"Using hibernate Tools to generate Sql Script" To view the discussion, visit: https://community.jboss.org/message/797369#797369 -------------------------------------------------------------- We wanted to generate SQL Script (DDL) from POJO class which are Hibernate Annotated. I have tried using both hibernate3 maven plugin as well as with the Schema Exporter. Now this class also has a Sequecne Generator defined, and I was expecting that there would be a Sequence script generated for it as well. This is what the code looked like in the Entity with respect to the Sequence, the allocationSize here is defined as 50, I have tried using all different sizes. @Entity @SequenceGenerator(name="sessionInfoIdSeq", sequenceName="SESSIONINFO_ID_SEQ", allocationSize=50) public class SessionInfo { @Id @GeneratedValue(strategy = GenerationType.AUTO, generator="sessionInfoIdSeq") private Integer id; I am using following JARS: I am using the following jars : hibernate-tools - 3.2.4.GA, hibernate-core - 3.6.1.Final, hibernate-entitymanager - 3.6.1.Final, hibernate-validator - 4.1.0.Final, hibernate-validator-legacy - 4.0.2.GA and DB related jars. Now when I tried debugging the code using the SchemaExporter example I found that the class in hibernate-core jar was getting called for generating the sequence text. The problem is that it was only creating create sequence SESSIONINFO_ID_SEQ; At line 146 on SequenceGenerator.java it was using +String[] ddl =+ +dialect.getCreateSequenceStrings(sequenceName) from the Dialect class which happened to be deprecated.+ This method implementation was +public String[] getCreateSequenceString(String sequenceName) {+ ++ +return "create sequence " + sequenceName; //starts with 1, implicitly+ ++ +} + +The Dialect API said instead to usefollowing method. + protected String getCreateSequenceString(String sequenceName, int initialValue, int incrementSize) throws MappingException { if ( supportsPooledSequences() ) { return getCreateSequenceString( sequenceName ) + " start with " + initialValue + " increment by " + incrementSize; } throw new MappingException( "Dialect does not support pooled sequences" ); } I checked the latest APi of the hibernate-core and it too uses the deprecated method. Any inputs on this would be appreciated. Do I need to raise a JIRA? I have attached a sample example that I used to generate the Code, SchemaExporter.7z.
