Which Adaptor is appropriate please suggest

Question

Hi All,
I have the following scenario and want your suggestions:
A web based applicaiton (say A) to create customer need to integrate with another web based applicaiton (say B) which uses the customer details to display of Applicaiton A... wondering do I need to go for SOAP adaptor/HTTP adaptor or do I need to integrate these two applicaitons at data base level using JDBC adaptor?
What are the steps/any documentation to get the data from web site to SAP PI when User clicks submit button?
Please suggest.
Thanks
Rajeev

>>> but my questtion is what needs to be done at Applicaiton A side to create Input and post the data in the SAP PI URL... As they are using the web client provided by the Application provider..Do they have to write code at the submit button of the web page? If so they have to customnise the code delivered by the provider? How it works.. Its been first time going through this...
Yes, if you create webservice by creating soap sender and give WSDL, then they will have to write webservice client program in java or any language to access your webservice. This program will be called in their side at the time of hitting submit button of the web page.
For this you have to go through soap sender sdn documents.
or  As I already mentioned, create HTTP sender and provide your payload structure and url as we discussed in the above replies. A has to create coding to post HTTP using the url during submit hit button on their web page.
>>Do they pass all the values in the URL or to the URL?
This is client A's problem. Why do you worry?  There are plenty of documents to do http post.. The below coding is simple snippet..
Search google for plenty of documents...
try {
    // Construct data
    String data = URLEncoder.encode("key1", "UTF-8") + "=" + URLEncoder.encode("value1", "UTF-8");
    data += "&" + URLEncoder.encode("key2", "UTF-8") + "=" + URLEncoder.encode("value2", "UTF-8");
    // Send data
    URL url = new URL("http://hostname:80/cgi");
    URLConnection conn = url.openConnection();
    conn.setDoOutput(true);
    OutputStreamWriter wr = new OutputStreamWriter(conn.getOutputStream());
    wr.write(data);
    wr.flush();
    // Get the response
    BufferedReader rd = new BufferedReader(new InputStreamReader(conn.getInputStream()));
    String line;
    while ((line = rd.readLine()) != null) {
        // Process line...
    wr.close();
    rd.close();
} catch (Exception e) {
>>Is it possible to use SOAP adaptor instead of HTTP adaptor? so that I can use AAE in the entire scenario. Applicaiton A is a web client interface through which Customers are created.If I need to use HTTP Adaptor, do I need to create HTTP Sender Adaptor and sender Aggrement ?
Yes, if you host webservice using soap sender adaptor. Already answered above ...
>> If I need to use HTTP Adaptor, do I need to create HTTP Sender Adaptor and sender Aggrement ?
no. Http adaptor is in abap stack. so you dont need sender agreement.
