Question

Is it possible to use spring inside war bundle on felix? I use spring 3.0.5 with felix on glassfish 3.1

I tried to enter component-scan tag inside OSGI war bundle in felix, and I’m getting the below exception.

I saw that a similar bug was solved for Equinox, and what about felix? Is there a workaround or solution to this problem?

P.S: the same exception is thrown if I define path with * in web.xml contextConfigLocation, for example:

<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath*:META-INF/spring/*.xml</param-value>
</context-param>

Exception:

thank you for any tip

Answer 1

There are 2 workarounds I found to solve it. Still I’ll be glad to hear a real solution for felix.

The workarounds are:

1. Use equinox instead of felix 🙂
2. (an ugly one) Create a temporary folder and extract all the classes into it. Create a class org.eclipse.core.runtime.FileLocator with a function

public static URL resolve(URL url) throws IOException

and return the url of content from this folder, for example:

    String path = url.getPath(); 
    String str;
    if(path.contains("com")){
        str = path.substring(path.indexOf("com"));
    }
    return new URL("file:\\c:\\temp_classes\\"+str);
