InfoPath Dev

Hi,

I have created some forms using Infopath2007 and published them to sharepoint server2007 where office forms server is running. I have created a portal(in Java) from which I need to access these forms.

My requirement is as follows:
1) I need to connect to sharepoint server from my portal by passing the user credentials so that no username/password dialogue box pops up. Is this possible?
2) I need to access all the published forms(I think this is possible because when we publish a form, the URL of the forms are avaliable)
3) I need to retrieve the form instance already filled in by the user and display it. Is there any API/webservices provided? How do we identify that a particular portal user submitted this instance?
4)I need to get the data of a submitted form. Is there any API available for this?

I'm new to this concept and any help would be much appreciated.

Thanks in advance
Jenz

Hi Jenztech,
1) have you looked at the new Single Sign On stuff?
2) yes, use the URL (see my reply to another of your posts)
3) look at the java source code in the SharePoint pages that have XML form opening buttons for some sample code
4) depends on what you need to do with it. there are SharePoint Web methods to do this - have you looked at the SharePoint SDK?
