Versions
Eclipselink 2.1
Oracle 10.2.0.4
Tomcat 5.5.26
Using JPA, I am attempting to persist a java.util.Calendar object to an Oracle Timestamp With Time Zone column. From what I have read, Eclipselink is supposed to just handle this for Oracle DB.
However, an attempt at a direct mapping:
@Entity
@Table(name="TIMESTAMP_TZ_TEST")
public class TimestampTzTest {
@Id
private Long id;
@Column(name="TIME")
private Calendar time;
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public Calendar getTime() {
return time;
}
public void setTime(Calendar time) {
this.time = time;
}
}
fails during startup because
The attribute [time] from the entity class [class eg.model.TimestampTzTest] does not specify a temporal type.
Next, I try using a TypeConverter
@Column(name="TIME")
@Convert("timestamptz")
@TypeConverter(name="timestamptz", dataType=TIMESTAMPTZ.class)
private Calendar time;
This results in an error during execution:
Caused by: java.lang.ClassCastException: org.apache.tomcat.dbcp.dbcp.DelegatingCallableStatement cannot be cast to oracle.jdbc.OracleCallableStatement
at oracle.sql.TRANSDUMP.getTransitions(TRANSDUMP.java:42)
at oracle.sql.TIMEZONETAB.updateTable(TIMEZONETAB.java:456)
at oracle.sql.TIMESTAMPTZ.toTimestamp(TIMESTAMPTZ.java:571)

at org.eclipse.persistence.platform.database.oracle.Oracle9Platform.getTIMESTAMPTZFromResultSet(Oracle9Platform.java:192)
From what I have found during search, this appears to be caused by the Tomcat connection pool not returning the underlying OracleCallableStatement.
I have not been able to find a solution to this problem. Can someone please guide me?
