просто следуйте документации ogone.Если вы хотите использовать прямую ссылку, я предлагаю использовать пружинный RestTemplate.
<!-- rest template -->
<bean class="org.springframework.web.client.RestTemplate" id="restTemplate">
<property name="messageConverters">
<list>
<ref bean="formMessageConverter" />
<ref bean="stringMessageConverter" />
</list>
</property>
</bean>
<bean class="org.springframework.http.converter.StringHttpMessageConverter"
id="stringMessageConverter"></bean>
<bean class="org.springframework.http.converter.FormHttpMessageConverter"
id="formMessageConverter"></bean>
<bean class="DirectLinkTemplateImpl" id="directLinkTemplate">
<property name="restTemplate" ref="restTemplate"></property>
<property name="url"
value="https://secure.ogone.com/ncol/test/orderdirect.asp"></property>
<property name="pspId" value="YOR PSP ID"></property>
<property name="userId" value="userID"></property>
<property name="pswd" value="pass"></property>
<property name="shaPassphrase" value="shaPassphrase"></property>
</bean>
Затем используйте код, подобный следующему, чтобы отправить сообщение в ogone

Я еще не закончилс реализацией, но, по крайней мере, часть "post to ogone" уже работаетЯ постараюсь опубликовать полный шаблон DirectLinkTemplate в своем блоге после его завершения и очистки.
