Java related question

my wife is taking online classes and has a MacBook...there's a class she takes that has interactive graphs...the graphs will not load properly and says to download the latest version of Java...we've done the software update and her MacBook is up to date...still the graph will not load.
any suggestions would be helpful.

Hi Mayot,
Is it a Blackboard-like application? The web application is properly looking for the Windows Java version (performing a browser check). Apple distributes the Java updates via Software Update so if you're all up-to-date then you've got the latest greatest for Mac OS X.
I take it you can't access the website via Safari or Firefox?
There's little you can do if the website isn't compatible. Have you reached out to the school that hosts the website regarding any Mac assistance?

  • Not a java related question

    First of all I am sorry as this is a general work ethics quetion and not a java question, so please donot flame me. I am a fresh graduate and recently started working at a financial firm. Now I have one associate who has been pretty hostile to me from the very first day. I initially observed that this gentleman was not following the java best practices and was in a habbit of coding bad, e.g. excessively accessing the databases from withing jsp's, as a matter of fact putting all the code in jsp's and not even having a java class let alone following MVC architecture. In a code review once I pointed it out(in person and not in front of the whole group) he got even more hostile. Currently I have been assigned a task to set up standards for java and put some docs in place. Once I put a doc together and mailed it to my co workers for advice he mails me that its just an excerpt from various already existing websites. Now yes once you set up a standards doc you are not going to write your own but basically adapt some and would use those existing already on the web.
    Now what am I supposed to do. involve my manager, talk to my peers or just ignore him? I am sure he is going to continue with the gossip. I am new to office and coorporate environment and am sure some of you must have faced similar problems. How would you advise to handle.
    advice greatly appreciated.

    Just tell him exactly what you told us. You don't have anything to hide, and you only did what any of us would do (grab already existing standards and tailor them to our needs). If he can't accept your answer, then too bad for him.
    When it comes to reviewing his code, it will be measured against the new standards. Be honest when these reviews come about, but do not be derogatory (i.e. "This code sucks!" <- don't say that).
    Lastly, this is very weak gossip if that is what he is doing. And you can squash him like a bug by being honest with how you approached the problem. I can see a conversation going like this:
    Idiot: "Hey, you... did you hear that so-and-so just copied stuff off of the internet and turned it in as work?!!!"
    Co-worker: "Oh, you mean the new Java standards that cirmo put together. Well, from what he said, he didn't want to reinvent the wheel and there are tons of standards to use as templates out there. So, I don't see what he did wrong."
    (BTW, he is probably being critical of you because he knows that his code blows chunks.)

  • Two related questions:  ColdFusion 10/Java applications and J2EE supported servers

    I have two related questions:
    1.  CF10 and integration with Java Web applications
    We have a couple of Java applications running on JRun and interfacing with CF9 applications.  The JRun clusters were created through the JRun Admin and, apart from lack of Axis 2.0 support, have served us well for years now.  And, as would be the case, the ColdFusion9/Java/Flash application is a critical public-facing application that the business uses for bidding on projects.
    It appears that with ColdFusion 10 on Tomcat, we will not be able to run those Java applications on a Tomcat-CF10 JVM cluster.  Is this correct?  IF so, what are our options? 
    2.  J2EE Application Servers supported by Adobe for CF10
    Which of these is correct?
    A.  This URL (http://www.adobe.com/products/coldfusion-enterprise/faq.html) states "ColdFusion 10 supports IBM® WebSphere, Oracle® WebLogic, Adobe JRun, Apache Tomcat, and JBoss."
    B.  This URL (http://wwwimages.adobe.com/www.adobe.com/content/dam/Adobe/en/products/coldfusion/pdfs/cf1 0/coldfusion10-support-matrix.pdf) states:
    "J2EE application servers: WebLogic Server 10.3, 11.1, WebSphere Application Server 7, ND 7 JBoss 5.1, 6.0, 7.1.0"
    I *think* "A" above is wrong re. support for Adobe JRun.  It does not specify a version of Apache Tomcat unless it is simply referring to the custom version the comes with CF10.
    Option "B" above shows no support of Adobe JRun or 'standard' Apache Tomcat.
    Thanks,
    Scott

    Question 1 above was answered:  "No support for Java web applications under CF10's custom version of Tomcat"
    Question 2:  No answer yet:  Is Apache Tomcat (NOT Adobe's customized version) supported for CF10 J2EE deployment?  I do not see any installation instructions on how to install CF10 on Apache Tomcat 6 or 7.
    Is anybody using Apache Tomcat as their J2EE app servers and, again, NOT Adobe's customized/limited version? 
    Thanks,
    Scott

  • Deploying multiple beans & support classes, related questions

    I have an application that I'm trying to deploy to the latest JServer with Oracle 8i 8.1.6 on Windows 2000. We used JDeveloper to write the code and to deploy the EJBs. I have some questions and it'd be great if someone can answer them.
    All documentation seem to indicate that beans must be deployed one at a time. Is this the case? If not, how?
    If so, what is the "correct" way to deploy helper classes which are used by more than one bean?
    Is there always only one instance of a class in the database, even though I might deploy the same helper class with different beans? If not, is there any mechanism to ensure consistency?
    Can I just update a helper class in the database?
    How do I see what classes are in the database? How do I manipulate them (e.g. delete, change, add, view size) ?
    Is there an easy way to "clean out" the database of all classes, so as to start anew?
    null

    The Java-related documentation was that I was reading. I have a followup question. Is it possible for me to simply deploy some beans without regard for all the helper classes, then at a later point do a load java on all classes that I expect to use, and have it all work?
    Thanks. You've been great help.
    <BLOCKQUOTE><font size="1" face="Verdana, Arial">quote:</font><HR>Originally posted by JDev Team (Laura):
    Hi Gerald,
    I will take a stab at answering your questions:
    1. Are you talking about the JDeveloper doc, or the Oracle8i EJB doc?
    2. When you create the Deployment Profile in JDeveloper using the Deployment Profile wizard, any classes your EJB depends on should get included in the deployment archive by the dependency analyzer. You can see the contents of what will be deployed by selecting the Preview button on the Sources page of the wizard.
    If you want to explictly EXCLUDE a helper class because it has already been deployed with another bean, you can choose the Advanced button. Select one of the Library, archive, class pages on the Advanced dialog, and add the class to the Exclude list. Select OK, then check the Preview button again to make sure it was excluded.
    If you are deploying a number of beans that user the same helper classes, the helper classes will get deployed with the first bean, and on subsequent deployments, the process will detect that the helper class has already been deployed and will check to see if it has changed since the last deployment. I believe it uses a timestamp comparison for this, but I'm not positive. If it detects the source and target are the same, it won't redeploy the class.
    If you just want to update a helper class for the EJB, you can use the Java Stored Procedure deployment in the Deployment Profile Wizard, include the helper class in the deployment archive, and do not publish anything.
    You can use the Database Browser in JDeveloper to see what deployed Java Classes, and EJBs are stored in your database. Double-click on the IIOP connection you used to deploy the EJBs (under the Connections node in the Navigator). This will display the Database Browser. Expand the appropriate nodes to view the deployed objects.
    To see deployed Java Classes, double-click on a JDBC connection and expand the Schema node and then the Deployed Java Classes node.
    Many operations are available from the context menus in the Database Browser, including Drop. Others you will have to perform from SQL*Plus or the command line. See the Oracle8i Java Developer's Guide for more information on SQL commands and command line syntax for altering Java objects in the database. This doc, and the EJB and CORBA Developer's Guide are available online from OTN on the Doc pages.
    You can use dropjava to drop all classes that were deployed in a given deployment archive by specifying the name of the jar file used during deployment. Again, see the Java Developer's Guide for the syntax.<HR></BLOCKQUOTE>

  • Slow Performance - Java Related?

    This is an old box that I bought used recently, but the system install is recent. The system performs very slowly - about 50% of the speed of comparable Mac's in the XBench database. If I use Xupport to manully run "All" of the system maintenance crons I get some improvement, but it quickly goes back to being slow.
    Looking at my logs I have a "boat load" of Java errors under CrashReporter; there will be a string of "JavaNativeCrash_pidXXX.log" entries - many of them, as follows:
    An unexpected exception has been detected in native code outside the VM.
    Unexpected Signal : Bus Error occurred at PC=0x908611EC
    Function=[Unknown.]
    Library=/usr/lib/libobjc.A.dylib
    NOTE: We are unable to locate the function name symbol for the error
    just occurred. Please refer to release documentation for possible
    reason and solutions.
    Many of the line entries that follow, but not all of them, refer to SargentD2OL, which is a Java app, which I installed, but it did not work properly so I removed it. Yet I continue to get Java errors that refer to this now non-existant app.
    I have read that Java apps use a lot of resources, and that D2OL in particular uses a lot of resources. Can my slow performance problem be Java related? If so, any idea of how I can fix this problem?

    Sorry to take so long to respond, but other issues in life have demanded my attention.
    None of the solutions given have had any affect. My Java folder has both a 1.3.1 and a 1.4.2 app - the Java Update 2 will not reinstall because it sees an up-to-date app in the folder. But reading the update file it says the older Java will be removed - but it is still there. Problem?
    On XBench the system scores a 9 to 10, while similar boxes on the XBench database score around 18 to 20. My cpu, memory, and video scores are very low. The HD through-put scores are the only ones that are normal. TechTool Pro 4 finds no problems. I have removed the memory sticks one at a time and retested after each cycle - no difference.
    I have two drives, each with a 10.3.9 install. One works fine, scores around a 17 on XBench, the other scores a 9 to 10. So it appears to be a software problem. The slower install is a drive from a iMac G3 that has been moved to the G4 - are there issues with this?
    My favored drive is the prior G3 one (newer and faster than the other drive that system tests faster in XBench) - it has my profile and all my info on it. It worked fine in the G3 - no problems.
    Thanks for the help,

  • I want to check all functions of PCI 6534.I have read the user manual..I have some memory related questions.​Please help me for that.

    I want to check all functions of PCI 6534.I have read the user manual..I have some memory related questions.Please help me for that.
    1.)If i am using the continuous output mode.and the size of generated data is less than 32 MB.If i want to preload the memory,what should i do?I want that first of all i load all my data to onboard memory & then i want to make start the transfer between 6534 & peripheral.Is it possible?As per me it should be.Plz tell me how should i do this?I think that in normal procedure the transfer between 6534-peripheral & outputting data from pc buffer to onboard memory works parallely.But i don't want this.Is it poss
    ible?
    (2).Similarly in finite input operation(pattern I/O) is it possible to preload the memory and then i read it?Because i think that the PC memory will be loaded automatically when 6534 acquires the data and then when we use DIO read vi the pc buffer data will be transferred to application buffer.If this is true,i do not want this.Is it possible?
    (3) One more question is there if i am using normal operation onboard memory will be used bydefault right?Now if i want to use DMA and if i have data of 512 bytes to acquire.How will it work and how should i do it?Please tell me the sequence of operations.As per my knowledge in normal DMA operation we have 32 Bytes FIFO is there so after acquisition of 32 bytes only i can read it.How it will known to me that 32 bytes acquisition is complete?Next,If i want to acquire each byte separately using DMA interrupts what should i do?Provide me the name of sourse from which i can get details about onboard memory & DMA process of 6534 specifically
    (4).In 6534 pattern Input mode,if i want to but only 10 bits of data.and i don't want to waste any data line what should i do?

    Hi Vishal,
    I'll try to answer your questions as best I can.
    1) It is definitely possible to preload data to the 32MB memory (per group) and start the acquisition after you have preloaded the memory. There are example programs on ni.com/support under Example Code for pattern generation and the 6534 that demonstrate which functions to use for this. Also, if your PC memory buffer is less than 32MB, it will automatically be loaded to the card. If you are in continuous mode however, you can choose to loop using the on-board memory or you can constantly be reading the PC memory buffer as you update it with your application environment.
    2) Yes, your data will automatically be loaded into the card's onboard memory. It will however be transferred as quickly as possible to the DMA FIFO on the card and then transferred to the PC memory buffer through DMA. It is not going to wait until the whole onboard memory is filled before it transfers. It will transfer throughout the acquisition process.
    3) Vishal, searching the example programs will give you many of the details of programming this type of application. I don't know you application software so I can't give you the exact functions but it is easiest to look at the examples on the net (or the shipping examples with your software). Now if you are acquiring 512 bytes of data, you will start to fill your onboard memory and at the same time, data will be sent to the DMA FIFO. When the FIFO is ready to send data to the PC memory buffer, it will (the exact algorithm is dependent on many things regarding how large the DMA packet is etc.).
    4) If I understand you correctly, you want to know if you waste the other 6 bits if you only need to acquire on 10 lines. The answer to this is Yes. Although you are only acquiring 10 bits, it is acquired as a complete word (16bits) and packed and sent using DMA. You application software (NI-DAQ driver) will filter out the last 6 bits of non-data.
    Hope that answers your questions. Once again, the example code on the NI site is a great place to start this type of project. Have a good day.

  • Garbled Text/Odd font in Safari since updating to Tiger.  Java related?

    I seem to be having a problem with Safari since I updated to Tiger.
    I'm running Safari 2.0.3, and have been encountering problems with garbled text in a strange font when Safari loads certain pages. The text often overlaps making it impossible to read.
    A friend thinks it might be Java related. I've tried clearing the cache and resetting Java, but it hasn't helped.
    Here's a screenshot example: http://i8.photobucket.com/albums/a2/tashamay/Picture2.jpg
    On the Petfinder.com page specifically, if I go directly to their home site everything is fine, but once I try and search the results come up all messed up.
    I also have a problem with it when I try andl log into gmail. "Loading" comes up on the screen in the garbled text font as if it's trying to load an applet, but nothing happens. I eventually get the spinning rainbow of death and have to force quit.
    Any ideas?

    Hello tashamay:
    I am not an expert in font issues, but you may have corrupt fonts. Open "font book.' Select all and run resolve duplicates. Then select all and run validate fonts. I also have read that Helvetica fractional fonts have caused some rendering problems.
    I would also clear the Safari cache again.

  • JAVA beans and JAVA related services require Oracle client to be installed?

    Can you please advice whether an application server that make use of JAVA beans and JAVA related services require Oracle client to be installed?

  • Visio like object drawing in Java - newbie question

    Hi all,
    Although a reasonably experienced java programmer I am new to the world of 2D graphics.
    I am contemplating writing a tool which includes a diagramming capability for displaying computer systems and interactions between them.
    I guess this would not be a million miles from what a UML diagramming tool does, but it would definitely have some differences.
    So, for example, in this tool a user would be able to:
    Define a computer system and allocate an icon for it.
    Drag that system icon onto a diagram.
    Draw lines between systems and to represent interactions and define what those interactions were.
    Does anyone know if there are any Java API's or tools out there which could get me started?
    Thanks in advance, Robin.

    Go fly a kite, Troll. OP said he was new and wanted to know which Java API's to use for 2D graphics. Moreover, there are no Java-related API's with diagramming capability. He can Google for that anyway.He's not new to java as he has stated that he is a "reasonably experienced java programmer". He also knows that he will probably need Java2D else he wouldn't be in this forum. If he is reasonably experienced, there's no doubt that he knows about Swing and how it can be used to create GUIs.
    To the OP, you could try to roll your own Visio like flowcharting program through Java2D and Swing, but you will probably get up and running faster if you use tools already created for this purpose. One such is JGraph ^1^. There are probably others as well.

  • Quick SQL-related question

    With MSAccess, my understanding is that if you have a string with length under 255 it's type is TEXT, and over 255 it's MEMO... is this right?
    My real question is about the CREATE TABLE string, which might look something like this for a shorter bit of text:
    CREATE TABLE MyTable ([MyColumn] TEXT(30) NOT NULL, etc.)
    But what does this string look like if the column will hold strings of text longer than 255? Do I only specify the size like TEXT(400), or do I list the type like MEMO(400) or what?
    I realize that this isn't really a Java focused question, but I'm hoping it's close enough. After all, the app that I'm working on is in Java. I haven't had much luck finding the clarification I need by just googleing this. Thanks for the help.

    Okay, Ceci, I don't know as much about this stuff as
    you obviously do, so I'm really sorry I offended you
    with my newbie faux pas. Do you realize that in the
    time it took you to rip on me you could have already
    answered the question? Thanks for the sentiment.I answered it the best I could: write a small program and try it.
    With MSAccess, my understanding is that if you have a string with length under
    255 it's type is TEXT, and over 255 it's MEMO... is this right?String: max. 255 chars
    Memo: max 64000 chars.
    Sez the Access help.
    But what does this string look like if the column will hold strings of text longer
    than 255? Try it. Might puke, might truncate the String, might autoconvert. I don't know. You'll see.
    Do I only specify the size like TEXT(400), or do I list the type like MEMO(400) or what?If you expect it to be > 255 chars, why not simply define the field as Memo right away? I doubt you can write a Memo to a textfield.

    I will use the program with photo detector to test
    the response time of the LCD screenWhy Java?I second that. With a test like that, you want to reduce the experiment down to a single variable, in this case the lcd response time. Using a java program to feed the monitor input introduces a second variable, the response time of the program. The java program's timer may not be exact, the components may not be repainted completely quickly enough, etc. If this is just for your own amusement, maybe that doesn't matter, but if you want your results to have any reliability, you'll need a more accurate and controllable input source.

  • Deleted all Java-related files from system

    Hello there, community!
    This issue will make me look like a dummy, but here it goes. Basically it is what I did yesterday, I erased all Java-related files from my computer for hideous reasons, now before considering a reinstall, I'd like to know whether there is a solution to this problem. My recovery partition still has Mavericks installed, which is weird, seeing as I am on Yosemite already.
    Basically most apps won't start, and that includes Finder, App Store and every other major app/resource I might need to use for a recovery.
    I tried to re-download Java from Oracle website and JDK, but .dmg files won't run either.
    I'm trying to look for as many solutions as possible before I do a recovery, because again, I don't have a Time Machine, and hope there will be a solution as I have lots of work to finish.
    Any type of help will be welcome!
