i have added a delete button on the table that i have created to allow user to delete values straight from the table and the database will then be updated. however when i try to run the program an error incurred.
Error: java.lang.IllegalArgumentException: unrecognized virtual form name: addIncidentStatus
my code as follows:
public String Del_btn_action() {
form1.discardSubmittedValues("addIncidentStatus");
try {
RowKey rk = tableRowGroup1.getRowKey();
if (rk != null) {
incidentStatusDataProvider.removeRow(rk);
incidentStatusDataProvider.commitChanges();
incidentStatusDataProvider.refresh();}
} catch (Exception ex) {
log("ErrorDescription", ex);
error(ex.getMessage());
}
return null;
}
By the way the "addIncidentStatus" is a function in the sessionbean.
May i know what went wrong?

Hello i have no idea if i should post it at the java forum pr the database forum, pardon me if i post it at the wrong forum. i am currently using netbeans, javadb and glassfish for my project and right now i created a table that allow user to insert values into the database.
The table contains of 2 attributes a ID and Name.
Problem : http://img827.imageshack.us/img827/673/helpnb.png[^][^]
when the user try to add a 24 again as the ID an error page will popup. how do i create a message instead of the error popup?

Catch the exception[^] and deal with it.
Just say 'NO' to evaluated arguments for diadic functions! Ash

You need to handle the exception and then display your customize message box as your requirement.
take a look there[^] for getting more details about Exception.

i have this particular line in my program however when i execute this line it gives me error.
Integer addIncidentID = (Integer) getIncidentidtxt().getValue();
how do i convert from string to integer?
|
|

Of course you can't cast a String to an Integer, they are two completely unrelated types. You have to use the Integer.valueOff(String s) method:
Integer addIncidentID = Integer.valueOff(getIncidentidtxt().getValue());
|
|
|
|
|
// to primitive int i from Integer Object ii
int i = ii.intValue();
// to Integer ii from primitive int i
Integer ii = new Integer( i );
|
|

this is a static method of the type Integer:
int iValue = Integer.parseInt(givenString);
This one throws an exception when converting fails. So best is to wrap in a try/catch:
int iValue=0;
try{
iValue = Integer.parseInt(givenString);
}
catch(NumberFormatException oException){
}

can i use interger.parseint?
|
|
|
|
|
that's kind of the one I mentioned - if "interger" is just a typo and is supposed to be "Integer".
see post above your post.

Please, check the javadoc !
Yes you can use parseInt but it returns an int, not an Integer. So, depending on your needs, either use valueOf or parseInt.

you can convert string to integer by using various ways
you can use valueOf method of Integer class in this way
Integer obj = Integer.valueOf(str_value);
you can use Integer Constructor
Integer obj = new Integer(str_value);
you can use parseInt method
int objt = Integer.parseInt(str_value);
for more details move there[^]

For Example:
String abc123 = "123";
Integer abcint = Integer.valueOf(abc123);
|
|
|
|
|
|
int int_page_id=o;
String str_page_id="5";
try {
int_page_id = Integer.parseInt(str_page_id);
} catch(NumberFormatException ex) {
ex.printStackTrace();
}
|

|
|
|
String a="2";
int value = Integer.parseInt(a);

Hey!
I need to save some properties encrypted. So I have a key and a value, which I should separate in some way with some character or symbol. The most used "=" is used in Base64 encoding and will not work.
Which characters or symbols or totally strange hieroglyphs are not used in Base64 encoding?
How can guarantee access to the properties 
Anyone ever played that game?

You should be able to convert the string "bla=1" to Base64 and back, regardless of the equal-sign within that string. Did it fail, and if so, what error did it generate?

 sometimes its simpler than expected. Have I thought of doing it this way?
You're right, I could convert the complete string. Right now I'm just converting the value - this looks like "label.text=qwertzwtf==". This has the opportunity of deleting certain entries when needed. The values are not predefined, admin users (our crew) are able to add additional entries by using a dialog. Simple users (customers) should not be able to manipulate out those values(safety reasons).
I figured out (try&error) that the "@"-symbol is pretty safe, so I changed my properties to "label.text@qwertzwtf==". works like a charm so far

Torsten

Sounds like a convenient solution to a common problem

just the regular magic... I 'll leave it to the "@" and wait for the QC department to find out if it works

why would you? the first equal sign would be your separator, what is to the left of it would be the key (the name), what is to the right of it the base64-encoded value.
the advantage is the structure of your file remains intelligible.
