JForum安装

1、准备环境：TOMCAT6.0、JDK1.5、jforum2.1.7、mysql.5.0

2、下载jforum，可以到http://www.trydone.com/posts/list/196.page上下载。下载后讲war文件部署在tomcat/webapps下

3、启动mysql服务mysqld-nt.exe。可能会出现启动错误，把c:\windows\my.ini删除即可

4、在mysql中建数据库jforum：create database jforum character set utf8，执行jforum\WEB-INF\config\database\mysql下的mysql_db_struct.sql建表，在mysql命令行下执行:source mysql_db_struct.sql。这里推荐一个mysql的工具：Mysql Control Center，该工具可以创建数据库表

5、启动tomcat，运行http://localhost:8080/jforum/install.jsp进行安装，注意两项设置，默认显示语言选择Chinese Simplifed (zh_CN)数据库编码选择utf-8，对其他项设置，点击下一步：核对设置，点击开始安装：安装成功，点击进入论坛。

6、安装完毕。但是出现了问题如下，应该是连接数据库的问题：

Expression templateName is undefined on line 5, column 14 in exception.html. The problematic instruction: ---------- ==> ${templateName} [on line 5, column 12 in exception.html] in include "${templateName}/message.htm" [on line 5, column 1 in exception.html] ---------- Java backtrace for programmers: ---------- freemarker.core.InvalidReferenceException: Expression templateName is undefined on line 5, column 14 in exception.html. at freemarker.core.TemplateObject.assertNonNull(TemplateObject.java:124) at freemarker.core.Expression.getStringValue(Expression.java:11 at freemarker.core.Expression.getStringValue(Expression.java:93) at freemarker.core.DollarVariable.accept(DollarVariable.java:76) at freemarker.core.Environment.visit(Environment.java:196) at freemarker.core.MixedContent.accept(MixedContent.java:92) at freemarker.core.Environment.visit(Environment.java:196) at freemarker.core.Environment.renderElementToString(Environment.java:1461) at freemarker.core.StringLiteral.getStringValue(StringLiteral.java:95) at freemarker.core.Include.accept(Include.java:110) at freemarker.core.Environment.visit(Environment.java:196) at freemarker.core.MixedContent.accept(MixedContent.java:92) at freemarker.core.Environment.visit(Environment.java:196) at freemarker.core.Environment.process(Environment.java:176) at freemarker.template.Template.process(Template.java:232) at net.jforum.exceptions.ExceptionWriter.handleExceptionData(ExceptionWriter.java:110) at net.jforum.JForum.handleException(JForum.java:284) at net.jforum.JForum.service(JForum.java:205) at javax.servlet.http.HttpServlet.service(HttpServlet.java:803) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:290) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206) at net.jforum.util.legacy.clickstream.ClickstreamFilter.doFilter(ClickstreamFilter.java:59) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:235) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:22 at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:175) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:12 at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:105) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:109) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:212) at org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:81 at org.apache.coyote.http11.Http11Protocol$Http11ConnectionHandler.process(Http11Protocol.java:624) at org.apache.tomcat.util.net.JIoEndpoint$Worker.run(JIoEndpoint.java:445) at java.lang.Thread.run(Unknown Source)

7、这个问题是由于创建数据库时没有指定为utf-8引起的，现已解决。
