我在使用 java 1.6 时没有收到此错误
这是我用于资源绑定(bind)的 web.xml 片段
<resource-ref id="xxx-data-source">
<description>XXX Datasource</description>
<res-ref-name>jdbc/xxxDatasource</res-ref-name>
<res-type>javax.sql.DataSource</res-type>
<res-auth>Container</res-auth>
<res-sharing-scope>Shareable</res-sharing-scope>
</resource-ref>
当我从我的数据源名称中删除 java:comp/env 前缀时，我能够绕过这个错误
例如:我正在使用
jdbc.jdr.datasource=jdbc/XxxDatasource
代替
jdbc.jdr.datasource=java:comp/env/jdbc/XxxDatasource
但我无法从所有地方(在某些 jar 中)删除它。
有没有人遇到过这个问题？
谢谢
最佳答案
即使答案来晚了，我也希望它能对某人有所帮助。
我也遇到了一个问题
javax.naming.ConfigurationException: NamingManager.getURLContext cannot find the factory for this scheme: java
在我的例子中，它出现是因为我在 web.xml 和 ibm-web-bnd.xmi 描述符中使用了 3.0 版。
当我改用 ibm-web-bnd.xml 描述符时，它起作用了。
所以对我来说你应该使用
我也写了一篇关于我遇到这个问题的博客
