Fetching data from another Salesforce organization

InfallibleTechie Admin
Step 1: Generate
Partner WSDL.

Save
the generated Partner WSDL.
Step 2: Generate Apex code using the
generated Partner WSDL.

 

 

Copy the generated code and create a new Apex Class.
Note:
In the generated code do the following changes.
  1. Change
    public partnerSoapSforceCom.DeleteResult[]
    delete(String[] ids)      to public partnerSoapSforceCom.DeleteResult[]
    deleteSObjects(String[] ids)    .
  2. Change
    public partnerSoapSforceCom.UpsertResult[]
    upsert(String externalIDFieldName,sobjectPartnerSoapSforceCom.sObject_x[]
    sObjects)     to public
    partnerSoapSforceCom.UpsertResult[] upsertSObjects(String
    externalIDFieldName,sobjectPartnerSoapSforceCom.sObject_x[] sObjects)    .
  3. Change public
    partnerSoapSforceCom.MergeResult[]
    merge(partnerSoapSforceCom.MergeRequest[] request)     to public
    partnerSoapSforceCom.MergeResult[] mergeSObjects
    (partnerSoapSforceCom.MergeRequest[] request).
  4. Change public
    partnerSoapSforceCom.SaveResult[] update(sobjectPartnerSoapSforceCom.sObject_x[]
    sObjects)     to public partnerSoapSforceCom.SaveResult[] updateSObjects(sobjectPartnerSoapSforceCom.sObject_x[]
    sObjects).
  5. Change public
    partnerSoapSforceCom.UndeleteResult[] undelete(String[] ids)     to public partnerSoapSforceCom.UndeleteResult[]
    undeleteSObjects(String[] ids).

Step 3:  Create visual force page to get the following
details

  • Login
    credentials
  • Object
    Names
  • Field
    Names
  • Records

Sample Code:
<apex:page controller=”sfTosf” >
<!– Javascript –>
<script type = “text/javascript”>
   
window.onload=function()      
    {         
       
document.getElementById(“objs”).style.display = ‘none’;
       
document.getElementById(“fields”).style.display = ‘none’;
       
document.getElementById(“records”).style.display = ‘none’;
    };
   
    function
callObjects()
    {
       
document.getElementById(“objs”).style.display = ”;
        CallLogin();
    }
    function
callFields()
    {
       
document.getElementById(“fields”).style.display = ”;
       
CallShowFields();
    }
   
    function
