如何解决“无法解除绑定工厂从JNDI：org.hibernate.engine.jndi.JndiException？

Question

我有一个Java EE应用程序运行在Wildfly 10服务器上，我看到这个错误后，我完成了数量作为最大池大小（换句话说，如果我有5集的最大池大小，我得到六号尝试这个错误）中提到的请求

这里是我的数据源配置：

<datasource jta="true" jndi-name="java:/jdbc/ITS" pool-name="ITS" use-ccm="true"> 
        <connection-url>jdbc:oracle:thin:@prodrac-s..(conn URL here)/connection-url> 
        <driver>oracle</driver> 
        <pool> 
         <min-pool-size>2</min-pool-size> 
         <max-pool-size>5</max-pool-size> 
         <prefill>true</prefill> 
        </pool> 
        <security> 
         <security-domain>encrypted-password-its</security-domain> 
        </security> 
        <validation> 
         <valid-connection-checker class-name="org.jboss.jca.adapters.jdbc.extensions.oracle.OracleValidConnectionChecker"/> 
         <stale-connection-checker class-name="org.jboss.jca.adapters.jdbc.extensions.oracle.OracleStaleConnectionChecker"/> 
         <exception-sorter class-name="org.jboss.jca.adapters.jdbc.extensions.oracle.OracleExceptionSorter"/> 
        </validation> 
        <timeout> 
         <set-tx-query-timeout>false</set-tx-query-timeout> 
         <blocking-timeout-millis>0</blocking-timeout-millis> 
         <idle-timeout-minutes>30</idle-timeout-minutes> 
         <query-timeout>0</query-timeout> 
         <use-try-lock>0</use-try-lock> 
         <allocation-retry>0</allocation-retry> 
         <allocation-retry-wait-millis>0</allocation-retry-wait-millis> 
        </timeout> 
        <statement> 
         <share-prepared-statements>false</share-prepared-statements> 
        </statement> 
       </datasource> 

在我的数据源对于Oracle数据库我试图连接到最大池大小设置为5和最小池大小为2.我试图增加数量甚至20，但我得到的错误在21日尝试。

以下是完整的堆栈跟踪：

我想明确地关闭，像这样的连接：

} catch (NamingException ne) { 
      System.out.println(ne.getMessage()); 

     } catch (SQLException ne) { 
      System.out.println(ne.getMessage()); 

     } catch (Exception e) { 
      System.out.println(e.getMessage()); 
     } 
     finally{ 
      try { 
       HibernateSession.closeITSSession(); 

      } catch (Exception ex) { 
       log.error("Exception trying to close the Hibernate ITS session: "+ ex); 
       System.out.println(ex.getMessage()); 
      } 
     } 

能有人帮吗？

错误是由于部署目录中存在多个同名的WAR。
