Dependencies on extensions functionality
Hi,
I'm using Tomcat 7.0.23 on Windows.
I have a web application that specifies in the Manifest that wants to use
an extension.
I specify "catalina.ext.dirs" to point to the directory where I placed my
extensions jar files.
Unfortunately when I request my application I'm receiving
"ClassNotFoundException".
I verified that
ExtensionValidator.validateApplication() succeeded to find the extension
jar file.
What could be the problem? May be I'm missing some configuration?
Thanks in advance.
Regards
Violeta

It appears to be first documented in Tomcat for Servlet 2.3.

I'm curious, what kind of extension are you creating and what for?

Re: Dependencies on extensions functionality

Hi,
The Dependencies on Extensions mechanism is described in Servlet Spec 3.0 -
chapter 10.7.1.
In the web application's Manifest file one should describe the following:
Extension-List: <extension>
<extension>-Extension-Name: <name>
<extension>-Specification-Version: <version>
<extension>-Implementation-Version: <version>
<extension>-Implementation-Vendor-Id: <vendor>
in the jar file's Manifest (this is the extension), one should specify:
Extension-Name: <name>
Specification-Version: <version>
Implementation-Version: <version>
Implementation-Vendor-Id: <vendor>
So from the spec we have "The container must provide a directory for these
libraries. The files placed within this directory must be available across
all Web applications. The location of this directory is container-specific.
The class loader the servlet container uses for loading these library files
must be the same for all Web applications within the same JVM. This class
loader instance must be somewhere in the chain of parent class loaders of
the Web application class loader."
>From Tomcat sources I can see that while starting web app context
(StandardContext.startInternal()) the extensions are checked for
availability (ExtensionValidator.validateApplication). I can see again in
the ExtensionValidator that "catalina.ext.dirs" also is scanned while
scanning for container level extensions. Unfortunately I cannot find a
place where this extensions are made available for web applications.

Violeta

How does it do that?

How is that property processed?

No idea. What are extensions?
How is that JAR file added to the/a classloader?

Fair enough.
I actually would prefer that people attach things (and keep them small)
rather than posting a link to dropbox or whatever. Attachments go into
the archives and are readable at a later date. Stuff in dropbox
eventually expires and so someone looking through the archives might
not be able to see some important information (e.g. "I posted my
working configuration here: [dropbox link]. Thanks for the help!").

Re: Dependencies on extensions functionality
Posted by Violeta Georgieva <mi...@gmail.com>.
Hi,
Here is the bug that I created:
https://issues.apache.org/bugzilla/show_bug.cgi?id=52607
I didn't find "catalina.ext.dirs" property in the documentation.
I just attached the debugger and checked the sources while executing the
scenario ;-)
Thanks and Regards
Violeta

Good question. Please file a bug in Bugzilla. You can include a link
to this thread.
Searching the sources for "catalina.ext.dirs" it is mentioned in
ExtensionValidator.java source only. It is never mentioned in User
Guide or Configuration Reference.
It should be added to docs/config/systemprops.html and maybe mentioned
in docs/class-loader-howto.html
Searching just for "ext.dirs" you see one more place,
AntCompiler.java, that uses just "java.ext.dirs" and not catalina one.
So maybe you had to redefine the "java.ext.dirs" property, like
catalina.sh does with "java.endorsed.dirs".
I wonder how did you found this "catalina.ext.dirs" property. From Javadoc?

You can. You can reconfigure classpath in the conf/catalina.properties file.

Gotcha: so, the validation works properly, but the catalina.ext.dirs
doesn't actually get added to the classpath. Oops.

Actually as I wrote in the mail with the scenario:
, when I do not specify the "catalina.ext.dirs", deployment fails

Yeah, I had never heard of it.
Also, the whole metadata-scanning thing seems totally unnecessary: the
webapp tries to load a class, and the ClassLoader figures it out. The
fact that the metadata exists doesn't really help much.
I haven't looked at the validation code, though, so it's possible that
the container is supposed to refuse to deploy the webapp if an
appropriate extension isn't available.
That obviously wasn't happening in Violeta's case because the
deployment succeeded but then she got a CNFE.

I see - in my experience this mechanism is rarely used in web
applications. Interesting.

I have existing applications that are moving to Tomcat from another
application server.
As "dependencies on extensions" is a standard mechanism for shared
libraries, they use it in order to be independent from the application
servers.

I was going to ask you why you were using it! So is your interest

It should work. (As per Konstantin's message)

Re: Dependencies on extensions functionality
Posted by Violeta Georgieva <mi...@gmail.com>.
Hi,
As I wrote I'm placing the extension jar in "C:\apache-tomcat-7.0.25\ext".
I tried the following: I specified "C:\apache-tomcat-7.0.25\lib" as value
for "catalina.ext.dirs" property and now the web application is working.
But then I have two questions:
- Do we need "catalina.ext.dirs" at all if we can use only Tomcat's
classpath dirs? Let's look through them instead of introducing additional
property.
- Does this mean that we can use only Tomcat's classpath dirs and we cannot
specify a custom directory for these extensions?
Thanks
Violeta

Hi,
Here is how one can reproduce the scenario:
1. Start Tomcat
2. Put attached war in webapps folder
3. In the console the following error message is printed:
INFO: Deploying web application archive
C:\apache-tomcat-7.0.25\webapps\test-web-app.war
Feb 4, 2012 10:41:44 PM org.apache.catalina.util.ExtensionValidator

extension [test-jar] not found.
Feb 4, 2012 10:41:44 PM org.apache.catalina.util.ExtensionValidator
validateManifestResources
INFO: ExtensionValidator[/test-web-app]: Failure to find [1] required
extension(s).

SEVERE: Error getConfigured
Feb 4, 2012 10:41:44 PM org.apache.catalina.core.StandardContext
startInternal
SEVERE: Context [/test-web-app] startup failed due to previous errors
4. Stop Tomcat
5. Create folder - C:\apache-tomcat-7.0.25\ext
6. Put the attached jar file in the folder created on step 5
7. Start Tomcat with additional VM argument
-Dcatalina.ext.dirs=C:/apache-tomcat-7.0.25/ext
8. This time the application is deployed successfully.
9. Request http://localhost:8080/test-web-app/TestServlet
10. Internal Server Error is returned with the following Exception:
java.lang.ClassNotFoundException: test.TestExtension
org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1701)
org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1546)
test.TestServlet.doGet(TestServlet.java:28)
javax.servlet.http.HttpServlet.service(HttpServlet.java:621)
javax.servlet.http.HttpServlet.service(HttpServlet.java:722)
I did not change any other Tomcat configuration so it is running with
defaults.
The scenario is that TestServlet (in war file) instantiates TestExtension
(in jar file, placed in the ext directory).

What is the value of the catalina.ext.dirs system property? Where did
you set it? Can you verify that it is set when the JVM actually starts?
What files are in the directory or directories specified by
catalina.ext.dir?
> Unfortunately when I request my application I'm receiving

What class cannot be found? Is it found in any of the JAR files you
have in your catalina.ext.dir (which is, of course, the whole point of
the feature)?

How did you verify this? Are there logs that suggest your JAR file is
being scanned? Please provide them.
> What could be the problem? May be I'm missing some configuration?
You might be, but you haven't provided any configuration to us, so we
don't know if you're missing something. Clearly, something is
misconfigured.
