关于javaMail发邮件途中网络中断应该怎么处理,求高手解决!

wglg520 2010-10-26 04:21:06
如题,求高手指点,小弟想尽办法捕获各种异常还是会报com.microsoft.sqlserver.jdbc.SQLServerException: Connection reset by peer: socket write error和连接到主机tcp/ip已中断异常,我想做到如果发邮件途中网线被拔掉了给个友好页面提示一下,而不是页面一堆报错信息!

捕获到这个异常就知道是终端了，在catch中再做提示处理

按道理异常都捕获了就不会抛向页面的
不是很明白··

代码放在tryCatch里,后台跟踪进了catch,页面有自定义的错误提示信息,return不管到本页面还是另外的页面,页面都会有一堆java的报错信息!

在catch块中可以进行代码处理。可以在里面return一个指定的值 或者是 在方法里面建集合当有异常时往集合中添加错误信息。

然后把错误信息传到页面中 比如说STRUTS的国际化 EL表达式

C++课程设计题目源代码
打开链接下载源码： https://pan.quark.cn/s/589796089f72 C++课程设计任务列表，涵盖以下内容：1、识别并显示10至99范围内，各位数乘积超过各位数和的数值，例如数字12不满足条件，因为1乘以2小于1加2，故不输出；而数字27满足条件，因为2乘以7大于2加7，因此需要输出该数。2、开发一个功能，用于从用户输入的任意数量实数中找出最大值与最小值：首先要求用户输入一个正整数n，代表数值的个数，随后用户可输入任意n个实数，程序需找出这n个数中的最大值和最小值并将它们展示出来。3、实现两个已排序数组的合并操作：设有数组A和B，且假设这两个数组的元素均已按照降序排列。编写程序将A和B合并成一个新的数组C，并确保C中的元素同样保持降序排列。int A[10]={123, 86,80, 49,33,15,7,0,-1,-3}；int B[10]={100,64,51,50,27,19,15,12,5,2}；4、设计一个函数，用于计算特定分数序列前n项的总和，该序列为1/2,1/3,1/4,1/5,1/6,1/7,...。要求在主程序中提示用户输入一个整数n，并验证输入的合法性（n需大于1方为有效），若输入合法，则调用求和函数并显示计算结果。5、编写一个程序，计算两个用户输入日期之间的天数差：用户需以year1，month1，day1和year2，month2，day2的格式输入两个日期，程序随后计算这两个日期之间的天数间隔，并将结果输出到屏幕上。要求编制具有如下原型的函数difs2Date：long GetDayDifference（int y1,int m1,int d1,int y2,int m2,int d2）；并在主函数中调用此函数，将计...
SAP ABAP调试器高级技术
代码下载地址： https://pan.quark.cn/s/ee8627e4e6d7 ABAP调试器是一种功能强大的工具，可用于在执行期间对ABAP代码进行检验。除了常规的核心功能（例如逐行运行代码以及检验变量、字段符号和引用的值）之外，它还提供了一些辅助性的特性，能够简化并压缩调试会话的时长。并非所有使用者都熟悉这些辅助特性。SAP ABAP调试器是处理和优化ABAP代码开发与维护工作的核心资源，它配备了多样的功能来协助开发人员在运行状态下进行检验和排除故障。此资源着重阐述了ABAP调试器的一些高级特性，涵盖了深入分析调用堆栈、系统级调试、更新会话调试以及提升调试效率的方法。 1. **深入分析调用堆栈**：除了常规的应用程序调试，开发人员有时需要对调用堆栈的内部层级进行深入调试，特别是在错误出现在异步执行的更新处理或系统级程序时。通过启用**系统级调试**，可以访问通常不公开的系统代码，但这也会导致调用堆栈的显著增加，因此需要审慎操作。 2. **系统级调试**：对于不含业务逻辑的系统级程序，开发人员通常无需进行调试。然而，在特定情形下，例如进行错误追踪时，可能需要进入系统代码。借助调试器的“系统调试启用/禁用”选项，可以赋予对系统程序的调试权限。 3. **更新会话调试**：在处理异步更新任务，例如持久化业务数据时，错误可能发生在更新任务内部。激活**更新会话调试**，在更新任务完成后，调试器将自动启动，展示执行路径。比如，在变更成本中心后，通过输入调试指令 "/h" 启动调试，保存后能够看到更新过程中的错误。 4. **分析调用堆栈**：在进行深入调试时，调用堆栈是至关重要的。通过分析调用堆栈，能够定位到引发问题的具体位置，如在VB_V2_NORMAL...
