OSGi and Spring component-scan
Hello,
I'm a new guy to osgi and web app. I'm using Websphere application server
v8.5 Liberty Profile developing a web osgi bundle. So, arise blueprint is
being used by default. In that bundle, I used Spring
(context:component-scan) and got exceptions says
"java.io.FileNotFoundException: URL
[bundleresource://873.fwk-1377360156/com/xxx/xx/] cannot be resolved to
absolute file path because it does not reside in the file system".
I googled and it seems a common problem. But all solution I found is using
Eclipse Gemini blueprint. I'm wondering if there is another solution for
this?
Attached some of my code and config files as below:
Web.xml
<servlet>
<display-name>spring</display-name>
<servlet-name>spring</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>spring</servlet-name>
<url-pattern>/*</url-pattern>
</servlet-mapping>
spring-servlet.xml
<!-- Scans the classpath of this application for @Components to deploy as
beans -->
<context:component-scan base-package="com.xxx.xx" />
When I run application and access it, I got below exceptions in console:
[WARN]18:43:06(PathMatchingResourcePatternResolver.java:530) - Cannot
search for matching files underneath URL
[bundleresource://873.fwk-1377360156/com/xxx/xx/] because it does not
correspond to a directory in the file system
java.io.FileNotFoundException: URL
[bundleresource://873.fwk-1377360156/com/xxx/xx/] cannot be resolved to
absolute file path because it does not reside in the file system:

Hi, I've just replied to your what I believe is your equivalent post on the
WASdev forum.
https://www.ibm.com/developerworks/community/forums/html/topic?id=fead994c-1d1c-49e8-9eb5-9b5fe2b55c93&ps=25
I hope this helps.
Regards, Graham.
