某人要检查以解决OC4J 10.1.3.5中的UnsupportedOperationException的第一件事是什么？这是在注销过程中发生的。我们有两个完全相同的应用程序（从编码和类路径的角度来看）-一个正确注销，另一个抛出UnsupportedOperationException。

最佳答案
如果不支持某些操作，则库抛出java.lang.UnsupportedOperationException。
这是完全可选的，应在API中进行记录。
例如，这在JDBC驱动程序中很常见，在该驱动程序中，即使对于同一数据库，一个驱动程序也可能抛出该驱动程序，而其他驱动程序则不会抛出该异常（Oracle驱动程序和weblogic内部驱动程序经常发生这种情况）
因此，您首先要查看的是库文档，然后看看有什么替代方法。

顺便说一句，您要做的第二件事是在metalink中创建一个服务请求（或现在称为的请求）
