JBoss Twiddle을 사용한 애플리케이션 디플로이

JBoss AS5 이전 2009/01/22 14:38

주의할 점은 "file://" 이후에 redeploy 대상의 application 명이 와야 합니다.

1) deploy

/home/jchoi/jboss-4.2.3GA/bin>./twiddle.sh -s jnp://127.0.0.1:1099 -u admin -p admin invoke "jboss.system:service=MainDeployer" deploy "file:///home/jchoi/domains/testdomain/deploy/echo.war"

2) redeploy

/home/jchoi/jboss-4.2.3GA/bin>./twiddle.sh -s jnp://127.0.0.1:1099 -u admin -p admin invoke "jboss.system:service=MainDeployer" redeploy "file:///home/jchoi/domains/testdomain/deploy/echo.war"

3) undeploy

/home/jchoi/jboss-4.2.3GA/bin>./twiddle.sh -s jnp://127.0.0.1:1099 -u admin -p admin invoke "jboss.system:service=MainDeployer" undeploy "file:///home/jchoi/domains/testdomain/deploy/echo.war"

JBoss - Oracle T4 Connection 얻어오기

JBoss AS5 이전 2009/01/19 10:00

import java.sql.Connection;
import javax.naming.InitialContext;
import javax.sql.DataSource;

public class OracleConnectionUtil
{
 public static Connection getOracleConnection(String jndi)
  try{
   InitialContext ctx = new InitialContext();
   DataSource datasource = (DataSource) ctx.lookup(jndi);
   Connection connection = datasource.getConnection();
   //cast this to JBoss specific WrappedConnection
   org.jboss.resource.adapter.jdbc.WrappedConnection wrappedConnection =  (org.jboss.resource.adapter.jdbc.WrappedConnection) connection;
   //get the underlying connection (T4CConnection)
   Connection underlyingConnection = wrappedConnection.getUnderlyingConnection();

   //cast to T4CConnection if some specific API on this object is to be used
   oracle.jdbc.OracleConnection t4cConnection = (oracle.jdbc.OracleConnection) underlyingConnection;
   out.println("Oracle Connection : " + t4cConnection);
   return t4cConnection;
  }catch(Exception e) {
   System.out.println("Exception while getting oracle connection :::: " + e.getMessage());
  }
  return null;
 }

 public static void close(Connection conn) {
  try{
   if( conn != null ) conn.close();
  }catch(Exception e) {
   // Ignore when the connection closing
  }
 }
}

// 오라클에서 얻어온 connection을 close할 경우 casting된 connection은 실제 connection이므로
// close시 실제 연결이 끊어지게 되는 현상이 발생합니다.

// 아래의 같이 DataSource의 proxy connection을 close해야만 WAS의 connection pool로 반환하게 됩니다.  

   Connection conn = DataSource.getConnection();
   Connection oracleConn = conn.getUnderlyingConnection();
  
   //Do JDBC stuff heere

   //CLOSE THE HANDLE, NOT THE UNDERLYING CONNECTION!!!!
   conn.close();
 
   conn = DataSource.getConnection();
   oracleConn = conn.getUnderlyingConnection();

아래의 코드를 복사하셔서 web application context에 vm.jsp로 저장하신 후 확인하시면 됩니다.
