我收到了標題中提到的錯誤消息。我嘗試了在不同論壇中發現的所有內容，但都沒有成功。從bean中檢索字段值時出錯：JasperReports中的名稱
這是我Bean類：
public class NameBean {
private String reportName, shortDescription, description;
public NameBean(String reportName, String shortDescription, String description) {
this.reportName = reportName;
this.shortDescription = shortDescription;
this.description = description;
}
public String getName(){
return reportName;
}
public String getShortDescription() {
return shortDescription;
}
public String getDescription() {
return description;
}
public void setName(String reportName){
this.reportName = reportName;
}
public void setShortDescription(String shortDescription) {
this.shortDescription = shortDescription;
}
public void setDescription(String description) {
this.description = description;
}
}
這是工廠類：
public class TestFactory {
public static ArrayList generateCollection() {
ArrayList collection = new ArrayList();
collection.add(new NameBean("PS_TF_VSGM-A-2535_01", "Automatisches Starten der Online-Prüfung und -Aktualisierung",
"Der Konfigurationsparameter zur Online-Prüfung und -Aktualisierung(MODE_ONLINE_CHECK) ist auf den Wert First konfiguriert. Es wird eine eGK in das Kartenterminal des Konnektorsimulators gesteckt für die im laufenden Quartalnoch keine Online-Prüfung durchgeführt wurde."));
collection.add(new EntranceValuesBean("eingeschaltet", "online", "Ohne TLS", "Standard (PTV 1.6.0)", "Mandat > Terminal > Karte"));
return collection;
}
}
這是我的XML

我絕對不知道如何解決這個問題。
什麼是'EntranceValuesBean'？你是怎麼用這門課的？您應該將傳遞數據源的代碼發佈到報表中 –
