Note the full stack trace of the root cause is available in the Apache Tomcat/6.0.20 logs.

--------------------------------------------------------------------------------

Apache Tomcat/6.0.20

Symptom: You can obtain the business logic bean in the main method to query the database. However, you can call the business logic to query the database by passing parameters to the action on the webpage,
This exception prompt appears.
Cause: there is a conflict between the two jar packages in the project: antlr-2.7.6.jar and anltr-2.7.2.jar. Remove the anltr-2.7.2.jar package.
The reason for smooth execution in the main method is that the anlr. jar package is dependent on struts2. If you do not pass parameters on a webpage, you do not need them, so they can be executed smoothly.
