Hi All,
Following is my mapping.xml file. I would like to use Oracle sequence for
inserting value into En_ID field.
<key-generator name="SEQUENCE" alias="seqgen">
<param name="sequence" value="{0}_SEQ"/>
</key-generator>
<class name="com.PCPgo.prm.web.encounter.EncounterJdo" identity="id">
<description>Encounter</description>
<map-to table="ENCOUNTER" xml="group" />
<field name="id" type="long" key-generator="seqgen">
<sql name="EN_ID" type="integer" />
<xml node="element" />
</field>
<field name="name" type="string" >
<sql name="EN_NAME" type="varchar" dirty="ignore"/>
<xml node="element"/>
</field>
</class>
Now, While creating EncounterJdo object, I am setting value as follows.
EncounterJdo encounterJdo= new EncounterJdo();
encounterJdo.setName("Allan");
if (db == null)
throw new InternalException("DB is null");
db.begin();
db.create(encounterJdo);
db.commit();
db.close();
but it inserts EN_ID =0 and NAME = "Allan" and now if I run again it throws
following error. It means it doesn't generate sequence
org.exolab.castor.jdo.DuplicateIdentityException: Duplicate identity found
for
object of type com.PCPgo.prm.web.encounter.EncounterJdo with identity 0:
an objec t with the same identity already exists in persistent storage
Hope for solution.
Best regards,
Kumar
