  • How to set an EditText on top of a ListView ?

    - by Spredzy
    Hi everyone, I am trying to do an autocomplete version my way (logic, layout, etc...) , so I don't want to use the AutoCompleteTextView. My question is how to set an EditText on top of a ListView in a class inheriting from a ListAcvitivy. I tried two kinds of layout, none of them worked. First one : <EditText android:id="@+id/autocomplete_server" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_marginLeft="5dp" android:completionThreshold="1" android:singleLine="true"/> <ListView android:id="@id/android:list" android:layout_width="fill_parent" android:layout_height="fill_parent" android:background="#000000" android:layout_weight="1" android:drawSelectorOnTop="false"/> <TextView android:id="@id/android:empty" android:layout_width="fill_parent" android:layout_height="fill_parent" android:background="#FF0000" android:text="No data"/> This one only shows me the EditText but does not display the list Second one : <LinearLayout android:id="@id/android:list" android:orientation="horizontal" android:layout_width="fill_parent" android:layout_height="wrap_content" android:padding="5dp"> <EditText android:id="@+id/autocomplete_server" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_marginLeft="5dp" android:completionThreshold="1" android:singleLine="true"/> <ListView android:layout_width="fill_parent" android:layout_height="fill_parent" android:background="#000000" android:layout_weight="1" android:drawSelectorOnTop="false"/> </LinearLayout> This sample gives me a : java.lang.RuntimeException: Unable to start activity ComponentInfo{com.eip.core/com.eip.core.Search}: java.lang.ClassCastException: android.widget.LinearLayout Does anyone have any idea bout how to implement an EditText on top of a listView ?

  • Can't find compiled resource bundles

    - by user351032
    I am using Adobe Flash Builder 4. I've run into this issue with my latest project, but I was able to re-create it with an almost empty project. Here is what I've done. Created a new Flex Project Created a locale/en_US folder within this project. Added a class that extends SparkDownloadProgressBar. All this class does is attempt to create a Label. When I try to debug this application, I get the following error. Error: Could not find compiled resource bundle 'components' for locale 'en_US'. at mx.resources::ResourceManagerImpl/installCompiledResourceBundle()[E:\dev\4.0.0\frameworks\projects\framework\src\mx\resources\ResourceManagerImpl.as:340] at mx.resources::ResourceManagerImpl/installCompiledResourceBundles()[E:\dev\4.0.0\frameworks\projects\framework\src\mx\resources\ResourceManagerImpl.as:269] at mx.resources::ResourceManagerImpl/processInfo()[E:\dev\4.0.0\frameworks\projects\framework\src\mx\resources\ResourceManagerImpl.as:387] at mx.resources::ResourceManagerImpl()[E:\dev\4.0.0\frameworks\projects\framework\src\mx\resources\ResourceManagerImpl.as:122] at mx.resources::ResourceManager$/getInstance()[E:\dev\4.0.0\frameworks\projects\framework\src\mx\resources\ResourceManager.as:111] at mx.core::UIComponent()[E:\dev\4.0.0\frameworks\projects\framework\src\mx\core\UIComponent.as:3728] at spark.components.supportClasses::TextBase()[E:\dev\4.0.0\frameworks\projects\spark\src\spark\components\supportClasses\TextBase.as:154] at spark.components::Label()[E:\dev\4.0.0\frameworks\projects\spark\src\spark\components\Label.as:384] at Preloader()[C:\SVN\Games\Social\Test\src\Preloader.as:21] at mx.preloaders::Preloader/initialize()[E:\dev\4.0.0\frameworks\projects\framework\src\mx\preloaders\Preloader.as:253] at mx.managers::SystemManager/http://www.adobe.com/2006/flex/mx/internal::initialize()[E:\dev\4.0.0\frameworks\projects\framework\src\mx\managers\SystemManager.as:1925] at mx.managers::SystemManager/initHandler()[E:\dev\4.0.0\frameworks\projects\framework\src\mx\managers\SystemManager.as:2419] The Flex Compiler/Additional Compiler Arguments section does contain "-locale en_US", but I do not want to just remove this as I am planning to have this load different property files based on the localization region at run-time and how I understand it, I will need to add each locale that I am planning to use on the compile argument line. I am at a loss as to how to attack this problem. If you need anymore information from me to help with this, I will be more than happy to provide it. Thanks ahead of time for the help!

  • MonoDevelop: Addin generation issues

    - by calmcajun
    I am having problems creating the root.mrep file for a updated MonoDevelop Addin. The Addin was originally built for MonoDevelop 2.2. I am able to build the updated project but when I use mdrun.exe setup rep-build to generate the .mrep files(main and root) it only generates the main.mrep file and not the root.mrep file. Is there a new way of building the addin that I am missing? I used both setup pack and then setup rep-build. I have listed a snippet of the addin.xml file below: <Addin id = "Addin" namespace = "MonoDevelop" name = "Monobjc development" author = "Rob L" copyright = "" description = "Addin" category = "Mac Development" version = "1.0"> <Runtime> <Import assembly="MonoDevelop.Sample.dll" /> <Import assembly="MonoDevelop.MacDev.dll" /> <Import assembly="Sample.Tools.dll" /> </Runtime> <Dependencies> <Addin id="Core" version="2.4" /> <Addin id="Core.Gui" version="2.4" /> <Addin id="Projects" version="2.4" /> <Addin id="Projects.Gui" version="2.4" /> <Addin id="Ide" version="2.4" /> </Dependencies> <MoreStuffHere /> </Addin>

  • Reversing Django URLs With Extra Options

    - by Justin Voss
    Suppose I have a URLconf like below, and 'foo' and 'bar' are valid values for page_slug. urlpatterns = patterns('', (r'^page/(?P<page_slug>.*)/', 'myapp.views.someview'), ) Then, I could reconstruct the URLs using the below, right? >>> from django.core.urlresolvers import reverse >>> reverse('myapp.views.someview', kwargs={'page_slug': 'foo'}) '/page/foo/' >>> reverse('myapp.views.someview', kwargs={'page_slug': 'bar'}) '/page/bar/' But what if I change my URLconf to this? urlpatterns = patterns('', (r'^foo-direct/', 'myapp.views.someview', {'page_slug': 'foo'}), (r'^my-bar-page/', 'myapp.views.someview', {'page_slug': 'bar'}), ) I expected this result: >>> from django.core.urlresolvers import reverse >>> reverse('myapp.views.someview', kwargs={'page_slug': 'foo'}) '/foo-direct/' >>> reverse('myapp.views.someview', kwargs={'page_slug': 'bar'}) '/my-bar-page/' However, this throws a NoReverseMatch exception. I suspect I'm trying to do something impossible. Any suggestions on a saner way to accomplish what I want? Named URLs aren't an option, since I don't want other apps that link to these to need to know about the specifics of the URL structure (encapsulation and all that).

  • View Controller's viewDidLoad method finishing before applicationDidFinishLaunching

    - by mwt
    I'm creating a fairly complex iPhone app using Core Data. Up until now, things have been working fine. As the app has been getting more complex, however, a new problem has come up: the first view controller is finishing its viewDidLoad method before the AppDelegate gets even halfway through its applicationDidFinishLaunching method. The view controller is not the root, which is a tab bar controller. The VC in question is the one for the default selected tab on the tab bar. It's getting instantiated by IB. Nothing like this has occurred before in my experience, and it's throwing off the important initialization I'm doing in the AppDelegate (getting objects from Core Data and preparing them for use) . Furthermore, it's intermittent -- sometimes the delegate does finish first. Has anyone else noticed a difficulty like this? Any sample code that deals with such an issue? I suppose that the answer is to make the VC load the data that the AppDelegate is getting ready only when the AppDelegate sends a message that it's ready. I'm a bit concerned that this is adding something that will just end up biting me in the butt later on.

  • Django: A Result Specific Numeration for Pagination.

    - by TheLizardKing
    Simply put I want what http://www.reddit.com/ and http://news.ycombinator.com/ have to the left of every link. A numerated link starting with 1 and continuing to the next page by means of pagination. I really enjoy using generic views and their built-in pagination for Django and it seems to allow me access to these values if I was on page 3 with 2 items per page. {'MEDIA_URL': ''} {'LANGUAGES': '<<languages>>', 'LANGUAGE_BIDI': False, 'LANGUAGE_CODE': 'en-us'} {'debug': True, 'sql_queries': '<<sql_queries>>'} {'messages': [], 'perms': <django.core.context_processors.PermWrapper object at 0xadedeec>, 'user': <User: thelizardking>} {'first_on_page': 5, 'has_next': True, 'has_previous': True, 'hits': 7, 'is_paginated': True, 'last_on_page': 6, 'links_list': [<Link: Funky Town>, <Link: Apple Jax>], 'next': 4, 'page': 3, 'page_obj': <Page 3 of 4>, 'page_range': [1, 2, 3, 4], 'pages': 4, 'paginator': <django.core.paginator.Paginator object at 0xadf914c>, 'previous': 2, 'results_per_page': 2} I know there is an add filter for templates but that's as close as I think I can get and that really doesn't do what I want. Am I going to have to use a custom template filter here or is there something I am not seeing?

  • What does this svn2git error mean?

    I am trying to import my repository from svn to git using svn2git, but it seems like it's failing when it hits a branch. What's the problem?

You are in 'detached HEAD' state. You can look around, make experimental changes and commit them, and you can discard any commits you make in this state without impacting any branches by performing another checkout. If you want to create a new branch to retain commits you create, you may do so (now or later) by using -b with the checkout command again. Example: git checkout -b new_branch_name HEAD is now at f4e6268... Changing svn repository in cap files Running command: git branch -D master Deleted branch master (was f4e6268).

  • How to use 3rd party libraries in glassfish?

    - by Hank
    I need to connect to a MongoDB instance from my EJB3 application, running on glassfish 3.0.1. The Mongo project provides a set of drivers, and I'm able to use them in a standalone Java application. How would I use them in a JEE application? Or maybe better phrasing: how would I make a 3rd party library available to my application when it runs in an EJB container? At the moment, I'm getting a java.lang.NoClassDefFoundError when deploying a bean that tries to import from the library: [#|2010-03-24T11:42:15.164+0100|SEVERE|glassfishv3.0|global|_ThreadID=28;_ThreadName=Thread-1;|Class [ com/mongodb/DBObject ] not found.

Do I need to 'register' the library with the container? Reference it via Annotation? Extend the classpath of the container to include the library?

  • How do I test OpenCL on GPU when logged in remotely on Mac?

    - by Christopher Bruns
    My OpenCL program can find the GPU device when I am logged in at the console, but not when I am logged in remotely with ssh. Further, if I run the program as root in the ssh session, the program can find the GPU. The computer is a Snow Leopard Mac with a GeForce 9400 GPU. If I run the program (see below) from the console or as root, the output is as follows (notice the "GeForce 9400" line): 2 devices found Device #0 name = GeForce 9400 Device #1 name = Intel(R) Core(TM)2 Duo CPU P8700 @ 2.53GHz but if it is just me, over ssh, there is no GeForce 9400 entry: 1 devices found Device #0 name = Intel(R) Core(TM)2 Duo CPU P8700 @ 2.53GHz I would like to test my code on the GPU without having to be root. Is that possible? Simplified GPU finding program below: #include <stdio.h> #include <OpenCL/opencl.h> int main(int argc, char** argv) { char dname[500]; size_t namesize; cl_device_id devices[10]; cl_uint num_devices; int d; clGetDeviceIDs(0, CL_DEVICE_TYPE_ALL, 10, devices, &num_devices); printf("%d devices found\n", num_devices); for (d = 0; d < num_devices; ++d) { clGetDeviceInfo(devices[d], CL_DEVICE_NAME, 500, dname, &namesize); printf("Device #%d name = %s\n", d, dname); } return 0; } EDIT: I found essentially the same question being asked on nvidia's forums. Unfortunately, the only answer was of the form "this is the wrong forum".

  • Hibernate - query caching/second level cache does not work by value object containing subitems

    - by Zoltan Hamori
    Hi! I have been struggling with the following problem: I have a value object containing different panels. Each panel has a list of fields. Mapping: <class name="com.aviseurope.core.application.RACountryPanels" table="CTRY" schema="DBDEV1A" where="PEARL_CTRY='Y'" lazy="join"> <cache usage="read-only"/> <id name="ctryCode"> <column name="CTRY_CD_ID" sql-type="VARCHAR2(2)" not-null="true"/> </id> <bag name="panelPE" table="RA_COUNTRY_MAPPING" fetch="join" where="MANDATORY_FLAG!='N'"> <key column="COUNTRY_LOCATION_ID"/> <many-to-many class="com.aviseurope.core.application.RAFieldVO" column="RA_FIELD_MID" where="PANEL_ID='PE'"/> </bag> </class> I use the following criteria to get the value object: Session m_Session = HibernateUtil.currentSession(); m_Criteria = m_Session.createCriteria(RACountryPanels.class); m_Criteria.add(Expression.eq("ctryCode", p_Country)); m_Criteria.setCacheable(true); As I see the query cache contains only the main select like select * from CTRY where ctry_cd_id=? Both RACountryPanels and RAFieldVO are second level cached. If I check the 2nd level cache content I can see that it cointains the RAFields and the RACountryPanels as well and I can see the select .. from CTRY where ctry_cd_id=... in query cache region as well. When I call the servlet it seems that it is using the cache, but second time not. If I check the content of the cache using JMX, everything seems to be ok, but when I measure the object access time, it seems that it does not always use the cache. Cheers Zoltan

    I'm getting following exception when open my GWT app in development mode. the exact same code can compile successfully using mvn gwt:compile Caused by: java.lang.ArrayIndexOutOfBoundsException: 3667 at com.google.gwt.dev.asm.ClassReader.readClass(ClassReader.java:1976) at com.google.gwt.dev.asm.ClassReader.accept(ClassReader.java:464) at com.google.gwt.dev.asm.ClassReader.accept(ClassReader.java:420) at com.google.gwt.dev.shell.rewrite.HasAnnotation.hasAnnotation(HasAnnotation.java:45) at com.google.gwt.dev.shell.CompilingClassLoader.findClass(CompilingClassLoader.java:1100) at com.google.gwt.dev.shell.CompilingClassLoader.loadClass(CompilingClassLoader.java:1203) at java.lang.ClassLoader.loadClass(ClassLoader.java:247) at java.lang.Class.forName0(Native Method) at java.lang.Class.forName(Class.java:247) at com.google.gwt.dev.shell.ModuleSpace.loadClassFromSourceName(ModuleSpace.java:665) at com.google.gwt.dev.shell.ModuleSpace.rebindAndCreate(ModuleSpace.java:468) at com.google.gwt.dev.shell.GWTBridgeImpl.create(GWTBridgeImpl.java:49) at com.google.gwt.core.shared.GWT.create(GWT.java:57) at com.google.gwt.core.client.GWT.create(GWT.java:85) at ... I overdid ModuleSpace.java and printed out the class name at line 665 before Class.forName() which points out it is trying to load the generated GinjectorImpl.java I found out my generated GinjectorImpl.java is about 9MB and with 100K+ lines of code. When I randomly remove some modules from my GWT app it works again, so I'm guessing it is too large for ASM to compile. Any suggestions?

  • Serious Application Error

    - by Garry
    I have a TableView controller class that uses a fetched results controller to display a list of 'patient' entities taken from a Core Data model. The sections of this table are taken from a patient attribute called 'location'. Here is the sort descriptor for the fetch request: NSSortDescriptor *locationDescriptor = [[NSSortDescriptor alloc] initWithKey:@"location" ascending:YES]; NSSortDescriptor *lastNameDescriptor = [[NSSortDescriptor alloc] initWithKey:@"lastName" ascending:YES]; NSArray *sortDescriptors = [[NSArray alloc] initWithObjects:locationDescriptor, lastNameDescriptor, nil]; Here is the initialisation code for the FRC: NSFetchedResultsController *aFetchedResultsController = [[NSFetchedResultsController alloc] initWithFetchRequest:fetchRequest managedObjectContext:managedObjectContext sectionNameKeyPath:@"location" cacheName:@"List"]; When I want to add a new 'patient' entity - I click an add button which then pushes an 'add new patient' view controller to the navigation stack. The first patient I add works fine. If I add a second patient - the app will sometimes crash with the following error: 2010-03-22 14:42:05.270 Patients[1126:207] Serious application error. Exception was caught during Core Data change processing: * -[NSCFArray insertObject:atIndex:]: index (1) beyond bounds (1) with userInfo (null) 2010-03-22 14:42:05.272 Patients[1126:207] Terminating app due to uncaught exception 'NSRangeException', reason: '** -[NSCFArray insertObject:atIndex:]: index (1) beyond bounds (1)' This only seems to happen if the patient's have a location added (if none is added then the location defaults to 'unknown'). It seems to have something to do with the sorting of the location too. For instance, if the first patient location = ward 14 and the second = ward 9 then it crashes without fail. I'm wondering if this is something to do with how I am asking the fetched results controller to sort the section names?? This bug is driving me nuts and I just can't figure it out. Any help would be greatly appreciated!

  • "import numpy" tries to load my own package

    - by Sebastian
    I have a python (2.7) project containing my own packages util and operator (and so forth). I read about relative imports, but perhaps I didn't understand. I have the following directory structure: top-dir/ util/__init__.py (empty) util/ua.py util/ub.py operator/__init__.py ... test/test1.py The test1.py file contains #!/usr/bin/env python2 from __future__ import absolute_import # removing this line dosn't change anything. It's default functionality in python2.7 I guess import numpy as np It's fine when I execute test1.py inside the test/ folder. But when I move to the top-dir/ the import numpy wants to include my own util package: Traceback (most recent call last): File "tests/laplace_2d_square.py", line 4, in <module> import numpy as np File "/usr/lib/python2.7/site-packages/numpy/__init__.py", line 137, in <module> import add_newdocs File "/usr/lib/python2.7/site-packages/numpy/add_newdocs.py", line 9, in <module> from numpy.lib import add_newdoc File "/usr/lib/python2.7/site-packages/numpy/lib/__init__.py", line 4, in <module> from type_check import * File "/usr/lib/python2.7/site-packages/numpy/lib/type_check.py", line 8, in <module> import numpy.core.numeric as _nx File "/usr/lib/python2.7/site-packages/numpy/core/__init__.py", line 45, in <module> from numpy.testing import Tester File "/usr/lib/python2.7/site-packages/numpy/testing/__init__.py", line 8, in <module> from unittest import TestCase File "/usr/lib/python2.7/unittest/__init__.py", line 58, in <module> from .result import TestResult File "/usr/lib/python2.7/unittest/result.py", line 9, in <module> from . import util File "/usr/lib/python2.7/unittest/util.py", line 2, in <module> from collections import namedtuple, OrderedDict File "/usr/lib/python2.7/collections.py", line 9, in <module> from operator import itemgetter as _itemgetter, eq as _eq ImportError: cannot import name itemgetter The troublesome line is either from . import util or perhaps from operator import itemgetter as _itemgetter, eq as _eq What can I do?

  • Hudson plugin, Java error "... disagree on InnerClasses attribute"

    - by StackedCrooked
    I am trying to be able to step through the code of a Hudson plugin called SVNPublisher. I checked out the code for SVNPublisher, used Netbeans to open the project, and clicked "Debug Main project". This results in a Firefox window opening address http://localhost:8080 which shows the Hudson main page. Clicking the "New Job" link results in an error page: HTTP ERROR: 500 jar:file:/home/francis/svn/svnpublisher/target/work/webapp/WEB-INF/lib/hudson-core-1.319.jar!/lib/hudson/newFromList/form.jelly:43:47: <j:forEach> hudson.scm.SubversionTagAction and hudson.scm.SubversionTagAction$DescriptorImpl disagree on InnerClasses attribute RequestURI=/newJob Caused by: org.apache.commons.jelly.JellyTagException: jar:file:/home/francis/svn/svnpublisher/target/work/webapp/WEB-INF/lib/hudson-core-1.319.jar!/lib/hudson/newFromList/form.jelly:43:47: hudson.scm.SubversionTagAction and hudson.scm.SubversionTagAction$DescriptorImpl disagree on InnerClasses attribute at org.apache.commons.jelly.impl.TagScript.handleException(TagScript.java:713) at org.apache.commons.jelly.impl.TagScript.run(TagScript.java:282) at org.apache.commons.jelly.impl.ScriptBlock.run(ScriptBlock.java:95) ...

  • Using git submodules in a git-svn project

    - by Matthias
    In our git-svn managed project, we have 3 upstream projects that are all kept in native git repositories on GitHub. Since the source code of those upstream projects is under our control and changes frequently, our current solution, namely re-deploying the build artifacts to the super-project everytime we change something is quite cumbersome. What I'd like to have is this: parent project (git-svn): --> submodule 1 (git) --> submodule 2 (git) --> submodule 3 (git) That way, the source code for submodules 1-3 is compiled along with the sources for the super project, but I can push changes to submodules separately. The question is: what happens when I git svn dcommit on the parent project? Does this even work? UPDATE Hm, I just set up a simple project structure, trying to resemble this scenario, and I receive this error message when trying to dcommit on the superproject: a0301b11f3544a1e71067ff270eded65e4c8afbd doesn't exist in the repository at /opt/local/libexec/git-core/git-svn line 4775 Failed to read object a0301b11f3544a1e71067ff270eded65e4c8afbd at /opt/local/libexec/git-core/git-svn line 574 Any ideas/suggestions?

  • Retrieving image from database using Ajax

    - by ama
    I'm trying to read image from database with Ajax, but I could not read the xmlhttp.responseText to the img src. The image is saved as binary data in database and also retrieved as binary data. I'm using Ajax in JSP, because I want to give the user the ability to upload images and I will view the last uploaded image, on mouse over action the Ajax will be activated and get the image back, the problem is in reading the img from the response. This is the Ajax function: function ajaxFunction(path) { if (xmlhttp) { var s = path; xmlhttp.open("GET", s, true); xmlhttp.onreadystatechange = handleServerResponse; xmlhttp.send(null); } } function handleServerResponse() { if (xmlhttp.readyState == 4) { var Image = document.getElementById(Image_Element_Name); document.getElementById(Image_Element_Name).src = "data:" + xmlhttp.responseText; } } I also got exception in the server: 10415315 [TP-Processor1] WARN core.MsgContext - Error sending end packet java.net.SocketException: Broken pipe at java.net.SocketOutputStream.socketWrite0(Native Method) at java.net.SocketOutputStream.socketWrite(SocketOutputStream.java:92) at java.net.SocketOutputStream.write(SocketOutputStream.java:136) at org.apache.jk.common.ChannelSocket.send(ChannelSocket.java:537) at org.apache.jk.common.JkInputStream.endMessage(JkInputStream.java:127) at org.apache.jk.core.MsgContext.action(MsgContext.java:302) at org.apache.coyote.Response.action(Response.java:183) at org.apache.coyote.Response.finish(Response.java:305) at org.apache.catalina.connector.OutputBuffer.close(OutputBuffer.java:281) at org.apache.catalina.connector.Response.finishResponse(Response.java:478) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:154) at org.apache.jk.server.JkCoyoteHandler.invoke(JkCoyoteHandler.java:200) at org.apache.jk.common.HandlerRequest.invoke(HandlerRequest.java:283) at org.apache.jk.common.ChannelSocket.invoke(ChannelSocket.java:773) at org.apache.jk.common.ChannelSocket.processConnection(ChannelSocket.java:703) at org.apache.jk.common.ChannelSocket$SocketConnection.runIt(ChannelSocket.java:895) at org.apache.tomcat.util.threads.ThreadPool$ControlRunnable.run(ThreadPool.java:685) at java.lang.Thread.run(Thread.java:619) 10415316 [TP-Processor1] WARN common.ChannelSocket - processCallbacks status 2

  • JVM segmentation faults due to "Invalid memory access of location"

    - by Dan
    I have a small project written in Scala 2.9.2 with unit tests written using ScalaTest. I use SBT for compiling and running my tests. Running sbt test on my project makes the JVM segfault regularly, but just compiling and running my project from SBT works fine. Here is the exact error message: Invalid memory access of location 0x8 rip=0x10959f3c9 [1] 11925 segmentation fault sbt I cannot locate a core dump anywhere, but would be happy to provide it if it can be obtained. Running java -version results in this: java version "1.6.0_37" Java(TM) SE Runtime Environment (build 1.6.0_37-b06-434-11M3909) Java HotSpot(TM) 64-Bit Server VM (build 20.12-b01-434, mixed mode) But I've also got Java 7 installed (though I was never able to actually run a Java program with it, afaik). Another issue that may be related: some of my test cases contain titles including parentheses like ( and ). SBT or ScalaTest (not sure) will consequently insert square parens in the middle of the output. For example, a test case with the name (..)..(..) might suddenly look like (..[)..](..). Any help resolving these issues is much appreciated :-) EDIT: I installed the Java 7 JDK, so now java -version shows the right thing: java version "1.7.0_07" Java(TM) SE Runtime Environment (build 1.7.0_07-b10) Java HotSpot(TM) 64-Bit Server VM (build 23.3-b01, mixed mode) This also means that I now get a more detailed segfault error and a core dump: # # A fatal error has been detected by the Java Runtime Environment: # # SIGSEGV (0xb) at pc=0x000000010a71a3e3, pid=16830, tid=19459 # # JRE version: 7.0_07-b10 # Java VM: Java HotSpot(TM) 64-Bit Server VM (23.3-b01 mixed mode bsd-amd64 compressed oops) # Problematic frame: # V [libjvm.dylib+0x3cd3e3] And the dump.

  • Publishing my Website to my Local Disk Causes Exceptions to show Paths including my Local Disk

    - by coffeeaddict
    I've published my website many times. But didn't think about this though until I came across this issue. So I decided to publish my WAP project to a local folder on my C drive first. Then used FTP to upload it to my shared host on discountasp.net. I noticed during runtime that the stack trace was referencing that local folder still and erroring out. Anyone know what config settings are affected when publishing? Obviously something is still pointing to my local C drive and I've searched my entire solution and don't see why. Here's the runtime error I get when my code tries to run in discountasp.net's web server Cannot write into the public directory - check permissions 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: ScrewTurn.Wiki.PluginFramework.InvalidConfigurationException: Cannot write into the public directory - check permissions Source Error: An unhandled exception was generated during the execution of the current web request.
