Я пытаюсь создать веб-сервис в веб-приложении на NetBeans 8.2 (server-tomcat 8.0.27.0), который может подключаться к базе данных на Postgres и читать таблицу с именем «test». у меня есть этот код в download.java (веб-сервис в пакете под названием serve)
Download.java
@WebService(serviceName = "download")
public class Download {
Connection con=null;
private DataSource getJdbcPostgres() throws NamingException, SQLException {
Context c = new InitialContext();
DataSource ds=(DataSource) c.lookup("java:comp/env/jdbc/postgres");
con=ds.getConnection();
return ds;
}
@WebMethod(operationName = "download")
public String download(@WebParam(name = "username")String username, @WebParam(name = "id")String id) throws ClassNotFoundException, SQLException {
String sql = "select * from test where id="+id;
Class.forName("org.postgresql.Driver");
PreparedStatement pst=con.prepareStatement(sql);
ResultSet rs=pst.executeQuery();
ResultSetMetaData rsmd=rs.getMetaData();
rs.next();
return "";
}
}
вот мой файл context.xml (в META-INF)
context.xml
<?xml version="1.0" encoding="UTF-8"?>
<Context path="/service2">
<Resource name="jdbc/postgres" auth="Container"
type="javax.sql.DataSource" driverClassName="org.postgresql.Driver"
url="jdbc:postgresql://localhost:5432/postgres"
username="someusername" password="somepassword" maxTotal="20" maxIdle="10"
maxWaitMillis="-1"/>
</Context>
и вот web.xml (в WEB-INF):
web.xml

когда я пытался изменить сервер на GlassFish 4.1.1, он говорит:

Я новичок в этой области, поэтому, пожалуйста, помогите мне, если я где-то не прав или что-то упустил!
