I have actually figured this problem out, but it took me days, so I thought I would paste my solution here to aide others.

我实际上已经解决了这个问题，但我花了几天时间，所以我想我会在这里粘贴我的解决方案来帮助其他人。

I am using Fedora 11, and in Eclipse I tried adding a Tomcat 6 server and starting it. I would get the following error:

我使用的是 Fedora 11，在 Eclipse 中我尝试添加一个 Tomcat 6 服务器并启动它。我会收到以下错误：

'Starting Tomcat v6.0 Server at localhost' has encountered a problem.

Server Tomcat v6.0 Server at localhost failed to start.

'Starting Tomcat v6.0 Server at localhost' 遇到问题。

Server Tomcat v6.0 Server at localhost 启动失败。

Then in my console I got the following:

然后在我的控制台中，我得到以下信息：

Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/juli/logging/LogFactory
  at org.apache.catalina.startup.Bootstrap.<clinit>(Bootstrap.java:54)

Could not find the main class: org.apache.catalina.startup.Bootstrap. Program will exit.

I'll post the solution in an answer below.

1. In Eclipse, Open the "Server" tab.
2. Double click on the "Tomcat6" entry to see the configuration.
3. Then click on the "Open launch configuration" link in the "General information" block.
4. In the dialog, select the "Classpath" tab.
5. Click the "Add external jar" button.
6. Select the file "/usr/share/tomcat6/bin/tomcat-juli.jar"
7. Close the dialog.
8. Start tomcat 6 from Eclipse.

1. 在 Eclipse 中，打开“服务器”选项卡。
2. 双击“Tomcat6”条目以查看配置。
3. 然后单击“常规信息”块中的“打开启动配置”链接。
4. 在对话框中，选择“类路径”选项卡。
5. 单击“添加外部 jar”按钮。
6. 选择文件“/usr/share/tomcat6/bin/tomcat-juli.jar”
7. 关闭对话框。
8. 从 Eclipse 启动 tomcat 6。

Hopefully posting it here will help some poor soul.

希望张贴在这里能帮助一些可怜的人。

I copied the contents of the "C:\Program Files\Apache Software Foundation\Tomcat 6.0\conf" directory to the "workspace\Servers\Tomcat v6.0 Server at localhost-config" directory for Eclipse. I refreshed the "Servers\Tomcat v6.0 Server at localhost-config" folder in the Eclipse Project Explorer and then everything was good.

我将“C:\Program Files\Apache Software Foundation\Tomcat 6.0\conf”目录的内容复制到 Eclipse 的“workspace\Servers\Tomcat v6.0 Server at localhost-config”目录。我刷新了 Eclipse 项目资源管理器中的“Servers\Tomcat v6.0 Server at localhost-config”文件夹，然后一切正常。

1. install tomcat

   # yum install tomcat6*

2. edit tomcat conf file

   # vim /etc/tomcat6/tomcat-users.xml

1. 安装tomcat

   # yum 安装 tomcat6*

2. 编辑tomcat conf文件

   # vim /etc/tomcat6/tomcat-users.xml

something like:

就像是：

<?xml version='1.0' encoding='utf-8'?>
<tomcat-users>
  <role rolename="tomcat"/>
  <role rolename="role1"/>
  <role rolename="manager"/>
  <role rolename="admin"/>
  <user username="tomcat" password="tomcat" roles="tomcat"/>
  <user username="both" password="tomcat" roles="tomcat,role1"/>
  <user username="role1" password="tomcat" roles="role1"/>
  <user username="TomcatAdmin" password="tomcat" roles="admin,manager"/>
</tomcat-users>

1. create root directory for your J2EE project, example:

   $ mkdir -p ~/Project/java/

2. do symbolic link, /usr/share/tomcat6/webapps/ to ~/Project/java/

   # ln -s /home//Project/java//dist/.war /usr/share/tomcat6/webapps/.war

1. 为您的 J2EE 项目创建根目录，例如：

   $ mkdir -p ~/Project/java/

2. 做符号链接，/usr/share/tomcat6/webapps/ 到 ~/Project/java/

   # ln -s /home//Project/java//dist/.war /usr/share/tomcat6/webapps/.war

Note: war archive file is created automatcaly when you use netbeans

注意：使用 netbeans 时会自动创建 war 存档文件

0r you can do:

0r 你可以这样做：

# ln -s /home/<login>/Project/java/<myProject>/webapps /usr/share/tomcat6/webapps/<myProject>

1. check /etc/hosts file, this file must contain the machine name, mine hosts file

   jonathan 127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6

2. start httpd service

   # service httpd start

3. check loclahost web page

4. start tomcat6

   # service tomcat6 start

5. check localhost:8080 web page

6. check that tomcat show your project
   if not:

   • check symbolic link and restart tomcat6 service
   • or add manualy with tomcat manager web page
     a) Set project name
     b) Se path to web.xml file
     c) Valid
     d) start your project (from web page)

1. 检查/etc/hosts文件，这个文件必须包含机器名，我的hosts文件

   乔纳森 127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6

2. 启动httpd服务

   # 服务 httpd 启动

3. 检查 loclahost 网页

4. 启动tomcat6

   # 服务 tomcat6 启动

5. 检查本地主机：8080 网页

6. 
   如果没有，请检查 tomcat 是否显示您的项目：

   • 检查符号链接并重启 tomcat6 服务
   • 或使用 tomcat manager 网页手动添加
     a) 设置项目名称
     b ) 设置web.xml 文件的路径
     c) 有效
     d) 启动您的项目（从网页）

for fedora 13 and under they are some problem, how fix it:

对于 Fedora 13 及以下版本，它们存在一些问题，如何解决：

# chmod -R g+w /var/log/tomcat6 /etc/tomcat6/Catalina  
# chmod -R g+w /usr/share/tomcat6/work/  

check in log files located in /var/log/tomcat6/ if they are anymore "permission denied" message

检查位于 /var/log/tomcat6/ 中的日志文件，如果它们不再是“权限被拒绝”消息

aforementioned solutions did not help me, I could solve it by re-installing the Tomcat server which took few seconds.

上述解决方案对我没有帮助，我可以通过重新安装花了几秒钟的 Tomcat 服务器来解决它。

在我的 PC 上，我必须在上述第 7 步之后再次打开 Tomcat6 条目，然后将默认选项更改Server locations为Use tomcat installation.
