Hi Kristian, For me this does not look like a OJB bug, but as a configuration problem. If you have a java attribute of type String but have defined it as INTEGER in the repository.xml you've got a problem!
If you want to have a String attribute converted into an Oracle Number column you should use a FieldConversion but not change the PlatformOracleImpl. cheers, thomas > -----Original Message----- > From: kristian meier [mailto:[EMAIL PROTECTED] > Sent: Thursday, June 05, 2003 9:46 AM > To: OJB Users List > Subject: Re: Possible OJB Bug with Oracle > > > Hello, > > when I yesterday switch to oracle I came across the same > exception and I > investigated a bit, and > found an unexpected situation in the PlatformOracleImpl.java > > in the setObjectForStatement( .... ) method the sqlType was > Type.INTEGER > and the value was a String class > both arguments were passed to the PlatformDefaultImpl.java where they > were passed into the PreparedStatement. > > the String class seemed to be already wrong at this place, > but a simple > hack does work fine for me: > > *** PlatformOracleImpl.java Sun May 4 14:08:14 2003 > --- > src/java/org/apache/ojb/broker/platforms/PlatformOracleImpl.java > Thu Jun 5 09:17:58 2003 > *************** > *** 126,131 **** > --- 126,138 ---- > ps.setLong(index, ((Integer) value).intValue()); > } > + else if (sqlType == Types.INTEGER && value > instanceof String) > + { > + // workaround: > + ps.setInt(index, Integer.parseInt( (String) value ) ); > + } > else > { > + this.logger.debug( "using type " + sqlType + " for > class " + > value.getClass().getName() > + + "(" + value + ")" ); > super.setObjectForStatement(ps, index, value, sqlType); > } > > maybe this also helps to find the real bug !!! > > with best wishes Kristian > > > > Brown, Melonie S. - Contractor wrote: > > >Has anybody else ran into this?
