The server is a RHEL with WebSphere 9.0.5.5 and java openjdk version "1.8.0_292"
The application is developed so it takes a message from a message queue and processes them. The message queue being used is IBM MQ 9.1.1.0. The application is taking the messages but not processing them correctly. The error is presenting on startup and also on execution.
Any guidance would be much valued.

It looks like the AppServer is using OpenJ9 while your application is being compiled with openjdk 1.8. Perhaps you are getting mismatch in the WAS ManagementFactory. Try "ps -fea" and check the jvm being used.

It was resolved by installing and configuring java JRE version 1.8 at Websphere execution level.

grails 1.1.1 will support java 1.7

Currently my application is running on grails 1.1.1 with java 1.6 on web sphere server. My application is working in old server with java 1.6.Recently server team upgrade the websphere server 8.5.5 and they asked us to deploy an ear with java 1.7. I have deployed the ear with java 1.7. now I am getting below error:

I have a few questions:
Grails 1.1.1 will support java 1.7?
if not do I need to upgrade grails?
What are all the steps to upgrade grails?
web sphere 8.5.5 will not support java 1.6?
to resolve this error what I need to check?
Do I need to update jars?
please find below jars which I am using in my application:
jar files

Going to try to answer as much as I can, but it's a best-effort since you're asking way too many questions in one post!
1 - Probably not. Grails 1.1.1 came out in 2009, and Java 1.7 came out in 2011, and was a major change over 1.6. You might be able to force them to work together, but you're going to struggle to find good information six (plus) years later.
2 - Yes.
3 - You can start here: http://docs.grails.org/1.2.0/ and go from there.
4 - See comment below. (Originally I said, but was wrong: IBM recommends Java 8 with WebSphere 8.)
5 - Probably not important, if you're upgrading everything anyway.
6 - Yes.

If the com.x.y.z is a 3rd party package, you'll need to set visibility of the third-party API packages in the Liberty server.xml to allow the application to access them.
Hopefully this documentation should help: https://www.ibm.com/support/knowledgecenter/en/SSEQTP_8.5.5/com.ibm.websphere.wlp.doc/ae/twlp_classloader_3p_apis.html

Struts 2.5 ClassNotFoundException Issue

I have a Struts problem. I'm upgrading an application from Struts 1.2.x to 2.5.8. I have a single war and multiple EJBs in a single EAR file deploying to WebSphere 8.5. Every time I try to access a simple hello world jsp via a Struts action, I get this stack trace in my browser:

I've verified that the required commons-fileupload jar is in the war and it's not in a shared library location that would cause namespace conflicts. Classloader setting is set to parent first, and due to the complexity of the project, I can't safely change it.
What do I need to do to get past this?
TIA
Alex

Looks like I spoke too soon. For some reason, my first search failed to turn up an older version of commons-fileupload in the AppServer/plugins folder. It appears this jar is being used by the app server, and with the parent first classloading in use, there's a class collision taking place. So now I have to figure out how to get around that, but the original problem has been solved.

As long as the classes in your commons-fileupload jar have no dependencies on your application or WAR classes, you can deploy this jar as an isolated shared library and associate it to your application or WAR, whichever has the dependency on the jar. The classloading semantics for isolated shared libraries are described in topic "Isolating open source packages" in the WebSphere Application Server Knowledge Center for versions 8.5.5 and 9.0.
Isolating open source packages:
https://www.ibm.com/support/knowledgecenter/SSAW57_8.5.5/com.ibm.websphere.nd.doc/ae/welc6tech_opensource_isolate.html
If you are using a recent version of 8.5.5, you might also try always-protected packages, which is also described in "Isolating open source packages". Note that always-protected packages can impact every application running on the application server.

I modified the lib of the downloaded solr.war. On the top of the jars already present in the solr.war/WEB-INF/lib, I added an additional set of jars from the downloaded solr package
All the jars from \solr-4.10.2\solr-4.10.2\dist
All the jars from \solr-4.10.2\solr-4.10.2\dist\solrj-lib
All the jars from \solr-4.10.2\solr-4.10.2\example\lib\ext
Modified the application Class Loading to 'PARENT_LAST'.
Have been scratching my head for over 16 hours.
Even tried removing the all the slf4j*.jars from the solr.war\WEB-INF\lib but the same error persists.
Some help is highly solicited.

Finally was able to make SOLR up and running on Websphere 8.5.5
I have enumerated the different steps on my blog.
