Hi,
I am working on a project where I receive data via OPC UA. I process the data
to get a unique OID for SNMP. Afterwards I send the OID to a PRTG Monitoring
System.
Right now, I send data with the Prosys OPC UA simulation server and try to
connect with camel. The connection to the server works but I get a Java
NullPointerException on class Subscription Manager.
The error message looks like that:
java.lang.NullPointerException: null
at
org.apache.camel.component.milo.client.internal.SubscriptionManager$Connected.lookupNamespace(SubscriptionManager.java:287)
~[camel-milo-2.24.2.jar:2.24.2]
at
org.apache.camel.component.milo.client.internal.SubscriptionManager$Connected.putSubscriptions(SubscriptionManager.java:168)
~[camel-milo-2.24.2.jar:2.24.2]
...
My route looks like that:
from("milo-client:opc.tcp://localhost:4048/example?method=RAW(ns=5;s=MyLevel)&allowedSecurityPolicies=None")
.bean("NotrufsaulenTransformation", "transformData")
.to("snmp://127.0.0.1:161?protocol=udp&type=POLL");
Is there anything wrong with my route or the connection to the OPC UA server?
I am using Apache Camel version 2.24.2 with Spring Boot Framework 2.1.7.
Thank you very much in advance for your help!
Best regards,
Stefan Lederer
