  • How can I retrieve data from a Western Digital Passport External Disk which is not getting recognized but getting shown as healthy in Device manager

    - by Rabimba Karanjai
    When I plug in this external harddisk It is not getting shown in the My Computer. But it gets shown perfectly well in the Device Manager When I go into the Computer Administrative panel and into the disk manager it asks me to initialize the disk Now when I try to initialize it, regardless of the method I try it shows me an error "Incorrect Function" As you can see windows tells me it is working properly. Is there anyway I can retrieve data from this?/access it? I have googled and it seems to be a frequent problem with WD drives. Anyone has any solutions on how I can get the data back?

  • Should I use VFAT or ext3 for a 1Tb external usb hard drive?

    - by ihuston
    I have a 1 Tb USB external hard drive which I want to use to backup data from my home and office desktops (both running Linux). Should I format the drive (possibly split into a few partitions) as vfat or ext3? I don't anticipate using the drive with Windows very often so this is not a primary concern. The main thing holding me back from just using ext3 is the problems you can have when two different users (home and work accounts) try to access each others data. Is there any way to mount an ext3 drive with user id mapping?

  • Viruses on external hard drive -- how to clean files?

    - by Jade
    Last year my Dell laptop caught some pretty nasty viruses; I saved all my important stuff on an external hard drive. In an unrelated turn of events, I replaced my Dell with a Mac and have been able to retrieve data from the hard drive without trouble. The problem is, I'm sure the hard drive has a few lingering viruses and I really don't want to infect any more PCs with it. I was planning to reformat it anyway, but I'd like to be able to save my files. Would transferring those files to my Mac and then scanning them for Windows viruses before throwing them back onto the newly reformatted hard drive be enough?

  • How can I copy files to an external drive and verify their integrity in OS X?

    - by jedavis
    I'm moving large amounts of data from one external drive to another larger one. The files are important and the smaller drives need to be cleared and reused (HD camera). Is there some utility for moving files and verifying their integrity? I've been using this command find . -type f -exec md5 '{}' \; > md5list.txt in the terminal to create a list of MD5s for each file then using diff to compare the two. However, I am moving 320GB at a time, which takes a while by itself. Computing the checksums takes another hour or so. It would be much more efficient to do this on the fly, during the copy. I'm just hoping someone has already written the software...

  • Reducing storage cost by moving old files to external USB HDDs. Your thoughts?

    - by cparker4486
    I've got about 300GB of pictures and marketing data that is rarely accessed and I'd like to get it off my main storage. I was thinking to simply add two external USB HDDs to the server and move all the files to one of the drives. The second drive would be the backup destination for the first drive. I'm working with Server 2003 R2 SP2. This will help me free a good amount of space on my main storage as well as reduce the complexity, backup window, and usage of my backups to tape.

  • What laptops can run an external 27" or 30" screen at 2560x1600 native resolution? [closed]

    - by Moin Zaman
    SU Folks, What laptops do you know off that can run a 27" or 30" external monitor as a secondary display (Extending desktop onto second screen, without switching off the laptop's own built in screen) at the screens native resolution of 2560x1600. I'm not interested docks or USB video adapters etc. Just via the laptop's built in display ports. List the port used and cable as well if possible. Reference links / posts that confirm it are an added bonus. I'm hoping people who've tried it themselves and / or confirmed it can list specific models of laptops so we can build up a good list.

  • I want to reformat my external hard disk but disk utility said it could not be unmounted

    - by Faith
    Hi I wanted to reformat my HP 500GB hard disk to MS DOS (FAT) by using Disk Utility but Disk Utility kept saying that the hard disk cannot be unmounted. I tried googling it but nothing seems to answer my question. I'm not trying to reformat the hard disk in my Mac but my external hard disk! I usually format my hard disks to clear the documents I no longer need. And I'll change it to ExFat but currently, whenever I plug in my hard disk on Windows, the whole system just hangs there. Can someone help??

  • fmod VS2008 unresolved externals in dependant project

    - by Tom J Nowell
    Im currently trying to use the latest stable fmod ex in my project. I have a main executable in a project called engine4, and a project named DX9Platform in the solution as well which ti depends on. All the fmod code is in this DX9Platform project, which generates a lib file. DX9Platform includes fmodex_vc.lib and builds fine. However buildign Engien4 results in unresolved external symbol messages referencing files that use fmod in the DX9Platform project I have tried adding fmodex_vc.lib to the Engine4 project, with no success, how do I fix this?

  • JSON.parse string with quotes

    - by mjsilva
    Hi, I've this: JSON.parse('{"130.00000001":{"p_cod":"130.00000001","value":"130.00000001 HDD Upgrade to 2x 250GB HDD 2.5\" SATA2 7200rpm"}}'); http://www.jsonlint.com/ says it's perfectly valid json. But on execution I have a JSON.parse error. But, if I change my code to: JSON.parse('{"130.00000001":{"p_cod":"130.00000001","value":"130.00000001 HDD Upgrade to 2x 250GB HDD 2.5\\" SATA2 7200rpm"}}'); (note the double backslash) It works, but now jsonlint gives me invalid json :/ Can someone help to understand this behavior?

  • How do I solve an unresolved external when using C++ Builder packages?

    - by David M
    I'm experimenting with reconfiguring my application to make heaving use of packages. Both I and another developer running a similar experiment are running into a bit of trouble when linking using several different packages. We're probably both doing something wrong, but goodness knows what :) The situation is this: The first package, PackageA.bpl, contains C++ class FooA. The class is declared with the PACKAGE directive. The second package, PackageB.bpl, contains a class inheriting from FooA, called FooB. It includes FooB.h, and the package is built using runtime packages, and links to PackageA by adding a reference to PackageA.bpi. When building PackageB, it compiles fine but linking fails with a number of unresolved externals, the first few of which are: [ILINK32 Error] Error: Unresolved external '__tpdsc__ FooA' referenced from C:\blah\FooB.OBJ [ILINK32 Error] Error: Unresolved external 'FooA::' referenced from C:\blah\FooB.OBJ [ILINK32 Error] Error: Unresolved external '__fastcall FooA::~FooA()' referenced from blah\FooB.OBJ etc. Running TDump on PackageA.bpl shows: Exports from PackageA.bpl 14 exported name(s), 14 export addresse(s). Ordinal base is 1. Sorted by Name: RVA Ord. Hint Name -------- ---- ---- ---- 00002A0C 8 0000 __tpdsc__ FooA 00002AD8 10 0001 __linkproc__ FooA::Finalize 00002AC8 9 0002 __linkproc__ FooA::Initialize 00002E4C 12 0003 __linkproc__ PackageA::Finalize 00002E3C 11 0004 __linkproc__ PackageA::Initialize 00006510 14 0007 FooA:: 00002860 5 0008 FooA::FooA(FooA&) 000027E4 4 0009 FooA::FooA() 00002770 3 000A __fastcall FooA::~FooA() 000028DC 6 000B __fastcall FooA::Method1() const 000028F4 7 000C __fastcall FooA::Method2() const 00001375 2 000D Finalize 00001368 1 000E Initialize 0000610C 13 000F ___CPPdebugHook So the class definitely seems to be exported and available to link. I can see entries for the specific things ILink32 says it's looking for and not finding. Running TDump on the BPI file shows similar entries. Other info The class does descend from TObject, though originally before refactoring into packages it was a normal C++ class. (More detail below. It seems "safer" using VCL-style classes when trying to solve problems with a very Delphi-ish thing like this anyway. Changing this only changes the order of unresolved externals to first not find Method1 and Method2, then others.) Declaration for FooA: class PACKAGE FooA: public TObject { public: FooA(); virtual __fastcall ~FooA(); FooA(const FooA&); virtual __fastcall long Method1() const; virtual __fastcall long Method2() const; }; and FooB: class FooB: public FooA { public: FooB(); virtual __fastcall ~FooB(); ... other methods... }; All methods definitely are implemented in the .cpp files, so it's not not finding them because they don't exist! The .cpp files also contain #pragma package(smart_init) near the top, under the includes. Questions that might help... Are packages reliable using C++, or are they only useable with Delphi code? Is linking to the first package by adding a reference to its BPI correct - is that how you're supposed to do it? I could use a LIB but it seems to make the second package much larger, and I suspect it's statically linking in the contents of the first. Can we use the PACKAGE directive only on TObject-derived classes? There is no compiler warning using it on standard C++ classes. Is splitting code into packages the best way to achieve the goal of isolating code and communicating through defined layers / interfaces? I've been investigating this path because it seems to be the C++Builder / Delphi Way, and if it worked it looks attractive. But are there better alternatives? I'm very new to using packages and have only known about them through using components before. Any general words of advice would be great! We're using C++Builder 2010. I've fabricated the class and method names in the above code examples, but other than that the details are exactly what we're seeing. Cheers, David

  • Laptop Asus P50IJ with Intel 4500M GMA output going to a Dell 1907FP external monitor will not allow

    - by ProfessionalAmateur
    Hello - I just purchased an Asus P50IJ-X2 laptop which has a Intel GMA 4500M video card running Windows7. At work I output this laptop to a Dell 1907FP LCD which has a maximum resolution of 1280x1024. Not matter what I do the Windows will not allow the laptop to set a resolution higher than 1024x768 to this LCD monitor. Ive even gone to the extent of downloading PowerStrip (I'd post a link but Im new and can only enter 1 url, if you google for powerstrip its the first option) to create a custom driver for my monitor thinking Windows was having a hard time seeing the available resolutions it would accept. However, powerstrip read the registery and properly sees the monitor and what its capable of so Im now at a complete loss as to why Windows7 will not allow me to set/use a 1280x1024 resolution for this external monitor (as my last laptop did running Vista). The Intel documentation (http://software.intel.com/en-us/articles/quick-reference-guide-to-intel-integrated-graphics/) indicates that the GMA 4500M should be able to run up to a 2560x1600 max res. The Dell 1907FP specification states it can run up to a 1280x1024 res. But no matter what the computer will not allow me to set higher than a 1024x768. I'm completely baffled but I would really like to be able to output this laptop to a reasonable resolution, 1024x768 makes me feel like I'm using my mom's computer. Any help would be greatly appreciated! Here are some attached images (I apologize for the links, being new I cannot post images) that should help explain this better: Image 1 - This image is from powerstrip which shows the monitors max accepted resolution and at the top right the max res my PC currently allows. (http://imgur.com/agrno.png) Image 2 - This shows my Windows7 resolution picker. (http://imgur.com/3nv6q.png) Image 3 - The 'List all modes' option taken from the Screen Resolution Advanced Settings List All Modes. (http://imgur.com/AMREh.png) Image 4 - Monitor information from registry read by powerstrip, this shows the laptop is able to read the necessary info from the LCD monitor.

  • Configure one IIS site to handle two separate SSL certificates using external Load Balancing or SSL Acceleration Servers

    - by bmccleary
    I have one web application on our server that needs to be referenced by two different domain names, both of which have their own SSL certificates. The application is exactly the same for both domains, but we have to keep the two domain names for legal reasons. The problem is that, since both domains need to have their own SSL certificate, that inside of our IIS 7.5 configuration we have to have two separate IIS applications (both pointing to the same physical location) with their own unique IP address and SSL certificate installed. Now, I know that, due to the nature of SSL communications, that this is by design and that you can't assign more than one SSL certificate per IP address and domain name. My question is… is there any way around this limitation and keep one web application in IIS and have it service two SSL certificates based on host name? I know that with the basic IIS configuration that this is not possible, but I was thinking that with some sort of combination of external load balancing and/or SSL acceleration servers/services that we could have these servers process the SSL request and leave IIS clean to have one single application. I am not familiar at all with these technologies, hence the reason I am asking if it is theoretically possible. If not, does anyone else know how to achieve this?

  • What are the frequencies of current in computers' external peripheral cables and internal buses?

    - by Tim
    From Wikipedia, three different cases of current frequency are discussed along with the types of cables that are suitable for them: An Extra Ordinary electrical cables suffice to carry low frequency AC, such as mains power, which reverses direction 100 to 120 times per second (cycling 50 to 60 times per second). However, they cannot be used to carry currents in the radio frequency range or higher, which reverse direction millions to billions of times per second, because the energy tends to radiate off the cable as radio waves, causing power losses. Radio frequency currents also tend to reflect from discontinuities in the cable such as connectors, and travel back down the cable toward the source. These reflections act as bottlenecks, preventing the power from reaching the destination. Transmission lines use specialized construction such as precise conductor dimensions and spacing, and impedance matching, to carry electromagnetic signals with minimal reflections and power losses. Types of transmission line include ladder line, coaxial cable, dielectric slabs, stripline, optical fiber, and waveguides. The higher the frequency, the shorter are the waves in a transmission medium. Transmission lines must be used when the frequency is high enough that the wavelength of the waves begins to approach the length of the cable used. To conduct energy at frequencies above the radio range, such as millimeter waves, infrared, and light, the waves become much smaller than the dimensions of the structures used to guide them, so transmission line techniques become inadequate and the methods of optics are used. I wonder what the frequencies are for the currents in computers' external peripheral cables, such as Ethernet cable, USB cable, and in computers' internal buses? Are the cables also made specially for the frequencies? Thanks!

  • Are there compact external USB audio interfaces which are better than a on-board sound?

    - by rumtscho
    I am asking this for a friend. He loves his voice recognition software and dictates a lot of text using a headset. Now he has a new laptop, which only has a combined mic/headphones output, and wanted to buy an adapter. I told him to get an external USB sound interface instead, as the better sound quality will probably increase the hit rate of the voice recognition. He agreed, but when he saw a picture of the SoundBlaster X-Fi, he said that it is way too big, because he wants to carry the thing everywhere. He'd rather have one of these small things which are the size of a flash memory stick, with only one mic and one phones output, period. Now I am not sure whether these mini interfaces would produce a sound better than onboard sound. They all seem to come not from established audio interface manufacturers, but from electronic accessories manufacturers like Speedlink, or just noname brands. Is there a compact audio interface with good A/D quality (it is OK if the price is comparable to that of the bigger interfaces, even if there is no additional functionality like Chinch in-/output etc)?. And if there isn't, will the noname soundcardsticks offer any advantage over a simple adaptor for the onboard sound?

  • How do I Forward root's email to an external email address?

    - by ErebusBat
    I have a small server (Ubuntu 10.04) at my house and I would like to forward root's email to my gmail hosted domain to get security notifications and what not. I ripped everything out and started from scratch and ran into some other issues. I now have sendmail working in the sense that I can mail [email protected] and get the mail. HOWEVER, adding an address to /root/.forward does not actually forward the message. I get the following in my logs: Dec 22 14:04:37 batcave sendmail[4695]: oBML4bAT004695: to=<root@batcave>, ctladdr=aburns (1000/1000), delay=00:00:00, xdelay=00:00:00, mailer=relay, pri=30075, relay=[127.0.0.1] [127.0.0.1], dsn=2.0.0, stat=Sent (oBML4bJ9004696 Message accepted for delivery) Dec 22 14:04:39 batcave sm-mta[4698]: STARTTLS=client, relay=[69.145.248.18], version=TLSv1/SSLv3, verify=FAIL, cipher=DES-CBC3-SHA, bits=168/168 Dec 22 14:04:40 batcave sm-mta[4698]: oBML4bJ9004696: to=<[email protected]>, ctladdr=<[email protected]> (1000/1000), delay=00:00:03, xdelay=00:00:03, mailer=relay, pri=120336, relay=[69.145.248.18] [69.145.248.18], dsn=2.0.0, stat=Sent (OK 01/D4-00853-216621D4) You can see where my local sendmail instance accepts it then hands it off to my ISP, but with the wrong address ([email protected]).

  • How do I mount an external USB hard drive on my Sheevaplug?

    - by James
    I've acquired a Sheevaplug running - I think - Ubuntu. I'd like to mount an external USB hard drive, but I don't know the name of the device that needs mounting. When I list the devices under /dev, a long list is produced. How do I find out which device listed needs to be mounted? Update: When I run dmesg after plugging the device in, I see the following at the end: usb 1-1: new high speed USB device using ehci_marvell and address 6 usb 1-1: device not accepting address 6, error -71 usb 1-1: new high speed USB device using ehci_marvell and address 7 usb 1-1: device not accepting address 7, error -71 usb 1-1: new high speed USB device using ehci_marvell and address 8 usb 1-1: device not accepting address 8, error -71 usb 1-1: new high speed USB device using ehci_marvell and address 9 usb 1-1: device not accepting address 9, error -71 And when I view /var/log/messages, I can see this: Sep 23 21:26:03 debian kernel: usb 1-1: new high speed USB device using ehci_ma$ Sep 23 21:26:04 debian kernel: usb 1-1: new high speed USB device using ehci_ma$ Sep 23 21:26:05 debian kernel: usb 1-1: new high speed USB device using ehci_ma$ Sep 23 21:26:05 debian kernel: usb 1-1: new high speed USB device using ehci_ma$ Unfortunately, I don't know what these mean.

  • Best method to redirect internal DNS to external website?

    - by ProfessionalAmateur
    We host several web based applications outside of intranet. The URL's to these applications are long, complex and overall not user friendly. Ex: http://hostingsite:port/approot/folder/folder/login.aspx <-- (production) http://hostingsite:port22/approot/folder/folder/login.aspx <-- (dev) http://hostingsite:port33/approot/folder/folder/login.aspx <-- (test) I'd like to create an internal DNS entry to allow users to access these sites with ease. Ex: http://prod --> http://hostingsite:port/approot/folder/folder/login.aspx http://dev --> http://hostingsite:port22/approot/folder/folder/login.aspx I'm not familiar with the DNS process and setup, as far as I know a DNS can only be redirected to an IP, but not to subdomains for directory paths as described above? Is this a correct assumption? I am thinking for throwing up an internal webserver that will listen to the internal DNS entries and redirect to the external sites. http://prod --> [internal webserver] --> redirect --> http://hostingsite:port/approot/folder/folder/login.aspx Is there a better way to do this?

  • Using a nat rule to translate 80/443 traffic to web server, but internal users cannot access it using external ip/domain name

    - by Josh
    I am using Cisco ASDM for ASA I have my internal network called soa. My outside interface is called outside. Let's say my outside IP given to me by my ISP isp is y.y.y.y I have a web server inside my network with a static ip of x.x.x.110. I have configured 2 static nat rules (one for http the other for https). Source is x.x.x.110. Interface is outside, service (http or https). Maybe I am doing this wrong, but when I run the packet tracer, I choose outside interface and for the source IP I used 8.8.8.8 and the destination ip is my outside IP address, y.y.y.y When I run that, it shows the packet traversing successfully, using 9 steps. For my other test, I switch to the soa interface, input an ip on that network, and leave the destination the same. This test comes up with 2 steps and then fails on my access list. When I see the rule that fails, it is my catch all which is source: any desitnation: any, service: ip action: deny. What rule do I need to make to allow my soa network access to go out and come back in by my external IP addess (using a domain name attached to that ip in my dns, of course)?

  • Why does 3.5 mm audio out work through headphones but not through external speakers?

    - by Rickster
    I have a computer that has a 3.5 mm audio jack on the front of it. The computer itself has no speakers, so this is the only way to hear sound. If I plug headphones into it, the audio properly plays through the headphones, and if I plug in external speakers it used to play through them as well. Just today I turned on my computer and the audio no longer plays through the speakers, but if I plug in the headphones instead it works. The speakers aren't broken, as both the speakers and headphones work in my iPod and play music. I thought that 3.5 mm jacks could not send data back to the computer, and the computer had no way of differentiating between different devices plugged into the jack. If this is true, how is it that the computer plays audio through the headphones but not through speakers plugged into the same 3.5 mm jack, and both devices are functional? Or is my knowledge on 3.5 mm jacks incorrect? I don't believe drivers are important, as the same driver runs the 3.5 mm jack for all devices, but if necessary I can provide additional information. Any ideas would be appreciated. Thanks!

  • How to back up initial state of external backup drive?

    - by intuited
    I've picked up an HP Simplesave external drive. It comes with some fancy software that is of no use to me because I don't use Windows. Like many current consumer-targeted backup drives, the backup software is actually contained on the drive itself. I'd like to save the drive's initial state so that I can restore it if I decide to sell it. The backup box itself is somewhat customized: in addition to the hard drive device, it presents a CDROM-like device on /dev/sr0. I gather that the purpose of this cdrom device is to bootstrap via Windows autoplay the backup application which lives on the disk itself. I wouldn't suppose any guarantees about how it does this, so it seems important to preserve the exact state of the disk. The drive is formatted with a single 500GB NTFS partition. My initial thought was to use dd to dump the disk (/dev/sdb) itself, but this proved impractical, as the resulting file was not sparse. This seemed to be because the NTFS empty space is not filled with zeroes, but with a repeating series of 16 bytes. I tried gzipping the output of dd. This reduced to the file to a manageable size — the first 18GB was compressed to 81MB, versus 47MB to tarball the contents of the mounted filesystem — but it was very slow on my admittedly somewhat derelict Pentium M processor. The time to do that first 18GB was about 30 minutes. So I've resorted to dumping the disk state and partition data separately. I've dumped the partition state with sfdisk -d /dev/sdb > sfdisk.-d.out I've also created a compressed image of the NTFS partition (the only one on the disk) with ntfsclone --save-image --output - /dev/sdb1 | gzip -c > ntfsclone.img.gz Is there anything else I should do to ensure that I can restore the precise original state of the drive?

  • Laptop + External Monitor: Possible to Scale Mouse-crossover Position?

    - by Brian Lacy
    I have a laptop with a 16" screen @ 1366x768 resolution, and a 24" external monitor at 1920x1200 resolution. I'm extending the Windows 7 desktop onto the other screen. The 24" is the secondary monitor, and is positioned so the bottom of that screen lines up with the bottom of the 16" screen. Currently, if I move the mouse to the top portion of the 24" screen, then move left, the mouse will stop at the edge of the 24" screen until I move it down far enough to get into the range of the 16" screen. So that's all pretty standard; but I'm wondering if there's any software out there that will allow me to "scale" the mouse-crossover position, such that if I'm at the TOP of the 24" screen and move left, the mouse will cross to the TOP of the 16" screen, whereas if I'm at the BOTTOM of the 24" screen, crossing over will position the mouse at the BOTTOM of the 16" screen. So then, if the mouse cursor is on the 24" screen at (x,y) position (10,600), and I move 20 pixels left, the mouse is now on the 16" screen at position (1356,384). Anyone know of such a solution?? Note: I also use Ubuntu, so if there's a solution to this for X, but not Windows, I'd be interested in that also.

  • Is there a way to set up a Linux pipe to non-buffering or line-buffering?

    - by ern0
    My program is controlling an external application on Linux, passing in input commands via a pipe to the external applications stdin, and reading output result via a pipe from the external applications stdout. The problem is that writes to pipes are buffered by block, and not by line, and therefore delays occur before my app receives data output by the external application. The external application cannot be altered to add explicit fflush() calls. When I set the external application to /bin/cat -n (it echoes back the input, with line numbers added), it works correctly, it seems, cat flushes after each line. The only way to force the external application to flush, is sending exit command to it; as it receives the command, it flushes, and all the answers appears on the stdout, just before exiting. I'm pretty sure, that Unix pipes are appropiate solution for that kind of interprocess communication (pseudo server-client), but maybe I'm wrong. (I've just copied some text from a similar question: Force another program's standard output to be unbuffered using Python)

  • Where to put external archives to configure running in Eclipse?

    - by Buggieboy
    As a Java/Eclipse noob coming from a Visual Studio .NET background, I'm trying to understand how to set up my run/debug environment in the Eclipse IDE so I can start stepping through code. I have built my application with separate src and bin hierarchies for each library project, and each project has its own jar. For example, in a Windows environment, I have something like: c:\myapp\myapp_main\src\com\mycorp\myapp\main ...and a parallel "bin" tree like this: c:\myapp\myapp_main\bin\com\mycorp\myapp\main Other supporting projects are, similarly: **c:\myapp\myapp_util\src\com\mycorp\myapp\uti**l (and a parallel "bin" tree.) ... etc. So, I end up with, e.g., myapp_util.jar in the ...\myapp_util\bin... path and then add that as an external archive to my myapp_main project. I also use utilities like gluegen-rt.jar, which I add ad external dependencies to the projects requiring them. I have been able to run outside of the Eclipse environment, by copying all my project jars, gluegen-rt DLL, etc., into a "lib" subfolder of some directory and executing something like: java -Djava.library.path=lib -DfullScreen=false -cp lib/gluegen-rt.jar;lib/myapp_main.jar;lib/myapp_util.jar; com.mycorp.myapp.Main When I first pressed F11 to debug, however, I got a message about something like /com/sun/../glugen... not being found by the class loader. So, to debug, or even just run, in Ecplipse, I tried setting up my VM arguments in the Galileo Debug - (Run/Debug) Configurations to be the command line above, beginning at "-Djava.libary.path...". I've put a lib subdirectory - just like the above with all jars and the native gluegen DLL - in various places, such as beneath the folder that my main jar is built in and as a subfolder of my Ecplipse starting workspace folder, but now Eclipse can't find the main class: java.lang.NoClassDefFoundError: com.mycorp.myapp.Main Although the Classpath says that it is using the "default classpath", whatever that is. Bottom line, how do I assemble the constituent files of a multi-project application so that I can run or debug in Ecplipse?
