Starting Confluence (Data Center) on local results in blank page.
Getting 302 response for the (http://localhost:1990/confluence).
Getting 304 for the same api calls after that [this might be due to browser cache].

also getting"Dummy file to trigger action handling from a welcome file in Tomcat 6" in api response.
And API call type says redirected.

confluence version - 9.2.0
Java jdk version - 21 (tried with liberica jdk 21, and Eclipse temurin jdk 21)
os - macOS (sonoma)
browser - chrome 131 [tried hitting api from other browsers but no luck]

No logs in catalina.out.
Never got any error on terminal from where I ran the application.


is there any configuration i had to do before staring it???

Hello @Dattatray Tamke ,

the behavior you are describing sounds a lot like a java compatibility issue covered in morte detail here:

However as covered in the KB article that would be triggered via jdk11 where you noted being on v21

To verify what java version is getting picked up can you check the "catalina.out" log file to see if you can locate a an error noting:

Wrong JVM version detected! 

Regards,
Earl

Hi @Earl McCutcheon 

I am just getting this issue for confluence version 9.2.0 and 9.2.0 should work with jdk 21 as the version uses this only.

I dont have any logs in catalina.out complete blank.

Can you suggest any other way for this??

Hi @Dattatray Tamke ,

If the logs are completely blank thats an indication of a file write permissions issue as described in the following document Noting this one is for a single confluence log but highlights why the logs would not be writing:

If there is a write issue there would be a lot of underlying startup issues which is a likely culprit of the overall issue, so next steps I would suggest that you check out the following documentation that discusses the overall file permission requirements in a bit more detail and steps to correct:

Regards,
Earl
