ServletContext.getResourceAsStream() problem?

[ko5tik]

Hi all,

I just discovered that ServletContext.getResourceAsStream()
can ( and does ) return resource from another webapp
( in my case velocity template through WebappResourceLoader )

I use freshly downloaded 3.2.3 without any changes.


Is this problem known? Somehow addressed? Any workarounds?

After planting various debug out int my WebappLoader, I just discovered that when I say ServletCcontext.getResource(String),
it's loaded via JNDI.

Here is java code fragment:

 for (int i=0; i < paths.length; i++)
 {
 try
 {
 System.err.println("checking path: " + paths);

 result = servletContext.getResourceAsStream(paths + name);

 /* exit the loop if we found the template */
 if (result != null)
 {
 System.err.println("found resource " + name + " at: " + servletContext.getResource(paths + name));
 break;
 }
 }
 catch (Exception e)
 {
 /* only save the first one for later throwing */
 if (exception == null)
 {
 exception = e;
 }
 }
 }

And here is the result:
11:41:13,568 ERROR [STDERR] checking path: /
11:41:13,571 ERROR [STDERR] found resource index.vm at: jndi:/localhost/unadmin/index.vm


From both webapps identical...


Is this problem known? Any workarounds? 3.2.0 worked better...

OK, Further investigation shows, that 2 independet web applications can share singleton instance of velocity.

How is this possible?
