JTextField(Document, string, int)

Dear friends,
Could you just tell me how can I fix the size of the JTextField,
such as just accept the maximum number of digits or characters in JTextField...
I cant create the Document....
Could anyone give me a tips?

I found the best way to do this is to subclass PlainDocument as follows:
public class MyTextDoc extends PlainDocument
 int maxCharacters;
 public MyTextDoc(int maxChars) {
 maxCharacters = maxChars;
 public void insertString( int offs, String str, AttributeSet a )
 throws BadLocationException {
 if( (getLength() + str.length()) <= maxCharacters)
 super.insertString(offs, str, a);
 else
 Toolkit.getDefaultToolkit().beep();
}I then use this document in the constructor for all my JTextFields.
I'm not sure what you mean by "I cant create the Document...."
Cheers
Gary

String & Int in Bean

Hi,
i'm building a webapp to simply allow the user to enter his or her details which will be submitted with all the details stored in the bean. When deciding to either make properties such as age or telephone number as string or int in a bean, i read somewhere that it is a rule of phumb to set these properties as Strings as they are easier to validate. If that is the case, if i create a property of String age with it's corresponding getter and setter method i.e
public void setAge(String n) {
    age = n ;
public String getAge()
   return age;
doing something like the above would not convert the value into an int which is what i would like to do. Therefore, i was thinking of doing the following in my bean class:
package beans ;
public class Person
private int age ;
// Constructor
public Person() {
    age = 0 ;
public void setAge(int n) {
    age = n ;
public void setAge(String s) {
    try {
      age = Integer.parseInt(s) ;
    catch (NumberFormatException e) {}
public int getAge() {
    return age ;
}doing the above would i think be more convenient. Would that be the better way do you think?
cheers

There's nothing wrong with what you are doing, however.I disagree. First that code doesn't belong in a bean. An then it has to be dupilcated across every bean and every "int" property. Plus I disagree with the way it swallows formatting errors.BigXXXXXwhatever...... what do you mean by that code does not belong in the bean. I've seen my example duplicated in many exampls and in books. I'm not to concerned if it has to be duplicated in every bean and int, it's not what i was asking.
In terms of the fomatting errors, what errors? Do i need to correct something?
Thanks for your input raychen.

JSP Strings, Ints converting

I'm sure this sort of thing has been asked but i cant find it in the forums.... I'm trying to read in a string from a form and then convert it to an int so that i can use it in a select statement so i can compare it to a field declared as "Number" in the Access Database.
String sess = request.getParameter("num"); //num comes from form
int eventNum = Integer.parseInt(sess);
//connected ot the database
String query = "SELECT * FROM EVENT WHERE event_id = 'eventNum' ";
ResultSet result = stmt.executeQuery(query);
//event_id is a number in the database
Its saying "Data type mismatch in criteria expression"
Thanking you in advance,
Brian

Since you are building a string as query, you don't need to convert it
String sess = request.getParameter("num"); //num
String query = "SELECT * FROM EVENT WHERE event_id ='eventNum' ";
ResultSet result = stmt.executeQuery(query);This error "Data type mismatch in criteria" comes from event_id = 'num'
event_id is numeric, so it should not contain quotes in the sql statement
this will do it:
String query = "SELECT * FROM EVENT WHERE event_id =" + sess

Sounds like that JDBC driver doesn't support getting auto-generated keys. - MOD

Convert an int to a String

Hi,
when i try to do the following its an error
int totalmarks;
String Totalmarks;
Totalmarks = totalmarks.toString();
could any one tell me how to do it correctly
Thank you

A lot of alternatives, but you can't do new String(int..).
1. Integer.toString(totalmarks)
2. String.valueOf(totalmarks) will call Integer.toString(totalmarks)
3. ""+totalmarks will use the StringBuffer and append "" and totalmarks which again will call String.valueOf(totalmarks) which again will call Integer.toString(totalmarks)

Compilation Error while using string (Please help)

Hi,
I am using "Sun WorkShop Compiler C++ SPARC Version 5.000". Compiling code which contains a "string variable" throws the following error:
"/opt/WS5/SC5.0/include/CC/./new", line 32: Error: The prior declaration for ope
rator new(unsigned) has no exception specification.
"/opt/WS5/SC5.0/include/CC/./new", line 34: Error: The prior declaration for ope
rator delete(void*) has no exception specification.
"/opt/WS5/SC5.0/include/CC/./new", line 36: Error: The prior declaration for ope
rator new[](unsigned) has no exception specification.
"/opt/WS5/SC5.0/include/CC/./new", line 38: Error: The prior declaration for ope
rator delete[](void*) has no exception specification.
4 Error(s) detected.
The command used for compilation is :
/opt/WS5/bin/CC -compat=4 -I/opt/WS5/SC5.0/include/CC -features=%all try.cpp
Would help if I could get some comments on the above.
Thanks and Regards,
M Shetty

There is a requirement that I use the Workshop 5.0
compilere with option "-compat=4".
The program I am trying to compile contains:
#include <string>
int main()
string test = "aaa";
return 0;
There is no "string" in "-compat=4". You need to
do something like this:
// --- start test.cc ---
#include <rw/cstring.h>
int main()
RWCString test = "aaa";
return 0;
// --- end test.cc ---
CC -compat=4 -library=rwtools7 test.cc

How to parse select lines in an html string?

I've been writing a program to deal with demographic data and the first server it calls returns an xml string. However, the backup server returns an html string instead of an xml string, so the formatting is a bit different. I was going to use a regex as I did with the xml server, but regex's don't work that well with html. i was wondering if you could offer some advice on how to effectively parse the html string? It is in this format <html>

}Currently it functions using a regex, and executes, but doesn't return any numbers, only returns zeros...If you could help me out with this, that would be amazing! Thanks so much.

hmm, is there a way to do it without an external API? Of course there is.
looks like i have to download the API and the idea behind the program is to make it so multiple people running only java can run the program, without having to download APIs, ect, to make it run. Not sure if that is what JTidy entails, but is that what you were suggesting?Personally, I don't understand the resistance to using well-tested tools already in existence as opposed to trying to rewrite a shallow facsimile of said tools. You can distribute the JTidy library along with your application and save yourself a great deal of development and debugging effort.

Having problem with UDF, getting unwanted result Ljava.lang.String;@25c560

Hi,
This is atually a follow-up to other post in the same forum: Sending XMl message as text (Mail body) by receiver mail adapter
We are having problem with UDF to get correct output.
We are getting result of UDF as below:
[[Ljava.lang.String;@f37573 [Ljava.lang.String;@1a409ed [Ljava.lang.String;@87c011 [Ljava.lang.String;@52a077 [Ljava.lang.String;@a4e8e5 [Ljava.lang.String;@f37573 [Ljava.lang.String;@1a409ed [Ljava.lang.String;@87c011 [Ljava.lang.String;@52a077 [Ljava.lang.String;@a4e8e5 [Ljava.lang.String;@f37573 [Ljava.lang.String;@1a409ed [Ljava.lang.String;@87c011 [Ljava.lang.String;@52a077 [Ljava.lang.String;@a4e8e5 [Ljava.lang.String;@f37573 [Ljava.lang.String;@1a409ed [Ljava.lang.String;@87c011 [Ljava.lang.String;@52a077 [Ljava.lang.String;@a4e8e5 ]

And following is the UDF we are using:
=========================================
String mailBody = new String();
int inta, intb, intc, intd, inte;
inta = a.length;
intb = b.length;
intc = c.length;
intd = d.length;
inte = e.length;
for(int i = 0; i < a.length; i++)
mailBody = mailBody + a + " " + b + " " + c + " " + d + " " + e + " ";
result.addValue(mailBody);
====================================
Any help to resolve this would be very helpful.
Thanx
Sue

Hi Bhavesh,
We are getting following error if we use the UDF you given below:
Check Result for Object test Source code has syntax error: D:/usr/sap/XID/DVEBMGS00/j2ee/cluster/server0/./temp/classpath_resolver/Mapf2026120390a11db9d1f000e7f22e9d4/source/com/sap/xi/tf/_test_.java:75: a is already defined in testUDF$(java.lang.String[],java.lang.String[],java.lang.String[],java.lang.String[],java.lang.String[],com.sap.aii.mappingtool.tf3.rt.ResultList,com.sap.aii.mappingtool.tf3.rt.Container) int a = a.length(); ^ D:/usr/sap/XID/DVEBMGS00/j2ee/cluster/server0/./temp/classpath_resolver/Mapf2026120390a11db9d1f000e7f22e9d4/source/com/sap/xi/tf/_test_.java:75: int cannot be dereferenced int a = a.length(); ^
We have no knowledge of java at all.
We did some modifications to it as below:
String mailBody = new String();
int a = a.length();
int b = b.length();
int c = c.length();
int d = d.length();
int e = e.length();
for(int i = 0; i < a.length(); i++)
mailBody = mailBody + a + " " + b + " " + c + " " + d + " " + e + " ";
result.addValue(mailBody);
It it didn't work. Think we are missing something. Can please help us to figure it out.
Thanx
Sue

'int' not serializable!?

Hello all,
When deploying my application to WLS 8.1, I keep getting warnings along the lines of
<Warning> <EJB> <BEA-012034> <The Remote interface method: '//snip// Foo.bar(java.lang.String,int) throws java.rmi.RemoteException //snip// contains a parameter of type: 'int' which is not Serializable. Though the EJB 'Foo' has call-by-reference set to false, this parameter is not Serializable and hence will be passed by reference. A parameter can be passed using call-by-value only if the parameter type is Serializable.>
This message completely confuses me. Since 'int' is a primitive, it cannot implement the Serializable interface. On the other hand this is not necessary since the JVM knows how to serialize primitives anyway. Furthermore, primitives are by Java specification always passed by value.
My assumption is that this message is essentially bogus, a weblogic bug if you want, and the int parameter will indeed be passed by value no matter what the warning says. I just cant se how WLS could pass it by reference given that it is running on a VM that implements the java standard.
Am I missing something here? Please give me your thoughts on this one. We have a customer who is very concerned about these warnings showing up in the log...
Thank you

Hello, and thanks for taking a stab at this.
While it is great that the fix you ar putting into SP5 allows the administrator to supress BEA-012034 warnings all together, would it not be better to simply correct the code not to issue BEA-012034 warnings for ints, floats and other primitives? Enabeling your fix would indeed make these incorrect messages go away, but it will also supress correct BEA-012034 warnings should our ejb interface [heaven forbid :] contain non-serializable objects.
thanks

How to increase the size of a String[]

I'm using a String[] variable that I do not know the maximal size, but i need to increase its size, how can I do that
ex:
String[] buffer = new String[]
int i= 0;
while (<condition>) {
???? // increase the size
buffer [ i ] =.....
}

There is no way in Java to actually increase or decrease the size of an existing array. You'll have to create a new array of the appropriate size and copy elements of the first array into it, for example by using System.arraycopy.
Or you could give your array a big enough size at start, so you won't have to do the above.
A better idea would be to use a collection instead of an array (like an ArrayList) in the first place.

Concatinating numbers with a string...sort of

Well I've got an assignment that says this "Write a method called multiConcat that takes a string and an interger as parameters. Return a string that consists of the string parameter concatenated with itself count time, where count is the integer parameter. For example, if the parameter vales are 'hi" and 4, the return value is "hihihihi". Return the original string if the interger parameter is less than two.
So I've tried a couple of things that I thought would work with my small amount of CS courses, but I have not been able to come up with a resolution for this assignment yet. I do not want anyone to post any time of code yet. All I ask for is for someone to point me in the correct direction with some kind of a learning document etc.

for that the answer is
class MyClass{
 StringBuffer string1=null;
public StringBuffer myMethod(String string , int number){
string1=new StringBuffer(string);
 if (number<2){
 return string1;
 }else{
 while(number!=1){
 string1.append(string);//here string is String and string1 is StringBuffer tehn only we can get coorect data.then u will get output hihihihi for input hi,4
 //try it by keeping both of type stringBuffer, u will get out put hihihihihihihihi for input hi,4
 --number;
 return string1;
class FirstProgram {
 public static void main(String[] args) {
 String string=args[0];
 int number=Integer.parseInt(args[1]);
 System.out.println("string ="+string+" "+"number ="+number);
 StringBuffer result=(new MyClass()).myMethod(string,number);
 System.out.println("final output is"+result);
}

How do you removing special characters from a string

hi,
i'm a novice to java, if you couldn't tell. i need to write a program to recognise palindromes (eg. madam etc.) but i can't work out how to strip or clean the input string of white space or punctuation. any help appreciated. by the way, any other ideas on how to go about it?? (i don't expect it to be done, just after guidance)
my thanks in advance

OK Here you are:
protected static String removeJunk(String string)
          int i, len = string.length();
          StringBuffer dest = new StringBuffer(len);
          char c;
          for (i = (len - 1); i >= 0; i--)
               c = string.charAt(i);
               if (Character.isLetterOrDigit(c))
                    dest.append(c);
          return dest.toString();
Klint
