This happened to me for the tomcat6 package on Mint 15. The installation had /usr/share/tomcat6/lib/commons-pool.jar -> ../../java/commons-pool.jarbut /usr/share/java/commons-pool.jar -> commons-pool-1.5.6.jarwas broken. Copying it from my local Maven repo sudo cp ~/.m2/repository/commons-pool/commons-pool/1.5.6/commons-pool-1.5.6.jar /usr/share/javafixed it for me.
对于 Mint 15 上的 tomcat6 包，这发生在我身上。安装已经/usr/share/tomcat6/lib/commons-pool.jar -> ../../java/commons-pool.jar但/usr/share/java/commons-pool.jar -> commons-pool-1.5.6.jar被破坏了。从我的本地 Maven 仓库复制它为我sudo cp ~/.m2/repository/commons-pool/commons-pool/1.5.6/commons-pool-1.5.6.jar /usr/share/java修复了它。

It seems the 'commons-pool' jar is not being deployed. If you are using eclipse, you can check which jars are deployed by going to the project's properties, and clicking Deployment Assembly.
似乎没有部署 'commons-pool' jar。如果您使用的是 eclipse，则可以通过转到项目的属性并单击部署程序集来检查部署了哪些 jar。

可能是你commons-pool-x.x.x.jar的 lib 文件夹中没有你的部署文件夹，这可以通过在apache-tomcat-7.0.54\lib文件夹中复制这个 jar 文件来解决
