one good way is to create a custom resource in your application's
constructor.
it's very easy to do this way. if you're using my contrib-database
stuff, you even
get blob support for free via DatabaseResourceStream... see code below
jon
----
getSharedResources().add("myResource", new Resource()
{
public boolean isCacheable()
{
return false;
}
public IResourceStream getResourceStream()
{
try
{
long id = getParameters().getLong("id");
X x = (X)getDatabaseSession().load(X.class, id);
return new DatabaseResourceStream(x.getBlob())
{
public String getContentType()
{
return "application/whatever";
}
public Time lastModifiedTime()
{
return Time.now();
}
};
}
catch (StringValueConversionException e)
{
throw new RuntimeException(e);
}
}
});

Hi Juergen,
Thanks for your response. I'm still a bit cunfused as to what the appropriate
pattern is for overall binary file transfer.
I tried streaming data out from configureResponse(), tried not calling
super.configureResponse(), etc. but I still cannot get the formula right. Do I
need to redirect to another page (different from the onClick() handler page)?
Should I stream data from onBeginRequest() instead?
Does anyone have an example of this?
Thanks.
