Cause:

JDK installed in a 64-bit system is 64-bit (virtual machines, that is, 64-bit). According to the error reported, a 64-bit virtual machine cannot be loaded in a 64-bit system, it can only load 32 bits.

Solution:

1. Download a 32-bit replacement http://www.apache.org/dist/tomcat/tomcat-connectors/native/1.1.31/binaries/

2. decompress the downloaded file and find the tcnative-1.dll file under the x64 folder

3. Replace the tcnative-1.dll file under the bin folder in Tomcat
