classpath

I developed an eclipse plugin and I'm trying to install it on another instance of eclipse. When I run/debug my plugin as an eclipse application everything works correctly. The problem occurs only after I install the plugin through the update site I created. I created a very simple update site which includes a single feature with my plugin packaged in it. After installing using the update site I can see my plugin in the plugin directory under the eclipse install dir and it correctly contains all the data that should be in there (I think). However, when I instantiate the plugin (by hitting the

I am trying to run a class from a JAR. This class is NOT the only main class in this jar. Also, it requires number of other jar files, which I have kept in the same directory as this Jar. The commands I have tried are as follows: (mydir is the directory in which all of my jars are located, using Windows platform) mysql-connector-java-5.1.13-bin.jar is needed for myProjImport.jar to run and com.mycomp.myProj.importer.csv.TestImporter is the class i am trying to run. "C:\Documents and Settings\user\workspace\myProjImport\src\conf\datasource.properties" and "C:\temp\apollo_claims_test.txt" are

I wrote a console application helloworld.java and ran javac helloworld.java ,and then java helloworld . This worked fine. I then created a package com.abc.project and moved helloworld.java into it(the package import statement is correctly generated which is package com.abc.project; ). And then i ran javac helloworld.java this worked also fine and generated the class properly. However, when I ran java com.abc.project.helloworld from the console, it threw an "class not found" error. Please can anyone advise what is the problem? Try running java -cp ABSOLUTE_PATH com.abc.project.helloworld Where

I'm using JDK 1.6 to run a small application. However I set a very massive classpath which includes a lot of classes. When I run the application will all classes in the classloader been loaded even if they're not actually used in my application? If not, how to force the classloader do so, and if yes, how to avoid it? Thanks! E.g.,I'm using ant 1.7 to run my application. Best Regards, Robert Ji No, The ClassLoader loads the class when the class is needed in memory. It doesn't load all classes at once as it can run out of memory. They are loaded when needed. But what "when needed" means, might

I'm trying to make a "clean maven" setup on some legacy project that uses ant scripts. I don't know much about ant, so my question might seem naive. I'm almost done, but the delivery ant script is failing, due to a redundancy in the classpath. If I understand the build, those lines should add to the classpath every lib in the "provided" scope : <artifact:dependencies pathid="dependency.classpath" scopes="provided"> <pom file="./pom.xml"/> </artifact:dependencies> And then this one : <path id="completecp"> <fileset dir="${ant.home}/lib"> <include name="*.jar" /> </fileset> <path refid=

I want to execute a Java class from a bat file and it include usage of opencsv.jar . Below is the code: @echo off set path=%PATH%;C:\Program Files (x86)\Java\jdk1.6.0\bin javac -cp opencsv.jar ArbitrageUsingThread.java java ArbitrageUsingThread I am getting the following error when running it. I think there is some problem with including opencsv.jar Can anyone help me with this? Error Exception in thread "main" java.lang.NoClassDefFoundError: au/com/bytecode/openc sv/CSVWriter at ArbitrageUsingThread.main(ArbitrageUsingThread.java:67) Caused by: java.lang.ClassNotFoundException: au.com
