i write a visualforce page with code

{!$Api.Session_ID}

i copied the session Id.and used curl and run the command

 curl --header "Authorization : Bearer 00D90000000oX2G!AR8AQF4bfKL.F59U3YiDpt3WY5McM6lhzPhoQzTgkpuBUi1gbEMFXlWgCfq4QmufGh.Zw.VlGN4HCCG0S93qlcy671cQ6xcG" https://mydevorg-dev-ed--c.salesforce.com/services/data/v29.0/

and getting error bash:

!AR8AQF4bfKL.F59U3YiDpt3WY5McM6lhzPhoQzTgkpuBUi1gbEMFXlWgCfq4QmufGh.Zw.VlGN4HCCG0S93qlcy671cQ6xcG": event not found

then i used chrome extension Advanced rest client and send the request

GET https://mydevorg-dev-ed--c.salesforce.com/services/data/v29.0/

Request Header Authorization: Bearer 00D90000000oX2G!AR8AQF4bfKL.F59U3YiDpt3WY5McM6lhzPhoQzTgkpuBUi1gbEMFXlWgCfq4QmufGh.Zw.VlGN4HCCG0S93qlcy671cQ6xcG

and i am getting No response after one minute .can some body tell me why i am unable to call rest api ??

i have a visualforce page that source code is

as i can see

chatter.getFeed().showMoreFeedItems(this, {paginationToken: dayStart.toISOString()});

without calling apex they are getting chatter.getFeed(). is there any link or documentation on chatter for getting feed using javascript with various filters please guideline.

i have to get some data using SOAP api from one org to another .so i generated Enterprise wsdl file of one organization . it contains some fields with specified type as type=xsd:anyType. because apex doesn't support xsd:anyType thats why i changed it to xsd:string .ok it will generate some apex classes .i want to know is it the proper way.for handling anyType or we should do some thing else .Please guideline

i write a Batch apex.i write an execute method .which is using a static variable of another class.because it is shhared.any one can use it and change it.

public void execute(Database.BatchableContext BC, List<sObject> scope){

     x=GMirror.x;

     ...........

     ...........

         .........

y =GMirror.x; 

}

i want to know each batch of 5 in my case will run in transaction or means at this time only this method is running nothing else or in other words i want to know if using another class's method execution  in between time first statement execute

     x=GMirror.x;

and second statement 

y =GMirror.x; 

its possible by another parallel execution of another class's method that  these value of GMirror.x get changed ??

 these execution  this necessary that no one changed value of GMirror.x or value of GMirror.x can be changed by another parallel execution.Please clarify .

hi i am sending only a single Http Request in Batch but still facing error System.CalloutException: You have uncommitted work pending. Please commit or rollback before calling out

my authsub page is

<apex:page controller="AuthSubController" showHeader="false">
<head><title>Hello World</title>
<meta name="google-site-verification" content="XCzApP9fdbR3auxPHd3-X0g7uCNbrXZDQU_jm5GHXLI" />
</head>
          <apex:outputPanel rendered="{!$CurrentPage.parameters.token != null}"> 
The one time use token is :<b>{!$CurrentPage.parameters.token}</b>
            <br />
Record to update is {!$CurrentPage.parameters.id}
<br />
URL to update is {!hello}
<apex:form >
<apex:commandbutton action="{!exchangeRequestToken}"
                oncomplete="window.close();" value="Request Session token" />
        </apex:form>
        </apex:outputPanel>
</apex:page>
in my authsub page controller class is AuthSubController
if you AuthSubController class there is a constructor and for highlighting i am pasting constructor here

public AuthSubController(){

 if ( ApexPages.currentPage().getParameters().get('token') != null) { 
          //  string sessToken = 
            // AuthSubUtil.exchangeForSessionToken( 
              //  ApexPages.currentPage().getParameters().get('token'));
 GoogSession__c session = new googSession__c(id=
                ApexPages.currentPage().getParameters().get('url').substring(5),
                 AuthSubSessionToken__c = null );
            
       //     update session;
}
}

if i make these lines commented(as shown in constructor ) then there is no (Authorization Required).if uncommented code of constructor is given below:

public AuthSubController(){

 if ( ApexPages.currentPage().getParameters().get('token') != null) { 
            string sessToken = 
             AuthSubUtil.exchangeForSessionToken( 
                ApexPages.currentPage().getParameters().get('token'));
 GoogSession__c session = new googSession__c(id=
                ApexPages.currentPage().getParameters().get('url').substring(5),
                 AuthSubSessionToken__c = null );
            
            update session;
}
}

in this case there is Authorization required error.i gave all permission to GoogSeession__c in public access settings of site for sure.probably main problem is with this line.
error come when i redirected to authsub home page

  string sessToken = 
             AuthSubUtil.exchangeForSessionToken( 
                ApexPages.currentPage().getParameters().get('token'));

can any one please help me how to remove this Authorization Required error.please dont look at above two big code segments these are only for completeness of question main is thes constructor code where i am getting error.

and My createTimeLine function code is 

public static void createTimeLine(List<sObject> objList,Map<String,String> contentMap){

String timelineRes = doApiCall('xyzzz','POST','https://www.googleapis.com/mirror/v1/timeline','xxxxxxxxx');

}

doApiCall code is 

public static String doAPICall(String postBody, String method, String endPoint, String accessToken){

HttpRequest req = new HttpRequest();
Http http = new Http();
HttpResponse res;

req.setEndpoint(endPoint);
req.setMethod(method);
req.setHeader('Content-Type','application/json');

if(method == 'POST' || method == 'PUT')
req.setBody(postBody);
req.setHeader('Authorization','Bearer ' + accessToken);
res = http.send(req);
String result = res.getBody();
System.debug('status code is '+res.getStatus());
System.debug('result is'+res.getBody());
return result;
}

and the Mock class code response is 

@isTest
global class MirrorMockTimelinePostImpl implements HTTPCalloutMock {
global HTTPResponse respond(HTTPRequest req) {
// Optionally, only send a mock response for a specific endpoint
// and method.
System.assertEquals('https://www.googleapis.com/mirror/v1/timeline', req.getEndpoint());
System.assertEquals('POST', req.getMethod());
System.assert(req.getHeader('Authorization').startsWith('Bearer'));

// Create a fake response
HttpResponse res = new HttpResponse();
res.setHeader('Content-Type', 'application/json');
res.setBody('{"kind":"mirror#timelineItem", "id":"mockid", "created":"2013-07-31T12:07:34.882Z", "updated":"2013-07-31T12:07:34.882Z", "etag":"\\"ZECOuWdXUAqVdpmYErDm2-91GmY/NVMWuR8LJyCKttsmne9R4K8n7YI\\"", "text": "New Lead: OauthCheck EarlyAm, Google, Inc., (234) 567-8900"}');
res.setStatusCode(200);
return res;
}
}

and i am unable to figure it out how using only one callout its throwing an error ?? Please help

i am calling batch apex from a trigger after in sert function i am getting this error from line 

String timelineRes = doApiCall(body,'POST','https://www.googleapis.com/mirror/v1/timeline',userSettings.AccessToken__c);

i am not using any DML statement after doApiCall function as you can see . but why i am facing trhis error ??Please guideline to resolve it.

riggeri am testing a trigger.i am calling this method

  GMirrorUtil.createTimeLine(Trigger.new, contentMap);

My create timeline function is

       for(Id user_id : userMap.keySet()){
         GlassUserApiSettings__c userSettings = GlassUserApiSettings__c.getValues(user_id);
        if(userSettings == null)
         { User u =userMap.get(user_id);
            u.Authorize__c = false;
           update u;  
         }
          else userSettingsMap.put(user_id,userSettings);

                  }
           }
         }          
    }

but when i initialize prepare String body='{"html":"'+type+':'+ '"'+obj.getSObject('CreatedBy')+' '+obj.getSObject('CreatedBy')+'

'+obj.get(contentMap.get('Content'))+'

'+ ' "}'; i check it in debug logs its giving me null for getSObject('CreatedBy'); i inserted it in my test class thats why trigger invoked and i am using afterinsert event in trigger . can any one please tell why its giving me null ??
