将文档设置为Java类中的全局属性,不工作

在我的XPAGE应用程序中,我有一个Java类,我想将文档设置为全局属性,并在我的方法中重复使用。该文档表示Notes配置文档,我只希望执行一次查找。不幸的是,它没有按预期工作。也许有人能引导我去正确的过程?

首先,我建立了一个管理bean:

<managed-bean>
    <managed-bean-name>emplDataMining</managed-bean-name>
    <managed-bean-class>se.bank.employeeApp.utils.EmployeeDataMining</managed-bean-class>
    <managed-bean-scope>view</managed-bean-scope>
</managed-bean>

我的类包含几个方法,这些方法将转到不同的系统。系统的所有URL都存储在Notes配置文档中,我只想加载一次,然后在这些方法中重复使用。

public class EmployeeDataMining implements Serializable{

    private static final long serialVersionUID = 1L;
    private Document configuration;

    //constructor class. not so very special, so I wont post it

    public void getConfiguration(){
        //setting up database and view
        //only 1 document stored in the view so I can hard-code the reference
        configuration = vw.getDocumentByKey("ConfigDocument", true);
        //... rest of code e.g. setting up httpclient, JSONobj
    }

    public void collectDataFromSystemX(CloseableHttpClient httpclient, Employee employee, JSONObject JSONobj){
        //I wont post all of my code  
        HttpPost httpPost = new HttpPost(this.configuration.getItemValueString("urlSystemX"));
        //this.configuration is null :-?
        //..rest of code
    }

    public void collectDataFromSystemY(CloseableHttpClient httpclient, Employee employee, JSONObject JSONobj){
        //I wont post all of my code  
        HttpPost httpPost = new HttpPost(this.configuration.getItemValueString("urlSystemY"));
        //this.configuration is null :-?
        //..rest of code
    }

}

我的代码是从ssjs启动的:

emplDataMining.getConfiguration(); 
emplDataMining.collectDataFromSystemX(//passing in the variables which are setup in getConfiguration method)

所以我主要关心的是配置文件文档没有在方法之间正确地设置或交换。

有人能告诉我我忽略了什么吗?
