R – Salesforce.com – Why uploading of Apex class is not working

apex-codeforce.comsalesforce

I have an Apex class (controller) originally developed under Developer Edition and need to upload it to production which is Enterprise Edition.

The upload fails with following message

classes/RenewalController.cls(RenewalController):An error occurred on your page.

package.xml(RenewalController):An object 'RenewalController' of type ApexClass 
was named in manifest but was not found in zipped directory

The same message when I try to use Force.com IDE: Save error: An error occurred on your page.

This class is working under Developer Edition but not with Enterprise.

What can be the problem?

Dmytro, you are correct. Visualforce pages, apex classes, and components must be uploaded in the correct order. Generally the pattern I use is upload the controllers, components, and then visualforce pages.

How to call a method of a class into another class in apex

You can use two approaches:

1.Use Static methods

You cannot use controller2 instance methods here

public class controller2 
{
    public static string method2(string parameter1, string parameter2) {
        // put your static code in here            
        return parameter1+parameter2;
    }
    ...
}

In a separate class file call method2()

// this is your page controller
public class controller1
{
    ...
    public void method1() {
        string returnValue = controller2.method2('Hi ','there');
    }
}

2.Create an instance of the other class

public class controller2 
{
    private int count;
    public controller2(integer c) 
    {
        count = c;
    }

    public string method2(string parameter1, string parameter2) {
        // put your static code in here            
        return parameter1+parameter2+count;
    }
    ...
}

public class controller1
{
    ...
    public void method1() 
    {
        controller2 con2 = new controller2(0);
        string returnValue = con2.method2('Hi ','there');
    }
}

If your methods are in a package with a namespace

string returnValue = mynamespace.controller2.method2();

Deploying from a development org to a new unrelated org without a package

The troubles with a virgin sandboxes is that usually you can't deploy it without a few iterations.

I used the following workflow:

deploy the custom objects which are on relationships with standard objects
deploy standard sObjects
deploy the rest of sObjects
deploy triggers and apex code
deploy VF pages/VF email templates
deploy the rest of metadata

after that I used only migration tool for deployment.

I'd like to suggest you perform deployment of sObjects by one at a time for most significant objects. Also before the deployment please check that all settings of standard objects conform to DevOrg's settings

Also you can try to change API version of metadata.
