• Mule xml to soap problem

  - by kevfuzz

  Hi, I'm not sure if there many Mule users on here but I'm hoping someone might be able to help me! I'm having a problem calling a webservice from Mule using Axis. I've created a fairly simple example where I have xml in a file being read by Mule, it's then transformed into a Document and sent to the webservice. The relevant code in the mule config looks like this: <inbound> <file:inbound-endpoint path="./files/initial" transformer-refs="FileToString xmlToDom" connector-ref="fileConnector" /> </inbound> <outbound> <pass-through-router> <axis:outbound-endpoint address="http://localhost:8081/holidayService?method=echoXXXX" synchronous="true" style="DOCUMENT" use="LITERAL" /> </pass-through-router> </outbound> However the call for the webservice fails as the above config is generating a SOAP message with an tag just after the tag and closes it just before the tag. The generated SOAP message looks like this: POST /holidayService?method=echoXXXX HTTP/1.1 Content-Type: text/xml X-MULE_ENDPOINT: http://localhost:8081/holidayService?method=echoXXXX SOAPAction: http://localhost:8081/holidayService?method=echoXXXX directory: D:\bea\weblogic92\samples\domains\wl_server\files\processed filename: HolidayRequest.xml method: echoXXXX originalFilename: HolidayRequest.xml style: document use: literal User-Agent: Jakarta Commons-HttpClient/3.1 Host: 127.0.0.1:8081 Content-Length: 1183 <?xml version="1.0" encoding="UTF-8"?> <soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"> <soapenv:Header> <mule:header soapenv:actor="http://www.muleumo.org/providers/soap/1.0" soapenv:mustUnderstand="0" xmlns:mule="http://www.muleumo.org/providers/soap/1.0"> <mule:MULE_CORRELATION_ID>D:\bea\weblogic92\samples\domains\wl_server\files\processed\HolidayRequest.xml</mule:MULE_CORRELATION_ID> <mule:MULE_CORRELATION_GROUP_SIZE>-1</mule:MULE_CORRELATION_GROUP_SIZE> <mule:MULE_CORRELATION_SEQUENCE>-1</mule:MULE_CORRELATION_SEQUENCE> </mule:header> </soapenv:Header> <soapenv:Body> <value0 xsi:type="ns1:DocumentImpl" xmlns="" xmlns:ns1="http://dom.internal.xerces.apache.org.sun.com"> <sch:HolidayRequest xmlns:sch="http://mycompany.com/hr/schemas"> <sch:Holiday> <sch:StartDate>2009-08-13</sch:StartDate> <sch:EndDate>1988-12-12</sch:EndDate> </sch:Holiday> <sch:Employee> <sch:Number>3434</sch:Number> <sch:FirstName>John</sch:FirstName> <sch:LastName>Smith</sch:LastName> </sch:Employee> </sch:HolidayRequest> </value0> </soapenv:Body> </soapenv:Envelope> The webservice works fine in SOAPUI without the tag and from what I've read on the Mule website I don't know why it's being inserted. Any help would be much appreciated, Kevin.

• Tomcat stops responding to JK requests

  - by Bruno Reis

  Hello. I have a nasty issue with load-balanced Tomcat servers that are hanging up. Any help would be greatly appreciated. The system I'm running Tomcat 6.0.26 on HotSpot Server 14.3-b01 (Java 1.6.0_17-b04) on three servers sitting behind another server that acts as load balancer. The load balancer runs Apache (2.2.8-1) + MOD_JK (1.2.25). All of the servers are running Ubuntu 8.04. The Tomcat's have 2 connectors configured: an AJP one, and a HTTP one. The AJP is to be used with the load balancer, while the HTTP is used by the dev team to directly connect to a chosen server (if we have a reason to do so). I have Lambda Probe 1.7b installed on the Tomcat servers to help me diagnose and fix the problem soon to be described. The problem Here's the problem: after about 1 day the application servers are up, JK Status Manager starts reporting status ERR for, say, Tomcat2. It will simply get stuck on this state, and the only fix I've found so far is to ssh the box and restart Tomcat. I must also mention that JK Status Manager takes a lot longer to refresh when there's a Tomcat server in this state. Finally, the "Busy" count of the stuck Tomcat on JK Status Manager is always high, and won't go down per se -- I must restart the Tomcat server, wait, then reset the worker on JK. Analysis Since I have 2 connectors on each Tomcat (AJP and HTTP), I still can connect to the application through the HTTP one. The application works just fine like this, very, very fast. That is perfectly normal, since I'm the only one using this server (as JK stopped delegating requests to this Tomcat). To try to better understand the problem, I've taken a thread dump from a Tomcat which is not responding anymore, and from another one that has been restarted recently (say, 1 hour before). The instance that is responding normally to JK shows most of the TP-ProcessorXXX threads in "Runnable" state, with the following stack trace: java.net.SocketInputStream.socketRead0 ( native code ) java.net.SocketInputStream.read ( SocketInputStream.java:129 ) java.io.BufferedInputStream.fill ( BufferedInputStream.java:218 ) java.io.BufferedInputStream.read1 ( BufferedInputStream.java:258 ) java.io.BufferedInputStream.read ( BufferedInputStream.java:317 ) org.apache.jk.common.ChannelSocket.read ( ChannelSocket.java:621 ) org.apache.jk.common.ChannelSocket.receive ( ChannelSocket.java:559 ) org.apache.jk.common.ChannelSocket.processConnection ( ChannelSocket.java:686 ) org.apache.jk.common.ChannelSocket$SocketConnection.runIt ( ChannelSocket.java:891 ) org.apache.tomcat.util.threads.ThreadPool$ControlRunnable.run ( ThreadPool.java:690 ) java.lang.Thread.run ( Thread.java:619 ) The instance that is stuck show most (all?) of the TP-ProcessorXXX threads in "Waiting" state. These have the following stack trace: java.lang.Object.wait ( native code ) java.lang.Object.wait ( Object.java:485 ) org.apache.tomcat.util.threads.ThreadPool$ControlRunnable.run ( ThreadPool.java:662 ) java.lang.Thread.run ( Thread.java:619 ) I don't know of the internals of Tomcat, but I would infer that the "Waiting" threads are simply threads sitting on a thread pool. So, if they are threads waiting inside of a thread pool, why wouldn't Tomcat put them to work on processing requests from JK? Solution? So, as I've stated before, the only fix I've found is to stop the Tomcat instance, stop the JK worker, wait the latter's busy count slowly go down, start Tomcat again, and enable the JK worker once again. What is causing this problem? How should I further investigate it? What can I do to solve it? Thanks in advance.

• How to sanely configure security policy in Tomcat 6

  - by Chas Emerick

  I'm using Tomcat 6.0.24, as packaged for Ubuntu Karmic. The default security policy of Ubuntu's Tomcat package is pretty stringent, but appears straightforward. In /var/lib/tomcat6/conf/policy.d, there are a variety of files that establish default policy. Worth noting at the start: I've not changed the stock tomcat install at all -- no new jars into its common lib directory(ies), no server.xml changes, etc. Putting the .war file in the webapps directory is the only deployment action. the web application I'm deploying fails with thousands of access denials under this default policy (as reported to the log thanks to the -Djava.security.debug="access,stack,failure" system property). turning off the security manager entirely results in no errors whatsoever, and proper app functionality What I'd like to do is add an application-specific security policy file to the policy.d directory, which seems to be the recommended practice. I added this to policy.d/100myapp.policy (as a starting point -- I would like to eventually trim back the granted permissions to only what the app actually needs): grant codeBase "file:${catalina.base}/webapps/ROOT.war" { permission java.security.AllPermission; }; grant codeBase "file:${catalina.base}/webapps/ROOT/-" { permission java.security.AllPermission; }; grant codeBase "file:${catalina.base}/webapps/ROOT/WEB-INF/-" { permission java.security.AllPermission; }; grant codeBase "file:${catalina.base}/webapps/ROOT/WEB-INF/lib/-" { permission java.security.AllPermission; }; grant codeBase "file:${catalina.base}/webapps/ROOT/WEB-INF/classes/-" { permission java.security.AllPermission; }; Note the thrashing around attempting to find the right codeBase declaration. I think that's likely my fundamental problem. Anyway, the above (really only the first two grants appear to have any effect) almost works: the thousands of access denials are gone, and I'm left with just one. Relevant stack trace: java.security.AccessControlException: access denied (java.io.FilePermission /var/lib/tomcat6/webapps/ROOT/WEB-INF/classes/com/foo/some-file-here.txt read) java.security.AccessControlContext.checkPermission(AccessControlContext.java:323) java.security.AccessController.checkPermission(AccessController.java:546) java.lang.SecurityManager.checkPermission(SecurityManager.java:532) java.lang.SecurityManager.checkRead(SecurityManager.java:871) java.io.File.exists(File.java:731) org.apache.naming.resources.FileDirContext.file(FileDirContext.java:785) org.apache.naming.resources.FileDirContext.lookup(FileDirContext.java:206) org.apache.naming.resources.ProxyDirContext.lookup(ProxyDirContext.java:299) org.apache.catalina.loader.WebappClassLoader.findResourceInternal(WebappClassLoader.java:1937) org.apache.catalina.loader.WebappClassLoader.findResource(WebappClassLoader.java:973) org.apache.catalina.loader.WebappClassLoader.getResource(WebappClassLoader.java:1108) java.lang.ClassLoader.getResource(ClassLoader.java:973) I'm pretty convinced that the actual file that's triggering the denial is irrelevant -- it's just some properties file that we check for optional configuration parameters. What's interesting is that: it doesn't exist in this context the fact that the file doesn't exist ends up throwing a security exception, rather than java.io.File.exists() simply returning false (although I suppose that's just a matter of the semantics of the read permission). Another workaround (besides just disabling the security manager in tomcat) is to add an open-ended permission to my policy file: grant { permission java.security.AllPermission; }; I presume this is functionally equivalent to turning off the security manager. I suppose I must be getting the codeBase declaration in my grants subtly wrong, but I'm not seeing it at the moment.

• Maven not setting classpath for dependencies properly

  - by Matthew

  OS name: "linux" version: "2.6.32-27-generic" arch: "i386" Family: "unix" Apache Maven 2.2.1 (r801777; 2009-08-06 12:16:01-0700) Java version: 1.6.0_20 I am trying to use the mysql dependency in with maven in ubuntu. If I move the "mysql-connector-java-5.1.14.jar" file that maven downloaded into my $JAVA_HOME/jre/lib/ext/ folder, everything is fine when I run the jar. I think I should be able to just specify the dependency in the pom.xml file and maven should take care of setting the classpath for the dependency jars automatically. Is this incorrect? My pom.xml file looks like this: <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.ion.common</groupId> <artifactId>TestPreparation</artifactId> <version>1.0-SNAPSHOT</version> <packaging>jar</packaging> <name>TestPrep</name> <url>http://maven.apache.org</url> <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> </properties> <build> <plugins> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-jar-plugin</artifactId> <configuration> <archive> <manifest> <addClasspath>true</addClasspath> <mainClass>com.ion.common.App</mainClass> </manifest> </archive> </configuration> </plugin> </plugins> </build> <dependencies> <!-- JUnit testing dependency --> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>3.8.1</version> <scope>test</scope> </dependency> <!-- MySQL database driver --> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>5.1.14</version> <scope>compile</scope> </dependency> </dependencies> </project> The command "mvn package" builds it without any problems, and I can run it, but when the application attempts to access the database, this error is presented: java.lang.ClassNotFoundException: com.mysql.jdbc.Driver at java.net.URLClassLoader$1.run(URLClassLoader.java:217) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:205) at java.lang.ClassLoader.loadClass(ClassLoader.java:321) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:294) at java.lang.ClassLoader.loadClass(ClassLoader.java:266) at java.lang.Class.forName0(Native Method) at java.lang.Class.forName(Class.java:186) at com.ion.common.Functions.databases(Functions.java:107) at com.ion.common.App.main(App.java:31) The line it is failing on is: Class.forName("com.mysql.jdbc.Driver"); Can anyone tell me what I'm doing wrong or how to fix it?

• Why only one video shows up in ASP.NET Video panel ?

  - by user284523

  It is possible to have multiple videos with Flowplayer http://flowplayer.org/demos/installation/multiple-players.html To do so in ASP.NET DYNAMICALLY, one has to use a Panel (see http://idevwebs.com/Default.aspx?id=25): <%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <!-- A minimal Flowplayer setup to get you started --> <!-- include flowplayer JavaScript file that does Flash embedding and provides the Flowplayer API. --> <script type="text/javascript" src="flowplayer-3.1.4.min.js"></script> <!-- page title --> <title>Minimal Flowplayer setup</title> </head><body> <form id="form1" runat="server"> <div id="page"> <h1>Minimal Flowplayer setup</h1> <p>View commented source code to get familiar with Flowplayer installation.</p> <!-- this A tag is where your Flowplayer will be placed. it can be anywhere --> <!-- player #1 --> <asp:Panel ID="panelVideo" runat="server"> </asp:Panel> <!-- this will install flowplayer inside previous A- tag. --> <script type="text/javascript"> flowplayer("player", "flowplayer-3.1.5.swf"); </script> <!-- after this line is purely informational stuff. does not affect on Flowplayer functionality --> <p> If you are running these examples <strong>locally</strong> and not on some webserver you must edit your <a href="http://www.macromedia.com/support/documentation/en/flashplayer/help/settings_manager04.html"> Flash security settings</a>. </p> <p class="less"> Select "Edit locations" &gt; "Add location" &gt; "Browse for files" and select flowplayer-x.x.x.swf you just downloaded. </p> <h2>Documentation</h2> <p> <a href="http://flowplayer.org/documentation/installation/index.html">Flowplayer installation</a> </p> <p> <a href="http://flowplayer.org/documentation/configuration/index.html">Flowplayer configuration</a> </p> <p> See this identical page on <a href="http://flowplayer.org/demos/example/index.htm">Flowplayer website</a> </p> </div> </form> </body></html> and then add video anchor dynamically public partial class _Default : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { this.panelVideo.Controls.Add(new LiteralControl("<a href=\"" + "http://blip.tv/file/get/" + "KimAronson-TwentySeconds58192" + ".flv\" style=\"display:block;width:388px;height:230px\" id=\"player\"></a>")); this.panelVideo.Controls.Add(new LiteralControl("<a href=\"" + "http://blip.tv/file/get/" + "KimAronson-TwentySeconds67463" + ".flv\" style=\"display:block;width:388px;height:230px\" id=\"player\"></a>")); } } But it works only partially as the first video shows up not both.

  Hi, I have the following SVG source code that generates a number of boxes with texts: <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE svg PUBLIC "-//W3C//DTD SVG 1.0//EN" "http://www.w3.org/TR/2001/REC-SVG-20050904/DTD/svg11.dtd"> <svg xmlns="http://www.w3.org/2000/svg" version="1.1" xmlns:xlink="http://www.w3.org/1999/xlink" width="600" height="600"> <defs> </defs> <title>Draw</title> <g transform="translate(50,40)"> <rect width="80" height="30" x="0" y="-20" style="stroke: black; stroke-opacity: 1; stroke-width: 1; fill: #9dc2de" /> <text text-anchor="middle" x="40">Text</text> </g> <g transform="translate(150,40)"> <rect width="80" height="30" x="0" y="-20" style="stroke: black; stroke-opacity: 1; stroke-width: 1; fill: #9dc2de" /> <text text-anchor="middle" x="40">Text 2</text> </g> <g transform="translate(250,40)"> <rect width="80" height="30" x="0" y="-20" style="stroke: black; stroke-opacity: 1; stroke-width: 1; fill: #9dc2de" /> <text text-anchor="middle" x="40">Text 3</text> </g> </svg> As you can see, I repeated the <g></g> three times to get three such boxes, when SVG has <defs> and <use> elements that allow reusing elements using id references instead of repeating their definitions. Something like: <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE svg PUBLIC "-//W3C//DTD SVG 1.0//EN" "http://www.w3.org/TR/2001/REC-SVG-20050904/DTD/svg11.dtd"> <svg xmlns="http://www.w3.org/2000/svg" version="1.1" xmlns:xlink="http://www.w3.org/1999/xlink" width="600" height="600"> <defs> <marker style="overflow:visible;fill:inherit;stroke:inherit" id="Arrow1Mend" refX="0.0" refY="0.0" orient="auto"> <path transform="scale(0.4) rotate(180) translate(20,0)" style="fill-rule:evenodd;stroke-width:2.0pt;marker-start:none;" d="M 0.0,-15.0 L -20.5,0.0 L 0.0,15.0 "/> </marker> <line marker-end="url(#Arrow1Mend)" id="systemthread" x1="40" y1="10" x2="40" y2="410" style="stroke: black; stroke-dasharray: 5, 5; stroke-width: 1; "/> </defs> <title>Draw</title> <use xlink:href="#systemthread" transform="translate(50,40)" /> <use xlink:href="#systemthread" transform="translate(150,40)" /> <use xlink:href="#systemthread" transform="translate(250,40)" /> </svg> Unfortunately I can't do this with the first SVG code since I need the texts to be different for each box, while the <use> tag simply duplicates 100% what's defined in <defs>. Is there any way to use <defs> and <use> with some kind of parameters/arguments mechanism like function calls?

  I'm using Eclipse 3.5, Maven 2, m2eclipse and Tomcat 6.

• Silverlight: Binding a custom control to an arbitrary object

  - by Ryan Bates

  I am planning on writing a hierarchical organizational control, similar to an org chart. Several org chart implementations are out there, but not quite fit what I have in mind. Binding fields in a DataTemplate to a custom object does not seem to work. I started with a generic, custom control, i.e. public class NodeBodyBlock : ContentControl { public NodeBodyBlock() { this.DefaultStyleKey = typeof(NodeBodyBlock); } } It has a simple style in generic.xaml: <Style TargetType="org:NodeBodyBlock"> <Setter Property="Width" Value="200" /> <Setter Property="Height" Value="100" /> <Setter Property="Background" Value="Lavender" /> <Setter Property="FontSize" Value="11" /> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="org:NodeBodyBlock"> <Border Width="{TemplateBinding Width}" Height="{TemplateBinding Height}" Background="{TemplateBinding Background}" CornerRadius="4" BorderBrush="Black" BorderThickness="1" > <Grid> <VisualStateManager/> ... clipped for brevity </VisualStateManager.VisualStateGroups> <ContentPresenter Content="{TemplateBinding Content}" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" /> </Grid> </Border> </ControlTemplate> </Setter.Value> </Setter> </Style> My plan now is to be able to use this common definition as a base definition of sorts, with customized version of it used to display different types of content. A simple example would be to use this on a user control with the following style: <Style TargetType="org:NodeBodyBlock" x:Key="TOCNode2"> <Setter Property="ContentTemplate"> <Setter.Value> <DataTemplate> <StackPanel> <TextBlock Text="{Binding Path=NodeTitle}"/> </StackPanel> </DataTemplate> </Setter.Value> </Setter> </Style> and an instance defined as <org:NodeBodyBlock Style="{StaticResource TOCNode2}" x:Name="stTest" DataContext="{StaticResource DummyData}" /> The DummyData is defined as <toc:Node NodeNumber="mynum" NodeStatus="A" NodeTitle="INLine Node Title!" x:Key="DummyData"/> With a simple C# class behind it, where each of the fields is a public property. When running the app, the Dummy Data values simply do not show up in the GUI. A trivial test such as <TextBlock Text="{Binding NodeTitle}" DataContext="{StaticResource DummyData}"/> works just fine. Any ideas around where I am missing the plot?

• Hibernate: update on parent-child relationship causes duplicate children

  - by TimmyJ

  I have a parent child relationship in which the parent has a collection of children (a set to be specific). The child collection is setup with cascade="all-delete-orphan". When I initially save the parent element everything works as expected. However, when I update the parent and save again, all the children are re-saved. This behavior leads me to believe that the parent is losing its reference to the collection of children, and therefore when persisting all the children are re-saved. It seems the only way to fix this is to not use the setter method of this child collection, but unfortunately this setter is called implicitly in my application (Spring MVC is used to bind a multi-select form element to this collection, and the setter is called by spring on the form submission). Overwriting this setter to not lose the reference (ie, do a colleciton.clear() and collection.addAll(newCollection) rather than collection = newCollection) is apparently a hibernate no-no, as is pointed out here: https://forum.hibernate.org/viewtopic.php?t=956859 Does anyone know how to circumvent this problem? I've posted some of my code below. The parent hibernate configuration: <hibernate-mapping package="org.fstrf.masterpk.domain"> <class name="ReportCriteriaBean" table="masterPkReportCriteria"> <id name="id" column="id"> <generator class="org.hibernate.id.IncrementGenerator" /> </id> <set name="treatmentArms" table="masterPkTreatmentArms" sort="org.fstrf.masterpk.domain.RxCodeComparator" lazy="false" cascade="all-delete-orphan" inverse="true"> <key column="runid"/> <one-to-many class="TreatmentArm"/> </set> </class> </hibernate-mapping> The parent object: public class ReportCriteriaBean{ private Integer id; private Set<TreatmentArm> treatmentArms; public Integer getId() { return id; } public void setId(Integer id) { this.id = id; } public Set<TreatmentArm> getTreatmentArms() { return treatmentArms; } public void setTreatmentArms(Set<TreatmentArm> treatmentArms) { this.treatmentArms = treatmentArms; if(this.treatmentArms != null){ for(TreatmentArm treatmentArm : this.treatmentArms){ treatmentArm.setReportCriteriaBean(this); } } } The child hibernate configuration: <hibernate-mapping package="org.fstrf.masterpk.domain"> <class name="TreatmentArm" table="masterPkTreatmentArms"> <id name="id" column="id"> <generator class="org.hibernate.id.IncrementGenerator" /> </id> <many-to-one name="reportCriteriaBean" class="ReportCriteriaBean" column="runId" not-null="true" /> <property name="rxCode" column="rxCode" not-null="true"/> </class> </hibernate-mapping> The child object: public class TreatmentArm { private Integer id; private ReportCriteriaBean reportCriteriaBean; private String rxCode; public Integer getId() { return id; } public void setId(Integer id) { this.id = id; } public ReportCriteriaBean getReportCriteriaBean() { return reportCriteriaBean; } public void setReportCriteriaBean(ReportCriteriaBean reportCriteriaBean) { this.reportCriteriaBean = reportCriteriaBean; } public String getRxCode() { return rxCode; } public void setRxCode(String rxCode) { this.rxCode = rxCode; } }

• Fragment method and socket.io

  - by Tolgay Toklar

  I have a method,this method updates an array list in fragment.I can call this method in main activity like this public void getFromUser(String message) { addMessageToFragment("ok"); } public void addMessageToFragment(String message) { Log.w("Step 1",message); frgObj.addMessageToList("asd"); } getFromUser is calling from fragment(when user presses the button) this is working as well.But I am using socket.io in my app,when I try to call this method from socket.io,app is not working. public void on(String event, IOAcknowledge ack, Object... args) { try{ addMessageToFragment("ok"); } catch (JSONException e) {} } When this callback function calls,app is giving this errors: 08-19 11:57:24.813: W/System.err(4962): io.socket.SocketIOException: Exception was thrown in on(String, JSONObject[]). 08-19 11:57:24.813: W/System.err(4962): Message was: 5:::{"name":"listele","args":[{"mesaj":"123","gonderen":"781722165-tolgay007-DKSMIcIYGahPuKXriM83","alici":"tolgay007","blck_id":"781722165-tolgay007","out_username":"Anony-781722","ars_status":1,"longinf":"3aqghef","a_status":1}]} 08-19 11:57:24.813: W/System.err(4962): at io.socket.IOConnection.transportMessage(IOConnection.java:702) 08-19 11:57:24.813: W/System.err(4962): at io.socket.WebsocketTransport.onMessage(WebsocketTransport.java:82) 08-19 11:57:24.813: W/System.err(4962): at org.java_websocket.client.WebSocketClient.onWebsocketMessage(WebSocketClient.java:361) 08-19 11:57:24.813: W/System.err(4962): at org.java_websocket.WebSocketImpl.deliverMessage(WebSocketImpl.java:565) 08-19 11:57:24.813: W/System.err(4962): at org.java_websocket.WebSocketImpl.decodeFrames(WebSocketImpl.java:331) 08-19 11:57:24.813: W/System.err(4962): at org.java_websocket.WebSocketImpl.decode(WebSocketImpl.java:152) 08-19 11:57:24.813: W/System.err(4962): at org.java_websocket.client.WebSocketClient.interruptableRun(WebSocketClient.java:247) 08-19 11:57:24.823: W/System.err(4962): at org.java_websocket.client.WebSocketClient.run(WebSocketClient.java:193) 08-19 11:57:24.823: W/System.err(4962): at java.lang.Thread.run(Thread.java:841) 08-19 11:57:24.823: W/System.err(4962): Caused by: android.view.ViewRootImpl$CalledFromWrongThreadException: Only the original thread that created a view hierarchy can touch its views. 08-19 11:57:24.823: W/System.err(4962): at android.view.ViewRootImpl.checkThread(ViewRootImpl.java:6094) 08-19 11:57:24.823: W/System.err(4962): at android.view.ViewRootImpl.focusableViewAvailable(ViewRootImpl.java:2800) 08-19 11:57:24.823: W/System.err(4962): at android.view.ViewGroup.focusableViewAvailable(ViewGroup.java:650) 08-19 11:57:24.823: W/System.err(4962): at android.view.ViewGroup.focusableViewAvailable(ViewGroup.java:650) 08-19 11:57:24.823: W/System.err(4962): at android.view.ViewGroup.focusableViewAvailable(ViewGroup.java:650) 08-19 11:57:24.823: W/System.err(4962): at android.view.ViewGroup.focusableViewAvailable(ViewGroup.java:650) 08-19 11:57:24.823: W/System.err(4962): at android.view.ViewGroup.focusableViewAvailable(ViewGroup.java:650) 08-19 11:57:24.823: W/System.err(4962): at android.view.ViewGroup.focusableViewAvailable(ViewGroup.java:650) 08-19 11:57:24.823: W/System.err(4962): at android.view.ViewGroup.focusableViewAvailable(ViewGroup.java:650) 08-19 11:57:24.823: W/System.err(4962): at android.view.View.setFlags(View.java:8878) 08-19 11:57:24.823: W/System.err(4962): at android.view.View.setFocusableInTouchMode(View.java:6114) 08-19 11:57:24.823: W/System.err(4962): at android.widget.AdapterView.checkFocus(AdapterView.java:718) 08-19 11:57:24.823: W/System.err(4962): at android.widget.AdapterView$AdapterDataSetObserver.onChanged(AdapterView.java:813) 08-19 11:57:24.823: W/System.err(4962): at android.widget.AbsListView$AdapterDataSetObserver.onChanged(AbsListView.java:6280) 08-19 11:57:24.823: W/System.err(4962): at android.database.DataSetObservable.notifyChanged(DataSetObservable.java:37) 08-19 11:57:24.823: W/System.err(4962): at android.widget.BaseAdapter.notifyDataSetChanged(BaseAdapter.java:50) 08-19 11:57:24.823: W/System.err(4962): at android.widget.ArrayAdapter.notifyDataSetChanged(ArrayAdapter.java:286) 08-19 11:57:24.823: W/System.err(4962): at com.impact.ribony.ConversationFragment.addMessageToList(ConversationFragment.java:91) 08-19 11:57:24.823: W/System.err(4962): at com.impact.ribony.MainActivity.addMessageToFragment(MainActivity.java:344) 08-19 11:57:24.823: W/System.err(4962): at com.impact.ribony.MainActivity$2.on(MainActivity.java:183) 08-19 11:57:24.823: W/System.err(4962): at io.socket.IOConnection.on(IOConnection.java:908) 08-19 11:57:24.883: W/System.err(4962): at io.socket.IOConnection.transportMessage(IOConnection.java:697) I didn't understand this error.What can be cause this error ?

• How do I run Firefox OS as a standalone application?

  - by JamesTheAwesomeDude

  I got the add-on for the Firefox OS simulator, and it works great! It even keeps functioning after Firefox is closed, so I can save processing power for other things. I'd like to run it as a standalone application, so that I don't even have to open Firefox in the first place. I've gone to the System Monitor, and it says that the process (I guessed which by CPU usage and filename) was started via /home/james/.mozilla/firefox-trunk/vkuuxfit.default/extensions/[email protected]/resources/r2d2b2g/data/linux64/b2g/plugin-container 3386 true tab, so I tried running that in the Terminal (after I'd closed the simulator, of course,) but it gives this: james@james-OptiPlex-GX620:~/.mozilla/firefox-trunk/vkuuxfit.default/extensions/[email protected]/resources/r2d2b2g/data/linux64/b2g$ ./plugin-container 3386 true tab ./plugin-container: error while loading shared libraries: libxpcom.so: cannot open shared object file: No such file or directory james@james-OptiPlex-GX620:~/.mozilla/firefox-trunk/vkuuxfit.default/extensions/[email protected]/resources/r2d2b2g/data/linux64/b2g$ What should I do? Is what I'm attempting even possible? (It should be, since the simulator kept running even after Firefox itself was closed...) NOTE: I've tried chmod u+sx plugin-container, but that didn't help.

• Issue with gpg agent in Ubuntu 12.04 after installing gnome3 shell

  - by Jeroen

  I just did a fresh install of Ubuntu 12.04. Initially things were working. But after I installed some software, the 'gpg agent' is unresponsive. I suspect it has something to do with upgrades that I downloaded from the gnome 3 ppa. When I try to sign a package, it terminates with: gpg: problem with the agent - disabling agent use debsign: gpg error occurred! Aborting.... debuild: fatal error at line 1271: running debsign failed The GPG gui tool (called "Passwords and Keys" or seahorse) isn't starting anymore either. When I click it, it tries to start and then gives up and dies after a couple of seconds. I am not sure where to look for log files of gpg agent. The only thing that I see in /var/log is in auth.log that says: May 1 20:04:14 jeroen-ubuntu gnome-keyring-daemon[1997]: couldn't create prompt for gnupg passphrase: GDBus.Error:org.freedesktop.DBus.Error.ServiceUnknown: The name org.gnome.keyring.SystemPrompter was not provided by any .service files Not sure if it is related, but when I try to start seahorse from the command line, I get: jeroen@jeroen-ubuntu:~$ seahorse (seahorse:4828): GLib-GIO-ERROR **: Settings schema 'org.gnome.crypto.pgp' is not installed Edit: I fixed the seahorse GUI by manually downloading and reinstalling gnome-keyring version from precise instead of the ppa. However, I still cannot sign packages.

• defunct dbus-daemon zombie freezes login for 30 seconds

  - by oldenburgb

  I'm running Ubuntu 12.04.2 LTS (Precise Pangolin) and noticed a 30 second delay whenever i log into my server via ssh or perform any kind of login via sudo on that machine. I can provoke immediate execution by killing the defunct dbus-daemon showing up during the delay: output of ps fax |grep dbus 19222 ? Ss 0:00 dbus-daemon --system --fork --activation=upstart 19752 ? Z 0:00 \_ [dbus-daemon] <defunct> taping into the dbus using dbus-monitor --system i'm getting: signal sender=org.freedesktop.DBus -> dest=(null destination) serial=7 path=/org/freedesktop/DBus; interface=org.freedesktop.DBus; member=NameOwnerChanged string ":1.4" string "" string ":1.4" each login. Stopping the dbus service eliminates this problem but probably causes many other... I'm not running xorg on the machine but the packages are present for X11 forwarding capabilities. I've ruled out the common motd script delay and ssh "UseDNS no" fixes one finds when looking up login delay issues. Many thanks in advance for any help with this, it's been driving me crazy ;-)

• Notify-osd notifications appear unthemed in top-left corner (ubuntu 13.10)

  - by Wehlutyk

  Problem I recently upgraded from 13.04 to 13.10, and suddenly notification bubbles don't appear themed as usual in the upper right corner, but they appear as white text on blue background in the upper-left corner. It looks like this: Unsuccesful attempts to fix it I tried reinstalling unity, notify-osd, ubuntu-desktop removed notification-daemon which was installed, none of that fixes it. In fact running ps aux | grep notify-osd shows that notify-osd isn't even running. But when I try to start it manually by running /usr/lib/x86_64-linux-gnu/notify-osd I get: ** (notify-osd:4618): WARNING **: Another instance has already registered org.freedesktop.Notifications ** (notify-osd:4618): WARNING **: Could not register instance If I understand well, the instance is registered by the /usr/share/dbus-1/services/org.freedesktop.Notifications.service file, which right now contains: [D-BUS Service] Name=org.freedesktop.Notifications Exec=/usr/lib/x86_64-linux-gnu/notify-osd Renaming or deleting that file (and rebooting) has no effect whatsoever (and it is not recreated automatically). This is not a duplicate of No notifications from notify-osd on 13.10 (and by the way I purged gnome-flashback-session along with notification-daemon) Question(s) How can I debug this? How can I get notifications to come back to normal? If additional debug information is needed, I'll be happy to add it (just that I can't find any more).

• Hudson.. another Continuous Integration tool

  - by Narendra Tiwari

  In my previous posts I discussed about Cruisecontrol.net and its legacy support to .Net development. Hudson  is yet another continuous integration tool. Hudson is also free like CCNet and built in java. - CCNet has its legacy support to .Net applications where as Hudson can be easily configured on both the environments (.Net and Java). - One of the major differences in CCNet and Hudson is the richer GUI of Hudson provide user interactive screens for project configuration where as in CCNet we have to play with a few xml configuration files. Both the tools are capable of providing basic features of continuous integration e.g.:- - Source Control configuration - Code Compilation/Build - Ad hoc plugin tools to be configured along with compilation Support for adhoc tools seems to be bigger with CCNet e.g. There are almost every source control plugin available with CCNet where as Hudson has support for limited source control servers. Basically there is an interseting point to see is that there are 2 major partsof whole CI system one performed by build tool and rest. Build tool takes care of all adhoc plugin tools  so no matter if CI tool does not have plugin for that tool if thet tools provides command line support that can be configured in build tool and that build tool is then configured with CI tool inturn. For example if I have a build script configured in MSBuild and CCNet can be easily switched to Hudson. Here we need not to change anything in build script we just need to configure MSBuild on Hudson and pass the path of script file and thats it... all is same. Hudson Resources:- - https://hudson.dev.java.net/ - http://wiki.hudson-ci.org/display/HUDSON/Meet+Hudson - http://wiki.hudson-ci.org/display/HUDSON/Plugins - http://callport.blogspot.com/2009/02/hudson-for-net-projects.html Java support on CCNet http://confluence.public.thoughtworks.org/display/CC/Getting+Started+With+CruiseControl?focusedCommentId=19988484#comment-19988484 Please share your thoughts...

When I try to run it via Terminal, the following error messages are printed and the program aborts: $ qreator ** (qreator:3859): WARNING **: Couldn't connect to accessibility bus: Failed to connect to socket /tmp/dbus-Gh2FPHrMr2: Connection refused No handlers could be found for logger "qreator_lib" Traceback (most recent call last): File "/usr/bin/qreator", line 47, in <module> qreator.main() File "/usr/lib/python2.7/dist-packages/qreator/__init__.py", line 63, in main window = QreatorWindow.QreatorWindow() File "/usr/lib/python2.7/dist-packages/qreator_lib/Window.py", line 48, in __new__ new_object.finish_initializing(builder) File "/usr/lib/python2.7/dist-packages/qreator/QreatorWindow.py", line 79, in finish_initializing self.init_qr_types() File "/usr/lib/python2.7/dist-packages/qreator/QreatorWindow.py", line 135, in init_qr_types self.qr_types = [d(self.update_qr_code) for d in QRCodeType.dataformats] File "/usr/lib/python2.7/dist-packages/qreator/qrcodes/QRCodeType.py", line 71, in __init__ self.create_widget() # pylint: disable=E1101 File "/usr/lib/python2.7/dist-packages/qreator/qrcodes/QRCodeLocation.py", line 29, in create_widget self.widget = QRCodeLocationGtk(self.qr_code_update_func) File "/usr/lib/python2.7/dist-packages/qreator/qrcodes/QRCodeLocationGtk.py", line 49, in __init__ latitude, longitude = get_current_location() File "/usr/lib/python2.7/dist-packages/qreator/qrcodes/QRCodeLocationGtk.py", line 109, in get_current_location '/org/freedesktop/Geoclue/Providers/Hostip') File "/usr/lib/python2.7/dist-packages/dbus/bus.py", line 241, in get_object follow_name_owner_changes=follow_name_owner_changes) File "/usr/lib/python2.7/dist-packages/dbus/proxies.py", line 248, in __init__ self._named_service = conn.activate_name_owner(bus_name) File "/usr/lib/python2.7/dist-packages/dbus/bus.py", line 180, in activate_name_owner self.start_service_by_name(bus_name) File "/usr/lib/python2.7/dist-packages/dbus/bus.py", line 278, in start_service_by_name 'su', (bus_name, flags))) File "/usr/lib/python2.7/dist-packages/dbus/connection.py", line 651, in call_blocking message, timeout) dbus.exceptions.DBusException: org.freedesktop.DBus.Error.ServiceUnknown: The name org.freedesktop.Geoclue.Providers.Hostip was not provided by any .service files How can I fix this ?

• Cannot install mysql-server on ubuntu 11.10 by either synaptic or terminal

  - by roopunk

  I've been facing this problem with installing some other packages too. Inside terminal I type: sudo apt-get install mysql-server and I get the following: Reading package lists...

• Help, broken Gsettings

  - by Rene

  I was trying to disable the global menu as per http://ubuntuhandbook.org/index.php/2013/07/disable-global-menu-on-ubuntu-13-10-saucy/#comment-8612, but while it didn't change anything, after running the autoremove command unity-tweak-tool broke. Obviously my first reaction was to re-install the removed package but it remains broken. TBH I don't know if it is even related or just a coincidence. When I start it from the launcher it just blinks and disappear. When I start it from terminal I get this error: $ gnome-tweak-tool WARNING : Shell not installed or running WARNING : Error detecting shell Traceback (most recent call last): File "/usr/lib/python2.7/dist-packages/gtweak/tweaks/tweak_shell_extensions.py", line 199, in __init__ raise Exception("Shell not running or DBus service not available") Exception: Shell not running or DBus service not available INFO : GSettings missing key org.gnome.nautilus.desktop (key computer-icon-visible) WARNING : Shell not running None INFO : GSettings missing key org.gnome.mutter (key workspaces-only-on-primary) Segmentation fault (core dumped) I had a look with dconf-editor if I could just add the missing key, but apparently keys aren't meant to be added "by hand". So how can I fix this? I'd rather prefer not having to reinstall everything. Which package is broken, can I just reinstall that? EDIT: I found by being root gnome-tweak-tool no longer crashed so possibly a permission issue somewhere. I don't know that I changed any permissions. Another related problem, actually the reason I noticed the problem at all, is that unity-tweak-tool seem no longer to want to save the values edited. I normally just have the Unity launcher on the primary display but wanted to check what it was like having it on both. I didn't like it so I went into unity-tweak-tool to set it back - but regardless how many time I tick "only primary display" it never changes anything. What does the Unity-tweak-tool actually change and can I do this directly somehow?

• Why do my LWJGL fonts have dots and lines around them?

  - by Jordan

  When we render fonts there are weird dots and lines around the text. I have no idea why this would happen. Here is an image of what it looks like: Our font class looks like this: package me.NJ.ComputerTycoon.Font; import me.NJ.ComputerTycoon.BaseObjects.UDim2; import org.lwjgl.opengl.Display; import org.newdawn.slick.Color; import org.newdawn.slick.TrueTypeFont; public class Font { public TrueTypeFont font; private int fontSize = 18; private String fontName = "Calibri"; private int fontStyle = java.awt.Font.BOLD; public Font(String fontName, int fontStyle, int fontSize) { font = new TrueTypeFont(new java.awt.Font(fontName, fontStyle, fontSize), true); //font. } public Font(int fontStyle, int fontSize) { font = new TrueTypeFont(new java.awt.Font(fontName, fontStyle, fontSize), true); } public Font(int fontSize) { font = new TrueTypeFont(new java.awt.Font(fontName, fontStyle, fontSize), true); } public Font() { font = new TrueTypeFont(new java.awt.Font(fontName, fontStyle, fontSize), true); } public void drawString(int x, int y, String s, Color color){ this.font.drawString(x, y, s, color); } public void drawString(int x, int y, String s){ this.font.drawString(x, y, s); } public void drawString(float x, float y, String s, Color color){ this.font.drawString(x, y, s, color); } public void drawString(float x, float y, String s){ this.font.drawString(x, y, s); } public void drawString(UDim2 udim, String s){ this.font.drawString((Display.getWidth() * udim.getX().getScale()) + udim.getX().getOffset(), (Display.getHeight() * udim.getY().getScale()) + udim.getY().getOffset(), s); } public String getFontName(){ return this.fontName; } public int getFontSize(){ return this.fontSize; } public TrueTypeFont getFont(){ return this.font; } } What could be causing this?

• Apache config file. Redirect permanent gives 403 error

  - by Homunculus Reticulli

  I am changing my domain from foo.com to foobar.org. I used a Redirect permanent in my apache config file, and then restarted apache. When I try to access the old domain foo.com, I get a 403 error. This is what my apache config file looks like: <VirtualHost *:80> ServerName foo.com #ServerAlias www.foo.com #ServerAdmin [email protected] Redirect permanent / http://www.foobar.org/ DocumentRoot /path/to/project/foo/web DirectoryIndex index.php # CustomLog with format nickname LogFormat "%h %l %u %t \"%r\" %>s %b" common CustomLog "|/usr/bin/cronolog /var/log/apache2/%Y%m.foo.access.log" common LogLevel notice ErrorLog "|/usr/bin/cronolog /var/log/apache2/%Y%m.foo.errors.log" <Directory /> Order Deny,Allow Deny from all </Directory> <Files ~ "^\.ht"> Order allow,deny Deny from all </Files> <Directory /path/to/project/foo/web> Options -Indexes -Includes AllowOverride All Allow from All RewriteEngine On # We check if the .html version is here (cacheing) RewriteRule ^$ index.html [QSA] RewriteRule ^([^.])$ $1.html [QSA] RewriteCond %{REQUEST_FILENAME} !-f # No, so we redirect to our front end controller RewriteRule ^(.*)$ index.php [QSA,L] </Directory> <Directory /path/to/project/foo/web/uploads> Options -ExecCGI -FollowSymLinks -Indexes -Includes AllowOverride None php_flag engine off </Directory> Alias /sf /lib/vendor/symfony/symfony-1.3.8/data/web/sf <Directory /lib/vendor/symfony/symfony-1.3.8/data/web/sf> # Alias /sf /lib/vendor/symfony/symfony-1.4.19/data/web/sf # <Directory /lib/vendor/symfony/symfony-1.4.19/data/web/sf> Options -Indexes -Includes AllowOverride All Allow from All </Directory> </VirtualHost> Can anyone spot what I may be doing wrong?. The site foobar.org does exist so I don't know why this error occurs - help?

• Java issues on OpenVZ Ubuntu 11.04 (.jar/.sh files)

  - by IWillNotChange

  I've had a whole line of messes with java and .jar files. I've tried both OpenJDK (from software installer) and about three repositories for Sun. /Desktop# java -jar -Xmx1024m ss.jar Exception in thread "main" java.awt.HeadlessException at java.awt.GraphicsEnvironment.checkHeadless(GraphicsEnvironment.java:173) at java.awt.Window.<init>(Window.java:476) at java.awt.Frame.<init>(Frame.java:419) at java.awt.Frame.<init>(Frame.java:384) at javax.swing.JFrame.<init>(JFrame.java:174) at org.powerbot.bd.<init>(Unknown Source) at org.powerbot.Boot.main(Unknown Source) Two separate errors: ~/Desktop# ./ss.sh [SEVERE] org.server.Boot: Default heap size of 490m too small, restarting with 768m and about 30 different crashes were it just "aborts" with a huge file dump. Each time I've tried something a little different, whether it be updating Java or just changing -Xmx1024 to -Xmx1024m to get rid of the heap. Personally I think it has something to do with OpenVZ, but Google hasn't saved me this time, I need someone who can get to the bottom of my problem. java -version java version "1.6.0_26" Java(TM) SE Runtime Environment (build 1.6.0_26-b03) Java HotSpot(TM) 64-Bit Server VM (build 20.1-b02, mixed mode) is my current install. Running ss.sh gives me: (I'd post the entire log but its long) # # A fatal error has been detected by the Java Runtime Environment: # # SIGILL (0x4) at pc=0x00002b14278e6fa0, pid=9301, tid=47365590714112 # # JRE version: 6.0_26-b03 # Java VM: Java HotSpot(TM) 64-Bit Server VM (20.1-b02 mixed mode linux-amd64 compressed oops) # Problematic frame: # C [ld-linux-x86-64.so.2+0x14fa0] _dl_make_stack_executable+0x2b50 # # If you would like to submit a bug report, please visit: # http://java.sun.com/webapps/bugreport/crash.jsp # The crash happened outside the Java Virtual Machine in native code. # See problematic frame for where to report the bug. # I'm willing to let someone who knows what they are talking about view it and try and sort this out. Any help would be appreciated, I've about pulled all my hair Googling to no avail.
