[jboss-jira] [JBoss JIRA] Commented: (JBVFS-109) Trying to access all classpath resources from a web application fails due to VFS errors

[Marius Bogoevici (JIRA)]

    [ https://jira.jboss.org/jira/browse/JBVFS-109?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12473608#action_12473608 ] 

Marius Bogoevici commented on JBVFS-109:
----------------------------------------

Naresh, 

for a solution to the classpath scanning problem, please refer to http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4239767#4239767

This issue is strictly addressing the incorrect internal VFS behaviour and has nothing to do with Spring per se.

> The error has been triggered by using classpath scanning in Spring, but can be reproduced independently.
> The code in the servlet listed below does virtually the same thing as the VFSResourcePatternResolver:
> public class BasicServlet extends HttpServlet{
>     @Override
>     protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
>         ClassLoader classLoader = Thread.currentThread().getContextClassLoader();
>         Enumeration<URL> urls = classLoader.getResources("");
>         StringBuffer buffer = new StringBuffer();
>         while (urls.hasMoreElements()) {
>             URL url = urls.nextElement();
>             VirtualFile file = VFS.getRoot(url);
>             buffer.append(file.getPathName() + "\n");
>         }
>         new PrintWriter(resp.getOutputStream()).println(buffer.toString());
>     }
> }
> Trying to access the servlet results in an error when one URL is converted to a VirtualFile by VFS.getRoot(), and here is the resulting exception. The URL that triggers the error differs if the test is repeated.
