and then deployment process ends with incomplete status. what should i do then? thx a lot.

It looks like you are missing oracle.dmt.op.re.base.Enum on your classpath, hence the:

java.lang.ClassNotFoundException: oracle.dmt.op.re.base.Enum$EnumType

Add ${ORACLE_HOME}/dmt/oputil.jar and/or ${ORACLE_HOME}/dmt/opreapi-batch.jar on your classpath (not sure which one contain the missing class but they are often used together anyway).

Then, rerun appc as the second error (with helpdesk_project.CaptchaServiceSingleton might be related to the first issue.

Seems can not found this class: java.lang.ClassNotFoundException: oracle.dmt.op.re.base.Enum$EnumType

Need to include above class also, you need to find a jar containing that class.
