我的按钮点击事件代码是这样的:
private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {
try {
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
Connection con = DriverManager.getConnection("jdbc:odbc:Sample");
HashMap hm=new HashMap();
JasperReport jre;
jre=JasperCompileManager.compileReport("D:\\test java\\JavaApplication2\\report2.jasper");
JasperPrint jr = JasperFillManager.fillReport(jre, hm, con);
JasperExportManager.exportReportToHtmlFile(jr, "D:\\test java\\JavaApplication2\\report2.html" );
JasperViewer.viewReport(jr,false);
} catch (ClassNotFoundException ex) {
System.out.println(ex.getMessage());
}
catch(SQLException se)
{
System.out.println(se.getMessage());
}
catch (JRException ex) {
System.out.println(ex.getMessage());
}
}
netbeans 中的异常

最佳答案
您可能缺少 jasper 报告依赖项。
似乎您没有将 apache commons-digester.jar 添加到类路径中。
您还需要: commons-beanutils 公共(public) Collection 公共(public)日志记录
关于java - jasper 在 netbeans 中工作正常，但抛出异常，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/5839077/
