validate in ActionForm not working for errors
hi all, I have a simple form that takes username and passwd. for that i have a LogonForm bean, which has a validate method. if i enter both username and passwd it works fine and gets forwarded to the next page. but if there is an error in validate() and ActionErrors object is returned then my control goes to a blank page. I know that my ActionErrors object has been populated as i have checked it with debug statements. 'input' property in my action mapping is to index.jsp, that is the page itself. why is it showing me a blank page. why is the framework not showing any exception if there is one. any suggestions regards saurabh - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: java application to struts
Erik, then my question is what do i need to change in .xml file if i dont want anything to be returned back to the application from struts?. reading and writing to the stream is handled manually in servlets. Will it be like if i dont apecify in .xml file then nothing will be returned to the application. regards saurabh On Tue, 2004-08-17 at 10:26, Erik Weber wrote: > To your HTTP client, there should be no difference between a Struts app > and any other Servlet-based app (or HTTP server app for that matter). > > Right? > > Erik > > Saurabh Bhatla wrote: > > >Hi all, > > I have my web application based on struts framework.

java application to struts
Hi all, I have my web application based on struts framework. This application takes some information from the user. I can submit information using jsp but now i want to have a java application that would connect to my webapplication using http connection and submit the information. I know I can do that if I have a servlet. Now my question is how do that with struts. What will be action mapping and all that information. Any suggestions regards saurabh - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
RE: connection pooling
Jim,
I understand most part of it now. the only thing that i dont
understand is how will the connection pooling be handled. I am using
tomcat 5. will the following code(from the link that u sent me) serve
the purpose?

RE: connection pooling
Jim,
I am sorry but I am confused now. Just correct me if I am
wrong I want to call my DAO from my Action class. So the snippet
that you sent me would go in my DAO class in the function
getConnection() (or something like that).
And if what I said is correct then does it mean that I dont need to
have a connection pool class and my webserver would handle everything
for me.
regards
saurabh

Re: connection pooling
David, But i want to make a business layer and call the DAO from there. I think that the links that you have sent me couple presentation layer and database tightly. I know i can use EJB for presentation layer but I dont want that as it would be overkill for the small project I am working on. I want to have a connection pool class initialized at the time the server starts and then all my DAO should get the connection from that pool. Is it possible? I am a beginner in this field and I might not understand it completely. please correct me if i am wrong. regards saurabh - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
connection pooling
Hi all, I have just started working with struts a few days ago, and I understand most of it. The only thing that i dont understand is, if i make a connection pool then where will it be initialized. In servlets I know that it can be done in the init() method but in struts framework there is nothing like an init() method. I have the connection pool class that i have written and i was using in one of my servlets. Now i want to know how to initialize the connection pool object and how to pass that object to all Action classes. Any suggestion would be greatly appreciated. regards saurabh - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
