• What is the cause and solution for SAP error message SVMCRT_SESSION_MGM001 - The constructor of the store implementation class must be declared public ?

  The SAP error message SVMCRT_SESSION_MGM001 indicates that there is an issue with the constructor of a store implementation class in the context of SAP's Session Management. Specifically, the error states that the constructor must be declared as public.
  Cause:
  This error typically arises when you are trying to implement a custom store for session management in SAP, and the constructor of your store implementation class is not accessible. In Java, if a constructor is not declared as public, it cannot be instantiated outside of its own class or package, which leads to this error when the SAP framework attempts to create an instance of your store implementation.
  Solution:
  To resolve this error, you need to ensure that the constructor of your store implementation class is declared as public. Here’s how you can do that:
  
  
  Locate the Store Implementation Class: Find the Java class that implements the store for session management.
  
  
  Modify the Constructor: Change the constructor's access modifier to public. For example, if your class looks like this:
  public class MySessionStore {
      MySessionStore() { // This is package-private
          // Constructor logic
      }
  }
  You should change it to:
  public class MySessionStore {
      public MySessionStore() { // Now it's public
          // Constructor logic
      }
  }
  
  
  Recompile and Deploy: After making the change, recompile your Java class and redeploy it to your SAP environment.
  
  
  Related Information:
  
  Session Management in SAP: SAP uses session management to handle user sessions, and custom implementations may be required for specific use cases.
  Java Access Modifiers: Understanding Java access modifiers (public, private, protected, and package-private) is crucial for ensuring that classes and their members are accessible as intended.
  SAP Documentation: Refer to the official SAP documentation for more details on session management and custom implementations, as well as best practices for coding in the SAP environment.
  
  If you continue to experience issues after making the constructor public, ensure that there are no other underlying problems with your implementation or configuration.
