Re: [Dev] We are getting some class not found issues intermittently

[Prasad Tissera]

We are still using Carbon 4.3.0 in IS. Since carbon-commons is still in
Carbon 4.3.0, there were issue building with 4.4.0-SNAPSHOT.

Regards,
Prasad.

 There has already been some work carried out related to this with :

 We will review and merge they PR to kernel along with above new changes.
 Kernel will not have any web socket related resources, but it will have
 tomcat level support for reading SPI's using OSGi approach. This will be an
 extension for tomcat.

 I think the root cause for this is same as what we found with spring
 bundle. Tomcat orbit also includes a SPI for 
 javax.servlet.ServletContainerInitializer. I have removed that
 from the above attached jar. Let me know the results of this with 
 IS.

 We do need this ServletContainerInitializer inside the tomcat

 Hi Sameera,

 Was this change applied to the 4.3.0 branch on git?. we are
 getting a similar random server not starting up issue. seems it is 
 the same
 reason. If this is not already allied can we get this added to 4.3.0
 branch. We are trying to fix integration test in greg and this random
 server hangup is causing a lot of time to be wasted.

 I think the root cause for this is same as what we found with spring
 bundle. Tomcat orbit also includes a SPI for 
 javax.servlet.ServletContainerInitializer. I have removed that from the
 above attached jar. Let me know the results of this with IS.

 Also currently IS-5.1.0 uses kernel 4.3.0 (tomcat_7.0.52-wso2v5). Can you
 test and confirm that the above issue is still there with kernel
 4.4.0-SNAPSHOT (Beta1) too? You may need to update the kernel dependency
 version of your distribution. If yes, we may need to do a tomcat orbit
 release.


We do need this ServletContainerInitializer inside the tomcat bundle to get
the websocket to work. If you think the cause of the above issue is this
SPI, then we have to find and fix the root cause.

Re: [Dev] We are getting some class not found issues intermittently

Not exactly. SPI's in OSGi environment are loaded using Thread Context
Classloader. See :
http://blog.osgi.org/2013/02/javautilserviceloader-in-osgi.html. We can
properly fix SPI's related issues with OSGi only with OSGi ServiceLoader
Mediator Specification (such as SPI Fly).

But to workaround this, I created a separate orbit for tomcat-websocket and
tested on AS. No issues popped up and the web socket sample seems to work
fine. This is by completely separating the web socket related
packages/resources from main tomcat orbit to a separate one. What more
should be tested with this?

Yea, with the use of SPI-Fly we can provide support for this. We actually
tested it out, and it works. We haven't introduced SPI-Fly to our platform
yet, hence the thought.

The websocket sample there uses the older Tomcat websocket API. I think we
are yet to update this sample to use the Websocket JSR. You can try this
out by installing the latest examples.war in tomcat.

@SupunM, did you find time to merge the new websocket samples to AS?

 Wasn't that we had same conversation in past about SPI-Fly, when
 Denuwanthi/Rajkumar doing their fast track project ?


Please refer following thread[1], during a review with Azeez we decided to
ship  SPI-Fly with Carbon/AS.

[1] - Shipping Aries SPI Fly in AS (was: ServletContainerInitializer for
AS)

Thanks !


 @SupunM, did you find time to merge the new websocket samples to AS?


 It's Ok to have samples but I think adding automation test cases for
 WebSockets and custom ServletContainerInitializers should get high
 priority.

 Thanks !

 I think the root cause for this is same as what we found with spring
 bundle. Tomcat orbit also includes a SPI for 
 javax.servlet.ServletContainerInitializer. I have removed that
 from the above attached jar. Let me know the results of this with IS.

 Also currently IS-5.1.0 uses kernel 4.3.0 (tomcat_7.0.52-wso2v5).
 Can you test and confirm that the above issue is still there with kernel
 4.4.0-SNAPSHOT (Beta1) too? You may need to update the kernel dependency
 version of your distribution. If yes, we may need to do a tomcat orbit
 release.


 We do need this ServletContainerInitializer inside the tomcat bundle
 to get the websocket to work. If you think the cause of the above issue 
 is
 this SPI, then we have to find and fix the root cause.

 Please refer following thread[1], during a review with Azeez we decided to

Oh yes, for a mail I sent. :-)

We can do this then!

 Thanks !


 @SupunM, did you find time to merge the new websocket samples to AS?


 It's Ok to have samples but I think adding automation test cases for
 WebSockets and custom ServletContainerInitializers should get high
 priority.



Yep.. +1.

 But to workaround this, I created a separate orbit for tomcat-websocket

https://wso2.org/jira/browse/CARBON-14864 is actually fixed with the given
fix. This issue seems not related to spring upgrade. You can confirm this
by downgrading the version or removing the spring bundle from carbon
runtime and check. We could still see the same startup/webapp deployment
error. This seems to a typical OSGi class loading issue.

Need to have a another deep look and see.

Although removing the jar fixed this issue, it will break the cause it was
originally added for right. Do we have a solution/workaround for that?

 Can you try to reproduce by removing the following jar from patch0009?

 repository/components/patches/patch0009/spring.framework_3.1.0.wso2v1.jar

 Thanks,
 Sameera.

Re: [Dev] We are getting some class not found issues intermittently

[Kasun Gajasinghe]

Hi,

Good catch Sameera. It seems that this issue has occurred since the spring
framework bundle in patch0009 includes a Service-Provider-Interface for
javax.servlet.ServletContainerInitializer. So, I have removed the
META-INF/services/javax.servlet.ServletContainerInitializer from spring
framework bundle, and tested in the AM pack provided by Ratha. I couldn't
re-produce it so far. I have added this file and several other config files
(META-INF/{spring.schemas, spring.handlers} etc.) to spring framework in
patch0009 to fix some issues in AS.

Since you need to provide packs to QA, I will remove this particular file
from spring framework bundle. @Ratha, it would be great if you can test
this out. You will have to do following step.

1. Remove the file
META-INF/services/javax.servlet.ServletContainerInitializer from
spring-framework bundle in patch0009
2. Restart the server

Thanks,
KasunG

Re: [Dev] We are getting some class not found issues intermittently

[Sameera Jayasoma]

Hi Ratha,

Here is how I found the culprit. :)

First I wanted to make sure that this issue occurs due to changes done to
the platform or to the kernel. To verify this I installed all the patches
from patch0001 to patch0009 to a Carbon kernel instance. But when I start
the kernel I got a Spring related class loading issue. Then I removed
patch0009 from the AM pack, but I couldn't reproduce the error. From these
steps I got a good observations to believe that patch0009 contains the root
cause of this issue.

Since I got a spring related error earlier, I removed the spring bundle
from patch0009 and tested in kernel instance as well as in an AM instance.
I couldn't reproduce the error.

Thanks,
Sameera.

 Hi all;

 It looks like webapps depend on OSGI bundles and when webapps get
 deployed, OSGi bundles are not active which causes webapp deployment
 failure issues..These webapps currently include Oauth+jaggery webapps.
 Please fix this issue at webapp deployer or in the webapps.

 At the same time  please check, what causes the *java.lang.*
 *ClassNotFoundException: org.wso2.carbon.tomcat.ext.*
 *servlet.DelegationServlet* issue..


 Thanks.

Hi all;

It looks like webapps depend on OSGI bundles and when webapps get deployed,
OSGi bundles are not active which causes webapp deployment failure
issues..These webapps currently include Oauth+jaggery webapps.
Please fix this issue at webapp deployer or in the webapps.

At the same time  please check, what causes the *java.lang.*
*ClassNotFoundException: org.wso2.carbon.tomcat.ext.*
*servlet.DelegationServlet* issue..
