Rakesh,

I just got into struts and have experienced the exact same problem. I just wonder if you've found the answer for this issue?

Thanks,
Mike

1. Do you have the struts.jar file in your /WEB-INF/lib directory?

2. What's in your deployment descriptor web.xml?

I have experienced the exact same problem too..
I have the struts.jar in my app_dir/WEB-INF/lib and this is my web.xml

Hi,

Remove &quot;;&quot; at the end of <!DOCTYPE .....> tag from the above web.xml and try.

Cheers,
Venu

 

[catire]

Oh.. sorry it was a mistake when I copied.... !!! In the web.xml this &quot;;&quot; it doesn't exist... !!!

Thanks
Alejamdro....

Hi,

Could you paste the ---Root Cause-- Excepiton that the tomcat is throwing. That would be helpful.


Cheers,

Hi,

I think you dont not have all the necessary .jar files in your class path. From the Exceptions above I think you are missing commons-digester.jar file.

The List of Jar files that are required in your Classpath for struts.

commons-beanutils.jar
commons-collections.jar
commons-digester.jar
commons-lang.jar
commons-logging.jar
commons-validator.jar (if using DynaActionForm)
struts.jar

Cheers,
Venu

Hi Venu...
Thanks for all of you advice... I tried what you said and it doesn't work.... I put the folder (C:\jakarta-struts-1.1\lib) where all of those .jar are in my WINDOWS classpath and I still can't compile the app.... If you have any other advice...

Thanks...
Alejandro

 

[venur]

Hi,

Try doing this, copy all those jar file into your Webapp lib folder and then compile.

Cheers,
Venu

 

[catire]

Yeeeesssss !!!! It works perfectly...!!! The Jbuilder compile the app and run perfect, now I have an error when I run the app, I don't know if it is my app or other problem with Jbuilder,Struts and JBoss because I make the .jar and .war and I put it into a web server and the app run perfect..... I'm going to check the source code, but if you get any advice this is the message that Jbuilder is throwing me when I submit the form:
