visualforce page not displaying data pulled in through rest call

I have a visual force page as a hyperlink on account details page. I would like to display information about contracts related to that particalar account through the page. There is a catch through, users accessing the page does not have access to contract object, so I built a rest call to call the page as me everytime they try to access the page. I checked the debug logs, contract details are being pulled in, but are all the user can see is blank spaces on vf page. I am posting my code, please let me know what I am doing wrong. 

Vf page: 
<apex:page standardController="Account" extensions="ContractdetailsfromaccountController" >
    
    <apex:outputPanel >
        <div style="float:Left;margin-top:2em;font-family:  sans-serif;font-size:12px;/*width:50%;*/">

Would really appreciate any help in this.

Hey Krishna
It is a bit out of topic question, even if user dont have profile level security , still they can see the records in visualforce, not sure why you used soap here to get the records if it's from the same salesforce instance.
Could you elaborate on the requirement ?

Thanks,

Hey Shiva,

Thanks for the response. I should have been clear. The object is part of a managed package, hence, users without license cannot read the data from the object. 
On a positive note. I was able to figure the issue out, it is working now. I wrote a wrapper class and added field values to variables and used them in vf page. It is working now. 

Thanks,

Was it Getter setter issue then ? Cool
Krishna VegirajuKrishna Vegiraju
Not getter setter issue to be precise. Like you can see in the code I posted, querying the object through api and feeding it to controller. The issue was with how outputtext was not able to read that data. So, I had to decalre each field as a variable(getters and setters) and then use those variables in output text instead of the actual fields itself. 

Thanks,

Ok Krishna.. cool
