classpath

It is said that java 9 modules will solve classpath hell. However, I am thinking about the following situation: Module A uses modules B and C. Both modules will export a class with same name and package. How will the classloading issue be solved here? This situation is forbidden in the Java 9 module system. If two modules in the same layer have the same package, Java 9 will fail at startup with an error: java.lang.LayerInstantiationException: Package <package_name> in both module <moduleB_name> and module <moduleC_name> 来源： https://stackoverflow.com/questions/44086361/java-9-modules-and

Anyone who uses Java regularly knows the amount of trouble multiple jars in classpath can give us. I am looking for a tool which will help me - Search for class files inside jars in Classpath Search for class files inside jars in a specific location Maybe too much to ask for but show me if the same class is present in multiple jars. Also needless to say it should be fast. Most of the tools i have evaluated are very slow and not upto the mark. Any tools for the above purpose greatly appreciated. Currently i use WinRar achieve search(which BTW is really fast) to search for class files inside

Is there a way for Eclipse to output all the Jars I would like to define on my ClassPath variable in the Manifest when exporting a project as a jar? I would like to be able to just click on all the jars I need my project to depend on, and then have Eclipse output it all like: ClassPath: . /lib/somejar.jar /lib/otherjar.jar Thanks Yes, there is: Eclipse > File > Export > Java > Runnable JAR File > "Copy required libraries into a sub-folder next to the generated JAR" . It will create a MANIFEST.MF with all the classpath entries of your Java project. You need to have a working launch

I expose my context : I have two Java programs that run on a unique Weblogic Server : program A and program B. These ones are launched by two ksh : programA.ksh and programB.ksh Both need C.jar but in different versions (but with exactly the same package and classes) : program A need C-1.0.jar program B need C-2.0.jar I precise that both programs share the same weblogic classpath. So, my classpath contains in that order : ..... C-1.0.jar C-2.0.jar ..... How can I do so that each program finds its good library ? For instance, with my actual configuration, program B will always use C-1.0.jar

I've read so many Q&A here about tools available to find out unused JARs, such as: loosejar Classpath Helper My question here is, are there any impacts (such as loading of classes into memory, performance, etc.) of having unused JARs in the classpath either at compile time or run time? Question applies to both running as a Standalone program and Web Server (Apache Tomcat), though I initially thought about only Standalone programs. NOTE: I'm running JDK 6u32 (64-bit). Are there any impacts (such as loading of classes into memory, performance, etc.) of having unused JARs in the classpath either

I have the below build file for Ant and trying to use the target 'run' for executing the program. <property name="springjar" location="E:/Tools/spring-30/dist/" /> <property name="logjar" location="E:/Tools/commons-logging-1.1.1/" /> <patternset id="jar.files"><include name="**/*.jar"/></patternset> <path id="springlearn.classpath"> <fileset dir="${springjar}"><patternset refid="jar.files"/></fileset> <fileset dir="${logjar}"><patternset refid="jar.files"/></fileset> </path> <target name="run" depends="dist" description="Execute the Java Program"> <java dir ="." fork="true" jar="dist\app.jar"

I am trying to use ClassLoader getResourceAsStream() My Direcory structure is like below: Project1 -src -main -java -webapp -WEB-INF -MYLOC -someprops.properties For classloader.getResourceAsStream("MYLOC/someprops.properties") works fine. But now I have to move the properties file outside of the .war, like in C:\someprops.properties But, classloader.getResourceAsStream("C:\someprops.properties") does not work. Can it not use an absolute path? If you have a native file path then you don't need to use getResourceAsStream , just create a FileInputStream in the normal way. Properties props = new

I would like to use an Eclipse classpath variable to resolve the attached source JAR file for a library in my classpath. This is the contents of my current ".classpath" file in Elcipse (Indigo): <?xml version="1.0" encoding="UTF-8"?> <classpath> <classpathentry kind="src" path="src"/> <classpathentry exported="true" kind="con" path="org.eclipse.jdt.launching.JRE_CONTAINER"/> <classpathentry exported="true" kind="lib" path="lib/ApacheCommons/commons-logging.jar"/> <classpathentry exported="true" kind="lib" path="lib/Spring-WS/spring-ws-1.5.8-all.jar"/> <!-- [other entries] --> <classpathentry
