我想知道是否有人可以幫助我使用tomcat（最有可能的）配置問題。當通過apache tomcat運行時，無法運行h2數據庫查詢8
我正在使用tomcat 8/eclipse Mars/h2數據庫。建立一個項目（寫入h2的示例獨立應用程序）並且工作正常（我可以看到行被添加到數據庫中）。但是，當我嘗試在我的Web應用程序中使用相同的步驟時 - 我收到一個異常。
之前在這裏張貼的問題，我看這些鏈接：。 http://j2stuff.blogspot.com/2012/11/setup-datasource-for-h2-and-postgres-on.html Configuring Liberty Profile to use H2 database https://keithrieck.wordpress.com/2010/01/28/h2-database-on-tomcat/ （以及更多:-(），但仍無法使我的申請工作
這裏是調用堆棧

下面是從context.xml中的部分（在eclipse - >服務器）
<ResourceLink name="jdbc/h2"
auth="Container"
type="javax.sql.DataSource"/>
下面是從server.xml中的部分（在Eclipse - >服務器）
<Resource name="h2" auth="Container"
global = "h2"

這裏是我的persistence.xml

這裏是單獨工作在支架上的代碼應用程序，我試圖從Web應用程序調用
public class DBTalkImplementation {
EntityManagerFactory emf = Persistence.createEntityManagerFactory("h2");
public DBTalkImplementation()
{
System.out.println("In default constructor");
//Class.forName("org.h2.Driver");
}
//Function to add row to the database (person table)
public void AddPerson(int AssociateID, String First, String Last)
{
System.out.println("inAddPerson");
EntityManager em = emf.createEntityManager();
EntityTransaction tx = em.getTransaction();
tx.begin();
System.out.println("DBTalkImplementation.CreatePerson");
Person _person = new Person(AssociateID,First,Last);
System.out.println(_person.toString());
em.persist(_person);
tx.commit();
em.close();
}
最後 - 這是我的web應用程序中的函數n即失敗
@Override
public void addPerson(Person person) {
System.out.println("addPerson "+person.getFirstName());
DBTalkImplementation DB = new DBTalkImplementation();
DB.AddPerson(person.getId(), person.getFirstName(), person.getLastName());
dataStore.put(Integer.valueOf(person.getId()), person);
}
任何有關該問題的幫助或至少對後續步驟的建議非常感謝。
