嘗試查找數據庫時獲取javax.naming.NameNotFoundException

Question

我從Eclipse開發了一個REST Web服務，其目的是調用我們試圖在我們正在使用的JBoss服務器中的standalone-full.xml文件中配置的數據庫。 問題是，看起來我們已經錯誤地配置了數據庫或錯過了某種類型的步驟，因此我不確定我缺少哪一步來解決問題。

Web服務調用此方法並在getconnection調用中失敗：

public List<Object> getObjects(long id){

    List<Objects> objects = new ArrayList<Objects>();

    final StringBuffer query = //query removed here;
    this.logger.info("Get Action: " + query.toString());
    Statement ps = null;
    Connection con = null;
    ResultSet rs = null;        

    try {
        con = this.getConnection("DBNAME2");
        ps = con.createStatement();
        SourceMaterial material = null;
        rs = ps.executeQuery(query.toString());
        while(rs.next()) {
            //fields and object logic here
        }
    } catch (SQLException ex) {
        this.logger.error(ex.getMessage());
    } finally {
        this.cleanUp(rs, ps, con);
    }

    return objects;
}

最終命中此代碼並在jndiName查找上拋出異常：

protected void init(String dataSource) throws NamingException {

    String jndiName = "";

    if(dataSource.equals("DBNAME"))     
        jndiName = "java:jboss/datasources/jbpmDS"; 
    else if(dataSource.equals("DBNAME2"))   
        jndiName = "java:jboss/datasources/ondisplayDS";    

    Hashtable<String, String> parms = new Hashtable<String, String>();
    parms.put(Context.INITIAL_CONTEXT_FACTORY, "org.jboss.as.naming.InitialContextFactory");
    //parms.put(Context.URL_PKG_PREFIXES, urlPkgPrefixes);
    InitialContext ctx = new InitialContext(parms); 
    this.datasource = (DataSource) ctx.lookup (jndiName);
}

JNDI名稱在我們的standalone.xml文件中配置，如下所示：

<datasource jndi-name="java:jboss/datasources/ondisplayDS" pool-name="ondisplayDS" enabled="true" use-java-context="true">
                <connection-url>jdbc:sqlserver://ServerNameHere:1931;databaseName=DataBaseNameHere;SendStringParametersAsUnicode=true;SelectMethod=cursor;user=GEN_DW_R;password=Re-KcU814RNWau</connection-url>
                <driver>sql</driver>
                <pool>
                    <min-pool-size>5</min-pool-size>
                    <max-pool-size>20</max-pool-size>
                </pool>
            </datasource>

這會拋出這個堆棧跟蹤：

我再次假設有一個簡單的解決方法。 我唯一的問題是我實際上並不知道從JBoss配置數據庫的正確程序，我真的只是在猜測。

有沒有人有任何見解或可以指出我在缺少配置步驟的程序的方向？

Answer 1

我最終進入了我的服務器的管理控制台，並添加了我在獨立文件中配置的數據源，現在代碼正常工作。
