我在处理 documentum ** 代码 2** 中的导出操作的操作处理程序代码中遇到问题。这里代码 1是 Jbuttons 和 Jtext 的代码,代码 3是导出操作的代码。在导致问题的部分中:-
jLabel_messages.setText(te.exportExample(sessionManager,repository,docId,targetLocalDirectory));
,我收到第一个参数sessionManger的错误消息,上面写着:“sessionManager 无法解析”。我也尝试在代码中实例化 sessionManager ,IDFsessionManager sessionManager = null;
但它没有解决问题并且错误仍然发生。
任何人都可以帮助我或建议我对以下代码进行更改以纠正此问题吗?
Code1:调用actionevent的导出按钮
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Action Handler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:出口代码:
