  • Ruby SerialPorts

    - by Seth Archer
    I'm using the ruby serial port gem. After I open up the port I send the data I want like this. sp.write [200.chr, 30.chr, 7.chr, 5.chr, 1.chr, 2.chr, 0.chr, 245.chr].to_s It doesn't work, but if I put it in a loop of around 200 times: 200.times do sp.write [200.chr, 30.chr, 7.chr, 5.chr, 1.chr, 2.chr, 0.chr, 245.chr].to_s end It works. Any ideas on why this is happening?

  • UTF-8 to Unicode conversion

    - by sandeep
    Hi, I am having problems with converting UTF-8 to Unicode. Below is the code: int charset_convert( char * string, char * to_string,char* charset_from, char* charset_to) { char *from_buf, *to_buf, *pointer; size_t inbytesleft, outbytesleft, ret; size_t TotalLen; iconv_t cd; if (!charset_from || !charset_to || !string) /* sanity check */ return -1; if (strlen(string) < 1) return 0; /* we are done, nothing to convert */ cd = iconv_open(charset_to, charset_from); /* Did I succeed in getting a conversion descriptor ? */ if (cd == (iconv_t)(-1)) { /* I guess not */ printf("Failed to convert string from %s to %s ", charset_from, charset_to); return -1; } from_buf = string; inbytesleft = strlen(string); /* allocate max sized buffer, assuming target encoding may be 4 byte unicode */ outbytesleft = inbytesleft *4 ; pointer = to_buf = (char *)malloc(outbytesleft); memset(to_buf,0,outbytesleft); memset(pointer,0,outbytesleft); ret = iconv(cd, &from_buf, &inbytesleft, &pointer, &outbytesleft);ing memcpy(to_string,to_buf,(pointer-to_buf); } main(): int main() { char UTF []= {'A', 'B'}; char Unicode[1024]= {0}; char* ptr; int x=0; iconv_t cd; charset_convert(UTF,Unicode,"UTF-8","UNICODE"); ptr = Unicode; while(*ptr != '\0') { printf("Unicode %x \n",*ptr); ptr++; } return 0; } It should give A and B but i am getting: ffffffff fffffffe 41 Thanks, Sandeep

  • Error while opening port in Java

    - by Deepak
    I am getting the following error while trying to open the cash drawer. Error loading win32com: java.lang.UnsatisfiedLinkError: C:\Program Files\Java\jdk1.6.0_15\jre\bin\win32com.dll: Can't load IA 32-bit .dll on a AMD 64-bit platform The code i am using is as follows `import javax.comm.; import java.util.; /** Check each port to see if it is open. **/ public class openPort { public static void main (String [] args) { Enumeration port_list = CommPortIdentifier.getPortIdentifiers (); while (port_list.hasMoreElements ()) { // Get the list of ports CommPortIdentifier port_id = (CommPortIdentifier) port_list.nextElement (); // Find each ports type and name if (port_id.getPortType () == CommPortIdentifier.PORT_SERIAL) { System.out.println ("Serial port: " + port_id.getName ()); } else if (port_id.getPortType () == CommPortIdentifier.PORT_PARALLEL) { System.out.println ("Parallel port: " + port_id.getName ()); } else System.out.println ("Other port: " + port_id.getName ()); // Attempt to open it try { CommPort port = port_id.open ("PortListOpen",20); System.out.println (" Opened successfully"); port.close (); } catch (PortInUseException pe) { System.out.println (" Open failed"); String owner_name = port_id.getCurrentOwner (); if (owner_name == null) System.out.println (" Port Owned by unidentified app"); else // The owner name not returned correctly unless it is // a Java program.

  • I can't get datepicker to work

    - by vikitor
    Hi, I need a field that displays the datepicker. I followed the example given by the JQuery UI documentation and haven't managed to get it to work. My html where I have my text field is: <div class="editor-field"> <input type = "text" name = "DatePublished" id = "Published" /> <%= Html.ValidationMessage("DatePublished" ,"*") %> </div> This HTML is in a partial view, lets call it pv.ascx, and it is called in the main page as a modal box: <div id = "ModalBox"> <% Html.RenderAction("pv", "Example"); %> </div> The thing is, that I try to call the datepicker creation anytime I enter the main page, and I do it in my javascript file app.js: $().ready(function() { var place = window.location.pathname; var placesplit = place.split("/"); //Depending on the location we are on, we execute different subroutines $('#Published').datepicker(); }); But nothing happens when I focus on the text field. What is wrong? Could it be that being called from a partial view it doesn't work? Thank you everyone, vikitor

  • If statement is ignored

    - by user2898120
    I am making a simple matchmaker as a learning project in JAVA. My program so far just asks a few questions, but I wanted to do gender specific questions, so I asked for their sex (m or f) and then attempted to add a message that only showed if sex was m. The dialog should say "well done, you are male!". Else it restarts method. Every time, no matter what I type it restarts the program. Here is my code: import javax.swing.JOptionPane; public class Main { public static void main(String[] args){ setVars(); } public static void setVars(){ String name = JOptionPane.showInputDialog(null, "What is your name?"); String sAge = JOptionPane.showInputDialog(null, "What is your age?"); String sex = JOptionPane.showInputDialog(null, "What is your sex?\n(Enter m or f)"); if (sex == "m"){ JOptionPane.showMessageDialog(null, "Well done, you are male.\nKeep Going!"); } int age = Integer.parseInt(sAge); String chars = JOptionPane.showInputDialog(null, "Name three charectaristics"); } }

  • How to properly close a UDT server in Netty 4

    - by Steffen
    I'm trying to close my UDT server (Netty 4.0.5.Final) with shutDownGracefully() and reopen it on the same port. Unfortunately, I always get the socket exception below although it waits until the future has completed. I also added the socket option SO_REUSEADDR. What is the proper way to do this?

  • EnvDTE Retrieving the data type from a CodeElement

    - by chrischu
    I am using EnvDTE to generate some code in my latest project. I have a reference to a CodeClass-Object for a given C#-Class but now I wanted to loop through all of its members (in codeClass.Members) and check their types. However I can't manage to retrieve the type of the given member from the CodeElement-Object that I get when looping through codeClass.Members. How can I retrieve the type (int, string etc.)? PS: Reflection is not an option for my usecase.

  • Django sphinx works only after app restart.

    - by Lhiash
    Hi, I've set up django-sphinx in my project, which works perfectly only for some time. Later it always returns empty result set. Surprisingly restarting django app fixes it. And search works again but again only for short time (or very limiter number of queries).

  • How to have a policy class implement a virtual function?

    - by dehmann
    I'm trying to design a policy-based class, where a certain interface is implemented by the policy itself, so the class derives from the policy, which itself is a template (I got this kind of thinking from Alexandrescu's book): #include <iostream> #include <vector> class TestInterface { public: virtual void test() = 0; }; class TestImpl1 { public: void test() {std::cerr << "Impl1" << std::endl;} }; template<class TestPolicy> class Foo : public TestInterface, TestPolicy { }; Then, in the main() function, I call test() on (potentially) various different objects that all implement the same interface: int main() { std::vector<TestInterface*> foos; foos.push_back(new Foo<TestImpl1>()); foos[0]->test(); delete foos[0]; return 0; } It doesn't compile, though, because the following virtual functions are pure within ‘Foo<TestImpl1>’: virtual void TestInterface::test() I thought TestInterface::test() is implemented because we derive from TestImpl1?

  • Firefox and IE - Firefox handling of <span> inside tables (html and css)

    - by jasrpg
    Hello, I am having difficulties getting a span tag to work properly inside a table. It appears as if the entire span tag is being ignored that is defined anywhere in between table tags in firefox, but in IE this shows up correctly. Maybe I am missing something, but I have created a small example css and html file that displays differently in Firefox and IE. Hopefully someone can tell me why it is behaving this way or how I can rearrange the html to resolve the issue in firefox. ---main.css--- .class1 A:link {color:#960033; text-decoration: none} .class1 A:visited {color:#960033; text-decoration: none} .class1 A:hover {color:#0000FF; font-weight: bold; text-decoration: none} .class1 A:active {color:#0000FF; font-weight: bold; text-decoration: none} .class2 A:link {color:#960033; text-decoration: none} .class2 A:visited {color:#960033; text-decoration: none} .class2 A:hover {color:#0000FF; text-decoration: none} .class2 A:active {color:#0000FF; text-decoration: none} ---test.htm--- <HTML> <HEAD> <title>Title Page</title> <style type="text/css">@import url("/css/main.css");</style> </HEAD> <span class="class1"> <BODY> <table><tr><td> ---Insert Hyperlink---<br> </td></tr> </span><span class="class2"> <tr><td> ---Insert Hyperlink---<br> </td></tr></table> </span> </BODY> </HTML>

  • Problem in migrating to LAMP from XAMPP.. Memory limit error

    - by Geshan
    I was using XAMPP for my local machine but as I wanted to run applications like mysql work bench and some test frameworks I decided to switch to LAMP self install. I'm using ubuntu and followed the instructions at: https://help.ubuntu.com/community/ApacheMySQLPHP But the problem is LAMP is consuming too much of my memory (RAM) I've allocated 124 MB currently but still it gives me memory exhausted error when I run Drush (Drupal command line). When I do drush cc to clear cache it give me the following: Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 122880 bytes) in /var/www/----/sites/all/modules/ubercart/uc_order/uc_order.order_pane.inc on line 150 Call Stack: 0.0020 185624 1. {main}() /opt/drush/drush.php:0 0.0254 1303672 2. drush_main() /opt/drush/drush.php:37 0.2674 5107784 3. drush_bootstrap() /opt/drush/drush.php:71 0.2676 5109872 4. _drush_bootstrap_drupal_full() /opt/drush/includes/environment.inc:173 0.2676 5151032 5. drupal_bootstrap() /opt/drush/includes/environment.inc:655 0.3030 7739048 6. _drupal_bootstrap() /var/www/missmoti/includes/bootstrap.inc:989 0.3122 8855792 7. _drupal_bootstrap_full() /var/www/missmoti/includes/bootstrap.inc:1078 0.3445 12387320 8. module_load_all() /var/www/missmoti/includes/common.inc:2608 0.5194 32586544 9. drupal_load() /var/www/missmoti/includes/module.inc:14 0.5251 33361112 10. include_once('/var/www/missmoti/sites/all/modules/ubercart/uc_order/uc_order.module') /var/www/-----/includes/bootstrap.inc:617 Drush command could not be completed.

  • Debugging an unresponsive iPhone UI

    - by buggles
    I have an application that needs to update its display every minute or so. To achieve this I was using performSelector:withObject:afterDelay, calling the selector that most of the time just changes some text in a label based on a very simple (and quick) calculation. [self performSelector:@selector(updateDisplay) withObject:nil afterDelay:60]; Occasionally during an update, I have to go off and get some data from the web, and so I do that in another thread using detachNewThreadSelector. That all worked and the "performSelector after Delay" call completes in a tiny fraction of a second, and only runs once a minute. Despite this, and despite running fine on the simulator, the single button in the app is largely unresponsive, not responding to multiple stabs. So, I had assumed peformSelector:afterDelay would not block, but I'm now wondering if it is blocking in some way? I even tried NOT doing the web-look-up incase this was somehow still impacting the responsiveness. No joy. [NSThread detachNewThreadSelector:@selector(updateFromURL) toTarget:self withObject:nil]; I then pushed it through shark to see if I could see anything obvious. From here I can see the web-lookup is the only thing taking any time, but it is only being done every couple of minutes, and then clearly not running on the main thread. The app itself is consuming a tiny fraction of 1% of the CPU (0.0000034%) over 20 minutes, so it just must be a blocking issue. So, am I missing something about performSelector:afterDelay? What other common newbie mistakes might I be making. If it helps, although I've been developing applications for over 20 years, the previous 10 have been largely Java. Perhaps I have a Java assumption loaded :-) Essentially I have assumed the main thread is like the EDT (only do UI stuff on it, but keep everything else off it).

  • MS Access form_current() firing multiple times

    - by Eric G
    I have a form with two subforms (on separate tab pages). It's an MDB project in Access 2003. When it initially opens, Form_Current on the active subform fires once, as it should. But when you move to another record (ie. from the main form), it fires Form_Current on the active subform 4 times. Then subsequent record-moves result in Form_Current firing 2 times. This is a pain, because the subforms have a lot of fields that get moved and/or hidden and so it jumps around for every Form_Current, not to mention being slow. I am opening the form with a filter via DoCmd.OpenForm (actually it sends the filter in via OpenArgs). FilterOn is only set once, in Form_Open on the main form, never in the subforms. Form_Current is not called explicitly anywhere else in the code. When I look at the call stack when Form_Current fires moving the first time, it looks like: my_subform.Form_Current [<Debug Window>] my_subform.Form_Current So it seems like something in Form_Current is triggering another Form_Current event. But only on the first record move. The code in Form_Current is somewhat complex, involving custom classes and event callbacks, but generally does not touch the table data. The only thing I can think might be triggering a Form_Current is that it checks OldValue on form controls - could this be causing it? Or anything else come to mind? Thanks. Eric

  • Calling webservice via server causes java.net.MalformedURLException: no protocol

    - by Thomas
    I am writing a web-service, which parses an xml file. In the client, I read the whole content of the xml into a String then I give it to the web-service. If I run my web-service with main as a Java-Application (for tests) there is no problem, no error messages. However when I try to call it via the server, I get the following error: java.net.MalformedURLException: no protocol I use the same xml file, the same code (without main), and I just cannot figure out, what the cause of the error can be. here is my code: DOMParser parser=new DOMParser(); try { parser.setFeature("http://xml.org/sax/features/validation", true); parser.setFeature("http://apache.org/xml/features/validation/schema",true); parser.setFeature("http://apache.org/xml/features/validation/dynamic",true); parser.setErrorHandler(new myErrorHandler()); parser.parse(new InputSource(new StringReader(xmlFile))); document=parser.getDocument(); xmlFile is constructed in the client so: String myFile ="C:/test.xml"; File file=new File(myFile); String myString=""; FileInputStream fis=new FileInputStream(file); BufferedInputStream bis=new BufferedInputStream(fis); DataInputStream dis=new DataInputStream(bis); while (dis.available()!=0) { myString=myString+dis.readLine(); } fis.close(); bis.close(); dis.close(); Any suggestions will be appreciated!

  • Are AJAX sites crawlable by search engines?

    - by frankadelic
    I had always assumed that AJAX-driven content was invisible to search engines. (i.e. content inserted into the DOM via XMLHTTPRequest) For example, in this site, the main content is loaded via AJAX request by the browser: http://www.trustedsource.org/query/terra.cl ...if you view this page with Javascript disabled, the main content area is blank. However, Google cache shows the full content after the AJAX load: http://74.125.155.132/search?q=cache:JqcT6EVDHBoJ:www.trustedsource.org/query/terra.cl+http://www.trustedsource.org/query/terra.cl&cd=1&hl=en&ct=clnk&gl=us So, apparently search engines do index content loaded by AJAX. Questions: Is this a new feature in search engines? Most postings on the web indicate that you have to publish duplicate static HTML content for search engines to find them. Are there any tricks to get an AJAX-driven content to be crawled by search engines (besides creating duplicate static HTML content). Will the AJAX-driven content be indexed if it is loaded from a separate subdomain? How about a separate domain?

  • Function that prints something to std::ostream and returns std::ostream?

    - by dehmann
    I want to write a function that outputs something to a ostream that's passed in, and return the stream, like this: std::ostream& MyPrint(int val, std::ostream* out) { *out << val; return *out; } int main(int argc, char** argv){ std::cout << "Value: " << MyPrint(12, &std::cout) << std::endl; return 0; } It would be convenient to print the value like this and embed the function call in the output operator chain, like I did in main(). It doesn't work, however, and prints this: $ ./a.out 12Value: 0x6013a8 The desired output would be this: Value: 12 How can I fix this? Do I have to define an operator<< instead? UPDATE: Clarified what the desired output would be. UPDATE2: Some people didn't understand why I would print a number like that, using a function instead of printing it directly. This is a simplified example, and in reality the function prints a complex object rather than an int.

  • Query notation for the sitecore 'source' field in template builder

    - by M.R.
    I am trying to set the the source field of a template using the query notation (or xpath - whichever works), but none of them seems to be working. My content tree is a multisite content tree: France --Page 1 ----Page1A -------Page1AA --Page 2 --Page 3 --METADATA ----Regions US --Page 1 ----Page1A -------Page1AA --Page 2 --Page 3 --METADATA ----Regions Each site has its own METADATA folder, and I want it so that when adding a page inside each of the main country nodes, I want the values to reflect whatever is in the METADATA of that site. I have two different fields for now - a droplink and a treelistex field. So I thought I can just get the parent item that is a country site, and get the metadata folder for that. When I put the following query in both the fields, I get different results: query:./ancestor::*[@@templatename='CountryHome']/METADATA/Regions/* For the droplink field, I get only the first Region (one item) For the treelistex field, I get the entire content tree I then tried to modify the query a little bit and took the 'query' notation out ./ancestor::*[@@templatename='CountryHome']/METADATA/Regions/* If I go to the developer center/xpath builder, and set the context node to any item underneath the main country site, it returns me exactly what I need, but when I put this in the source, I get the entire content tree in both the cases. Help!

  • ASP.NET MVC on GoDaddy Not Working (Not Primary Domain Deployment)

    - by JPrescottSanders
    I am trying to get ASP.NET MVC working on GoDaddy and I'm not having much luck. I have read the post on SO that covers the subject, but I must have a slightly different configuration or must be missing somehting along the way because the main MVC page comes up, but all links seem to fail and no amount of tweaking the URLs seems to get it to work. A little back ground. I have a single hosting plan with many domains pointed to sub folders of the main domain. Basic ASP.NET web forms pages work just fine, but of course I wanted to try and host a sample MVC site in one of these non-primary domains. You can go to the URL here. As you can see this first page comes up, but if you click on Home or About it doesn't work. Clicking on Home creates this link "http://www.jprescottsanders.com/jps/" and clicking on about creates this link "http://www.jprescottsanders.com/jps/Home/About". As you can see JPS sneaks in there, this of course is the sub folder that i place my web app files in. I would like to know if this is a MVC related issue or a GoDaddy issue. I suspect that MVC may want to sit in the root directory of the site, and when it puts the "jps" into the URLs it breaks the routing mechanisms (but this is conjecture). I know Dan said this was possible so I'm hoping he sees this and helps me get to the bottom of this deployment strategy for MVC.

  • How to insert a child node in a TreeView Control in WPF?

    - by xarzu
    I have a TreeView control that I have created in XAML in a WPF program After adding a couple nodes at the root level, I have written code that loops through the tree structure like so: ItemCollection items = treeView1.Items; foreach (TreeViewItem n in items) { ... } Once I find the place in this loop where I want to include a child node, how do I go about inserting a child?

  • Linking AS code to symbols defined in an external SWC?

    - by Ender
    (apologies ahead of time, I only really know Flash; my Flex experience is basically nil. There may be a very standard and obvious workflow solution that Flex people know about) I have a number of UI elements that are graphically quite complex (they're not components, they're just Sprites). Since it takes a long time to compile them, I've been trying to move them into an external .swc. However, I want to associate some code with these classes, but I don't want to have to recompile the graphical assets every time I make a code change. At the moment I have it set up like this: UI elements are created in a separate FLA and exported to a SWC. In my primary FLA, I have actionscript classes that extend each of the graphical assets in the SWC. For example: external.swc: (some symbol defined in the Library and exported for actionscript in frame 1) class: com.foo.WidgetGraphic base: flash.display.Sprite main.fla: Widget.as: package com.foo { public class Widget extends WidgetGraphic { ... } } This works, but is time-consuming and prone to error. I'd rather be able to avoid having to inherit from each graphical asset, and just define them directly. Is there a better way to do what I'm trying to accomplish? Note: the main concern here is compile time. I don't have any movies or audio or fonts, just a lot of vector art assets that appear to be slowing down my compilation time significantly. When I'm debugging I'm only making code changes, and would rather not have to keep recompiling the art...

  • why pointer to pointer is needed to allocate memory in function

    - by skydoor
    Hi I have a segmentation fault in the code below, but after I changed it to pointer to pointer, it is fine. Could anybody give me any reason? void memory(int * p, int size) { try{ p = (int *) malloc(size*sizeof(int)); } catch( exception& e) { cout<<e.what()<<endl; } } it does not work in the main function as blow int *p = 0; memory(p, 10); for(int i = 0 ; i < 10; i++) p[i] = i; however, it works like this . void memory(int ** p, int size) { `//pointer to pointer` try{ *p = (int *) malloc(size*sizeof(int)); } catch( exception& e) { cout<<e.what()<<endl; } } int main() { int *p = 0; memory(&p, 10); //get the address of the pointer for(int i = 0 ; i < 10; i++) p[i] = i; for(int i = 0 ; i < 10; i++) cout<<*(p+i)<<" "; return 0; }

  • How can I reuse .NET resources in multiple executables?

    - by Brandon
    I have an existing application that I'm supposed to take and create a "mini" version of. Both are localized apps and we would like to reuse the resources in the main application as is. So, here's the basic structure of my apps: MainApplication.csproj /Properties/Resources.resx /MainUserControl.xaml (uses strings in Properties/Resources.resx) /MainUserControl.xaml.cs MiniApplication.csproj link to MainApplication/Properties/Resources.resx link to MainApplication/MainUserControl.xaml link to MainApplication/MainUserControl.xaml.cs MiniApplication.xaml (tries to use MainUserControl from MainApplication link) So, in summary, I've added the needed resources and user control from the main application as links in the mini application. However, when I run the mini application, I get the following exception. I'm guessing it's having trouble with the different namespaces, but how do I fix? Could not find any resources appropriate for the specified culture or the neutral culture. Make sure \"MainApplication.Properties.Resources.resources\" was correctly embedded or linked into assembly \"MiniApplication\" at compile time, or that all the satellite assemblies required are loadable and fully signed. FYI, I know I could put the user control in a user control library but the problem is that the mini application needs to have a small footprint. So, we only want to include what we need.

  • Using repaint() method.

    - by owca
    I'm still struggling to create this game : http://stackoverflow.com/questions/2844190/choosing-design-method-for-ladder-like-word-game .I've got it almost working but there is a problem though. When I'm inserting a word and it's correct, the whole window should reload, and JButtons containing letters should be repainted with different style. But somehow repaint() method for the game panel (in Main method) doesn't affect it at all. What am I doing wrong ? Here's my code: Main: import java.util.Scanner; import javax.swing.*; import java.awt.*; public class Main { public static void main(String[] args){ final JFrame f = new JFrame("Ladder Game"); Scanner sc = new Scanner(System.in); System.out.println("Creating game data..."); System.out.println("Height: "); //setting height of the grid while (!sc.hasNextInt()) { System.out.println("int, please!"); sc.next(); } final int height = sc.nextInt(); /* * I'm creating Grid[]game. Each row of game contains Grid of Element[]line. * Each row of line contains Elements, which are single letters in the game. */ Grid[]game = new Grid[height]; for(int L = 0; L < height; L++){ Grid row = null; int i = L+1; String s; do { System.out.println("Length "+i+", please!"); s = sc.next(); } while (s.length() != i); Element[] line = new Element[s.length()]; Element single = null; String[] temp = null; String[] temp2 = new String[s.length()]; temp = s.split(""); for( int j = temp2.length; j>0; j--){ temp2[j-1] = temp[j]; } for (int k = 0 ; k < temp2.length ; k++) { if( k == 0 ){ single = new Element(temp2[k], 2); } else{ single = new Element(temp2[k], 1); } line[k] = single; } row = new Grid(line); game[L] = row; } //############################################ //THE GAME STARTS HERE //############################################ //create new game panel with box layout JPanel panel = new JPanel(); panel.setLayout(new BoxLayout(panel, BoxLayout.Y_AXIS)); panel.setBackground(Color.ORANGE); panel.setBorder(BorderFactory.createEmptyBorder(10, 10, 10, 10)); //for each row of the game array add panel containing letters Single panel //is drawn with Grid's paint() method and then returned here to be added for(int i = 0; i < game.length; i++){ panel.add(game[i].paint()); } f.setContentPane(panel); f.pack(); f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); f.setVisible(true); boolean end = false; boolean word = false; String text; /* * Game continues until solved() returns true.

  • Jmap can't connect to to make a dump

    - by Jasper Floor
    We have an open beta of an app which occasionally causes the heapspace to overflow. The JVM reacts by going on a permanent vacation. To analyze this I would like to peek into the memory at the point where it failed. Java does not want me to do this. The process is still in memory but it doesn't seem to be recognized as a java process. The server in question is a debian Lenny server, Java 6u14 /opt/jdk/bin# ./jmap -F -dump:format=b,file=/tmp/apidump.hprof 11175 Attaching to process ID 11175, please wait... sun.jvm.hotspot.debugger.NoSuchSymbolException: Could not find symbol "gHotSpotVMTypeEntryTypeNameOffset" in any of the known library names (libjvm.so, libjvm_g.so, gamma_g) at sun.jvm.hotspot.HotSpotTypeDataBase.lookupInProcess(HotSpotTypeDataBase.java:390) at sun.jvm.hotspot.HotSpotTypeDataBase.getLongValueFromProcess(HotSpotTypeDataBase.java:371) at sun.jvm.hotspot.HotSpotTypeDataBase.readVMTypes(HotSpotTypeDataBase.java:102) at sun.jvm.hotspot.HotSpotTypeDataBase.<init>(HotSpotTypeDataBase.java:85) at sun.jvm.hotspot.bugspot.BugSpotAgent.setupVM(BugSpotAgent.java:568) at sun.jvm.hotspot.bugspot.BugSpotAgent.go(BugSpotAgent.java:494) at sun.jvm.hotspot.bugspot.BugSpotAgent.attach(BugSpotAgent.java:332) at sun.jvm.hotspot.tools.Tool.start(Tool.java:163) at sun.jvm.hotspot.tools.HeapDumper.main(HeapDumper.java:77) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at sun.tools.jmap.JMap.runTool(JMap.java:179) at sun.tools.jmap.JMap.main(JMap.java:110) Debugger attached successfully. sun.jvm.hotspot.tools.HeapDumper requires a java VM process/core!
