To retrieve administered objects from a Java Naming and Directory Interface (JNDI) namespace, a JMS application must create an initial context and then use the lookup () method to retrieve the objects. Before an application can retrieve administered objects from a JNDI namespace, an administrator must first create the administered objects. The Apache HTTP Server is not written in Java, it does not use the log4j library, so it is not affected by CVE-2021-44228. Your log files are from the access log, they show people scanning for the log4j vulnerability. Apache itself is not written in Java and does not directly link the infamous Log4j library. It is particularilly safe from this.
