Hello, I am not sure if this is a bug or something specific to our implementation, so wanted to share that with others. Please forgive my idiocy.
We took a verbose classloading on Windows and it loaded two classes from two different locations. 1) *SomeUtils*.class from *com.my.package.name <http://com.my.package.name>* - placed in WEB-INF/classes 2) *SomeOtherUtils*.class from *com.my.package.name <http://com.my.package.name>* - placed in myjar.jar in WEB-INF/lib In Windows, we can load the SomeUtils.class from the "classes" directory (correct) and SomeOtherUtils.class from jar (in lib directory, also correct). The class *SomeUtils *exist in *both **lib *and *classes*. but as per documentation, webapp loader will load things from classes dir first, and then lib. And it won't load the same class from *lib *if found in *classes *first. And it also honours the contract "Child loader must not load same class loaded by parent". So identical package name isn't a problem. When we deployed in Linux, it didn't quite happen. We saw that "lib" was always looked up first. We understand that SomeUtils.class duplicated in both lib and classes is not a "Good" practice. But what we don't understand is why webapp classloader isn't searching classes directory and finding it first? Is there something fundamentally different when it comes to Linux e.g. ordering/searching which is out of tomcat's control? We don't have the verbose log from Linux yet, but meanwhile any info is helpful. Thanks,
