[Solved]-Imported jar files creates empty packages-eclipse

if you're using mq 7, check its documentation here. there was some stuff going on about deprecation of com.ibm.mq.mqc and, depending on the version you use, that class was replaced by com.ibm.mq.constants.mqconstants. like this one, there are other cases.

in fact com.ibm.mq only contains the exception mqexception, so you won't find any classes there. i suggest you check the version you're using and dig a little deeper into the docs, as a first step.
