I created a persistence entity and added mapping content in the *.hbm.xml,then I got the errors below while saving the entity which my new added in my application.

Code:
[6/29/11 11:03:23:143 CST] 0000005f SystemOut     O 11:03:23,134 [WebContainer : 0] ERROR ExceptionHandler : Exception: Unknown entity: com.ibm.cdl.scst.domain.processdata.SystemSunsetProcessData; nested exception is org.hibernate.MappingException: Unknown entity: com.ibm.cdl.scst.domain.processdata.SystemSunsetProcessData

Here is the entity:

   private String evidenceFileName;

   public SystemSunsetProcessData() {
   }

   public String getEvidenceFilePath() {
      return this.evidenceFilePath;
   }

   public void setEvidenceFilePath(String evidenceFilePath) {
      this.evidenceFilePath = evidenceFilePath;
   }

   public String getRealEvidenceFileName() {
      if (StringUtil.isEmpty(this.evidenceFilePath)) {
         return null;
      }

      return FileUtil.getRealFilePath(this.evidenceFilePath, Constant.FileCategory.SystemRemoval);
   }

   public int hashCode() {
      final int prime = getClass().hashCode();
      int result = 1;
      result = prime * result + id;
      return result;
   }

   public boolean equals(Object obj) {
      if (this == obj)
         return true;
      if (obj == null)
         return false;
      if (getClass() != obj.getClass())
         return false;
      final SystemSunsetProcessData other = (SystemSunsetProcessData) obj;
      if (id != other.id)
         return false;
      return true;
   }

}

Note:I doubt that ProcessData.hbm.xml doesn't work.In order to test,I delete the ProcessData.hbm.xml from my application.However,i was surprised that the original entity 'ConfidentialChangeProcessData' saving is success but my new added was still facing the same errors 'org.springframework.orm.hibernate3.HibernateSystemException'.
So I can't understand why the original entity was still success without ProcessData.hbm.xml file.I'm sure that there is currently not ProcessData.hbm.xml in my application.
And I got the track stack from SystemOut_11.06.29_10.44.54.log when Hibernate initialization.So where was ProcessData.hbm.xml from?
Code:
[6/29/11 10:43:53:094 CST] 00000080 Configuration I org.hibernate.cfg.Configuration addJar Found mapping document in jar: com/ibm/cdl/scst/domain/processdata/ProcessData.hbm.xml
[6/29/11 10:43:53:202 CST] 00000080 HbmBinder     I org.hibernate.cfg.HbmBinder bindRootPersistentClassCommonValues Mapping class: com.ibm.cdl.scst.domain.processdata.ProcessData -> PROCESSDATA


Dose anyone have the suggestions or solution for the issue?
Thanks for your help in advance!

Regards
