I have to Add Product Records from a Custom Package_Product__c Object that has lookup to Product2, into the Product Related list on Opportunity Detail Page 

I have Custom Link on the Opportunity Detail Page. This link Opens a VF Page with Drop downlist that contains records from a CUstom Object Package_Header__c (). Each Package have more than one records from the custom object Package_Products__c. When a user select the package from the Dropdown, all the products in the package are added to the Product Related List on the Opprotunity detail page.

I have completed the first part here, where I have inserted the Records Package_Header__c Records into the dropdown on the basis of Legal_entity__c field (it represent countries). Also I have queried the records from the custom Object Package_Products__c. But My main Problem is how to insert the records into Product Related List (This related list is Standard one and comes by default with every opportunity record and lists the products associated with the opportunity)

The coded for it is written below: I am using Extension = packageSelectionController  and Opportunity as Standard Controller

public string legalEntity;

public Package_Header__c pobj = new Package_Header__c();

String id = ApexPages.currentPage().getParameters().get('id'); opp = [

legalEntity = opp.Legal_Entity__c;

}

//Create the picklist on the VF Page and populate it withy the records from Package_Header__c

String piValues;

List<SelectOption> options = new List<SelectOption>();options.add(

{

}

}

}

}

}

//create a list of package products that holds the products for a particular package,(used in the SelectPackage method below)

public List<Package_Product__c> packageProduct = new List<Package_Product__c>();

public List<OpportunityLineItem> oplItem = new List<OpportunityLineItem>();

//Select the Required fields from the Package_Product__c Onthe basis of selected value of the picklist for Packages

String packageId = ApexPages.currentPage().getParameters().get(piValues);

Sort_Order__c, Opt__c, Smpl__c, Product2__r.Id, Product2__r.ProductCode From Package_Product__c

//variables for holding then field values from the

String productName;

String productCode;

String quantity;

String discount;

String fixedPrice;

String Opt;

//For loop for assigning the retieved values for each record in the above query to the variables declared above.

oplItem.discount = packageProduct.Discount__c;

}

opportunityPage.setRedirect(true);

}

opportunityPage.setRedirect(true);

}

}

I am designing a VF Page for force.com sites This page is actually a Form to be filled by te user for submitting queries.

Before storing the Contact Record that the user enter in the form, I have to check weather the Email entered by the user already exist. If it exist, then just case will be created and it will be linked with the existing Contact having the same Email Id that the user entered. If the Email entered by the user doesn't exist, I have to create both the Contact and the Case. I need to wriete the logic with in my Apex Class and don't need the trigger for it. I have completed this second part, but don't know how to implement the first one. The code for this second part that creates both the contacts and case without checking the Email is listed below:

public String firstName{set; get;}

public String title{set; get;}

public String emailId{set; get;}

public String firstAddress{set; get;}

public String cityOrTown{set; get;}

public String postalCode{set; get;}

//Fields that goes only to the Case Record

public String lotNumber{set; get;}

//This is the code where I am trying to search for Duplicate Records.

List<Contact> oldContacts = [Select Email From Contact];

{ // Can't understand WHY I NEED This Bracket here. If I don't give it, It will give me the error -

//Error: Compile Error: expecting right curly bracket, found 'for' at line 60 column 4

//Here I have to call the method -- public PageReference saveRecords() written below, to save the Contact

//Information if duplicate Email Doesn't exist

saveRecords();//This gives me the error -- System.Exception: DML currently not allowed.

}

}

try

{

contactToStore.FirstName = firstName;

contactToStore.LastName = lastName;

contactToStore.Phone = phoneNumber;

contactToStore.Email = emailId;

contactToStore.MailingCity = cityOrTown;

contactToStore.MailingState = state;

contactToStore.MailingPostalCode = postalCode;

contactToStore.MailingCountry = String.valueOf(country);

insert contactToStore;

accountToCreate.Legal_Entity__c = String.valueOf(country);

accountToCreate.PostalCode__c = postalCode;

//new Object of type Case Standard Object

caseToCreate.ContactId = contactToStore.id;

caseToCreate.AccountId = tempAccount.id;

caseToCreate.Serial_Number__c = catalogNumber;

caseToCreate.Lot_Number__c = lotNumber;

caseToCreate.Product_Code__c = productName;

caseToCreate.Description = queryBox;

}

{

ApexPages.addMessages(e);

}

}

I have main problem with the following section of the code from above:

//This is the code where I am trying to search for Duplicate Records.

List<Contact> oldContacts = [Select Email From Contact];

{ // Can't understand WHY I NEED This Bracket here. If I don't give it, It will give me the error -

//Error: Compile Error: expecting right curly bracket, found 'for' at line 60 column 4 -- Can anyone tell me why I need this bracket  //here

//Here I have to call the method -- public PageReference saveRecords() written ABOVE, to save the Contact

//Information if duplicate Email Doesn't exist

saveRecords();//This gives me the error -- System.Exception: DML currently not allowed.

}

}

Is there anyone who can help me to search for duplicate Email record and save the contact detail if email record don't exists.

I am creating a public Web form in Visual Force for the Force.com site. The user is not logged in. When he fill the form and click the submit button,  the form will create the a contact and Account records (under Contact and Account Standard object), and create a case for that contact(under case standard object).

I am able to create the contact but not able to create and  insert the case for that contact.

The controller code I  am using is listed below:

public class TechnicalServiceController {
   
    public String companyName{set; get;}

    public String state{set; get;}
    public String postalCode{set; get;}
    public String country{set; get;}

For the code block ab ove:

Contact and Account are Lookupfields on Case record  but in my controller/webpage these are text fields and I am trying to store these text fields in the above 2 lookup fields

when I try to store them in the corrresponding fields on the case, it gives me following error message:
Error: Illegal assignment from String to SOBJECT

Is there anyone who can help me on it. I am not using Web to case because in that case I have to display
the fields from my case object on the web page which is not required as some fields are picklist on my webpage and they
are stored as text on case object record.

Also I need to insert the Contact and Case Related List on the Account Record; And Cased Related list in the Contact record for the corresponding Account, Contact , and Case  I create.
