I need to call  an external service from VF. I am trying to generate apex classes from WSDL and running into issues for import and includes as shown below.


Failed to parse wsdl: Unknown element: import

Failed to parse wsdl: Found schema import from location CLiteratureItems.xsd. External schema import not supported

Failed to parse wsdl: Unsupported Schema element found http://www.w3.org/2001/XMLSchema:include. At: 7:57


I have seen some posts on these and suggestion is to rework on the wsdl to bring in the external wsdl's into the same. 


Is there any documentation on how to get this resolved. 


Really appreciate your help.

Eclipse creates WSDL version 1.5. But the latest version is 2.0


Is there any other tools available?

We are trying to access the external API web service and it requires Username Token in the SOAP header. We were able to generate apex script based on the web service description (we had to simplify the wsdl file and drop some methods to make it fit into 100k chars), but do not see how we can add our security header to the stub before making web service method invokations. We see that HTTP output headers are public in the Apex code of the stub. Is it possible for SF to make the SOAP headers public or suggest an idea how to add our security header?

I'm learning to write apex code for calling out to external webservices. I started out with strikeIrons zipcode lookup. I'm new to webservices, so please help me out. Is this how I should go abt doing it?

1. Get WSDL. Generate apex.(done)

2. Created county__c field in account sObject(done)

3. Write before insert, before update trigger that passes the zipcode to CountyLookupClass.(done)

4. CountyLookupClass calls the @future webservice, passes the authentication parameters(username,password) and also the zipcode. 

5. StrikeIron authenticates. Returns county. 

6. Need to map the returned county name to Account.County__c field, so that it is added/inserted to the force.com database. 


Am I right? Here is the trigger


trigger CountyLookupTrigger on Account (before insert, before update) {

for(Account a: Trigger.new)



 Apex class in invoke webservice


public class CountyLookupClass {

public static void CallWS(String zcode){
//pass zipcode to ZipINfo
//get info
//parse to county__c
//create the stub
ZipLookup.ZipInfoSoap zipl = new ZipLookup.ZipInfoSoap();

//instantiate and setup authentication information

zipl.LicenseInfo = new ZipUser.LicenseInfo();
zipl.LicenseInfo.RegisteredUser = new ZipUser.RegisteredUser();
zipl.LicenseInfo.RegisteredUser.UserID = 'withoutme@gmail.com';
//call web service
ZipLookup.SIWsOutputOfZipInfoResult zz = zipl.GetCityState('94131');
String c = zz.ServiceResult.Code;
System.debug('Codeis' + c);
//ZipLookup.ZipInfoResult z = zipl.GetCityState('85281').;






How do I test this? Am I doing it right?




And the apex from wsdl2apex.wsdl fom http://www.strikeiron.com/productdetail.aspx?p=436

I am new to SalesForce. We have a requirement to integrate our service with the salesforce.

In  in the Apex refrence pdf(salesforce_apex_language_reference.pdf), they tell to import the wsdl file & map the end point in Remote Setting.

Can any one please give me the sample wsdl with the end point. I tried wsdl like "AmazonWebServices.wsdl, AmazonS3.wsdl, GoogleSearch.wsdl,..."

Since those uses rpc which is not supoorted in salesforce I was not able to import it to generate Apex class.

Can any give me some inputs or some links for service end points which uses 'doucment' type instead of 'rpc'.

I am generating apex from a wsdl using wsdl2apex.  The wsdl has complex data type that contains an Apex reserve word "Map"


<complexType name="Map">


<element maxOccurs="unbounded" minOccurs="0" name="item" type="apachesoap:mapItem"/>




This generates a class in apex:


 public class Map {

public ntta_login.mapItem[] item;

private String[] item_type_info = new String[]{'item','http://xml.apache.org/xml-soap','mapItem','0','-1','false'};

private String[] apex_schema_type_info = new String[]{'http://xml.apache.org/xml-soap','true'};

private String[] field_order_type_info = new String[]{'item'};



Apex validation fails with "unexpected token class" because of the reserve word Map being used.


I try chaning the class to Map_x but the callback fails from the webservice with:

service callout failed: Unable to parse callout response. Apex type not found for element item


Is there a workaround that I can use besides changing the wsdl definition source system?



Hi all-


I'm trying to convert another WSDL and i'm getting the following error.  What is the supported type for a byte?


Error: Unsupported schema type: {http://www.w3.org/2001/XMLSchema}byte


Hi all-


I'm wondering if someone can help me figure out the solution to my problem.  I generated an apex class from the WSDL class generator, and this is part of the output. However, I have been told that I will need to ensure the the SOAP responses are described in the WSDL.  I'm not a SOAP expert so I don't know where to begin...  So, I have posted the two types of responses that come back from our web service provider as well as how its defined in the WSDL.   ANY help is greatly appreciated...



public csCallCenterWS.CreateNewAccountResult_element CreateNewAccount(String strUser,String strPin,Integer lngSiteID,String strFirstName,String strLastName,String strAccountName,String strAccountType,String strAddress1,String strAddress2,String strCity,String strState,String strZip,String strEmail,String strHomePhone) { csCallCenterWS.CreateNewAccount_element request_x = new csCallCenterWS.CreateNewAccount_element(); csCallCenterWS.CreateNewAccountResponse_element response_x; request_x.strUser = strUser; request_x.strPin = strPin; request_x.lngSiteID = lngSiteID; request_x.strFirstName = strFirstName; request_x.strLastName = strLastName; request_x.strAccountName = strAccountName; request_x.strAccountType = strAccountType; request_x.strAddress1 = strAddress1; request_x.strAddress2 = strAddress2; request_x.strCity = strCity; request_x.strState = strState; request_x.strZip = strZip; request_x.strEmail = strEmail; request_x.strHomePhone = strHomePhone; Map<String, csCallCenterWS.CreateNewAccountResponse_element> response_map_x = new Map<String, csCallCenterWS.CreateNewAccountResponse_element>(); response_map_x.put('response_x', response_x); WebServiceCallout.invoke( this, request_x, response_map_x, new String[]{endpoint_x, 'http://centershift.com/csCallCenter/csCallCenterService/CreateNewAccount', 'http://centershift.com/csCallCenter/csCallCenterService', 'CreateNewAccount', 'http://centershift.com/csCallCenter/csCallCenterService', 'CreateNewAccountResponse', 'csCallCenterWS.CreateNewAccountResponse_element'} ); response_x = response_map_x.get('response_x'); return response_x.CreateNewAccountResult; }

Hi there

Does Apex support Secure Web Services. I need to consume an external WS, for one which need to be authenticated.
Authentication is via another WS, which accepts a X509 cert in the request and returns a Binary Security Token in the response.

This token needs to be embedded in all further requests, like this
<wsu:Timestamp wsu:Id="Timestamp-2b27a32b-ca9c-4405-b377-4444f63c8f29">

In .NET , this can be written as

AuthPlusWS.InteractiveWSWse service = new AuthPlusWS.InteractiveWSWse();
// Add the secure token to the secured service
service.RequestSoapContext.Security.MustUnderstand = false;

Is there a way to do this in apex ?

I have been working under the impression that Salesforce SOA does not support WSS security tokens while making external Web Service calls in Apex.  I haven't seen anything in the docs about SOA supporting WSS.

I wanted to get confirmation that this is accurate, that SOA cannot create and include WSS 1.0 security tokens in requests to Web Services.
