Issue while upgrading from AEM 6.3 TO 6.5

[#1]

Hi,

We are doing AEM upgrade from version 6.3 to 6.5. Also moving from Jboss to Tomcat.(AEM 6.5 author is on Tomcat). While starting up the server, we are getting this exception:

Any help would be appreciated.

Just to add we tried this : https://experienceleaguecommunities.adobe.com/t5/adobe-experience-manager/aem-6-2-and-java-1-8/qaq-p...

We couldn't find any such property in sling.properties.

We have changed tomcat attribute: strictServletCompliance as false and that has resolved the issue with javax.servlet version>=3.1.0. We are using javax.servlet version:3.0 now on same Tomcat instance.

[Jörg_Hoh · Accepted solution]

Great, that you got it resolved. Strange behavior anyway, because you are working on a fully supported platform.

[Shallu_Rohilla]

Hi,

the problem is:

(&(osgi.wiring.package=javax.servlet)(version>=3.1.0)(!(version>=4.0.0)))]

what version of Tomcat do you use? 

From what I see in the specification at https://tomcat.apache.org/whichversion.html, only Tomcat 8.0.x and 8.5 are eligible, as any newer version brings javax.servlet 4.0 specification (which is not supported according to this version range). And according to the support matrix at https://helpx.adobe.com/experience-manager/6-3/sites/deploying/using/technical-requirements.html only Tomcat 8.5 is supported.

[Shallu_Rohilla]

But we are following Adobe documentation which says tomcat 8.5.x. As we have deployed version 6.5. https://docs.adobe.com/content/help/en/experience-manager-65/deploying/introduction/technical-requir...

Hi Jorg, We are using Tomcat 8.5.41 version and AEM 6.3 was running fine on this instance before upgrade

[Shallu_Rohilla]

So, our current AEM version is 6.5 and tomcat version is 8.5.41 which should be supported as per AEM documentation.

[Jörg_Hoh]

Can you please paste a screenshot of the details of the Bundle "Apache Sling Startup Filter" from your 6.3 environment?

Hi @Shallu_Rohilla 

Can you try installing the latest service pack of AEM 6.5? 

I've recently upgraded AEM 6.3 to AEM 6.5.4 and didn't face any such issue.

Also please confirm:

• Are you doing an in-place upgrade or moving the content over packages?
• is this issue happening after installing the your custom code?

Hi Mate, 

Please find below responses to your questions.

Can you try installing the latest service pack of AEM 6.5? I've recently upgraded AEM 6.3 to AEM 6.5.4 and didn't face any such issue.

- We are not able to access CRX/de, System console or package manager We are getting HTTP Status 503 – Service Unavailable

Also please confirm: Are you doing an in-place upgrade or moving the content over packages?

- This is inplace upgrade

is this issue happening after installing the your custom code?

- We already have all the code in this environment. This is running performance testing environment

Issue occurrence: After upgrade steps, while instance is starting up we could see this error.

We have followed the steps as per: https://docs.adobe.com/content/help/en/experience-manager-65/deploying/upgrading/app-server-upgrade....

Hi @gspatil11 @Shallu_Rohilla 

You can try the below step to add a service pack.

• Stop your instance.
• Download the latest service pack.
• Create a folder named “install” inside the “crx-quickstart” folder [this is folder is present in the same location of jar file].
• Copy the SP zip file downloaded in Step 2 inside the install folder. [Please create an install folder if it is not present]
• Start AEM

Regards,

Arpit

Hi Arpit, This doesnt looks like issue with Service Pack, i found another link : https://helpx.adobe.com/experience-manager/6-3/sites/developing/using/reference-materials/javadoc/or..., do you have any idea?

https://docplayer.net/63840222-Deep-dive-into-the-aem-upgrade-process-part-1-aem-itself-bertrand-pri...

For us issue is 

Sling startup filter + disabler cause 503 status during startup
