InputStream from a String?

Hi all,
does anybody know how you would go about getting a java.io.InputStream from a string object? I know you can create a StringReader from a string, but the StringBufferInputStream is depreciated. I want to parse an xml String with the DocumentBuilder class, but it only takes an InputStream object, not a Reader object.
any suggestions?
thanks,
J

Adding to Mr. Sampieri's explanation:
The encoding is specified in the initial processing instruction of the XML. If absent, the default encoding is UTF-8. (The default encoding of Java depends on the locale, so it's better to specify the correct encoding when writing your program.)
Check if the names of the XML encodings are different from the names of the Java encodings (charsets).
<?xml version="1.0" encoding="ISO8859-1" ?>

InputStream from String via StringReader ?

Hello, i d like to know how to create an InputStream from a String via StringReader ?
Thanks

Hello, i d like to know how to create anInputStream
from a String via StringReader ?
ThanksYou can't.So why does it say like this in the api for
StringBufferInputStream ?a) this was not your original question
b) "Deprecated. This class does not properly convert characters into bytes. As of JDK 1.1, the preferred way to create a stream from a string is via the StringReader class. "
So you can use that class but it will be wrong. You should not use streams for characters. You should use Readers and Writers.

This is very simple, it isn't buffered, but it should work for you.
Sting s = editfield.getText();
for(int i=0; i<s.length();i++) fw.write((int)s.charAt(i));
fw.flush();
fw.close();

How to create an XML document from a String.

Can anyone help,
     In the Microsoft XML Document DOM there is a load function load(string) which will create an XML document, but now we are switching to Java and I do not know how to create and XML document from a string, this string �xml document� is passed to my program from a webservice and I need to read several xml elements form it in a web server.
This string is a well formatted XML document:
<?xml version="1.0" encoding="UTF-8"?>
<Countries NumberOfRecords="1" LanguageID="en-us">
     <Country>
          <CountryCode>AU</CountryCode>
          <CountryName>AUSTRALIA</CountryName>
     </Country>
</Countries>

Thanks PC!
I made it work using:
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
DocumentBuilder builder = factory.newDocumentBuilder();
factory.setIgnoringComments(true); // We want to ignore comments
// Now use the factory to create a DOM parser
DocumentBuilder parser = factory.newDocumentBuilder();
//TransformThisStringBuffer is a string buffer wich contain the 'XML document (String)'
InputStream in = new ByteArrayInputStream(TransformThisStringBuffer.toString().getBytes());
// Parse the InputStream and build the document
Document document = parser.parse(in);
But which one is faster InputSource or InputStream, were would you put the "new InputSource(new StringReader(yourString))" in the above code?

Parsing XML from a String

I have a servlet, this recieves an XML file from the client as a file input type from a html form. This XML is wrapped up in http headers and stuff. I parse the input stream from the client's http request to get a string containing the xml. This is fine.
How do I now build an XML document from this string? The DocumentBuilder will take in files and InputStreams but I can't find anything that helps me?
The only solution I've come up with is to write out the string to a temp file and then parse it back into a Document.
Any ideas anyone?????

Document doc = documentBuilder.parse(new InputSource(new StringReader(yourXMLString)));
voila!

How to get InputStream from a file with absolute path?

Hi, guys:
If I have file with a absolute path that may be inside/outside
my Eclipse plugin, I want to get an InputStream from it. It just keeps giving me null for "is":
String absFilePath = "/D:/my_dir/.../sample_file.txt";
InputStream is = getClass().getResourceAsStream(absFilePath);
regards,

Don't use resource as stream if you have an absolute path, use FileInputStream.

JAXB: Read XML data from a String?

Hi,
I get XML data not from file but as a string and I wanted to use JAXB to parse it and get my Java Objects.
The unmarshall methods wants an "InputStream", but "StringBufferInputStream" is deprecated, so that I don't know a way to use my String as InputStream.
Can someone give me a hint other then writing the data in a file first?

Hi FrankSch,
The unmarshall methods wants an "InputStream", but
"StringBufferInputStream" is deprecated, so that I
don't know a way to use my String as InputStream.
Can someone give me a hint other then writing the data
in a file first?Yes, the class StringBufferInputStream is deprecated, and the deprecation notice reads:
Deprecated. This class does not properly convert characters into bytes. As of JDK 1.1, the preferred way to create a stream from a string is via the StringReader class.
The JDK API usually mentions an alternative to the deprecated method/class and in this case, you should use java.io.StringReader. It has one constructor and should suite you nicely:
StringReader(String s) That way, you get an InputStream object; you can now use JAXB.
Hope this helps,

Replacing a set of characters from a string in oracle sql query

I want to replace a set of characters ( ~ ! @ # $ % ^ * / \ + : ; | < > ? _ ,) from a STRING in sql
select 'TESTING ! ABC 123 #'
FROM DUAL;
What is the best way to do it? Please provide examples also.

What is your expected output... The query I posted just removes them, it never replaces them with spaces..your string already has space.. if you want to remove space as well .. try this...
SELECT TRANSLATE ('TESTING ! ABC 123 #', '-~!@#$%^*/\+:;|<>?_, ', ' ') FROM DUAL;
Output:
--TESTINGABC123
Else post your expected output..
Cheers,
Manik.

Problems with Reflection API and intantiating an class from a string value

I want to instantiate a class with the name from a String. I have used the reflection api so:
static Object createObject(String className) {
Object object = null;
try {
Class classDefinition = Class.forName(className);
object = classDefinition.newInstance();
} catch (InstantiationException e) {
System.out.println(e);
} catch (IllegalAccessException e) {
System.out.println(e);
} catch (ClassNotFoundException e) {
System.out.println(e);
return object;
Let's say my class name is "Frame1".
and then if i use:
Frame1 frm = (Frame1) createObject("Frame1");
everything is ok but i cannot do this because the name "Frame1" is a String variable called "name" and it doesn't work like:
name frm = (name) createObject("Frame1");
where i'm i mistaking?
Thanks very much!

i have understood what you have told me but here is a little problem
here is how my test code looks like
Class[] parameterTypes = new Class[] {String.class};
Object frm = createObject("Frame1");
Class cls = frm.getClass();
cls.getMethod("pack",parameterTypes);
cls.getMethod("validate",parameterTypes);
everything works ok till now.
usually if i would of had instantiated the "Frame1" class standardly the "cls" (or "frm" in the first question ) object would be an java.awt.Window object so now i can't use the function (proprietary):
frame_pos_size.frame_pos_size(frm,true);
this function requires as parameters: frame_pos_size(java.awt.Window, boolean)
because my cls or frm objects are not java.awt.Window i really don't find any solution for my problem. I hope you have understood my problem. Please help. Thanks a lot in advance.

Getting char values from a string problem

Hi,
Here's an example of what I'm trying to do:
boolean loopSwitch = true;
while (loopSwitch)
     String orderDecider = JOptionPane.showInputDialog (null, "Would you like your numbers to be ordered in   ascending or descending order(A/D)",      "Order decision", JOptionPane.QUESTION_MESSAGE);
     if (orderDecider == A)
     loopSwitch = false;
     }I basically want the user to input either a/A/d/D and to get the char values from the string so I can use them in an if statement.
Basically, I wanna parse the string into a char.
Is this possible?
Thanks.
Edited by: xcd on Oct 16, 2009 8:38 AM

Why not just use the String.equals() method to compare a String to a String?
But if you must, you can use the String.charAt() method to return a char at a particular location in the String.
Note: char literals need to be surrounded by single quotes ('A') and String literals need to be surrounded by double quotes ("A").

Removing Null values from character string

Hi All,
Can i remove NULL values (hexadecimal - 0000) from character string. I am uploading a file from presentation layer (shared server) and getting NULL values in many fields which i want to remove.
please assist.
Thanks for you help..

Hi,
Most likely, nobody needed it, but if anybody in future will need the solution for related problem - here's solution:
data: lv_nullchar type xstring value '0'.
shift lv_xstring right deleting trailing lv_nullchar in byte mode.
shift lv_xstring left deleting leading lv_nullchar in byte mode.
This hack deleting null chars in lv_xstring at end file and at begining of file. Works perfect for me, where i also worked with files.

Escape single quote from a String variable

Hi,
I have a String variable called "name" which i am using in my form tag.
<form name=test action="test.jsp?fname=<%=name%>" method="post">
But i am getting Javascript error if the "name" variable contains a string with some special characters like single quote( ' ).
Plz help me to escape this special char from my String variable.
Thanks..

You need to url-encode the value using the URLEncoder class.
http://java.sun.com/javase/6/docs/api/java/net/URLEncoder.html
For example:
<form name=test action="test.jsp?fname=<%=URLEncoder.encode(name, "ISO-8859-1")%>" method="post">

How do I make a Datagram Packet from a String?

I am looking to make a Datagram Packet from a string. If I send a command to a server that allows remote connections via UDP, such as "restart" it will restart the server. I can accomplish this easily through the fput() method of PHP.
I want a Java version of my utility, and am using the DatagramSocket and DatagramPacket classes. I see that I need to make a byte array and put it inside a DatagramPacket. How would I go about putting the string "restart" into a byte array?
Thanks,

Use the following code to send a Datagram:-
import java.io.*;
import java.net.*;
// This class sends the specified text as a datagram to port 6010 of the
// specified host.
public class UDPSend {
    static final int port = 6010;
    public static void main(String args[]) throws Exception {
        if (args.length != 2) {
            System.out.println("Usage: java UDPSend <hostname> <message>");
            System.exit(0);
        // Get the internet address of the specified host
        InetAddress address = InetAddress.getByName(args[0]);
        // Convert the message to an array of bytes
        int msglen = args[1].length();
        byte[] message = new byte[msglen];
        args[1].getBytes(0, msglen, message, 0);
        // Initilize the packet with data and address
        DatagramPacket packet = new DatagramPacket(message, msglen,
                               address, port);
        // Create a socket, and send the packet through it.
        DatagramSocket socket = new DatagramSocket();
        socket.send(packet);
}This uses argments, if you want a string change the code accordingly.
