[displaytag] problème dans l'export des données

**ghotique** · 23/02/2009, 12h14

Bonjour à tous,

Est ce qu'il y a quelqu'un qui a eu l'occasion d'utiliser displaytag avec Struts2 ?

J'ai des problèmes au niveau de l'export:

Concernant l'export Excel
J'ai 2 problèmes :
1- Quand je fais l'export sous IE ca marche sauf que lorsque j'ouvre mon fichier le système affiche un message m'indiquant qu'il manque des fichiers CSS
2- avec le même code sous Firefox quand je clique sur exporter le système m'affiche la boite de dialogue pour enregistrer le fichier avec une fausse extension du fichier (normalement c'est .xsl or il affiche .action)

Concernant l'export pdf
Quand je clique sur exporter le système m'affiche cette erreur

Code :

http://displaytag.sourceforge.net/1.2/export.html (Text/Binary export views)

Exporting binary data from a JSP is a bit tricky, since JSPs are only designed to output characters: as a starting point keep in mind that binary export is not assured to work on every application server , at least without the help of an external filter (see export filter).

It may work without a filter if your application server allows JSPs to call response.getOutputStream() , but this method really shouldn't be used in JSPs. Using an the export filter, especially in buffered mode, could solve the problem, since the output stream is requested by the filter outside the JSP.

PS: de mémoire j'ai du également augmenter la taille du cache dans mes JSP pour l'export de fichiers de grande taille.

J'ai ajouté ce code

Code :

<%@ page buffer = "1024kb" %>

dans ma page jsp mais ca ne resoud toujours pas mon problème

**karement** · 05/03/2009, 15h57

essaye de préciser le nom du fichier:
export.pdf.filename=test.pdf

et si ça marche toujours pas, peux-tu poster ici le lien sur lequel pointe ton bouton d'export pdf plz.

=> donne le code jsp complet par la même occasion

**ghotique** · 06/03/2009, 11h55

toujours ca génére une erreur
sinon le bouton pointe sur l'url suivant :

Regardes ca : http://displaytag.sourceforge.net/10/export_filter.html

Sinon je vois que tu utilises sitemesh. Peux-être faut-il exclure les download xls de sitemesh ?

J'ai essayé tout ca mais ca ne donne aucun résultat
