I am super stuck with trying to run my program thats written for using activemq as a jms provider. I dont know what else to try or what documentation to read. Currently my project is in maven. But to me it doesnt matter whether it runs with or without maven.
I execute mvn clean compile and it builds. Then I am in the folder my pom.xml resides in and execute java -cp target/classes task3.broker.JmsBrokerServer
I have 3 packages task3.broker , task3.client and task3.common. And I wanna run this file.
I get the follwing error (translated)
Error: Main class task3.broker.JmsBrokerServer can not be initialized
Cause: java.lang.NoClassDefFoundError: javax/jms/JMSException
If there is any information you'd need in order to help me just let me know, I will provide it as soon and as precise as I can. Thanks in advance !!
