How to escape {1} that it appears in the text?
Hi all,
How can I escape curly brackets in my message bundle so that I can
display {1} in my JSP? I already tried with \ or \\ but whenever I don't
receive an error {1} is replaced by 'null' in the text. Hope someone can
help me.
TIA,
Axel

How to iterate forEach in reverse order?
Hi all, I have a forEach loop which iterates from startValue to endValue, which works fine. But forEach wants me that startValue is smaller than endValue. If I want to iterate from a bigger value down to a smaller it's not possible. I tried to switch start and end value but without success. Even to set a step of '-1' didn't help. Is it possible to iterate from a bigger value down to a smaller value? TIA, Axel - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Error loading Applet in IE within Struts application (fixed)
The problem seems to be fixed. The codebase was missing. Firefox and Mozilla didn't care about, but IE. Nevertheless the applet runs if it is executed on the same server but outside the Struts application.

Error loading Applet in IE within Struts application
Hi, this question not typically Struts related, but maybe someone on this list had this error before and can help me. I have an applet which runs well on Firefox and Nescape. Evevn if I put in a single HTML file it is loaded correctly with Internet Explorer. As soon as the applet is integrated in my Struts application it is NOT loaded with Internet Explorer. An IOException HTTP Connection failed occurs. With Firefox and Netscape the applet is loaded correctly inside my Struts application. No problems. As most of the users do use Internet Explorer I can't ignore this problem. All solutions I found so far with google don't match for me (or don't seem to match like problems with upper and lower case charcacters). - IE Version is 6.0.2800 on Windows XP SP1 - JDK / JRE to execute the applet I tried JSDK 1.4.2 [04|05] TIA, Axel - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Uploading files to a database
Ivan Vasquez schrieb:
Hi,
What's the preferred way to upload files into a database in a J2EE Web
application?
Is there any way to stream the file straight from the HttpServletRequest
to the database without staging it in the server's filesystem?
Thank you,
Ivan.
That's how I use it. But in my case I want to store a file on the
server. But it should be easily possible to put the Stream to CLOB or
something like this.
streamIn = file.getInputStream();
streamOut = new FileOutputStream(fileName);
int bytesRead = 0;
byte[] buffer = new byte[8192];
while ((bytesRead = streamIn.read(buffer, 0, 8192)) != -1) {
streamOut.write(buffer, 0, bytesRead);
}
streamOut.close();
streamIn.close();
file.destroy();
file is a FormFile object which you can use with Struts with the
tag.
Cheers,
Axel

Re: errors get lost on redirect
Hubert Rabago schrieb: Well, not really set the input, but you can direct the request to the correct one in your java code. First off, set validate=false on the action. Then, in your action, call the form's validate() yourself. Lastly, if there are validation errors, call saveErrors() to save the error messages then forward the request to the correct input form. Hubert Thank you Hubert, sometimes the best solution is so near and you can't see it. ;-) This works perfectly and was the fastest way to realize this. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: errors get lost on redirect
Bill Siggelkow schrieb: I don't understand exactly why you are doing the redirect? Why not just set the input attribute to be the page you are redirecting to ... then Struts will forward to it when validation fails. Can I set the input attribute in my Java Code? I thought I have to define it in the struts-config.xml. But at design time it's not yet defined to which page the application should forward to. Is it possible to use mapping.setInput(myForward)? That would be too easy. ;-) TIA, Axel - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
errors get lost on redirect
Hi all, in my struts application I have 4 forms which have to be filled to store an item in the database. All 4 forms are inherited from one abstract form class. As form 3 depends on data from 1 I didn't find a better solution, but it works. The problem is the following. When I submit form 4 I can do the complete validation. The ActionErrors are filled correctly, but I return back to Form 4 (of course). I then did a and inside a redirect to page where the error is. The redirect works fine, but the errors get lost on this redirect. Can I somehow preserve my errors when redirecting or can I do this without a redirect. As the ActionClass isn't called I can't call a mapping.findForward() or something like this. I tried to put the errors object in the request scope before doing the redirect but it's not stored - even the session scope didn't work. But that was just a try, I don't want my errors to be in the session scope. I hope someone can enlighten me. :-) Regards, Axel - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: validation for optional fields

hi,
how can I validate an optional field. ie validate only if there is some
value in it. For example. I want to validate a field which should of type
int.But it should be validated only if use has entered some value in it.
hi,
if you are validating in your form or action class you can check if the
field is not empty (!= null or !equals("") and then check for correct
int value.

How to avoid character encoding for html tags
Hi all, I have an application where the user should be allowed to use text formatting tags as or (and so on). To avoid that tags like oder (and so on) are used I check the for these tags before it's stored in the DB. When the text is read from the DB my tags are encoded to . How can this be avoided?

getting a random number with JSTL?
Hi all, I know this is not a JSTL list, but maybe someone can tell me, if there is a possibilty to get a random number with a JSTL tag. Best would be to have min and a max value. If this doesn't exist, I think about wrtiting such a tag for me. But I don't have to do this, if it still exists. ;-) Thanks, Axel - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

We're about to launch a fairly large projetct and I see issues where one developer has validation.xml checked out when another one needs to edit it as a possible problem. //Linus Nikander - If you use CVS it should be no problem to have file which is edited by two persons at one time.

Re: From bean into "for" loop

Hi all,
I am trying to do something as simple as writing a FOR loop with some

bit more cumbersome and difficult than I thought it would be. For some
reason, everything I try seems to fail. Here is a short example of
what I'm trying to do:
<% for(int i = 0; i < ${productData.someCount}; i++) { %>
// Write my text here
<% } %>
What am I missing here? If you could help me I'd appreciate it --
enough time wasted on this thing already.
I think you can solve this with a forEach loop from JSTL. Using EL it
should be quite easy. When I am back home this evening I can send you an
example if you need it.
