[英]An issue with windward reports using JdbcDatasource
I'm trying to use Windward reports for making a simple report. 我正在尝试使用Windward报告制作简单报告。 I use JdbcDataSorce object in order to connect Oracle database.
我使用JdbcDataSorce对象来连接Oracle数据库。 Here's the code:
这是代码:
package org.qrf.test;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;

import net.windward.xmlreport.SetupException;
public class SQLDatasourcePrintTask {
public static void main(String[] args) {
Connection conn = null;
try {
Class.forName ("oracle.jdbc.OracleDriver");
conn = DriverManager.getConnection(
"jdbc:oracle:thin:@//localhost:1521/mybase", "scott", "tiger");
JdbcDataSource ds = new JdbcDataSource(conn);
ProcessReport.init();
// объявление полей таблицы шаблона
ArrayList<JdbcDatasetField> fields = new ArrayList<JdbcDatasetField>();
fields.add(new JdbcDatasetField("SNAME_EDI", "VARCHAR2", "SNAME_EDI", null, DatasetField.TYPE_COLUMN));
fields.add(new JdbcDatasetField("NAME_EDI", "VARCHAR2", "NAME_EDI", null, DatasetField.TYPE_COLUMN));
fields.add(new JdbcDatasetField("ID_EDI", "NUMBER", "ID_EDI", null, DatasetField.TYPE_COLUMN));
fields.add(new JdbcDatasetField("CODE_EDI", "NUMBER", "CODE_EDI", null, DatasetField.TYPE_COLUMN));
// объявление набора данных
JdbcDataset dataset = new JdbcDataset("SPR_EDI_DATASET",
"select se.id_edi, se.name_edi, se.sname_edi, se.code_edi " +
" from SPR_EDI se", "---", fields);
// Объявление потоков
InputStream in = new FileInputStream(new File("template/sql_template.rtf"));
OutputStream out = new FileOutputStream(new File("sql_datasource_out.rtf"));
// объявление RTF-процессора
ProcessRtfAPI process = new ProcessRtf(
in, out);
process.processSetup();
// объявление карты переменных
HashMap<String, Object> variablesMap = new HashMap<String, Object>();
variablesMap.put("id_edi", 100);
ds.setDatasets(new Object[]{dataset});
ds.setMap(variablesMap);
process.processData(ds, "SPR_EDI_DATASET");
process.processComplete();
out.flush();
in.close();
out.close();
} catch (ClassNotFoundException e) {
e.printStackTrace();
} catch (SQLException e) {
e.printStackTrace();
} catch (DataConnectionException e) {
e.printStackTrace();
} catch (LicenseException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (SetupException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (TagException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (AlreadyProcessedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (DataSourceException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (BeanProviderException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (TemplateParseException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (OutputLimitationException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} finally {
try {
conn.close();
} catch (SQLException e) {
e.printStackTrace();
}
}
}
} }
I also use simple template created with an AutoTag tool 我还使用通过自动标记工具创建的简单模板
When I run this program it seems that connect to database is successful, but when I open the output file after finishing I get the same contents as in the picture above. 当我运行该程序时,似乎连接数据库成功,但是在完成后打开输出文件时,得到的内容与上图相同。 Please help me to solve this problem.
请帮我解决这个问题。
Generally when this happens the problem is your call: 通常,发生这种情况时,问题出在您的电话上:
process.processData(ds, "SPR_EDI_DATASET"); process.processData(ds,“ SPR_EDI_DATASET”);
uses the name "SPR_EDI_DATASET" but the tags in the template have a different name for the datasource. 使用名称“ SPR_EDI_DATASET”,但是模板中的标记的数据源名称不同。
