Hello,

I am calling one create() method in my entity bean. I have correct values for all fields (one int for the primary key and the rest are integer also). When I try to run it I get a strange error which I will paste in at the bottom (duplicate column name).

17:05:44,030 ERROR [OsdProofsWeekReplace] Could not create entity
java.sql.SQLException: ORA-00957: duplicate column name

a:1371)
????????at oracle.jdbc.driver.OracleStatement.doExecuteWithTimeout(OracleStateme
nt.java:1900)
???.......... and so on.....

When I have been removed relationships with another entity beans in my cantainer, create() method works correctly -- insert new string into my table. I have many such entity beans and I got one thing -- I may call create() method succesfully when current bean HAS NOT relationships FROM another beans...

I have not a relationship where the foreign keys are part of the primary keys in my case. I have simple integer primary and integer foreign key only.
When I have been turned on debug, I got next error message in jboss application server console:

2002-08-06 09:58:39,167 DEBUG [org.jboss.ejb.plugins.cmp.jdbc.JDBCCreateEntityCommand.PmInfoVacations] Create: pk=61

java.sql.SQLException: ORA-00957: duplicate column name
????????at oracle.jdbc.dbaccess.DBError.throwSqlException(DBError.java:168)

Insert statement here is incorrect -- INFO_VACATION_ID is primary key in this table (Integer), first CLOCK_NUMBER - foreign key from another table, LEAVE_KIND_ID - foreign key to another table (it is unimportant in this case) and other fields -- just data. But what is second CLOCK_NUMBER field in this INSERT statement? First CLOCK_NUMBER - real field in the table, but second... Does anybody has any idea?
Is there any way to solve my problem?

If anyone can help it would be greatly appreciated.
