I faced this same issue while installing Appian 22.2. I replaced the driver jar. It worked. Please refer to the below link for reference.

But 8.0.22 has vulnerability. How do we fix this

I had a similar issue when installing 21.2, with the error being mentioned in the tomcat log as:

Caused by: java.lang.ClassCastException: java.time.LocalDateTime cannot be cast to java.lang.String

This was solved by replacing the mysql-connector-java-8.0.25.jar in the repo/tomcat/apache-tomcat/bin with the 8.0.22 version.

For your issue, doing a similar replacement with an earlier version of the jar may fix it.

Hi, We are seeing the below issue while restarting the Appian server. Please let us know if you see any error similar to this.

The error is "Could not open JPA EntityManager for transaction; nested exception is java.lang.IllegalStateException: [jdbc/AppianDS] Error during schema migration"

So I'd suggest the following:

1. If on linux, use the JAVA shipped with the product and set the JAVA_HOME, PATH to point to it. Example:

export JAVA_HOME=/usr/local/appian/java

export PATH=$JAVA_HOME/bin:$PATH:

2. In the tomcatResources.xml file and /tomcat/apache-tomcat/conf/Catalina/localhost/suite.xml file make sure the datasource starts with the same resource name = /jdbc/AppianDS or whatever you've called your primary database.

The key is that the resource you choose 'jdbc/AppianDS' is consistent.

Note: You may well have decided to install the latest 20.3 release.
