Problem in BeerAdvice

[Micheal John]

Hi,

I'm preparing for SCWCD in K&B's HF book.
I am just trying the sample beer application. While I'm starting the tomcat, I am getting the following error message and the application is not deploying. I am using Tomcat 4.1.. and JDK 1.5..
Error Message while starting the tomcat server:

Download tomcat5
Download Tomcat5
Then deploy application again.

[Niranjan Deshpande]

Download tomcat5
Download Tomcat5
Then deploy application again.

thats not a very wise advice !

hey...john...you can try this -

change the declaration at the yop of the d.d as -

version = "2.4"

the server trace tells that your xml is invalid. th exsd being used is 2.4, but the version is 2.3

hth !

[Micheal John]

I have problem in downloading tomcat 5.0.... due to some restructions :roll:

Is the problem to due to Tomcat version 4.1.... ?

[Micheal John]

Thanks Niranjan Deshpande !!

After chaning the version 2.3 to 2.4, it's deploying and my application is working..but still the below error/warning/?? message is coming.. can you tell me why this is coming? It's telling some parser exceptions..
