Hej
Er der en der kan se hvorfor denne her ikke virker i explore men fungere
fint i netscape.
når den kører i en explorer, kommer der ingenting op og efter en 2 minuters
tid kommer den med en io fejl.

Nu har jeg brugt en uges tid på det, og er fuldstændig løbet tør for ide'er
så det ville virkeligt værer fedt hvis der er en der har løsningen.

Med Venlig Hilsen
Claus

Når din servlet at levere sit output før balladen opstår?
Hvor langt når den?

Hvor lang tid tager det med netscape? Kan det være IE der timer
ud, og derfor lukker forbindelsen (hvilket giver en IOException)?
Må vi se de første par linier af din exception?

Prøv evt. at sende Content-Type og Content-Disposition headers.

response.setContentType("application/pdf");
response.setHeader("Content-disposition","inline;filename=\"boo.pdf\"");
