# UPGRADE FROM 1.0 to 2.0

​

The main change is that the property `$soapClient` in the abstract class `AbstractSoapClientBase` is no more static.

​

**Previously**:

```php

class MyService extends AbstractSoapClientBase

{

    public function CreateQueue(\Api\StructType\ApiCreateQueue $body)

    {

        try {

            $this->setResult(self::getSoapClient()->CreateQueue($body));

            return $this->getResult();

        } catch (\SoapFault $soapFault) {

            $this->saveLastError(__METHOD__, $soapFault);

            return false;

        }

    }

}

```

​

`self::getSoapClient()` was used to access the SoapClient instance.

​

**Now**:

```php

class MyService extends AbstractSoapClientBase

{

    public function CreateQueue(\Api\StructType\ApiCreateQueue $body)

    {

        try {

            $this->setResult($this->getSoapClient()->CreateQueue($body));

            return $this->getResult();

        } catch (\SoapFault $soapFault) {

            $this->saveLastError(__METHOD__, $soapFault);

            return false;

        }

    }

}

```

​

`$this->getSoapClient()` is now used to access the SoapClient instance.
