  • installed ubuntu 13.04 but no wireless or wired connection available

    - by James
    after having installed ubuntu 13.04 i can not connect to the internet wirelessly or wired? can only connect to internet by using "try ubuntu" via ethernet cable, ive tried seeking help in so many different ways yet getting no positive outcome at all, will someone please explain why i can only connect with ethernet while i have the cd in the tray? ive also tried downloading b43 drivers to connect to the internet but apparently i dont have enough disk space, what is going on here? i have the disk in the tray now at the screen where you can either try or install, if someone could give me a step by step from here it would probably cut out all this hassle of me not knowing whats going on

  • Java.net Reborn

    - by Bob Rhubart
    Java.net, the home of  Java community projects, has been re-launched with a new look and new tools for developers.  The move from CollabNet to the Kenai infrastructure offers more flexibility for developers who want to host or contribute to community projects.  Instead of the large, fixed infrastructure per project (for example, several mailing lists per project), Kenai's ala carte features allow users to take only what they need. "We will continue to have the great mix of blogs, forums, and editorial content as well as new tools on the project side, including Mercurial, Git, and JIRA for developers," Java.net Community Manager Sonya Barry explains.  The migration was huge effort. Over 1400 projects were migrated (and some 30 projects are left to go). A large part of the migration was a big cleanup of abandoned projects. With the high abandonment rate of open source projects, the was a lot to remove. The new java.net site is smaller, faster and now the percentage of good, current content is much higher.

  • No network connectivity (not wired or wireless) - RT5390

    - by Ben Udy
    I am starting to think I simply need to accept a small loss and sell my new ASUS K73E. Because I really don't enjoy computing when I have to deal with Windough$ and this windows 7 64 bit on my new ASUS is even worse than the old machines with XP. I have written to ASUS and they simply say "We don't support Linux" and while Ralink's website says they do support Linux I can't get anyone to tell me what model Ralink card might be in my machine. Is anyone out there who might be able to give me some useful advice???? Here is the answer to command lspci nn && lsusb && lsmod && rfkill list all: di,snd_seq snd 54244 16 snd_hda_codec_realtek,snd_hda_intel,snd_hda_codec,snd_hwdep,snd_pcm_oss,snd_mixer_oss,snd_pcm,snd_seq_oss,snd_rawmidi,snd_seq,snd_timer,snd_seq_device uvcvideo 57374 0 videodev 34361 1 uvcvideo v4l1_compat 13251 2 uvcvideo,videodev soundcore 6620 1 snd snd_page_alloc 7076 2 snd_hda_intel,snd_pcm psmouse 63677 0 serio_raw 3978 0 lp 7028 0 parport 32635 2 ppdev,lp fbcon 35102 71 tileblit 1999 1 fbcon font 7557 1 fbcon bitblit 4707 1 fbcon softcursor 1189 1 bitblit video 17375 0 output 1871 1 video vga16fb 11385 1 vgastate 8961 1 vga16fb ahci 32360 2 di,snd_seq snd 54244 16 snd_hda_codec_realtek,snd_hda_intel,snd_hda_codec,snd_hwdep,snd_pcm_oss,snd_mixer_oss,snd_pcm,snd_seq_oss,snd_rawmidi,snd_seq,snd_timer,snd_seq_device uvcvideo 57374 0 videodev 34361 1 uvcvideo v4l1_compat 13251 2 uvcvideo,videodev soundcore 6620 1 snd snd_page_alloc 7076 2 snd_hda_intel,snd_pcm psmouse 63677 0 serio_raw 3978 0 lp 7028 0 parport 32635 2 ppdev,lp fbcon 35102 71 tileblit 1999 1 fbcon font 7557 1 fbcon bitblit 4707 1 fbcon softcursor 1189 1 bitblit video 17375 0 output 1871 1 video vga16fb 11385 1 vgastate 8961 1 vga16fb ahci 32360 2 Edit #2 lspci 00:00.0 Host bridge: Intel Corporation Device 0104 (rev 09) 00:02.0 VGA compatible controller: Intel Corporation Device 0116 (rev 09) 00:16.0 Communication controller: Intel Corporation Cougar Point HECI Controller #1 (rev 04) 00:1a.0 USB Controller: Intel Corporation Cougar Point USB Enhanced Host Controller #2 (rev 05) 00:1b.0 Audio device: Intel Corporation Cougar Point High Definition Audio Controller (rev 05) 00:1c.0 PCI bridge: Intel Corporation Cougar Point PCI Express Root Port 1 (rev b5) 00:1c.1 PCI bridge: Intel Corporation Cougar Point PCI Express Root Port 2 (rev b5) 00:1c.5 PCI bridge: Intel Corporation Cougar Point PCI Express Root Port 6 (rev b5) 00:1d.0 USB Controller: Intel Corporation Cougar Point USB Enhanced Host Controller #1 (rev 05) 00:1f.0 ISA bridge: Intel Corporation Device 1c49 (rev 05) 00:1f.2 SATA controller: Intel Corporation Cougar Point 6 port SATA AHCI Controller (rev 05) 00:1f.3 SMBus: Intel Corporation Cougar Point SMBus Controller (rev 05) 02:00.0 Network controller: RaLink Device 5390 03:00.0 Ethernet controller: Atheros Communications Device 1083 (rev c0) lsusb Bus 002 Device 002: ID 8087:0024 Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 001 Device 003: ID 13d3:5710 IMC Networks Bus 001 Device 002: ID 8087:0024 Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Thanks for the suggestion because this gave me a model for Ralink RT5390.

  • How to troubleshoot a wireless networking regression?

    - by fluteflute
    I've been experiencing this perhaps slightly odd bug. It works flawlessly in Lucid, but not in Maverick and Natty. I find it seems to work when I'm booting a partition everyday (as I do for my main 10.10 partition) but for my 11.04 testing partition it's a real pain - usually refusing to connect. So given that I have both a working (10.04) and not-working (10.10 and 11.04) installs, how can I troubleshoot my problem?

  • Cisco Linksys AE2500 wireless adapter not working

    - by makuto
    I have a Cisco AE2500 I've used with my laptop to get internet. I had to install the drivers by following this forum: http://ubuntuforums.org/showthread.php?t=1805830 But now the blue light on the adapter doesn't turn on at all, but ndiswrapper reports it is connected. I have no connection to the internet on my laptop, and the adapter doesn't show it's blue light on any of the USB ports of my computer or on the 4 port hub I have. Is there some way I can reset something so that the blue light will show again? I'm using Ubuntu 11.10 on a Dell Latitude D505 laptop. EDIT: I deleted and reinstalled the same exact driver and everything worked again.

  • Bridge Laptop's Ethernet to Wireless

    - by Kalphiter
    The laptop wirelessly connects to my router, while the desktop is connected to the laptop with an ethernet wire. The desktop successfully can use the internet if I set the connection to be shared on the laptop. The problem is, I need the laptop to forward the desktop's packets across the link unmodified, so the desktop is on the same network as the router. The desktop needs its IP assigned by the router, so that I can access it from another computer as "192.168.1.8".

  • Wireless USB Adapter driver configuration

    - by Jones
    First I would like agree one thing that this is fully for Ubuntu, not for BackTrack. However I'm posting my BackTrack question here since I find similar problems in backtrack forum are being unanswered and Linux/Unix site of StackExchange has very low attraction. I'm having USB wifi adapter (iBall Baton), having chipset RTL8191SU. It displays available wifi networks in Wicd manager. But while trying to connect it gives me bad password. When I'm trying to run airmon-ng it didn't returned me the monitor mode. I tried to replace with Ubuntu 12.10 drivers. But it totally nulled the device functionality. However I restored the drivers. I'm interested to compile drivers as if anyone indicate the methods. Awaiting ideas!

  • Help setting up wireless in Ubuntu 13.04

    - by James
    I'm having problems connecting my WIFI in Ubuntu 13.04 . So I was wondering if filling in the data manually ie: the IPv4, IPv6, the SSID and BSSID info etc. I did try this before but maybe I put in the wrong data or maybe not enough. Would that make it work? I just don't know how to find out some of the data you need to put in? I'm new and it's confusing. Does anyone know the solution?

  • Really slow wireless internet on 12.04 with HP dv6 6070ca

    - by Joe
    I was recently running the previous version of Ubuntu through Wine, and everything was working great. I decided to upgrade to pangolin when I saw it came out. After upgrading the internet was very slow (the estimated time on the updates was something like 4 days). I thought maybe this had something to do with the Wine installation, so I decided to finally do an actual dual boot. I partitioned my drive all nice and neat, but I made the mistake of connecting to the internet for the installation, and clicking the option to install updates and restricted extras. This was in the morning, circa 6 am. Fast forward to the evening, the installation is frozen at around 75%. In frustration I gave the ol girl a hard shut-down, which effectively rendered my machine useless. I used the thumb drive to reinstall Ubuntu, this time without connecting to the internet. Installed nice and easy, no problems, but the internet is still ridiculously slow. It took me about 20 minutes of frustration and hitting stop and reload repeatedly to even get this question page to open. This is important to me as now Windows won't even boot and I have to use ubuntu for the time being but I can't even bear to turn on my laptop due to the frustration that immediately ensues. Please help! Oh, and I'm relatively new so if there are some terminal commands that spew out info you guys would find useful let me know what they are and I'll post back the information.

  • How You Helped Shape Java EE 7...

    - by reza_rahman
    I have been working with the JCP in various roles since EJB 3/Java EE 5 (much of it on my own time), eventually culminating in my decision to accept my current role at Oracle (despite it's inevitable set of unique challenges, a role I find by and large positive and fulfilling). During these years, it has always been clear to me that pretty much everyone in the JCP genuinely cares about openness, feedback and developer participation. Perhaps the most visible sign to date of this high regard for grassroots level input is a survey on Java EE 7 gathered a few months ago. The survey was designed to get open feedback on a number of critical issues central to the Java EE 7 umbrella specification including what APIs to include in the standard. When we started the survey, I don't think anyone was certain what the level of participation from developers would really be. I also think everyone was pleasantly surprised that a large number of developers (around 1100) took the time out to vote on these very important issues that could impact their own professional life. And it wasn't just a matter of the quantity of responses. I was particularly impressed with the quality of the comments made through the survey (some of which I'll try to do justice to below). With Java EE 7 under our belt and the horizons for Java EE 8 emerging, this is a good time to thank everyone that took the survey once again for their thoughts and let you know what the impact of your voice actually was. As an aside, you may be happy to know that we are working hard behind the scenes to try to put together a similar survey to help kick off the agenda for Java EE 8 (although this is by no means certain). I'll break things down by the questions asked in the survey, the responses and the resulting change in the specification. APIs to Add to Java EE 7 Full/Web Profile The first question in the survey asked which of four new candidate APIs (WebSocket, JSON-P, JBatch and JCache) should be added to the Java EE 7 Full and Web profile respectively. Developers by and large wanted all the new APIs added to the full platform. The comments expressed particularly strong support for WebSocket and JCache. Others expressed dissatisfaction over the lack of a JSON binding (as opposed to JSON processing) API. WebSocket, JSON-P and JBatch are now part of Java EE 7. In addition, the long-awaited Java EE Concurrency Utilities API was also included in the Full Profile. Unfortunately, JCache was not finalized in time for Java EE 7 and the decision was made not to hold up the Java EE release any longer. JCache continues to move forward strongly and will very likely be included in Java EE 8 (it will be available much sooner than Java EE 8 to boot). An emergent standard for JSON-B is also a strong possibility for Java EE 8. When it came to the Web Profile, developers were supportive of adding WebSocket and JSON-P, but not JBatch and JCache. Both WebSocket and JSON-P are now part of the Web Profile, now also including the already popular JAX-RS API. Enabling CDI by Default The second question asked whether CDI should be enabled in Java EE by default. The overwhelming majority of developers supported the default enablement of CDI. In addition, developers expressed a desire for better CDI/Java EE alignment (with regards to EJB and JSF in particular). Some developers expressed legitimate concerns over the performance implications of enabling CDI globally as well as the potential conflict with other JSR 330 implementations like Spring and Guice. CDI is enabled by default in Java EE 7. Respecting the legitimate concerns, CDI 1.1 was very careful to add additional controls around component scanning. While a lot of work was done in Java EE 6 and Java EE 7 around CDI alignment, further alignment is under serious consideration for Java EE 8. Consistent Usage of @Inject The third question was around using CDI/JSR 330 @Inject consistently vs. allowing JSRs to create their own injection annotations (e.g. @BatchContext). A majority of developers wanted consistent usage of @Inject. The comments again reflected a strong desire for CDI/Java EE alignment. A lot of emphasis in Java EE 7 was put into using @Inject consistently. For example, the JBatch specification is focused on using @Inject wherever possible. JAX-RS remains an exception with it's existing custom injection annotations. However, the JAX-RS specification leads understand the importance of eventual convergence, hopefully in Java EE 8. Expanding the Use of @Stereotype The fourth question was about expanding CDI @Stereotype to cover annotations across Java EE beyond just CDI. A solid majority of developers supported the idea of making @Stereotype more universal in Java EE. The comments maintained the general theme of strong support for CDI/Java EE alignment Unfortunately, there was not enough time and resources in Java EE 7 to implement this fairly pervasive feature. However, it remains a serious consideration for Java EE 8. Expanding Interceptor Use The final set of questions was about expanding interceptors further across Java EE. Developers strongly supported the concept. Along with injection, interceptors are now supported across all Java EE 7 components including Servlets, Filters, Listeners, JAX-WS endpoints, JAX-RS resources, WebSocket endpoints and so on. I hope you are encouraged by how your input to the survey helped shape Java EE 7 and continues to shape Java EE 8. Participating in these sorts of surveys is of course just one way of contributing to Java EE. Another great way to stay involved is the Adopt-A-JSR Program. A large number of developers are already participating through their local JUGs. You could of course become a Java EE JSR expert group member or observer. You should stay tuned to The Aquarium for the progress of Java EE 8 JSRs if that's something you want to look into...

  • Broadcom 4365 wireless driver on 12.04 with 3.4 / 3.5 kernel

    - by zaid
    I used this package to install the driver on 3.2 Kernel and it was working perfectly. Unfortunately the system used to freeze randomly with 3.2 kernel so I installed 3.4 kernel, now there is no freezing, the only problem is that my wifi card is not working, I tried to re-install the package, but didn't work. I can see the driver in the "additional drivers" and it say that it is active, but when I execute iwconfig it doesn't show up. I've even tried ndiswraper and that didn't work either. my lspci: 01:00.0 Network controller: Broadcom Corporation Device 4365 (rev 01)

  • Pppoe wireless connection, Ubuntu 12.4

    - by Barbara
    I recently bought a new computer (Asus 1015 cx) with Ubuntu (12.4) as preinstalled system. My problem is with the internet. The computer connects just fine to the free wifi we have at home, but in college, we have a little bit different system. There is wifi, but it is not free - everyone receives a user name and a password. I cant manage to estabilish this Pppoe connection - the computer "sees" where can it connect, but I dont know where to write my username and password. It is not the DSL connection, what I have already tried. Can you help me?

  • 12.10 Wireless networking

    - by user108594
    I downloaded ubuntu 12.10 using WUBI and cannot connect to the internet. I removed it and downloaded ubuntu 12.04 still cannot connect. This I assume rules out the program being the problem. I reinstalled 12.10. When loaded I get the same message W/red (x) stating Internet not connected. I went to the Settings drop down box and it does not reveal the network list but (enable networking has a ck mark). Am running a HP Laptop with a w/7/64 OS that has a kill switch that indicates (orangeno connection) I downloaded 12.10 on my desktop (on the same network) and everything OK. I tried to follow the instructions in the help menu but got lost and confused . Sincerely Dan Additional Info per request Broadcom 802.11b/g Wlan Internal pc [hp laptop] P.S. I've been out of town for about a month. TKS for your gitback I did install 12.10 via cd and everything ok,but retried alongside 7 and unable to connect to internet,also took laptop and hard wired using ethernet cable and everything ok. stumped again and running out of ideas!!!

  • Getting wireless to work on Ubuntu 11.10 (on a mac machine)

    - by yayu
    I have a 2008 white 13.3 inch macbook that now solely runs ubuntu. However, I cannot get wifi or cable to work on it. Regarding the cable, it atleast tries to connect but eventually disconnects from the wired network. Here is the output for lspci (pastebin) I tried installing b43-fwcutter and firmware-b43 but get errors. (I loaded them from a thumb drive and tried sudo dpkg -i). I cannot understand these instructions from the documentation, as I cannot locate the pool directory. b43-fwcutter is located on the Ubuntu install media under ../pool/main/b/b43-fwcutter/ and patch is located under ../pool/main/p/patch/ or both in the official repositories online. Note: In some versions (10.04 and 11.04 at least) there is not a /pool/main/p/patch/ If this file is missing then you don't need it. In this case you only need to install /pool/main/b/b43-fwcutter by following the instructions below.

  • Ubuntu 12.04 - no wireless network recognized

    - by Itai
    I just installed Ubntu 12.04 along with WIN7 on the same laptop - Dell Vostro-3560. Now, on Win7 i can access to different wi-fi networks. However, when i am logging onto the Ubuntu section (after re-starting my laptop) - an error message appears: "Disconnected - you are now offline". When i take a look at my network menu (in the upper bar on the screen), i see that no network is found (and i have a few of them in the area...). I tried to look around but really could not find a concrete practical solution to this specific problem, would appreciate any solution from anyone out there that had this problem and solved it. Thanks... Itai

  • Lubuntu 13.10 - Laptop Loses wireless after sleep

    - by user206217
    I'm running Lubunu 13.10 on an hp G62 - I'm new to Lubuntu having used ubuntu previously, but I've made the switch as my laptop is now getting toward the lower end of acceptability, and I'm delighted with how well it runs. Anyway, I'm having an issue that if I close the lid of the laptop it won't reconnect to the wi-fi when I open it again, and I'm not sure how to even force it to scan for a network - I have to restart it at the moment - and then it always connects perfectly. The router is a BT Business Hub 405. Any help much appreciated - thank you.

  • Java and .NET cost of use [on hold]

    - by 1110
    I work with .NET technology stack for about 4 years. I am learning and enjoy working with ASP MVC framework and I never did anything serious in other languages. This is not the question like what is better (I read all similar questions). What interest me is the cost of switching. For example: If you are about to start a start-up company today and you are in my situation not too much money, some good idea that you think others will use and have a knowledge of .NET. In my head I have a few questions that I can't answer and I know that somebody with experience can: 1) Java & .NET hosting. Suppose shared hosting is not good enough anymore, your site has grown and you need more resources. How much Java services is cheaper compared to .NET? 2) I didn't follow hype about ORACLE will kill java long time. Does oracle show interest in investing in java. I mean is is safe to bet on java as a technology when starting start-up (basically did oracle show some will to destroy java platform)? 3) I am not sure what I am asking here. When you use Java you can use JEEE stack or Java with third party stack (spring, hibernate, maven etc.). I saw a lot of project that work with second option if web application is not enterprise level but social networking site for example which stack is best pick? Summary of this question is is it safe to jump in to Java learn it and build product based on it. It's not too hard for me to learn it. But how much can I get from it.

  • My wireless connection isn't working well

    - by Maikel Braas
    So this is my problem, I intalled ubuntu 12.04 with the wubi.exe and everything works fine, but my internet connection. When I try to install a program or use firefox, it goes with 24kb/s with a little luck for 1-2 seconds and then my internet terminates and it starts up again after 3-5 mins. Then it goes with an other 24kb/s and this will repeat. The thing is my connection works perfectly with windows. The laptop its running on is a Acer ASPIRE V3-771G. I tryed using a different network adaptor but that didn't help either. Please, some one help me with this. friendly regards, Maikel

  • ASUS VX-6 Laptop Wireless not connecting

    - by user2152790
    Someone posted a script a couple days ago, here is my output.Pastebin I can see wifi SSIDs in network, but cannot connect to mine. The only time wifi worked on 13.10 was in the Live CD, but wifi stopped working as soon as install process started. Did below but made no difference. sudo apt-get install bcmwl-kernel-source sudo modprobe -rv brcmsmac sudo modprobe -v wl What I do next? I tried Software&Updates and it showed 1 proprietary driver in use. This sounds like a WPA/WPA2 issue? Wifi works when I tried Zorin OS 7.1, wifi always worked in windows 7.

  • Linux does not connect to wireless network under Hyper-V with Windows 8

    - by Graznarak
    I have a VM I am trying to run under Hyper-V on Windows 8 Pro. I am using an Asus PDE-N15 adapter on the host machine. When I run Windows 8 in the VM it connects to the network and everything works. When I use Linux (Ubuntu 13.04 32-bit, Ubuntu 13.04 64-bit, Fedora, CentOS) it will not connect to the network. When I run ifconfig I see the adapter show up as eth0 with the correct HWaddr. I see that TX bytes 0, and RX bytes == 0. Could anyone help me figure out how to get this to work?

    I get this weird error everytime I debug in eclipse. It just seemed to appear one day and I was wondering if anyone else was running int the same problem. It does not affect my app in anyway visibly and does not cause a crash but it is an annoyance while debugging. Here is the full error: // Compiled from DexFile.java (version 1.5 : 49.0, super bit) public final class dalvik.system.DexFile { // Method descriptor #8 (Ljava/io/File;)V // Stack: 3, Locals: 2 public DexFile(java.io.File file) throws java.io.IOException; 0 aload_0 [this] 1 invokespecial java.lang.Object() [1] 4 new java.lang.RuntimeException [2] 7 dup 8 ldc <String "Stub!"> [3] 10 invokespecial java.lang.RuntimeException(java.lang.String) [4] 13 athrow Line numbers: [pc: 0, line: 4] Local variable table: [pc: 0, pc: 14] local: this index: 0 type: dalvik.system.DexFile [pc: 0, pc: 14] local: file index: 1 type: java.io.File // Method descriptor #18 (Ljava/lang/String;)V // Stack: 3, Locals: 2 public DexFile(java.lang.String fileName) throws java.io.IOException; 0 aload_0 [this] 1 invokespecial java.lang.Object() [1] 4 new java.lang.RuntimeException [2] 7 dup 8 ldc <String "Stub!"> [3] 10 invokespecial java.lang.RuntimeException(java.lang.String) [4] 13 athrow Line numbers: [pc: 0, line: 5] Local variable table: [pc: 0, pc: 14] local: this index: 0 type: dalvik.system.DexFile [pc: 0, pc: 14] local: fileName index: 1 type: java.lang.String // Method descriptor #22 (Ljava/lang/String;Ljava/lang/String;I)Ldalvik/system/DexFile; // Stack: 3, Locals: 3 public static dalvik.system.DexFile loadDex(java.lang.String sourcePathName, java.lang.String outputPathName, int flags) throws java.io.IOException; 0 new java.lang.RuntimeException [2] 3 dup 4 ldc <String "Stub!"> [3] 6 invokespecial java.lang.RuntimeException(java.lang.String) [4] 9 athrow Line numbers: [pc: 0, line: 6] Local variable table: [pc: 0, pc: 10] local: sourcePathName index: 0 type: java.lang.String [pc: 0, pc: 10] local: outputPathName index: 1 type: java.lang.String [pc: 0, pc: 10] local: flags index: 2 type: int // Method descriptor #28 ()Ljava/lang/String; // Stack: 3, Locals: 1 public java.lang.String getName(); 0 new java.lang.RuntimeException [2] 3 dup 4 ldc <String "Stub!"> [3] 6 invokespecial java.lang.RuntimeException(java.lang.String) [4] 9 athrow Line numbers: [pc: 0, line: 7] Local variable table: [pc: 0, pc: 10] local: this index: 0 type: dalvik.system.DexFile // Method descriptor #30 ()V // Stack: 3, Locals: 1 public void close() throws java.io.IOException; 0 new java.lang.RuntimeException [2] 3 dup 4 ldc <String "Stub!"> [3] 6 invokespecial java.lang.RuntimeException(java.lang.String) [4] 9 athrow Line numbers: [pc: 0, line: 8] Local variable table: [pc: 0, pc: 10] local: this index: 0 type: dalvik.system.DexFile // Method descriptor #32 (Ljava/lang/String;Ljava/lang/ClassLoader;)Ljava/lang/Class; // Stack: 3, Locals: 3 public java.lang.Class loadClass(java.lang.String name, java.lang.ClassLoader loader); 0 new java.lang.RuntimeException [2] 3 dup 4 ldc <String "Stub!"> [3] 6 invokespecial java.lang.RuntimeException(java.lang.String) [4] 9 athrow Line numbers: [pc: 0, line: 9] Local variable table: [pc: 0, pc: 10] local: this index: 0 type: dalvik.system.DexFile [pc: 0, pc: 10] local: name index: 1 type: java.lang.String [pc: 0, pc: 10] local: loader index: 2 type: java.lang.ClassLoader // Method descriptor #37 ()Ljava/util/Enumeration; // Signature: ()Ljava/util/Enumeration<Ljava/lang/String;>; // Stack: 3, Locals: 1 public java.util.Enumeration entries(); 0 new java.lang.RuntimeException [2] 3 dup 4 ldc <String "Stub!"> [3] 6 invokespecial java.lang.RuntimeException(java.lang.String) [4] 9 athrow Line numbers: [pc: 0, line: 10] Local variable table: [pc: 0, pc: 10] local: this index: 0 type: dalvik.system.DexFile // Method descriptor #30 ()V // Stack: 3, Locals: 1 protected void finalize() throws java.io.IOException; 0 new java.lang.RuntimeException [2] 3 dup 4 ldc <String "Stub!"> [3] 6 invokespecial java.lang.RuntimeException(java.lang.String) [4] 9 athrow Line numbers: [pc: 0, line: 11] Local variable table: [pc: 0, pc: 10] local: this index: 0 type: dalvik.system.DexFile // Method descriptor #42 (Ljava/lang/String;)Z public static native boolean isDexOptNeeded(java.lang.String arg0) throws java.io.FileNotFoundException, java.io.IOException; } Thanks

    - by Tahir Akram
    Hi I am using Twitter4J API on GAE/J. I want to use the request token when user came to my page. (called back URL). And press refresh button. I write following code for that. But When user press refresh button. I got Authentication credentials error. Please see the stacktrance. It works fine when user first time used that token. HomeServlet.java code: HttpSession session = request.getSession(); twitter.setOAuthConsumer(FFConstants.CONSUMER_KEY, FFConstants.CONSUMER_SECRET); String token = (String) session.getAttribute("token"); String authorizedToken = (String)session.getAttribute("authorizedToken"); User user = null; if (!token.equals(authorizedToken)){ AccessToken accessToken = twitter.getOAuthAccessToken( token, (String) session .getAttribute("tokenSecret")); twitter.setOAuthAccessToken(accessToken); user = twitter.verifyCredentials(); session.setAttribute("authorizedToken", token); session.setAttribute("user", user); }else{ user = (User)session.getAttribute("user"); } TwitterUser twitterUser = new TwitterUser(); twitterUser.setFollowersCount(user.getFollowersCount()); twitterUser.setFriendsCount(user.getFriendsCount()); twitterUser.setFullName(user.getName()); twitterUser.setScreenName(user.getScreenName()); twitterUser.setLocation(user.getLocation()); Please suggest how I can do that. I have seen on many website. They retain the user with the same token. Even if user press browser refresh buttion again and again. Please help.
