SAXParserFactory issue while deploying 5.2.7.8 with tomcat 8.5

ariesb2b — Thu, 17 Jun 2021 17:23:41 GMT

Our application (ACS 5.2.7.8) is working fine with tomcat 7.x but when i try to deploy the same on tomcat 8.5 i get following error.

My enviroment:

JVM Version: 1.8.0_192-b12( on linux RHEL 7.x)

i have logback-classic-1.1.9.jar, logback-core-1.1.9.jar and slf4j-api-1.7.21.jar in tomcat/lib and WEB-INF/lib both places. Do i need to update anything else here for this setup to work?

Hi @ariesb2b

Just to be clear, Enterprise version 5.2.x is not supported on Tomcat 8.5. In this one case, based on specific circumstances, it was agreed to temporarily support this customer’s instance on Tomcat 8.5 while they prepared to upgrade to 6.2.x.
