sessionManager无法解决使用documentum导出操作中java摆动的问题

Question

我在处理documentum **代码2**中的导出操作时面临一个问题。这里代码1是Jbuttons和Jtext的代码，代码3是导出操作的代码。在引起问题的部分中:-

jLabel_messages.setText(te.exportExample(sessionManager,repository,docId,targetLocalDirectory));，我得到第一个参数 sessionManager 的错误消息，该消息说:"sessionManager无法解析"。我试图在代码中实例化sessionManager，如IDFsessionManager sessionManager = null;，但它没有解决问题，错误仍然发生。

谁能帮助我或建议我的变化，我需要做我下面的代码来纠正这个问题?

Code1:导出按钮调用actionevent

jTextField_localDirectory.setBounds(new Rectangle(470, 49, 85, 20));
    jLabel_exportFolder.setText("Export Documents: ");
    jLabel_exportFolder.setBounds(new Rectangle(365, 55, 85, 15));
    jLabel_exportFolder.setHorizontalAlignment(SwingConstants.LEFT);
    jButton_export.setText("Export Files");
    jButton_export.setBounds(new Rectangle(560, 45, 125, 20));
    jButton_export.addActionListener(new ActionListener() {
                public void actionPerformed(ActionEvent e) {
                    jButton_export_actionPerformed(e);
                }
            });

Code2:导出操作的操作处理程序代码:

private void jButton_export_actionPerformed(ActionEvent e)
{
String repository = jTextField_repositoryName.getText();
String docId =m_fileIDs.elementAt(list_id.getSelectedIndex()).toString();
String targetLocalDirectory = jTextField_localDirectory.getText();
TutorialExport te = new TutorialExport(); jLabel_messages.setText(te.exportExample(sessionManager,repository,docId,targetLocalDirectory));
}

代码3:EXPORT Code:

您没有提供太多细节，我也没有太多Java Swing的经验，但是，在我看来，您在实例化变量sessionManager之前试图使用它。

通过DFC在自定义应用程序中实例化Documentum会话管理器的代码如下:

//instantiating client
IDfClient myClient = DfClient.getLocalClient();
// create login info
IDfLoginInfo myLoginInfo = new DfLoginInfo();
myLoginInfo.setUser("user");
myLoginInfo.setPassword("pwd");
// create session manager
IDfSessionManager mySessionManager = myClient.newSessionManager();
mySessionManager.setIdentity("repositoryName", myLoginInfo);
