Try doing a complete clean of the target deployment directory for the app to get rid of any stale library jars  Make a fresh build and check that commons-logging jar is actually being placed in the correct lib folder  It might not be included when you are building the library for the application

Two options  at least     Add the commons-logging jar to your file by copying it into a local folder    Note  linking the jar can lead to problems with the server and maybe the reason why it s added to the build path but not solving the server startup problem   So don t point the jar to an external folder   OR      If you really don t want to add it locally because you re sharing the jar between projects  then      If you re using a tc server instance  then you need to add the jar as an external jar to the server instance run configurations   go to run as  run configurations      your tc server instance   and then the Class Path tab   Then add the commons-logging jar

If you re using maven for managing dependencies  add the following line in your pom xml    lt dependency gt           lt groupId gt commons-logging lt  groupId gt           lt artifactId gt commons-logging lt  artifactId gt           lt version gt 1 1 1 lt  version gt   lt  dependency gt

If you re running this on Android then note that apparently java beans package is not complete on Android  To attempt to fix it on Android try the following    Download android-java-air-bridge jar  currently the download button is on the bottom of the page or direct link here  Copy the downloaded jar to your  APPROOT  app libs directory  or link the jar in any other way  Change the import      statements to that of air-bridge  Eg import javadz beanutils BeanUtils instead of import org apache commons beanutils BeanUtils  Clean and rebuild the project   source 1  source 2  I apologise as I realise this is not exactly answering the question  though this SO page comes up a lot when searching for android-generated NoClassDefFoundError  Failed resolution of  beanUtils errors

I have already included common-logging1 1 1 jar and       Are you sure you spelled the name of the JAR file exactly right  I think it should probably be commons-logging-1 1 1 jar  note the extra - in the name   Also check if the directory name is correct   NoClassDefFoundError always means that a class cannot be found  so most likely your class path is not correct

commons-logging-1 1 1 jar or jcl-over-slf4j-1 7 6 jar al  If you are using maven  use the below code    lt dependency gt       lt groupId gt org slf4j lt  groupId gt       lt artifactId gt jcl-over-slf4j lt  artifactId gt       lt version gt   slf4j version  lt  version gt   lt  dependency gt

I generally assign the classpath to a variable and then verify it   I ve written a small ruby script which I include in a my startup scripts which validates the classpath before launching java   Validating the classpath before the JVM starts has saved me lots of time troubleshooting these types of problems
