Java and Display Issues in Plus

Hi everyone
Please reply whether you have or have not seen any of the following:
I'm working on a client site where we have some machines working just fine and others are giving corbaserver errors. Copying data from a worksheet into Excel using CTRL-C | CTRL-V does not seem to work for some machines and so they have to use the Copy and Paste buttons. Curiously, when they do this they get an additional empty column whereas on the machines where CTRL-C | CTRL-V works they don't get the blank column.
The other issue we are seeing is that after a short period of time, Plus stops running the queries automatically. Any change the user makes, such as adding a new item, adding a sort, moving a column position does not take effect until the Refresh button is clicked.
There is a combination of IE6 and IE7, with all machines being XP with most on SP2 and many on SP3.
I am suspicious of the XP SP3 when combined with IE7 but would like to know whether anyone else has experienced issues. We are running 10.1.2.3 with CP4 and our Java is Sun 1.6.0_15
Please reply with either a we are having no problems with this combination or whether you have noticed similar issues. If you have seen issues and got a fix or workaround please let me know. I'm also interested in knowing which combination of Java, Discoverer, operating system and IE works for you.
Best wishes
Michael

Michael,
Our production server was recently upgraded to 10.1.2.3, CP5 with Java 1.4.2_06. Prior to this upgrade we recommended that users function with I.E. 6.0 and Firefox 2.0. We experienced issues with later browser versions. On my personal workstation I have Windows XP, SP2, I.E. 6.0, Firefox 2.0 and now Java 1.6.0_16. We are now testing the later version of Java on our test OAS. And we are testing out the later browser versions as we speak. The first thing that I would recommend is to add the Java Runtime parameter of -Xmx256M, in the Java Control Panel. I had some session locks prior to my adding this parameter. I am testing access to both servers with Java 6 installed on my workstation. Access to Java 6 performed better after I added the runtime parameters. Access to Java 4 with I.E. gives a warning message and performs very slowly. Mozilla Firefox does to seem to care, no warning and similar performance as Java 6 on the server side. I have not done very much testing with I.E. 7.0 and Firefox 3.0 as of yet with the newer Java version. I am now accessing that environment and it is running very slowly. Part of the issue may be my PC performance but I do not like what I see. Way too slow. This is the browser functionality not the workbook execution time. I added the Java Runtime parameter of
-Xmx256M and it now performs better.
I did the Ctrl-C|Ctrl-V with both I.E. and Firefox and did not experience the problem you discribed. I aslo did not encounter the other problems that you reported. We the corbaserver errors in a Discoverer pop-up window, Java Console or OEM session log?
You may be correct with the SP3 as being at least one of the culprits. I do not have that patch on either workstation so I cannot test for you.

Running Interactive commands in java and displaying the output.

Hi All,
I'm running a sample code to execute a user defined command (cmd1) and display the results. The output of the command when executed in command prompt is
(1) Executing the command cmd1
(2) Do you want to continue(Y/N)_ <waits for user input>
(3) Based on user input
(Y) Displays the results
(N) Interrupted
But i'm facing problem when i execute the below code. When the results are being displayed instead of displaying line(1) and (2) and then waiting for the input- the code waits for the input and then only displays the results.
O/p
inside output
inside input
y (------ gets the input and then only displays the results).
Executing the command cmd1
Do you want to continue(Y/N)
results
Please help out how to resolve this issue.
Thanks.

Console input is line buffered. This means you only get the first character a line after the newline has been inputed.
The same thing happen if you just type on the console.
I am not aware of any simple way around this.
IDEs get around this by changing the application run so that the input/output is captured as it happens and sent over a socket connection.

MacBook Pro Startup and Display Issues

I've been having some random problems with my MacBook Pro (2.16 GHz, 2 GB RAM, 100 GB 7200 rpm hard drive, ATI Radeon X1600 graphics). Specifically:
1. Lines across the screen and purple boxes sometimes appear.
2. The graphic effects (e.g. zooming a window) sometimes get "frozen" on the screen. In other words a remnant from the animation will stay until the window is refreshed.
3. The Mac sometimes freezes during the startup process. Sometimes the login screen will be unresponsive and other times the Mac will almost bootup but fail when loading startup items.
4. Less frequently the Mac will freeze randomly. I previously had iStat Menus installed and each time the MacBook Pro froze up it indicated both read and write disk activities.
Yesterday I decided to wipe the machine clean and start from scratch in case there were a software issue or corruption on the hard drive that was causing my woes. I completely erased my hard drive and even zeroed the entire disk to make sure everything was completely wiped out. I also disconnected all peripherals to simplify things as much as possible.
The first time I tried the reinstall everything completed successfully but the "Welcome" movie froze part way through. I then had problems running the install again. I was able to boot off the Leopard DVD, but the machine froze a couple of clicks into the install procedure. After numerous tries I was able to erase the hard drive once again and install Leopard. This completed successfully and I installed all updates.
The problems started to show up again almost immediately, however. I installed iLife and iWork and all the updates and had the computer freeze up on me again during a reboot. I also noticed that the display issues started to show up again even before installing any third-party software.
I've tried running disk tests with Drive Genius 2.1, but no errors have been reported. I've also used the freeware Rember program to run memory tests but have yet to see any errors. Sometimes my Mac powers up without any problems and once it's powered up it often stays running for days. The display issues appear quite frequently. I've using iStat Menus to keep an eye on the temperature sensors and everything appears to be normal - so it doesn't appear to be temperature related.
Fortunately the computer's still covered under the extended AppleCare warranty, but I would like to have some idea what's going on before I take it in just in case they're not able to reproduce the issues.
Any suggestions and insights would be GREATLY appreciated. Thanks in advance for reading my rather long-winded message.
Cheers,
Tim

I took my MacBook Pro in for repair and it turned out to be an issue with the logic board. I had the logic board replaced (fortunately it was covered under my extended AppleCare warranty) and these problems are a thing of the past.

New to java and having issues trying to modify sample code.

i was trying to edit the following code to add about 10+ more labels and textfields and save the information to the contacts.dat in the code. it currently displays all the fields i entered, but it only saves the first 7 fields information?? not sure why. also i was trying to just line the fields up using a flowlayout but it just errors. anyone have any suggestions?

Unresponsive Java and further issues.

Hi all,
I'm a student studying Java, and I've been around Java for a while. I've lately put a new computer together and I'm running a legit copy of XP pro on it. Now when I installed Java on it, I had it verified and the website indicated that it has been successfully installed. However, every time I get on a website that uses Java, or I try to run a simple home made program on Java, only an empty window appears with no contents. The size of the window definately varries depending on the size it was designed to. Sometime, I even see java's startup logo an a part of the program shows up. But its usually not in working condition and at that point. All I can do at that point is close it, but then everything in windows becomes non-responsive. None of the icons work, start doesn't work, not even alt-ctrl-del. The only moving thing is my mouse arrow at that point. Then after about 20 seconds the already non-responsive computer freezes completely!
I've not been able to find a reason for this issue around, nor a way to fix it. I would like to know if anybody has any idea what is wrong with this.
Thanks and regards,
Vala

Michael,
Our production server was recently upgraded to 10.1.2.3, CP5 with Java 1.4.2_06. Prior to this upgrade we recommended that users function with I.E. 6.0 and Firefox 2.0. We experienced issues with later browser versions. On my personal workstation I have Windows XP, SP2, I.E. 6.0, Firefox 2.0 and now Java 1.6.0_16. We are now testing the later version of Java on our test OAS. And we are testing out the later browser versions as we speak. The first thing that I would recommend is to add the Java Runtime parameter of -Xmx256M, in the Java Control Panel. I had some session locks prior to my adding this parameter. I am testing access to both servers with Java 6 installed on my workstation. Access to Java 6 performed better after I added the runtime parameters. Access to Java 4 with I.E. gives a warning message and performs very slowly. Mozilla Firefox does to seem to care, no warning and similar performance as Java 6 on the server side. I have not done very much testing with I.E. 7.0 and Firefox 3.0 as of yet with the newer Java version. I am now accessing that environment and it is running very slowly. Part of the issue may be my PC performance but I do not like what I see. Way too slow. This is the browser functionality not the workbook execution time. I added the Java Runtime parameter of
-Xmx256M and it now performs better.
I did the Ctrl-C|Ctrl-V with both I.E. and Firefox and did not experience the problem you discribed. I aslo did not encounter the other problems that you reported. We the corbaserver errors in a Discoverer pop-up window, Java Console or OEM session log?
You may be correct with the SP3 as being at least one of the culprits. I do not have that patch on either workstation so I cannot test for you.

Creating Bar Charts using Java and Display in jsp

Hi..Is it possible to create a servlet that processes data from database and display the values as Bar Charts in jsp pages. If its possible, is there any examples on how to achieve that?

I don't get it. You already know what needs to be done to solve your problem, the only thing you are missing is the HOW. That's the easy part, if only you break down what you have to know:
1) how do I show an image on a website (this is a basic HTML question actually, not actually related to servlets/JSPs directly)
2) how do I fetch the path from a database (JDBC question) so that I can use this path to link to my image on disc
So what is preventing you from figuring out how to do these two simple tasks? Some clever google searches should give you all the information you need in no time.
by the way: are you sure that you need to store these paths in the database? Is this part of some file upload component?

CCP 2.6 Javascript error and display issues

Hello ,
I am atttempting to run CCP2.6 and have tried clearing cache on IE (temp internet/website files, cookies, history) and removed all Java files including trace/log files, chaced apps and applets , and installed apps and applets.Also ran CCP as admin. Essentially followed all guidelines to solution to discussion "CCP 2.5 Javascript Error" but has not resolved issue.
I still get the error below and the bottom 2/3 of the CCP screen is not displayed/rendered. Content is only rendered within a sliver of entire window size , at top part of the window. It appears as if Java should be rendering content at mid/bottom section of window but never does, although a tempory splash screen does appear as if it is "attempting".

PDF preview and display issue : NWDS CE 7.1 SP05+ALD 7.1

Hi All
I am creating a webdynpro java application in NWDS 7.1 SP 05. This application has an interactive form ui element. The livecycle designer version is 7.1 and reader versions tried are 8 and 9.
The issue is that the pdf preview in NWDS is blank and also I am getting blank white space instead of the form when i deploy the application on a browser.
I have used NWDS 7.1, SP05 + ALD 7.1 combination on another system and there i can see the form in NWDS pdf preview.
I am completely stuck, please let me know of any way out.
Thanks
Lisha

Hi,
Try to uninstall adobe life cycle designer and install it onceagain..
Even we faced some times this problem, but better to use higher version of adobe life cycle designer like 8.0 whiuch will be compatible to your NWDS version...
Hope this helps you in resolving the problem...
Regards,
Saleem

I can't give a specific response, but if possible, upgrade to LCD 8.0 - it is much smoother to use than 7.1.
I almost pulled out all my hair working with 7.1

Linux installation and display issues

PROBLEM:
During installation, the following error occurs:
No Java virtual machine could be found from your PATH
environment variable. You must install a VM prior to
running this program.
RESOLUTION:
Install Java 1.5 and make sure that it's in your PATH environment. To
doublecheck that Java 1.5, simply
type 'java -version'.
PROBLEM:
When opening any display view, the following error occurs and nothing shows
up:
ERROR GuardianApplication [main] : Registry does not exist, creating
default registry
Unhandled event loop exception
Reason:
No more handles (java.lang.UnsatisfiedLinkError:
/<GUARDIAN_INSTALL_DIR>/configuration/
org.eclipse.osgi/bundles/72/1/.cp/libswt-mozilla-gtk-3139.so: libstdc++.so.5:
cannot open shared
object file: No such file or directory)
RESOLUTION:
Add your browser's library dependencies by editing the /etc/ld.so.conf and
add /<PATH>/firefox or /
<PATH>/mozilla directory.
Example: /usr/lib/firefox-1.5.0.7
Make sure that the path to firefox or mozilla contains the
/usr/lib/firefox-1.5.0.7/libxpcom.so. After
that, run ldconfig command to update your library.
Install compat-libstdc++-33 library. For Fedora users, simply type: "yum
install compat-libstdc+
+-33.i386" as root. Relaunch Guardian.

I am really interested on comments. Anyway check also those sites about Linux on Toshiba notebooks:

Major tree and display issue.........

Hi guys! I am having a problem whereby when I click on a tree node(Folder), I want all the images contained in that folder to be displayed on a JPanel which I created. By the way, the tree and panel are added to a splitpane. Tree on the right, and panel on the left. I will really appreciate it if someone can assist. Thanks a lot in advance!!
Cheers,
Bolo

Hi,
You see this demo, it displays all the images of a selected folder in the tree in the right panel. You can customize the layout of the right panel to suit your need.

Has the new Early 2013 Retina Macbook Pro still lag and display issues?

Hello. I've never had a Mac before and I'm thinking of buying the new "early 2013" 15-inch (2.7 Ghz, 16Gb Ram, $2799) Retina Macbook Pro. I live in Argentina but I'm going to NYC in a couple of weeks and I want to get one there. The thing is, that I can not be returning it 2 or 3 times like I read a lot of peple had to, because I'll be coming back home after 2 weeks and here they will only fix it, not replace it for a new one, and that could take months.
So, I want to know if you guys can help me decide if I should go for it or not, if these image retention and burn in and ui lag issues appear to be fixed with this new model or if it is still the same. If I don't buy this one I'll be getting the new Samsung Series 7 Chronos they showed in CES 2013, still not available in the market. Thanks a lot!

I just checked and I have the LG SJA2, too. I didn't notice any Image retention at first, I tested it with the chessboard test for 5 or 6 minutes, it showed no IR. But with 10 minutes I can see a bit of IR. Nothing that can affect the normal use of the computer, I mean I have to put the chessboard for 10 minutes and then change to grey to notice it, but it does exist and is the SJA2 from LG. If it doesn't get worst, I think it doesn't even matter. I just hope it doesn't get worst.
FWIW, I noticed that until I stopped looking at the chessboard before it switched; my eyes had image retention. But in that awfully long thread on the subject, some have insisted that if it's an LG, it's trouble so I guess there's no guarantee. (BTW, I was writing this when you tried the test again - ocular image retention?)
Not to hijack the thread, but shortly after I posted that "good news" about SJA2, my rMBP simply refused to start at all; it was totally inert. Charging, not charging, SMC reset, nothing helped. Tech support's only solution was bring it in to be fixed.
On a hunch, and remembering something about magnets in the top of the display activating a reed switch in the base, probably near the trackpad, I lifted the front of the Mac about 1/4" inch and let it drop. Bingo! The Mac has operated properly so far. I suspect the reed switch was stuck in the wrong position, and some evidence suggests it was that way out of the box and my fix corrected it.

Freezing and display issue

Dear All,
I had this imac from 2010. Now it's creating some issues. Daily when i start this Imac, its freeze on gray screen and its also show scrambled display. But after 5 or 6 time immediate power down and on. I am able to use the operating system. It’s a very strange problem after getting heat or something it able for use. I also reset the smc and Pram reset. I don’t think its operating system problem. Kindly suggest solution which work

This sounds possibly graphics related and sounds as though you are experiencing kernel panics.
Please post a copy of your latest kernel panic in your reply. To find the log, open Console application and look under System Diagnostic Reports. The log will start with "kernel_" and end in ".panic". Post the whole panic report in your reply.

Java and Maven issues after upgrading OSX to Maverick 10.9.2

I upgraded my MacBookAir to Maverick and now it can't detect Java VM and Apache Maven

If it is not finding the mvn command then I suspect that it has removed the directory mvn is in from the path variable. Run Terminal.app and type
echo $PATH
See if this includes the directory for mvn. You could try modifying your /etc/paths file (system wide) or for just a single user account the file to create/modify is
~/.profile
It is generally best not to modify the system wide one if you don't need to.
Reinstalling mvn might also be a solution and you could take the opportunity to update your mvn at the same time.

I'm also having this problem. Error text from my system below. It's a fresh install of Windows 8, joined to our domain and updated. VMWare Tools was installed automaticaly, but not even antivirus aside from that. It seems I can use most of the

Anyone make any progress?
