Re: File Upload DEPRECATED?
Posted by Martin Cooper <mf...@gmail.com>.
The package is *not* deprecated. What is deprecated is the old, buggy
implementation. The replacement is not Commons FileUpload, but is a
Struts wrapper around Commons FileUpload. See
CommonsMultipartRequestHandler. That implementation has been the
default implementation in Struts for quite some time now.
As for an example, there is an example in the Struts distribution
itself. Look for the 'upload' example within the 'struts-examples' web
app.

File Upload DEPRECATED?
Posted by Ivan <iv...@interd4u.com>.
I don t understand. As you see here
(http://struts.apache.org/api/org/apache/struts/upload/package-
frame.html) This package is almost deprecated in favor of commons-
fileupload.
Ok i have remove the method based on struts 1.1 example(example and code
that is remove on struts 1.2.2!!!), and i test that commons-
fileupload... and several hours wasted i have found that it don t wanna
work with struts.
Have you tested commons-upload with struts? Where is the example of
using commons-upload with struts the same way it was an example using
struts-self-thing.
It is REALLY a pain to code deprecated code without having access to the
code that will replace the deprecated code (do you know ? the
@deprecated use XXX class instead of, that you don t write on source).

Don't you remember she was worked in the bathrooms at one of the hotels.
And George wanted to use her for something I forget what now. I think to
eavesdrop on someone while they were in the bathroom. I think Newman

Sounds right, but I don't think I ever saw her on the show.
Babu was Jerry's Pakistani friend/neighbor who owned a local restaurant
that served American food. Jerry went in and convinced him to serve
authentic Pakistani food. Babu immediately lost all his customers and
went out of business. Later he lost his green card (thanks to another
fiasco involving Jerry and Newman) and was deported.
He later resurfaced to help seal Jerry's fate (a prison term) during the
"good samaritan" trial.

Sounds to me like you are trying to do a file upload, with a few extras
(such as letting the user delete and rename existing files).
There are a couple areas of complication here, but nothing you can't
handle if you are willing to do your homework. Start with the Struts
file upload example which comes with the 1.1 distribution. Look at the
JSP (the form) and the source code for the form bean and the action.
FormFile is the key. Once you get a simple file upload working, the rest
is just Java IO and JDBC programming.
Next, you'll need to design a database to hold your file metadata, and
allocate a directory on the server box where you can begin a storage
tree for uploaded files. I suggest keeping all files on the filesystem
and keeping all information about the files in the database. There is
the possibility of keeping the file data in the database as well, but I
wouldn't consider doing that until you know you have a good reason,
unless the files are very small.
I would suggest scratching out some possible method signatures such as
renameFile(String oldName, String newName),
renameFileByPrimaryKey(String pk, String newName),
deleteFileByPrimaryKey(String pk), etc., so you'll know ahead of time
what you've got to implement.
Since you also have more than one submit button, you'll need to do a
little research on multiple submit buttons with Struts (and in general).
There have been many threads on this topic in this list, so search the
archives (www.mail-archive.com, etc.).
Hope that helps,
Erik

Okay -- what you need to do is first stand on one foot ... now with your
nose and your right index finger press Ctrl-Alt-F7.
Then spin around three times while singing "I am a little teapot ..."
This should solve your problem -- if it doesn't maybe you can provide

I agree as well, but just wanted to point out one additional detail
... if you override the equals() method, you will probably also want
to override the hashCode() method as well, because the semantics of
the two are linked. Normally this can be done by calculating the hash
for the bean itself based on the hashCode() value of all the
properties -- the important thing is that if equals() returns true,
the hashCode values should be equal.
See the javadocs for java.lang.Object for more details.

Erik's answer is what I would call the correct one... That being said, if
for some reason you don't want to use that approach, I don't think there's
anything specifically in Struts to do what you want anyway, but you might
want to have a look through the Commons BeanUtils packages. If such a
thing exists, I'd bet on it being there.

Re: COMPARING PROPERTY VALUES OF TWO JAVABEANS ...please help
Posted by Erik Weber <er...@mindspring.com>.
Why don't you just override the equals method in your bean class?
public boolean equals(Object o) {
if (!(o instanceof MyClass)) return false;
MyClass bean = (MyClass) o;
if (!(name.equals(bean.name))) return false;
if (!(sex.equals(bean.sex))) return false;
//etc. . .
return true;
}
Then you can just ask:
if (bean1.equals(bean2))

COMPARING PROPERTY VALUES OF TWO JAVABEANS ...please help
Posted by "O. Oke" <re...@yahoo.co.uk>.
Please, I want find out if the value of each of the
matching properties in two beans are the same.
BACKGROUND
==========
I have two JAVABEANS A AND B. They both have name and
sex properties amongst others. I want to find out if
A.name == B.name and A.sex == B.sex.
Is there any method in Struts that is designed to do
this type of comparison? i.e.
int objName.compareJavaBeans(javaBean1, javaBean2)
Presently, I am doing this:
String beanBk = customerBeanBk.getCustomerNo()+
customerBeanBk.getFirstName() +
customerBeanBk.getLastName();
...
String beanDbCp = customerBeanDbCp.getCustomerNo() +
customerBeanDbCp.getFirstName() +
customerBeanDbCp.getLastName();
...
if (beanBk.equals(beanDbCp)){ ..... }
Thank you
