classnotfoundexception

I'm trying to run my junit test (to verify that a properties file loads correctly) but I get ClassNotFoundException although the class is there and all required libraries are there too. Here it is the error I get : Class not found ConfigurationManagerTest java.lang.ClassNotFoundException: ConfigurationManagerTest at java.net.URLClassLoader$1.run(URLClassLoader.java:200) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:188) at java.lang.ClassLoader.loadClass(ClassLoader.java:306) at sun.misc.Launcher$AppClassLoader.loadClass

How can I resolve my class from a different jar with same structure like another Note : Though the jars in question contains the word selenium but the question here have no direct relation with selenium Till a few days back PhantomJSDriver was released bundled along with selenium-server-standalone-v.v.v.jar . So my Class was working fine as: import java.io.File; import org.openqa.selenium.WebDriver; import org.openqa.selenium.phantomjs.PhantomJSDriver; public class A_PhantomJS { public static void main(String[] args) { File path=new File("C:\\Utility\\phantomjs-2.1.1-windows\\bin\\phantomjs

When I run the following snippet to connect to datasource to get the data out through queries : try { String driver = "com.microsoft.jdbc.sqlserver.SQLServerDriver"; Class.forName(driver); String Url = "jdbc:sqlserver://localhost:1433;databaseName=movies"; Connection connection = DriverManager.getConnection(Url,"sa", "xxxxxxx); // Context initContext = new InitialContext(); // Context envContext = (Context)initContext.lookup("java:comp/env"); // DataSource ds = (DataSource)envContext.lookup(""); // Connection connection = ds.getConnection(); String query_name = "select name from list where

I have a strange issue. I have an app which I deployed on an Android 4.4 device and use Otto library. I deployed the app on an Android 5.0 device. It still works. I retried on the 4.4 and the app won't launched. Apparently, it tries to use PersistableBundle.class which a API 21 class. Here my log : Caused by: java.lang.ClassNotFoundException: Didn't find class "android.os.PersistableBundle" on path: DexPathList[[zip file "/data/app/fr.myapp.apk"],nativeLibraryDirectories=[/data/app-lib/fr.myapp, /vendor/lib, /system/lib]] at dalvik.system.BaseDexClassLoader.findClass(BaseDexClassLoader.java:56

Most of the devices can run my app but I got this error report : java.lang.RuntimeException: Unable to instantiate activity ComponentInfo{com.company.app/com.company.app.MainActivity}: java.lang.ClassNotFoundException: com.company.app.MainActivity in loader dalvik.system.PathClassLoader[/mnt/asec/com.company.app-1/pkg.apk] at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2755) at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:2854) at android.app.ActivityThread.access$2300(ActivityThread.java:136) at android.app.ActivityThread$H.handleMessage

上一篇博文中提到通过替换weblogic自带的commons-fileupload.jar来解决FileUpload类的NoSuchMethodError问题。在完成替换后，该问题得到顺利解决，但是也会引发其他的一些问题，下面提到的这个问题就跟 commons-fileupload.jar的替换有关系。 现象 weblogic替换了 commons-fileupload.jar后，系统中原先的导入功能运行报错： java.lang.ClassNotFoundException:org.apache.commons.io.output.DeferredFileOutPutStream 分析 由于是类找不到的异常，所以检查有没有类似weblogic自带的commoms-io包版本过低的问题，经过一番检查后，发现weblogic都没提供该jar。应用程序包提供的commons-io包又不存在版本问题。一个头疼的问题。纠其原因还是对weblogic的类加载机制不太清楚。 最后网上提到一个说法，weblogic在加载 commons-fileupload.jar前需要先加载 commons-io.jar 解决办法 由于我的weblogic环境实在启动文件中通过CLASSPATH来指定 commons-fileupload.jar的加载 ，所以在CLASSPATH中指定 commons-io

I have gone through this thread What causes and what are the differences between NoClassDefFoundError and ClassNotFoundException? This is what one of the ans,which has max ups, in thread is : NoClassDefFoundError :"So, it appears that the NoClassDefFoundError occurs when the source was successfully compiled, but at runtime, the required class files were not found . This may be something that can happen in the distribution or production of JAR files, where not all the required class files were included." ClassNotFoundException : As for ClassNotFoundException, it appears that it may stem from

I tried to create/run a basic JSP and ran into the following error. I saw that other people have had similar problems, however, I haven't been able to find (or properly implement) a solution to the problem at hand yet. Any help would be appreciated!
