• Grails + GAE - Issue using app.servlet.version=2.5

  - by Taylor L

  Updating the servlet version in application.properties to 2.5 has no affect on the generated web.xml. The generated web.xml is still version 2.4. app.servlet.version=2.5 Also, if I try to execute "run-app" I get the exception below: Running Grails application..

• Possible to programatically access X-Mms-Content-Location?

  - by Brad Hein

  Is it possible to access the X-Mms-Content-Location attribute of a message from a MMS message programatically, using the Android SDK? This is one example of the error that I am investigating. If I can access that attribute, then I may be able to code an app which repairs it so the message retrieval succeeds. 04-26 19:11:35.573 V/RetrieveTransaction( 299): X-Mms-Content-Location: http://69.78.70..70/servlets/mms?message-id=<GUID_REMOVED_FOR_PRIVACY> <snip> 04-26 19:11:35.783 I/InetAddress( 299): Unknown host 69.78.70..70, throwing UnknownHostException 04-26 19:11:35.793 V/RetrieveTransaction( 299): Unexpected IOException. 04-26 19:11:35.793 V/RetrieveTransaction( 299): java.io.IOException: Cannot establish route for http://69.78.70..70/servlets/mms?message-id=<GUID_REMOVED_FOR_PRIVACY>: Unknown host 04-26 19:11:35.793 V/RetrieveTransaction( 299): at com.android.mms.transaction.Transaction.ensureRouteToHost(Transaction.java:206) 04-26 19:11:35.793 V/RetrieveTransaction( 299): at com.android.mms.transaction.Transaction.getPdu(Transaction.java:171) 04-26 19:11:35.793 V/RetrieveTransaction( 299): at com.android.mms.transaction.RetrieveTransaction.run(RetrieveTransaction.java:147) 04-26 19:11:35.793 V/RetrieveTransaction( 299): at java.lang.Thread.run(Thread.java:1058) 04-26 19:11:35.793 E/RetrieveTransaction( 299): Retrieval failed.

• ejb lookup failing with NamingException

• Replacing a Namespace with XSLT

  - by er4z0r

  Hi I want to work around a 'bug' in certain RSS-feeds, which use an incorrect namespace for the mediaRSS module. I tried to do it by manipulating the DOM programmatically, but using XSLT seems more flexible to me. Example: <media:thumbnail xmlns:media="http://search.yahoo.com/mrss" url="http://www.suedkurier.de/storage/pic/dpa/infoline/brennpunkte/4311018_0_merkelxI_24280028_original.large-4-3-800-199-0-3131-2202.jpg" /> <media:thumbnail url="http://www.suedkurier.de/storage/pic/dpa/infoline/brennpunkte/4311018_0_merkelxI_24280028_original.large-4-3-800-199-0-3131-2202.jpg" /> Where the namespace must be http://search.yahoo.com/mrss/ (mind the slash). This is my stylesheet: <?xml version="1.0" encoding="UTF-8"?> <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <xsl:template match="//*[namespace-uri()='http://search.yahoo.com/mrss']"> <xsl:element name="{local-name()}" namespace="http://search.yahoo.com/mrss/" > <xsl:apply-templates select="@*|*|text()" /> </xsl:element> </xsl:template> </xsl:stylesheet> Unfortunately the result of the transformation is an invalid XML and my RSS-Parser (ROME Library) does not parse the feed anymore: java.lang.IllegalStateException: Root element not set at org.jdom.Document.getRootElement(Document.java:218) at com.sun.syndication.io.impl.RSS090Parser.isMyType(RSS090Parser.java:58) at com.sun.syndication.io.impl.FeedParsers.getParserFor(FeedParsers.java:72) at com.sun.syndication.io.WireFeedInput.build(WireFeedInput.java:273) at com.sun.syndication.io.WireFeedInput.build(WireFeedInput.java:251) ... 8 more What is wrong with my stylesheet?

• How to load static files from view HTML in web2py?

  - by MikeWyatt

  Given a view with layout, how can I load static files (CSS and JS, essentially) into the <head> from the view file? layout.html <!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" xml:lang="{{=T.accepted_language or 'en'}}"> <head> <title>{{=response.title or request.application}}</title> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" /> <!-- include requires CSS files {{response.files.append(URL(request.application,'static','base.css'))}} {{response.files.append(URL(request.application,'static','ez-plug-min.css'))}} --> {{include 'web2py_ajax.html'}} </head> <body> {{include}} </body> </html> myview.html {{extend 'layout.html'}} {{response.files.append(URL(r=request,c='static',f='myview.css'))}} <h1>Some header</h1> <div> some content </div> In the above example, the "myview.css" file is either ignored by web2py or stripped out by the browser. So what is the best way to load page-specific files like this CSS file? I'd rather not stuff all my static files into my layout.

• Problem with apostrophes and other special characters when using aspell in windows

  - by Loftx

  Hi there, We seem to be having a problem with the spell checker on our content management system where it marks the ve part of We’ve as a misspelling. The spellchecker uses aspell which is called from a script on the server which executes the cmd.exe and uses it to pipe a file into aspell (it's a long winded way I know, but our server side programming langauge (ColdFusion) doesn't support writing to stdin for executables). Aspell is called by executing: c:\windows\system32\cmd.exe /c type d:\path_to_file\file.txt | "C:\Program Files\Aspell\bin\aspell" --lang=en -a Where file.txt contains the text to be spelled e.g. ^Oh have We’ve (the carat is added to prevent piping problems I believe). Aspell then output: @(#) International Ispell Version 3.1.20 (but really Aspell 0.50.3) * * * & ve 62 12: vie, voe, V, v, veg, vet, Be, Ce, be, Ev, E, e, vex, VA, VI, Va, Vi, vi, we, VD, VF, VG, VJ, VP, VT, Vt, vb, vs, DE, De, Fe, GE, Ge, He, IE, Le, ME, Me, NE, Ne, OE, PE, Re, SE, Se, Te, Xe, he, me, re, ye, Ave, Eve, Ive, ave, eve, VAR, var, veer, vier, view, vow However, we have a dev site, with the same version of Aspell, and when the same file is used it outputs with no misspellings. Both servers are running Aspell 0.50.3 on Windows server 2003, but there could be other differences in configuration: @(#) International Ispell Version 3.1.20 (but really Aspell 0.50.3) I'm wondering if the problem is to do with the piping part of the process or something different in the Aspell configuration. Does anyone have any ideas? Cheers, Tom

• NullPointerException when installing the Android SDK on Mac OS X

  - by Feanor

  I'm installing the Android SDK on Mac OS X. Following the instructions on the Android Development site, I've downloaded the SDK and modified my .bash_profile to include the path. The next step is to use the Android SDK and AVD Manager to actually download the platforms. However, when I use the Manager to install the platforms, I get the following error in the Terminal. I've looked around for similar problems in the Eclipse and Android forums and haven't found anything yet. Is something else damaged in the environment and needs to be repaired? Any recommendations on where I should look? java.lang.NullPointerException at org.eclipse.swt.graphics.Device.getFontList(Unknown Source) at org.eclipse.jface.resource.FontRegistry.filterData(FontRegistry.java:456) at org.eclipse.jface.resource.FontRegistry.createFont(FontRegistry.java:490) at org.eclipse.jface.resource.FontRegistry.defaultFontRecord(FontRegistry.java:551) at org.eclipse.jface.resource.FontRegistry.defaultFontData(FontRegistry.java:563) at org.eclipse.jface.resource.FontRegistry.getFontData(FontRegistry.java:579) at org.eclipse.jface.dialogs.Dialog.dialogFontIsDefault(Dialog.java:1077) at org.eclipse.jface.dialogs.Dialog.applyDialogFont(Dialog.java:998) at org.eclipse.jface.dialogs.Dialog.createContents(Dialog.java:756) at org.eclipse.jface.window.Window.create(Window.java:431) at org.eclipse.jface.dialogs.Dialog.create(Dialog.java:1089) at com.android.sdkuilib.internal.repository.UpdateChooserDialog.create(UpdateChooserDialog.java:280) at org.eclipse.jface.window.Window.open(Window.java:790) at com.android.sdkuilib.internal.repository.UpdaterData.updateOrInstallAll(UpdaterData.java:502) at com.android.sdkuilib.internal.repository.RemotePackagesPage.onInstallSelectedArchives(RemotePackagesPage.java:323) at com.android.sdkuilib.internal.repository.RemotePackagesPage.access$600(RemotePackagesPage.java:54) at com.android.sdkuilib.internal.repository.RemotePackagesPage$7.widgetSelected(RemotePackagesPage.java:168) at org.eclipse.swt.widgets.TypedListener.handleEvent(Unknown Source) at org.eclipse.swt.widgets.EventTable.sendEvent(Unknown Source) at org.eclipse.swt.widgets.Display.sendEvent(Unknown Source) at org.eclipse.swt.widgets.Widget.sendEvent(Unknown Source) at org.eclipse.swt.widgets.Widget.sendEvent(Unknown Source) at org.eclipse.swt.widgets.Widget.sendEvent(Unknown Source) at org.eclipse.swt.widgets.Widget.notifyListeners(Unknown Source) at org.eclipse.swt.widgets.Display.runDeferredEvents(Unknown Source) at org.eclipse.swt.widgets.Display.readAndDispatch(Unknown Source) at com.android.sdkuilib.internal.repository.UpdaterWindowImpl.open(UpdaterWindowImpl.java:104) at com.android.sdkuilib.repository.UpdaterWindow.open(UpdaterWindow.java:110) at com.android.sdkmanager.Main.showMainWindow(Main.java:281) at com.android.sdkmanager.Main.doAction(Main.java:247) at com.android.sdkmanager.Main.run(Main.java:92) at com.android.sdkmanager.Main.main(Main.java:81) logout

• Using HttpClient with SSL and certificates

  - by ChrisCM

  While I've been familiar with HTTPS and the concept of SSL, I have recently begun some development and found I am a little confused. The requirement was that I write a small Java application that runs on a machine attached to a scanner. When a document is scanned this is picked up and the file (usually PDF) sent over the internet to our application server that will then process it. I've written the application using Apache Commons libraries and HTTPClient. The second requirement was to connect over SSL, requiring a certificate. Following guidance on the HTTPclient page I am using AuthSSLProtocolSocketFactory from the contributions page. The constructor can take a keystore, keystore password, truststore and truststore password. As an initial test our DBA enabled SSL on one of our development webservers and provided me with a .p12 file which when I imported into IE allows me to connect successfully. I am a bit confused between keystores and truststores and what steps I need to take using the keytool. I tried importing the p12 into a keystore file but get the error: keytool error: java.lang.Exception: Input not an X.509 certificate I followed a suggestion of importing the p12 into Internet Explorer and exporting as a .cer which I can then successfully import into a keystore. When I supply this as a keystore argument of the AuthSSLProtocolSocketFactory I get a meaningless errror, but if I try it as a truststore it seems like it reads it fine but ultimately I get Caused by: javax.net.ssl.SSLHandshakeException: Received fatal alert: bad_certificate I am unsure if I have missed some steps, I am misunderstanding SSL and mutual authentication altogether or this is mis-configuration on the server side. Can anyone provide suggestions or point me towards resources that might help me figure this out please?

• jvm version for Websphere 6.1.0.23on Solaris

  - by dr jerry

  Hi I'm at big financial institute and we've an application running on Websphere 6.1. on Solaris. Due to MQ Connectivity we had to install fixpack 6.1.0.23. Unfortunately this broke an ejb (1.1) which is still there as legacy (Test missed it). [3/23/10 11:33:18:703 CET] 00000055 EJBContainerI E WSVR0068E: Attempt to start EnterpriseBean EventRisk_1.0.0#EventRiskEJB.jar#PolicyDataManager failed with exception: java.lang.NoSuchMethodError: com.ibm.ejs.csi.ResRefListImpl.(Lorg/eclipse/jst/j2ee/ejb/EnterpriseBean;Lcom/ibm/ejs/models/base/bindings/ejbbnd/EnterpriseBeanBinding;Lcom/ibm/ejs/models/base/extensions/ejbext/EnterpriseBeanExtension;)V at com.ibm.ws.metadata.ejb.EJBMDOrchestrator.finishBMDInit(EJBMDOrchestrator.java:1364) at com.ibm.ws.runtime.component.EJBContainerImpl.finishDeferredBeanMetaData(EJBContainerImpl.java:4829) at com.ibm.ws.runtime.component.EJBContainerImpl$3.run(EJBContainerImpl.java:4631) at java.security.AccessController.doPrivileged(Native Method) at com.ibm.ws.security.util.AccessController.doPrivileged(AccessController.java:125) at com.ibm.ws.runtime.component.EJBContainerImpl.initializeDeferredEJB(EJBContainerImpl.java:4627) at com.ibm.ejs.container.HomeOfHomes.getHome(HomeOfHomes.java:390) at com.ibm.ejs.container.HomeOfHomes.internalCreateWrapper(HomeOfHomes.java:938) at com.ibm.ejs.container.EJSContainer.createWrapper(EJSContainer.java:4783) at com.ibm.ejs.container.WrapperManager.faultOnKey(WrapperManager.java:545) at com.ibm.ejs.util.cache.Cache.findAndFault(Cache.java:498) at com.ibm.ejs.container.WrapperManager.keyToObject(WrapperManager.java:489) We cannot reproduce the issue on our desktop boxes (it all works fine there) and we do not have direct access to our the Solaris machines (dependent on the deployment department) we do suspect a discrepancy on the jvm but we're not sure. My question is two fold: can you confirm IBM's statement that fixpack 6.1.0.23 for solaris indeed runs on jvm 1.5.0_17b04 our installation tells us ./java -version java version "1.5.0_13" But deploy department is not eager to investigate. Do you see some other solution, apart from hiring big blue's con$ultancy? kind regards, Jeroen.

• JNI: Long-object created with wrong value

  - by Torbjörn Eklund

  Hi! I am writing a c-jni function in Android, and I am having problems with creating a Long-object. I have succeeded in calling the constructor, but when I read the value of the object with longValue, I get the wrong result. jmethodID longConstructor; jmethodID longGetLongValue; jclass cls; jobject obj; // Create a object of type Long. cls = (*env)->FindClass(env,"java/lang/Long"); longConstructor = (*env)->GetMethodID(env,cls,"<init>","(J)V"); obj = (*env)->NewObject(env, cls, longConstructor, 4242); // Get the value by calling the function longValue. longGetLongValue= (*env)->GetMethodID(env,cls,"longValue","()J"); long return_long_value = (*env)->CallLongMethod(env, obj, longGetLongValue); // Log the result. LOGD("%li", return_long_value); I would expect that the above code would print 4242 in the log, however the value that is printed in the log is 1691768. Does anybody have an idea on why 4242 is not written in the log?

• Problem using Hibernate Projections

  - by Lucas

  Hello! I'm using Richfaces + HibernateQuery to create a data list. I'm trying to use Hibernate Projections to group my query result. Here is the code: final DetachedCriteria criteria = DetachedCriteria .forClass(Class.class, "c") .setProjection(Projections.projectionList() .add(Projections.groupProperty("c.id"))); ... in the .xhtml file i have the following code: <rich:dataTable width="100%" id="dataTable" value="#{myBean.dataModel}" var="row"> <f:facet name="header"> <rich:columnGroup> ...... </rich:columnGroup> </f:facet> <h:column> <h:outputText value="#{row.id}"/> </h:column> <h:column> <h:outputText value="#{row.name}"/> </h:column> But when i run the page it gives me the following error: Error: value="#{row.id}": The class 'java.lang.Long' does not have the property 'id'. If i take out the Projection from the code it works correctly, but it doesn't group the result. So, which mistake could be happening here? EDIT: Here is the full criteria: final DetachedCriteria criteria = DetachedCriteria.forClass(Class.class, "c"); criteria.setFetchMode("e.zzzzz", FetchMode.JOIN); criteria.createAlias("e.aaaaaaaa", "aa"); criteria.add(Restrictions.ilike("aa.information", "informations....")); criteria.setProjection(Projections.distinct(Projections.projectionList() .add(Projections.groupProperty("e.id").as("e.id")))); getDao().findByCriteria(criteria); if i take the "setProjection" line it works fine. I don't understand why it gives that error putting that line.

• window.onload seems to trigger before the DOM is loaded (JavaScript)

  - by Dr. Monkey

  I am having trouble with the window.onload and document.onload events. Everything I read tells me these will not trigger until the DOM is fully loaded with all its resources, it seems like this isn't happening for me: I tried the following simple page in Chrome 4.1.249.1036 (41514) and IE 8.0.7600.16385 with the same result: both displayed the message "It failed!", indicating that myParagraph is not loaded (and so the DOM seems incomplete). <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en"> <head> <script type="text/javascript"> window.onload = doThis(); // document.onload gives the same result function doThis() { if (document.getElementById("myParagraph")) { alert("It worked!"); } else { alert("It failed!"); } } </script> </head> <body> <p id="myParagraph">Nothing is here.</p> </body> </html> I am using more complex scripts than this, in an external .js file, but this illustrates the problem. I can get it working by having window.onload set a timer for half a second to run doThis(), but this seems like an inelegant solution, and doesn't answer the question of why window.onload doesn't seem to do what everyone says it does. Another solution would be to set a timer that will check if the DOM is loaded, and if not it will just call itself half a second later (so it will keep checking until the DOM is loaded), but this seems overly complex to me. Is there a more appropriate event to use?

• Hudson: how do i use a parameterized build to do svn checkout and svn tag?

  - by Derick Bailey

  I'm setting up a parameterized build in hudson v1.362. the parameter i'm creting is used to determine which branch to checkout in subversion. I can set my svn repository url like this: https://my.svn.server/branches/${branch} and it does the checkout and the build just fine. now I want to tag the build after it finishes. i'm using the SVN tagging plugin for hudson to do this. so i go to the bottom of the project config screen for the hudson project and turn on "Perform Subversion tagging on successful build". here, i set my Tag Base URL to https://my.svn.server/tags/${branch}-${BUILD_NUMBER} and it gives me errors about those properties not being found. so i change them to environment variable usages like this: https://my.svn.server/tags/${env['branch']}-${env['BUILD_NUMBER']} and the svn tagging plugin is happy. the problem now is that my svn repository at the top is using the ${branch} syntax and the svn tagging plugin barfs on this: moduleLocation: Remote -https://my.svn.server/branches/$branch/ Tag Base URL: 'https://my.svn.server/tags/thebranchiused-1234'. There was no old tag at https://my.svn.server/tags/thebranchiused-1234. ERROR: Publisher hudson.plugins.svn_tag.SvnTagPublisher aborted due to exception java.lang.NullPointerException at hudson.plugins.svn_tag.SvnTagPlugin.perform(SvnTagPlugin.java:180) at hudson.plugins.svn_tag.SvnTagPublisher.perform(SvnTagPublisher.java:79) at hudson.tasks.BuildStepMonitor$3.perform(BuildStepMonitor.java:36) at hudson.model.AbstractBuild$AbstractRunner.perform(AbstractBuild.java:601) at hudson.model.AbstractBuild$AbstractRunner.performAllBuildSteps(AbstractBuild.java:580) at hudson.model.AbstractBuild$AbstractRunner.performAllBuildSteps(AbstractBuild.java:558) at hudson.model.Build$RunnerImpl.cleanUp(Build.java:167) at hudson.model.Run.run(Run.java:1295) at hudson.model.FreeStyleBuild.run(FreeStyleBuild.java:46) at hudson.model.ResourceController.execute(ResourceController.java:88) at hudson.model.Executor.run(Executor.java:124) Finished: FAILURE notice the first line, there: the svn tag is looking at ${branch} as part of the repository url... it's not parsing out the property value. i tried to change my original Repository URL for svn to use the ${env['branch']} syntax, but that blows up on the original checkout because this syntax is not getting parsed at all by the checkout. help?! how do i use a parameterized build to set the svn url for checkout and for tagging my build?!

• Running custom JAXB2 plugins using Maven JAXB 2.x Plugin

  - by nadouani

  I would like to generate JAXB Java classes using the Maven JAXB 2.x plugin http://static.highsource.org/mjiip/maven-jaxb2-plugin/generate-mojo.html To declare the custom JAXB plugins I would execute during the generate process, I used the "args" element like below: <plugin> <groupId>org.jvnet.jaxb2.maven2</groupId> <artifactId>maven-jaxb2-plugin</artifactId> <version>0.7.4</version> <executions> <execution> <goals> <goal>generate</goal> </goals> </execution> </executions> <configuration> <extension>true</extension> <args> <arg>-Xinheritance</arg> <arg>-XtoString</arg> </args> ... </configuration> ... </plugin> The issue is that the maven generate process is failing with the following error: Failed to execute goal org.jvnet.jaxb2.maven2:maven-jaxb2-plugin:0.7.4:generate (default) on project was: Error parsing the command line [[Ljava.lang.String;@1ad4a1ae] Any idea on how to specify the args values?

• Retrieving image from database using Ajax

  - by ama

  I'm trying to read image from database with Ajax, but I could not read the xmlhttp.responseText to the img src. The image is saved as binary data in database and also retrieved as binary data. I'm using Ajax in JSP, because I want to give the user the ability to upload images and I will view the last uploaded image, on mouse over action the Ajax will be activated and get the image back, the problem is in reading the img from the response. This is the Ajax function: function ajaxFunction(path) { if (xmlhttp) { var s = path; xmlhttp.open("GET", s, true); xmlhttp.onreadystatechange = handleServerResponse; xmlhttp.send(null); } } function handleServerResponse() { if (xmlhttp.readyState == 4) { var Image = document.getElementById(Image_Element_Name); document.getElementById(Image_Element_Name).src = "data:" + xmlhttp.responseText; } } I also got exception in the server: 10415315 [TP-Processor1] WARN core.MsgContext - Error sending end packet java.net.SocketException: Broken pipe at java.net.SocketOutputStream.socketWrite0(Native Method) at java.net.SocketOutputStream.socketWrite(SocketOutputStream.java:92) at java.net.SocketOutputStream.write(SocketOutputStream.java:136) at org.apache.jk.common.ChannelSocket.send(ChannelSocket.java:537) at org.apache.jk.common.JkInputStream.endMessage(JkInputStream.java:127) at org.apache.jk.core.MsgContext.action(MsgContext.java:302) at org.apache.coyote.Response.action(Response.java:183) at org.apache.coyote.Response.finish(Response.java:305) at org.apache.catalina.connector.OutputBuffer.close(OutputBuffer.java:281) at org.apache.catalina.connector.Response.finishResponse(Response.java:478) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:154) at org.apache.jk.server.JkCoyoteHandler.invoke(JkCoyoteHandler.java:200) at org.apache.jk.common.HandlerRequest.invoke(HandlerRequest.java:283) at org.apache.jk.common.ChannelSocket.invoke(ChannelSocket.java:773) at org.apache.jk.common.ChannelSocket.processConnection(ChannelSocket.java:703) at org.apache.jk.common.ChannelSocket$SocketConnection.runIt(ChannelSocket.java:895) at org.apache.tomcat.util.threads.ThreadPool$ControlRunnable.run(ThreadPool.java:685) at java.lang.Thread.run(Thread.java:619) 10415316 [TP-Processor1] WARN common.ChannelSocket - processCallbacks status 2

• Why can I run JUnit tests for my Spring project, but not a main method?

  - by FarmBoy

  I am using JDBC to connect to MySQL for a small application. In order to test without altering the real database, I'm using HSQL in memory for JUnit tests. I'm using Spring for DI and DAOs. Here is how I'm configuring my HSQL DataSource <bean id="mockDataSource" class="org.springframework.jdbc.datasource.SingleConnectionDataSource"> <property name="driverClassName" value="org.hsqldb.jdbcDriver"/> <property name="url" value="jdbc:hsqldb:mem:mockSeo"/> <property name="username" value="sa"/> </bean> This works fine for my JUnit tests which use the mock DB. But when I try to run a main method, I find the following error: Error creating bean with name 'mockDataSource' defined in class path resource [beans.xml]: Error setting property values; nested exception is org.springframework.beans.PropertyBatchUpdateException; nested PropertyAccessExceptions (1) are: PropertyAccessException 1: org.springframework.beans.MethodInvocationException: Property 'driverClassName' threw exception; nested exception is java.lang.IllegalStateException: Could not load JDBC driver class [org.hsqldb.jdbcDriver] I'm running from Eclipse, and I'm using the Maven plugin. Is there a reason why this would work as a Test, but not as a main()? I know that the main method itself is not the problem, because it works if I remove all references to the HSQL DataSource from my Spring Configuration file.

• Trouble with Berkeley DB JE Base API Secondary Databases and Sequences

  - by milosz

  I have a class Document which consists of Id (int) and Url (String). I would like to have a primary index on Id and secondary index on Url. I would also like to have a sequence for Id auto-incrementation. So I create a SecondaryDatabase and then I create a Sequence. During initialisation of the Sequence I get an exception: Exception in thread "main" java.lang.IllegalArgumentException at com.sleepycat.util.UtfOps.getCharLength(UtfOps.java:137) at com.sleepycat.util.UtfOps.bytesToString(UtfOps.java:259) at com.sleepycat.bind.tuple.TupleInput.readString(TupleInput.java:152) at pl.edu.mimuw.zbd.berkeley.zadanie.rozwiazanie.MyDocumentBiding.entryToObject(MyDocumentBiding.java:12) at pl.edu.mimuw.zbd.berkeley.zadanie.rozwiazanie.MyDocumentBiding.entryToObject(MyDocumentBiding.java:1) at com.sleepycat.bind.tuple.TupleBinding.entryToObject(TupleBinding.java:76) at pl.edu.mimuw.zbd.berkeley.zadanie.rozwiazanie.UrlKeyCreator.createSecondaryKey(UrlKeyCreator.java:20) at com.sleepycat.je.SecondaryDatabase.updateSecondary(SecondaryDatabase.java:835) at com.sleepycat.je.SecondaryTrigger.databaseUpdated(SecondaryTrigger.java:42) at com.sleepycat.je.Database.notifyTriggers(Database.java:2004) at com.sleepycat.je.Cursor.putNotify(Cursor.java:1692) at com.sleepycat.je.Cursor.putInternal(Cursor.java:1616) at com.sleepycat.je.Cursor.putNoOverwrite(Cursor.java:663) at com.sleepycat.je.Sequence.<init>(Sequence.java:188) at com.sleepycat.je.Database.openSequence(Database.java:546) at pl.edu.mimuw.zbd.berkeley.zadanie.rozwiazanie.MyFullTextSearchEngine.init(MyFullTextSearchEngine.java:131) at pl.edu.mimuw.zbd.berkeley.zadanie.testy.MyFullTextSearchEngineTest.main(MyFullTextSearchEngineTest.java:18) It seems that during the initialisation of the sequence the secondary database is forced to update. When I debug the entryToObject method of MyDocumentBiding the bytes that it tries to convert to object seem random. What am I doing wrong?

• "SessionId doesn't exist" error when starting Selenium server

  - by ripper234

  I'm raising a Selnium-server (the jar), and getting this exception without trying to talk to the server. What can be the cause? The errors keep coming in once every 2 seconds.

• Problem with copying local data onto HDFS on a Hadoop cluster using Amazon EC2/ S3.

  - by Deepak Konidena

  Hi, I have setup a Hadoop cluster containing 5 nodes on Amazon EC2. Now, when i login into the Master node and submit the following command bin/hadoop jar <program>.jar <arg1> <arg2> <path/to/input/file/on/S3> It throws the following errors (not at the same time.) The first error is thrown when i don't replace the slashes with '%2F' and the second is thrown when i replace them with '%2F': 1) Java.lang.IllegalArgumentException: Invalid hostname in URI S3://<ID>:<SECRETKEY>@<BUCKET>/<path-to-inputfile> 2) org.apache.hadoop.fs.S3.S3Exception: org.jets3t.service.S3ServiceException: S3 PUT failed for '/' XML Error Message: The request signature we calculated does not match the signature you provided. check your key and signing method. Note: 1)when i submitted jps to see what tasks were running on the Master, it just showed 1116 NameNode 1699 Jps 1180 JobTracker leaving DataNode and TaskTracker. 2)My Secret key contains two '/' (forward slashes). And i replace them with '%2F' in the S3 URI. PS: The program runs fine on EC2 when run on a single node. Its only when i launch a cluster, i run into issues related to copying data to/from S3 from/to HDFS. And, what does distcp do? Do i need to distribute the data even after i copy the data from S3 to HDFS?(I thought, HDFS took care of that internally) IF you could direct me to a link that explains running Map/reduce programs on a hadoop cluster using Amazon EC2/S3. That would be great. Regards, Deepak.
