Data source

[Daniel WAMARA]

Thanks for the answer but I've forgottent to say that it works fine on my workstation 
(NT4) but I got this on a Linux server.

Unit test the beans outside of Struts.
Just write a System main console app that calls your bean.

Re: Can Dreamweaver and Struts work together

[Daniel WAMARA]

I'm using Dreamweaver since the version 2 and now I'm in the 4th and work 
with Struts, you can use DW4 qith Struts by adding an extension that you can 
find on http://javacentral.compuware.com and download OptimalJ Dreamweaver 
Integration Kit 1.0.9 and you will be able to directly add Struts tag into 
your JSPs but the only problem is the fact that the process takes 2 or 3 
seconds when normal tags take less than a second.

Form values

[Daniel WAMARA]

I would like to make an update of some values of a form and for that, I have to take 
back some values in a database and set the values of the form fields relevant to each. 
I'm trying to use the set Method of the form bean but I got no value back in my form.

Could someone help ?

404 Error - Solved

[Daniel WAMARA]

I've come to yolve the problem : taking a look in the tomcat.log file, I've found that 
there was a ClassNotFoundException relative to the oracle.jdbc.odbc.driver and I've 
just added it to the classpath and now everything is in order.

404 Error

[Daniel WAMARA]

I'm trying to launch a Struts application that is properly working on one of my 
colleague's PC because I have to finish up something but as soon as I try to make a 
login via a login page (which works on other PCs), I have a 404 Page not found error 
and in my Tomcat Console, I have 

"

Someone could give me a hand because I really don't know what to do ? Other Struts 
applications are working well on my PC.

Re: File upload error when no file attached - IOException

[Daniel WAMARA]

Hi Doug, 

I don't know if you've already found solution to your problem but what you can do is 
to put a form validation in your ActionForm that handles that, here is what I did for 
mine (it also handles the case if a file is empty, saying with a 0 Kb size) :

/**
 * Validate the properties that have been set from this HTTP upload request,
 * and return an ActionErrors object that encapsulates a
 * validation error relative to a missing file to be uploaded.  
 * If no errors are found, return 
 * null or an ActionErrors object with no
 * recorded error messages.
 *
 * Creation date: (13.11.01 19:19:10)
 *
 * @param mapping The mapping used to select this instance
 * @param request The servlet request we are processing
 *
 * @return ActionErrors
 */
 public ActionErrors validate(ActionMapping mapping, HttpServletRequest request)
 {
 ActionErrors errors = new ActionErrors();
 FormFile theFile = this.getThefile();   

 if (theFile == null || theFile.getFileName().length() == 0) // as Struts always 
do a temp file for each file you want to upload, "theFile==null" is always false
 errors.add("upload", new ActionError("uploadForm.error.uploadfile.required"));

 if (theFile.getFileSize() == 0)
 errors.add("uploadsize", new 
ActionError("uploadForm.error.filesize.zero.notallowed"));

 return errors;
 }

Hope it helps, 

Daniel

Re: Files download

[Daniel WAMARA 2]

I know none but I made an application doing that, all you have to do is to set up the 
content type of the response. Here's the code I made for :

public ActionForward perform(ActionMapping mapping, ActionForm form, 
HttpServletRequest request, HttpServletResponse response) throws IOException, 
ServletException 
{
HttpSession session = request.getSession();

try 
{
 
String username = getUser(request);
 
String filetoget = request.getParameter("filetoget");
response.setContentType("text/html");
response.setHeader("Content-disposition", "attachment; filename="+ filetoget);
BufferedOutputStream bos = new 
BufferedOutputStream(response.getOutputStream());
FileInputStream fis = new FileInputStream(new File(filetoget));
byte[] buffer = new byte[1024];
int bytes_read;
while((bytes_read = fis.read(buffer)) != -1)
bos.write(buffer, 0, bytes_read);
fis.close();
bos.close(); 

}
catch(Exception me)
{

}

return mapping.findForward("success");
 }

RE: Quickly change page to prevent user to click several times on a link

[Daniel WAMARA]

I think that normally, according to the JSP specification, you can not 
fowrdard them to an html page but only to a JSP so send them to a JSP and 
put the refresh tag in the head, I did it last week and it works.

Can't delete upload temporary file

[Daniel WAMARA]

I've ended up by making a upload module in Struts (thanks to those who 
helped) but now I got a problem with the temporary file struts-created : it 
seems that I can't delete it with the destroy() method.

I've try to create a Security manager to check if I had permission to delete 
the file but the result was that I had none.

try
{
scman.checkDelete(file.getFilePath());
}
catch (SecurityException sexc)
{
...
}

So I created a new Filepermission for being able to set a new permission of 
deletion over the file

try
{
scman.checkDelete(file.getFilePath());
}
catch (SecurityException sexc)
{
...
FilePermission filepermission = new FilePermission(file.getFilePath(), 
"delete");
try
{
...

but I still have that permission and making all the uploads I'm doing just 
for thest could lead to a huge quantity of files, so how could I get ride of 
that ?

Could not locate TLD META-INF/taglib.tld

[Daniel WAMARA]

Hi everybody,

I got this error every time I want to launch a Jsp with some struts tags in

I've try to take a look on the mailing list but the two answers I've found

and 
http://www.mail-archive.com/struts-user@jakarta.apache.org/msg02380.html)

Re: Struts Dreamweaver extension

[Daniel WAMARA]

It works well but is a bit slow when it comes to show properties of a Struts 
tag, I already use Dreamweaver since the version 2 and see the growing of 
that application and working now with Struts, my desire would have been to 
be able to integrate directly Struts tags with DW and now it's done but I 
think that some work should be done about this slow getting of properties.

Iterate tag

[Daniel WAMARA]

I need to use the iterate tag to display elements of 2 arrays but the 
problem is that I don't know if I can really use a nested iteration 
considering the fact that normally, in Java, it should for example be 
handled like this

for (int i=0; i<=list.length-1, i++)
{
  System.out.println(a[i]);
  System.out.println(b[i]);
}

because the value of a[i] and b[i] should be displayed in table cells like


  (the value if A)
  (the value if B)


od should I simply use a scriptlet for that.

Thanks for help.

Re: File upload - Help needed in emergecy

[Daniel WAMARA]

- The form tag's enctype is "multipart/formdata" as it should.
- For the form bean, I just noticed that FormFile was a interface so I 
implemented an "UploadFile" class implementing the FormFile interface (but 
if I did wrong, so just tell me)
- And as you can imagine, the getter and setter return and accept an object 
of type UploadFile.

So what's next so ?

File upload - Help needed in emergecy

[Daniel WAMARA]

Hi each and everyone,

I'm just back from the Servlets.com website and I'm now more lost than I was 
when I entered there :

I'm trying to make a file upload thru a multi-part/formdata and for getting 
the file, I've just implemented a class implenting the Struts FormFile and 
everything should work well I think but as soon as I click on the "Upload" 
button, this is what I get in my page :

Error: 500
Location: /mailorder/upload.do
Internal Servlet Error:

javax.servlet.ServletException: BeanUtils.populate
java.lang.Throwable(java.lang.String)
java.lang.Exception(java.lang.String)
javax.servlet.ServletException(java.lang.String, java.lang.Throwable)
void org.apache.struts.util.RequestUtils.populate(java.lang.Object, 
java.lang.String, java.lang.String, javax.servlet.http.HttpServletRequest)
void 
org.apache.struts.action.ActionServlet.processPopulate(org.apache.struts.action.ActionForm,
 
org.apache.struts.action.ActionMapping, 
javax.servlet.http.HttpServletRequest)
.
.
.
.

Root cause:
java.lang.IllegalArgumentException
java.lang.Throwable()
java.lang.Exception()
java.lang.RuntimeException()
java.lang.IllegalArgumentException()

I will surely not copy paste all the things under this stacktrace.

So someone could tell me what it means and how I should resolve the problem 
(I must give back the upload method before the end of the week), so please 
help.

Struts, JSP, Servlets and dB

[Daniel WAMARA]

Hi,

no good answer has been given to me thru all the websites I went to but I 
should now have to ask my question here I think : I'm brand new in Struts' 
world because I've been hired by a company using it.

Having worked before with servlets where querying databases where a matter 
of SQL statements, I'm not a bit lost : all the examples I've seen were 
using kinda "XML databases" but I now have to make a short application to 
see that I'm a bit good in Struts before beginning my real project next 
week.

I would like to know if I can use some "normal" SQL statements in my Form 
objects extending the ActionForm class ?

Writing the config-struts.xml file, writing the form objects, writing the 
lines of the Actions are not a problem because I now have a good look over 
it but how could I use "normal" databases or tables like I was doing before 
with servlets, like defining the driver, getting the connection, making 
statements and so on...

I was a bit long but it was for a good explanation.

Thanks for helping,

Daniel WAMARA
