程序在本机运行没有问题，迁移到aix系统上面，查询数据库的时候就会报下面这个问题，我这是在osgi平台上面运行的程序，程序错误如下

问题终于解决了，在这里对帮助我的朋友说声谢谢，既然解决了就说说解决的办法吧，我在ibm官网偶然发现，在osgi平台上面操作db2的的驱动用db2jcc4.jar，db2jcc_license_cisuz.jar，（我原来用的是db2jcc.jar,db2jcc_license_cu.jar）,把jar包更换之后，在aix上面启动平台依然会报找不到sun.io.ByteToCharConverter，但是程序倒是可以正常运行，数据库操作都正常，到现在还是弄不明白具体原因，但是总算程序能正常运行，启动报异常只能后续再慢慢研究了，最后还是要对大家说声谢谢！
