Holger,
This is what I did, perhaps it'll give you some hints on how to fix your
problem:
SomePage.html
...
<input type="button" value="Download PDF Report" onClick="serviceLink()"/>
...
<script type="text/javascript">
function serviceLink() {
window.location='<span jwcid="@Insert" value="ognl:serviceURL"
raw="true"/>';
</script>
...
SomePage.java:
...
@InjectObject("engine-service:download")
public abstract IEngineService getDownloadService();
public String getServiceURL()
{
ILink link = this.getDownloadService().getLink(false, new
String[]{...User Report Params...});
return link.getAbsoluteURL();
}
...
I believe other code you can gather from Kent's book...
hth,
Dennis

Only partially! But actually I don´t know what the real problem is, so I
thought that maybe in your code I could figure out.
We have the following issue (using tap 4.0.2 with tacos):
I have form which is submit by a @Submit. In the form the user can edit
parameters that are needed for report creation.
The @Submit as a action binding which is calling a listener method. In this
listener method we want to generate a report with the parameters defined in the
form. Therefore we are using an custom IEngineService that returns the PDF to
the browser.
Everything works fine but after the report has been created and has been sent to the
browser as PDF, a Exception is thrown saying that getOutputStream() has already been
called. We have read the section "Downloading ..." in Kents book, but at the
moment we have no idea where to go to stop this exception.

Shing's code didn't show you what you needed?

Let me know if Shing's example (it looks to be pretty good) isn't enough for you. The code I wrote
was for a client, but there's really not much "clientness" to it, so I could probably
share it. All it does is take image data out of a blob in the database and stream it back. Not
rocket science by any means. The hardest part of it is the "servicey" bits.
p.s. For the record, that's two phrases that I coined in the same
email :-)

Have some code to share? I'm sure we'd all love to see it.
