在WebSphere上下文之外訪問LTPA令牌

Question

我有一個在tomcat中部署的web應用程序，並且從這個web應用程序中，我必須使用部署在Websphere中的SOAP服務。要訪問此服務，我需要傳遞LTPA令牌。我對websphere很陌生，不知道如何在我的web應用中獲得LTPA令牌？我無法修改在web球體中部署的應用程序的實現。

我可以通過使用HttpBasicAuthentication達到此目的。這裏是代碼片段 -

public class TokenHelper { 

private static Logger logger = LoggerFactory.getLogger(TokenHelper.class); 

private static final int HTTP_TIMEOUT_MILISEC = 100000; 
private static String lineSeparator = System.getProperty("line.separator"); 

@Value("#{'${hostname}'}") 
private String hostName; 

@Value("#{'${port}'}") 
private int port; 

@Value("#{'${contextpath}'}") 
private String contextPath; 

@Value("#{'${isbasicauthentication}'}") 
private boolean isBasicAuthentication; 

@Value("#{'${username}'}") 
private String basicAuthenticationUserName; 

@Value("#{'${userpassword}'}") 
private String basicAuthenticationPassword; 

public Map<String, String> getLtpaToken() throws Exception {  
    Cookie[] cookies = null; 
    Protocol protocol = null; 
    Map<String, String> cookiesMap = new HashMap<String, String>(); 

    GetMethod method = new GetMethod(); 
    HttpClient client = new HttpClient(); 
    method.getParams().setSoTimeout(HTTP_TIMEOUT_MILISEC); 
    protocol = new Protocol("http", new DefaultProtocolSocketFactory(), getPort()); 

    if (isBasicAuthentication) { 
     client.getParams().setAuthenticationPreemptive(true); 
     Credentials defaultcreds = new UsernamePasswordCredentials(getBasicAuthenticationUserName(), getBasicAuthenticationPassword()); 
     client.getState().setCredentials(new AuthScope(getHostName(), getPort(), AuthScope.ANY_REALM), defaultcreds); 
    } 
    // Execute request 
    try { 
     client.getHostConfiguration().setHost(getHostName(), getPort(), protocol); 
     method = new GetMethod(getContextPath()); 
     method.setFollowRedirects(true); 

     logger.info(methodName, "URL to get:" + getContextPath()); 
     // Execute the GET method   
     int statusCode = client.executeMethod(method); 
     if (statusCode != -1) { 
      cookies = client.getState().getCookies(); 

      StringBuffer sb = new StringBuffer(); 
      for (int j = 0; j < cookies.length; j++) { 
       cookiesMap.put(cookies[j].getName(), cookies[j].getValue()); 
       sb.append("CookieName=" + cookies[j].getName() + lineSeparator); 
       sb.append("Value=" + cookies[j].getValue() + lineSeparator); 
       sb.append("Domain=" + cookies[j].getDomain() + lineSeparator); 
      } 
      sb.append("Status Text>>>" + HttpStatus.getStatusText(statusCode)); 
      logger.debug("Cookies are: {}" + sb.toString()); 

      method.releaseConnection(); 

     } 
    } catch (Exception e) { 
     logger.error("Error while getting LTPA token using HttpBasicAuthentication for URL {}" +e); 
     throw new RuntimeException("Error while getting LTPA token using HttpBasicAuthentication for URL:" + contextPath, e); 
    } finally { 
     // Release current connection to the connection pool once you 
     // are done 
     method.releaseConnection(); 
    } 
    return cookiesMap; 
}
