java - __pm 和 __nontx 后缀是什么？

Question

当我尝试在 glassfish 服务器上运行该应用程序时，我的 Java EE 应用程序出现以下错误。它说 “无效资源:jdbc/busservice__nontx”。我应该去哪里解决这个错误？以前它给出了“jdbc/busservice__pm”的错误。一旦我创建了 JDBC 资源并连接到连接池，错误就消失了。但是我仍然遇到“jdbc/busservice__nontx”错误

Answer 1

不要将“jdbc/busservice__pm”添加到您的 Glassfish JDBC 资源中，只需将其添加为“jdbc/busservice”。看起来 __pm 和 __nontx 是一些内部名称，它在内部添加到您的 jdbc 名称的末尾，当您专门添加它时，它会把它弄乱并抛出该错误。
