  • CSS rules not getting applied in JSPs ?

    - by lakshmanan
    Im building a web application using struts2. I have an authentication interceptor at the top of all the interceptors (I have set it up as such) which checks whether a user is logged in. If not, it will give a login page as result. In login page, I have some set of standard CSS rules which I use for all the JSPs in the app. But that login page coming via that interceptor is not getting applied with CSS rules. Don't know why. Here is my JSP login page. <%@ page language="java" contentType="text/html; charset=ISO-8859-1" pageEncoding="ISO-8859-1"%> <%@ taglib prefix="s" uri="/struts-tags" %> <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <link rel="stylesheet" href="styles/styles.css" type="text/css" /> <meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1"> <title>Projit Login </title> </head> <body> <div id="header"> <h1>Projit</h1> </div> <div id="col1"> <s:form action="/login.action"> <s:textfield name="some field" label="Enter somefield" /> <s:textfield name="username" label="Username" /> <s:password name="password" label="Password" /> <s:submit value="Sign In" /> </s:form> </div> <div id="col2"> <h3>Login</h3> </div> <div id="footer"> some footer </div> </body> </html> the css file is present in WebContent/styles/styles.css I am using eclipse for development. this problem of CSS rules not getting applied occurs at times for other jsps as well inspite of the CSS file being present in the correct location. I guess there must be some URL thing behind this problem. I have tried hard but it is not working till now. Please help.

  • Why are my USB 2.0 devices hanging Windows XP?

    - by BenAlabaster
    Background on the machine I'm having a problem with: The machine was inherited and appears to be circa 2003 (there's a date stamp on the power supply which leads me to this conclusion). I've got it set up as a Skype terminal for my 2 year old to keep in touch with her grandparents and other members of the family - which everyone loves. It has a DFI CM33-TL/G ATX (identified using SiSoft Sandra) motherboard hosting an Intel Celeron 1.3GHz CPU, 768Mb PC133 SDRAM, a D-LINK WDA-2320 54G Wi-Fi network card and a generic USB 2.0 expansion board based on the NEC uPD720102 chipset containing 3 external and 1 internal USB sockets. It's also hosting a 1.44Mb floppy drive on FDD0, a new 80Gb Western Digital hard drive running as master on IDE0 and a Panasonic DVD+/-RW running as master on IDE1. All this is sitting in a slimline case running off a Macron Power MPT-135 135W Flex power supply. The motherboard is running a version of Award BIOS 05/24/2002-601T-686B-6A6LID4AC-00. Could this be updated? If so, from where? I've raked through the manufacturer's website but can't find any hint of downloads for either drivers or BIOS updates. The hard disk is freshly formatted and built with Windows XP Professional/Service Pack 3 and is up to date with all current patches. In addition to Windows XP, the only other software it's running is Skype 4.1 (4.2 hangs the whole machine as soon as it starts up, requiring a hard boot to recover). It's got a Daytek MV150 15" touch screen hooked up to the on board VGA and COM1 sockets with the most current drivers from the Daytek website and the most current version of ELO-Touchsystems drivers for the touch component. The webcam is a Logitech Webcam C200 with the latest drivers from the Logitech website. The problem: If I hook any devices to the USB 2.0 sockets, it hangs the whole machine and I have to hard boot it to get it back up. If I have any devices attached to the USB 2.0 sockets when I boot up, it hangs before Windows gets to the login prompt and I have to hard boot it to recover. Workarounds found: I can plug the same devices into the on board USB 1.0 sockets and everything works fine, albeit at reduced performance. I've tried 3 different kinds of USB thumb drives, 3 different makes/models of webcams and my iPhone all with the same effect. They're recognized and don't hang the machine when I hook them to the USB 1.0 but if I hook them to the USB 2.0 ports, the machine hangs within a couple of seconds of recognizing the devices were connected. Attempted solutions: I've seen suggestions that this could be a power problem - that the PSU just doesn't have the wattage to drive these ports. While I'm doubtful this is the problem [after all the motherboard has the same standard connector regardless of the PSU wattage], I tried disabling all the on board devices that I'm not using - on board LAN, the second COM port, the AGP connector etc. through the BIOS in what I'm sure is a futile attempt to reduce the power consumption... I also modified the ACPI and power management settings. It didn't have any noticeable affect, although it didn't do any harm either. Could the wattage of the PSU really cause this problem? If it can, is there anything I need to be aware of when replacing it or do I just need to make sure it's got a higher wattage than the current one? My interpretation was that the wattage only affected the number of drives you could hook up to the power connectors, is that right? I've installed the USB card in another machine and it works without issue, so it's not a problem with the USB card itself, and Windows says the card is installed and working correctly... right up until I connect a device to it. The only thing I haven't done which I only just thought of while writing this essay is trying the USB 2.0 card in a different PCI slot, or re-ordering the wi-fi and USB cards in the slots... although I'm not sure if this will make any difference - does anyone have any experience that would suggest this might work? Other thoughts/questions: Perhaps this is an incompatibility between the USB 2.0 card and the BIOS, would re-flashing the BIOS with a newer version help? Do I need to be able to identify the manufacturer of the motherboard in order to be able to find a BIOS edition specific for this motherboard or will any version of Award BIOS function in its place? Question: Does anyone have any ideas that could help me get my USB 2.0 devices hooked up to this machine?

  • BASH, multiple arrays and a loop.

    - by S1syphus
    At work, we 7 or 8 hardrives we dispatch over the country, each have unique labels which are not sequential. Ideally drives are plugged in our desktop, then gets folders from the server that correspond to the drive name. Sometimes, only one hard drive gets plugged in sometimes multiples, possibly in the future more will be added. Each is mounts to /Volumes/ and it's identifier; so for example /Volumes/f00, where f00 is the identifier. What I want to happen, scan volumes see if any any of the drives are plugged in, then checks the server to see if the folder exists, if ir does copy folder and recursive folders. Here is what I have so far, it checks if the drive exists in Volumes: #!/bin/sh #Declare drives in the array ARRAY=( foo bar long ) #Get the drives from the array DRIVES=${#ARRAY[@]} #Define base dir to check BaseDir="/Volumes" #Define shared server fold on local mount points #I plan to use AFP eventually, but for the sake of ease #using a local mount. ServerMount="BigBlue" #Define folder name for where files are to come from Dispatch="File-Dispatch" dir="$BaseDir/${ARRAY[${i}]}" #Loop through each item in the array and check if exists on /Volumes for (( i=0;i<$DRIVES;i++)); do dir="$BaseDir/${ARRAY[${i}]}" if [ -d "$dir" ]; then echo "$dir exists, you win." else echo "$dir is not attached." fi done What I can't figure out how to do, is how to check the volumes for the server while looping through the harddrive mount points. So I could do something like: #!/bin/sh #Declare drives, and folder location in arrays ARRAY=( foo bar long ) ARRAY1=($(ls ""$BaseDir"/"$ServerMount"/"$Dispatch"")) #Get the drives from the array DRIVES=${#ARRAY[@]} SERVERFOLDER=${#ARRAY1[@]} #Define base dir to check BaseDir="/Volumes" #Define shared server fold on local mount points ServerMount="BigBlue #Define folder name for where files are to come from Dispatch="File-Dispatch" dir="$BaseDir/${ARRAY[${i}]}" #List the contents from server directory into array ARRAY1=($(ls ""$BaseDir"/"$ServerMount"/"$Dispatch"")) echo ${list[@]} for (( i=0;i<$DRIVES;i++)); (( i=0;i<$SERVERFOLDER;i++)); do dir="$BaseDir/${ARRAY[${i}]}" ser="${ARRAY1[${i}]}" if [ "$dir" =~ "$sir" ]; then cp "$sir" "$dir" else echo "$dir is not attached." fi done I know, that is pretty wrong... well very, but I hope it gives you the idea of what I am trying to achieve. Any ideas or suggestions?

  • Why does using ASP.NET OutputCache keep returning a 200 OK, not a 304 Not Modified?

  • Android - MapView contained within a Listview

    - by Ryan
    Hello, Currently I am trying to place a MapView within a ListView. Has anyone had any success with this? Is it even possible? Here is my code: ListView myList = (ListView) findViewById(android.R.id.list); List<Map<String, Object>> groupData = new ArrayList<Map<String, Object>>(); Map<String, Object> curGroupMap = new HashMap<String, Object>(); groupData.add(curGroupMap); curGroupMap.put("ICON", R.drawable.back_icon); curGroupMap.put("NAME","Go Back"); curGroupMap.put("VALUE","By clicking here"); Iterator it = data.entrySet().iterator(); while (it.hasNext()) { //Get the key name and value for it Map.Entry pair = (Map.Entry)it.next(); String keyName = (String) pair.getKey(); String value = pair.getValue().toString(); if (value != null) { //Add the parents -- aka main categories curGroupMap = new HashMap<String, Object>(); groupData.add(curGroupMap); //Push the correct Icon if (keyName.equalsIgnoreCase("Phone")) curGroupMap.put("ICON", R.drawable.phone_icon); else if (keyName.equalsIgnoreCase("Housing")) curGroupMap.put("ICON", R.drawable.house_icon); else if (keyName.equalsIgnoreCase("Website")) curGroupMap.put("ICON", R.drawable.web_icon); else if (keyName.equalsIgnoreCase("Area Snapshot")) curGroupMap.put("ICON", R.drawable.camera_icon); else if (keyName.equalsIgnoreCase("Overview")) curGroupMap.put("ICON", R.drawable.overview_icon); else if (keyName.equalsIgnoreCase("Location")) curGroupMap.put("ICON", R.drawable.map_icon); else curGroupMap.put("ICON", R.drawable.icon); //Pop on the Name and Value curGroupMap.put("NAME", keyName); curGroupMap.put("VALUE", value); } } curGroupMap = new HashMap<String, Object>(); groupData.add(curGroupMap); curGroupMap.put("ICON", R.drawable.back_icon); curGroupMap.put("NAME","Go Back"); curGroupMap.put("VALUE","By clicking here"); //Set up adapter mAdapter = new SimpleAdapter( mContext, groupData, R.layout.exp_list_parent, new String[] { "ICON", "NAME", "VALUE" }, new int[] { R.id.photoAlbumImg, R.id.rowText1, R.id.rowText2 } ); myList.setAdapter(mAdapter); //Bind the adapter to the list Thanks in advance for your help!!

  • Bassistance Autocomplete Plugin - Search Page Replacement

    - by Dante
    Hi, i've setup an autocomplete field that searches my database which works fine: $("#autocomplete input#lookupAccount").autocomplete("lib/php/autocomplete_backend.php", { width: 300, selectFirst: false, delay: 250 }); When a user clicks on a result I want to refer them to another page depending on what they've been clicking. In the documentation I find the following: Search Page Replacement An autocomplete plugin can be used to search for a term and redirect to a page associated with a resulting item. The following is one way to achieve the redirect: var data = [ {text:'Link A', url:'/page1'}, {text:'Link B', url: '/page2'} ]; $("...").autocomplete(data, { formatItem: function(item) { return item.text; } }).result(function(event, item) { location.href = item.url; }); So i need to return the following from my PHP file : {text:'link A', url:'/page1'},... But my PHP file now returns $returnData = "<ul>"; if(isset($results)){ for($j=0; $j < count($results); $j++){ if($results[$j][0] == "account"){ if($j % 2){ $returnData .= "<li>".$results[$j][1]."<br /><i>".$results[$j][2].", ".$results[$j][3]." ".$results[$j][4]."</i></li>"; } else { $returnData .= "<li style=\"background: blue\">".$results[$j][1]."<br /><i>".$results[$j][2].", ".$results[$j][3]." ".$results[$j][4]."</i></li>"; } } else { $returnData .= "<li style=\"background: yellow\"><i>".$results[$j][1]."</i> (".$results[$j][2].")</li>"; } } $returnData .= "</ul>"; echo $returnData; } else { echo "Sorry geen resultaten!"; } So it loops through an array and returns an li value depending on what it finds in the array. How can I match that with: {text:'link A', url:'/page1'}???

  • How to do an fetch request with expressions like this on the iPhone?

    - by dontWatchMyProfile
    The documentation has an example on how to retrieve simple values only, rather than managed objects. This remembers a lot SQL using aliases and functions to only retrieve calculated values. So, actually pretty geeky stuff. To get the minimum date from a bunch of records, this is used on the mac: NSFetchRequest *request = [[NSFetchRequest alloc] init]; NSEntityDescription *entity = [NSEntityDescription entityForName:@"Event" inManagedObjectContext:context]; [request setEntity:entity]; // Specify that the request should return dictionaries. [request setResultType:NSDictionaryResultType]; // Create an expression for the key path. NSExpression *keyPathExpression = [NSExpression expressionForKeyPath:@"creationDate"]; // Create an expression to represent the minimum value at the key path 'creationDate' NSExpression *minExpression = [NSExpression expressionForFunction:@"min:" arguments:[NSArray arrayWithObject:keyPathExpression]]; // Create an expression description using the minExpression and returning a date. NSExpressionDescription *expressionDescription = [[NSExpressionDescription alloc] init]; // The name is the key that will be used in the dictionary for the return value. [expressionDescription setName:@"minDate"]; [expressionDescription setExpression:minExpression]; [expressionDescription setExpressionResultType:NSDateAttributeType]; // Set the request's properties to fetch just the property represented by the expressions. [request setPropertiesToFetch:[NSArray arrayWithObject:expressionDescription]]; // Execute the fetch. NSError *error; NSArray *objects = [managedObjectContext executeFetchRequest:request error:&error]; if (objects == nil) { // Handle the error. } else { if ([objects count] > 0) { NSLog(@"Minimum date: %@", [[objects objectAtIndex:0] valueForKey:@"minDate"]; } } [expressionDescription release]; [request release]; Nice, I though - but having a deep look into NSExpression -expressionForFunction:arguments: it turns out that iPhone OS does NOT support the min: function. Well, probably there's a nifty way to use an own function for this kind of stuff on the iPhone as well? Because on thing I'm already worrying about is, how I'm gonna sort a table based on the calculated distance of targets on a map (location-based stuff).

  • Issue with SPI (Serial Port Comm), stuck on ioctl()

    - by stef
    I'm trying to access a SPI sensor using the SPIDEV driver but my code gets stuck on IOCTL. I'm running embedded Linux on the SAM9X5EK (mounting AT91SAM9G25). The device is connected to SPI0. I enabled CONFIG_SPI_SPIDEV and CONFIG_SPI_ATMEL in menuconfig and added the proper code to the BSP file: static struct spi_board_info spidev_board_info[] { { .modalias = "spidev", .max_speed_hz = 1000000, .bus_num = 0, .chips_select = 0, .mode = SPI_MODE_3, }, ... }; spi_register_board_info(spidev_board_info, ARRAY_SIZE(spidev_board_info)); 1MHz is the maximum accepted by the sensor, I tried 500kHz but I get an error during Linux boot (too slow apparently). .bus_num and .chips_select should correct (I also tried all other combinations). SPI_MODE_3 I checked the datasheet for it. I get no error while booting and devices appear correctly as /dev/spidevX.X. I manage to open the file and obtain a valid file descriptor. I'm now trying to access the device with the following code (inspired by examples I found online). #define MY_SPIDEV_DELAY_USECS 100 // #define MY_SPIDEV_SPEED_HZ 1000000 #define MY_SPIDEV_BITS_PER_WORD 8 int spidevReadRegister(int fd, unsigned int num_out_bytes, unsigned char *out_buffer, unsigned int num_in_bytes, unsigned char *in_buffer) { struct spi_ioc_transfer mesg[2] = { {0}, }; uint8_t num_tr = 0; int ret; // Write data mesg[0].tx_buf = (unsigned long)out_buffer; mesg[0].rx_buf = (unsigned long)NULL; mesg[0].len = num_out_bytes; // mesg[0].delay_usecs = MY_SPIDEV_DELAY_USECS, // mesg[0].speed_hz = MY_SPIDEV_SPEED_HZ; mesg[0].bits_per_word = MY_SPIDEV_BITS_PER_WORD; mesg[0].cs_change = 0; num_tr++; // Read data mesg[1].tx_buf = (unsigned long)NULL; mesg[1].rx_buf = (unsigned long)in_buffer; mesg[1].len = num_in_bytes; // mesg[1].delay_usecs = MY_SPIDEV_DELAY_USECS, // mesg[1].speed_hz = MY_SPIDEV_SPEED_HZ; mesg[1].bits_per_word = MY_SPIDEV_BITS_PER_WORD; mesg[1].cs_change = 1; num_tr++; // Do the actual transmission if(num_tr > 0) { ret = ioctl(fd, SPI_IOC_MESSAGE(num_tr), mesg); if(ret == -1) { printf("Error: %d\n", errno); return -1; } } return 0; } Then I'm using this function: #define OPTICAL_SENSOR_ADDR "/dev/spidev0.0" ... int fd; fd = open(OPTICAL_SENSOR_ADDR, O_RDWR); if (fd<=0) { printf("Device not found\n"); exit(1); } uint8_t buffer1[1] = {0x3a}; uint8_t buffer2[1] = {0}; spidevReadRegister(fd, 1, buffer1, 1, buffer2); When I run it, the code get stuck on IOCTL! I did this way because, in order to read a register on the sensor, I need to send a byte with its address in it and then get the answer back without changing CS (however, when I tried using write() and read() functions, while learning, I got the same result, stuck on them). I'm aware that specifying .speed_hz causes a ENOPROTOOPT error on Atmel (I checked spidev.c) so I commented that part. Why does it get stuck? I though it can be as the device is created but it actually doesn't "feel" any hardware. As I wasn't sure if hardware SPI0 corresponded to bus_num 0 or 1, I tried both, but still no success (btw, which one is it?). UPDATE: I managed to have the SPI working! Half of it.. MOSI is transmitting the right data, but CLK doesn't start... any idea?

  • unformatted input to a std::string instead of c-string from binary file.

    - by posop
    ok i have this program working using c-strings. I am wondering if it is possible to read in blocks of unformatted text to a std::string? I toyed arround with if >> but this reads in line by line. I've been breaking my code and banging my head against the wall trying to use std::string, so I thought it was time to enlist the experts. Here's a working program you need to supply a file "a.txt" with some content to make it run. i tried to fool around with: in.read (const_cast<char *>(memblock.c_str()), read_size); but it was acting odd. I had to do std::cout << memblock.c_str() to get it to print. and memblock.clear() did not clear out the string. anyway, if you can think of a way to use STL I would greatly appreciate it. Here's my program using c-strings // What this program does now: copies a file to a new location byte by byte // What this program is going to do: get small blocks of a file and encrypt them #include <fstream> #include <iostream> #include <string> int main (int argc, char * argv[]) { int read_size = 16; int infile_size; std::ifstream in; std::ofstream out; char * memblock; int completed = 0; memblock = new char [read_size]; in.open ("a.txt", std::ios::in | std::ios::binary | std::ios::ate); if (in.is_open()) infile_size = in.tellg(); out.open("b.txt", std::ios::out | std::ios::trunc | std::ios::binary); in.seekg (0, std::ios::beg);// get to beginning of file while(!in.eof()) { completed = completed + read_size; if(completed < infile_size) { in.read (memblock, read_size); out.write (memblock, read_size); } // end if else // last run { delete[] memblock; memblock = new char [infile_size % read_size]; in.read (memblock, infile_size % read_size + 1); out.write (memblock, infile_size % read_size ); } // end else } // end while } // main if you see anything that would make this code better please feel free to let me know.

  • Feedback on iterating over type-safe enums

    In response to the earlier SO question "Enumerate over an enum in C++", I came up with the following reusable solution that uses type-safe enum idiom. I'm just curious to see the community feedback on my solution. This solution makes use of a static array, which is populated using type-safe enum objects before first use. Iteration over enums is then simply reduced to iteration over the array. I'm aware of the fact that this solution won't work if the enumerators are not strictly increasing. template<typename def, typename inner = typename def::type> class safe_enum : public def { typedef typename def::type type; inner val; static safe_enum array[def::end - def::begin]; static bool init; static void initialize() { if(!init) // use double checked locking in case of multi-threading. { unsigned int size = def::end - def::begin; for(unsigned int i = 0, j = def::begin; i < size; ++i, ++j) array[i] = static_cast<typename def::type>(j); init = true; } } public: safe_enum(type v = def::begin) : val(v) {} inner underlying() const { return val; } static safe_enum * begin() { initialize(); return array; } static safe_enum * end() { initialize(); return array + (def::end - def::begin); } bool operator == (const safe_enum & s) const { return this->val == s.val; } bool operator != (const safe_enum & s) const { return this->val != s.val; } bool operator < (const safe_enum & s) const { return this->val < s.val; } bool operator <= (const safe_enum & s) const { return this->val <= s.val; } bool operator > (const safe_enum & s) const { return this->val > s.val; } bool operator >= (const safe_enum & s) const { return this->val >= s.val; } }; template <typename def, typename inner> safe_enum<def, inner> safe_enum<def, inner>::array[def::end - def::begin]; template <typename def, typename inner> bool safe_enum<def, inner>::init = false; struct color_def { enum type { begin, red = begin, green, blue, end }; }; typedef safe_enum<color_def> color; template <class Enum> void f(Enum e) { std::cout << static_cast<unsigned>(e.underlying()) << std::endl; } int main() { std::for_each(color::begin(), color::end(), &f<color>); color c = color::red; }

  • Uncenter MkMapView

    - by Makinitez21
    I am trying to "uncenter" the map view and remove all annotations. the reason for this is that the mapView will be used by different view controllers to display different annotations and locations. What's happening now is that i am using the "remove annotations" method and i removes them, but the map stays centered on the spot and thus when the new annotations come in, it does not move. Is there a way to reset the region and if so, what value do i reset it to. I tried nil, zero and some calculated value but "core animation" says they are all invalid. how do i get that to zoom out and back in on my new annotations? here is some code -(void)recenterMap { NSArray *coordinates = [_mapView valueForKeyPath:@"annotations.coordinate"]; CLLocationCoordinate2D maxCoord = {-90.0f, -180.0f}; CLLocationCoordinate2D minCoord = {90.0f, 180.0f}; //NSLog(@"%@", [coordinates description]); for (NSValue *value in coordinates) { CLLocationCoordinate2D coord = {0.0f, 0.0f}; [value getValue: &coord]; if(coord.longitude > maxCoord.longitude) { maxCoord.longitude = coord.longitude; } if(coord.latitude > maxCoord.latitude){ maxCoord.latitude = coord.latitude; } if(coord.longitude < minCoord.longitude){ minCoord.longitude = coord.longitude; } if(coord.latitude < minCoord.latitude){ minCoord.latitude = coord.latitude; } } MKCoordinateRegion region = {{0.0f, 0.0f}, {0.0f, 0.0f}}; region.center.longitude = (minCoord.longitude + maxCoord.longitude) / 2.0; region.center.latitude = (minCoord.latitude + maxCoord.latitude) / 2.0; region.span.longitudeDelta = maxCoord.longitude - minCoord.longitude; region.span.latitudeDelta = maxCoord.latitude - minCoord.latitude; [_mapView setRegion: region animated: YES]; } Thats the recenter methos i'm using - (MKAnnotationView *)mapView: (MKMapView *)mapView viewForAnnotation: (id <MKAnnotation>)annotation{ MKAnnotationView *view = nil; if(annotation != mapView.userLocation){ Annotation *schoolAnn = (Annotation*)annotation; view = [self.mapView dequeueReusableAnnotationViewWithIdentifier:@"schoolLoc"]; if(nil == view){ view = [[[MKPinAnnotationView alloc] initWithAnnotation:schoolAnn reuseIdentifier:@"schoolLoc"]autorelease]; } [(MKPinAnnotationView *)view setAnimatesDrop:YES]; [view setCanShowCallout:YES]; } else { [self recenterMap]; } return view; } This "else" piece waits until the blue marble drops in then recenters the map. The problem i have with that part is that when i go back to the previous View Controller i remove all annotations, so when i come back in the User location (for some reason) does not pop back in. How do i get this to pop back in? thanks in advance guys

  • Read email from incoming mail server(POP)

    - by nccsbim071
    Hi, I have used an open source code from codeproject to read email from incoming mail server(POP Server). The code can be found at following location: http://www.codeproject.com/KB/IP/Pop3MimeClient.aspx So far it works fine i can read emails. My objective of using this code was to retrieve emails from POP server and process them. My problem is: If i use gmails pop server "pop.gmail.com" and run the appplication. I get only those emails that i have not retrieved since the last time i run the application. but if i use my clients pop server everytime i run the application i get all the emails in the pop server. for example: If i use gmail pop server: pop.gmail.com I have three emails in the pop server. I haven't run the application. I am running the application for the first time. Application reads the email, this time i will get 3 all the three email. I run the application second time, my application will not read any emails this time because i have already read the 3 existing one. This is fine, this is what i want. Now i send email to pop.gmail.com. I run the application again for the third time, this time i will only get the email that has just arrived that is the fourth one. This is good behaviour, this is what i want. But if i use my clients pop server: No matter how many times i run the application, it reads all the emails in the mail box. This will create problem for me, because i am thinking of building a window service that will read emails from pop server and process them. This service will run continuously. I will process emails in the pop serve then sleep for let's say 1 minute and the process the emails again. If the application downloaded from codeproject reads all the emails all the time, my clients mailbox can have like thousands for email in this mail box, so this would not be feasible for me. Is there some settings that is to be made at my client's pop server that will allow my application to retrieve only those emails that i have not read since last time i run the service or any help Please help, thanks,

  • Sharepoint web part stops working because of Resources.en-US.resx file

    - by Eric C
    I've been developing a Sharepoint web part, which had been working fine upon deployment. The web part has been developed with WSP Builder, packaged up and then deployed via stsadm. The web part has been deployed tens, if not a hundred times to the dev box with no problems. Now, the web part throws an error which breaks the page it's on: Object reference not set to an instance of an object. Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. Exception Details: System.NullReferenceException: Object reference not set to an instance of an object.

I've retracted the web part manually through Solution Management, retracted through stsadm, checked for the existence of the resource file, which is nowhere to be found. I'm pretty much at a loss to why this happened or how to resolve it.

  • Starting ActiveMQ message listener in Tomcat?

    - by Nick Swarr
    I've created an ActiveMQ MessageListener and configured it using Spring. I'm hosting the listener in Tomcat. When I start up the web application (that features only the listener), should the listener automatically start? Or do I need additional configuration? Here's what I have. First, updated the web.xml to allow spring to configure itself on startup, <?xml version="1.0" encoding="UTF-8"?> <web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <context-param> <param-name>contextConfigLocation</param-name> <param-value>/WEB-INF/classes/spring/applicationContext.xml</param-value> </context-param> </web-app> Then I created the applicationContext.xml to configure the ActiveMQ listener, <?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" xmlns:amq="http://activemq.apache.org/schema/core" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd"> <context:annotation-config /> <context:component-scan base-package="com.somepackage"/> <context:property-placeholder location="classpath:env.properties"/> <bean id="jmsFactory" class="org.apache.activemq.ActiveMQConnectionFactory"> <property name="brokerURL" value="tcp://localhost:61616" /> </bean> <bean id="documentListener" class="com.somepackage.SomeListener" /> <bean id="container" class="org.springframework.jms.listener.DefaultMessageListenerContainer"> <property name="connectionFactory" ref="cachingConnectionFactory"/> <property name="messageListener" ref="documentListener"/> <property name="destinationName" value="STOCKS.MSFT" /> </bean> <bean id="cachingConnectionFactory" class="org.springframework.jms.connection.CachingConnectionFactory"> <property name="targetConnectionFactory" ref="jmsFactory" /> <property name="sessionCacheSize" value="1" /> </bean> </beans> And that's it. Based on what I've seen around the web, I can't tell if that's all I need? Maybe I need some other configuration in Tomcat to kick off the listener?

  • Dynamically adding values to a form with JQuery/Javascript

    - by bigstylee
    I am creating a private message system to allow users to communicate between one another within the context of the website (ie, not emails). I have created this function to handle all my form submissions. I would like to achieve a solution without modifying this function (ideally). $("form.reload").submit(function(){ alert($(this).serialize()); /* Debugging */ $.post($(this).attr("action"), $(this).serialize() ,function(data){ if(data){ $("#error").html(data); }else{ location.reload(); }; }); return false; }); Within my form I am using JQuery Autocomplete to find usernames. This function works perfectly. My first solution was to add buttons within the form with the necessary values. select: function(event, ui) { $("#message_to").append("<input type=\"button\" class=\"recipient\" name=\"recipients[]\" value=\"" + ui.item.label + "\" onclick=\"$(this).remove()\" />"); } <form method="post" action="/messages-create"> <div id="message_to"></div> </div> For some reason the values of recipients are not getting posted. My second solution was to add to a post array that already existed in the form select: function(event, ui) { $(input[name=recipeients[]).val = ui.item.label; /* Need to add to array, not replace! */ $("#message_to").append("<input type=\"button\" class=\"recipient\" name=\"recipient\" value=\"" + ui.item.label + "\" onclick=\"$(this).remove(); /* Remove from recipients */\" />"); } <form method="post" action="/messages-create" class="reload"> <input type="hidden" name="recipients[]" value="" /> <div id="message_to"></div> </div> This works ok, but I have been unable to work out how to append to the recipients[] array only replace with the new label. Moving on from this, I also need to know how to then remove this value from the array. Thanks in advance!

  • ASP.NET application developed in 32 bit environment not working in 64 bit environment

    - by jgonchik
    We have developed an ASP.NET website on a Windows 7 - 32 bit platform using Visual Studio 2008. This website is being hosted at a hosting company where we share a server with hundreds of other ASP.NET websites. We are in the process of changing our hosting to a dedicated Windows 2008 - 64 bit server. We have installed Visual Studio on this new server in order to debug our application. If we try to start the application on this new server using Visual Studios 2008's own web server (not IIS 7) we get the error below. We have tried to compile the application in both 32 as well as 64 bit mode. We also tried to compile to "Any CPU". But nothing helps. We also tried running Visual Studio as an administrator but without success. We get the following error: Server Error in '/' Application. The specified module could not be found.

  • Any way to speed up this hierarchical query?

    - by RenderIn
    I've got a serious performance problem with a hierarchical query that I can't seem to fix. I am modeling several organization charts in my database, each representing a virtual organization within our company. For example, we have several temporary committees that are created from time to time and there may be a Committee Organizer role at the top of this virtual hierarchy, with several people assigned to the Committee Member role beneath the organizer. Some of our virtual organizations have many levels and several branches at each level. I have a single table in which I represent all the role assignments. i.e. a ROLE_ID column and a PARENT_ROLE_ID column which is a foreign key to the ROLE_ID column. For each assignment we also store as a column the location in the company where this person has the assignment. For example, the Committee Organizer would have a company-level/ CEO assignment, while the committee members would have department-level assignments such as ACCOUNTING, MARKETING, etc. So to model the organizer/member relationship for two individuals we would have: ROLE_ID = 4 PARENT_ROLE_ID = NULL EMPLOYEE_NUMBER = 213423 COMPANY_LOCATION = CEO ROLE_ID = 5 PARENT_ROLE_ID = 4 EMPLOYEE_NUMBER = 838221 COMPANY_LOCATION = ACCOUNTING Here's where things get tricky. I have an application that every person in the organization can log in to. When they log in they should be able to view all the virtual organizations in our company. e.g. the committee members should be able to see the committee organizer and vice-versa. However, only the committee organizer should be able to edit the committee members. The difficulty is in determining whether an individual (who can have multiple role assignments) has edit access for each other assignment. While this seems simple in the example, consider a virtual organization in which we have President at the top, 5 departments directly beneath him, 2 subdepartments below each department. We only want people in the Accounting department to be able to edit individuals in the subdepartments belonging to the Accounting department. They should not have edit access to anybody in the Marketing department or its subdepartments. To determine edit access when a user views a virtual organization in our company I run a query that executes two inline views: A) Hierarchically query for all assignments in this virtual organization and using SYS_CONNECT_BY_PATH to store the entire path to each user/role/company_location and B) Hierarchically retrieve all the assignments the individual logged in has and using the SYS_CONNECT_BY_PATH to store the entire path to each of these assignments. The result of the query is all the records from A) plus a boolean determined by joining with B) which flags whether the logged in user has edit access for each record. Indexes don't seem to be helping... it simply appears that there is too much processing going on to separate all the records and then determine edit access. One issue is that I can't store the SYS_CONNECT_BY_PATH and index it... determining whether an individual record has edit access consists of comparing if: test_record_sys_path LIKE individual_record_sys_path || '%' Is a materialized view the answer?

  • Understanding CLR 2.0 Memory Model

    - by Eloff
    Joe Duffy, gives 6 rules that describe the CLR 2.0+ memory model (it's actual implementation, not any ECMA standard) I'm writing down my attempt at figuring this out, mostly as a way of rubber ducking, but if I make a mistake in my logic, at least someone here will be able to catch it before it causes me grief. Rule 1: Data dependence among loads and stores is never violated. Rule 2: All stores have release semantics, i.e. no load or store may move after one. Rule 3: All volatile loads are acquire, i.e. no load or store may move before one. Rule 4: No loads and stores may ever cross a full-barrier (e.g. Thread.MemoryBarrier, lock acquire, Interlocked.Exchange, Interlocked.CompareExchange, etc.). Rule 5: Loads and stores to the heap may never be introduced. Rule 6: Loads and stores may only be deleted when coalescing adjacent loads and stores from/to the same location. I'm attempting to understand these rules. x = y y = 0 // Cannot move before the previous line according to Rule 1. x = y z = 0 // equates to this sequence of loads and stores before possible re-ordering load y store x load 0 store z Looking at this, it appears that the load 0 can be moved up to before load y, but the stores may not be re-ordered at all. Therefore, if a thread sees z == 0, then it also will see x == y. If y was volatile, then load 0 could not move before load y, otherwise it may. Volatile stores don't seem to have any special properties, no stores can be re-ordered with respect to each other (which is a very strong guarantee!) Full barriers are like a line in the sand which loads and stores can not be moved over. No idea what rule 5 means. I guess rule 6 means if you do: x = y x = z Then it is possible for the CLR to delete both the load to y and the first store to x. x = y z = y // equates to this sequence of loads and stores before possible re-ordering load y store x load y store z // could be re-ordered like this load y load y store x store z // rule 6 applied means this is possible? load y store x // but don't pop y from stack (or first duplicate item on top of stack) store z What if y was volatile? I don't see anything in the rules that prohibits the above optimization from being carried out. This does not violate double-checked locking, because the lock() between the two identical conditions prevents the loads from being moved into adjacent positions, and according to rule 6, that's the only time they can be eliminated. So I think I understand all but rule 5, here. Anyone want to enlighten me (or correct me or add something to any of the above?)
