Ajax を使用してアクション クラスによって生成された PDF ファイルをダウンロードして開くにはどうすればよいですか?

<code class="java">public String execute() {
    ...
    ...
    File report = signedPdfExporter.generateReport(xyzData, props);

    inputStream = new FileInputStream(report);
    contentDisposition = "attachment=\"" + report.getName() + "\"";
    contentType = "application/pdf";
    return SUCCESS;
}</code>

<code class="javascript">$.ajax({
    type: "POST",
    url: url,
    data: wireIdList,
    cache: false,
    success: function(data) {
        // Convert the response data to a Blob object
        var blob = new Blob([data]);
        // Create a link element to trigger the download
        var link = document.createElement('a');
        link.href = window.URL.createObjectURL(blob);
        // Set the desired file name for download
        link.download = "filename_with_extension.pdf";
        // Simulate a click event to initiate the download
        link.click();
        // Remove the Blob URL once the download completes
        window.URL.revokeObjectURL(blob);
    },
    error: function (XMLHttpRequest, textStatus, errorThrown) {
        alert('Error occurred while opening fax template' + getAjaxErrorString(textStatus, errorThrown));
    }
});</code>
