Log4j2 UDP socket configure error. Class not found org.apache.logging.log4j.core.impl.Log4jLogEvent$LogEventProxy

Hi,

I'm trying to use UDP server to log my messages. For this I use LOG4J2.
But I got below error in the server side.

ClassNotFoundException Error : java.lang.ClassNotFoundException:
org.apache.logging.log4j.core.impl.Log4jLogEvent$LogEventProxy


Below is my server side code.


ByteArrayInputStream bis = new ByteArrayInputStream(packet.getData());
ObjectInputStream obj = new ObjectInputStream(bis);
LogEvent logEvent = (LogEvent) obj.readObject();

System.out.println(logEvent.toString());


Below is my pom.xml file dependency.

<dependency>
<groupId>org.apache.logging.log4j</groupId>
<artifactId>log4j-api</artifactId>
<version>2.0-beta4</version>
</dependency>
<dependency>
<groupId>org.apache.logging.log4j</groupId>
<artifactId>log4j-core</artifactId>
<version>2.0-beta4</version>
</dependency>




Thanks in advance,
Imesh

Imesh,
Does the server-side code (the process that is receiving UDP messages) have both the log4j-api and the log4j-core jar files in the classpath?

I've attached your files to the Jira ticket. Would you mind if we follow up on this issue by commenting on Jira?

Hi Gary,

This is happening in while running. In my TCP server class. below is snipt.

private void someMethod() throws IOException{
             DatagramSocket socket = new DatagramSocket(9092);


             byte[] buf = new byte[100000];
             DatagramPacket packet = new DatagramPacket(buf, buf.length);

             socket.receive(packet);

             ReadPacket(packet.getData());

}
public static String ReadPacket(byte[] recievedPakets){


         String retvals = "";
         ByteArrayInputStream bis = new 
ByteArrayInputStream(recievedPakets);

         LogEvent logEvent = null;
         ObjectInputStream obj = null;
         try {

             bis = new ByteArrayInputStream(recievedPakets);
             obj = new ObjectInputStream(bis);
             logEvent = (LogEvent) obj.readObject();
             System.out.println(logEvent.toString());


         } catch (IOException e1) {
             System.out.println(" IOException Error : "+e1);
             e1.printStackTrace();
         } catch (ClassNotFoundException e1) {
             System.out.println(" ClassNotFoundException Error : "+e1);
             e1.printStackTrace();




         }finally{
             try {bis.close(); } catch (Exception e2) {}

         }

         return retvals;

     }




Thanks,
Imesh

Does the error happen from maven or your IDE?

Hi Imesh,

I'll take a look, thank you. 
I'll attach the files to the Jira when I get home.

About Jira, I think anyone can create an account. Maybe for next time... :-)

Imesh,

It is hard to see what could be the problem based on your description.
I created this JIRA ticket for the issue you describe:
https://issues.apache.org/jira/browse/LOG4J2-228


Would it be possible for you to attach a test program that demonstrates the issue to that JIRA ticket?

Kind regards,
Remko
