java - Hibernate not save Entity to oracle db -


I have created a small crude app using hibernate with struts2, spring, oracle db Adding Mathos to Action Class 
  public string ads () throws exceptions {t.setAO_CreatedBy ("me"); T.setAO_Name ("OK"); Orgdao.addOrg (t); // emplist = empdao.showEmployuee (); Return success; }   
 Entity class for the exam:  
  @Entity @Table (name = "test") Public class test {@Id @Column (name = "AuUID") @Sewense Generator (name = "sequence organizer", sequence name = "SEQ_AT_ORGANISATION", allocation size = 1) @ Generated Values ​​(strategy = generation type, sequence, generator = "sequence generation maker") Private int AO_ID; @column (name = "AO_name") private string AO_Name; @colom (name = "AO_CreatedBy") private string AO_CreatedBy; Public int getAO_ID () {return AO_ID; } Public Zero set AO_ID (int aO_ID) {AO_ID = aO_ID; } Public string getAO_Name () {return AO_Name; } Public Zero Set AO_Name (string aO_Name) {AO_Name = aO_Name; } Public string getAO_CreatedBy () {AO_CreatedBy; } Public Zero Set AO_CreatedBy (string aO_CreatedBy) {AO_CreatedBy = aO_CreatedBy; }}   
 DAO method:  
  Public Zero addOrg (Test T) {//System.out.println""save: "+ org); Session session = null; Session = sessionfactory.open session (); {System.out.println ("Try save before:" + t.getAO_ID ()); Session.save (t); System.out.println ("after saving:" + t.getAO_ID ()); } Hold (exception e) {e.printStackTrace (); }   
 I did not get any errors and the data has not been DB. I tested this code with mysql and it works fine, i think this problem is way out of the way with this sort of sequence.  
  Before saving: 0   
 Hibernate:  
  SEQ_AT_ORGANIZATION.nextval select from double  < / pre> 
 After saving: 1   
 
 
 Can you try  
  Public Zero addOrg (Test T) {//System.out.println""save: "+ org); Session session = sessionfactory.open session (); Transaction tx; Try {Tx = session.beginTransaction (); session.save (t); tx.commit (); System.out.println ("after saving:" + t.getAO_ID ()); } Hold (exception e) {if (tx! = Null) tx.rollback (); E.printStackTrace (); } Finally {session.close (); }

Java - Error: no suitable method found for add(int, java.lang.String) -

I'm in the middle of homework work and I'm stuck. At this point in my code, I think that I should have a GUI window that opens and allows me to type "inserted text number". Notice is not going anywhere but at this point, If I pass through the problem then it will be in a linked list. I am getting two of the same error for the lines. Add (index, element); And I can not seem to get past it, there is no suitable method for the error "add (int, java. string string)". Code is below, please advise. To clarify - this will not be a method error because it is a linked list. There should not be any way involved. import java.awt. *; Import java.awt.event. *; Import javax.swing. *; Import java.util. *; Import java.util.Scanner; Import java.util.LinkedList; Public class TopTenList JFrame {Private TopTenList tt; See the Private JTextArea list; Private JTextField cmdTextField; Private JTextField resultsTestfield; // This GUI window is the code for the public toptist...

java - JPA TypedQuery: Parameter value element did not match expected type -

I am using JPA 2.0 and getting the following code in the DAO layer: Public Zero Test () {string key = "status"; String [] Conditions = {"A", "B"}; & Lt; TestTable & gt; Results = Search (Keys, Conditions); } Public listing & lt; TestTable & gt; Search (string key, object value error) {string sql = "test ndf to testlet and jade nand." + Key + "in:" + key; TypedQuery & LT; TestTable & gt; Query = entityManager.createQuery (SQL, TestTable.class); Query.setParameter (key, Arrays.asList (valueArr)) / *** Error Line *** Return query.getResultList (); } In the above error line, it throws the following exception: java.lang.IllegalArgumentException: parameter value element [[Ljava.lang.String; @ cbe5bc] did not match the expected type [java.lang.String] Why is this expected type string while actually this string []?

c++ - static template member variable has internal linkage but is not defined -

Yes, I know, there is a question with almost the same title, but it refers to a different situation. Error message) In my case, I have a .cpp file with a big named designation name (implementation details). There is a property class template with a static data member in that name space, which I need to access from outside the unknown namespace. I give it a little bit of meat: file.hpp namespace Bar {template & lt; Typename A & gt; Struct foo {static_assert (is_same & lt; a, float & gt; :: value} is_same & lt; a, double>: value, ""); Fixed zero set_static_var (a const & x); // ...}; } and file.cpp namespace {template & lt; Typename A & gt; Struct foo_traits {// supports the implementation of several static code bars: foo & lt; & Gt; Fixed A data; }; The template's & lt; & Gt; Float foo_traits & lt; Float & gt; :: datum; // No change if this is in the global namespace template & lt; & Gt; Doub...
