Accessing javascript using HttpClient API

Hi,
I am using HttpClient API to access the content of page.Using that API
I am able to retrive the content of the first page(The page Prior to Login).
Now I want to login with user id and password.I have tried with PostMethod() but the content(in HtML Form) that I am getting is not of the next page but of the same page i.e. I am unable to login.
I have seen the html content of the first page(by View Source from Browser) and there in the form tag on onsubmit event there is a call to a javascript function which is encrypting the password field.
Can any body let me know how to deal with this type of situation or how to access javascript functions through HttpClient API.
Thanks
Anupam Sarkar

hi,
i have the same problem. i want to reach a url that has two parameters sent from a javascript function;
+function doPost(eventTarget, eventArgument) {+
+if (!theForm.onsubmit || (theForm.onsubmit() != false)) {+
theForm._ET.value = eventTarget;
theForm._EA.value = eventArgument;
theForm.submit();
+}+
i tried to write a java code that appends values wtih namevaluepair and send them to base url with setrequestbody method;
     HttpClient client = new HttpClient();
+          +
+     String actionURL = "http://mevzuat.basbakanlik.gov.tr";+
+          +
+     PostMethod method = new PostMethod();+
+          +
+     NameValuePair[] postData = {+
new NameValuePair("aspnetForm._ET.value","ctl00$Menu1"),
new NameValuePair("aspnetForm._EA.value","~/AlfabetikFihristler.aspx"),
+                         };+
+               +
+     method.setPath(actionURL);+
+     method.setRequestBody(postData);+
+          +
+     int status = client.executeMethod(method);+
+.+
+.+
+.+
this code gives a warning;
Feb 13, 2008 9:05:09 PM org.apache.commons.httpclient.HttpMethodBase processResponseHeaders
WARNING: Cookie rejected: "$Version=0; ASP.NET_SessionId=fa4pnl55x3wxy2n2psorpdmu; $Path=/". Illegal path attribute "/". Path of origin: "http://mevzuat.basbakanlik.gov.tr"
and it does not recognize the parameters that i have sent and gets the base url content only.
i am very new to this subject and any help that can fix my problem or shows me the way to solve my problem is appreciated.
thanks...

    1. Login to the website using Login/Password (I have valid login/password)
    2. Two options (links) are there (a) Report (b) Search [I am chosing report option]
    3. Newly opened window shows two tabs (a) Today (b) From & To [I am selection Today tab]
    4. Every tab has two radio button (a) File (b) Destination [Destination is selected by me]
    5. When Search button is pressed. A link gets created when that link is clicked file download popup is opened which allows facility to open/save the file.
    All these 5 step are to be followed in a java program to download the file. Please help in doing the same.

    to implement document rating functionality inside Sharepoint app. The host web contain document library (“Documents”) and from apps we need to rate each document. The rating functionality working fine with CQWP in team site  using
    JavaScript Object Model API.
    But the same code is not working inside apps and giving error:-
    If we are using app context than error will be:-
    "List does not exist.

    Hi,
    According to your post, my understanding is that you want to update list column in SharePoint hosted apps using JavaScript Client Object Model.
    Based on the error message, it seems not retrieve the list object in context. I suggest you debug the code step by step using Internet Explorer Developer Tools to
    find the problem.
    Here are some demos about using JavaScript Client Object Model in SharePoint hosted app:

  • Access KM using API as predefined user

    Hello, dear experts!
    Currently I am going to use KM as file storage for my application. I want to prevent direct access to KM content for all users and allow them to upload and download files only using my application.
    The problem is:
    I use not context of current user but some user found in UME.
    IUser user = UMFactory.getUserFactory().getUserByLogonID("Administrator");
    com.sapportals.portal.security.usermanagement.IUser ep5User = portalUserFactory.getEP5User(user);
    context = new ResourceContext(ep5User);
    When I try to operate KM (for instance create new folder) I get error: "User <Administrator> is not authenticated"
    But user "Administrator" has all rights to access KM.
    Is it possible to access KM using API as different user? Or is there another way to solve the problem?
    Best regards,
    Anton.

    Hi, Praveen!
    Thank you for your answer. Your code works fine!
    But when I created my own service user "service_user" under Content Management  -> Utilities -> System Principals I cannot get resource context even after restarting servlet engine.
    I get an exception java.security.PrivilegedActionException: com.sapportals.wcm.repository.ResourceException: User management exception: Could not get service user "service_user".
    This user has the same permissions as "cmadmin_service".
    Also user with the same name was created in UME.
    May be I should execute some additional administrating task?
    Best regards,
    Anton.

    Hi,
    I am trying to access my gmail account with JavaMail API. I am able to access it using pop3s but not with IMAP.
    I have used following details:

  • Using Jakarta HttpClient API for HTTPS file upload

    Any code sample on how to upload a file via the Jakarta HttpClient API?
    I tried the PostMethod, not sure I used it right, got response msg from the server response code 301, which indicated the file had been permanently moved. What did that mean? Besides, I didn't see PutMethod have a way to specify the target uploaded file filename, it only take a File object.
    Tried the PutMethod as well, but the method I though I can use was "depreciated".
    Any idea?
    jml

    I did. The sample code use the PutMethod and specify the file object. But when I use the similar code, I got 301, which means "File permanently moved". Not sure what that mean.

  • Javascript Variables on Form Login using HttpClient

    Hi,
    I am currently using HttpClient to log onto a forum. As of now I am successfully able to submit a form, which authenticates me, and then takes me to a redirect page(where it welcomes me, stating my username) and then redirects me to the index. On inspecting the code, I saw that some javascript variables are set based on the cookies. However, the httpclient is unable to do this redirection on its own and hence the javascript variables are not getting set and when I subsequently open a new get connection to the index it does not have those javascript variables set and I lose the session.
    I hope I've made my problem clear. Is there any way I could set those javascript variables myself?
    Thanks.

    some javascript variables are set based on the cookiesThen just send those cookies along with the request. The session is usually maintained through a cookie with some unique identifier. You should have retrieved this cookie in the response of the login request.

    The same Global Structure is in the Sender Query and the Target Query
    Question:
    Is there any other way to RRI on structure elements within a sender query to a target query using:
    BADI's, ABAP or any other method.
    Thank you.
    Simon

    Hi SDN Community,
    At the time of asking this question there were not many examples of BADI for RRI's.  I now see a number of examples we can use.
    Thank you.

  • Low level disk access using win API libraries

    Hello All,
    One of my project requires "low level access to the drives (usually pen Drive)' for analysis. I think this is possible using WIN API functions, i tried to read using kernal32.dll but i am unable to complete the task effectively, since i dont have sufficient exposure to text oriented languages. Basically i need to read the memory as it is stored, just like stream of bytes. Could any one guide me how do i proceed inorder to get rid of this.
    thank you.

    Unfortunately no. You cannot mix both high and low level on the same screen. You'll probably have to draw it out yourself and capture user input, unless you're willing to use textboxes.
    Or.. i suppose you can try using customItems for all your "coloring" instead?

  • Problem when selecting PublishingRollupImage using REST API using Javascript ?

    Hii Guys,
    I am developing  a listing page of News using REST, the custom list contains Title, PublishingRollupImage, and other fields which is provided in the $select
    http://xyz/_api/web/lists/getbytitle('News')/Items?$select=Title,Link,PublishingRollupImage
    the column "PublishingRollupImage" is there and i can return the result by using normal JavaScript API with CAML query.
    but REST calling while specifying this column is failing with this error
    The field or property 'PublishingRollupImage' does not exist
    Microsoft.SharePoint.Client.InvalidClientQueryException
    please note that this is not the (hyperlink/image) field,
    its an existing site columns (publishing image)

    Hi,
    According to your post, my understanding is that you want to get Rollup Image data using REST API.
    Per my knowledge, we can’t get it using REST API.
    We can use Client Object Model to achieve it, the following code snippet for your reference:
    var ctx = new SP.ClientContext();
    var items = ctx.get_web().get_lists().getByTitle('Pages').getItems(new SP.CamlQuery());
    ctx.load(items);
    ctx.executeQueryAsync(function() {
    // Get the first items rollup image, just as an example
    var rollupImage = items.getItemAtIndex(0).get_item('PublishingRollupImage');
    console.log(rollupImage);
    If you still want to use the REST API, we can customize a We Service to achieve it.

    I see your thread is still unanswered, were you able to resolve the problem yourself (if so can you share with others who may have the same problem)? If so can you add anymore details which may help someone else to find an answer?  Or is it ok to mark this post as assumed answered?
