How to get a edited string to be evaluated again

hello, I'm very new to TS and don't know if I express the problem clearly. however the question below:
I try to edit a numeric variable before it's evaluate at runtime and what i did is:
Val(SearchAndReplace("FileGlobals.I_LB_bin[FileGlobals.loop_BINi]","LB",FileGlobals.Mode[Locals.modei]))/2
but after the replacement seems the val function can get value with new string.
how can i get a string to represent a value and be evaluated again after edit?
thanks a lot!
Solved!

Hi,
I am assuming that you are trying to get a variable expression evaluated at runtime. I would do the following
Locals.Num=Val(Evaluate(SearchAndReplace("Locals.Var_X","X",Locals.Control_Num)))
All the variables are String and the output is a number on which you may perform further arithmetics.
You dodnt need the variable Locals.Var_X at all. I just created during my trials.

CallableStatement: how to get prepared call string?

How can I get the parameter string that is set via prepareCall() from a CallableStatement?
String call = "{call sp_irecord (?,?,?)}";
CallableStatement cs = connection.prepareCall(call);
//later, when 'call' is not known but cs:
String originalCall = csc.get???();
//how to get the call string from the callable statement?

i don't mean the parameter names or values, i mean the string that you set with the prepareCall() method:
String call = "{call sp_irecord (?,?,?)}";
CallableStatement cs = connection.prepareCall(call);
System.out.println("Call string: "+cs.getCallString());with the method getCallString() (that i invented and that i'm looking for) should return the exact string. The output of the example above should be:
Call string: {call sp_irecord (?,?,?)}

How to get the edit channel link from within the channel?

Following problem:
I want to include a link to edit the settings of a channel in the channel contents. The link should be the same as the edit button on the frame of the channel container. Searching through the provider jsps I found that the edit link is created in single.jsp. The code I need seems to boil down to
<dt:obtainContainer container="$JSPProvider">
<dtsingle:singleContainerProvider>
<dtpc:getStringProperty key="editContainerName" id="editContainerName" scope="request"/>
<dt:getName id="SingleContainer" scope="request"/>
<jx:declare id="editContainerName" type="java.lang.String"/>
<jx:declare id="SingleContainer" type="java.lang.String"/>
<dtsingle:obtainSelectedChannel>
<A HREF="<dtpc:getDesktopURL/>?action=edit
&provider=<%=editContainerName%>
&targetprovider=<dt:getName/>
&containerName=<%=SingleContainer%>"
TARGET="_self"> EDIT! </A>
</dtsingle:obtainSelectedChannel>
</dtsingle:singleContainerProvider>
</dt:obtainContainer>However I am unable to get that working in the channel, as I always receive a ProviderException on the line with
<dt:obtainContainer container="$JSPProvider">
What am I doing wrong, or is does the obtainContainer simply not work from within a channel?
If anyone can help me out to get the edit link it would be greatly appreciated. Any hints and/or sample code would help alot.
thanks!

How to get an XML string from a Java Bean without wrting to a file first ?

I know we can save a Java Bean to an XML file with XMLEncoder and then read it back with XMLDecoder.
But how can I get an XML string of a Java Bean without writing to a file first ?
For instance :
My_Class A_Class = new My_Class("a",1,2,"Z", ...);
String XML_String_Of_The_Class = an XML representation of A_Class ?
Of course I can save it to a file with XMLEncoder, and read it in using XMLDecoder, then delete the file, I wonder if it is possible to skip all that and get the XML string directly ?

I think so too, but I am trying to send the object to a servlet as shown below, since I don't know how to send an object to a servlet, I can only turn it into a string and reconstruct it back to an object on the server side after receiving it :
import java.io.*;
import java.net.*;
import java.util.*;
class Servlet_Message        // Send a message to an HTTP servlet. The protocol is a GET or POST request with a URLEncoded string holding the arguments sent as name=value pairs.
public static int GET=0;
public static int POST=1;
private URL servlet;
// the URL of the servlet to send messages to
public Servlet_Message(URL servlet) { this.servlet=servlet; }
public String sendMessage(Properties args) throws IOException { return sendMessage(args,POST); }
// Send the request. Return the input stream with the response if the request succeeds.
// @param args the arguments to send to the servlet
// @param method GET or POST
// @exception IOException if error sending request
// @return the response from the servlet to this message
public String sendMessage(Properties args,int method) throws IOException
    String Input_Line;
    StringBuffer Result_Buf=new StringBuffer();
    // Set this up any way you want -- POST can be used for all calls, but request headers
    // cannot be set in JDK 1.0.2 so the query string still must be used to pass arguments.
    if (method==GET)
      URL url=new URL(servlet.toExternalForm()+"?"+toEncodedString(args));
      BufferedReader in=new BufferedReader(new InputStreamReader(url.openStream()));
      while ((Input_Line=in.readLine()) != null) Result_Buf.append(Input_Line+"\n");
    else
      URLConnection conn=servlet.openConnection();
      conn.setDoInput(true);
      conn.setDoOutput(true);
      conn.setUseCaches(false);
      // Work around a Netscape bug
      conn.setRequestProperty("Content-Type","application/x-www-form-urlencoded");
      // POST the request data (html form encoded)
      DataOutputStream out=new DataOutputStream(conn.getOutputStream());
      if (args!=null && args.size()>0)
        out.writeBytes(toEncodedString(args));
//        System.out.println("ServletMessage args: "+args);
//        System.out.println("ServletMessage toEncString args: "+toEncodedString(args));
      BufferedReader in=new BufferedReader(new InputStreamReader(conn.getInputStream()));
      while ((Input_Line=in.readLine()) != null) Result_Buf.append(Input_Line+"\n");
      out.flush();
      out.close(); // ESSENTIAL for this to work!
    return Result_Buf.toString();               // Read the POST response data
// Encode the arguments in the property set as a URL-encoded string. Multiple name=value pairs are separated by ampersands.
// @return the URLEncoded string with name=value pairs
public String toEncodedString(Properties args)
    StringBuffer sb=new StringBuffer();
    if (args!=null)
      String sep="";
      Enumeration names=args.propertyNames();
      while (names.hasMoreElements())
        String name=(String)names.nextElement();
        try { sb.append(sep+URLEncoder.encode(name,"UTF-8")+"="+URLEncoder.encode(args.getProperty(name),"UTF-8")); }
//        try { sb.append(sep+URLEncoder.encode(name,"UTF-16")+"="+URLEncoder.encode(args.getProperty(name),"UTF-16")); }
        catch (UnsupportedEncodingException e) { System.out.println(e); }
        sep="&";
    return sb.toString();
}As shown above the servlet need to encode a string.
Now my question becomes :
<1> Is it possible to send an object to a servlet, if so how ? And at the receiving end how to get it back to an object ?
<2> If it can't be done, how can I be sure to encode the string in the right format to send it over to the servlet ?

How to get password as string back from encrypted password byte array.

Hi All,
I am storing encrypted password and enc key in the database.(Code included encryptPassword method for encryption and validatePassword method for validating of password). Problem is that for some reason i need to show user's password to the user as a string as he/she entered. But i am not able to convert the encrypted password from D/B to original String.
Tell me if any body know how to get the string password back from the encrypted password byte array after seeing my existing encryption code.
//********* Code
private Vector encryptPassword(byte[] arrPwd)
try
// parameter arrPwd is the password as entered by the user and to be encrypted.
byte[] encPwd = null;
byte[] key = null;
/* Generate a key pair */
KeyPairGenerator keyGen = KeyPairGenerator.getInstance("DSA", "SUN");
SecureRandom random = SecureRandom.getInstance("SHA1PRNG", "SUN");
keyGen.initialize(1024, random);
KeyPair pair = keyGen.generateKeyPair();
PrivateKey priv = pair.getPrivate();
PublicKey pub = pair.getPublic();
/* Create a Signature object and initialize it with the private key */
Signature dsa = Signature.getInstance("SHA1withDSA", "SUN");
dsa.initSign(priv);
/* Update and sign the data */
dsa.update(arrPwd, 0, 12);
/* Now that all the data to be signed has been read in, generate a signature for it */
encPwd = dsa.sign();
/* Now realSig has the signed password*/
key = pub.getEncoded();
Vector vtrPwd = new Vector(2);
vtrPwd.add(encPwd);
vtrPwd.add(key);
return vtrPwd;
catch (Exception e)
private boolean validatePassword(byte[] arrPwd,byte[] encPwd,byte[] key) throws RemoteException
try
// arrPwd is the byte array of password entered by user.
// encPwd is the encrypted password retreived from D/B
// key is the array of key through which the password was encrypted and stored.
X509EncodedKeySpec KeySpec = new X509EncodedKeySpec(key);
KeyFactory keyFactory = KeyFactory.getInstance("DSA", "SUN");
PublicKey pubKey = keyFactory.generatePublic(KeySpec);
/* Encrypt the user-entered password using the key*/
Signature sig = Signature.getInstance("SHA1withDSA", "SUN");
sig.initVerify(pubKey);
/* Update and sign the password*/
sig.update(arrPwd, 0, 12);
return sig.verify(encPwd);

Help upto any extent would be appreciated.

Hi All,
I am storing encrypted password and enc key in the
database.(Code included encryptPassword method for
encryption and validatePassword method for validating
of password). Problem is that for some reason i need
to show user's password to the user as a string as
he/she entered. But i am not able to convert the
encrypted password from D/B to original String.No, you are not encrypting the password in your code, you are merely signing it.
Tell me if any body know how to get the string
password back from the encrypted password byte array
after seeing my existing encryption code.It is impossible to retrieve the original text out of a signature.
You should read up on some encryption basics in order to understand the difference between signing and encrypting. Then you can find examples of how to encrypt something here: http://java.sun.com/j2se/1.4/docs/guide/security/jce/JCERefGuide.html.
Actually there is one class specifically for keeping keys secure, KeyStore http://java.sun.com/j2se/1.4/docs/api/java/security/KeyStore.html

How to get a global string value to be the value of a JSF output box?

im useing Jdeveloper 10 i have made a JSF, JSP page i have a backing bean for that page. in there i have made a global value:
private string test = "TESTING"these codes have been generated:
public void setTester(HtmlOutputText outputText6) {
this.tester = outputText6;
public HtmlOutputText getTester() {
return tester;
}now how do i put test as the output text?

That wouldn't even compile. HtmlOutputText isn't a subclass of String (heck, java.lang.String is a final class).
Two ways to solve this: 1) use HtmlOutputText#setValue() in the constructor or initialization block of the bean or even by lazy loading in the getter. Just create a String getter and use it in the value attribute of the outputText element in the JSF page.

How to get an xml string into a Document w/o escaping mark-up characters?

Hi,
I am using one of the latest xerces using Java. I am pretty sure I am using xerces-2.
I have an existing Document and I am trying to add more content to it. The new content itself is xml string. I am trying to insert this xml string into the document using document.createTextNode. I am able to insert, but somewhere it is escaping the mark-up characters (<,>,etc). When I convert the document into String, I can see, for example, <userData> instead of <userData>.
There is an alternative option to accomplish this by creating a new document with this xml string, get the root element, import this element into my document. Execution time for this procedure is very high - means, this is very bad in terms of time-wise performance.
Can any help on how to accomplish this (bringing an xml string into a document without escaping mark-up characters) in time-efficient way.

So you want to treat the contents of the string as XML rather than as text? Then you have to parse it.
Or if your reason for asking is just that you don't like the look of escaped text, then use a CDATA section to contain the text.

How to get InputStream from String ?

Hi !
I want to get InputStream object from String.
String str = "balabalabala";
InputStream stream = getInputStream(str);
How to realize getInputStream(str) function ?
Thanks!

The preferred method nowadays is to use Readers and Writers for String data - hence StringReader(String). If you're going to operate on the InputStream directly, then I'd modify your code to use the Reader calls and go that route.
If, however, you need to pass the InputStream to some other piece of API that requires an InputStream instead of a Reader, then the ByteArrayInputStream is probably your best bet. StringBufferInputStream is deprecated because it doesn't work reliably in the face of many character encodings.
Speaking of encodings - never call Strng.getBytes() - always use the getBytes(character-encoding) version, so you KNOW what encoding you're getting!
