之后，得到的回复是，tomcat5.5是为java5开发的，不能在j2se1.4.x下运行，除非是安
装一个package。不过tomcat5.5的文档中没有相关的信息，我当时并不知道。现在用5.0.

Tomcat 4.0 on Linux, trying to connect to MySQL
It can't find the data source I defined and throws this error:
javax.servlet.ServletException: Cannot create resource instance
I'm not sure if there's any security setting preventig this?
I can access MySQL using the following jsp code:
Class.forName("org.gjt.mm.mysql.Driver");
Connection dbcon = DriverManager.getConnection(loginUrl,
loginUser, loginPasswd);
Statement statement = dbcon.createSta |

发帖数: 10 | 3 If you defined the JNDI name for the datasource on Tomcat platform, you don't
even need to declare a corresponding resource-ref in your web.xml file. Your
jndi lookup code should be able to locate the datasource directly. |

发帖数: 16 | 4 Does tomcat implement EJB container? Or Jboss has to be installed to use EJB?
Can Jboss alone handle the webapps? |

JBoss is.
There is another free OpenEJB, I haven't tried it yet.

发现：
1. tomcat/conf/web.xml中有svg mime type的重复定义，我删除了重复；
2. ff 1.5有内置的svg支持，我删除了adobe svg viewer plug-in for ff。
新的试验结果：
ie6 with adobe svg viewer:
- can display svg files from other websites
- can display svg files from localhost
- cannot display svg files from other sites in xhtml (localhost)
- cannot display svg files from localhost in xhtml (localhost)
ff 1.5 with native svg support:
- can properly display svg files from other websites
- cannot display svg files from localh |

发帖数: 2497 | 15 不应该是路径的问题吧。
我用sysdeo启动tomcat是没有问题， 只是用tomcat5w.exe启动， 就不行。

发帖数: 2416 | 16 Looks like a OS path issue, too. I have a theory - just a theory - sysdeo
starts tomcat from within eclipse, so it inherits whatever envirionment
eclipse provides. On the other hand, tomcat5w.exe sets up a different
environment (e.g. without passing along all the OS environment variables). |

发帖数: 25 | 17 Now I am deploying a web application on Solaris9. In the application, I have
to use a JVM Profiler.
I developped it on WindowsXP with Eclipse and Sysdeo plug-in. It is easy to
add -Xrun* JVM argument when starting Tomcat server on Windows with IDE. But
in Solaris, I have no idea how to add -Xrun to startup.sh file.
Any body know how to add -Xrun* JVM argument to startup.sh file?

发帖数: 25 | 18 Now I am trying to launch an external application in my web application, and
killing it by PID after a while. But when I execute Runtime.getRuntime.exec
() in my JSP page or Servlet, Tomcat is stuck in that page and do not
display anything. It seems that it will run forever. Is there any solution
to solve this problem?
BTW, I do not use System.exit() in my program. It may cause Security Manager
problem.
Thanks! |

发帖数: 62 | 19 I am a little surprised to see that even tomcat tries to implement server
push.
is it a trend to do it today? Comments? |

发帖数: 62 | 20 1. As I know server push has nothing to do with browsers. In most
implementations, either javascript or ajax is used.
2. HTTP protocol inversion is a mechanism for ajax push. If interested, you
can google it to find more explanation
The major issue for server push is scalability (of course there are some
other concerns). Even with java nio, things do not look promising.
As i said I am surprised to see there are many implementations now, even
tomcat tries it. I thought it might take a little lo |

发帖数: 2166 | 30 o. Not about the fixing of the compilation.
We have group of site designers they only develops JSP pages but
knows little about java.
What they complain is that when they wrote JSP, they could not have any clue
where is the JSP is wrong, they want to see the error message on their
browser.
they have no clue about what is printed to the tomcat console... |
|

发帖数: 367 | 31 Tomcat only print the JSP error. In order to print your own stack, you need
to catch that exception, store the message in the session.
When rendering the JSP page, check if message is null, if not, print it. |

发帖数: 34805 | 32 That probably depends on your app server.
I use tomcat exclusively and jsp compilation error

发帖数: 2416 | 34
I think in tomcat everything that blows up blows
all the way up to the browser window, and you'd
have to specifically configure it _not_ to do so.
I would start with the web.xml from your own app's
and see if there are any error pages declared. |

发帖数: 493 | 43 Check your deployment file structure. You should have some directory called
webapps/myapps in the tomcat root. And as myapps's direct child, you should
have index.jsp file. If you index.jsp is in myapps/WEB-INF, you will see the
error like this since you cannot access it from outside.
(actuallY once you fully understand how to deploy web app, you will know
that a url pattern can be forced to map any servlet/jsp inside WEB-INF) but
for a beginner I think that might be your problem. |
