HI all,

I am getting Constraint Violations while doing this.

1. I am retriving Master Object from DB
2. Removing Childs from the Master Object
3. Adding New child objects To master by using HashSet.
4. Updating the Master.

While Updating the Master I am getting the Constraint Violation Error in Child Object.

Here is the Coding

Master POJO
Code:
/**
* @hibernate.class table="JOB"
*
*/
public class Job extends BaseObject {
   private Integer version;
   private Long jobId;

   private String jobNo;
   private String jobType;
   private String jobSts;
   private String blNo;

   private Set jobDocSums=new HashSet();
   private Set jobDocs=new HashSet();



   /**
    * @return Returns the version.
    * @hibernate.version column="VERSION"
    */
   public Integer getVersion() {
      return version;
   }
   /**
    * @param version The version to set.
    */
   public void setVersion(Integer version) {
      this.version = version;
   }
   /**
    * @return Returns the blNo.
    * @hibernate.property
    * @hibernate.column name="BL_NO" length="60"
    */
   public String getBlNo() {
      return blNo;
   }

   /**
    * @return Returns the jobId.
    * @hibernate.id column="JOB_ID"
    * generator-class="increment" unsaved-value="null"
    */
   public Long getJobId() {
      return jobId;
   }
   /**
    * @return Returns the jobNo.
    * @hibernate.property
    * @hibernate.column name="JOB_NO" not-null="true" length="60" unique-key="JOB_UK"
    */
   public String getJobNo() {
      return jobNo;
   }
   /**
    * @return Returns the jobSts.
    * @hibernate.property
    * @hibernate.column name="JOB_STS" length="1"
    */
   public String getJobSts() {
      return jobSts;
   }
   /**
    * @return Returns the jobType.
    * @hibernate.property
    * @hibernate.column name="JOB_TYPE" length="60" not-null="true"
    */
   public String getJobType() {
      return jobType;
   }

   public Set getJobDocs() {
      return jobDocs;
   }
   /**

   public void setJobDocs(Set jobDocs) {
      this.jobDocs = jobDocs;
   }
   public void addJobDocs(JobDoc jobDoc)
   {
      jobDoc.setJob(this);
      jobDocs.add(jobDoc);
   }
   /**

     * @hibernate.collection-key column = "JOB_ID"
     * @hibernate.collection-one-to-many class ="model.JobDocSum"
    */
   public Set getJobDocSums() {
      return jobDocSums;
   }
   public void setJobDocSums(Set jobDocSums) {
      this.jobDocSums = jobDocSums;
   }
   public void addJobDocSum(JobDocSum jobDocSum)
   {
      jobDocSum.setJob(this);
      jobDocSums.add(jobDocSum);
   }

}

}


My ManagerImpl method
Code:
public class InterfaceManagerImpl extends BaseManager implements InterfaceManager
{
   private Log log = LogFactory.getLog(InterfaceManagerImpl.class);

   private JobManager jobManager;

   public void setJobManager(JobManager jobManager)
   {
      this.jobManager = jobManager;
   }


   public Long updateDocs(String excelFile, String sheetName,String userId) {

      Job jobObj = null;
      int count = 0;
      try
      {
         Workbook w = Workbook.getWorkbook(new File(excelFile));
         if (sheetName == null)
            sheetName = "Sheet1";
         if (sheetName.equals(""))
            sheetName = "Sheet1";
         Sheet s = w.getSheet(sheetName);

         Cell[] row = null;

         String blNo = "";
         String blpInCd = "";

         if(s != null)
         {
            log.info("NO OF ROWS :"+s.getRows());
            for (int i = 1; i < s.getRows(); i++)
            {
               row = s.getRow(i);

               blNo = getDo(row);

                  {
                     if (jobObj.getJobDocs() != null)jobObj.getJobDocs().removeAll(jobObj.getJobDocs());

                     JobDoc docObj = new JobDoc();
                     JobDocSum docSum = new JobDocSum();
                     if (!blpInCd.equals(""))

                         jobObj.addJobDocs(docObj);
                     }

                     jobManager.updateJob(jobObj);
                     count++;
                  }
               }
            }
         }
      } catch (Exception e)
      {
         e.printStackTrace();
         return new Long(0);
      }
      return new Long(count);
   }


}


This is My Service.xml file
