Wierd Message Format

Re: Test for an empty string

23-Jun-05 5:35

Ok..just wondering if anyone else has run into this problem. At work we are building return url's to send to different apps. For this we use MessageFormat.format. for example

l_url = MessageFormat.format(<br />
	l_url,<br />
	new Object[] {<br />
	"fooProcessing?foo=true",<br />
        getUrlInfo(),<br />
	getDeployment(),<br />
        l_userId,<br />
	l_returnJsp});

In this example, l_userId is of the object type Integer. Now, lets say for a moment that my userId is 1011. Now when I call the toString() function I get returned "1011". The MessageFormat.format however is somehow formatting l_userId to be "1,011." Which as you guessed, totally blew up our return urls, as when we go to convert that userId to an Integer, it doesn't like the commas. My question is, why did it do this? Shouldn't this just call a simple toString() implicitly as we are inserting them into a string? Another question I have is, if Integer can format that way (with the comma) why can't it take a number with commas in it when creating a new Integer?

Test for an empty string

Hey,
Well I figure I would post a question here becuase well I need an answer and no one ever posts here! I am sure this is a simple question but here goes. I am using the method startsWith that is a part of the String class and in the api it says that this will return true if an empty string is passed to the method. This is diffently not ok for what I am doing so I was wondering I would test for an empty string? Do I just do stringName.equals("") == true? Is there a solid way for me to test for this? Thanks for all of your help...well those that check this board!

Wow, and actual post!!! I always do

if( !stringName == null || !stringName.equals("") ){

}

when testing for empty strings.

Maybe Chris couldn't get a sponsor deal with Microsoft if he didn't close down the board? Unsure | :~

What puzzles me, is that there is still a Java Article Forum.

Hey,
I have a module that I have built that has uses swing. It has a table, an input panel and a bunch of buttons to do a few different tasks. The table is populated from the database and when the user enters his input vaules a column in the table gets populated. Now I have a button the user presses to print a report, a button the user presses to email his report and a user asked me to have a button that would just launch the email with the data dumped into the body of the email. So I have extracted the data and stored it into a StringBuffer. I have the data formated with tabs and returns. Now I am not sure how to lauch the default mail client. I tried doing it like so but it did not work because 1 my data was larger than 1K and 2 it does not support my tabs and returns:

cmd /c start \"\" \"mailto:?subject=test&body=" + body + "\""

Is there any way I can launch the default mail program and have my data dumped into the body of the email?

Thanks for all of your help! I have spent 2 days trying to figure this out and its driving me nutts! Frown | :(

An applet can open the mail application like that:
getAppletContext().showDocument("mailto:me@me.net?subject=test&body=text");

An application should be able to do the same by writing the email and the SMTP headers into a .eml-file and then launching the file with the default application:
cmd /c start tmpFileName.eml

How do I create the eml file? Is this easy to create?

Corinna John19-Apr-05 10:20

19-Apr-05 10:20

Launch your default mail application, and save a mail to a file. The result is an eml file. It contains headers and text, and can be read by other mail applications.
For example, this is the eml file of a CP notification mail:

I copied the above and put them in a file called test.eml and it launched outlook express. I am currently using Microsoft Outlook so it has to open in regular Outlook. Is this still possible?

Thanks for all of your help!! Big Grin | :-D

I guess the .eml files are associated to the default mail client, so it should be ok.

My default mail client is Microsoft Outlook and the eml file that is opening in Outlook Express. I think the eml file may be an Outlook Express file. I have been trying to save the file as a .msg, .oft or .rtf file but they are not opening in Outlook. I am not sure of the format. I hope there is a nother option Sigh | :sigh:

Does creating a MimeMessage make this any easier?

Wow, a secret forum!

Is this the hiding place for insiders, or a piece of history in the CP database?

I guess you got an invitation, hmm?...
This is where Java programmers tries to come out of the closet without getting stressed by prejudiced C++ programmers.
We even got a secret handshake, it involves the notorious Java Ring, but more about that later. You'll soon learn about it all in the secret introduction ceremony.

It's good to know that I'm not alone in the universe of people who like Java _and_ .NET.
