Where is iws-webapps_6_0.dtd

I am attempting to launch my struts app in Iplanet 6.0.
My web-app.xml shows an error when I try to view giving me an error it cannot find the iws-webapps_6_0.dtd file. I searched the internet and have not found it. Any ideas where i could find it?

Thanks

validate method is not being called

Thanks for all your help.
I found this a while ago but I wanted to close this issue for others use.
Thanks.

The solution is that the Aliaslist.jsp page needed to use message tag instead of an error tag.

Struts

validate method is not being called

What you told me about the Action mapping parameter is correct. And the Input attribute of the Action is correct so not at least the validate() method is beging called. Horray! Thank you very much. However now i'm getting a ClassCastException error inside of my jsp(according to the Stack Trace). Here is the stack trace.

Here is my updated [BOLD]struts-config.xml[/BOLD] file with the added input attributes
I changed the input to the path[BOLD] input="/pages/addNew.jsp [/BOLD]

And Here is the updated validate method for connectionDetailForm
I used the deprecated ActionErrors. add() just incase the difference in ActionMessage was the problem.

/**
* Form bean which represnets a single database connection.
*
* This bean wraps the underlying object ConnectionDetail.
*
* There are two classes in use here, ConnectionDetail and ConnectionDetailForm,
* the latter incapsulates the former. I use this araingement to overcome
* a limitation of the struts framework, namely the nead for form beans to extend
* from ActionForm which inturn has a dependancy on the Servlet API. This causes
* architecturale problems when trying to isolate the SQL bean layer - This class can
* only be instanced with in the Servlet container and is created by struts auto
* magicly and generaly passed in to action handlers. The SQL bean layer neads to work
* with data beans that it can create its self (also we can test it in isolation
* from everything else), or tare it out and reuse it somewhere else.
*
* ConnectionDetailForm is for use in action handlers and jsp's, behind the action
* handler we use ConnectionDetail.

Any Ideas? I think we're getting closer thanks for all your help.

Any other ideas I could try?

Struts

validate method is not being called

Hello,
I'm new to the struts framework. I'm using struts 1.1.
I set up a validate method in my ConnectionDetailForm but when I run /ProccessAddNew action the form the validate() method is never called.

Below is my struts-config.xml file.

<?xml version="1.0" encoding="UTF-8"?>

The Form connectionDetails has the validate method. The way it is supposed to work is that when I add a new Connection with a blank alias the validation should kick in and show me a message.

Below is the ConnectionDetailsForm contents.

public class ConnectionDetailForm extends ActionForm {
private ConnectionDetail cd = new ConnectionDetail();
String alias = "";
String passwordChangesEvery = "";
String usersSwitchEvery = "";
String lastUserSwitch = "";
String nextUserSwitch = "";

String password2 = "";
String password2Start = "";
String password2End = "";
String dbURL = "";
String driver = "";
public void setAlias(String foo) { this.cd.setAlias(foo); }
public String getAlias() { return this.cd.getAlias(); }
public void setPasswordChangesEvery(String foo) { this.cd.setPasswordChangesEvery(foo); }

public String getLastSwitchUser() { return this.cd.getLastUserSwitch(); }

public void setPassword2Start(String foo) { this.cd.setPassword2Start(foo); }

}
return errors;
}

}
}

Can you help me? the validate method is completley ignored.
