public class DocDetailsEntity {
#Id
#GeneratedValue(generator="seqGen",strategy=GenerationType.SEQUENCE)
private Integer docId;
private String docName;
private String docDesc;
private String userId;
#Lob

(
docId number(10) primary key,
docName varchar2(50) not null,
docDesc varchar2(100),
userId varchar2(10) not null,

Answer 1

Could you please try to write as
#Table(name="docUpload",schema = "schemaName" )
#SequenceGenerator(name="seqGen",sequenceName="schemaName.seqName")
