Java.lang.ClassNotFoundException: org.springframework.core.io.Resource

Question

I am using spring 4.0.5, Hibernate 4.3.5 and JSF for web development in eclipse and this is the contents of my lib folder:

When I run my project, I get this error:

 java.util.concurrent.ExecutionException: org.apache.catalina.LifecycleException: Failed to start component [StandardEngine[Catalina].StandardHost[localhost].StandardContext[/EMaEval]] at java.util.concurrent.FutureTask.report(Unknown Source) at java.util.concurrent.FutureTask.get(Unknown Source) at org.apache.catalina.core.ContainerBase.startInternal(ContainerBase.java:1123) at org.apache.catalina.core.StandardHost.startInternal(StandardHost.java:799) at org.apache.catalina.util.LifecycleBase.start(LifecycleBase.java:150) at org.apache.catalina.core.ContainerBase$StartChild.call(ContainerBase.java:1559) at org.apache.catalina.core.ContainerBase$StartChild.call(ContainerBase.java:1549) at java.util.concurrent.FutureTask.run(Unknown Source) at java.util.concurrent.ThreadPoolExecutor.runWorker(Unknown Source) at java.util.concurrent.ThreadPoolExecutor$Worker.run(Unknown Source) at java.lang.Thread.run(Unknown Source) Caused by: org.apache.catalina.LifecycleException: Failed to start component [StandardEngine[Catalina].StandardHost[localhost].StandardContext[/EMaEval]] at org.apache.catalina.util.LifecycleBase.start(LifecycleBase.java:154) ... 6 more Caused by: java.lang.NoClassDefFoundError: org/springframework/core/io/Resource at java.lang.Class.getDeclaredFields0(Native Method) at java.lang.Class.privateGetDeclaredFields(Unknown Source) at java.lang.Class.getDeclaredFields(Unknown Source) at org.apache.catalina.util.Introspection.getDeclaredFields(Introspection.java:106) at org.apache.catalina.startup.WebAnnotationSet.loadFieldsAnnotation(WebAnnotationSet.java:261) at org.apache.catalina.startup.WebAnnotationSet.loadApplicationListenerAnnotations(WebAnnotationSet.java:90) at org.apache.catalina.startup.WebAnnotationSet.loadApplicationAnnotations(WebAnnotationSet.java:63) at org.apache.catalina.startup.ContextConfig.applicationAnnotationsConfig(ContextConfig.java:403) at org.apache.catalina.startup.ContextConfig.configureStart(ContextConfig.java:879) at org.apache.catalina.startup.ContextConfig.lifecycleEvent(ContextConfig.java:374) at org.apache.catalina.util.LifecycleSupport.fireLifecycleEvent(LifecycleSupport.java:117) at org.apache.catalina.util.LifecycleBase.fireLifecycleEvent(LifecycleBase.java:90) at org.apache.catalina.core.StandardContext.startInternal(StandardContext.java:5355) at org.apache.catalina.util.LifecycleBase.start(LifecycleBase.java:150) ... 6 more Caused by: java.lang.ClassNotFoundException: org.springframework.core.io.Resource at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1720) at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1571) ... 20 more

How can I solve this problem?

Answer 1

Make sure the following jar file is included in your class path and lib folder.

spring -core-3.0.5.RELEASE.jar

if you use maven make sure you specify the dependency for spring -core-3xxxxx.jar

 <dependency> <groupId>org.springframework</groupId> <artifactId>spring-core</artifactId> <version>${org.springframework.version}</version> </dependency> 

Note. Replace $ {org.springframework.version} with the version number.

Answer 2

org.springframework.core.io.Resource is part of spring-core-<version>.jar

But this lib is already in your lib folder. Therefore, I assume this is just a deployment problem. - Try to clean your server and reinstall the application.

Answer 3

Right click on your project -> Properties -> Deploy Assembly.

In the left pane, click Add and add Project and External Dependencies .

' Project and External Dependencies ' will have all w760-related banks associated with your application

Answer 4

There is a version conflict between JAR / dependency, please check that all Spring versions are the same. if you use maven, uninstall the dependency version and use Spring.io dependency.it to handle the version conflict. Add this to your pom

  <dependency> <groupId>io.spring.platform</groupId> <artifactId>platform-bom</artifactId> <version>2.0.1.RELEASE</version> <type>pom</type> <scope>import</scope> </dependency> 

Answer 5

I got the same error even though the jar is in the lib directory and added to the deployment assembly in Eclipse.

So I doubted two things,

1. Some problems with the Weblogic cache - since this application was deployed before, and I tried to redeploy it after some changes

2. The file itself is damaged due to partial download, etc.

So I downloaded the flask and deleted everything in the directory - .. \ Oracle_Home \ user_projects \ domains \ base_domain \ lib and deployed again , and everything went well.
