[更新]ボタンをクリックすると、jsp（更新用）のポップアップが開きます。また私はmain.jspからupdate.jspに良いid（Urunler id）を送っています。しかし、いつもポップアップJSPにはIDが後ろから来ています。たとえば、私はmain.jspの1.idをクリックし、?id=1としてokを返しますが、ポップアップJSPはnull（formatExceptionを送信）です。もう一度クリックすると、2. idをクリックすると、ポップアップJSPが?id=1と表示されます。だから、イドはいつも背中から来る。 main.jspでポップアップjsp java.lang.NumberFormatException：null
マイクリックコード：main.jspで
<td>
<a onclick='popup()' href="managergosterim.jsp?id=<%=user.getUrunId()%>" >Güncelle</a>
</td>
ポップアップJSPものは：
function popup(){
window.open('update.jsp?<%=request.getQueryString()%>','name','width=500,height=500');
}
これが私のmain.jspある
