通過Java來調用WTC服務

 在上面說過如何在Weblogic中如何配置WTC服務，下面給出具體的Java代碼的實現

package test;

import java.rmi.RemoteException;

import javax.naming.Context;
import javax.naming.InitialContext;
import javax.naming.NamingException;

import weblogic.wtc.gwt.TuxedoConnection;
import weblogic.wtc.gwt.TuxedoConnectionFactory;
import weblogic.wtc.jatmi.Reply;
import weblogic.wtc.jatmi.TPException;
import weblogic.wtc.jatmi.TPReplyException;
import weblogic.wtc.jatmi.TypedString;

public class WTCCaller {
 /**
  * 函數功能：執行調用命令，返回結果
  *
  * @param serviceName
  *            服務名，可能取值如下：在WTC中配置的服務，即Import中的配置

  * @param command 發送的命令
  *             * @return 返回的結果值（即tuxedo返回的值）

  * @throws TPException
  * @throws TPReplyException
  */
 public String execute(String serviceName, String command)
   throws TPException, TPReplyException, RemoteException {
   Context ctx;
  TuxedoConnectionFactory tcf;
  TuxedoConnection myTux;
  TypedString myData;
  Reply myRtn = null;

  try {
   ctx = new InitialContext();
   tcf = (TuxedoConnectionFactory) ctx
     .lookup("tuxedo.services.TuxedoConnection");
   } catch (NamingException ne) {
   String errorStr = "不能串連tuxedo服務,具體錯誤：" + ne;
   throw new TPException(TPException.TPENOENT, errorStr);
  }
  myTux = tcf.getTuxedoConnection();
  myData = new TypedString(command);

  try {
   myRtn = myTux.tpcall(serviceName, myData, 0);
  } catch (TPReplyException tre) {
   System.out.println("error occur");
   throw tre;
  } catch (TPException te) {
   System.out.println("error occur");
   te.printStackTrace();
   throw te;
  } catch (Exception ee) {
   String errorStr = "調用tuxedo服務出錯,具體錯誤：" + ee;
   throw new TPException(TPException.TPESYSTEM, errorStr);
  }

  if (myRtn != null) {
   myData = (TypedString) myRtn.getReplyBuffer();
   myTux.tpterm();
  }
        //System.out.print(myData.toString());
  return ("value:"+myData.toString());
 }

}
