Classes working even after removing jar

[Gurumurthy Ramamurthy]

Guys,

I have a typical scenario.
I am using a web application. Some class files are getting accessed from a .jar file. Now, I expect the system to give me errors/exceptions when I remove the .jar file.

So, I have removed the .jar file.

Instead of getting errors, the application is running smoothly even after removing the .jar file. I guess a copy of that .jar file would have been stuck somewhere.

Is there anyway to find out where that .jar file is sticking in the system or any other way to find out? Like any JRE caching JAR file or any JAR caching concepts...i don't know...just throwing ideas.

This is on windows only.

Thanks,
Guru

Do check the <jre_root>/lib folder if your jar files are there. This is the default place.

Just to be clear, have you restarted the application after removing the jar files? If you remove them during the runtime of an application they may have been read and cached by the JVM already.
