  • WCF Service, Java JApplet client, transport error 405

    - by Juan Zamudio
    Hi all, I'm having a problem with a WCF Service and Java Client, I will try to give as much information as i can, thanks for your time. The Endpoint of the server is BasicHttpBinding, I tried hosting the server as a Windows Service and in IIS but nothing changed. The weird thing is that the Client works great if I use a simple class, in the moment I switch the class to an JApplet I get the problem mentioned. I'm using Eclipse as an IDE, I tried Axis and Metro to generate the stub with the same bad results. Here is an example of the Java class where everything is working public class TestSoaMetro { public String TestMethod(){ String result=null; IDigitalSignatureService aa = new DigitalSignatureService().getBasicHttpBindingEndpoint(); try { result= aa.getData("1", "id002962"); } catch (IDigitalSignatureServiceGetDataArgumentExceptionFaultFaultMessage e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (IDigitalSignatureServiceGetDataInvalidOperationExceptionFaultFaultMessage e) { // TODO Auto-generated catch block e.printStackTrace(); } return result; } } Here is the example of the JApplet where I get the error: public class TestSoaMetroApplet extends JApplet { public void init() { Container content = getContentPane(); content.setBackground(Color.white); content.setLayout(new FlowLayout()); String result= this.TestMethod(); JLabel label = new JLabel(result); content.add(label); } public String TestMethod(){ String result=null; IDigitalSignatureService aa = null; try { aa = new DigitalSignatureService().getBasicHttpBindingEndpoint(); result= aa.getData("1", "id002962"); } catch (IDigitalSignatureServiceGetDataArgumentExceptionFaultFaultMessage e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (IDigitalSignatureServiceGetDataInvalidOperationExceptionFaultFaultMessage e) { // TODO Auto-generated catch block e.printStackTrace(); } return result; } } In the moment the Applet loads I get the error, is the exact same call so I don't understand why I get the exception using the Applet. I Also tried to call this from a Silverlight client and I was getting a security exception, this is where I found out about clientaccesspolicy.xml and crossdomain.xml, I added clientaccesspolicy.xml to the service and the Silverlight Client works great, so I decided to try crossdomain.xml and nothing, the Applet still does not work. I will put the stack trace at the end, thanks all for your time.

  • Which Programming Language Should I Learn?

    - by Esteban Araya
    I've decided, for educational purposes, I want to learn a new language every 2 years or so. Which language should I learn first? Why? I'm proficient with C, C# and Java. Other than that, I really haven't done much with any other languages. Thanks! Edit: Thanks to all of those that recommended functional languages. Making the mental switch to a functional language seems hard. How did you overcome your instinct to keep doing things in a procedural manner?

  • To keep my own versioned app or not.

    - by Esteban Feldman
    Hi all. I need some opinions here. I'm working on a Django project using buildout to get the dependencies, etc... I use mercurial as DVCS. Now... I need to customize one of the dependencies, so I can do one of the following: (* The changes may not be useful for everyone else.) 1- Do a fork of the project in (github, bitbucket, etc...) maintain my version, and get the dependency with (mercurial or git) recipe. 2- Clone the project, put it in the PYTHONPATH, erase DVCS dirs and add it to my projects version. So every change will be private. Here I need to erase all the info from their DVCS or something. Any other you can think of. I'm missing something? I'm too off? Thanks!

  • Does mercurial-server support subrepo?

    - by Esteban Feldman
    I installed mercurial-server on one of my machines, cloned my project there, it has 3 subrepos, and when I try to clone it back to another location I get an error: remote: mercurial-server: Cannot create repo under existing repo abort: no suitable response from remote hg! So I'm starting to think that mercurial-server doesn't handle subrepo. Any clue?

  • Django: text fixture fails to load

    - by Esteban Feldman
    Hi all, Did a dumpdata of my project, then in my new test I added it to fixtures. from django.test import TestCase class TestGoal(TestCase): fixtures = ['test_data.json'] def test_goal(self): """ Tests that 1 + 1 always equals 2. """ self.failUnlessEqual(1 + 1, 2) When running the test I get: Problem installing fixture 'XXX/fixtures/test_data.json': DoesNotExist: XXX matching query does not exist. But manually doing loaddata works fine does not when the db is empty. I do a dropdb, createdb a simple syncdb the try loaddata and it fails, same error. Any clue? Python version 2.6.5, Django 1.1.1

  • When should I use a struct instead of a class?

    - by Esteban Araya
    MSDN says that you should use structs when you need lightweight objects. Are there any other scenarios when a struct is preferable over a class? Edit: Some people have forgotten that: 1. structs can have methods! 2. structs have no inheritance capabilites. Another Edit: I understand the technical differences, I just don't have a good feel for WHEN to use a struct.

  • Xenserver 5.6 SR_BACKEND_FAILURE_47 no such volume group, but it is there

    - by Juan Carlos
    I've looked everywhere (Google, here, a bunch of other sites), and while I have found people with similar problems, I couldn't find a single one with a solution to this. Last night our xenserver 5.6 box corrupted the /var/xapi/state.db, and I couldn't fix the xml, no matter what I did. After a good hour fiddling with the file, I figured it would be faster to just reinstall. The server had one 2tb hard drive running Xen and its VMs, and since Xen's install said it would erase the hard drive it was installed on, I plugged a new harddrive and installed Xen on it, without selecting any hard drives for storage. I Figured I could make it happen after install, using the partition on the old harddrive with all my VMs on it. After instalation finished and the system booted I did: #fdisk -l found the old partition at /dev/sda3 #ll /dev/disk/by-id found the partition at /dev/disk/by-id/scsi-3600188b04c02f100181ab3a48417e490-part3 #xe host-list uuid ( RO) : a019d93e-4d84-4a4b-91e3-23572b5bd8a4 name-label ( RW): xenserver-scribfourteen name-description ( RW): Default install of XenServer #pvscan PV /dev/sda3 VG VG_XenStorage-405a2ece-d10e-d6c5-ede2-e1ad2c29c68d lvm2 [1.81 TB / 204.85 GB free] Total: 1 [1.81 TB] / in use: 1 [1.81 TB] / in no VG: 0 [0 ] #vgscan Reading all physical volumes.

I cant lose those VMs (got backups, but from inside the guests, not the VMs themselves).

  • Active Directory intergration with linux users and zimbra

    - by Juan Diego
    I have the following questions about setting an active directory, that already has users and a domain, (i.e. internaldomain.edu) and real domain (i.e mydomain.edu.), and I have seeing many examples of the integration of AD with linux and usually they have a domain like intranet.mydomain.edu. Should I change "internaldomain.edu" to intranet.mydomain.edu or to mydomain.edu, or I can leave that internaldomain.edu like it is and create another domain. I am a littlebit confused with these, I know one is the windows domain but I dont know if that affects my email users.

  • Openldap, groups, admin groups, etc

    - by Juan Diego
    We have a samba server as PDC with OpenLDAP. So far everything is working, even windows 7 can log on to the Domain. Here is the tricky part. We have many departments, each department has it's own IT guys, and these IT guy should be able to create users in their department and change any info of the users in their department. My Idea was to create 2 groups for each department, For example: Department1 and Admins Department1. Admins Deparment1 has "write" priviledges for members of group Department dn: ou=People,dc=mydomain,dc=com,dc=ec objectClass: top objectClass: organizationalUnit ou: People dn: cn=Admins,ou=Group,dc=mydomain,dc=com,dc=ec objectClass: groupOfNames objectClass: top cn: Admins dn: cn=Admins Department1,cn=Admins,ou=Group,dc=mydomain,dc=com,dc=ec objectClass: groupOfNames objectClass: top cn: Admins Department1 member: uid=jdc,ou=People,dc=mydomain,dc=com,dc=ec structuralObjectClass: groupOfNames I dont know if you should make Department1 as part of Domain Users dn: cn=Deparment1,cn=Domain Users,ou=Group,dc=mydomain,dc=com,dc=ec objectClass: groupOfNames objectClass: top cn: Deparment1 member: uid=user1,ou=People,dc=mydomain,dc=com,dc=ec Or just create the deparments like this. dn: cn=Deparment1,ou=Group,dc=mydomain,dc=com,dc=ec objectClass: groupOfNames objectClass: top cn: Deparment1 member: uid=user1,ou=People,dc=mydomain,dc=com,dc=ec I seems that when you use smbldap tools bydefault the users are part of Domain Users even if you dont have them as part of Domain Users in the memberUid attribute, when I use finger they showup as part of the Domain Users group. I dont want the Departments Admins to be Domain Admins because they have power over all the users, unless I am mistaken. I also have trouble with the ACLs. I was trying to create an acl for members of this Admins group, I was trying with this search, but didnt work ldapsearch -x "(&(objectClass=organizationalPerson)(member=cn=Admins Department1,ou=Group,dc=mydomain,dc=com,dc=ec))" I am open to suggestions.

  • Mac Pro updated to OS X 10.6 (Snow Leopard) doesn't recognize second SuperDrive

    - by Juan
    This Mac Pro has dual SuperDrives both upper/lower drivebays, which could be independently ejected via the menubar under 10.5. After upgrading to 10.6, the upper drive no longer responds to the menu command. The eject button has to be hand-pressed with a paperclip to open (but a loaded disc can still be ejected via dragging to the trash). Sounds like a simple setting somewhere, except I can't find it to re-enable the second drive.

  • Enable dtrace without sudo on Mac OS X?

    - by Juan
    How do I enable users to use dtrace on Mac OS X. I am trying to do the equivalent of strace on Linux, and I don't like running applications with elevated privileges. UPDATE Ok, the best I can tell. The only way to keep a nefarious application from ruining the system by debugging it is to. Attach to the process in a separate console Use sudo twice So that: sudo dtruss sudo -u myusername potentially_harmful_app I verified this with this short program: #include <iostream> #include <unistd.h> int main() { std::cout << "effective euid " << geteuid() << "\n"; } See this discussion for more info: http://discussions.apple.com/message.jspa?messageID=6430877

  • after upgrade to outlook 2013 Contacts have the default picture in reading pane

    - by Juan Zamudio
    I'm using Windows 8 on a domain (using a domain account not a Microsoft account) connecting to Exchange, all my Contacts were outlook contacts with pictures and other data, I could see the picture of the contact in the reading pane and people pane while using Outlook 2010. After the upgrade to Outlook 2013 I can see my outlook contacts but it appears that they are unavailable in the reading pane because all i can see is the default picture (the default picture picture is also visible in the notifications). If I put the mouse over the name of the people while in the reading pane all I can see is the card with the default info (the only data is that the contact is available in the next 8 hours), if i compose a new message and hover the name of the contact i can see the card with all the data (picture, company, etc.). Is this the default behavior in Outlook 2013 if you are in a domain and not connected to any service or there is a way to show the picture of my contacts in every part of outlook?

  • MPEG2-TS streaming: UDP or RTP?

    - by Juan Jose Polanco Arias
    Hello I'm working on an IPTV streaming server in Linux (Ubuntu Server 12.04 LTS) that has a DVB-S/S2 card to obtain satellite channels. Then with MuMuDVB I map all channels in the transponder to a multicast group, for multicast transmission. Now for the MuMuDVB software I can either use UDP for transmission or I can add the RTP header. I was wondering what would be the most convenient for MPEG2-TS because I've heard that RTP is used primarily for MPEG4, but It's also said that RTP can be used for MPEG2-TS. Thanks for your help.

  • Mouse and touchpad move at different speeds

    - by Juan Manuel
    I have a compaq 610 running windows 7, and I use a USB mouse on it. The pointer speed is different for the mouse and the touchpad, so when I go to a meeting and take the notebook but not the mouse, the pointer moves too slow using the touchpad and I have to manually adjust it (of course when I return, I have to slow it down because the mouse would move the pointer too fast). Is there any way to fix this, or to have this setting separate for both devices?
