从WAS迁移到自由时，JNDI上下文初始化错误 [英] JNDI Context Initialization error while migration from WAS to liberty

问题描述

未找到 WsnInitialContextFactory 类.Liberty不支持此类，那么如何删除 jndi.properties 默认设置.此属性文件包含 InitialContext 的此类名称.

The WsnInitialContextFactory class not found exception. Liberty does not support this class, then how can I remove jndi.properties default settings. This property file contain this class name for InitialContext.

属性:

INITIAL_CONTEXT_FACTORY = "com.ibm.websphere.naming.WsnInitialContextFactory" 
CC_PROVIDER_URL = "iiop://localhost.svr.us.xxxxxxx.net:41516"

InitialContext 查找:

   try {
        Hashtable params = new Hashtable();
        params.put(Context.INITIAL_CONTEXT_FACTORY, ADProperties.WS_INITIAL_CONTEXT_FACTORY);
        params.put(Context.PROVIDER_URL, ADProperties.AD_PROVIDER_URL);

        Context ctx = new InitialContext(params);
        try {
            ds = (DataSource) ctx.lookup("java:comp/env/" + jndiName);
        } catch (Exception ex) {
            LogUtil.debugException("DBConnectionManager", "Exception in init: Resource reference DataSource lookup Error.", "init()", ex, "");
            try {
                ds = (DataSource) ctx.lookup("jdbc/" + jndiName);
            } catch (Exception exp) {
                LogUtil.debugException("DBConnectionManager", "Exception in init: Datasource lookup Error.", "init()", exp, "");
            }
        }

例外:

推荐答案

自由不支持WsnInitialContextFactory类.您可以做到这一点(它也可以在传统的WebSphere中工作):

Liberty does not support the WsnInitialContextFactory class. You can just do this (and it'll work in WebSphere traditional as well):

try {
    Context ctx = new InitialContext(new Hashtable());
    try {
        ds = (DataSource) ctx.lookup("java:comp/env/" + jndiName);
    } catch (Exception ex) {
        LogUtil.debugException("DBConnectionManager", "Exception in init: Resource reference DataSource lookup Error.", "init()", ex, "");
        try {
            ds = (DataSource) ctx.lookup("jdbc/" + jndiName);
        } catch (Exception exp) {
            LogUtil.debugException("DBConnectionManager", "Exception in init: Datasource lookup Error.", "init()", exp, "");
        }
    }
