Grails 2.0.4 を使用してアプリを作成し、Jetty でテストしました。Jetty ではすべて正常に動作しますが、Glassfish にデプロイすると、アクションでファイルを割り当てようとすると npe が発生します。グラスフィッシュでは UploadFile が null になるのに、jetty では問題ないのはなぜですか?

def  uploadedFile = request.getFile('name_of_file')

Firebug は、http 要求がファイルを取得していることを示しています。Firebug からのマルチパート フォーム データ Post リクエストの冒頭は次のとおりです。

**name_of_file**    %PDF-1.4 %âãÏÓ 5 0 obj <</Length 2712/Filter/FlateDecode>>stream x[]oÜ6}_A /ÛÝZD}öM+¶ñÌT#'5¶ÂuÄeolÅþüÔ¥D^êòÑ(PÏuyι<¤4²úuuÚ¬|æ!k>®ÊfõëêëÊ÷|ÆìïUÈ~ÿñ

したがって、展開時にファイル情報がクライアント側でパラメーター化されているように見えますが、コントローラーには作成されていません。

私のコントローラーコード:

 def sample(){

    if (params.ID == null) return 

    def sampleInstance = new Sample(params)// new sample
    if (sampleInstance.validate()) { // try to validate
        def  uploadedFile = request.getFile('name_of_file')// see if there is a file to upload
        session.uploadedFile = [
            originalFile: uploadedFile.originalFilename
        ]



        if (uploadedFile != null) { // is there a file? 
            sampleInstance.filepath =${uploadedFile.originalFilename}" // save the original filename

        }
        if (params.ageUnk){
           sampleInstance.sampleAge = null;
        }
        if (!params.ageUnk){
        def patients_age_in_years = (Integer.parseInt(params.patientYrs) * 12)

        def patients_age_in_months = Integer.parseInt(params.patientMos)

        def patients_total_age_in_months = (patients_age_in_years + patients_age_in_months) 

        sampleInstance.sampleAge = patients_total_age_in_months
        }

        sampleInstance.enteredby = springSecurityService.currentUser.id 
        sampleInstance.save()// save the sample in the database

        redirect( action:'sample', model:[sampleInstance:sampleInstance, checkDate:today, date: now])

    }else{
         [sampleInstance:sampleInstance, checkDate:today, date: now]
    }

}

ファイル以外のすべてのパラメータが通過できます。ここに私のgspフォームがあります: 

<g:uploadForm action="sample">
<table>
  <tr>
    <td align="right"><br><b> Comments: &nbsp</b></td>
    <td><br><g:textField name="nameComments" value="" style='width: 200px'/></td>
  </tr>
    <td align="right"><br><b>ID: &nbsp</b></td>
    <td><br><g:textField name="nameID" value="" /></td>
  </tr>
  <tr>
    <td align="right"><br><b>Upload File: &nbsp</b></td>
    <td><br><input type='file' name='name_of_file' /></td>
  </tr>
  <tr>
    <td align="right"></td>
    <td><g:submitButton name="submit" value="Submit" /></td>
  </tr>
</table> 

</g:uploadForm>

どうやらこれは Glassfish 3.1.2 の問題です。今朝、自分の問題に関するツイートを見つけて、このJIRAにたどり着きました

web-core.jar ファイルを置き換えると、問題が解決しました。概念実証のために、Glassfish 3.1.1 をダウンロードし、そのバージョンで問題なくアプリを実行しました。したがって、すべてが 3.1.2 が私の問題の根本原因であることを示しています。私のアプリには何もありません。
