Re: Problems serving PDF to Netscape browsers

My ultimate goal is to server dynamically generated PDF documents generated with iText. I've got it working just fine with MSIE. However, I was just getting blank pages with Netscape (and it wasn't even showing the toolbar for Acrobat). With NS6 I could at least see that it started an AcroRd32.exe process, but NS4 didn't even get that far. So, I did some tests to rule out some variables. I grabbed a handful of pre-generated PDF files and stuck them on my Apache 1.3.23 server. All browsers could display the PDFs just fine. Then I set up Tomcat 4.0.3 to server the same files directly without going through Apache. MSIE worked, but both NS browsers gave a blank page with no Acrobat plugin toolbar. Again NS6 managed to start an Acrobat process, NS4 didn't. My production environment is Apache 1.3.23 and Tomcat 4.0.3 connected with mod_jk. -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED] -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED] -- NOTICE: The information contained in this electronic mail transmission is intended by Convergys Corporation for the use of the named individual or entity to which it is directed and may contain information that is privileged or otherwise confidential.

What is the value of auto-assigning beans?
This question may be asked out of ignorance, but it seems to me that using the tag: jsp:useBean id=MyBean scope=session class=Test.MyBean / jsp:setProperty name=MyBean property=* / to assign values from form fields to the bean is of limited use. Let's assume that there are 2 text fields, A and B on Jsp1.jsp, with B being required. I have some code that checks to make sure B is populated, if it's not, the browser returns to Jsp1.jsp. The problem I run into is that I can populate A with a value, submit the form, get returned to Jsp1.jsp, delete A and populate B, submit the form, and continue. I how have values for both A and B, even though A was blank. I suspect that I'm not the first person to ask this question, is there an obvious solution that I missed, if not, what do other people do to get around this problem; do all of the assignements by hand?

RE: What is the value of auto-assigning beans?
Yes, I considered that, but I need the values to persist. The only data in the bean that needs to change in the bean is the data that corresponds to the form fields. Perhaps the answer is to have several beans that expire every request, but if you need to persist the data, you still end up copying all of the elements from one spot to another. So I'm still left with the question of Is auto-assigning worth the trouble.

Was there an answer to this? (setProperty and repeating form fields)
I find myself in a situation similar to this, and I wondered if there was
ever an answer to the question.
In order to set my bean properties based on an incoming (POST'ed) HTML
form,
I'm using the following construct in a JSP page:
jsp:useBean id=ord class=ord.OrderBean scope=request
jsp:setProperty name=ord property=*/
/jsp:useBean
It works fine except now I want to process something a little different.
I'm
working on an Order entry system and the Order Items are a repeating group
of
fields. In my HTML form I have input fields named like partNumber0,
quantity0, price0 and partNumber1, quantity1, price1 that repeat for
each
potential item in an order.
Is there any way to use the jsp:setProperty construct to automatically
set
the properties in an OrderItems bean. I'm guessing it might have something
to
do with indexed properties but I really can't see how this would work. If
I
have my bean as
public class OrderItemBean
{
String[] partNumber;
...
public void setPartNumber( int index, String value ) {...}
...
}
Is the JSP runtime going to be able to take the partNumber0 field and be
able
to call my indexed-property setter method with the correct index. What if
I
use the version
public void setPartNumber( String[] value );
as my setter method?

Re: Tomcat install on Cobalt.
I've never installed tomcat on a cobalt server, but I'll take a crack at your question. You need to have the JAVA_HOME environment variable pointed to the place you installed the jdk. So if your jdk is in /usr/local/jdk1.3, then your JAVA_HOME variable would equal /usr/local/jdk1.3. And the part about the path is just saying make sure that the interpreter is in your path. If you can go to a command prompt and type java -version, or something like that, you should be fine.

How to get the working directory?
Apologies if this is off topic, but I was able to rationalize the post. How do you get the working directory of a jsp or servlet -- short of hard-coding the path? The system property seems to point to where tomcat was started, which makes a great deal of sense, but I'm not sure what other approach to take to get the path of the jsp?

Question about Buffering
I have a simple jsp that turns off buffering, and writes to the output stream,
then loops for 30 seconds and writes again to the output stream (source at the
bottom).
My expectation was that, since there was no buffering that as I wrote to the
stream, the result would print to the browser as the script ran, then 30 seconds
later the rest of the text would print. Obviously this is a misconception, the
jsp executes and when it is complete it sends everything.
My question about the buffer is this, what if the buffer is filled, but the
script is still processing? Is a second buffer filled or 3rd, etc. until the
processing is completed and then all buffers get combined and sent in the
stream? Thanks, and apolgoies if the question is overly-simplistic.
Thanks.
