[CTJUG Forum] Re: JDO - getObjectById()

[Leon van der Merwe]

For those who want to know….   Code in application:   Product dbProduct = null; try { Object object = pm.getObjectId(product);             dbProduct = (Product) pm.getObjectById(new Product.ID(product.getPOSFILE_DET_GTIN())); } catch (Throwable t) { t.printStackTrace(); }   Must add inner class in jdo object public static class ID implements java.io.Serializable {         public String POSFILE_DET_GTIN;           public ID() {           }                 public ID(String s) {             POSFILE_DET_GTIN = s;         }           public boolean equals(Object o) {             if (this == o) {                 return true;             }               if (!(o instanceof Product.ID)) {                 return false;             }               final Product.ID id = (Product.ID) o;             if (this.POSFILE_DET_GTIN != id.POSFILE_DET_GTIN) {                 return false;             }               if (this.POSFILE_DET_GTIN != id.POSFILE_DET_GTIN) {                 return false;             }             return true;         }   Then specify inner class inside jdo metadata file: <class               name="Product"               table="Product"               requires-extent="true"               identity-type="application"               objectid-class="Product$ID">     And it works!!!         -----Original Message----- From: CTJUG-Forum@googlegroups.com [mailto:[EMAIL PROTECTED] On Behalf Of Leon van der Merwe Sent: Tuesday, February 07, 2006 12:16 PM To: CTJUG-Forum@googlegroups.com Subject: [CTJUG Forum] JDO - getObjectById()   I am trying to determine if I must do an insert or update by trying to get the object from the db by using the primary key.   Something like this:   Product dbProduct = (Product)pm.getObjectById(primaryKey); If (dbProduct != null) {             //update } else {             //insert }   I keep getting:  javax.jdo.JDOObjectNotFoundException: No such object FailedObject:2050000001574   The object is there but its throwing its toys?
