Add the jar files on class path NOT modulepath  Eclipse Image

org springframework core io Resource is part of spring-core- lt version gt  jar  But this lib is already in your lib folder  So I guess it is just a Deployment Problem  -- Try to clean your server and redeploy your application

User · Answer

Make sure  following jar file included in your class path and lib folder   spring-core-3 0 5 RELEASE jar    if you are using maven  make sure you have included dependency for spring-core-3xxxxx jar file   lt dependency gt    lt groupId gt org springframework lt  groupId gt    lt artifactId gt spring-core lt  artifactId gt    lt version gt   org springframework version  lt  version gt   lt  dependency gt    Note   Replace   org springframework version  with version number

I received same error despite jar being in lib directory  amp  added to deployment assembly in Eclipse    So I doubted two things     1 Some Weblogic cache issue - as this app was deployed before  amp  I was trying to redeploy after some changes  2 Jar itself is corrupt due to partial download etc   So I re downloaded the jar  amp  deleted everything in directory -    Oracle Home user projects domains base domain lib  and redeployed again  amp  all went well

There is a version conflict between jar dependency please check all version of spring is same  if you use maven remove version of dependency and use Spring io dependency it handle version conflict  Add this in your pom    lt dependency gt               lt groupId gt io spring platform lt  groupId gt               lt artifactId gt platform-bom lt  artifactId gt               lt version gt 2 0 1 RELEASE lt  version gt               lt type gt pom lt  type gt               lt scope gt import lt  scope gt     lt  dependency gt

Right-Click on your project -  Properties -  Deployment Assembly   On the Left-hand panel Click  Add  and add the  Project and External Dependencies      Project and External Dependencies  will have all the spring related jars deployed along with your application
