How to convert struts FormFile to oracle blob Object?
Hi, I use <html file> upload a file in FormFile format, anyone has any
idea about how to set the file into the oracle database as a Blob object
using JDBC?
Thank you very much.

Thanks for you help Craig. I think the <meta> tag looks the cleanest way and
I'll use that.
Regards
Jim.

I suppose one could do that, and even stick it (the response object)
into the request attributes to make it visible to the EL via the
"requestScope" magic variable. But a property setter only takes a
single argument (the value), so you'd need a property setter for every
possible header (which is technically infeasible, since the set of
possible headers is unbounded), and you still wouldn't be able to deal
with the cases where more than one value for a header can be added (via
response.addHeader()).
It is a far far better thing :-) to just use the <meta> tag that HTML
provides for exactly this sort of purpose.
<meta http-equiv="Header-Name" content="${the.value.for.this.header}">
Besides the performance advantages of skipping all the mapping and
facading, and making people scratch their heads over the resulting EL
expressions, this has the advantage of clearly describing what's going
on to anyone who is familiar with HTML.

Unfortunately the "response" implicit object (that the JSP page compiler
provides) is not visible through the EL directly. Even if it were,
however, it wouldn't help much because you can only call property
getters with EL expressions; not arbitrary methods with arbitrary
parameters.

Re: Slightly OT How to set a request header using JSTL
Posted by Jim Collins <ja...@blueyonder.co.uk>.
Hi Craig,
Thanks for your response. I wanted to set the header in the JSP page itself.
At the moment I set the header using a scriptlet (as you described in your
post) but I would like to disable scriptlets in my JSP pages.
I was playing around with the EL and could print out the headers using this
but I could find no way to set a header. I believe that Struts provide a tag
that encapsulates the response that I could manipulate using the EL but I
was wondering if I could do it using the explicit response object in the EL.
Regards
Jim.

Re: Slightly OT How to set a request header using JSTL

The "header" object relates to the *request* headers. You can set
*response* headers in a number of ways:
* (Servlet 2.3 or later) in a Filter that wraps and postprocesses
the response
* In your Action (although that only works if you also do the output
itself; doing a request dispatcher forward will clear the headers).
* In a JSP page with scriptlets (as long as it's before the response
is committed):
<%
response.setHeader("Foo", "bar");
%>
* In a JSP page with HTML <meta> tags in the <head> section:
<meta http-equiv="Foo" content="bar">
* (JSP 2.0 or later) you can use EL expressions to get the value part
of the header from a bean property dynamically:
<meta http-equiv="Foo" content="${mybean.fooValue}">
* Ugly but workable using a Struts tag get the dynamic value:
<meta http-equiv="Foo"
content='<bean:write name="mybean" property="fooValue"/>'>
This only works because <meta> is not a custom tag; otherwise
the nesting syntax would be illegal.

Slightly OT How to set a request header using JSTL
Posted by Jim Collins <ja...@blueyonder.co.uk>.
Hi,
I know how I can read request headers using c:out and the header object.
Does anyone know how I can set a response header using c:set? Can it be done
without using the response tag? I don't want to use scriptlets.
Thanks
Jim.

Re: How to convert struts FormFile to oracle blob Object?
Posted by Bill Siggelkow <bi...@bellsouth.net>.
Basically, from the FormFile you can get an input Stream for reading --
the hardpart is writing to the Oracle Blob -- here are some links that
should help:
