Java Fresher

Hi Everybody,
I have shifted my career from "Functional Testing" side to Java.
Please can you suggest exact "*Java Learning Path*" and required URL's for a Java fresher.
I mean to say like CoreJava, J2EE,....
I need to get the required Java skills for a Project.
Instead of getting theoretical knowledge I need to gain more practical exposure in Programming side.
I would appreciate your inputs (suggestions.)
Looking forward.....for your replay.
Thanks in advance.
Regards,
Gopal.

JAVA Fresher-Should I join Sun Authorised learning Centre?

Hello friends,
I m a BCA Graduated in 2004 from India. I have 2 years of experience as Web Developer(PHP). Due to Family problems I could not go for regular MCA. Presently persuing MCA from ICFAI, Tripura first Semester. But I m not able to get any job in Big IT Giants like Infosys, TCS as these companies don't have requirements for PHP Developers and to join as a fresher I m not eligible to apply as I m 2004 passout and these companies demand atleast 2005 passout.
Therefore I m thinking of migrating to JAVA. I don't know ABC of JAVA. There are a number of local institutes teaching JAVA for 10k-15K INR in Delhi/NCR region and providing fake experience certificate for 2 years in JAVA to me as I have 2 years of industry experience.
I need help from all experienced people out there. Should I join a local institute or should I go for Sun authorised learning Centre?
I know about one Authorised learning Centre, SQLStar International. They charge around 33000 INR for 256 hrs of training to be completed in 64 working days. They claim that their training prepares a person for SCJP and SCWCD exam cost of which is 7200 Per Exam.
So total cost is 33000 + 7200 + 7200 = 47400 INR
Please tell me if its a right decision to spend this much amount on training and certification?
Does it make any difference while on a Job Hunt if you are trained from a Authorised learning Centre or a local centre?
Will it be easy to get job after this training and certification?
If someone want, I can mail him/her couse contents of SQLStar and a local Institute for comparison.
Please guys I need honest advice.
Thankyou all for your time and efforts.

Hi, my name is Jeffry (Indonesia)
Actually, if you can do self-study, you can do self learning with java book, after that, you can submit E-practice Exam for scjp, and then you take the exam
If the employer has a choice, he or she will choose the job seeker with the SCJP certification.
Sun microsystems created the Java technology, of course their training courses support for the material covered in any certification exam such as SCJA, SCJP, SCJD, SCMAD, etc.
I already get certified in 27 August 2007, in my experience, I studied so many Java books, and then I took SL-275 training, E-practice exam, and the the SCJP exam. That's all that I can do to share my experience, the choice is yours. When you passed the exam, don't forget to share experience and score (if you want to share your score, my score is 68%)

New To Advanced Java EJB Problen

I m a adv java fresher
I 've worked in JSP, Servlets, JRUN, Tomcat, JDBC But i don't want to learn EJB. This is so hard to learn.
Is there any good alternates that industry accepts.
Also please tell me resources available to learn & practice EJBs
Are Java Web Services not an excellent alternate to EJB

Are Java Web Services not an excellent alternate to EJB.Although they are similar ...I wouldn't say one is a substitute for the other. One nice example of a web service I have seen is one used by several of the library automation programs leading the market these days. Each 'title' you inquire about can have a book jacket in gif form ...an important visual cue for young library patrons.
Now, suppose you forced each organization that purchased your automation system to create, format, and house their own .gis for this purpose? No way, users scanning ...keeping current ...storing ...their own gifs? Push that responsibility on to them? No way. Before long your nice handywork would start to look like garbage with half missing jacket visuals ...like a patchwork mosaic!
Instead ...one single (and that is the key to our discussion here ...single) company has set up a web service so that all users from all vendors can hook in (paid subscription) and download (realtime) .gif's for whatever titles they (the users) may have in their active system at each moment. Remember I said 'all the application vendors' ...meaning that a separate company got smart, saw a need ...and developed a web service to supply the entire market with book jacket pictures on demand. The automation vendors simply build their applications to take advantage of an offered service. That is the concept of a web service. It's not really an 'enterprise solution' ...its a unique and focused 'piece' of a larger picture. Hey ...another very cool area of study ...but not really an 'alternative' to an EJB solution.
With an EJB solution, remember I said it was for DBA guys. It is a way of modelling your enterprise data in RAM, making it more scaleable than hitting the db and disk with thousands of hits per hour. It uses the traditional db for (permanent) persistent, but keeps multiple 'instances' of certain views of your data in the memory of the server, like a repository of your data held ready to go out the shute, even to multiple callers concurrently. CMP makes it easy to switch db vendors without having to rewrite large sections of your application in order to do so. These are some of what EJB solutions offer, and although similar ...it isn't exactly the same as what a singular web service is really trying to offer.
Now hey, having said that ...there are a lot of similarities for sure. I almost got the idea that MS was trying to tell me (at some recent .NET training ...barf) to make a bunch of web services collected together ...and that somehow that was supposed to rival an EJB application server solution. Hmmm, maybe there is actually varying definitions and visions for what a web service will be. Maybe you could 'copy' the EJB methodology and implement it as a collection of web services ...but somehow that seems like it might be going off in the bush. To me, they are similar solutions for different problems.
Maybe someone else can shed more light ...I hope you can gleen something meaningful from my brief comparisons. My point was just to imply that they aren't really a 'substitute' for one another, which is what I think you mean when you say "Are Java Web Services not an excellent alternate to EJB ".

As i am fresher Please share the doc of ECMA script using java script in SharePoint 2013 step by step also how we can insert,update,delete records in list using ECMA script.
Thanks and Regards, Rangnath Mali

Hi,
According to your post, my understanding is that you want to use JavaScript to work with SharePoint list.
To create list items, we can create a ListItemCreationInformation object, set its properties, and pass it as parameter to the addItem(parameters) function
of the List object.
To set list item properties, we can use a column indexer to make an assignment, and call the update() function so that changes will take effect when you callexecuteQueryAsync(succeededCallback,
failedCallback).
And to delete a list item, call the deleteObject() function on the object.
There is an MSDN article about the details steps of this topic, you can have a look at it.

Fresh Java install; browser doesn't recognize jnlp MIME type...

Hi Folks,
I was working with a client today to install a JWS app on a number of workstations. First one went fine. Just to be sure they had everything right, switched to another Windows PC. Browser displayed the jnlp file as XML. OK, I figured, must be missing the JRE. So, okay, we install the lastest 1.5 from www.java.com. Well, the browser still doesn't pick up on the MIME type setting and launch JWS--just displays the XML.
And yes, the server is sending the right MIME information because it works on dozens of other PC's at dozens of other sites as well as on the first PC we tried at that location. So then I figure, well, we'll just tell Mozilla that it needs to associate the right application with the MIME type/extension in question--there's no where to add a new association (at least not that I can find).
Any suggestions gratefully accepted.
John

Sorry for the inaccuracy there. We actually tried both Firefox and IE--same result on both of them.
(The 1.5 version of JWS doesn't allow you to put in the URL there--a disappointing circumstance. The whole thing was clearly more complicated than it seemed to me at first--there were already 3 other JREs installed.)

Java 6 SDK won't install on fresh Windows 7 system

"Count not find main class: org.openinstaller.core.EngineBootstrap. Program will exit."
Is there something else I need to install first?

You know, I've not installed Java EE for a while--but the last time I did, I think you may have to have had a JRE installed. But I would not guarentee that, since the first thing I do when I get a machine up is to install the most current JDK and JRE.
In your situation, it sounds more like your installer may be corrupt.
Are you looking to install the Enterprise Edition?

Firefox after v 8 hangs and crashes done all "firefox hangs" suggestions. Installed fresh java, flash, safemode, only thing that works is to return to v 8

Last FF version that works flawless on my home rigis v8. From v9 on hangs pages, hangs entire computer, "not responding" for long periods of time. Have completed all the "firefox hangs" suggestions. Reinstalled clean, reinstalled clean flash, ran w/ new and w/o Java, safemode, hardware acceleration off, clean profiles... Only savior is to return to v 8. Same package of addons are loaded on other computers I have w/ no issues. Graphics drivers are up to date/ XP drivers and releases are up to date. Use the same settings for v8 and each that have updated since. Have set to not update in v8 but it constantly updates itself and begins the crash/hang cycles. Resources are using less the 20% cpu and ram when hanging is occurring.

Problem Launching Java Applet with Plug-in: Version 1.4.2_01

Hello out there:
I recently installed j2re-1.4.2_01 on my home computer but have been unable to access Web sites emmploying JAva applets. The following is an email exchange with Jeff Hall of Lowell Observatory, manager of an educational site hosted by Lowell, trying to resolve my problem. The messages are better understood if read in reverse order.
I'm hoping that someone will recognize the source of my problem and can recommmend a solution. I would appreciate any help offered.
Thanks,
Mike Coucke
Hi Jeff:
Well, I guess the problem lies with me somewhere. Here's my answer/status to your questions/suggestions:
1) I'm using MS Windows Me version 4.90.3000
2) I do have the directory C:\Windows\.jpi_cache\jar\, but the only thing in it is an empty folder labeled "1.0". The file LP.jar does not exist anywhere on my hard drive.
3) I tried several game sites that utilized Java applets and got the same results: the Java cup in the upper left corner followed a few seconds later by the red "X". So, evidently the problem is somewhere on my end.
I'm going to post our email exchanges in a Java Users Forum managed by Sun to see if anyone out there can solve my problem. However, if you have any more suggestions, I'll be glad to try them.
Thanks for the help.

Mike,
Rats! What version of Windows are you using? It's a little strange to
see the user directory set to C:\Windows; if you're using XP, I'd expect
it to be something like C:\Documents and Settings\Mike Coucke. In any
event, the output that is of concern is these two lines:
java.lang.ClassNotFoundException: LPRemote.class
Caused by: java.net.UnknownHostException: proxy
It looks like your browser is not finding our server's IP when it comes
time to download the necessary Java code.
LPRemote.class is the fundamental code that runs LOPARC, and your
browser should be downloading it automatically when you click connect.
LPRemote.class is stored along with a bunch of other classes in a file
called "LP.jar" that you download from our server. So, if you go to C:
in Windows Explorer and do a file search for LP.jar, you should find it.
On my machine, it's stored in a directory called ".jpi_cache\jar\" in my
user home directory. Let me know if you have this file, or the
jpi-cache directory.
One other thing you might try is going to a different site that you know
uses Java applets -- I think some of the online game rooms at Yahoo use
Java. See if other sites that use Java load correctly. Then we'll know
if it's our server specifically, or a more general problem on your end.

Hello Jeff:
I still have the Java "blues". I followed your instructions, but am still unable to launch a LOPARC session. After an initial failure, I uninstalled all three Java versions I had (1.4.0, 1.4.1, 1.4.2), then reinstalled 1.4.2_01 from the Sun website.
Now, when I try to launch LOPARC, I initially get a blank window with the Java cup in the upper left corner. After about 20 seconds, the cup changes to a red "X". During those 20 seconds, the following appear in the IE message bar at the bottom of the window: "Applet LPRemote notinited" (their spelling) which changes to "Loading Java Applet Failed..." when the red "X" appears.
Following is a copy of the log from my Java Console during all of this:

I'm not a Java expert, so this may be more information than you ever wanted to see.
Once again, I hope that you can help. My experience has been that I usually have some obscure option set incorrectly and that causes me great grief.
Thanks fo your help,

Hi Mike,
Try it now. I think this problem has arisen because Sun just
released a new version of the Plug-in (1.4.2), and when we released the
public beta of LOPARC, only one relevant version (1.4.0) was available
and the LOPARC code was written to look for that by default. I have
just recoded the relevant routines so they should now cause your browser
to simply pick up the latest 1.4 version of the Plug-in you have
installed, whatever it is. I "broke" Java on my machine to replicate
your problem, and the code I inserted today did fix it. Hopefully it
will have the same effect for you. I am running IE 6 and plugin
1.4.2_01 (as accessed via Tools->Sun Java Console).
One broader problem: some (non-LOPARC-specific) users on the Sun
forums have reported the "JRE collision" you are seeing when multiple
versions of the Plug-in are installed on the same machine. So if the
fix I made to our code doesn't work, one option would be to uninstall
all Java components from your computer and do a fresh install of the
latest runtime environment.
Let me know how/if this works. Thanks for the feedback and for your
patience.
Best regards,
Jeff Hall

Hello Jeff:
So far, I have been unable to launch a LOPARC session. I repeatedly
get the following error message:
"Exception: java.lang.ClassNotFoundException: LPRemote.class"
My browser is MS Internet Explorer version 6.0.2800.1106 Initially I was
using Java Plug-In version 1.4.1 and received the error message. I went
to the Sun website and downloaded/installed Java Plug-In version 1.4.2
and still get the message.
Before I try to launch LOPARC, I can select Tools->Sun Java Console from
IE's pull down menu to check my Java Plug-In version. When I try to
launch LOPARC, I get the following message:
"Applet(s) in this HTML page requires a version of Java different from
the one the browser is currently using. In order to run the applet(s)
in this HTML page, a new browser session is required, press 'Yes' to
start a new browser session." If I select 'No', I get the following
message: "Java Plug-in detected JRE collission"
If I select 'Yes', a new browser window opens and then I get the first
message above.
Can you help?

Dear Michael Coucke:
Thank you for registering with Lowell Observatory's online education
site. We hope you enjoy using it and visit regularly as we continue to
expand its features and capabilities. This is a one-time welcoming
email.
For your records, your user ID is xxxxx, and your password is #########.
You'll need to supply these each time you log in.
This site gives you access to research-grade equipment including a 16"
telescope, CCD detector, and image processing software. Our online
archive of data is now available 24/7. The telescope will be opening to
our onsite users in May, and on select nights to the Internet at large
in June.
We have designed this site so you don't need a huge monitor or a
supercomputer to use it. All pages are viewable on screens running at
800x600 resolution or higher. To use LOPARC, you'll need a Java-enabled
browser with the Java 1.4 plug-in installed. If you don't have the
plug-in, you'll be prompted to download it the first time you attempt to
connect. This is an admittedly large (9 MB) but one-time-only download.
This site works correctly under Internet Explorer version 5 or higher.
If you use Netscape, you must be running version 6 or higher, and
display or applet behavior anomalies may occur.
If at any time you can't connect to our server, simply try again later.
We do experience several power outages each year, particularly during
Flagstaff's summer thunderstorm season. Our server is fully protected
and backed up, and can be quickly brought back on line, but any active
user sessions will be lost. Thanks for your patience during these
inevitable downtimes.
Your questions, comments, suggestions, and bug reports about this site
are always welcome. On behalf of the LOPARC development team, thanks
for signing up!

Hi Mike,
I see this in your logs:
Java(TM) Plug-in: Version 1.4.2_01
Using JRE version 1.4.2_01 Java HotSpot(TM) Client VM
User home directory = C:\WINDOWS
Proxy Configuration: Manual Configuration
Proxy: http=proxy,https=proxy,ftp=proxy,gopher=proxy
Proxy Overrides:
I just helped my Dad set up his computer with a new
cable modem, and had the situation where we couldn't
access any secure Web sites. The cable folks had us
disable the proxy. It looks like the error message is
saying it can't find your proxy server, and the logs
you posted say that you've decided to configure your
proxy manually, rather than using the settings from
IE (which is how mine is set up in the plugin
control panel.)
Could that be the problem?
