  • Consuming PHP webservice with .Net C#, error with array

    - by Faber
    I've a problem calling a PHP Web Service from .Net application. This is the XML response and I think there is a problem with the return node <?xml version="1.0" encoding="ISO-8859-1"?> <SOAP-ENV:Envelope SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/"> <SOAP-ENV:Body> <ns1:infoprodottoResponse xmlns:ns1="http://wan3.edc.it"> <result xsi:type="SOAP-ENC:Array" SOAP-ENC:arrayType=":[0]"></result> <error xsi:type="xsd:string">8u9lvDe3RBiGuXyL9lvM2tODlRMtcN77ya3S2LDEWEetBeRz/k4mXkK4hSqpgZOKilHYXgycj6Jtu8iBTfR1FQ==</error> <token xsi:type="xsd:string">5o58H00T96AWedhG1tnSc4xR+yXg7PQfQzXYVpri2AY=</token> </ns1:infoprodottoResponse> </SOAP-ENV:Body> In result node the SOAP-ENC:arrayType attribute hasn't declared the array type. The array type must be declare if the SOAP-ENC:arrayType is present, isn't it? It must be declared also if the array is empty?

  • How do I fix "java.lang.OutOfMemoryError at sun.misc.Unsafe.allocateMemory(Native Method)"?

    - by Jephir
    I'm making a Java application that uses the Slick library to load images. However, on some computers, I get this error when trying to run the program: Exception in thread "main" java.lang.OutOfMemoryError at sun.misc.Unsafe.allocateMemory(Native Method) at java.nio.DirectByteBuffer.<init>(DirectByteBuffer.java:99) at java.nio.ByteBuffer.allocateDirect(ByteBuffer.java:288) at org.lwjgl.BufferUtils.createByteBuffer(BufferUtils.java:60) at org.newdawn.slick.opengl.PNGImageData.loadImage(PNGImageData.java:692) at org.newdawn.slick.opengl.CompositeImageData.loadImage(CompositeImageData.java:62) at org.newdawn.slick.opengl.CompositeImageData.loadImage(CompositeImageData.java:43) My VM options are: -Djava.library.path=lib -Xms1024M -Xmx1024M -XX:PermSize=256M -XX:MaxPermSize=256M The program loads a few large images (1024 x 768 resolution) at the beginning. Any help to solve this problem would be greatly appreciated.

  • 0.20.2 API hadoop version with java 5

    - by abdeslam
    I have started a maven project trying to implement the MapReduce algorithm in java 1.5.0_14. I have chosen the 0.20.2 API hadoop version. In the pom.xml i'm using thus the following dependency: < dependency < groupId>org.apache.hadoop< /groupId> < artifactId>hadoop-core< /artifactId> < version>0.20.2< /version> < /dependency But when I'm using an import to the org.apache.hadoop classes, I get the following error: bad class file: ${HOME_DIR}\repository\org\apache\hadoop\hadoop-core\0.20.2\hadoop-core-0.20.2.jar(org/apache/hadoop/fs/Path.class) class file has wrong version 50.0, should be 49.0. Does someone know how can I solve this issue. Thanks.

  • Workaround for UnsupportedAudioFileException ?

    - by tschan
    I'm in a very early stage of writing a small music/rhythm game in Java (via Slick framework, which in turns uses OpenAL, but that's probably irrelevant here). The game needs to read (and playback) several sound files in WAV format, but some of the files are throwing [javax.sound.sampled.UnsupportedAudioFileException] exceptions. at javax.sound.sampled.AudioSystem.getAudioInputStream(AudioSystem.java:1102) at org.newdawn.slick.openal.WaveData.create(WaveData.java:123) at org.newdawn.slick.openal.SoundStore.getWAV(SoundStore.java:713) at org.newdawn.slick.openal.SoundStore.getWAV(SoundStore.java:683) at org.newdawn.slick.Sound.<init>(Sound.java:33) The files can be played back just fine in Winamp or Foobar2000, so this means Java just don't recognize some variants of the file format. What are my options at this point? Note: The files in question are user-supplied, so i cannot just convert them beforehand (using something like audacity). Any conversion steps must be done at runtime.

  • Struts2 Hibernate Login with User table and group table

    - by J2ME NewBiew
    My problem is, i have a table User and Table Group (this table use to authorization for user - it mean when user belong to a group like admin, they can login into admincp and other user belong to group member, they just only read and write and can not login into admincp) each user maybe belong to many groups and each group has been contain many users and they have relationship are many to many I use hibernate for persistence storage. and struts 2 to handle business logic. When i want to implement login action from Struts2 how can i get value of group member belong to ? to compare with value i want to know? Example I get user from username and password then get group from user class but i dont know how to get value of group user belong to it mean if user belong to Groupid is 1 and in group table , at column adminpermission is 1, that user can login into admincp, otherwise he can't my code: User.java /* * To change this template, choose Tools | Templates * and open the template in the editor. */ package org.dejavu.software.model;

  • Domain validates but won't save

    - by marko
    I have the following setup. Class, say, Car that has a CarPart (belongsTo=[car:Car]). When I'm creating a Car I also want to create som default CarParts, so I do def car = new Car(bla bla bla) def part = new CarPart(car:car) Now, when I do car.validate() or part.validate() it seems fine.

  • Need help with writing from XML to a SQL Server database (detailed)

    - by fogedi
    I'm a bit of a newbie with XML and WebServices and stuff like that. I'm working on a project using GlassFish OpenESB to schedule a process to get some information from a webservice and then store in a database. The criteria is basically that i have to use GlassFish OpenESB or EJB modules where i can expose webservices or something along those lines, AND i have to use SQL Server 2005. So far I've been able to talk to the webservice: and receive something along those lines <?xml version="1.0" encoding="UTF-8" standalone="no"?> <SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://schemas.xmlsoap.org/soap/envelope/ http://schemas.xmlsoap.org/soap/envelope/"> <SOAP-ENV:Body> <m:entrypoint_getSettlementsOperationResponse xmlns:m="http://j2ee.netbeans.org/wsdl/BorgunTestBPEL/entrypoint_getSettlements"> <part1> <GetSettlementsByMerchantResponse xmlns="http://Borgun.Services.Gateway/2010/04/Settlement"> <GetSettlementsByMerchantResult xmlns:a="http://schemas.datacontract.org/2004/07/Borgun.Library.Common" xmlns:i="http://www.w3.org/2001/XMLSchema-instance" xmlns:msgns="http://Borgun.Services.Gateway/2010/04/Settlement" xmlns:ns0="http://j2ee.netbeans.org/wsdl/BorgunTestBPEL/entrypoint_getSettlements"> <a:CreditCardSettlement> <a:amexAmount>XXX</a:amexAmount> <a:amount>XXXX</a:amount> <a:batches> <a:CreditCardBatch> <a:batchdate>xxx</a:batchdate> <a:batchnumber>XXXX</a:batchnumber> <a:currencyCode>xxxx</a:currencyCode> <a:merchantnumber>xxxx</a:merchantnumber> <a:settlementRunNumber>xx4</a:settlementRunNumber> <a:settlementdate>2010-04-06T00:00:00</a:settlementdate> <a:slips>2</a:slips> <a:sum>xxxx</a:sum> </a:CreditCardBatch> <a:CreditCardBatch> <a:batchdate>xxx</a:batchdate> <a:batchnumber>xxxxx</a:batchnumber> <a:currencyCode>xxxx</a:currencyCode> <a:merchantnumber>xxxx</a:merchantnumber> <a:settlementRunNumber>xxxx</a:settlementRunNumber> <a:settlementdate>xxxx</a:settlementdate> <a:slips>x</a:slips> <a:sum>xxx</a:sum> </a:CreditCardBatch> </a:batches> <a:commission>xx</a:commission> <a:currencyCode>xxx</a:currencyCode> <a:deduction>-xxx</a:deduction> <a:deductionItems> <a:CrediCardSettlementDeduction> <a:amount>-xxx</a:amount> <a:code>VIÐSKF</a:code> <a:currencyCode>ISK</a:currencyCode> <a:merchantnumber>xxx</a:merchantnumber> <a:settlementrunnumber>xxx</a:settlementrunnumber> <a:text>Afsláttur v/ekorta</a:text> </a:CrediCardSettlementDeduction> <a:CrediCardSettlementDeduction> <a:amount>-335.00</a:amount> <a:code>ÁLAGKREK</a:code> <a:currencyCode>ISK</a:currencyCode> <a:merchantnumber>xxx</a:merchantnumber> <a:settlementrunnumber>xxx</a:settlementrunnumber> <a:text>xxx</a:text> </a:CrediCardSettlementDeduction> </a:deductionItems> </a:CreditCardSettlement> </GetSettlementsByMerchantResult> </GetSettlementsByMerchantResponse> </part1> </m:entrypoint_getSettlementsOperationResponse> </SOAP-ENV:Body> </SOAP-ENV:Envelope> I have access to the SQL Server 2005 server which is remote and i know i can insert into it but given that now i have a one-to-many relationship i want to be able to rollback if something fails. So in short how can I insert from this XML into the DB preferably without manually walking through the XML tree? I'm pretty sure I'm supposed to be able to use Entity and Session Beans or maybe JAXB bindings but I'm simply not being successful. One of the reasons might have something to do with the fact that the soap response contains an array of CreditCardSettlements and each of which contains an array of Batches and DeductionItems It would be best if someone can help me do this via a BPEL in GlassFish OpenESB but any hint at a java solution is much appreciated.

  • SpringMvc java.lang.NullPointerException When Posting Form To Server

    - by dev_darin
    I have a form with a user name field on it when i tab out of the field i use a RESTFUL Web Service that makes a call to a handler method in the controller. The method makes a call to a DAO class that checks the database if the user name exists. This works fine, however when the form is posted to the server i call the same exact function i would call in the handler method however i get a java.lang.NullPointerException when it accesses the class that makes a call to the DAO object. So it does not even access the DAO object the second time. I have exception handlers around the calls in all my classes that makes calls. Any ideas as to whats happening here why i would get the java.lang.NullPointerException the second time the function is called.Does this have anything to do with Spring instantiating DAO classes using a Singleton method or something to that effect? What can be done to resolve this? This is what happens the First Time The Method is called using the Web Service(this is suppose to happen): 13011 [http-8084-2] INFO com.crimetrack.jdbc.JdbcOfficersDAO - Inside jdbcOfficersDAO 13031 [http-8084-2] DEBUG org.springframework.jdbc.core.JdbcTemplate - Executing prepared SQL query 13034 [http-8084-2] DEBUG org.springframework.jdbc.core.JdbcTemplate - Executing prepared SQL statement [SELECT userName FROM crimetrack.tblofficers WHERE userName = ?] 13071 [http-8084-2] DEBUG org.springframework.jdbc.datasource.DataSourceUtils - Fetching JDBC Connection from DataSource 13496 [http-8084-2] DEBUG org.springframework.jdbc.core.StatementCreatorUtils - Setting SQL statement parameter value: column index 1, parameter value [adminz], value class [java.lang.String], SQL type unknown 13534 [http-8084-2] DEBUG org.springframework.jdbc.datasource.DataSourceUtils - Returning JDBC Connection to DataSource 13537 [http-8084-2] INFO com.crimetrack.jdbc.JdbcOfficersDAO - No username was found in exception 13537 [http-8084-2] INFO com.crimetrack.service.ValidateUserNameManager - UserName :adminz does NOT exist The Second time When The Form Is 'Post' and a validation method handles the form and calls the same method the web service would call: 17199 [http-8084-2] INFO com.crimetrack.service.OfficerRegistrationValidation - UserName is not null so going to check if its valid for :adminz 17199 [http-8084-2] INFO com.crimetrack.service.OfficerRegistrationValidation - User Name in try.....catch block is adminz 17199 [http-8084-2] INFO com.crimetrack.service.ValidateUserNameManager - Inside Do UserNameExist about to validate with username : adminz 17199 [http-8084-2] INFO com.crimetrack.service.ValidateUserNameManager - UserName :adminz EXCEPTION OCCURED java.lang.NullPointerException

  • Netbeans, JPA Entity Beans in seperate projects. Unknown entity bean class

    - by Stu
    I am working in Netbeans and have my entity beans and web services in separate projects. I include the entity beans in the web services project however the ApplicaitonConfig.java file keeps getting over written and removing the entries I make for the entity beans in the associated jar file. My question is: is it required to have both the EntityBeans and the WebServices share the same project/jar file? If not what is the appropriate way to include the entity beans which are in the jar file? <?xml version="1.0" encoding="UTF-8"?> <persistence version="2.1" xmlns="http://xmlns.jcp.org/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/persistence http://xmlns.jcp.org/xml/ns/persistence/persistence_2_1.xsd"> <persistence-unit name="jdbc/emrPool" transaction-type="JTA"> <provider>org.eclipse.persistence.jpa.PersistenceProvider</provider> <jta-data-source>jdbc/emrPool</jta-data-source> <exclude-unlisted-classes>false</exclude-unlisted-classes> <properties> <property name="eclipselink.ddl-generation" value="none"/> <property name="eclipselink.cache.shared.default" value="false"/> </properties> </persistence-unit> </persistence> Based on Melc's input i verified that that the transaction type is set to JTA and the jta-data-source is set to the value for the Glassfish JDBC Resource. Unfortunately the problem still persists. I have opened the WAR file and validated that the EntityBean.jar file is the latest version and is located in the WEB-INF/lib directory of the War file. I think it is tied to the fact that the entities are not being "registered" with the entity manager. However i do not know why they are not being registered.

  • How do I control output files name and content of an Hadoop streaming job?

    - by Eran Kampf
    Is there a way to control the output filenames of an Hadoop Streaming job? Specifically I would like my job's output files content and name to be organized by the ket the reducer outputs - each file would only contain values for one key and its name would be the key. Update: Just found the answer - Using a Java class that derives from MultipleOutputFormat as the jobs output format allows control of the output file names. http://hadoop.apache.org/core/docs/current/api/org/apache/hadoop/mapred/lib/MultipleOutputFormat.htmlhttp://hadoop.apache.org/core/docs/current/api/org/apache/hadoop/mapred/lib/MultipleOutputFormat.html I havent seen any samples for this out there... Can anyone point out to an Hadoop Streaming sample that makes use of a custom output format Java class?

  • Spring OpenSessionInViewFilter with @Transactional annotation

    - by Gautam
    This is regarding Spring OpenSessionInViewFilter using with @Transactional annotation at service layer. i went through so many stack overflow post on this but still confused about whether i should use OpenSessionInViewFilter or not to avoid LazyInitializationException It would be great help if somebody help me find out answer to below queries. Is it bad practice to use OpenSessionInViewFilter in application having complex schema. using this filter can cause N+1 problem if we are using OpenSessionInViewFilter does it mean @Transactional not required? Below is my Spring config file <context:component-scan base-package="com.test"/> <context:annotation-config/> <bean id="messageSource" class="org.springframework.context.support.ReloadableResourceBundleMessageSource"> <property name="basename" value="resources/messages" /> <property name="defaultEncoding" value="UTF-8" /> </bean> <bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer" p:location="/WEB-INF/jdbc.properties" /> <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close" p:driverClassName="${jdbc.driverClassName}" p:url="${jdbc.databaseurl}" p:username="${jdbc.username}" p:password="${jdbc.password}" /> <bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean"> <property name="dataSource" ref="dataSource" /> <property name="configLocation"> <value>classpath:hibernate.cfg.xml</value> </property> <property name="configurationClass"> <value>org.hibernate.cfg.AnnotationConfiguration</value> </property> <property name="hibernateProperties"> <props> <prop key="hibernate.dialect">${jdbc.dialect}</prop> <prop key="hibernate.show_sql">true</prop> <!-- <prop key="hibernate.hbm2ddl.auto">create</prop> --> </props> </property> </bean> <tx:annotation-driven /> <bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager"> <property name="sessionFactory" ref="sessionFactory" /> </bean>

  • Tomcat thread waiting on and locking the same resource

    - by Adam Matan
    Consider the following Java\Tomcat thread dump: "http-0.0.0.0-4080-4" daemon prio=10 tid=0x0000000019a2b000 nid=0x360e in Object.wait() [0x0000000040b71000] java.lang.Thread.State: WAITING (on object monitor) at java.lang.Object.wait(Native Method) - waiting on <0x00002ab5565fe358> (a org.apache.tomcat.util.net.JIoEndpoint$Worker) at java.lang.Object.wait(Object.java:485) at org.apache.tomcat.util.net.JIoEndpoint$Worker.await(JIoEndpoint.java:458) - locked <0x00002ab5565fe358> (a org.apache.tomcat.util.net.JIoEndpoint$Worker) at org.apache.tomcat.util.net.JIoEndpoint$Worker.run(JIoEndpoint.java:484) at java.lang.Thread.run(Thread.java:662) Is this a deadlock? It seems that the same resource (0x00002ab5565fe358) is both locked and waited on - what does it mean?

  • Passing URIs as URL arguments in Drupal 6

    - by wynz
    I'm running into problems trying to pass absolute URIs as parameters with clean URLs enabled. I've got hook_menu() set up like this: function mymodule_menu() { return array( 'page/%' = array( 'title' = 'DBpedia Display Test', 'page callback' = 'mymodule_dbpedia_display', 'page arguments' = array(1), ), ); } and in the page callback: function mymodule_dbpedia_display($uri) { // Make an HTTP request for this URI // and then render some things return $output; } What I'm hoping to do is somehow pass full URIs (e.g. "http://dbpedia.org/resource/Coffee") to my page callback. I've tried a few things and nothing's worked so far... http://mysite.com/page/http%3A%2F%2Fdbpedia.org%2Fresource%2FCoffee Completely breaks Drupal's rewriting http://mysite.com/page/?uri=http%3A%2F%2Fdbpedia.org%2Fresource%2FCoffee Gives a 404 http://mysite.com/page/http://dbpedia.org/resource/Coffee Returns just "http:", which makes sense I could probably use $_GET to pull out the whole query string, but I guess I'm hoping for a more 'Drupal' solution. Any suggestions?

  • Using AsyncTask, but experiencing unexpected behaviour

    - by capcom
    Please refer to the following code which continuously calls a new AsyncTask. The purpose of the AsyncTask is to make an HTTP request, and update the string result. package room.temperature; import java.io.BufferedReader; import java.io.InputStream; import java.io.InputStreamReader; import java.util.ArrayList; import java.util.concurrent.ExecutionException; import org.apache.http.HttpEntity; import org.apache.http.HttpResponse; import org.apache.http.NameValuePair; import org.apache.http.client.HttpClient; import org.apache.http.client.entity.UrlEncodedFormEntity; import org.apache.http.client.methods.HttpPost; import org.apache.http.impl.client.DefaultHttpClient; import android.app.Activity; import android.os.AsyncTask; import android.os.Bundle; import android.util.Log; import android.widget.TextView; public class RoomTemperatureActivity extends Activity { String result = null; StringBuilder sb=null; TextView TemperatureText, DateText; ArrayList<NameValuePair> nameValuePairs; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); TemperatureText = (TextView) findViewById(R.id.temperature); DateText = (TextView) findViewById(R.id.date); nameValuePairs = new ArrayList<NameValuePair>(); for (int i = 0; i < 10; i++) { RefreshValuesTask task = new RefreshValuesTask(); task.execute(""); } } // The definition of our task class private class RefreshValuesTask extends AsyncTask<String, Integer, String> { @Override protected void onPreExecute() { super.onPreExecute(); } @Override protected String doInBackground(String... params) { InputStream is = null; try { HttpClient httpclient = new DefaultHttpClient(); HttpPost httppost = new HttpPost("http://mywebsite.com/roomtemp/tempscript.php"); httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs)); HttpResponse response = httpclient.execute(httppost); HttpEntity entity = response.getEntity(); is = entity.getContent(); } catch(Exception e) { Log.e("log_tag", "Error in http connection" + e.toString()); } try { BufferedReader reader = new BufferedReader(new InputStreamReader(is,"iso-8859-1"),8); sb = new StringBuilder(); sb.append(reader.readLine()); is.close(); result=sb.toString(); } catch(Exception e) { Log.e("log_tag", "Error converting result " + e.toString()); } return result; } @Override protected void onProgressUpdate(Integer... values) { super.onProgressUpdate(values); } @Override protected void onPostExecute(String result) { super.onPostExecute(result); //System.out.println(result); setValues(result); } } public void setValues(String resultValue) { System.out.println(resultValue); String[] values = resultValue.split("&"); TemperatureText.setText(values[0]); DateText.setText(values[1]); } } The problem I am experiencing relates to the AsyncTask in some way or the function setValues(), but I am not sure how. Essentially, I want each call to the AsyncTask to run, eventually in an infinite while loop, and update the TextView fields as I have attempted in setValues. I have tried since yesterday after asking a question which led to this code, for reference. Oh yes, I did try using the AsyncTask get() method, but that didn't work either as I found out that it is actually a synchronous call, and renders the whole point of AsyncTask useless.

  • What is the 'accumulator in HQ9+?

    - by Koning Baard XIV
    I was just reading a bit about the HQ9+ programming language ( http://esolangs.org/wiki/HQ9 , http://en.wikipedia.org/wiki/HQ9%2B and http://www.cliff.biffle.org/esoterica/hq9plus.html ), and it tells me something about a so called 'accumulator' which can be incremented, but not be accessed. Also, using the + doesn't manipulate the result: code H+H result Hello World Hello World Can anyone explain me how this works, what this does and if it even makes any sense? Thanks

  • Configuring Jenkins for running with BitBucket

    - by Claus
    I'm trying to setup Jenkins on my mac mini in order to pull my iOS project source code from BitBucket and build it automatically. I've already gone through the major well know problems generating the ssh keys,uploading them in BitBucket,performing an ssh connection by console for adding the host to the well know list (you can find all my adventure here and here). Now,there are 3 user in my system: A,B and Shared. When I installed Jenkins it automatically placed itself in Shared, but I generated the ssh keys with the user A. So just to be clear In the A home directory there is an .ssh directory with public and private keys. When I try to run by Jenkins job I get this error message: Started by user anonymous Building in workspace /Users/Shared/Jenkins/Home/jobs/myprojectAdHocBuild/workspace Checkout:workspace / /Users/Shared/Jenkins/Home/jobs/myprojectAdHocBuild/workspace - hudson.remoting.LocalChannel@625cb0bb Using strategy: Default Cloning the remote Git repository Cloning repository [email protected]:myuser/myproject.git git --version git version 1.8.0 ERROR: Error cloning remote repo 'origin' : Could not clone [email protected]:myuser/myproject.git hudson.plugins.git.GitException: Could not clone [email protected]:myuser/myproject.git at hudson.plugins.git.GitAPI.clone(GitAPI.java:271) at hudson.plugins.git.GitSCM$2.invoke(GitSCM.java:1036) at hudson.plugins.git.GitSCM$2.invoke(GitSCM.java:978) at hudson.FilePath.act(FilePath.java:851) at hudson.FilePath.act(FilePath.java:824) at hudson.plugins.git.GitSCM.determineRevisionToBuild(GitSCM.java:978) at hudson.plugins.git.GitSCM.checkout(GitSCM.java:1134) at hudson.model.AbstractProject.checkout(AbstractProject.java:1325) at hudson.model.AbstractBuild$AbstractBuildExecution.defaultCheckout(AbstractBuild.java:676) at jenkins.scm.SCMCheckoutStrategy.checkout(SCMCheckoutStrategy.java:88) at hudson.model.AbstractBuild$AbstractBuildExecution.run(AbstractBuild.java:581) at hudson.model.Run.execute(Run.java:1516) at hudson.model.FreeStyleBuild.run(FreeStyleBuild.java:46) at hudson.model.ResourceController.execute(ResourceController.java:88) at hudson.model.Executor.run(Executor.java:236) Caused by: hudson.plugins.git.GitException: Command "/usr/local/git/bin/git clone --progress -o origin [email protected]:myuser/myproject.git /Users/Shared/Jenkins/Home/jobs/myprojectAdHocBuild/workspace" returned status code 128: stdout: Cloning into '/Users/Shared/Jenkins/Home/jobs/myprojectAdHocBuild/workspace'... stderr: Host key verification failed. fatal: Could not read from remote repository.

It looks like Jenkins is trying to run a command with a user which doesn't have permission to retrieve the appropriate keys from my .ssh directory.Not really sure.Maybe this output can help: MacMini:~ myuser$ ps axu | grep "/jenkins" myuser 11660 0.0 4.6 2918124 97096 ??

  • Failed upgrade of PHP on Ubunutu 12.04, error: Sub-process /usr/bin/dpkg returned an error code (1)
