Java error: java.lang.ClassNotFoundException:

Question

Let me preface this by saying I'm not a Java developer, but rather a Python developer who needs to leverage a small portion of Java code for a project. :-)

That being said, I'm receiving the following error:

Caused by: java.lang.ClassNotFoundException: CustomSecurePropertyPlaceholderModule

using the following code:

I've ensured src/main/java is on the build path within the run config (the file CustomSecurePropertyPlaceholderModule resides there). I also see that shared_resources/target/classes is set as the output folder in the run config as well. Any ideas why I'm still receiving this error?

In Java, classes are usually in packages.

Like, com.yourself.CustomSecurePropertyPlaceholderModule

Try putting your class (I hope you have it) into src/main/java/com/yourself, prepend with package com.yourself; and use

<spring:bean id="secure-property-placeholder" class="com.yourself.CustomSecurePropertyPlaceholderModule">
