我试图将证书导入Linux Centos服务器,但似乎该keytool命令无法正常工作,我遇到以下错误:

-bash: ./keytool: No such file or directory

知道如何keytool在linux上启用命令吗？

我正在使用tomcat 7 + ZK框架+ axis2开发一个Web门户来使用Web服务.过了一会儿我开始收到这个错误:

也许axis2 1.6与tomcat 7不兼容？

我有一个查询，我必须多次使用它的结果。因此，我不想多次运行查询，而是想将查询值保存到变量中一次并多次使用它以加快查询速度。

例如：

声明 VAr = 从 TBT 选择 M_DATE

如果我运行以下查询查询:

SELECT day.M_CMP_TYPO AS M_CMP_TYPO,
        day.M_SPTCV as M_SPTCV,
       day.M_CNT_VS2 AS M_CNT_VS2,
       day.M_CNT_ORG AS M_CNT_ORG,
       day.M_PL_CGR2 AS M_PL_CGR2,
       day.M_PL_CGU2 AS M_PL_CGU2,
       day.M_PL_CSFI2 AS M_PL_CSFI2,
       day.M_PL_FTFI2 AS M_PL_FTFI2,
       day.M_PL_RVR2 AS M_PL_RVR2,
       day.M_PL_RVU2 AS M_PL_RVU2,
       day.M_TRN_FMLY AS M_TRN_FMLY,
       day.M_TRN_GRP AS M_TRN_GRP,
