问题 What is the difference between the maven scope compile and provided when artifact is built as a JAR? If it was WAR, I'd understand - the artifact would be included or not in WEB-INF/lib. But in case of a JAR it doesn't matter - dependencies aren't included. They have to be on classpath when their scope is compile or provided . I know that provided dependencies aren't transitive - but is it only one difference? 回答1: From the Maven Doc: compile This is the default scope, used if none is

问题 I've written a code that is supposed to be exporting a set of windows registry keys. I've successfully written the code and was able to also send the results of executing the code as a jar file to my email. However, while testing the jar file ( I've included the piece of code in the build.xml from the java website that will allow me to run the jar file out of the dist folder) I was able to get the desired results on my machine because I wrote the code on a windows 8.1 machine. While testing

问题 I deploy a WAR file in Tomcat. In addition I have a JAR file. Is it possible to make the classes in the JAR file available to services in the WAR file without changing the WAR file, or does it have be added to the WAR's WEB-INF/lib? I've tried adding the JAR to lib/ , but it doesn't work. Spring fails with org.springframework.beans.factory.BeanCreationException » java.lang.NoClassDefFoundError upon startup. EDIT I realized that I might have made myself an unsolvable and architectually ugly

问题 I'm developing an app that takes a XML file, sends it to a server, and receives some data in response. I need to package it into an .exe(legacy reasons), and for that I need a jar. I intend to use assembly plugin to package the app into a jar with all the dependencies. The app works fine when run from the IDE with mvn clean package exec:java -Dexec.mainClass="cz.tomasdvorak.eetdemo.Main" -Dexec.args="C:\\eetTesting\\testtrzba.xml" but as soon as I build the standalone .jar with mvn clean

问题 I am having problems having my Java programs see classes that are packaged in an external jar. I am running under Windows 7. I have the classes embedded in a jar called ParserUtilities.jar. I established the path with a CLASSPATH variable using the System utility and the Environment tab. I confirmed that the CLASSPATH is set correctly. When I type echo %CLASSPATH%, I see C:\Program Files\Java\externaljars\ParserUtilities.jar which is correct. But when I type java -jar Parse.jar (my executable

问题 I have done a custom JSF component (it looks like a combobox (icefaces selectonemenu)) but it uses a couple of images (png) and a bit of javascript. I jar everything, so then the developers use it as a jar copied in the web-inf/lib folder.

I jar everything and it works almost great, just the image and the JS, I do not get them to work. I do not know how
