问题
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.
