Beginner trying to get my beans to work with jsp on tomcat

Please help me open my eyes!
I know this is a stupid oversight on my part, but I've been working for days on getting other things to work on my tomcat server, so I'm out of ideas on this one.
I've followed all the tomcat docs instructions on where to put my jsp and bean files and set my classpath to where my beans are located. jsps work fine for me but when I try to run this jsp that uses my CalcBean, I get this and similar internal server errors:
org.apache.jasper.JasperException: Unable to compile class for JSP
An error occurred at line: 1 in the jsp file: /jsp/calc/calculate.jsp
Generated servlet error:
C:\jakarta-tomcat-4.0\work\Standalone\localhost\research\jsp\calc\calculate$jsp.java:56: Class org.apache.jsp.CalcBean not found.
CalcBean calc = null;
^
Do I need to register my bean somewhere like web.xml?
Thanks so much in advance for any help!!

  • Trying to get wireless remote to work with Flash Presentation... HELP!!!

    I know almost nothing about Flash or Powerpoint.  I was given a Flash presentation I need that I'd like to show at meetings using my new wireless remote, but I can't get it to move forward & backward between slides (works fine using arrow keys on the laptop keyboard - Windows XP Pro).  The remote works fine with Powerpoint presentations, so I know the remote is ok.  Is there some setting/command I need to allow my Flash presentation to work with my remote, or do I need a special remote?  I already talked to the remote tech support (Keyspan/TrippLite) and they were totally unfamiliar wirh Flash and simply said that their unit works with Powerpoint as advertised, which was true, but they couldn't help me with Flash presentations.  Can anyone out there help me??  Thanks very much!

    Hi, and thanks so much for responding!  I have the Keyspan PR-EZ1 and I don't think it allows me to "map" keys since when I called their tech support, they didn't mention that as an option.  I'm really new at this, but I just noticed - as I was sitting right here on my browser earlier, I pressed the remote's slide-changing keys and my web page scrolled up and down!  Just now I tried it and my insertion point cursor moved up and down!  So I guess these buttons must be "mapped" to the up and down arrows.  How nice it would be if I could somehow figure out how to switch them to the left and right arrows.  A colleague of mine told me just an hour or so ago that when she bought her Logitech wireless remote, it had the same problem with Flash presentations.  But one day, out of the blue, it "fixed" itself and now does Flash fine.  (I didn't ask her if it still does Powerpoint though.)  She has no idea how or why and doesn't care.  Her remote is a discontinued model though (sigh).  Anyway, maybe it'll be worth my while to make another call to tech support and ask about key mapping.  Maybe a more advanced model might allow this function.  Thanks for the spark!

    Sounds like you actually have a 1st generation as those cannot update beyond iOS 3.1.3.

    mono 8 bit 8k is 64kbps, yes. 8 bits times 8,000 = 64,000 = 64k bits/sec.
    And yes I think that's a typo - there's no such thing as 'Mone' that I've ever heard of...
    But you might want to check to find out if this is a mu-law non-linear format, possibly - there are several ways that 8 bit 8k wav files can be encoded, and typically phone systems don't use linear ones. If you have a log-in to Zultys' user-base system they have an FAQ there, I believe - the answer might be in that, and it won't cost $500.

  • I am trying to get my printer to work.

    I am trying to get my printer to work. It is a Canon MP240, it does not show up in the printers menu. Though it is plugged in via USB.

    This printer does have a driver available via Software Update, meaning that when you connect the printer to the Mac via USB cable the driver should be downloaded and installed automatically for you. Of course this will not occur if the Mac cannot detect the printer at the end of the cable. So if you open Print & Scan, select to Add and the MP240 is not shown in the Default Add Printer view then there could be a problem with the USB cable or with the printer.
    To double-check if the printer can be seen by the Mac, open System Information and under the Hardware entry in the sidebar, select USB. Then in the top right pane you will see all the USB connections on your Mac and what is currently connected to them. If the MP240 is not shown, then try moving the cable to a different USB port on the Mac. And don't use a USB hub or the USB port on the keyboard. If moving doesn't help the printer appear under one of the USB busses, then try a different USB cable. If that still doesn't help, turn off the power to the printer and unplug the power cord for 10 minutes before reconnecting and turning it back on.

  • Can't get 'clamshell' mode to work with Dell 2408

    I have been trying to get my Dell 2408 working in clamshell mode without any success. I have a USB keyboard, USB mouse, power adapter and monitor via DVI plugged in. I switch the display type to mirror, close the lid, wait for it to sleep, then wake it again by pressing a key on the keyboard.
    The computer wakes, the external monitor flashes but at the incorrect resolution (1200 X 800 instead of 1920 X 1200) then goes back to sleep. This will repeat over and over again until I open the lid of the macbook. I can occasionally get the macbook to wake and display on the eternal monitor but this is very rare, and when it does I get some wired artifacts.
    What's really puzzling is that the monitor works flawlessly in extended desktop mode, and works perfectly with other non mac computers. I took the macbook to the Genius Bar, hooked it up to the apple cinema displays and i didn't get the same problem! Grrr....
    So I just don't get it, both the computer and display seemingly work fine independently from one another, work fine in extended mode, yet in clamshell mode have some fairly major issues.
    Anyone have any ideas?

    My dell 2408 arrived today and I'm having exactly the same problem.I cant get it to go into clamshell mode. I lie, I got it to go into clamshell mode once. I don't know what I did. But it certainly isn't willing to go into clamshell mode again any time soon.

  • How do you get Oracle 8i to work with j2sdkee 1.3 B

    I had the j2sdkee1.2.1 working with Oracle 8i and I had the following line in the ~conifg/default.properties files
    Here's what worked:
    jdbcDatasources=jdbc/EstoreDB|jdbc:oracle:thin:@localhost:1521:ORCL|jdbc/InventoryDB|jdbc:oracle:thin:@localhost:1521:ORCL|jdbc/jcampDB|jdbc:oracle:thin:@localhost:1521:ORCL
    In the j2sdkee1.3 beta 2, the resource configuration file format seem to have changed and I am not sure how to get oracle to work. I have tried modifying the new format but it does not seem to work. Can anyone tell me where set drivers for Oracle 8i or any place I can look to figure how to.
    jdbcDataSource.5.name=jdbc/Oracle
    jdbcDataSource.5.url=jdbc:oracle:thin:rmi:??;create=true
    jdbcDriver.0.name=COM.cloudscape.core.RmiJdbcDriver
    jdbcXADataSource.0.name=jdbc/XACloudscape
    jdbcXADataSource.0.classname=COM.cloudscape.core.RemoteXaDataSource

    jdbcXADataSource.0.dbuser=
    jdbcXADataSource.0.prop.createDatabase=create
    jdbcXADataSource.0.prop.databaseName=CloudscapeDB
    ==============
    Any pointers on how to get Oracle 8i to work with j2sdkee1.3 b2 will be appreciated. thanks.
    --pvt

    You are right. It seems the format has changed.
    However, now there is and admin tool that comes with J2EE SDK 1.3 Now you don't have to touch the config file by hand.
    You can use this tool to get the configuration done.
    To add JDBC driver the command is...
    j2eeadmin -addJdbcDriver oracle.jdbc.driver.OracleDriver
    and to add a data source the command is...
    j2eeadmin -addJdbcDatasource jdbc/Oracle jdbc:oracle:thin@rtc:1521:acct
    Read details about this and other configuration you can do using this toll in the file %J2EE_HOME%/doc/release/ConfigGuide.html

  • Satellite P300-150 PSPC4E: Cannot get Express Card slot working with XP

    Hello.
    I have downgraded to XP on my machine and unfortunetly I am unable to get the Express card slot to work.
    The Intel chipset drivers on the Toshiba site haven't dont anything.
    I am trying to get an eSata port working via the express card like I did with Vista but no joy at all.
    Any ideas?
    Regards
    Rob

    Go to Device Manager and check if the express card is installed properly, or if its reporting an error.
    You should update the BIOS to the latest version. BIOS updates can sometimes fix problems like this.
    And ensure you have XP Service Pack 2 or 3 installed.

  • How can I get my iMac to work with scanners?

    How can I get my iMac to work with scanners? The scanners scan just fine, but not to my iMac. I've tried Epson and HP all-in-ones; it makes no diffference. I'm becoming extremely displeased, but don't know at whom I should be displeased, the printer guys or Apple. Help?

    My Epson is able to do scans using Image Capture without any problems at all.

  • I am trying to get an AP to associate with a wireless Controller but keep getting this error message (%CAPWAP-3-ERRORLOG:Could not resovle CISCO-CAPWAP-CONTRPLLER)

    I am trying to get an AP to associate with a wireless Controller but keep getting this error message (%CAPWAP-3-ERRORLOG:Could not resovle CISCO-CAPWAP-CONTRPLLER)
    I can ping through to the WLC and the AP.

    Thanks a lot Loe for the Feedback. The issue was not my configuration but rather the type of Wireless LAN controller I have, the WLC does not support my  AP's. I have a Cisco 520 series WLC and got to know they only work with the 500 series AP's. my AP's are 1130 series meaning i have to get another controller or change the APs.
    thanks once again..

  • Why can't I get the average function work with empty cells?

    Why can't I get the average function work with empty cells?

    The thing that I am having a problem with is that I made a different form that calculates the average no matter how may of the cells have numbers or not and I didn't use an if function.  I have tried with this other form and and it calulates as if all the cells where being used.  I am using the [*] in both instances but it only works in the one I did earlier.

  • Getting RIFT game to work with Crossover?

    I'm currently trying to get this game to work.  It will boot up, load fine and everytime I start the game, it says I should get updated drivers.  Has anyone else had this and found a way to update them?  I currently have this configuration:
    OS = mac OS X10.6.7
    memory = 4 GB DDR3 1067 MHz (2 2GB sticks)
    Graphics = Nvidia GeForce 9600M GT*
    processor = Intel Core 2 Duo 2.8 GHz
    *when graphics are turned off I have the GeForce 9400M graphics. 
    The game will play on about half and hour to an hour then the screen will freeze.  It freezes but not entirely.  My character will not move, but if i hit the directional pad, his weapons move as if he is (when he really isn't).  if that makes any sense at all.  it will happen when I'm just walking around and it happens when I'm in battle.  When in battle I can still hear the abilities/talents working and the creature die.  It has to be this driver because I can't think of anything else but that.  Its the only thing keeping this game from functioning properly.  I have contacted codeweavers to see what they recommend or even if they have a fix, and I'm anxiously awaiting a reply. 
    I don't care so much about the visuals as I do being able to play the game.  I was told it may be my drivers, and I don't think there are any available for mac, unless you know how to go in and change some coding (which I'm not about to mess up my entire computer trying to follow the instructions in German).  I don't want to install windows because I switched to mac and don't wanna go back.  Windows = problems in my book.  If anyone is familiar with this problem and can help out I would appreciate it.
    Thanks

    Have you tried searching/asking in the crossover forums?
