Hello Venkat,

I don't understand your coding likewise. There is nothing about the SAP GUI for HTML. As I understand it Jaime uses ABAP to download a file via Webgui. No Java, no user specific Javascript as far as I understand the topic.

Hi thzs to all, but my problem was very wierd to say less, i've change the browser to firefox and it work fine. So using IE7 and VISTA generated that problem.

Once again thanks for the time spend to all

Hello Jaime,

> So using IE7 and VISTA ...

Ah. Did you check the settings for the Java VM used in IE?

Hello Jaime,

in R/3 >= 640 there exist a test program istq_upload_download. There you can test the gui_download functionality in general.

Furthermore you can call transaction se24 with class cl_gui_frontend_services and test the method gui_download.

Does this work. Or do you use an older R/3?. What is the error. A java I/O error can be analysed in the java console.

Maybe the file path is not correct.

Best regards,

Ralf

ITSQ_UPLOAD_DOWNLOAD

Hello Jaime,

how exactly looks the error like? Is it a Javascript or a Java error? I am asking because most of the client code of the SAP GUI for HTML is based on Javascript. But for up- and download a Java applet is used.

I remember another questioner in this forum who asked for the Query.class that could not be found ...

With best regards,

Hi TJ,

it's a JAVA I/O error. The strange thong is that the upload is using the same java class and it works fine. Any idea?
