Weblogic 12C error java.lang.ClassNotFoundException: weblogic.jms.common.ResourceAllocationException - classpath

Question

I am facing this issue on my WebLogic 12 C, where an application gives this error
java.lang.ClassNotFoundException: weblogic.jms.common.ResourceAllocationException
The jar for the above class is wlclient.jar and it's not included in my application and I checked the managed server classpath ,it's not included there as well.
Funny thing is if I try adding the wlclient.jar in the setDomainEnv.sh as PRE_CLASSPATH hoping it will pick up the jar , I get the below error and managed server fails to start

Answer 1

I found if I add the classpath fully like below then the managed server gave error on startup
,
PRE_CLASSPATH="${DOMAIN_HOME}/lib/wlclient.jar"
export PRE_CLASSPATH
But if I add the classpath as below , then it worked.
PRE_CLASSPATH="${DOMAIN_HOME}/lib/"
export PRE_CLASSPATH
