Question

During start up of a simple Spring application deployed in STS, I get:

java.lang.ClassNotFoundException: org.springframework.instrument.classloading.tomcat.TomcatInstrumentableClassLoader

In my context.xml, I have:

<Loader
loaderClass="org.springframework.instrument.classloading.tomcat.TomcatInstrumentableClassLoader"
useSystemClassLoaderAsParent="false" />

Do I need to put the following jar in a particular location?
I tried to copy it in various lib dirs in my STS install dir

spring-instrument-3.1.0.RELEASE.jar

Answer 1

The jar needs to be on your classpath. Adding it to your project’s build path should be all you need to get it working.
