Hi All,
I'm using this community plugin for Notifications:
https://docs.geoserver.org/stable/en/user/community/notification/index.html#notification-community-module-plugin-documentation
I was able to make it work with RabbitMQ as fanout,
but I'm experiencing an issue just as I want messages to be sent to a topic
on *ActiveMQ*.
This XML setting works well with RabbitMQ and sends a message to queue
"changes" on "exchange1"
<notificator>
<queueSize>1000</queueSize>
<processorThreads>10</processorThreads>
<messageFilter>type='Data'</messageFilter>
<genericProcessor>
<fanoutSender>
<username>guest</username>
<password>guest</password>
<host>localhost</host>
<port>5672</port>
<virtualHost>/</virtualHost>
<exchangeName>exchange1</exchangeName>
<routingKey>changes</routingKey>
</fanoutSender>
</genericProcessor></notificator>
Instead for *Apache ActiveMQ *I'm trying to make geoserver send
message to a topic named "topic.geoserver", so I replaced
<fanoutSender> with <*topicSender*> and I filled others like this:
<notificator>
<queueSize>1000</queueSize>
<processorThreads>10</processorThreads>
<messageFilter>type='Data'</messageFilter>
<genericProcessor>
<*topicSender*>
<username>admin</username>
<password>admin</password>
<host>localhost</host>
<port>5672</port>
<virtualHost>/</virtualHost>
<exchangeName>topic.geoserver</exchangeName>
<routingKey>topic.geoserver</routingKey>
</*topicSender*>
</genericProcessor>
</notificator>
But it doesn't send message to AMQP server,
it raises an error as follows:
24 nov 11:41:15 ERROR [geoserver.notification] -
java.lang.NullPointerException
at
org.geoserver.notification.common.DefaultNotificationProcessor.process(DefaultNotificationProcessor.java:38)

at java.base/java.lang.Thread.run(Thread.java:829)
Probably I'm not setting the XML in the correct way. Can you help me
to solve this issue?
Thanx very much,
Regards,
Gianni
