Doubt in java.util.Properties
I have a configuration file which consists of name & value pairs. For editing this file i am using Properties class. The problem is , when it finds any property value which consists of character : (colon), its automatically inserting \ (backslash) before the colon(:). How can i get rid of this problem. Any help is highly appreciated. Thank you
Well, basically that's part of the formatdefinition
that Properties uses. If you don't do it, then you
aren't really using Properties format and you'llhave
to do your own IO.Thanks for the reply. Is there anyother api or class
that can be used to resolve my problem.What is the problem? A character is escaped, but you will get : when you read the value. You don't have a problem as long as all reading / writing is done through that class.

Finding the key according to string length in java.util.Properties
Finding the key according to string length in java.util.Properties.
I know only String length only.i need to retrieve the values from the java.util.properties.
we know that we need to give the key value in order to retrieve the datas.
but my problem is i will give the length of the key instead of giving the key value but i need to retrieve the datas according to the length of the key. -
Java.util.Properties methods load & store
Does java.util.Properties methods load & store produce & load platform independent code?
You mean that it is better to use loadFromXML(InputStream in) and storeToXML(OutputStream os, String comment) methods of this class in order to have platform independent code?

Java.util.properties ? Using Config.getProperty
Hi all,
This one has been causing me a bit of a headache! I am using the Java.util.properties to create a file which looks like this:
#Tue Sep 13 19:15:06 GMT+02:00 2002
User=tristan
Password=bristol
Name=Tristan\ Webb
Rights=Tristan\ Webb
#Tue Sep 13 19:15:35 GMT+02:00 2002
User=adam
Password=newcastle
Name=Adam\ Jones
Rights=Adam\ Jones
The problem comes when I try to read the information back and put it in a Vector. Using the code below, it only ever puts the last users details (i.e. adam, Newcastle etc..) into the file and skips the first one. I have tried adding more users details, but it only ever reads the last entry. Is there anyway of forcing the config.getProperty to read the first entry in the file and then all the subsequesnt user details ?? I am thinking there must be a way of looping through the file, but im not sure where to start and am quite lost!
Many Thanks,
Properties config;
FileInputStream file;
file = new FileInputStream("password.cfg");
config = new Properties();
config.load(file);
User2 = config.getProperty("User");
Password = config.getProperty("Password");
name = config.getProperty("Name");
rights = config.getProperty("Rights");
UserDetails user = new UserDetails(User2, Password, name, rights);
userDetails.add(user);The java.util.Properties class works like a dictionary: it stores values, which you can access using the keys.
The keys must be unique. In your case, the keys are not unique. If you do: String s = config.getProperty("User"); then how do you expect to get two values back (tristan and adam)?
You must make the keys unique in some way. For example, write your properties file like this:
#Tue Sep 13 19:15:06 GMT+02:00 2002
User.1=tristan
Password=.1bristol
Name.1=Tristan\ Webb
Rights.1=Tristan\ Webb
#Tue Sep 13 19:15:35 GMT+02:00 2002
User.2=adam
Password.2=newcastle
Name.2=Adam\ Jones
Rights.2=Adam\ Jones
Now use for example: String s = config.getProperty("User.1"); to get the name of the first user, etc.

Applet using java.util.Properties.setPropterty()
Hi,
I'm trying to use the java.util.Properties class in an Applet. More specifically the setProperty(String, String) method. My applet compiles fine but it crashes when I run it with IE (ver. 6). It shows an "NoSuchMethodError: method setProperty(Ljava.lang.String,Ljava.lang.String)". When I compile with javac, it doesn't complain but I guess the IE VM doesn't see that method. But Properties is part of java.util.*, so shouldn't IE have access to that class?
Any help is much appreciated?
Thanks
HeatherThe API for that method includes this:
Since:
1.2
That means it's a Java 2 method. The JVM in Internet Explorer doesn't support Java 2 methods (unless you load a plugin that does). -
Retrofitting java.util.Properties
Hi all,
why was java.util.Properties in JDK 1.5 not retrofitted to implement java.util.Map<String,String>?
This would have been the "natural" way to take advantage of typesafety.
I'm sure this has something to do with backwards compatibility, but what exactly woud it break?
Thanksjava.util.Properties extends java.util.Hashtable
java.util.Properties : private java.util.HashtableWhat does that actually buy you though?
I mean its really the difference between:
class Properties {
final Hashtable m_contents = new Hashtable();
public String getProperty(String key) {
return (String) m_contents.get(key);
}vs.
class Properties private extends Hashtable {
public String getProperty(String key) {
return (String) super.get(key);
}Which is nice and all, but it strikes me as syntactic sugar more than anything else.
I don't disagree: Properties should never have extended Hashtable, it should have encapsulated a Hashtable. Also Stack should not extend Vector, Booleans should not have a public constructor, it would even have been nicer if people actually used the Dictionary interface occassionally in 1.0/1.1.
Its easy to say these things now with the benefit of 20-20 hindsight. -
Invalid data returned when iterating a java.util.Properties
Hi all,
I'm having trouble iterating thru the values in a java.util.Properties object.
This problem only occurs when passing in a java.util.Properties object into the constructor of a java.util.Properties.
Here's some example code. (A picture is worth....)
<pre>
import java.util.Properties;
import java.util.Iterator;
public class PropertyTest {
public static void main(String[] args) {
Properties validProp = new Properties();
//add some data
validProp.put("key1", "key1Value");
validProp.put("key2", "key2Value");
validProp.put("key3", "key3Value");
System.out.println("This will iterate...");
dumpPropertyFile(validProp); //This will iterate correctly
Properties inValidProp = new Properties(validProp);
System.out.println("This doesn't iterate correctly");
dumpPropertyFile(inValidProp); //This will not iterate
public static void dumpPropertyFile(Properties prop) {
Iterator iter = prop.keySet().iterator();
while (iter.hasNext()) {
String key = (String)iter.next();
System.out.println(key + "=" + prop.getProperty(key));
</pre>
I have searched the bug database, but didn't find any open bugs related to this issue.
Could someone let me know if this is a existing bug or has this bug already been addressed.
My setup.
NT 4.0 / jdk1.3.1
Thanks,I found this works.
Iterator e = _props.keySet().iterator();
while(e.hasNext())
String str = (String)e.next();
System.out.println("key(" + str + ")=" + _props.getProperty(str));
but the display sequence is always in descending order ???
Anyone has a clue ?

Java.util.ResourceBundle VS java.util.Properties
I want to keep some key values pair outside program in a properties file and use that in my program. There is no requirement of localization. Should i use ResourceBundle or Properties class? Previously I have used Properties class for this purpose but in my current project ResourceBundle is being used. Is there any benefits in using ResourceBundle? will it be faster to read properties using ResourceBundle?
ResourceBundles support internationalization. If you know that don't need it and Properties suffice, okay then.
Forget about "fast", both will have to read from the disk (slow) and both will use hashmaps (fast look-up). And both will probably do it in the same way. -
I execute this piece of code on application startup
public final Properties loadProperties() throws VmsBaseException {
Properties prop = new Properties();
prop.setProperty("ei.properties.file.import.path", "C:/projects/folders/input");
prop.setProperty("ei.properties.file.output.path", "C:/projects/folders/output");
prop.setProperty("ei.properties.file.name.pattern", "*.xml");
prop.setProperty("ei.properties.fixed.delay", "6000");
prop.setProperty("ei.properties.file.poller.interval", "100");
prop.setProperty("ei.properties.file.archive.path", "C:/projects/folders/archiveFolder/");
prop.setProperty("ei.properties.file.error.path", "C:/projects/folders/errorFolder/");
return prop;
Later on I would like my other beans to get hold of this properties and use the value inside it.
Any Idea how to achieve itManjit wrote:

Any Idea how to achieve itYes, put the properties object somewhere where you can always reach it. Either that or let any piece of code that needs it call your loadProperties() method.
I'm sorry but your question is very open ended, so it is nearly impossible to be more specific. -
I have an Integer array that i want to store using properties.
At the moment i have something like this
for(int i = 0; i < guitarNo.length; i++) {
p.setProperty("Identification", Integer.toString(guitarNo));
}But it doesn't store any of the ids it simpily stores as 1
Anyhelp would be fantasticbulger2503 wrote:
Ah well thats an inconvenience :)
Could you suggest another way?Maybe you could build a Properties file like the following given an e.g guitarNo like { 21, 54, 41 }
guitarNo = 3
Id0 = 21
Id1 = 54
Id2 = 41When you have to read the values back again, first read the key "guitarNo", create your array and read the keys "Id"+i for i in in [0,3)
