Java viewObject.getOrderByClause question

I have set an ORDER BY clause in my bc4j view object. I want to replace it with a different ORDER BY clause.
However, when I do retrieval of the ORDER BY clause from the view object such as:
String oldOrderByClause = (String) vobj.getOrderByClause();
it comes back as null.
If I retrieve the whole query from the view object:
String oldQuery = (String) vobj.getQuery();
The whole sql statement including the ORDER BY clause is there.
The same thing is true of the where clause also.
Does someone know how this is supposed to work?
Thanks, Steve

I just completed some research and noted that, in my java program, if I set the order by clause and execute the query, before I return to my uix screen, I can retrieve the order clause I just set.
However, when I re-enter that uix page, and re-execute the code to set the order by clause, the order by clause I just set is gone, and the retrieval is back to null.
Is there anyway for this change to persist in the view object?
Thanks, Steve

WD Java iView Creation Question/Issue - CE 7.1 EHP 1 Trial

Hi all,
Im posting this question here seeing as that the issue has arrised on an installation of the AS JAVA and EP shipped with CE 7.1 EHP1 Trial.
When attempting to create an iView for a deployed custom WD Java app on the trial Portal I am taken straight to the iView template selection without being given the options for iView creation( ie. create from template, portal component or WD Java app). Is this by design ( WD Java iView creation has changed from previous Portal versions or is limited in Trial installation), is this an issue with the components shipped with the Trial or an issue on my installation only?
Currently my only solution for deploying WD java content is to copy the actual application and paste it as Portal content which then creates a WD Proxy page with a single WD Proxy iView (that of the copy pasted WD app). This is fine for single app scenarios but becomes an issue with multiple apps on one page and drag and relate scenarios.
Kind regards,
Willem.

Java reflection (interesting question)

hi folks,
class A {
void foo() {
Class B overrides method foo() in A
class B extends A {
void foo() {
Now i create a object of class B and assign to A
A aref = new B();
aref.foo() will call method foo()of class B. //polymorphism
Using reflection, is it possible to call method foo() of class A using the handle aref.
thanks
venkat

hi bondvenky,
What abt the answer for my original question. How to
access the base class methods using the handle for
child class object using reflection ?as far as i know, this isn't possible - your next question is probably going to be "why". It certainly seems slightly surprising that you can't do this, but you can access private methods. Unless you consider the latter a weaker way of breaking encapsulation (!?).
what was the sun's purpose behind allowing access to
the private methods of an object using Java
Reflection? good question.. its very useful but on the other hand i can't think of a time i've used it that couldn't be classed as a hack.
Is it not a security threat to java security model?it doesn't break anything - ie its not a security loophole. It links in with your question above though - would it have been possible/useful to not allow it period?
sorry for the vague answers :(

Java/OO Design question. Please help!

Brian,
I'd say your better off trying the
weblogic.developer.interest.ejb newsgroup
or alternatively try the discussion forums in
www.theserverside.com
or
http://forum.java.sun.com/
For what its worth I'd return an empty array rather than an exception as I associate
exceptions with real errors whereas a search that happens to return nothing is a
valid result.
Cheers,

I'm certain this is not the best forum for my question, but I didn't any

I have a design issue/ OO question. Our system has the very common requirement
of searching. We have build a session EJB which actually performs the search
and returns a collection of Value Objects back to the client. My question
is
this: If the search EJB finds no matching records, what is the correct
strategy
for dealing with it?
1) Throw an application exception, such as "NoDataFound", which the client
can
catch and handle appropriately
2) Simply return a null collection. In which case, the client will have
to check
for null, and redirect program appropriately.
3) Simple return type, such as boolean, for the method -- indicating success
or
failure (meaning no records found).
4) Something entirely different. If so, what?
Your thoughts on this subject would be greatly appreciated!
Thanks!

AutoVue for Agile PQM - Java Runtime Environment Question

Greetings,
An end user is attempting to view/open attachments within Agile Product Quality Management (PQM); we use Agile PQM 9.3.1.
When clicking on an attachment file, a pop-up screen opens with a javascript alert, prompting the user with, "Please Install Java Runtime Environment." After clicking "OK", user is redirected to java download website. User downloads and installs the update.
After rebooting the machine, we attempt to access the attachment file again within PQM and receive the same error message, "Please Install Java..."
After installing the first java update, the user is now on the following java version:
Java Plug-in 10.55.2.14
Using JRE version 1.7.0_55-b14 Java HotSpot(TM) Client VM
Do we need to install the second update to be able to view attachments within Agile PQM via AutoVue?
I can't test the java updates myself because there are some legacy Oracle apps that I won't be able to support if I update my java.
Thanks in advance,
William

You might want to post the question to the Agile forum
The popup you see seems to be tied to Agile code itself and not AutoVue
AutoVue will work on Java 7u55
But you are running Agile, so you will need to make sure the rest of the apps are confirmed with 7u55
You also need to review Java update guidelines, by default you will be always prompted to install the latest java update

Java Usage Concept Questions

I have a java Command line running program. Which allow input/edit data of clients and store them into a Flat file. The problem is that i have to make a GUI, ( a thin web based client ) and using only HTML and Javascript.
The next step is the db should be frontended by servlet or JSP that interact with thin client to perform the database retrievals.
Now my concept Questions:
1. Is it possible to communicate to a Java Program using HTML and Javascript? If so, any exampler, pointers?
2. I was thinking of using HTML and Javascript to directly modify the Database. ( Since it is a flat file therefore nothing more than a txt file ) But isn't this side stepping the problem?
3. If i could modify the Flat file using HTML and Javascript only. Why would i need JSP and Servlets? And if i could do it with JSP and Servlets only why would i need the think client ( HTML bit )?
If all of above 3 are correct ( conceptialy ), what is the orginal command line java program for?
The last question is why i think i have the concept wrong. Please i am new to web programming so feel free to point out any error.

Hello,
You a little off on a few things. let me explain what each is used for to give you a better idea what each i used for.
HTML - Used to format data. Is static and can't do any File I/O and such
Javascript - Is usaually used for client side validation and some cool effects.
JSP - Is a scripting language that allows you to execute code on the server to create dynamic content and server side stuff like saving to a DB or a file
Servlets - Kinda like JSP but gives you more control over a few things. Usaually used for form processing and Servlet/Applet communication
for you application i would probably embed HTML/JavaScript for layout and validation into a JSP page for your display pages.. then build JSP pages to handle all you business logic and processing.

"Can you list me some features of the java language"(Interview question )

Hi,
This was a question I got yesterday in an interview, exactly as the interviewer said it.
I listed off it's cross platform feature... what else would you have added?
Question 2. He also looked for #2the differences between java and C++"

It does if you put <sarcasm> tags in/Too easy, and that wasn't the point back then anyway. :)
Look at this forum sometime and see how many people
cram procedural code into a main and still call
themselves "Java programmers". Yepp. I dare to say that I do much better design, yet I don't call myself a programmer, even though I get paid for coding.
Java doesn't enforce
it, either. There's no way to mandate O-O thought.Yes and no. IIRC (it's been a very long time, and I mostly did C, anyway), you can write C++ code without ever creating one class. You can't do that in Java. So It's be a bad OOD, but never a good structural design, as structural design doesn't know classes.

Java.lang.ExceptionInInitializerError question

Having a problem with Java Cryptography Extension (JCE)
Author: dnhll23 Jul 6, 2002 2:11 AM
Hi, this is my first attempt at using the JCE. I'm using JCE 1.2.1
and basically all I'm trying to do at this point is encrypt a
FileInputStream object using the DES standard, with the JCE
classes. Here is my code Fragment.
protected FileOutputStream encriptFile(FileInputStream baseFile,
File encFileName) throws IOException
try
// Create the output file for the encrypted document
FileOutputStream encriptedFile = new FileOutputStream
(encFileName);
// Must register the provider that implements the algorithm
Provider sunJce = new com.sun.crypto.provider.SunJCE();
Security.addProvider(sunJce);
char[] pbeKeyData = password.toCharArray();
PBEKeySpec pbeKeySpec = new PBEKeySpec(pbeKeyData);
SecretKeyFactory keyFactory = SecretKeyFactory.getInstance
("DES");
SecretKey pbeKey = keyFactory.generateSecret(pbeKeySpec);
Cipher pbe = Cipher.getInstance("DES"); // Same as above.
pbe.init(Cipher.ENCRYPT_MODE, pbeKey);
CipherOutputStream cout = new CipherOutputStream
(encriptedFile, pbe);
// Use a byte array to write the file output in blocks of 64
bytes.
byte[] buffer = new byte[64];
while (true)
int bytesRead = -1;
bytesRead = baseFile.read(buffer);
if (bytesRead == -1) break;
cout.write(buffer, 0, bytesRead);
cout.flush();
cout.close();
baseFile.close(); // Close the input file.
catch (java.security.NoSuchAlgorithmException nsA)
System.err.println(nsA);
nsA.printStackTrace();
catch (java.lang.ExceptionInInitializerError eIIE)
System.err.println(eIIE);
eIIE.printStackTrace();
catch (Exception e)
System.err.println(e);
e.printStackTrace();
My problem arises with the line "SecretKeyFactory keyFactory =
SecretKeyFactory.getInstance("DES");" This line throws an
ExceptionInInitializerError and the catch block tells me this
java.lang.ExceptionInInitializerError
java.lang.ExceptionInInitializerError: java.lang.SecurityException:
Cannot set up certs for trusted CAs
(The rst of the stackCall here)...
From what I've read in the documentation, I need to have a provider
set up that handles the SecretKeyFactory and encryption algorithms,
but the documentation also says that the SunJCE provider that I set
up near the start of my method should have been able to handle this.
Is there anyone out there with expeience doing this kind of thing
that can help.
Thanks

Have you figured out an answer to this problem yet? I'm having a very similar problem. I'm running an applet that needs to decrypt information that it is retrieving from CORBA and I'm getting the following exception:
java.lang.ExceptionInInitializerError
at javax.crypto.Cipher.getInstance(DashoA6275)
at CorbaDecrypt.doDecryption(CorbaDecrypt.java:132)
at EventChannelListener.run(EventChannelListener.java:325)
Caused by: java.lang.SecurityException: Cannot set up certs for trusted CAs: java.lang.SecurityException: Cannot verify jar:file:C:/PROGRA~1/Java/J2RE14~1.0_0/lib/security/local_policy.jar!/
at javax.crypto.SunJCE_b.<clinit>(DashoA6275)
... 3 more
I'm using JDK 1.4 so, there's no need for my code to have the two Provider setup lines, but otherwise my code looks much the same as yours. The code works fine when run in a test app on the server, but not in the Applet. The file that it's looking to verify (local_policy.jar) does not exist, and I don't want to create one manually, because my users would have to do that then too, which is unacceptable. I am using a trusted applet, so I'm not sure what more I can do to grant the applet the proper permissions. Does anyone have any ideas what we need to do here?
Thanks.

I've followed all the instructions for installation and configuration in the JCE User's Guide.
Any suggestions?

Java.util.logging question

'Lo all -
I'm new to Java, so bear with me on this question - I'm sure it has a simple answer.
I am using the following code to create a new Logger object:
public class TAGLogging {
    private Logger oLog;
    private FileHandler oLogFile;
    private String sLoggingFolder = "AppLogs";
    private String sFormattedDateTime = String.format("%1$tY%1$tm%1$td_%1$tH%1$tM%1$tS",Calendar.getInstance());
    private String sCallingClass = new Throwable().fillInStackTrace().getStackTrace()[1].getClassName();
    private String sCallingMethod = new Throwable().fillInStackTrace().getStackTrace()[1].getMethodName();
    /** Constructors */
    public TAGLogging(String sLogFileName) throws IOException {
        this.initialSetup(sLogFileName);
    public TAGLogging() throws IOException {
        String sLogFileName = sLoggingFolder + File.separator + sFormattedDateTime + ".xml";
        this.initialSetup(sLogFileName);
    /** Methods */
    private void initialSetup(String logFileName) throws IOException {
        oLogFile = new FileHandler(logFileName);
        oLog = Logger.getLogger(sCallingClass);
        oLog.addHandler(oLogFile);
        oLog.setLevel(Level.ALL);
    }Everything is being logged correctly to the /AppLogs/yyyymmdd_HHMMSS.xml file. The problem is that there is another file that is being created in my home directory, which incidentally, is not where the program is located. The name, java01.log, matches the default logging.properties file set up, but I have removed all that and changed the file to the following (minus all the comments):
handlers= java.util.logging.FileHandler
.level= INFO
java.util.logging.FileHandler.level = ALL
java.util.logging.FileHandler.limit = 50000
java.util.logging.FileHandler.count = 1
java.util.logging.FileHandler.formatter = java.util.logging.XMLFormatter
java.util.logging.ConsoleHandler.level = INFO
java.util.logging.ConsoleHandler.formatter = java.util.logging.SimpleFormatter
The java01.log file contains the exact same contents as the file I am purposely logging to, the AppLogs/yyyymmd_HHMMSS.xml one.
Does anyone have any clue what is causing this file to get created, and if so, how do I stop it?

Man, I REALLY hate to do this, but it looks like I may be forced to work around it instead of fixing the issue. I'll have to add some code to manually remove the java01.log file when it's done writing to it.
Navy - Turns out that Log4j is pretty much the same thing as java.util.logging, except on steroids. It is almost identical syntactically, just has more options and more flexibility than JUL.

Four Java Applet signing questions

hi all;
I'd like to ask a few quick questions about applet signing. As you know there is a "Security Warning" Gray Alert box that appears when the user tries to load your signed applet.
1. When the alert window asks someone to accept the signed applet, is it possible to some how capture the Yes or No button click event by javascript or something like that ? I noticed that the Yes and No Response seems to be saved in an in-memory cookie? Is it possible to figure out wht the person clicked ?
2. Is it possible to keep that "Security Warning" Alert box on top so that the user will not be able to accidentally ignore it (it goes under the browser and stays there).
3. Is there some way to inspect the PC to determine weather your applet loaded properly - apart from seeing a properly working applet ? For example , If I want to make sure it is being cached properly.
4. When a new version of the applet is available on the server ? how does the browser know to download something ? is that something I would code for manually or would is this automatically handled behind the scenes.
Thanks in advance

Java Developer Exam Questions

I got my JCP certification a while ago and have been debating if it is even worth it to go forth and get the Developer certification. A colleague of mine told me that certification exams for specific technologies are generally good only for contract work, not for full-time employees. He suggested rather than wasting my time and money on exams that I should take night classes and work towards a masters.
So this is really a two part question, first of all do you think it is worth the money and time? Secondly, what kind of project assignment could I expect to get if I sign up for it?

well certification in itself is a buzzword which
might be missing.No one expects a developer with 10 years of
experience to have a developer certification in the
CV. It might actually make the CV look odd /
suspicious. Why have a developer certification in
there if you already have lots of experience?
KajWell I have personally interviewed 10s of developers with 10 years of experience, but actually it turned out that they had 10 * 1year experience. Certifications are just a proff that you have worked on that technology as well. We are not talking about just java certifications. e.g. if I am hiring a java developer with 10 years of java experience who has an oracle certification as well, and I need somebody in the team to have a good understanding of databases it would be beneficial.
Or if the job requires some level of tibco experience, tibco certification would be good to have. Certifications just serve a hint that the applicant has some level of proficiency in the field he has been certified in. A j2ee enterprise architect certification might give one an idea that the applicant is familar with some practices in enterprise architecture. 10 years experience might not guarantee that, plus you might agree a lot of resumes you see these days of mid level developers, claim some kind of architectural exp., thought they might not even know of GoF patterns let alone Enterprise integration patterns. If I have two resumes in front of me with same amount of experience, one with a lot of certifications and the other just experience I would prefer the former, since atleast i know somebody has already done the pre screening for me.
I know what you are talking about, but I always encourage developers to go for certifications and not just java certifications,.
PS. I am not talking about entry level certifications only.
