Corba传值包含中文解决

分布式系统中，如果两个系统使用corba进行传值，一般来说服务器没有进行相应的特殊配置，传非中文是没有问题的，如果传输的参数中包含中文，那么就会报如下错误：

com.sun.corba.se.impl.encoding.CodeSetConversion$JavaCTBConverter convertCharArray
警告: "IOP02400001: (DATA_CONVERSION) Character does not map to negotiated transmission code set"
org.omg.CORBA.DATA_CONVERSION: vmcid: OMG minor code: 1 completed: No

后来在网上搜了搜，看见一个哥们说需要这么做：

java.util.Properties p = new java.util.Properties();
p.setProperty("com.sun.CORBA.codeset.charsets", "0x05010001, 0x00010109"); // UTF-8, UTF-16
p.setProperty("com.sun.CORBA.codeset.wcharsets", "0x00010109, 0x05010001"); // UTF-16, UTF-8
orb = org.omg.CORBA_2_3.ORB.init(args, p);

其实上面主要就是说进行转码的操作，以及设置服务器上面支持的语言，但是我愣是看的不是很爽，答案不明了呀！其实解决方法很简单，只要仔细看下错误，异常的堆栈中会告诉你你操作那个一个属性的时候出现了异常，也就表示这个属性在corba的传输过程中存在着中文，对其进行相应的转码即可。异常堆栈的提示信息如下：

根据idl生成的文件查看属性是否包含中文，对该字段进行转码即可，^_^。
