我有一个在 Websphere 应用服务器上运行的 Java 应用程序。当我分析系统崩溃核心转储文件时，我得到如下信息：

ERROR: Symbol file could not be found.  Defaulted to export symbols for J9THR23.dll

如何获取 Java 的符号文件？

提前致谢。

您可以在此站点上获得 JDK 的调试版本。

http://download.java.net/jdk6/

查找 jdk-6u12-ea-bin-b03-windows-i586-debug-22 dec 2008.jar，91.47 MB

它包括 .pdb 文件

看起来调试器正在寻找 PDB 文件，据我所知，Java 应用程序的调试信息不​​是 PDB 文件。PDB 文件是由 VisualStudio 在创建 Windows 本机应用程序时生成的，因此调试器似乎正在寻找应用程序服务器的调试符号。不知道 WebSphere 是否带有自己的调试版本。另一方面，如果您想要调试 Java 应用程序的符号，您只需要使用该-g选项重新编译它。
