classpath

If there are two JAR files in the classpath, both containing a resource named "config.properties" in its root. Is there a way to retrieve both files similar to getClass().getResourceAsStream() ? The order is not relevant. An alternative would be to load every property file in the class path that match certain criterias, if this is possible at all. You need ClassLoader.getResources(name) (or the static version ClassLoader.getSystemResources(name) ). But unfortunately there's a known issue with resources that are not inside a "directory". E.g. foo/bar.txt is fine, but bar.txt can be a problem.

I have written a Java code which imports an external jar file. How can I compile and run it on the command-line? Thanks in advance! Compiling from the command-line: javac -cp path_to_jar1.jar:path_to_jar2.jar Example.java Running: java -cp .:path_to_jar1.jar:path_to_jar2.jar Example For Windows, use ; as a path-separator (instead of : ). 来源： https://stackoverflow.com/questions/4421730/importing-external-jar-files

I know we can do something like this: Class.class.getResourceAsStream("/com/youcompany/yourapp/module/someresource.conf") to read the files that are packaged within our jar file. I have googled it a lot and I am surely not using the proper terms; what I want to do is to list the available resources, something like this: Class.class.listResources("/com/yourcompany/yourapp") That should return a list of resources that are inside the package com.yourcompany.yourapp.* Is that possible? Any ideas on how to do it in case it can't be done as easily as I showed? Note: I know it is possible to know

For my current purposes I have a Maven project which creates a war file, and I want to see what actual classpath it is using when creating the war . Is there a way to do that in a single command -- without having to compile the entire project? One idea is to have Maven generate the target/classpath.properties file and then stop at that point. To get the classpath all by itself in a file, you can: mvn dependency:build-classpath -Dmdep.outputFile=cp.txt Or add this to the POM.XML: <project> [...] <build> <plugins> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-dependency
