在服务器上的RESTful web服务上运行时出现自由服务器错误

Question

当我开始在eclipse中运行服务器时，我是IBM websphere mq的新手。它总是出现以下错误，如找不到mdb-3.2或wmqjmsclient-2.0的要素定义

Launching defaultServer (WebSphere Application Server 8.5.5.9/wlp-1.0.12.cl50920160227-1523) on Java HotSpot(TM) 64-Bit Server VM, version 1.8.0_77-b03 (en_US)

我已经在server.xml中定义了它们

<featureManager>
        <feature>jsp-2.3</feature>
        <feature>jdbc-4.0</feature>
        <feature>localConnector-1.0</feature>

Answer 1

JDBC 4.0是Java EE 6的一个特性，Liberty 8.5.5.9默认安装了Java EE 7特性(我想您会发现JDBC 4.1已经在您下载的包中了)。如果您需要使用JDBC4.0，您可以将其与4.1一起安装到Liberty中，并选择在server.xml中使用哪个版本。有关如何安装其他特性的信息，请查看wasdev.net，JDBC4.0的页面是here

Answer 2

我会试着总结这些帖子和评论。

因此，如果您下载了WLP Java EE7或JavaEE7Web Profile，则只能获得JavaEE7规范所需的特性。jdbc-4.0来自Java EE 6，jdbc-4.1来自Java EE 7。因此，您需要切换到jdbc-4.1 (推荐)或安装jdbc-4.0特性。

要列出可用的功能，请发出以下命令：

C:\IBM\WebSphere\wlp\bin>productInfo.bat featureInfo

您可以使用installUtility命令逐个安装附加功能，也可以安装捆绑包。

为了拥有JavaEE6、JavaEE7和WebSphere中特定的所有特性，例如MQ客户端，发出以下命令：

C:\IBM\WebSphere\wlp\bin>installUtility install baseBundle

您可以在Liberty features in the bundles中查看捆绑包中包含的所有功能
