file in from anywhere on the classpath and uses it to configure its properties. I am trying to just get WidgetTest 's test cases (all written with JUnit) to run inside Eclipse when I right-click the file and go to Run As >> JUnit Test . I assume I'll have to actually run it as a customized Run

I am working on a Windows PC and have cygwin on it! I have organized all my jars under a directory within a few directories! I am writing a bash script to set the CLASSPATH by iterating through the directory that is passed as a parameter as follows: for JAR_FILE in `ls *.jar` do CLASSPATH="$DIRECTORY_TO_LOOK_FOR_JARS"/$JAR_FILE:$CLASSPATH done Whenever there are spaces in the directory that is passed like /cygdrive/c/Documents and Settings/user/My Jars and I run java -cp $CLASSPATH somepackage.someclass , it throws an error stating that the class and is not found, because the CLASSPATH

I have a project located at /home/myself/workspace/Project1, for which I created an SDK from a Python 2.7.3 Virtualenv I have setup. This project uses some external code that I have in an accessible directory, e.g. /home/myself/LIBRARY; this directory contains several directories with code, docs etc.... For example, there is a module "important_util" located at /home/myself/LIBRARY/mymodule/important_util.py. Now, I added the whole dir /home/myself/LIBRARY in the SDK Classpath, and in the Editor window it appears just fine. The imports and calls are recognized and I can also navigate through
