私のJavaクラスのコードは...私が欲しいのは、Excelのレポートを生成することです..どのようにtransformer.transformXLS(templateFileName、beans、destFileName)メソッドのパスを与えるか教えてください..私はコピーする必要があります私のWebプロジェクトのどこかのファイルをExcel?
私はuser ::からtakeinput.jspを使用して入力を取得していますが、idの値はReportServletに、次にReportGenに移動します。データベースから値を取得するためのjdbcコードを記述しています。エクセルシートを作成する。助けてください ??
takeinput.jsp
<body>
<form id="reportformid" name="reportform" action="ReportServlet" method="get">
Enter the ID of the person :: <input id="idid" type="text" name="id"/><br><br><br>
<button id="button" name="reportbutton" type="submit"></button>
</form>
