I have a Jersey WebApp running on Tomcat and want to integrate the MarvinFramework for ImageProcessing. Basically I want to reduce noise, grayscale and scale an Image for further processing.

The Marvin Framework relies on custom Plugins for their specific prupose, and those Plugins I want to use. But since the Framwork has its own ClassLoader, that loads the plugins JAR dynamically at runtime from an absolute location inside the project, I am confused where to put the files or how to configure the WebApp, that the ClassLoader is able load the JARs. I recreated the directory-structure for standalone Apps inside my WEB-INF/lib-dir with the Deployment Assembly but I had no success.

I am getting a:

java.io.FileNotFoundException: .\marvin\plugins\image\org.marvinproject.image.color.grayScale.jar

when I try: 

marvinImagePlugin = MarvinPluginLoader.loadImagePlugin("org.marvinproject.image.color.grayScale.jar");

the jar-file should be located by the deploment assebmly in:

WEB-INF/lib/marvin/plugins/image

You can set the library path with MarvinDefinitions.setImagePluginPath(path); to a path of your choice. In this case you have to manually put the files to the JVM and they are not deployed automatically.

    better than putting them in the JVM which can change its better to put it in a newtral path like /var/YourProjectname/v1/lib and point to that in sh or .bat file as a environment or system variable – tgkprog May 29 '14 at 19:03
