Except JDBC, are there any other solutions for Java-based technologies(such
as JSP, Servlets, etc) to connect to Databases including IBM DB2 and Oracle?
The major operations on the database will be information retrival, browsing,
or searching. I guess it's mainly web-based too. It's for an University Library project and not enterprise so
couldn't afford expensive solutions.
I can only think of JDBC. When I searched google, I found something named JDO

in JSP, Servlet, u still use JDBC to connect with database layer
JDO? sounds like ADO's Java version? interesting :) |

发帖数: 126 | 6 Not necessarily Tomcat's problem. You should test your JDBC driver program. It
should be in your CLASSPATH. One thing you can do is to write a standalone
program to do a database query. If this works, then copy the db access code to
your JSP.

发帖数: 2 | 14 I don't know the Chinese version.
One solution is to use IBM websphere application server
to plug in a web server. That's a commercial solution.
You can use IBM visual age for java to develop servlet
and debug jsp.
You can get a trial version of websphere application server
and visual age for java from IBM web page.

PHP是一种没有前途的嵌入式脚本语言。原因是多方面的。
一，PHP缺乏规模支持。与之类似的嵌入语言，一个是ASP，一个是JS
P前者可以通过
Microsoft Windowsd的COM/DCOM获得ActiveX支持，后者可以通过SUN
Java的Java
Class和EJB获得支持
二，缺乏多层结构支持。对于大负荷站点，解决方法只有一个：分布
计算。数据库、应
用逻辑层、表示逻辑层彼此分开，而且同层也可以根据流量分开，组
成二维阵列。ASP
可以通过DCOM和微软的Transcation Server来获得
这种结构支持，JSP可以通过EJB/CORBA以及众多厂商的Application
Server来获得这种
结构支持，但PHP没有这样的条件。
三，PHP极其没有道理地实现了一个混乱的不能统一的数据库接口支
持，比如对Oracle,
MySQL， Sybase的接口，彼此都不一样。这一点让人感觉不可思议，
而且也使它在电子
商务中运用受阻----连PERL都通过DBI而获得一个抽象的数据库接口
！

发帖数: 31 | 17 expression language, so that you can write scripts like ${foo.bar}.
those are supposed not java, but 'simpler' language for page authors.
SimpleTag or 'tag file'. the taglib can be implemented in JSP syntax,
not have to be in a java class. this is a lot easier.
SimpleTag is decoupled from servlet context, so that it 'COULD' be
used as template page independently in 'FUTURE'. I want this badly,
but still it's not available. |

Saw the short version demo, it's cool. However, nothing really new (jsp,

more.
If it's free, it might be the best plug-in for eclipse. However, it's not.

发帖数: 559 | 31 我这个学期刚刚写了个类似网上住址登记处的PROJECT，用了JSP，SERVLET，WEBSERVICE
，JAAS和JMQ，EJB，MY SQL和XML DB。东西不少，但是基本是东拉西扯四处抄了些代码和
SAMPLE，最终可以运行了，错误还不少，什么SESSION，安全问题等等。之前基本不会编J
SP，粗通JAVA，能撺在一起跑起来已经是很不错了。
这个学期还要一个比较进阶的类似项目，我想好好从头学一下如何规规矩矩写一个类似网

发帖数: 274 | 33 if it is under unix/linux, you can set a link (using ln) to text.txt
from doc root of your web application.
If it is under windows, set a shortcut, but I am not sure if this
works.
another solution, you create a jsp, which reads text.txt and displays
it. |

发帖数: 445 | 34 It's browser interpret "/" as your application root. not jsp in this case.
the browser always get other files relative to this page or relative to the
tag if it exists. If browser find the url init with "/" it will always
go to web application root to find the path.
now you should know how to set. |

You still need to import the package in the jsp. Read the documentation

发帖数: 126 | 39 JSP files can be at anywhere under your document root. Supporting class files

发帖数: 559 | 40 据我阅读，大概以下几种
SERVLET里面：
session.get/setAttribut("XXX",XXX)
request.set/getAttribut("XXX",XXX)
PageContext.get/setAttribut("XXX",XXX,SLOPE)
JSP里面可以直接用上面几个常量，或者set bean
请问前两种和最后一种有什么不同么？哪些利弊，一般用哪个
我转递一个自定义的BEAN，很奇怪的是只有session正常，其他都不对，好像程序死在那
里，也不出错，好怪。我觉得是最通常的应用呀，一般出问题会是什么地方呢
另外按一般经验，购物网站一般用REQUEST还是SESSION来保存比较合适。 |

发帖数: 137 | 44 It's fairly standard, and covered by almost all JSP/Servlet books. Or you can
google it. Basically you uses a "file" element in the html form, and when user
submit the form, your servlet will open the inputstream of the httprequest and
read the data (handling the multi-part msg). |
