Keine Factory als Backup für javax.faces.lifecycle.LifecycleFactory gefunden

Does someone knows how this exception can be fixed?

I want to use mybatis under Liferay 7.4 and i am getting this exception which i dont understand how to fix this or what is the main problem.

I would really appreciate any help.

I use Liferay 7.4, Java Server Faces 2.2, Mybatis 3.5.11, Mysql Conector 8.0.30 and Tomcat 9.0.56

This is the code being used:

private void ermittleTabellePersonsMitMybatisMitJNDI() {
        
        Thread thread = Thread.currentThread();

        // Get the thread's class loader. You'll reinstate it after using
        // the data source you look up using JNDI
        ClassLoader origLoader = thread.getContextClassLoader();

        // get the shielded class loader
        ClassLoader shieldedClassLoader = PortalClassLoaderUtil.getClassLoader();

        // get the webapp class loader from it
        ClassLoader webappClassLoader = shieldedClassLoader.getClass().getClassLoader();

        // Set webapp class loader on the thread
        thread.setContextClassLoader(webappClassLoader);
        DataSource datasource = null;
        InitialContext ctx = null;
        try {
            // Look up the data source and connect to it

             ctx = new InitialContext();
            datasource = (DataSource) ctx.lookup("java:comp/env/jdbc/testdatabase");
        } catch (NamingException ne) {
            ne.printStackTrace();
        }
        Properties props = new Properties();
//      props.put("data_source", datasource);
        props.put("initial_context", ctx);
        
        SqlSessionFactory sqlSessionFactory = null;
 
        try {
            Reader reader = Resources.getResourceAsReader("mybatis/config/SqlMapConfig.xml");
//          sqlSessionFactory = new SqlSessionFactoryBuilder().build(reader);
            sqlSessionFactory = new SqlSessionFactoryBuilder().build(reader, props);
        } catch (Exception e) {
            throw new RuntimeException("Fatal Error.  Cause: " + e, e);
        }
        abfrageStellen(sqlSessionFactory);
        thread.setContextClassLoader(origLoader);
    }

Here is the stacktrace:
