Struts for fatclient-server applications
Struts could be used for the server portion of your client-server
application -- the server could be implemented as a standard web
application, perhaps providing XML to the client. The client would play the
role of the web browser -- be the web browser -- in interacting with the
webapplication "server".
Never done it. Duncan notes, Struts is tied to the Servlet API and so a
choice to use Struts for the server portion is really a decision to use a
servlet container contained webapplication as the server portion of your
client-server design.
[[
I've used Struts before for web applications but at the moment I'm
evaluating if it would be possible to use Struts for Java Client-Server
applications (Java fat client). Any thoughts? Has some one seen Struts ever
used in that way?

One approach to evaluate would be using XML-based data exchanges between
your Java client and the server webapp. You can see pointers to several
Struts based extensions in this space at:

You can have multiple forms in a page, but only one
of them can be submitted at a time. Therefore, one
usually provides an with each form
declaration. You can achieve the same with JavaScript,
which you probably do here, but if you say something
document.forms[0].submit();
document.forms[1].submit();
the second line won't be executed anymore, for the
browser has already started a new request.

You can have multiple forms in a page, but only one
of them can be submitted at a time. Therefore, one
usually provides an <html:submit> with each form
declaration. You can achieve the same with JavaScript,
which you probably do here, but if you say something
document.forms[0].submit();
document.forms[1].submit();
the second line won't be executed anymore, for the

Hi,
could well be I'm not fully understanding the exact problem again,
but generally, two in a single JSP page are no
problem. The one you submit ends up in the request, and
gets renderered to just a normal HTML form
tag in the end. On to the beans. I'm not sure what kind of
bean you mean here. If it's the form bean (and it's the same
table), try referring to it in your second via
the token you used for the first one. If we're talking about
two different beans here, you have to make sure both of
them are actually there and bear different token names.
In this case, you have to manually create the 'second'
instance and put it in request or whatever scope so that
it can be found.

Re: html:form
Posted by JavaSoft <ja...@yahoo.com>.
2 forms i assumed you use 2 diffrent actions. It
wouldn't matter how many form you have as long as you
set the action in your struts-config correctly.
If you use 2 forms just imagine you have 2 diffrent
pages, how you deal with it ? so its supposed to be
same as you handle your multiform.

RE: basic problem in java (likely is a CLASSPATH problems on Windows)
Posted by David Friedman <hu...@ix.netcom.com>.
Ancient Chinese Secret (as the 70's/80's commercial goes):
In Windows environments (for me in NT 4.0 and XP Home edition),
you can't use "long" windows pathnames. They must be of the
8.3 variety. Do a "dir /x" in c:\ and see what is listed
for c:\jdk1.3.1. I tried it on mine and it came up
with "C:\JDK13~1.1" as the 8.x path. so your path will probably
have to be fixed to look more like this:
C:\JDK13~1.1;C:\JDK13~1.1\LIB\tools.jar;C:\JDK13~1.1\lib\rt.jar; etc....
Keep in mind the c:\Drivers\classes111.zip might not work because it has a
file name longer than 8.3.
This problem gave me headaches for JDK 1.X.X and Tomcat 4.1 (not for 5.0
since I'd already learned my lesson!).
Check out your paths using "dir /x" and see if fixing your classpath (you
may have to reboot, depending on where/how you set your classpath) to
standard 8.3 directory names works. Again, you might need to do the same for
the .jar files but I don't know for sure since I use Tomcat and Eclipse
making paths 'mostly' unimportant to me.

David
