How To Implement UNDO Feature
Mar 10, 2014I need to design 'notepad' application as my assignment.
Requirement: Only text is allowed, all the characters are having same size and font. It should have feature like new, open, save , save as , exit , UNDO , find , replace and font.
For this i use JTextArea and menu bar .
I am able to develop features like new, open, save , save as , exit. Need to implement now UNDO , find , replace and font but struck at 'UNDO'.
UNDO feature should be enable only when user writing in the writing area but not when it opens any file. What i thought is to have a flag on whenever user save whatever he wrote and if he use select UNDO then it check for the flag. If flag is ON then it will not do UNDO and if flag is not set then it cleared everything from the Text Area.

EJB / EE :: Maintaining Values From Primefaces Form After Form Submit
Jan 29, 2015I have a form containing several fields, 2 of which persist to different table in a database than the rest of the fields on the form. I have no problem persisting the data into both tables of the database, and after the form is submitted I reset the form to its default values. That all works fine.
But in the same session, when I open another form (a search form) and enter search criteria, which then displays a datatable containing the search results, those 2 values that are persisted to another table are not showing up, but the rest of the data is.
Here is the method that calls the persist methods:
@ManagedBean(name = "foreignPartyController")
@SessionScoped
public class ForeignPartyController implements Serializable {
...
public void saveData() {
[Code].....
The values do show up, but the problem is, when a subsequent form is opened in the same session (e.g. a search form) the field for that value shows the actual value, instead of the field being blank.'
I am not sure why the data from the one database ("parent") is showing up, yet the data from the other database ("child") is not.
Is it something I am doing wrong? I thought by setting the setter in the child controller class back to a new instance of the Entity class (PolicyPayment) that it would reset the form to default values, but at the same time retain (or save) the inputted values in the same session.

Erasure Feature From Generics - Duplicated Bound Error
Jun 14, 2014The erasures of all constituent types of a bound must be pairwise different, or a compile-time error occurs.
Well I know what type erasure is, and I think I kind got what this statement means. My understanding from it is that if your type parameter has more than one bound and those bounds occurs to be the same type after erasure that is a compile-time error. Is that it?
The only thing I could found related is something like this:
class A<T extends List<Integer> & List<Integer>>{
}
Which as you might know gives the Duplicated bound error.
Which Iterator To Be Use To Create Instances From Feature Value Pairs (Mallet API)
Mar 12, 2015I am tring to run LDA to generate some topics from txt files as the following one:
Document1 label1 forest=3.4 tree=5 wood=2.85 hammer=1 colour=1 leaf=1.5
Document2 label2 forest=10 tree=5 wood=2.75 hammer=1 colour=4 leaf=1
Document3 label3 forest=19 tree=0.90 wood=2 hammer=2 colour=9 leaf=4.3
Document4 label4 forest=4 tree=5 wood=10 hammer=1 colour=6 leaf=3
Each numeric value in the file is an indication of the number of occurrences of each feature (e.g., forest, tree) multiplied by a given penalty. To generate instances from such a file, I use the following Java code:
String lineRegex = "^(S*)[s,]*(S*)[s,]*(.*)$";
String dataRegex = "[p{L}([0-9]*.[0-9]+|[0-9]+)_=]+";
InstanceList generateInstances(String dataPath) throws UnsupportedEncodingException, FileNotFoundException {
ArrayList<Pipe> pipeList = new ArrayList<Pipe>();
pipeList.add(new Target2Label());
[Code] .....
I then add the so-generated instances to my model using the instruction model.addInstances(generatedInstances). The resulting output is described below.
It contains errors caused by the instruction model.addInstances(generatedInstances). Debugging my code showed me that the alphabet associated to the model is null. Am I using the wrong iterator?
name: document1
target: label1
input: TokenSequence [forest=3.4 feature(forest)=3.4 span[0..10], tree=5 feature(tree)=5.0 span[11..17], wood=2.85 feature(wood)=2.85 span[18..27], hammer=1 feature(hammer)=1.0 span[28..36], colour=1 feature(colour)=1.0 span[37..45], leaf=1.5 feature(leaf)=1.5 span[46..54]]

Servlets :: Feature Detection - Determine Browser Type
Apr 22, 2014I need to be able to detect IE 9, IE 10, IE 11 and the latest from Firefox and Chrome. The old method using the user-agent string is unreliable and not recommended.

I can write it myself, or if there is a handy dandy API using feature detection already written that would be OK too.

How To Create Withdraw / Deposit Feature So It Can't Exceed Maximum Limit
Nov 25, 2014So lets say I got maximum of 20 deposit, I want to create a method/function (idk what proper name for it is) so that you cannot deposit more than 20 nor withdraw more than you have in your account, so this function checks your account, if your total is for example 18 and you're trying to deposit 10, it rejects it and doesn't add to your total and pops up with a message, vice versa for withdraw.
This is what I have so far
Not I already have the maximum limit + total feature created just not displayed here
public void depositMoney (int dMoney) {
if(DMoney > 0 ) {
totalMoney = totalMoney + dMoney;
}
else {
System.out.println("Please insert money more than 0");

JDBC :: Uploading Template File Into Database Using SetBlob Or SetBinaryStream

I'm using :
Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - 64bit Production
Weblogic Server Versions: 10.3.0.0 with Java 1.6.0_05
The driver class name for the weblogic datasource: weblogic.jdbcx.oracle.OracleDataSource
Initially, I tried:
sqlQuery = new StringBuffer();
ps = null;
sqlQuery.append("insert into KATET_REPORTS (FILE_DATA)");
[Code] ....
This failed, so I changed ps.setBlob(1,is)
to
ps.setBinaryStream(1,is). This failed as well with teh same error, just for setBinaryStream instead of setBlob.
Is there a known inconsistency between that driver and this Weblogic version? Is there something else going on? If I haven't given enough data to debug the issue here, what other data should I gather?

View Replies View RelatedServlets :: How To Get Result When Website Initially Uploading Rather Than Pressing Button For Action
Oct 28, 2014I am learning how to program in JAVA servlet+MySQL. Decided to make a simple program where it shows who is celebrating birthday today by retrieving data from database. At the moment I managed to get it working by loading a form.html and pressing the button in it which gets to the result.jsp and shows results there.
My plan was to get a list of people who are celebrating there birthdays initially when the website is loaded/being loaded, I mean when you enter URL into your web browser and you get it instantly in browser. Is there a way to do it the way I want (JAVA+servlet+MySQL) instead of pressing a button/link?

How To Turn Image Into Tiled Image
Nov 21, 2014I'm trying to make a method that takes an image and turns it into a tile image. So if the original image looks like this:
[URL] ....
then the output image should look like this:
[URL] ....
Here's a method that's supposed to do that but for some reason the output image looks the same as the original:
public static int[][] tile(int[][] arr){
int[][] tile = new int[arr.length][arr[0].length];
for (int i = 0; i < arr.length; i++) {
tile[i]=arr[i];
}
return tile;
}
I recently changed the method and the error message I'm getting is "bad operand types for binary operator '+'. Here's the method:
public static int[][] tile(int[][] arr){
int[][] tile = new int[arr.length][arr[0].length];
for (int i = 0; i < arr.length; i++) {
for(int j=0; j<arr[i].length;j++){
tile[j]=(tile[j])+(arr[i]);
}
}
return tile;
}
