Hi,

Please share your hq-agent.sh file (..\bundles\agents-4.6.6\bin) or verify that you have all lines below. Looks like you dropped previous class path:

CLIENT_CLASSPATH="${AGENT_LIB}/hq-agent-core-4.6.6.jar"

CLIENT_CLASSPATH="${CLIENT_CLASSPATH}:${AGENT_LIB}"

CLIENT_CLASSPATH="${CLIENT_CLASSPATH}:${PDK_LIB}/hq-common-4.6.6.jar"

CLIENT_CLASSPATH="${CLIENT_CLASSPATH}:${PDK_LIB}/hq-util-4.6.6.jar"

CLIENT_CLASSPATH="${CLIENT_CLASSPATH}:${PDK_LIB}/hq-pdk-4.6.6.jar"

CLIENT_CLASSPATH="${CLIENT_CLASSPATH}:${PDK_LIB}/ant-1.7.1.jar"

CLIENT_CLASSPATH="${CLIENT_CLASSPATH}:${PDK_LIB}/commons-logging-1.0.4.jar"

CLIENT_CLASSPATH="${CLIENT_CLASSPATH}:${PDK_LIB}/log4j-1.2.14.jar"

CLIENT_CLASSPATH="${CLIENT_CLASSPATH}:${PDK_LIB}/sigar-1.6.6.jar"

CLIENT_CLASSPATH="${CLIENT_CLASSPATH}:${PDK_LIB}/httpclient-4.1.1.jar"

CLIENT_CLASSPATH="${CLIENT_CLASSPATH}:${PDK_LIB}/httpcore-4.1.jar"

CLIENT_CLASSPATH="${CLIENT_CLASSPATH}:${PDK_LIB}/spring-core-3.0.5.RELEASE.jar"

CLIENT_CLASSPATH="${CLIENT_CLASSPATH}:${AGENT_LIB}/hq-lather-4.6.6.jar"

CLIENT_CLASS=org.hyperic.hq.bizapp.agent.client.AgentClient

I recommend to revert original file  hq-agent.sh and add concatenate your JARs.

CLIENT_CLASSPATH="${CLIENT_CLASSPATH}:${AGENT_LIB}/wlfullclient.jar"

Good Luck
