Spring can't load xml configuration file

Question

This error blows my brain. All the junit tests is fine but when my application loads as plugin for another application I have an errors. The beans.xml is 100% at root of jar file but for some reason the main application, that loads my plugin can't find the file. Why?

In my application's boot method I call new ClassPathXmlApplicationContext("beans.xml"); throws

org.springframework.beans.factory.BeanDefinitionStoreException: IOException parsing XML document from class path resource [beans.xml]; nested exception is java.io.FileNotFoundException: class path resource [beans.xml] cannot be opened because it does not exist

or

new FileSystemXmlApplicationContext(getClass().getClassLoader().getResource("beans.xml").getPath()); throws

org.springframework.beans.factory.BeanDefinitionStoreException: IOException parsing XML document from URL [file:/C:/path/to/my.jar!/beans.xml]; nested exception is java.io.FileNotFoundException: C:\\path\\to\\my.jar!\\beans.xml (The system cannot find the path specified)

---

UPD: The problem was the application uses custom classloader that does not load resource files in root, META-INF and etc. but only classes

Answer 1

The FileNotFoundException that you get really points out that the beans.xml file is not in your jar at the place where you think it is. I would have a look inside that jar. You can for example open the jar with the 7-zip tool . I find that this provides useful insight when you get errors like the one you report.

Answer 2

If you're getting the FileNotFoundException it is because the file is not located where you're looking for it. The beans.xml file must be located in src/main/resources
