IBM Message Broker Java API：java.lang.NoClassDefFoundError：com.ibm.mq.MQException

Question

I am trying to connect to a broker in Message Broker using ibm's java API: http://publib.boulder.ibm.com/infocenter/wmbhelp/v7r0m0/index.jsp?topic=%2Fcom.ibm.etools.mft.doc%2Fbe43410_.htm

I am trying to use the example provided at that link (I am using a broker,port and queue manager that I KNOW exists) and I get the following error:

Exception in thread "main" java.lang.NoClassDefFoundError: com.ibm.mq.MQException
    at java.lang.J9VMInternals.verifyImpl(Native Method)
    at java.lang.J9VMInternals.verify(J9VMInternals.java:72)

    at BarAdmin.connectToBroker(BarAdmin.java:197)
    at BarAdmin.main(BarAdmin.java:52)

Any ideas?

Answer 1

Yes, you're missing the JAR that contains com.ibm.mq.MQException at runtime or the version of the JAR you do have doesn't contain that class.

Find the JAR that contains that class and add it to your runtime CLASSPATH.

Answer 2

MQ安装目录包含一个名为java / lib的目录，其中包含您需要的所有jar。
