Econometrics/Statistical computaion with Java - Need advice

Dear All,
I need to perform econometrics/statistical computaion for the bank. We were using Matlab from MathWorks.com. Recently, we are planning to perform computation with java instead of Matlab.
e.g. below is the sample equation that I want to evaluate in java -
∆Φ_^(-1) (SDP_t )_ =B_1 〖∆SDF〗_(t-1 )+ B_2 〖∆XXX〗_(t-2 ) + B_3 〖∆linear〗_(t-1)+B_4 〖∆Linear〗_(t-2)
+Z_m
My question is, I have not found API in java though which I can perform calculation. Also, we are performing this type of computation first time in java, does java supports all statistics calculation like standard deviation, mean distribution et cetera.
I came across Apache commons-maths library which provides class related to maths/statistics. (http://commons.apache.org/math/api-1.2/index.html)
Has anyone performed statistics/equation evaluation in java or with Apache commons-maths? Please share your thought?
I appreciate your time reading my post.

the concept of mean distribution must be sth in econometrics that hasn't caught on.
Java math does not define standard deviation or any other stat methods. it's quite easy to program though. to do linear algebra and optimization you will need to call C or Fortran libraries from java. no need to reinvent the wheel.

New to java needs advice

Hi,
I'm completely new to java and after a few days search found Studio Creator and decided to use it. Happily developing for a week in JSC, I reached the deployment to Tomcat stage.
Mybe I'm missing something but I find this stage ruining the ease-of-use feeling which I got when I started using JSC.
Am I right that JSC doesn't have a built-in functionality to deploy to Tomcat whithout my intervention, considering my total unfamiliarity with xml, jsp, mysql, etc.?
If so do you guys know of another easy-to-use IDE like JSC?
Any pointers are greatly appreciated.
Thanks, Abraham

Parsing XML with Java - seeking advice for method to pursue

Hi guys
So here's the deal: I want to parse some XML from a server, get all the data I need from it, then shunt that data to the classes that need it. However, I'm really not sure what the best way of parsing the XML is.
I've just written a class for obtaining the file, and one for building a DOM from the XML file. But looking at org.w3c.dom in the Java API documentation (see HERE) I'll have to implement shedloads of interfaces to be able to take advantage of the DOM, and I don't even know a lot about it.
So am I best just writing a simple parser based on regular expressions to get the data I want? There's about 5 attributes in the XML file that I need to get - 5 for each instance of the containing element. So I don't think it'll be hard to do with regular expressions.. plus even if I did decide to implement all the DOM interfaces, the only way I'd know how to do half the stuff is with regular expressions anyway. I mean, how else would you do it? How else could you match up Nodes according to the Strings you're using for the elements, attributes etc?
I worry that a parser using regular expressions might be too slow... I'm building this as an applet to visually display information from the server. I have nothing to support those fears, I'm just not experienced enough to know whether speed would be a problem if I chose this route... I don't think it would, but really need confirmation of that suspicion being unfounded.
Any advice would be very, very welcome, as I'm tearing my hair out at the moment, unsure what to do.

Komodo wrote:But JDOM is not in the core class libraries, is it? So if I want to create an applet embedded into a website, am I able to get people to download that as well?
Sorry, I don't know anything about applets.
Komodo wrote:Everyone's advice is appreciated, but my core question remains unanswered - would using regular expressions, considering how simple and unchanging the XML files are, be a viable option in terms of speed?
Yes! I've done more than my fair share of XML processing with REs. It's not always easy. I often wish I could just use something XPath-like. But it's certainly easy to do and would probably mean that you'd have something up and running quicker than if you spent time investigating pure XML parsing approaches.

WITH CLAUSES - need advice

Recently we found that the server converts all the request to 'with clauses' format in the physical query even if the request does not contain any subquery. I am bit concerned on this as some article suggest that there is a limitation in using with clauses and it can return unexpected results. Could this change in behavior cause some problem?

Hi all,
We are currently using ORACLE 10g.
For ex the original query for a specific report would look like
select distinct D1.c1 as c1,
D1.c2 as c2
from
(select distinct T41994.NAME as c1,
T41994.LOC as c2
from
(SELECT
A.*,
ORA62102.F_UTC2LOCAL(A.CREATED_TS,'(GMT-08:00) Pacific Time (US & Canada); Tijuana') AS CREATED_LCL,
ORA62102.F_UTC2LOCAL(A.LAST_UPD,'(GMT-08:00) Pacific Time (US & Canada); Tijuana') AS LAST_UPD_LCL,
ORA62102.F_UTC2LOCAL(A.REFERENCE_START_DT,'(GMT-08:00) Pacific Time (US & Canada); Tijuana') AS REFERENCE_START_DT_LCL,
ORA62102.F_UTC2LOCAL(A.INDEXED_DATE_0,'(GMT-08:00) Pacific Time (US & Canada); Tijuana') AS INDEXED_DATE_0_LCL
FROM ORA62102.S_ORG_EXT A) T41994
where ( T41994.BU_ID = '1-D3DGK' and T41994.DELETED_STATE = 'N' )
) D1
Now the query is changed to the following format
WITH
SAWITH0 AS (select distinct T41994.NAME as c1,
T41994.LOC as c2
from
(SELECT
A.*,
ORA62105.F_UTC2LOCAL(A.CREATED_TS,'(GMT-08:00) Pacific Time (US & Canada); Tijuana') AS CREATED_LCL,
ORA62105.F_UTC2LOCAL(A.LAST_UPD,'(GMT-08:00) Pacific Time (US & Canada); Tijuana') AS LAST_UPD_LCL,
ORA62105.F_UTC2LOCAL(A.REFERENCE_START_DT,'(GMT-08:00) Pacific Time (US & Canada); Tijuana') AS REFERENCE_START_DT_LCL,
ORA62105.F_UTC2LOCAL(A.INDEXED_DATE_0,'(GMT-08:00) Pacific Time (US & Canada); Tijuana') AS INDEXED_DATE_0_LCL
FROM ORA62105.S_ORG_EXT A) T41994
where ( T41994.BU_ID = '1-D3DGK' and T41994.DELETED_STATE = 'N' ) )
select distinct SAWITH0.c1 as c1,
SAWITH0.c2 as c2
from
SAWITH0
Even if I select 2 columns from a table , the select clause in the physical query in OBI server contains 'with clause'.

Need advice in carrer in Java path

Hi,
I am in and out Java Ptrogrammer.
I am in Software industry for round about 5 years.
I started with Web Desgining in HTML, Java Scripts and CSS.
After that I joined a Multinational Company and got into SAP ABAP Team.
I worked in 2 ABAP Projects and then moved to Production Support in Dec 06.
I cleared SCJP 5.0 in Sep 06. At that time my core Java Skills were very good.
But then in Production Support, I worked in HR Application Support. I supprted
4 applications, the main Application was based on Java Swing.
Even if the application were based in Java Swing, Servlets, JSP etc, we didnot need to do
any coding in Java Side. Our work was in the backend. We has to retrieve data from back-end tables
usually through Select queries (Joins) and sometimes we need to write Store Procedures involving
updation of data. Our work also involved writting Shell Scripting. The Database used was Oracle/Sybase.
My project tenure ended in Sep 2007. I then was assigned with Unit Testing (JUnit and Ant) for 6 months
and then QTP Automated Testing Project. After that, I was assigned to SAP NetWeaver Team in SAP Master Data Management. I worked in SAP MDM 5.5 for 6 months August 2008 to Jan 2009 and also appeared in SAP MDM 5.5 Certification in Nov 08. I got 53% and the pass percentage is 55%. Now, I am in Java Project involving
EJB 2.0, Java Web Dynpro and Oracle Database. It is an Event Management System. It also involves DAO Design Pattern.
Now, I am involved in Testing the full application. I need to switch back to Java based development.
What should be the approach? Should I clear SCBCB right now or go for SCJP 6.0?
Or I will again give SCJP 5.0?
I need to built a Java Skill set. It is told that you can't learn if you are not in projects. But it is not true with Java J2EE. You can learn it from Net as many free lancing sites are there. Please advice.
Regards
Taton

I suggest not taking any more certifications (for now). Your main concern should be extending your development skills in those areas you are lacking. I suggest reading a book on EJB 2.0, and reading up on event management and DAO on-line. Also, set up whatever development environment they have (example: Eclipse IDE) and get familiar with it.
For your own long-term career development, I suggest re-writing your resume and having many people review it. Revise it over and over as they point out problems. Have them quiz you on items in your resume (and that aren't in your resume) so you can gain experience on interviewing and answering questions verbally well. I think you have a lot more experience than you realize. Your post seems to me to indicate you don't have confidence to sell yourself in an interview and haven't organized your thoughts to present your argument well yet. Most people don't. Its a skill you have to develop.

Need help with Java programming installation question

Sorry for my lack of knowledge about Java programming, but:....
A while back I thought I had updated my Java Runtime Environment programming. But I now apparently have two programs installed, perhaps through my not handling the installation properly. Those are:
J2SE Runtime Environment 5.0 update 5.0 (a 118MB file)
and:
Java 2 Runtime Environment, SE v 1.4.2_05 (a 108MB file)
Do I need both of these installed? If not, which should I uninstall?
Or, should I just leave it alone, and not worry about it?
Yeah, I don't have much in the way of technical knowledge...
Any help or advice would be appreciated. Thank you.
Bob VanHorst

Thanks for the feedback. I think I'll do just that. Once in a while I have a problem with Java not bringing up a webcam shot, but when that happens, it seems to be more website based than a general condition.

Need help with java will even pay

I need extreme help. I just don't have time lately to write these programs and I have fallen extremely behind. Basically all I need is to pass this class and right now until I can get some more help I just can't make the deadlines. If someone could help me I will pay you just like a tutor.
Requirements for Lab.
You will need to develop a variety of classes for this lab. Specifically, you need to create:
+1. a "PersonGUI" class that displays fields for a person's: firstName, lastName, identificationNum, and sex.+
+2. a "StudentGUI" class that provides Java components for the entry of: classification (freshman, sophomore, junior, senior, or graduate student), and Checkboxes for (a student being in the Honor's program and/or in the ROTC).+
+3. a "FacultyGUI" class that provides Java components for the entry of: rank (instructor, assistant, associate, or full professor), years of service, and salary.+
+4. a "Statistics" class that, when instantiated, creates an object containing an instance variable for each of the the statistical values outlined below. (Each of these instance variables should be declared to be "private".)+
Your main Lab6 class should provide a means for the user to:
+1. Specify the kind of personal data to be entered (Student or Faculty), and+
+2. Then, depending on the choice made, appropriate fields should be displayed to allow the user to input appropriate information for the type of personal data being entered, and+
+3. Controls that support the following functionality:+
* a "CANCEL" control that will terminate any operation currently being performed and return the user to the "Startup" window.
* a "SAVE" control that will cause the just entered data to be harvested from the graphical user interface and the appropriate statistics to be updated. Note: this function may NOT be performed if any of the student or faculty member data fields have not been filled in.
* a "RESET" control that will erase all information recorded to date (i.e., all summary variables are reset to zero).
* a "CLEAR" control that will erase all fields for the personal data currently being entered.
* and a "DISPLAY TOTALS" control that will display, when pressed, the following data:
+1. For students:+
+1. total number of students entered so far,+
+2. number who are male and number who are female,+
+3. number of freshmen, sophomores, juniors, seniors, and graduate students,+
+4. number of students who are in the Honor's program and number who are in the ROTC.+
+2. For faculty:+
+1. total number of faculty entered so far,+
+2. number who are male and number who are female,+
+3. the name and salary of the highest paid faculty member on campus.+
Your program should validate numeric data to the extent:
+1. no numeric field (id number, years of service, or salary) may be left blank by the user. If done so, the user should be alerted to enter a numeric value.+
+2. when the user enters a "years of service" value for a faculty member - the value entered should be verified to be a valid integer value in the range 1 to 50. If the data entered is outside the valid range or is not a valid integer - your program should reject the value and prompt the user that invalid data has been entered and that a new value is necessary.+
+3. when a faculty salary is entered, verify that it is a floating-point value in the range $35,000 to $200,000. Handle invalid data as described above.+
+4. Similarly, if an invalid integer value is entered for the identification number, the value should be rejected and the user prompted to reenter.+
+5. Information should not be saved, nor should statistical values be updated, until all numeric data has been validated.+
Note -- You will be graded on appropriate use of instance vs. local variables, use of methods, and passing parameters and returning appropriate values.
+1. The 'Statistics" class MUST provide "mutator" and "accessor" methods that are required to access values or to modify the values of any variable. REMEMBER ALL VARIABLES ARE DECLARED TO BE "private"!!+
+2. You should implement methods to verify the data, as detailed above. The methods should return boolean values indicating whether the data is acceptable or not.+

Sorry to hear about your problems - lack of time, having fallen behind, imminent failure etc - but none of these are Java problems.
This site deals with Java problems: compiler or runtime behaviour that people can't understand. If you have problems of that sort (and especially if solving those problems would help with the problems you did describe) then post them.
Otherwise you would seem to be in the wrong place.

Need special encoded characters in an Email subject with java 1.3.1_02

I need to find a way to construct an Email through java with Subject lines built using characters from various Asian encodings. Such as Shift-JIS, Chinese Big5, etc.
These encodings cannot be in UTF-8 format and must remain in the native character set.
For testing I have an HTML file constructed using a single line of text with Shift-JIS characters. This file shows properly in web browsers under the Shift-JIS encoding view, and when used to create the body of an email it works perfectly through the DataHandler. However, I cannot get any java Reader to pull the same stream of characters into the Subject of the email. The Subject is always garbage no matter what I do.
Here is a small code sample with the relevant lines:
Session session = Session.getDefaultInstance(System.getProperties(), null);
MimeMessage reSend = new MimeMessage(session);
Transport ship = session.getTransport();
BufferedReader s = new BufferedReader(new InputStreamReader(new FileInputStream("C:\\JavaPrograms\\Converted\\JISConv.html"), "SJIS"));
String resub = s.readLine();
s.close();
reSend.setSubject(resub);
DataHandler collect = new DataHandler(new FileDataSource("C:\\JavaPrograms\\Converted\\JISConv.html"));
reSend.setDataHandler(collect);
ship.send(reSend);If I use the "SJIS" encoding in the InputStreamReader above, all characters are shown as "?". If I delete it entirely and use the system default, I get half of the characters and the rest are garbage. I can generate either of those results using various other Japanese and Western encoding definitions.
I have tried using the above code, also DataHandlers for the Subject, FileReader directly to a String, ByteArrayInputStreams, and StringBuffers. So far everything I try ends up at the same result.
Can anyone help me out? I really need this to work. If I can get this one encoding to work, then I should be able to program case switches for the other encodings.
Thanks kindly!
Kurt Jackson

First this is an issue with javamail and not with java.
What makes you think that the mime standard allows what you want to do?
Both of your 'tests' have been done using alternatives which do support alternative encodings.
These encodings cannot be in UTF-8 format and must remain in the native character set.That seems rather unlikely to me. Email is transported using one encoding. Certainly SMTP uses only ascii. So what ever you put in there is going to be ASCII no matter what you do to it. I suppose something at the end might try to read it using an alternative encoding but then what happens when someone really wants to send those ASCII characters?
Mime, I believe, is built on SMTP. And the subject line is still SMTP and thus ASCII.
Here is one link that covers mime (you might want to check the backing references though.)
http://www.mindspring.com/~mgrand/mime.html
I believe there is some sort of official or unofficial standard for doing what you want. I would suggest that you start by getting that first. I would suspect JavaMail doesn't support it.
Once you have a standard to follow you have the following choices..
- Modify JavaMail directly to support this (this then becomes a non-distributable solution.)
- Extend JavaMail do support this. This might or might not be possible.
- Write your own implementation (don't use JavaMail.)
- Find another solution from another source that already implements this.

Can someone pls help me with java on my macbook pro because after i download the mountain lion java has died and i need java to see streaming quotes from stock market

can someone pls help me with java on my macbook pro because after i download the mountain lion java has died and i need java to see streaming quotes from stock market

Java is no longer included in Mac OS X by default. If you want Java, you will have to install it.
However, note that you should think twice before installing Java for such a trivial need as looking at stock market quotes. There are other ways to get that information that don't involve Java, and using Java in your web browser is a HUGE security risk right now. Java has been vulnerable to attack almost constantly for the last year, and has become a very popular, frequently used method for getting malware installed via "drive-by downloads." You really, truly don't want to be using it. See:
Java is vulnerable… Again?!

Day 2 with ATV, may need advice.

iPhoNettie wrote:Apple Genius-tried syncing thru ethernet cable
I need to know if this is possible with ethernet cable only between ATV/MacPro vs Airport wireless.
I've spent hours with this 32gb ATV to just load and it's been nothing but long hours.
One trick that will not work.
Macpro is mainly using ethernet cable to the wireless access 24/7.
I leave his airport off.
I'm on day two of the first attempt at using ATV, it has been sitting for a year never used.
This all started yesterday with a members advice using ATP, vs iPhone connected to RXv3900.
What a Great iDea.
I turned Airport on the MacPro. Not sure why I did. In the end, you need to.
Plug in ATV, and started in last night. Noticing it's Quite slow on Airport.
Discovered there is no real-time status of the load you checked/selected in iTunes to know if it's too much.
Sure enough at present, the 5th time of de-selecting is to make room again.
At 50 something, we have a set logic that's hardened.
If dishwasher is full & ready, do you unload/reload complete to add one item?
Apparently Apple does.
There maybe an update that is needed.
It's not showing up by default or where to access if there is.
ATV finally finished with 8.5Gb free. I'll see if update is found.
Still very reluctant to do update with ATV actually working.
Getting to the chase here, can ATV & MacPro be direct linked w/ethernet cable?
One test I just tried while ATV was loading again, I shut Airport off on the MacPro.
ATV immediately disconnected from iTunes. Whoops.
My test was to see if ATV would still get through to Mac wirelessly by accessing wifi MacPro is wired to. Nope.
Is this telling me I don't need Comcast's wifi to connect the 2? ATV/MacPro only for loading ATV.
Can ATV connect it's path directly to MacPro's Airport? Skipping Comcast's wifi.
I guess my final question is/ can ATV connect to MacPro with only angry twisted copper wire?
Also, is there any advantage with MacPro on ethernet cable and Airport on at the same time?
I see no results either way.
I hope my versing is with some accuracy.
I'm not up on the latest politically correct lingo.
For sure of one thing, a 1Tb drive is on it's way for a new mission.
For the first time, I'm viewing trailers on ATV, and I have Airport shut off on MacPro.
This is good. I was afraid up to this point.
Thanks'

Yes they should provided you've registered the AppleTv to sync with iTunes on the Mac Pro account - do you remember setting AppleTV to connect to iTunes by entering a 5 digit code in iTunes from AppleTV?
Yes, I have performed all the loading of ATV by wireless from iTunes from the MacPro.
This simple ethernet connection should just work to sync from previous reports.
This will be great. The main reason is to take ATV to the cabin or shop with no internet access.
This should work if all you're doing is syncing and then putting the AppleTv back where you want to use it.
However, if you want to connect by ethernet all the time, then the direct connection to the Mac Pro will not allow AppleTV to access the internet for various store/photo/YouTube features or to authorise playback of some iTunes Store material/rentals etc, unless you've configured internet sharing over the Mac Pro ethernet port and the Mac Pro is connected to the internet either via it's other ethernet port or wireless.
Thank You, it's not a priority to access these features with ATV.
Your best bet is to have AppleTv connect to a router to see the internet itself and to see the Mac Pro on the local network.
Great, and I really appreciate your quick reply.
Have a Great Day.

Major Issues with installing 4tb internal. Really need advice please

In the process of a long needed upgrade to my 2010 Mac Pro Quad core 2.8 and have run into a serious headache that I really need advice on so I can get back to work. I've already spent 2 days dealing with all of this...
Just did a new SSD install and Migration which went fine but I'm also updating the rest of the internal drives. My main (non boot) drive was being upgraded from a Seagate Barracuda 3tb to a 4th Deskstar NAS (it was showing as compatible with my desktop, see links below). My 3tb ran fine for years but now due to it being heavily used I want to switch to a new drive and I can also use a bit more space.
The issue I'm running into is that initially on boot, my system was telling me it couldn't recognize the disk and it wasn't even showing up in Disk Utility. I had to purchase a SATA USB 3 kit to attach it as an external to get it to show which worked without problem. With the USB kit I was then able to partition it (GUID, Mac OS extended journaled) and format it properly. After reinserting the drive into my tower as an internal it failed to show again. After a few attempts of restarts and trying various bays it popped up but showed as a non formatted drive and I was told again that the system didn't recognise it. I was then given the option to initialise and was then actually able to then format and partition it though Disk Utility while it was installed as an internal.
Figured that was problem solved but when I went to check the drive and getting ready to transfer files over I noticed that Disk Utility was only allowing the First Aid and Partition options but not Erase, RAID, Restore which I'd never seen before. I then also noticed that none of the drive connection info was in the same format nor will it even provide drive bay info, connection info or read/write status (See screen shots). This is what I can't figure out and really need to clarify before I put full trust into using this drive.
Any info would be greatly appreciated...
Deskstar 4tb internal info which is installed in Bay 2
3tb Seagate which I trying to retire and transfer from.
Here are the weblinks to the Deskstar 4tb drive and the compatibility list but I support isn't allowing me to add direct links so add the www. before hand.
(Drive - eshop.macsales.com/item/HGST/0S03664/) (compatibility list - eshop.macsales.com/Descriptions/specs/Framework.cfm?page=macpromid2010.html).

What OSX version?
Disk Utility in later versions of ML and I think Mavericks have problems formatting with 4 TB internal drives.
