/ * ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- ------------------------ Write in front: I see many netizens's questions are related to server configuration, build a reliable and safe application development The server is the foundation of web programming, especially for friends who have developed JSP on Linux.
This document is the crystallization of my multi-year server configuration. I haven't been modified by my N before publishing (the last big revision is just released in RH7.2, and then because I have not found a mistake because I didn't find any mistakes, I didn't have it. Upgrade), the document is reprinted by the antenna network at the end of 2001 (http://www.yesky.com/20020206/217592.shtml), then reproduced by LinuxBYE.NET, CNJSP.com and other Linux and Java communities, after the time test I have never been discovered by you so far.
Documentation is not ideal in the web page, if you want to get PDF of this document, or have any comments, you can mail to Roczhao@msn.com
The document is longer, divided into more articles, this is the ninth article, the following is the text: -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- ----------------------------------------- * /

RESIN 2.0.5 (Built THU NOV 15
17:56:24 PST
2001)
reasons may be:
1. The JDK version you installed is too low that the JDBC version is not 2.0;
2, greater possibility is that your driver does not support JDBC2.0, JDBC just provides an abstract class interface, which requires drivers to be implemented as its physical class.
Solution:
1. Upgrade JDK, my suggestion is IS J2SDK-1_3_1_01-linux-i386.bin, see the JVM Install section;
2, replace the database driver, you are likely to use mysql_comp.jar, use mm.mysql-2.0.4-bin.jar.zip to replace it. Common error six: Chinese garbled
possible reason:
When installing the operating system, you don't have the i18n's simplified package and do not handle it in the source file.
Solution:
1, html method, add the following line to your JSP source code:
2, JSP mode one:
<% @ Page ContentType = "text / html; charset = GB2312"%>
3, JSP mode 2:
Generally speaking, using RESIN does not require this method, I have never used it. Only by using Dong Dong, which is like Tomcat, it is possible to use this cumbersome method, but this method has its advantages, that is Improve the portability of the program, not for the system or the engine garbled.
<%
String chs = "This method is definitely!";
BYTE [] BCHS = chs.getbytes ();
OUT.PRINT (New String (BCHS, "8859_1");
