JPA: em.find() returns no result although there is one

Question

Hi all,
my JEE application is running on weblogic 10.3, I use eclipseLink 1.1.3 for persisting objects and transactions/entity manager are container managed. In some cases when I try to get an object the find() method of EntityManager returns null although there is an entry in the database. The time elapsed between insert and query is more than a minute (hopefully a commit is done within that period of time). So how could this happen?
Kind regards,
Michael

Hello,
Are you using list or library? If it is library then try with below query:
SPQuery dQuery = new SPQuery();
dQuery.ViewAttributes = "Scope=\"RecursiveAll\"";
dQuery.Query = "<Where>" +
"<Eq>" +
"<FieldRef Name=\"FileLeafRef\"/>" +
"<Value Type=\"Text\">" + fileName + "</Value>" +
"</Eq>" +
"</Where>";

You can also download CAML builder to build query (see my reply in below thread where you will get download link)
