我们的应用程序使用Tomcat8(确切地说是Tomcat8.0.30)和Java8。使用ojdbc7数据库驱动程序以及所有其他jar,例如ucp.jar和ons.jar等,使用Oracle数据库11g。如果我启用'verbose:class'在我的java应用程序中,即在Tomcat中,它显示了从ojdbc.jar和ucp.jar文件加载的所有类。
现在我们已经将数据库升级到12c,因此我们将数据库驱动程序升级到12.2ojdbc8.jar。我替换了所有JAR(ojdbc、ucp、ons),但Tomcat抱怨并给出错误NoClassDef发现了异常。当我用同样冗长的verbose:class'选项,我看不到从ojdbc8.jar加载任何类(来自ucp.jar的类不会被加载)。jar文件就在$CATALINA\u HOME/lib位置。但不知道为什么ojdbc8.jar没有被加载。
感谢您对解决此问题的任何帮助。
