classpath

问题 How do you add a folder (e.g. a resource folder containing arts) to the classpath of a netbeans project? I managed to do that manually via editing the NB generated jar file of the project (that is its MANIFEST.MF file + copying the resources manually), but there should be a way to tell netbeans as well to mind the resources, no? The folder structure looks like this: /project/art/ /project/dist/lib/ /project/dist/art/ /project/dist/project.jar /project/lib/ /project/src/ I don't want to

问题 I am not clear about this. When I run a java App or run an Applet in applet viewer, (in the IDE environment), System.getProperty("java.class.path") gives me the same as System.getenv("CLASSPATH") which is the CLASSPATH defined in my env variable. But when I deploy my applet to webserver and access it from the same computer as a client, I get different results for the two. ( System.getProperty("java.class.path") only points to JRE home and System.getenv("CLASSPATH") returns null). And here is

问题 Command: javah -jni JavaHowTo Result: error: cannot access JavaHowTo class file for JavaHowTo not found javadoc: error - Class JavaHowTo not found. Error: No classes were specified on the command line. Try -help. I have set the class path correctly, but still i am getting this javah error. Any solution for this will be much helpful. 回答1: Try javah -jni com.example.JavaHowTo where com.example is your package. You also need to run javah from the directory containing com/example/JavaHowTo.class

问题 This question already has answers here : Including all the jars in a directory within the Java classpath (25 answers) Closed 4 years ago . From the command line, how do I set the Java CLASSPATH option to point to one or more directories containing multiple jar file? Are there wildcards for recursive directory and sub-directory support? (My JAR files are sorted in several sub-directories.) 回答1: If you are using Java 6 or higher you can use wildcards of this form: java -classpath ".;c:\mylibs\*

问题 So, I can do this very well: java mypackage.MyClass if ./mypackage/MyClass.class exists. I can also happily do this: java -cp myjar.jar mypackage.MyClass if the class file exists in the appropriate part of the jar. Easy stuff. But I can't for the life of me manage to do something like this: java -cp utilities.jar mypackage.MyClass where ./mypackage/MyClass.class exists, and where ./utilities.jar exists (not containing MyClass, of course). Am I about to feel stupid? 回答1: Possibly :) # On Unix

问题 From my readings, when you execute a command as follows: java -jar foo.jar Then the main classpath is ignored, and the classpath is taken from the manifest file. Further, the classpath declared on the command line is also ignored. So in: java -classpath /usr/local/jar/foobar.jar -jar foo.jar /usr/local/jar/foobar.jar is ignored. Lastly, I have read that the manifest file can only contain relative paths, within the jar file. So, how do you include absolute paths to external jars, that are

问题 Does anyone know of a way to set a specific classpath order in Maven2, rather than the random ordering I appear to experience at the moment? There are a number of legitimate reasons for wanting to do this: A vendor has supplied a patch jar, which contains overriding classes for a previously released jar and therefore the patch jar must appear first in the classpath ordering. Two jar's found on the classpath discovered by traversing pom dependencies contain the same class in the same package

问题 I'm using MATLAB R2007b, Java 1.6 SE, Eclipse Helios, and MySql 5 on Windows XP Pro SP3. I'm trying to create a class library that uses JPA annotations to access a MySql 5 database. The idea is that the MATLAB script instantiates these Java objects, which provide an API for accessing the DB. I can create my annotated classes, which work within Eclipse (i.e. JUnit test). I can export the code to a jar, which I can run from a command prompt. I update the MATLAB Java classpath using javaaddpath(

问题 I have read the previously posted questions. Some are vague and none solved my problem so I am forced to ask again. I have two simple classes, package One; import One.Inner.MyFrame; public class test { public static void main(String args[]) { MyFrame f= new MyFrame(); } } And the other class is, package One.Inner; import java.awt.*; import javax.swing.*; public class MyFrame extends JFrame { public MyFrame() { setPreferredSize(new Dimension(400,560)); setVisible(true); } } I am at base folder
