Thanks Lachlan and Daniele!
Now I have learned the lesson about JDBC and plugIn ...
But I need again some help.
With the right JDBC+plugIn I have my sample web service running on
PostgreSQL: but still remain the strange search behavoir from the
strating point:
If I create an operation with a like or caseIsensitiveLike operator
the web service returns nothing (without error) while searching a part
of a string or returns the right record from DB while searching the
exact string (seem that work like a = operator) !!!
Moreover I have many data non traslated from java class that represent
the DB data:
({
(this=EOKeyGlobalID[Patient (java.lang.Integer)2]),
(patSex = <com.webobjects.foundation.NSKeyValueCoding$Null>),
(patient = <com.webobjects.foundation.NSKeyValueCoding$Null>),
(gpspss = {
)
}),
(updatedTime = 2007-03-22 08:34:16 Etc/GMT),
(gpppss = {
)
}),
(patBirthdate = 1985-03-14 23:00:00 Etc/GMT),
(mppss = {
)
}),
(patName = TOURNEVIX^^^^),
(studys = {
)
}),
(patIName = <com.webobjects.foundation.NSKeyValueCoding$Null>),
(patients = {
)
}),
(createdTime = 2007-03-22 08:33:37 Etc/GMT),
(patIdIssuer = <com.webobjects.foundation.NSKeyValueCoding$Null>),
(patPName = <com.webobjects.foundation.NSKeyValueCoding$Null>),
(mwlItems = {
)
}),
(patId = fDCztT),
(patAttrs = <com.webobjects.foundation.NSKeyValueCoding$Null>
})
What I miss?
Where's the next lesson I must learn?
Luigi
P.S. I have installed and run mySQL, recreate the same DB from PG to
mySQL but after modeling the DB and create the web service I have the
same behaviour: this should mean that the problem is not PostgreSQL
but some my bad DB modelling ...
