Getting compilation error: java.util.Set is an interface. This interface is not supported.

Hi Folks,
Is there a limitation in BEA's web services implementation? I have a simple web
service that returns an array of java objects. However I am calling another middle
tier API that returns a Set. I convert this Set into array of object and return
it via the web service.
However the .jws file that implements the webservice does not compile. I get the
following error message:
java.util.Set is an interface. This interface is not supported.
Is there a limitation on using Collections within the .jws file? If that is the
case it is a severe limitation.
Note my Web Service API returns an array of java objects with no collections in
them.

Hello,
Generic java collections can only be handled in a very generic, weakly
typed manner.
Take a look at the
http://workshop.bea.com/xmlbeans/guide/conXMLBeansSupportBuiltInSchemaTypes.html
and also
http://workshop.bea.com/xmlbeans/guide/conJavaTypesGeneratedFromUserDerived.html
You might also ask your question to the XMLBeans newsgroup:

ADF Faces af:table support java.util.Set

I was using a java.util.Set in my model classes, as implementation of the Collection interface. And wanted to show the Set using a <af:table> after a while I discoverded that the documentation did not mention support of java.util.Set, only List.
Now I have to convert my collection to List in the backing beans of my view.
Is there a better approch than converting every Set in the view using
new Arraylist(set)?
And what is the reason of the missing Set support (or General Colelction support)?
Thank you

Deepak, I don't think you know what you're writing about.
No, we do not support java.util.Set in <af:table>. For that matter, neither does <h:dataTable>.
The "why" of it is that we require indexed access into the table for operations like "Display rows 526-550". java.util.Set does not offer indexed access.
By the way, one corollary - do not use java.util.LinkedList with tables (ADF Faces or the JSF data table). If the list is small, then it won't be a problem, but with a large list, you'll get brutal performance.

Can't create log file with java.util.logging

Hi,
I have created a class to create a log file with java.util.logging
This class works correctly as standalone (without jdev/weblogic)
import java.io.IOException;
import java.text.DateFormat;
import java.text.SimpleDateFormat;
import java.util.Date;
import java.util.logging.*;
public class LogDemo
     private static final Logger logger = Logger.getLogger( "Logging" );
     public static void main( String[] args ) throws IOException
         Date date = new Date();
         DateFormat dateFormat = new SimpleDateFormat("yyyyMMdd");
         String dateStr = dateFormat.format(date);
         String logFileName = dateStr + "SEC" + ".log";
         Handler fh;
         try
           fh = new FileHandler(logFileName);
           //fh.setFormatter(new XMLFormatter());
           fh.setFormatter(new SimpleFormatter());
           logger.addHandler(fh);
           logger.setLevel(Level.ALL);
           logger.log(Level.INFO, "Initialization log");
           // force a bug
           ((Object)null).toString();
         catch (IOException e)
              logger.log( Level.WARNING, e.getMessage(), e );
         catch (Exception e)
              logger.log( Level.WARNING, "Exception", e);
}But when I use this class...
import java.io.File;
import java.io.IOException;
import java.text.DateFormat;
import java.text.SimpleDateFormat;
import java.util.Date;
import java.util.logging.FileHandler;
import java.util.logging.Handler;

    String dateStr = dateFormat.format(date);
    String logFileName = dateStr + ApplicationName + ".log";
    Handler fh;
    try

      logger.setLevel(Level.ALL);
      logger.log(Level.INFO, "Initialization log");
    catch (IOException e)
      System.out.println(e.getMessage());
}and I call it in a backingBean, I have the message in console but the log file is not created.
TraceUtils.initLogger("SEC");why?
Thanks for your help.

I have uncommented this line in logging.properties and it works.
# To also add the FileHandler, use the following line instead.
handlers= java.util.logging.FileHandler, java.util.logging.ConsoleHandlerBut I have another problem:
jdev ignore the parameters of the FileHandler method .
And it creates a general log file with anothers log files created each time I call the method logp.
So I play with these parameters
fh = new FileHandler(logFileName,true);
fh = new FileHandler(logFileName,0,1,true);
fh = new FileHandler(logFileName,10000000,1,true);without succes.
I want only one log file, how to do that?

Puzzled by the redefinition of the methods in java.util.Set

Hi all,
I don't understand why those methods in java.util.Set redefined since their counterparts have alrealdy been defined in java.util.Collection and java.util.Set extends java.util.Collection. I agree to redefine boolean add(Object o) because its contract has been modified, but what about the rest like
size() and iterator() ?
Thanks.

Help with java.util.Random

Problem:
I wanna generate random number in interval <0;1> with two "decimal number precision" (i dont know, how to expres it exactly in English.. So, here is Patern: "*X.XX*" (For ex. it might be numbers like 0.24 , 1.00 , 0.05, 0.54) ).
I have tried to work with java.util.Random class, but i dont understood it at all, because i'm not good in Math-English terms.
So, how can I do it? I offer duke stars for any solve. Thanks.

First of all, read this link to understand why all floating point numbers (float, double) can't be rounded to two places of decimals.
[What Every Computer Scientist Should Know About Floating-Point Arithmetic|http://docs.sun.com/source/806-3568/ncg_goldberg.html]
Consider changing your program to use integer numbers in the range of [0..100] instead. You can generate a random number in this range byRandom random = new Random();
int randomInt = random.nextInt(101);If your problem can't be solved with this approach, you may need to tell us exactly how you plan to further process the random number.

How do I compress a string with java.util.zip - not a file ?

How do I compress a string with java.util.zip?
Is possible to compress something else except a file?

Of course, compression works on bytes, not some higher level constructs like Strings or files.
You can use the ZipOutputStream or DeflaterOutputStream for compression.
And the javadoc for Deflater even has a code example of compressing a String.

I've created my own dictionary with dateToSQL() method overridden.
Now it works fine. But it's a kind of strange. Oracle is used often and my
JDBC drivers
are the most recent (at least, from the oracle.com).
Anyway, thank you again.

Patric,
Thank you for response.
We're using Oracle 8.1.7 via OCI driver from Oracle 9.2.
I've already tried 2.4.0 and it works fine there but I've found another
problem there
preventing me from using it. See my post in solarmetric.kodo.betanewsgroup.

That's odd -- what version of Oracle are you using?
Moving to Kodo JDO 2.4.0
(http://www.solarmetric.com/Software/beta/2.4.0) will almost certainly
get rid of this problem, as we use exclusively prepared statements in
it, and therefore pass dates etc. to JDBC as parameters.
But, to get things working with your Oracle database and Kodo JDO 2.3,
you could create your own extension of OracleDictionary and override the
dateToSQL() method to generate the appropriate TO_DATE() syntax. See our
documentation for more details on creating custom database dictionaries.

What's wrong with java.util.Date??

Hi all,
I was just practicing a bit of java.util ,when i was compiling my code-
import java.util.Date;
import java.text.SimpleDateFormat;
class DateStamp{
public static void Main(String args[]){
doDate1;
String D;
int D1,D2,D3;
Date dt=new Date();
SimpleDateFormat sdf=new SimpleDateFormat("dd-mm-yyyy");
/*When using method .setDate(x) ,is x an integer or String?can x=2/5/2002 or 2-5-2002?*/
public void doDate1{
dt.setDay(12);
dt.setMonth(12);
dt.setYear(102);
D=dt.getTime();
D.parseInt(D1);D=""
D=sdf.getTime();
D.parseInt(D2);
int D3=D2-D1;
int D3=D3/86400000;/*How do you convert milisec-to-days?*/
D=D3.toString().
System.out.println(D+"days have elapsed since then");
the compiler said this-
File Compiled...
--------------------------- Javac Output ---------------------------
DateStamp.java:7: Invalid expression statement.doDate1;^DateStamp.java:14: Instance variables can't be void: doDate1public void doDate1; ^2 errors
this problem is persistant, and i'm a java newbie ,Does anyone know what's wrong here?

How do you get System date onto a Date variable?Calendar.getInstance().getTime() returns a java.util.Date for the current time. You can also use System.currentTimeMillis() and turn it into a Date.
Will date.after(Date when) method work when Date
variables are in milisecs?Date.after(Date when) compares two date objects. As the JavaDoc says "Returns:
true if and only if the instant represented by this Date object is strictly later than the instant represented by when" To me that says that milliseconds are taken into account, I.E. comparing dates actually compares the date plus the time portion.
>
What methods-
*Convert a date(dd/mm/yy) to milisec?If you look in the javaDoc you'll see "long getTime() Returns the number of milliseconds since January 1, 1970, 00:00:00 GMT represented by this Date object." Calendar also has the getTimeInMillis() method.
*Convert a milisec value to a date(dd/mm/yy)?Calendar.setTimeInMillis(long);
I'm have this little problem.
When using GregorianCalander-
*need to initialize?
*need set today's date?Calendar.getInstance() will return an appropriate Calendar object for the current locale initialized to the current date/time.
*how do you check if a date exceeds 3 weeks?I'm not sure what you mean. There are a couple of roll(...) methods that will allow you to add a unit of time to a date. I.E. you could add three weeks to a date.
To ignore the time portion of a date just set the time to "00:00"

Who use sql-mapping with java.util.regex?

Hi everyone:
I use the IBatis SQL-Mapping and I think it is very good.Now I want to add the search function to my BBS forum.I also want to display the content high light like jive.I mean that if I want to find the string "ibatis",then the search result "ibatis" will be high light displayed.
So I must use the java.util.regex in jsdk1.4.But the problem is that what I get is a List if I use sql-mapping.For example:
          String resource="conf/XML/sql/lyo-sql-map.xml";
          Reader reader=Resources.getResourceAsReader(resource);
          sqlmap=XmlSqlMapBuilder.buildSqlMap(reader);
          List articlelist=sqlmap.executeQueryForList("selectSiteArticle","%"+icontent+"%");
The result I get is a List and I have no time to use regex.
I don't know whether I could do this:
Iterate the List,use the regex and later place all the object back to the List.
It's right?
How to use regex with sql-mapping?Thks

Getting error by ValueBinding with java.util.Date

Hi.
1. my english is not so good.
I develop a JSF-application to learn more about JSF-technologie.
I use Eclipse 3.2
Plugins: Web Tools Platform (WTP), Web Standard Tools, Java Server Faces // Version 1.5.0
JRE: 1.5
java-impl.jar and java-api.jar (sun)
Look at this JSP-File Code
<h:inputText id="dbirth" value="#{dataBean.dbrith}"> </h:inputText>
this produce an error: EL expression does not evaluate to expected types for this attribute
dataBean is a ManagedBeain. So if I use any athor variable from this Bean like:
<h:inputText id="sname" value="#{dataBean.sname}"> </h:inputText>
is going well. But if I use any java.util.Date variable it produce the error.
I tried with other Bean and the error is still there.
I can compile and use this JSP, but this error is there.
Have any one an idea what is happen there??
I looked at Eclipse forums, but I didnt found description for an error like this..
thanks for any help...

The problem is because you have bound the inputText to a java.util.Date object, instead of a String. You must use Strings with inputText. However, JSF has provided a way for you to convert objects into a String. It just needs to know how to do that. Luckily for you, there is a converter already available to convert a Date object into a String. Converters will also take input Strings and convert them into an object.
So, in your case, use the convertDateTime tag. Like this:
<h:inputText id="dbirth" value=#{dataBean.dbrith}">
<f:convertDateTime type="date" pattern="MMM dd, yyyy" />
</h:outputText>Try it. You may change the pattern to whichever valid one you like.

Tried~
The problem is still here~ >___<
Anyway, thanks for information sharing~
The message is:
Cannot open file: it does not appear to be a valid archive.
If you downloaded this file, try downloading the file again.
The problem may be here:
if (fos != null)
fos.close() ;
if (bos != null)
bos.close();
if (zos != null)
zos.close();
if (file != null)
file = null ;
The fos is closed before bos so the last buffer is not
saved.
zos.close() is enough.

             ServerSocket welcomeSocket = new ServerSocket(5050);
             while(true) {
                Socket connectionSocket = welcomeSocket.accept();
                BufferedReader inFromClient = new BufferedReader(new InputStreamReader(connectionSocket.getInputStream()));
                while ((clientSentence = inFromClient.readLine()) != null) {
                     System.out.println("Received: " + clientSentence);
             }And I have a java.util.logging logger using a SocketHandler. I'm just calling logger.log("my message"); I get the expected result to System.out: "my message". But when I go on to call again logger.log("my next message") I get both messages in queue: "my message" and "my next message" on the next line. So, I get from these two calls to logger.log() the following result in System.out
my message
my message
my next message...whereas I expected
my message
my next messageWhy is "my message" being saved even after being passed through the TCP connection to the server? I tried handler.flush() but that doesn't help. Pretty sure the problem isn't at the server end because when I create two loggers with their own SocketHandlers the server doesn't double up on their messages. (In other words, if I let one logger say simply "my message" and the second logger say "my next message" I get the expected output. It's like each logger needs to be flushed after sending to the server.
Any advice appreciated.

Yes, I was just rereading your post and it's apparent that you were suspecting the client code. Your posting only the server led me to believe that you were focusing on that and I kind of skipped over the last part.
So to answer your question, yes, the server code looks okay. And you were suspecting the client anyway, so problem solved.

Multi currency support with java.util.Locale

My project has a requirement to support multiple currencies as our first internationalization feature. However, I've come across something with the Locale class that doesn't really make sense to me, and I'm wondering if anyone else has any best practices or insight.
Why can't you create a Locale knowing only the ISO 3166 code? For multi-currency support, it doesn't make sense that I should need to provide a language in order to obtain a Locale, which is needed to generate the proper NumberFormat (and in 1.4 the java.util.Currency) class.
Is there an instance where the language one speaks is directly correlated to the currency that they use?
Actually, it doesn't make much sense that you can create a Locale only from a language either, since if my user a Hispanic-American, the language would be Spanish but the country (and therefore currency) would be US.
It seems to me that if the Locale class can default a country code based on the language, it should also be able to default a language based on the country.
Given these limitations, is there a recommended best practice about obtaining a Locale without a pre-determined language?

Hi,
this was a bit of a bugbear for a long time. Currency kind of wound up inexorably linked to Locale for a long time because the way a currency was formatted depended on the textual layout of the language as well as the country, and as date formatting was an issue too, it was easier for them to implement it the way they did.
It's been an RFE for a long time, and I believe the beta releases of Merlin carry a currency API that is separate from a Locale. The link to the RFE is below. Hopefully Merlin Beta will allow you to achieve what you want - it seems to be pretty stable from what I've seen of it, and Sun do have a good record when it comes to releasing stable betas, so I wouldn't panic too much about the fact you're developing on a "pre-release candidate" JDK.

Hope that helps!
