我的网络应用程序从JNDI获取数据源:
javax.naming.InitialContext ctx = new javax.naming.InitialContext();
javax.sql.DataSource ds = (javax.sql.DataSource)
ctx.lookup("java:comp/env/jdbc/db");
在应用的WEB-INF/web.xml
中,我有:
<resource-ref>
<description>DataSource</description>
<res-ref-name>jdbc/db</res-ref-name>
<res-type>javax.sql.DataSource</res-type>
<res-auth>Container</res-auth>
</resource-ref>
在应用的WEB-INF/ibm-web-bnd.xml
中,我有:
<web-bnd
xmlns="http://websphere.ibm.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://websphere.ibm.com/xml/ns/javaee http://websphere.ibm.com/xml/ns/javaee/ibm-web-bnd_1_0.xsd"
version="1.0">
<virtual-host name="default_host"/>
<resource-ref name="jdbc/db" binding-name="jdbc/db"/>
</web-bnd>
在WebSphere Liberty Profile的server.xml
中,我(保留相关部分):
<server description="new server">
<featureManager>
<feature>jsp-2.2</feature>
<feature>jdbc-4.0</feature>
</featureManager>
<library id="oracle-lib">
<fileset dir="lib" includes="ojdbc5_g.jar"/>
</library>
<dataSource jndiName="jdbc/db" jdbcDriverRef="oracle-driver" type="javax.sql.DataSource">
<jdbcDriver libraryRef="oracle-lib" id="oracle-driver"/>
<connectionManager numConnectionsPerThreadLocal="10" id="ConnectionManager" minPoolSize="1"/>
<properties user="user" password="password"
url="jdbc:oracle:thin:@//db-server:1521/db"/>
</dataSource>
</server>
当应用程序尝试从JNDI获取数据源时,它会失败,并显示以下错误:
CWNEN0030E: The @Resource factory encountered a problem getting
the object instance jdbc/oracle binding object. The exception message was:
failed to resolve jdbc/oracle to javax.sql.DataSource:
javax.naming.NameNotFoundException:
Intermediate context does not exist: jdbc/oracle
我在这里缺少什么?

我们在Liberty 8.5.5上使用DB2,我们在 server.xml
中使用<dataSource id="db2" isolationLevel="TRANSACTION_READ_COMMITTED" jndiName="jdbc/db2" type="javax.sql.DataSource">
<jdbcDriver>
<library>
<fileset dir="/usr/lib/java/ibm-db2-universal-driver" includes="db2jcc4.jar, db2jcc_license_cisuz.jar, db2jcc_license_cu.jar"/>
</library>
</jdbcDriver>
<properties.db2.jcc databaseName="DB2T" portNumber="21020" serverName="db2t.lvm.de"/>
<containerAuthData password="{xor}KzspMC04" user="tdvorg"/>
</dataSource>
也许有帮助。

在我的情况下,下面的解决方案适合我。
我在Eclipse中创建了一个名为“Resources”的“Generic project”。在这个项目中,我创建了一个文件function downloadFile () {
var data = new blob([$scope.document.base64Code], {type: $scope.document.mimeType+';base64'});
var config = {
data: data,
filename: $scope.documentSaveAs ? $scope.documentSaveAs : $scope.document.FileName
}
fileSaver.saveAs(config);
}
,内容如下:
dataSource.xml
我将这个文件拖放到Eclipse中进行服务器配置,或者在<server>
<dataSource id="ccm" jndiName="jdbc/ccm" type="javax.sql.DataSource">
<jdbcDriver id="oracle-driver" libraryRef="oracle-lib"/>
<connectionManager id="ConnectionManager" minPoolSize="1" numConnectionsPerThreadLocal="10"/>
<properties.oracle password="password" url="jdbc:oracle:thin:@128.1.30.150:1521:ccmdes" user="ccm"/>
</dataSource>
<library id="oracle-lib">
<fileset dir="C:\Oracle\product\10.1.0\Client_1\jdbc\lib" includes="ojdbc14_g.jar"/>
</library>
<jdbcDriver id="oracle" libraryRef="oracle-lib"/>
</server>
中创建一行:
server.xml
文件<include location="${shared.config.dir}/dataSource.xml"/>
是这样的:
server.xml
