  • How do I turn a Wi-Fi "hotspot" into a local wired network?

    - by Max Schmeling
    Here's the situation: In a remote "office" I have a computer with no network connection, that I need to network with when I'm at this remote office. There is a wireless network where this computer is, but no wireless adapter in the computer. I have a laptop running Windows 7 that can connect to the wireless, and the computer is running Windows Vista. What is the best way to get them both connected? I know I can buy a USB wireless adapter or something for the computer, but is there an easy way to do it with what I've got?

  • How to redirect / route VPN traffic to back standing local network?

    - by Milkywayfarer
    There are two computers one "HOME" with Ubuntu 10.10 installed, and another "WORK" with WinXP installed. WORK PC is behind draconian firewall. However, let's imagine, that there is VPN connection installed between this 2 work stations, for example, with teamviewer, hamachi, openvpn, or by some other mean (by the way, what is the best mean for such purposes?). One is interested in working with WORK's LAN resources from his HOME computer via VPN. So my question is about configuration required to be done on WinXP machine (or, maybe on both machines), to make such interaction possible? I'm guessing that some routing stuff should be performed somewhere. But I don't know what exactly and how to do?

  • Nginx works on my linux machine but is not accessible from other computers in my local network

    - by crooveck
    In my LAN network I have a server with Scientific Linux (RedHat or Fedora based distro), I've done yum install nginx but the welcome page is not accessible from other computers in my network. When I do telnet open localhost 80 and then GET / HTTP/1.0 I get some html code from nginx, so it's running for sure. But when I want to connect remotly, doing telnet open 192.168.3.130 80 I get: Trying 192.168.3.130... telnet: Unable to connect to remote host: No route to host So I assume that there is something wrong with my network settings, maybe iptables or something else? Next step, I turned off iptables: service iptables stop and it helped, now I can connect remotely using telnet. So I think, I need to fix my iptables rules. I did some googling and found this rule -A INPUT -m state --state NEW -m tcp -p tcp --dport 80 -j ACCEPT but it still didn't allow me to connect remotely when iptables is up. Can someone please help me setting a proper iptables configuration?

  • How to access files on another local Windows 7 computer without using any native Windows features?

    - by user1356682
    I do not want to use any native Windows features, services, nor anything do to this. It needs to be a standalone program, with ZERO Windows dependencies. Just like TeamViewer does not use any native Windows features, so I want to be able to access files and folders in a standalone program. No remote desktop No VNC type programs No Windows File Sharing No Shared Folders in Windows No internet connection required It needs ability to view, edit, transfer files at normal network rates.

  • ImageMagick on Mac OSX Snow Leopard. Is there any way to get it to work?

    - by ?????
    It seems that I have more trouble getting standard Unix things to run on Snow Leopard than any other platform--including Windows cygwin For the past couple of days, I've been trying to get ImageMagick to run on Snow Leopard. The most obvious way, Mac Ports, fails: tppllc-Mac-Pro:ImageMagick-sl swirsky$ sudo port install imagemagick ---> Computing dependencies for p5-locale-gettext ---> Configuring p5-locale-gettext Error: Target org.macports.configure returned: configure failure: shell command " cd "/opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_ports_perl_p5-locale-gettext/work/gettext-1.05" && /opt/local/bin/perl Makefile.PL INSTALLDIRS=vendor " returned error 2 Command output: checking for gettext... no checking for gettext in -I/opt/local/include -arch i386 -L/opt/local/lib -lintl...gettext function not found.

So now I'm two steps away from ImageMagick, trying to get a newer libiconv on my machine. I downloaded the latest libiconv, compiled and built it. I put the resulting library in /opt/local/lib, and I still get the same error message: tppllc-Mac-Pro:.libs swirsky$ sudo mv libiconv.2.dylib /opt/local/lib/libiconv.2.dylib tppllc-Mac-Pro:.libs swirsky$ convert dyld: Library not loaded: /opt/local/lib/libiconv.2.dylib Referenced from: /opt/local/lib/libfontconfig.1.dylib Reason: Incompatible library version: libfontconfig.1.dylib requires version 8.0.0 or later, but libiconv.2.dylib provides version 7.0.0 Trace/BPT trap So here's my question: Is it possible to get ImageMagick to run on OSX Snow Leopard? Are there any binary distributions that have static libraries baked in so I don't have to worry about these issue/

  • How the JOptionPane works

    - by DevAno1
    How can I control what happens with window after clicking JOPtionPane buttons ? I'm trying to implement simple file chooser. In my frame I have 3 buttons (OK, Cancel, Browse). Browse button opens file search window, and after picking files should return to main frame. Clicking OK will open a frame with the content of the file. Now porblem looks this way. With the code below, I can choose file but directly after that a new frame is created, and my frame with buttons dissapears : import java.io.File; import java.io.BufferedReader; import java.io.FileReader; import java.io.IOException; import java.awt.*; import javax.swing.*; import java.io.*; public class Main { public static void main(String args[]) { javax.swing.SwingUtilities.invokeLater(new Runnable() { public void run() { show("Window"); } }); } public static void show(String frame_name){ JFrame frame = new JFrame(frame_name); frame.setPreferredSize(new Dimension(450, 300)); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); JPanel top = new JPanel(); top.setLayout(new BoxLayout(top, BoxLayout.Y_AXIS)); JFileChooser fc = new JFileChooser(new File(".")); JPanel creator = new JPanel(); creator.setLayout(new BoxLayout(creator, BoxLayout.Y_AXIS)); creator.add(top); String[] buttons = {"OK", "Cancel", "Browse"}; int rc = JOptionPane.showOptionDialog( null, creator, frame_name, JOptionPane.DEFAULT_OPTION, JOptionPane.PLAIN_MESSAGE, null, buttons, buttons[0] ); String approveButt = ""; switch(rc){ case 0: break; case 1: break; case 2: approveButt = buttons[rc]; int retVal = fc.showDialog(null, approveButt); if (retVal == JFileChooser.APPROVE_OPTION) System.out.println(approveButt + " " + fc.getSelectedFile()); break; } frame.pack(); frame.setVisible(true); } } With the second code I can return to my menu, but in no way I am able to pop this new frame, which appeared with first code. How to control this ? What am I missing ? public class Main { public static void main(String args[]) { javax.swing.SwingUtilities.invokeLater(new Runnable() { public void run() { show("Window"); } }); } public static void show(String frame_name){ JFrame frame = new JFrame(frame_name); frame.setPreferredSize(new Dimension(450, 300)); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); JPanel top = new JPanel(); top.setLayout(new BoxLayout(top, BoxLayout.Y_AXIS)); JFileChooser fc = new JFileChooser(new File(".")); JPanel creator = new JPanel(); creator.setLayout(new BoxLayout(creator, BoxLayout.Y_AXIS)); creator.add(top); String[] buttons = {"OK", "Cancel", "Browse"}; String approveButt = ""; Plane m = null; int rc = -1; while (rc != 0) { rc = JOptionPane.showOptionDialog( null, creator, frame_name, JOptionPane.DEFAULT_OPTION, JOptionPane.PLAIN_MESSAGE, null, buttons, buttons[0] ); switch (rc) { case 0: m = new Plane(); case 1: System.exit(0); case 2: approveButt = buttons[rc]; int retVal = fc.showDialog(null, approveButt); if (retVal == JFileChooser.APPROVE_OPTION) System.out.println(approveButt + " " + fc.getSelectedFile()); break; default: break; } } addComponents(frame.getContentPane(), m); frame.pack(); frame.setVisible(true); } private static void addComponents(Container c, Plane e) { c.setLayout(new BoxLayout(c, BoxLayout.Y_AXIS)); c.add(e); } } class Plane extends JPanel { public Plane(){ } @Override public void paint(Graphics g){ g.setColor(Color.BLUE); g.fillRect(0, 0, 400, 250); } }

  • Can't run init script on boot after another init script

    - by Colin McQueen
    I have three init scripts and the Broker init script runs fine, but when I try to run the Consumer init script and then the Data Collector init script, the only process that is running is the Broker. I added the symbolic links to the run levels using update-rc.d for each script and I also changed the number prefixes in the symbolic links to try and run the scripts in the proper order but that did not work. I am able to run the scripts from the terminal and they work fine but they need to all be started on boot. Any ideas as to why my other scripts are not running? Also inside my Consumer and Data Collector I am running: su user1 -c 'java -jar foo.jar' to start the services. Also the Consumer Java class sits and waits for a message from the queue, so the Java code does not stop until I specify the stop argument for the init script. The Broker has to start first, then the Consumer, then the Data Collector. Adding the symbolic links for the runlevels: sudo update-rc.d Broker defaults 10 90 sudo update-rc.d Consumer defaults 15 85 sudo update-rc.d DataCollector defaults 20 80

  • Issues printing through ssh tunnel and port forwarding

    - by simogasp
    I'm having some problems trying to print through a ssh tunnel. I'd like to print from my laptop to a network printer (Toshiba es453, for what matters) which is in a local network. I can reach the local network using a gateway. So far I did the following: ssh -N -L19100:<Printer_IP>:9100 <username>@<ssh_gateway> Basically i just mapped the port 19100 of my laptop directly to the input port of the printer, passing through the gateway. So far, so good. Then, i tried to install on my laptop a new printer with the GUI config tool of ubuntu, so that the new printer is on localhost at port 19100 (as APP Socket/HP Jet Direct) , then I provided the proper driver of the printer. In theory, once the tunnel is open I should be able to print from any program just selecting this printer. Of course, it does not work. :-) The document hangs in the queue with status Processing while in the shell where I set up the tunnel I get these errors on failing opening channels debug1: Local forwarding listening on ::1 port 19100. debug1: channel 0: new [port listener] debug1: Local forwarding listening on 127.0.0.1 port 19100. debug1: channel 1: new [port listener] debug1: Requesting [email protected] debug1: Entering interactive session. debug1: Connection to port 19100 forwarding to 195.220.21.227 port 9100 requested. debug1: channel 2: new [direct-tcpip] debug1: Connection to port 19100 forwarding to 195.220.21.227 port 9100 requested. debug1: channel 3: new [direct-tcpip] channel 2: open failed: connect failed: Connection timed out debug1: channel 2: free: direct-tcpip: listening port 19100 for 195.220.21.227 port 9100, connect from ::1 port 44434, nchannels 4 debug1: Connection to port 19100 forwarding to 195.220.21.227 port 9100 requested. debug1: channel 2: new [direct-tcpip] channel 3: open failed: connect failed: Connection timed out debug1: channel 3: free: direct-tcpip: listening port 19100 for 195.220.21.227 port 9100, connect from ::1 port 44443, nchannels 4 channel 2: open failed: connect failed: Connection timed out debug1: channel 2: free: direct-tcpip: listening port 19100 for 195.220.21.227 port 9100, connect from ::1 port 44493, nchannels 3 debug1: Connection to port 19100 forwarding to 195.220.21.227 port 9100 requested. debug1: channel 2: new [direct-tcpip] As a further debugging test I tried the following. From a machine inside the local network I did a telnet <IP_printer> 9100, got access, wrote some random thing, closed the connection and correctly I got a print of what I had written. So the port and the ip of the printer should be correct. I tried the same from my laptop with the tunnel opened, the telnet succeeded but, again, the printer didn't print anything, getting the usual channel x: open failed: errors. I'm not a great expert on the matter, I just thought that in theory it was possible to do something like that, but maybe there is something that I didn't consider or I did wrong. Any clue? Thanks! Simone [update] As further debugging test, I tried to replicate the procedure from a machine in the local network. From that machine, I did ssh -N -L19100:<IP_printer>:9100 <username>@<ssh_gateway> (note that now the machine, the gateway and the printer are in the same local network) then I tried again the telnet test with telnet localhost 19100, I got access and everything, but I didn't get the print but the usual error channel 2: open failed: connect failed: Connection timed out Maybe I am missing some other connection to be forwarded or maybe this is not allowed by the administrators. Of course, if I connect via ssh tunneling to the local machine from my laptop through the gateway, I can successfully print using the lpr command (from the local machine). But this is what I would like to avoid (yes, I'm lazy...:-), I would like to have a more 'elegant' and transparent way to do that.

  • dpkg reporting as installed, uninstalled kernels

    - by Tony Martin
    I have run the following command to remove old kernels: dpkg -l 'linux-*' | sed '/^ii/!d;/'"$(uname -r | sed "s/\(.*\)-\([^0-9]\+\)/\1/")"'/d;s/^[^ ]* [^ ]* \([^ ]*\).*/\1/;/[0-9]/!d' | xargs sudo apt-get -y purge and only the current kernel is now installed, which I have confirmed in synaptic and by checking my boot partition. However, when I run: dpkg --list | grep linux-image I get the following response: rc linux-image-3.13.0-30-generic 3.13.0-30.55 amd64 Linux kernel image for version 3.13.0 on 64 bit x86 SMP rc linux-image-3.13.0-32-generic 3.13.0-32.57 amd64 Linux kernel image for version 3.13.0 on 64 bit x86 SMP ii linux-image-3.13.0-34-generic 3.13.0-34.60 amd64 Linux kernel image for version 3.13.0 on 64 bit x86 SMP rc linux-image-extra-3.13.0-30-generic 3.13.0-30.55 amd64 Linux kernel extra modules for version 3.13.0 on 64 bit x86 SMP rc linux-image-extra-3.13.0-32-generic 3.13.0-32.57 amd64 Linux kernel extra modules for version 3.13.0 on 64 bit x86 SMP ii linux-image-extra-3.13.0-34-generic 3.13.0-34.60 amd64 Linux kernel extra modules for version 3.13.0 on 64 bit x86 SMP ii linux-image-generic 3.13.0.34.40 amd64 Generic Linux kernel image Probably not a problem, but just wondering why versions -30 and -32 are reported as present.

The previous posts were: JMS Step 1 - How to Create a Simple JMS Queue in Weblogic Server 11g JMS Step 2 - Using the QueueSend.java Sample Program to Send a Message to a JMS Queue JMS Step 3 - Using the QueueReceive.java Sample Program to Read a Message from a JMS Queue JMS Step 4 - How to Create an 11g BPEL Process Which Writes a Message Based on an XML Schema to a JMS Queue JMS Step 5 - How to Create an 11g BPEL Process Which Reads a Message Based on an XML Schema from a JMS Queue This example leads you through the creation of an Oracle database Advanced Queue and the related WebLogic server objects in order to use AQ JMS in connection with a SOA composite. If you have not already done so, I recommend you look at the previous posts in this series, as they include steps which this example builds upon. The following examples will demonstrate how to write and read from the queue from a SOA process. 1. Recap and Prerequisites In the previous examples, we created a JMS Queue, a Connection Factory and a Connection Pool in the WebLogic Server Console. Then we wrote and deployed BPEL composites, which enqueued and dequeued a simple XML payload. AQ JMS allows you to interoperate with database Advanced Queueing via JMS in WebLogic server and therefore take advantage of database features, while maintaining compliance with the JMS architecture. AQ JMS uses the WebLogic JMS Foreign Server framework. A full description of this functionality can be found in the following Oracle documentation Oracle® Fusion Middleware Configuring and Managing JMS for Oracle WebLogic Server 11g Release 1 (10.3.6) Part Number E13738-06 7. Interoperating with Oracle AQ JMS http://docs.oracle.com/cd/E23943_01/web.1111/e13738/aq_jms.htm#CJACBCEJ For easier reference, this sample will use the same names for the objects as in the above document, except for the name of the database user, as it is possible that this user already exists in your database. We will create the following objects Database Objects Name Type AQJMSUSER Database User MyQueueTable Advanced Queue (AQ) Table UserQueue Advanced Queue WebLogic Server Objects Object Name Type JNDI Name aqjmsuserDataSource Data Source jdbc/aqjmsuserDataSource AqJmsModule JMS System Module AqJmsForeignServer JMS Foreign Server AqJmsForeignServerConnectionFactory JMS Foreign Server Connection Factory AqJmsForeignServerConnectionFactory AqJmsForeignDestination AQ JMS Foreign Destination queue/USERQUEUE eis/aqjms/UserQueue Connection Pool eis/aqjms/UserQueue 2. Create a Database User and Advanced Queue The following steps can be executed in the database client of your choice, e.g. JDeveloper or SQL Developer. The examples below use SQL*Plus. Log in to the database as a DBA user, for example SYSTEM or SYS. Create the AQJMSUSER user and grant privileges to enable the user to create AQ objects. Create Database User and Grant AQ Privileges sqlplus system/password as SYSDBA GRANT connect, resource TO aqjmsuser IDENTIFIED BY aqjmsuser; GRANT aq_user_role TO aqjmsuser; GRANT execute ON sys.dbms_aqadm TO aqjmsuser; GRANT execute ON sys.dbms_aq TO aqjmsuser; GRANT execute ON sys.dbms_aqin TO aqjmsuser; GRANT execute ON sys.dbms_aqjms TO aqjmsuser; Create the Queue Table and Advanced Queue and Start the AQ The following commands are executed as the aqjmsuser database user. Create the Queue Table connect aqjmsuser/aqjmsuser; BEGIN dbms_aqadm.create_queue_table ( queue_table = 'myQueueTable', queue_payload_type = 'sys.aq$_jms_text_message', multiple_consumers = false ); END; / Create the AQ BEGIN dbms_aqadm.create_queue ( queue_name = 'userQueue', queue_table = 'myQueueTable' ); END; / Start the AQ BEGIN dbms_aqadm.start_queue ( queue_name = 'userQueue'); END; / The above commands can be executed in a single PL/SQL block, but are shown as separate blocks in this example for ease of reference. You can verify the queue by executing the SQL command SELECT object_name, object_type FROM user_objects; which should display the following objects: OBJECT_NAME OBJECT_TYPE ------------------------------ ------------------- SYS_C0056513 INDEX SYS_LOB0000170822C00041$$ LOB SYS_LOB0000170822C00040$$ LOB SYS_LOB0000170822C00037$$ LOB AQ$_MYQUEUETABLE_T INDEX AQ$_MYQUEUETABLE_I INDEX AQ$_MYQUEUETABLE_E QUEUE AQ$_MYQUEUETABLE_F VIEW AQ$MYQUEUETABLE VIEW MYQUEUETABLE TABLE USERQUEUE QUEUE Similarly, you can view the objects in JDeveloper via a Database Connection to the AQJMSUSER. 3. Configure WebLogic Server and Add JMS Objects All these steps are executed from the WebLogic Server Administration Console. Log in as the webLogic user. Configure a WebLogic Data Source The data source is required for the database connection to the AQ created above. Navigate to domain > Services > Data Sources and press New then Generic Data Source. Use the values:Name: aqjmsuserDataSource JNDI Name: jdbc/aqjmsuserDataSource Database type: Oracle Database Driver: *Oracle’ Driver (Thin XA) for Instance connections; Versions:9.0.1 and later Connection Properties: Enter the connection information to the database containing the AQ created above and enter aqjmsuser for the User Name and Password. Press Test Configuration to verify the connection details and press Next. Target the data source to the soa server. The data source will be displayed in the list. It is a good idea to test the data source at this stage. Click on aqjmsuserDataSource, select Monitoring > Testing > soa_server1 and press Test Data Source. The result is displayed at the top of the page. Configure a JMS System Module The JMS system module is required to host the JMS foreign server for AQ resources. Navigate to Services > Messaging > JMS Modules and select New. Use the values: Name: AqJmsModule (Leave Descriptor File Name and Location in Domain empty.) Target: soa_server1 Click Finish. The other resources will be created in separate steps. The module will be displayed in the list.   Configure a JMS Foreign Server A foreign server is required in order to reference a 3rd-party JMS provider, in this case the database AQ, within a local WebLogic server JNDI tree. Navigate to Services > Messaging > JMS Modules and select (click on) AqJmsModule to configure it. Under Summary of Resources, select New then Foreign Server. Name: AqJmsForeignServer Targets: The foreign server is targeted automatically to soa_server1, based on the JMS module’s target. Press Finish to create the foreign server. The foreign server resource will be listed in the Summary of Resources for the AqJmsModule, but needs additional configuration steps. Click on AqJmsForeignServer and select Configuration > General to complete the configuration: JNDI Initial Context Factory: oracle.jms.AQjmsInitialContextFactory JNDI Connection URL: <empty> JNDI Properties Credential:<empty> Confirm JNDI Properties Credential: <empty> JNDI Properties: datasource=jdbc/aqjmsuserDataSource This is an important property. It is the JNDI name of the data source created above, which points to the AQ schema in the database and must be entered as a name=value pair, as in this example, e.g. datasource=jdbc/aqjmsuserDataSource, including the “datasource=” property name. Default Targeting Enabled: Leave this value checked. Press Save to save the configuration. At this point it is a good idea to verify that the data source was written correctly to the config file. In a terminal window, navigate to $MIDDLEWARE_HOME/user_projects/domains/soa_domain/config/jms  and open the file aqjmsmodule-jms.xml . The foreign server configuration should contain the datasource name-value pair, as follows:   <foreign-server name="AqJmsForeignServer">         <default-targeting-enabled>true</default-targeting-enabled>         <initial-context-factory>oracle.jms.AQjmsInitialContextFactory</initial-context-factory>         <jndi-property>           <key> datasource </key>           <value> jdbc/aqjmsuserDataSource </value>         </jndi-property>   </foreign-server> </weblogic-jms> Configure a JMS Foreign Server Connection Factory When creating the foreign server connection factory, you enter local and remote JNDI names. The name of the connection factory itself and the local JNDI name are arbitrary, but the remote JNDI name must match a specific format, depending on the type of queue or topic to be accessed in the database. This is very important and if the incorrect value is used, the connection to the queue will not be established and the error messages you get will not immediately reflect the cause of the error. The formats required (Remote JNDI names for AQ JMS Connection Factories) are described in the section Configure AQ Destinations  of the Oracle® Fusion Middleware Configuring and Managing JMS for Oracle WebLogic Server document mentioned earlier. In this example, the remote JNDI name used is   XAQueueConnectionFactory  because it matches the AQ and data source created earlier, i.e. thin with AQ. Navigate to JMS Modules > AqJmsModule > AqJmsForeignServer > Connection Factories then New.Name: AqJmsForeignServerConnectionFactory Local JNDI Name: AqJmsForeignServerConnectionFactory Note: this local JNDI name is the JNDI name which your client application, e.g. a later BPEL process, will use to access this connection factory. Remote JNDI Name: XAQueueConnectionFactory Press OK to save the configuration. Configure an AQ JMS Foreign Server Destination A foreign server destination maps the JNDI name on the foreign JNDI provider to the respective local JNDI name, allowing the foreign JNDI name to be accessed via the local server. As with the foreign server connection factory, the local JNDI name is arbitrary (but must be unique), but the remote JNDI name must conform to a specific format defined in the section Configure AQ Destinations  of the Oracle® Fusion Middleware Configuring and Managing JMS for Oracle WebLogic Server document mentioned earlier. In our example, the remote JNDI name is Queues/USERQUEUE , because it references a queue (as opposed to a topic) with the name USERQUEUE. We will name the local JNDI name queue/USERQUEUE, which is a little confusing (note the missing “s” in “queue), but conforms better to the JNDI nomenclature in our SOA server and also allows us to differentiate between the local and remote names for demonstration purposes. Navigate to JMS Modules > AqJmsModule > AqJmsForeignServer > Destinations and select New.Name: AqJmsForeignDestination Local JNDI Name: queue/USERQUEUE Remote JNDI Name:Queues/USERQUEUE After saving the foreign destination configuration, this completes the JMS part of the configuration. We still need to configure the JMS adapter in order to be able to access the queue from a BPEL processt. 4. Create a JMS Adapter Connection Pool in Weblogic Server Create the Connection Pool Access to the AQ JMS queue from a BPEL or other SOA process in our example is done via a JMS adapter. To enable this, the JmsAdapter in WebLogic server needs to be configured to have a connection pool which points to the local connection factory JNDI name which was created earlier. Navigate to Deployments > Next and select (click on) the JmsAdapter. Select Configuration > Outbound Connection Pools and New. Check the radio button for oracle.tip.adapter.jms.IJmsConnectionFactory and press Next. JNDI Name: eis/aqjms/UserQueue Press Finish Expand oracle.tip.adapter.jms.IJmsConnectionFactory and click on eis/aqjms/UserQueue to configure it. The ConnectionFactoryLocation must point to the foreign server’s local connection factory name created earlier. In our example, this is AqJmsForeignServerConnectionFactory . As a reminder, this connection factory is located under JMS Modules > AqJmsModule > AqJmsForeignServer > Connection Factories and the value needed here is under Local JNDI Name. Enter AqJmsForeignServerConnectionFactory  into the Property Value field for ConnectionFactoryLocation. You must then press Return/Enter then Save for the value to be accepted. If your WebLogic server is running in Development mode, you should see the message that the changes have been activated and the deployment plan successfully updated. If not, then you will manually need to activate the changes in the WebLogic server console.Although the changes have been activated, the JmsAdapter needs to be redeployed in order for the changes to become effective. This should be confirmed by the message Remember to update your deployment to reflect the new plan when you are finished with your changes. Redeploy the JmsAdapter Navigate back to the Deployments screen, either by selecting it in the left-hand navigation tree or by selecting the “Summary of Deployments” link in the breadcrumbs list at the top of the screen. Then select the checkbox next to JmsAdapter and press the Update button. On the Update Application Assistant page, select “Redeploy this application using the following deployment files” and press Finish. After a few seconds you should get the message that the selected deployments were updated. The JMS adapter configuration is complete and it can now be used to access the AQ JMS queue. You can verify that the JNDI name was created correctly, by navigating to Environment > Servers > soa_server1 and View JNDI Tree. Then scroll down in the JNDI Tree Structure to eis and select aqjms. This concludes the sample. In the following post, I will show you how to create a BPEL process which sends a message to this advanced queue via JMS.

  • jqGrid > datatype : "local" > get and save (at once) all edited cells of a column ?

    - by Qualliarys
    Hi, i have a grid with a datatype = "local". The data are an array as follows : var mydata = [{id:1,valeur:"a_value",designation:"a_designation"}, {id:2,...}, ...]; The second column (named valeur) is the only editable column of the grid (editable:true set in colModel) In the pager of the grid, i have 2 buttons. One to edit all cells (at once) of the column named valeur: $("#mygrid").jqGrid('navButtonAdd','#pager',{caption:"Edit values", onClickButton:function(){ var ids = $('#mygrid').jqGrid('getDataIDs'); for(var i=0;i<ids.length+1;i++){ $('#mygrid').jqGrid('editRow',ids[i],true);} }}); and another one to save (at once) all the changes of the edited cells: $("#mygrid").jqGrid('navButtonAdd','#pager',{caption:"Save changes", onClickButton:function(){var ids = $('#mygrid').jqGrid('getDataIDs'); for(var i=0;i<ids.length+1;i++){ ... ??? ... }}}); when i use : var rd = $("#mygrid").jqGrid('getRowData',ids[i]); alert("valeur="+rd.valeur); for each display i get something like that: valeur=< input class="editable" role="textbox" name="valeur" id="1_valeur" style="width: 98%;" type="text" ... So, when cells are in edition mode, all rd.valeur are an input text tag ! when they are not, i get the initials values of the cells ! How to get and save all changes of this column (all cells in edition mode)?

  • How to create static method that evaluates local static variable once?

    - by Viet
    I have a class with static method which has a local static variable. I want that variable to be computed/evaluated once (the 1st time I call the function) and for any subsequent invocation, it is not evaluated anymore. How to do that? Here's my class: template< typename T1 = int, unsigned N1 = 1, typename T2 = int, unsigned N2 = 0, typename T3 = int, unsigned N3 = 0, typename T4 = int, unsigned N4 = 0, typename T5 = int, unsigned N5 = 0, typename T6 = int, unsigned N6 = 0, typename T7 = int, unsigned N7 = 0, typename T8 = int, unsigned N8 = 0, typename T9 = int, unsigned N9 = 0, typename T10 = int, unsigned N10 = 0, typename T11 = int, unsigned N11 = 0, typename T12 = int, unsigned N12 = 0, typename T13 = int, unsigned N13 = 0, typename T14 = int, unsigned N14 = 0, typename T15 = int, unsigned N15 = 0, typename T16 = int, unsigned N16 = 0> struct GroupAlloc { static const uint32_t sizeClass; static uint32_t getSize() { static uint32_t totalSize = 0; totalSize += sizeof(T1)*N1; totalSize += sizeof(T2)*N2; totalSize += sizeof(T3)*N3; totalSize += sizeof(T4)*N4; totalSize += sizeof(T5)*N5; totalSize += sizeof(T6)*N6; totalSize += sizeof(T7)*N7; totalSize += sizeof(T8)*N8; totalSize += sizeof(T9)*N9; totalSize += sizeof(T10)*N10; totalSize += sizeof(T11)*N11; totalSize += sizeof(T12)*N12; totalSize += sizeof(T13)*N13; totalSize += sizeof(T14)*N14; totalSize += sizeof(T15)*N15; totalSize += sizeof(T16)*N16; totalSize = 8*((totalSize + 7)/8); return totalSize; } };

  • How can I run a local Windows Application and have the output be piped into the Browser.

    - by Trey Sherrill
    I have Windows Application (.EXE file is written in C and built with MS-Visual Studio), that outputs ASCII text to stdout. I’m looking to enhance the ASCII text to include limited HTML with a few links. I’d like to invoke this application (.EXE File) and take the output of that application and pipe it into a Browser. This is not a one time thing, each new web page would be another run of the Local Application! The HTML/java-script application below has worked for me to execute the application, but the output has gone into a DOS Box windows and not to pipe it into the Browser. I’d like to update this HTML Application to enable the Browser to capture that text (that is enhanced with HTML) and display it with the browser. <body> <script> function go() { w = new ActiveXObject("WScript.Shell"); w.run('C:/DL/Browser/mk_html.exe'); return true; } </script> <form> Run My Application (Window with explorer only) <input type="button" value="Go" onClick="return go()"> </FORM> </body>

  • Can I recover lost commits in a SVN repository using a local tracking git-svn branch?

    - by Ian Stevens
    A SVN repo I use git-svn to track was recently corrupted and a backup was recovered. However, a week's worth of commits were lost in the recovery. Is it possible to recover those lost commits using git-svn dcommit on my local git repo? Is it sufficient to run git-svn dcommit with the SHA1 of the last recovered commit in SVN? eg. > svn info http://tracked-svn/trunk | sed -n "s/Revision: //p" 252 > git log --grep="git-svn-id:.*@252" --format=oneline | cut -f1 -d" " 55bb5c9cbb5fe11a90ec2e9e1e0c7c502908cf9a > git svn dcommit 55bb5c9cbb5fe11a90ec2e9e1e0c7c502908cf9a Or will the git-svn-id need to be stripped from the intended commits? I tried this using --dry-run but couldn't tell whether it would try to submit all commits: > git svn dcommit --verbose --dry-run 55bb5c9cbb5fe11a90ec2e9e1e0c7c502908cf9a Committing to http://tracked-svn/trunk ... dcommitted on a detached HEAD because you gave a revision argument. The rewritten commit is: 55bb5c9cbb5fe11a90ec2e9e1e0c7c502908cf9a Thanks for your help.

  • Finding the heaviest length-constrained path in a weighted Binary Tree

    - by Hristo
    UPDATE I worked out an algorithm that I think runs in O(n*k) running time. Below is the pseudo-code: routine heaviestKPath( T, k ) // create 2D matrix with n rows and k columns with each element = -8 // we make it size k+1 because the 0th column must be all 0s for a later // function to work properly and simplicity in our algorithm matrix = new array[ T.getVertexCount() ][ k + 1 ] (-8); // set all elements in the first column of this matrix = 0 matrix[ n ][ 0 ] = 0; // fill our matrix by traversing the tree traverseToFillMatrix( T.root, k ); // consider a path that would arc over a node globalMaxWeight = -8; findArcs( T.root, k ); return globalMaxWeight end routine // node = the current node; k = the path length; node.lc = node’s left child; // node.rc = node’s right child; node.idx = node’s index (row) in the matrix; // node.lc.wt/node.rc.wt = weight of the edge to left/right child; routine traverseToFillMatrix( node, k ) if (node == null) return; traverseToFillMatrix(node.lc, k ); // recurse left traverseToFillMatrix(node.rc, k ); // recurse right // in the case that a left/right child doesn’t exist, or both, // let’s assume the code is smart enough to handle these cases matrix[ node.idx ][ 1 ] = max( node.lc.wt, node.rc.wt ); for i = 2 to k { // max returns the heavier of the 2 paths matrix[node.idx][i] = max( matrix[node.lc.idx][i-1] + node.lc.wt, matrix[node.rc.idx][i-1] + node.rc.wt); } end routine // node = the current node, k = the path length routine findArcs( node, k ) if (node == null) return; nodeMax = matrix[node.idx][k]; longPath = path[node.idx][k]; i = 1; j = k-1; while ( i+j == k AND i < k ) { left = node.lc.wt + matrix[node.lc.idx][i-1]; right = node.rc.wt + matrix[node.rc.idx][j-1]; if ( left + right > nodeMax ) { nodeMax = left + right; } i++; j--; } // if this node’s max weight is larger than the global max weight, update if ( globalMaxWeight < nodeMax ) { globalMaxWeight = nodeMax; } findArcs( node.lc, k ); // recurse left findArcs( node.rc, k ); // recurse right end routine Let me know what you think. Feedback is welcome. I think have come up with two naive algorithms that find the heaviest length-constrained path in a weighted Binary Tree. Firstly, the description of the algorithm is as follows: given an n-vertex Binary Tree with weighted edges and some value k, find the heaviest path of length k. For both algorithms, I'll need a reference to all vertices so I'll just do a simple traversal of the Tree to have a reference to all vertices, with each vertex having a reference to its left, right, and parent nodes in the tree. Algorithm 1 For this algorithm, I'm basically planning on running DFS from each node in the Tree, with consideration to the fixed path length. In addition, since the path I'm looking for has the potential of going from left subtree to root to right subtree, I will have to consider 3 choices at each node. But this will result in a O(n*3^k) algorithm and I don't like that. Algorithm 2 I'm essentially thinking about using a modified version of Dijkstra's Algorithm in order to consider a fixed path length. Since I'm looking for heaviest and Dijkstra's Algorithm finds the lightest, I'm planning on negating all edge weights before starting the traversal. Actually... this doesn't make sense since I'd have to run Dijkstra's on each node and that doesn't seem very efficient much better than the above algorithm. So I guess my main questions are several. Firstly, do the algorithms I've described above solve the problem at hand? I'm not totally certain the Dijkstra's version will work as Dijkstra's is meant for positive edge values. Now, I am sure there exist more clever/efficient algorithms for this... what is a better algorithm? I've read about "Using spine decompositions to efficiently solve the length-constrained heaviest path problem for trees" but that is really complicated and I don't understand it at all. Are there other algorithms that tackle this problem, maybe not as efficiently as spine decomposition but easier to understand? Thanks.

  • How can I prevent default_environment variables from getting set by Capistrano's sudo action?

    My deploy.rb sets some environment variables to use the regular user's local Ruby rather than the system-wide one. set :default_environment, { :PATH => '/home/myapp/.rvm/bin:/home/myapp/.rvm/bin:/home/myapp/.rvm/rubies/ruby-1.9.1-p378/bin:/home/myapp/.rvm/gems/ruby-1.9.1-p378/bin:/home/myapp/.rvm/gems/ruby-1.9.1-p378%global/bin:/home/myapp/bin:/usr/bin:/opt/local/bin:/opt/local/sbin:/usr/local/bin:/usr/local/sbin:/usr/sbin:/sbin:/bin:/usr/games', :RUBY_VERSION => 'ruby-1.9.1-p378', :GEM_HOME => '/home/myapp/.rvm/gems/ruby-1.9.1-p378', :GEM_PATH => '/home/myapp/.rvm/gems/ruby-1.9.1-p378:/home/myapp/.rvm/gems/ruby-1.9.1-p378%global' } Naturally, when a task is using sudo, I would expect the system-wide ruby to be used instead. But it seems the environment variables are being set anyway, which is obviously invalid for the root user and returns an error: executing "sudo -p 'sudo password: ' /etc/init.d/god stop" servers: ["myapp.com"] [myapp.com] executing command command finished failed: "env PATH=/home/myapp/.rvm/bin:/home/myapp/.rvm/bin:/home/myapp/.rvm/rubies/ruby-1.9.1-p378/bin:/home/myapp/.rvm/gems/ruby-1.9.1-p378/bin:/home/myapp/.rvm/gems/ruby-1.9.1-p378%global/bin:/home/myapp/bin:/usr/bin:/opt/local/bin:/opt/local/sbin:/usr/local/bin:/usr/local/sbin:/usr/sbin:/sbin:/bin:/usr/games RUBY_VERSION=ruby-1.9.1-p378 GEM_HOME=/home/myapp/.rvm/gems/ruby-1.9.1-p378 GEM_PATH=/home/myapp/.rvm/gems/ruby-1.9.1-p378:/home/myapp/.rvm/gems/ruby-1.9.1-p378%global sh -c 'sudo -p '\\''sudo password: '\\'' /etc/init.d/god stop'" on myapp.com It makes no difference whether I use capistrano's sudo "system call" or the regular run "sudo system call". How can I avoid this?

  • How to upload files and store them in a server local path when MS SQL SERVER allows remote connectio

    - by user193655
    I am developing a win32 windows application with Delphi and MS SQL Server. it works fine in LAN but I am trying to add the support for SQL Server remote connections (= working with a DB that can be accessed with an external IP, as described in this article: http://support.microsoft.com/default.aspx?scid=kb;EN-US;914277). Basically I have a Table in DB where I keep the DocumentID, the document description and the Document path (like \FILESERVER\MyApplicationDocuments\45.zip). Of course \FILESERVER is a local (LAN) path for the server but not for the client (as I am now trying to add the support for remote connections). So I need a way to access \FILESERVER even if of course I cannot see it in LAN. I found the following T-SQL code snippet that is perfect for the "download trick": SELECT BulkColumn as MyFile FROM OPENROWSET(BULK '\FILESERVER\MyApplicationDocuments\45.zip' , SINGLE_BLOB) AS X With the code above I can download a file on the client. But how to upload it? I need an "Uppload trick" to be able to insert new files, but also to delete or replace existing files. Can anyone suggest? If a trick is not available could you suggest an alternative? Like an extended stored procedure or calling some .net assembly from the server.
