Problem after upgrade TomCat

Hello,
I’had a xwiki 12.10.4 working correctly with TomCat 9.0.41 in a windows server.
I have to upgrade TomCat, and I uninstalled 9.0.41 and install new 9.0.98.

I’ve the access normally to localhost:8080 which displays TomCat page, but now when I enter my xwiki page on http://localhost:8080/xwiki I get a blank page.

I tried to debug, but I can’t find anything to help me understand the issue.
What can I do to get my xwiki to work again ?

Thank you

Running 15.10.x under TC 9.0.72 (Linux) without issues, if you want to try to downgrade.

Is there anything inside catalina.out?

The catalina.out is not beiing created on logs directory.
How can I reach to debug the issue, it enters on http://localhost:8080/xwiki/ but then only blank page.

I’d resolve this first.

Even with no webapps, the server log must be written, otherwise you can’t have an idea if things are going fine.

It was a problem on the user configuration of the TomCat Service.
It starts wiki now, but when arrives 100% it turns blank page on the XWikiLogin page

I finally reached to put it working.
The memory for java in the TomCat service had to be adjusted, and it worked after install TomCat with windows installer (perhaps some registries were updated, I don’t know !!)
