-----------------------------------------------------------------------------------------------
Key: WINK-187
URL: https://issues.apache.org/jira/browse/WINK-187
Project: Wink
Issue Type: Bug
Components: Common
Affects Versions: 0.2
Environment: IBM Lotus Expeditor's Web Container - LWI. It is loaded in Equinox OSGi framework.
Reporter: Kaloyan Kolev
Priority: Minor
Fix For: 0.2
It seems like the org.apache.wink.common.internal.utils.FileLoader is trying to locate the META-INF/wink-default.properties file using an OSGi class loader.
This is the exception that is being produced:

Michael Elman commented on WINK-187:
------------------------------------
I'm not really familiar with Equinox, but as far as I understand Equinox blocks some JDK functionality and your proposed patch is a workaround.
I see at least one problem with your patch: it cannot be used to load multiple resources with the same name, and actually today I enhanced FileLoader with this ability. See [WINK-181].
Pay attention that Wink first uses the classloader from the Thread.currentThread().getContextClassLoader(). This was done to allow changing the classloader by the external code.
Can it be a solution for you?

[jira] Commented: (WINK-187)
org.apache.wink.common.internal.utils.FileLoader is not able to open a
stream to existing File.
Posted by "Kaloyan Kolev (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/WINK-187?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12756046#action_12756046 ]
Kaloyan Kolev commented on WINK-187:
------------------------------------
The problem is not related to OSGi, but to the way we mangle the URI identifier. Here is the problematic code in method :
{code}
public static InputStream loadFileAsStream(String fileName) throws FileNotFoundException {
...
// decode any escaped sequences such as <space> which is %20 in
// URL
URI uri = url.toURI();
String path = uri.getSchemeSpecificPart();
url = new URL(url.getProtocol(), null, path);
...
}
{code}
As you can see the schema-specific-part is treated as a regular path which it is not. This violates the URI specification. For more details please refer to the URI specification here http://www.ietf.org/rfc/rfc2396.txt
My suggestion is simply to avoid dealing with URLs when that is not required. At this point the external code has requested an InputStream object and since we have an API for accessing that through the classloaders we could return that directly. My suggestion also considers the context classloader set on the thread. As you can see in the bellow code you have the same functionality as before but this way you do one step less to get the same result.
These are new methods that need to be added:
{code}
/**
* open the specified resource using class loaders
*
* @param filename
* the name of the resource
* @return the resource as {@link InputStream} if found
* @throws FileNotFoundException
* if the resource was not found
*/
private static InputStream openResourceUsingClassLoaders(String filename) throws FileNotFoundException {
logger.debug("Searching for {} using thread context classloader.", filename);
ClassLoader classLoader = Thread.currentThread().getContextClassLoader();
InputStream is = openResourceUsingClassLoader(classLoader, filename);
if (is == null) {
logger.debug("Searching for {} using current classloader.", filename);
classLoader = FileLoader.class.getClassLoader();
is = openResourceUsingClassLoader(classLoader, filename);
if (is == null) {
logger.debug("Searching for {} using system classloader.", filename);
is = ClassLoader.getSystemResourceAsStream(filename);
if (is == null) {
// well, the last attempt has failed! throw
// FileNotFoundException
logger.error("Failed to open resource using classloaders");

------------------------------------
I have not tried that but as you pointed I have used already indirectly. I will give it a shot and get back to you.
I will remove the following code from the original method and try it:
{code}
// file is not a normal file, try to find it using classloaders
URL url = loadFileUsingClassLoaders(fileName);
try {
// decode any escaped sequences such as <space> which is %20 in
// URL
URI uri = url.toURI();
String path = uri.getSchemeSpecificPart();
url = new URL(url.getProtocol(), null, path);
} catch (IOException e) {
logger.error(e.getMessage(), e);
throw new FileNotFoundException(fileName);
} catch (URISyntaxException e) {
// do nothing, but return the real (!) url
}

{code}
was added...
Regarding doing "one step less":
this is code of getResourceAsStream in SUN's JDK:
{code}
public InputStream getResourceAsStream(String name) {
URL url = getResource(name);
try {
return url != null ? url.openStream() : null;
} catch (IOException e) {
return null;
}
}
{code}
so it's exactly same steps.
May be we can remove the escaping section, so it should work for you.
Did you try this?

[jira] Issue Comment Edited: (WINK-187)
org.apache.wink.common.internal.utils.FileLoader is not able to open a
stream to existing File.
Posted by "Kaloyan Kolev (JIRA)" <ji...@apache.org>.

I removed the following code from the original version and the files were successfully found and opened.
{code}
// file is not a normal file, try to find it using classloaders
URL url = loadFileUsingClassLoaders(fileName);
try {
// decode any escaped sequences such as <space> which is %20 in
// URL
URI uri = url.toURI();
String path = uri.getSchemeSpecificPart();
url = new URL(url.getProtocol(), null, path);
} catch (IOException e) {
logger.error(e.getMessage(), e);
throw new FileNotFoundException(fileName);
} catch (URISyntaxException e) {
// do nothing, but return the real (!) url
}
{code}
was (Author: kkolev):
I have not tried that but as you pointed I have used already indirectly. I will give it a shot and get back to you.
I will remove the following code from the original method and try it:
{code}
// file is not a normal file, try to find it using classloaders
URL url = loadFileUsingClassLoaders(fileName);
try {
// decode any escaped sequences such as <space> which is %20 in
// URL
URI uri = url.toURI();
String path = uri.getSchemeSpecificPart();
url = new URL(url.getProtocol(), null, path);
} catch (IOException e) {
logger.error(e.getMessage(), e);
throw new FileNotFoundException(fileName);
} catch (URISyntaxException e) {
// do nothing, but return the real (!) url
}
{code}

Description:
It seems like the org.apache.wink.common.internal.utils.FileLoader is trying to locate the META-INF/wink-default.properties file using an OSGi class loader.
This is the exception that is being produced:
