• Advanced Experiments with JavaScript, CSS, HTML, JavaFX, and Java

  - by Geertjan

  Once you're embedding JavaScript, CSS, and HTML into your Java desktop application, via the JavaFX browser, a whole range of new possibilities open up to you. For example, here's an impressive page on-line, notice that you can drag items and drop them in new places: http://nettuts.s3.amazonaws.com/127_iNETTUTS/demo/index.html The source code of the above is provided too, so you can drop the various files directly into your NetBeans module and use the JavaFX WebEngine to load the HTML page into the JavaFX browser. Once the JavaFX browser is in a NetBeans TopComponent, you'll have the start of an off-line news composer, something like this: WebView view = new WebView(); view.setMinSize(widthDouble, heightDouble); view.setPrefSize(widthDouble, heightDouble); webengine = view.getEngine(); URL url = getClass().getResource("index.html"); webengine.load(url.toExternalForm()); webengine.getLoadWorker().stateProperty().addListener( new ChangeListener() { @Override public void changed(ObservableValue ov, State oldState, State newState) { if (newState == State.SUCCEEDED) { Document document = (Document) webengine.executeScript("document"); NodeList list = document.getElementById("columns").getChildNodes(); for (int i = 0; i < list.getLength(); i++) { EventTarget et = (EventTarget) list.item(i); et.addEventListener("click", new EventListener() { @Override public void handleEvent(Event evt) { instanceContent.add(new Date()); } }, true); } } } }); The above is the code showing how, whenever a news item is clicked, the current date can be published into the Lookup. As you can see, I have a viewer component listening to the Lookup for dates.

• At the Java DEMOgrounds - ZeroTurnaround and its LiveRebel 2.5

  - by Janice J. Heiss

  At the ZeroTurnaround demo, I spoke with Krishnan Badrinarayanan, their Product Marketing Manager. ZeroTurnaround, the creator of JRebel and LiveRebel, describes itself on their site as a company “dedicated to changing the way the world develops, tests and runs Java applications."“We just launched LiveRebel 2.5 today,” stated Badrinarayanan, “which enables companies to embrace the concept and practice of continuous delivery, which means having a pipeline that takes products right from the developers to an end-user, faster, more frequently -- all the while ensuring that it’s a quality product that does not break in production. So customers don’t feel the discontinuity that something has changed under them and that they can’t deal with the change. And all this happens while there is zero down time.”He pointed out that Salesforce.com is not useable from 3 a.m. to 5 a.m. on Saturday because they are engaged in maintenance. “With LiveRebel 2.5, you can unify the whole delivery chain without having any downtime at all,” he said. “There are many products that tell customers to take their tools and change how they work as an organization so that you they have to conform to the way the tool prescribes them to work as an application team. We take a more pragmatic approach. A lot of companies might use Jenkins or Bamboo to do continuous integration. We extend that. We say, take our product, take LiveRebel okay, and integrate it with Jenkins – you can do that quickly, so that, in half a day, you will be up and running. And let LiveRebel automate your deployment processes and all the automated tasks that go with it. Right from tests to the staging environment to production -- all with zero downtime and with no impact on users currently using the system.” “So if you were to make the update right now and you had 100 users on your system, they would not even know this was happening. It would maintain their sessions and transfer them over to the new version, all in the background.”

• What is the fastest cyclic synchronization in Java (ExecutorService vs. CyclicBarrier vs. X)?

  - by Alex Dunlop

  Which Java synchronization construct is likely to provide the best performance for a concurrent, iterative processing scenario with a fixed number of threads like the one outlined below? After experimenting on my own for a while (using ExecutorService and CyclicBarrier) and being somewhat surprised by the results, I would be grateful for some expert advice and maybe some new ideas. Existing questions here do not seem to focus primarily on performance, hence this new one. Thanks in advance! The core of the app is a simple iterative data processing algorithm, parallelized to the spread the computational load across 8 cores on a Mac Pro, running OS X 10.6 and Java 1.6.0_07. The data to be processed is split into 8 blocks and each block is fed to a Runnable to be executed by one of a fixed number of threads. Parallelizing the algorithm was fairly straightforward, and it functionally works as desired, but its performance is not yet what I think it could be. The app seems to spend a lot of time in system calls synchronizing, so after some profiling I wonder whether I selected the most appropriate synchronization mechanism(s). A key requirement of the algorithm is that it needs to proceed in stages, so the threads need to sync up at the end of each stage. The main thread prepares the work (very low overhead), passes it to the threads, lets them work on it, then proceeds when all threads are done, rearranges the work (again very low overhead) and repeats the cycle. The machine is dedicated to this task, Garbage Collection is minimized by using per-thread pools of pre-allocated items, and the number of threads can be fixed (no incoming requests or the like, just one thread per CPU core). V1 - ExecutorService My first implementation used an ExecutorService with 8 worker threads. The program creates 8 tasks holding the work and then lets them work on it, roughly like this: // create one thread per CPU executorService = Executors.newFixedThreadPool( 8 ); ... // now process data in cycles while( ...) { // package data into 8 work items ... // create one Callable task per work item ... // submit the Callables to the worker threads executorService.invokeAll( taskList ); } This works well functionally (it does what it should), and for very large work items indeed all 8 CPUs become highly loaded, as much as the processing algorithm would be expected to allow (some work items will finish faster than others, then idle). However, as the work items become smaller (and this is not really under the program's control), the user CPU load shrinks dramatically: blocksize | system | user | cycles/sec 256k 1.8% 85% 1.30 64k 2.5% 77% 5.6 16k 4% 64% 22.5 4096 8% 56% 86 1024 13% 38% 227 256 17% 19% 420 64 19% 17% 948 16 19% 13% 1626 Legend: - block size = size of the work item (= computational steps) - system = system load, as shown in OS X Activity Monitor (red bar) - user = user load, as shown in OS X Activity Monitor (green bar) - cycles/sec = iterations through the main while loop, more is better The primary area of concern here is the high percentage of time spent in the system, which appears to be driven by thread synchronization calls. As expected, for smaller work items, ExecutorService.invokeAll() will require relatively more effort to sync up the threads versus the amount of work being performed in each thread. But since ExecutorService is more generic than it would need to be for this use case (it can queue tasks for threads if there are more tasks than cores), I though maybe there would be a leaner synchronization construct. V2 - CyclicBarrier The next implementation used a CyclicBarrier to sync up the threads before receiving work and after completing it, roughly as follows: main() { // create the barrier barrier = new CyclicBarrier( 8 + 1 ); // create Runable for thread, tell it about the barrier Runnable task = new WorkerThreadRunnable( barrier ); // start the threads for( int i = 0; i < 8; i++ ) { // create one thread per core new Thread( task ).start(); } while( ... ) { // tell threads about the work ... // N threads + this will call await(), then system proceeds barrier.await(); // ... now worker threads work on the work... // wait for worker threads to finish barrier.await(); } } class WorkerThreadRunnable implements Runnable { CyclicBarrier barrier; WorkerThreadRunnable( CyclicBarrier barrier ) { this.barrier = barrier; } public void run() { while( true ) { // wait for work barrier.await(); // do the work ... // wait for everyone else to finish barrier.await(); } } } Again, this works well functionally (it does what it should), and for very large work items indeed all 8 CPUs become highly loaded, as before. However, as the work items become smaller, the load still shrinks dramatically: blocksize | system | user | cycles/sec 256k 1.9% 85% 1.30 64k 2.7% 78% 6.1 16k 5.5% 52% 25 4096 9% 29% 64 1024 11% 15% 117 256 12% 8% 169 64 12% 6.5% 285 16 12% 6% 377 For large work items, synchronization is negligible and the performance is identical to V1. But unexpectedly, the results of the (highly specialized) CyclicBarrier seem MUCH WORSE than those for the (generic) ExecutorService: throughput (cycles/sec) is only about 1/4th of V1. A preliminary conclusion would be that even though this seems to be the advertised ideal use case for CyclicBarrier, it performs much worse than the generic ExecutorService. V3 - Wait/Notify + CyclicBarrier It seemed worth a try to replace the first cyclic barrier await() with a simple wait/notify mechanism: main() { // create the barrier // create Runable for thread, tell it about the barrier // start the threads while( ... ) { // tell threads about the work // for each: workerThreadRunnable.setWorkItem( ... ); // ... now worker threads work on the work... // wait for worker threads to finish barrier.await(); } } class WorkerThreadRunnable implements Runnable { CyclicBarrier barrier; @NotNull volatile private Callable<Integer> workItem; WorkerThreadRunnable( CyclicBarrier barrier ) { this.barrier = barrier; this.workItem = NO_WORK; } final protected void setWorkItem( @NotNull final Callable<Integer> callable ) { synchronized( this ) { workItem = callable; notify(); } } public void run() { while( true ) { // wait for work while( true ) { synchronized( this ) { if( workItem != NO_WORK ) break; try { wait(); } catch( InterruptedException e ) { e.printStackTrace(); } } } // do the work ... // wait for everyone else to finish barrier.await(); } } } Again, this works well functionally (it does what it should). blocksize | system | user | cycles/sec 256k 1.9% 85% 1.30 64k 2.4% 80% 6.3 16k 4.6% 60% 30.1 4096 8.6% 41% 98.5 1024 12% 23% 202 256 14% 11.6% 299 64 14% 10.0% 518 16 14.8% 8.7% 679 The throughput for small work items is still much worse than that of the ExecutorService, but about 2x that of the CyclicBarrier. Eliminating one CyclicBarrier eliminates half of the gap. V4 - Busy wait instead of wait/notify Since this app is the primary one running on the system and the cores idle anyway if they're not busy with a work item, why not try a busy wait for work items in each thread, even if that spins the CPU needlessly. The worker thread code changes as follows: class WorkerThreadRunnable implements Runnable { // as before final protected void setWorkItem( @NotNull final Callable<Integer> callable ) { workItem = callable; } public void run() { while( true ) { // busy-wait for work while( true ) { if( workItem != NO_WORK ) break; } // do the work ... // wait for everyone else to finish barrier.await(); } } } Also works well functionally (it does what it should). blocksize | system | user | cycles/sec 256k 1.9% 85% 1.30 64k 2.2% 81% 6.3 16k 4.2% 62% 33 4096 7.5% 40% 107 1024 10.4% 23% 210 256 12.0% 12.0% 310 64 11.9% 10.2% 550 16 12.2% 8.6% 741 For small work items, this increases throughput by a further 10% over the CyclicBarrier + wait/notify variant, which is not insignificant. But it is still much lower-throughput than V1 with the ExecutorService. V5 - ? So what is the best synchronization mechanism for such a (presumably not uncommon) problem? I am weary of writing my own sync mechanism to completely replace ExecutorService (assuming that it is too generic and there has to be something that can still be taken out to make it more efficient). It is not my area of expertise and I'm concerned that I'd spend a lot of time debugging it (since I'm not even sure my wait/notify and busy wait variants are correct) for uncertain gain. Any advice would be greatly appreciated.

• NPE when drawing TabWidget in android (only on HTC Magic?)

  - by David Hedlund

  I've received report from the user of an app I've written that he gets FC whenever starting a certain activity. I have not been able to reproduce the issue on the emulator or on my HTC Hero (running 1.5), but this user running HTC Magic (with 1.6) is facing this error every time. What bothers me is that no single step in the stacktrace actually includes any code in my app (com.filmtipset) 01-07 00:10:26.773 I/ActivityManager( 141): Starting activity: Intent { cmp=com.filmtipset/.ViewMovie (has extras) } 01-07 00:10:27.023 D/AndroidRuntime( 2402): Shutting down VM 01-07 00:10:27.023 W/dalvikvm( 2402): threadid=3: thread exiting with uncaught exception (group=0x4001e170) 01-07 00:10:27.023 E/AndroidRuntime( 2402): Uncaught handler: thread main exiting due to uncaught exception 01-07 00:10:27.083 E/AndroidRuntime( 2402): java.lang.NullPointerException 01-07 00:10:27.083 E/AndroidRuntime( 2402): at android.widget.TabWidget.dispatchDraw(TabWidget.java:173) 01-07 00:10:27.083 E/AndroidRuntime( 2402): at android.view.ViewGroup.drawChild(ViewGroup.java:1529) 01-07 00:10:27.083 E/AndroidRuntime( 2402): at android.view.ViewGroup.dispatchDraw(ViewGroup.java:1258) 01-07 00:10:27.083 E/AndroidRuntime( 2402): at android.view.ViewGroup.drawChild(ViewGroup.java:1529) 01-07 00:10:27.083 E/AndroidRuntime( 2402): at android.view.ViewGroup.dispatchDraw(ViewGroup.java:1258) 01-07 00:10:27.083 E/AndroidRuntime( 2402): at android.view.ViewGroup.drawChild(ViewGroup.java:1529) 01-07 00:10:27.083 E/AndroidRuntime( 2402): at android.view.ViewGroup.dispatchDraw(ViewGroup.java:1258) 01-07 00:10:27.083 E/AndroidRuntime( 2402): at android.view.View.draw(View.java:6552) 01-07 00:10:27.083 E/AndroidRuntime( 2402): at android.widget.FrameLayout.draw(FrameLayout.java:352) 01-07 00:10:27.083 E/AndroidRuntime( 2402): at android.view.ViewGroup.drawChild(ViewGroup.java:1531) 01-07 00:10:27.083 E/AndroidRuntime( 2402): at android.view.ViewGroup.dispatchDraw(ViewGroup.java:1258) 01-07 00:10:27.083 E/AndroidRuntime( 2402): at android.view.View.draw(View.java:6552) 01-07 00:10:27.083 E/AndroidRuntime( 2402): at android.widget.FrameLayout.draw(FrameLayout.java:352) 01-07 00:10:27.083 E/AndroidRuntime( 2402): at com.android.internal.policy.impl.PhoneWindow$DecorView.draw(PhoneWindow.java:1883) 01-07 00:10:27.083 E/AndroidRuntime( 2402): at android.view.ViewRoot.draw(ViewRoot.java:1332) 01-07 00:10:27.083 E/AndroidRuntime( 2402): at android.view.ViewRoot.performTraversals(ViewRoot.java:1097) 01-07 00:10:27.083 E/AndroidRuntime( 2402): at android.view.ViewRoot.handleMessage(ViewRoot.java:1613) 01-07 00:10:27.083 E/AndroidRuntime( 2402): at android.os.Handler.dispatchMessage(Handler.java:99) 01-07 00:10:27.083 E/AndroidRuntime( 2402): at android.os.Looper.loop(Looper.java:123) 01-07 00:10:27.083 E/AndroidRuntime( 2402): at android.app.ActivityThread.main(ActivityThread.java:4320) 01-07 00:10:27.083 E/AndroidRuntime( 2402): at java.lang.reflect.Method.invokeNative(Native Method) 01-07 00:10:27.083 E/AndroidRuntime( 2402): at java.lang.reflect.Method.invoke(Method.java:521) 01-07 00:10:27.083 E/AndroidRuntime( 2402): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:791) 01-07 00:10:27.083 E/AndroidRuntime( 2402): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:549) 01-07 00:10:27.083 E/AndroidRuntime( 2402): at dalvik.system.NativeStart.main(Native Method) Full dump here if I've missed anything of interest I'm guessing, then, that there might be something wrong with my layout. It's quite verbose, so I'm posting it here, rather than pasting the whole thing on SO. There is a tabwidget, where one tab is connected to the scrollview, svFilmInfo, and one to the linear layout llComments. The tab host is populated as such: Drawable commentSelector = getResources().getDrawable(R.drawable.tabcomment); Drawable infoSelector = getResources().getDrawable(R.drawable.tabinfo); mTabHost = getTabHost(); mTabHost.getTabWidget().setBackgroundColor(Color.BLACK); mTabHost.addTab(mTabHost.newTabSpec("tabInfo").setIndicator("Filminfo", infoSelector).setContent(R.id.svFilmInfo)); mTabHost.addTab(mTabHost.newTabSpec("tabInfo").setIndicator("Kommentarer", commentSelector).setContent(R.id.llComments)); Since I cannot reproduce the error myself, and since I cannot find any mention in the stack trace of what might be causing the error, I don't quite know where to start troubleshooting this. I'd appreciate any pointers.

• After downloading an application with two Launcher components from the Marketplace, clicking "Open"

  - by user267728

• How to show an image on jasper report?

  - by spderosso

  Hi, I want to show an image on a jasper report. I have the following on the .jrxml: <image> <reportElement x="181" y="0" width="209" height="74"/> <imageExpression class="java.lang.String"><![CDATA["logo.jpg"]]></imageExpression> </image> The image logo.jpg is in the same directory as the .jrxml. By just putting that it didn't work for me. I googled a bit and found out that jasper report considers what i put on the .jrxml as a relative path to the JVM directory and that to change this I need to pass as a "REPORT_FILE_RESOLVER" parameter a FileResolver that returns the file. So, I did the following in my .java (is located in same place as the .jrxml and the image) FileResolver fileResolver = new FileResolver() { @Override public File resolveFile(String fileName) { return new File(fileName); } }; HashMap<String, Object> parameters = new HashMap<String, Object>(); parameters.put("REPORT_FILE_RESOLVER", fileResolver); ... Which should return the expected file, but I still get a net.sf.jasperreports.engine.JRException: Error loading byte data : logo.jpg at net.sf.jasperreports.engine.util.JRLoader.loadBytes(JRLoader.java:301) at net.sf.jasperreports.engine.util.JRLoader.loadBytesFromLocation(JRLoader.java:479) at net.sf.jasperreports.engine.JRImageRenderer.getInstance(JRImageRenderer.java:180) ... What am I doing wrong? Thanks!

• Facebook with RestFB

  - by Trick

  I just began to use this and I already stumbled on some from-my-side-strange errors. I am using RestFB jar. My problem is, that I can not get my session key (this is the start of everything :)). FacebookClient facebookClient = new DefaultFacebookClient(API_KEY, SECRET_KEY); try { String token = facebookClient.execute("auth.createToken", String.class, Parameter.with("null", "null")); System.out.println(token); String session = facebookClient.execute("auth.getSession", String.class, Parameter.with("auth_token", token)); System.out.println(session); } catch (FacebookException e) { e.printStackTrace(); } I get the token correctly. Parameter.with("null,"null") is there because it demands at least one, but method for creating token doesn't expect any. When trying to get the session key, I get the following error: com.restfb.FacebookResponseStatusException: Received Facebook error response (code 100): Invalid parameter at com.restfb.DefaultFacebookClient.throwFacebookResponseStatusExceptionIfNecessary(DefaultFacebookClient.java:357) at com.restfb.DefaultFacebookClient.makeRequest(DefaultFacebookClient.java:320) at com.restfb.DefaultFacebookClient.execute(DefaultFacebookClient.java:188) at com.restfb.DefaultFacebookClient.execute(DefaultFacebookClient.java:178) Documentation for getting session doesn't say any more parameters are required! Did anybody already try this JAR or do you have any other solution for Java?

• Loading JNI lib on OSX?

  - by Clinton

  Background So I am attempting to load a jnilib (specifically JOGL) into java on OSX at runtime. I have been following along the relevant stackoverflow questions: Maven and the JOGL Library Loading DLL in Java - Eclipse - JNI How to make a jar file that include all jar files The end goal for me is to package platform specific JOGL files into a jar and unzip them into a temp directory and load them at start-up. I worked my problem back to simply attempting to load JOGL using hard-coded paths: File f = new File("/var/folders/+n/+nfb8NHsHiSpEh6AHMCyvE+++TI/-Tmp-/libjogl.jnilib"); System.load(f.toString()); f = new File ("/var/folders/+n/+nfb8NHsHiSpEh6AHMCyvE+++TI/-Tmp-/libjogl_awt.jnilib"); System.load(f.toString()); I get the following exception when attempting to use the JOGL API: Exception in thread "main" java.lang.UnsatisfiedLinkError: no jogl in java.library.path But when I specify java.library.path by adding the following JVM option: -Djava.library.path="/var/folders/+n/+nfb8NHsHiSpEh6AHMCyvE+++TI/-Tmp-/" Everything works fine. Question Is it possible use System.load (or some other variant) on OSX as a replacement for -Djava.library.path that is invoked at runtime?

Are there any ways of dealing with this error without changing real field name?

• process csv in scala

  I am using scala 2.7.7, and wanted to parse CSV file and store the data in SQLite database. I ended up using OpenCSV java library to parse the CSV file, and using sqlitejdbc library. Using these java libraries makes my scala code looks almost identical to that of Java code (sans semicolon and with val/var) As I am dealing with java objects, I can't use scala list, map, etc, unless I do scala2java conversion or upgrade to scala 2.8 Is there a way I can simplify my code further using scala bits that I don't know? val filename = "file.csv"; val reader = new CSVReader(new FileReader(filename)) var aLine = new Array[String](10) var lastSymbol = "" while( (aLine = reader.readNext()) != null ) { if( aLine != null ) { val symbol = aLine(0) if( !symbol.equals(lastSymbol)) { try { val rs = stat.executeQuery("select name from sqlite_master where name='" + symbol + "';" ) if( !rs.next() ) { stat.executeUpdate("drop table if exists '" + symbol + "';") stat.executeUpdate("create table '" + symbol + "' (symbol,data,open,high,low,close,vol);") } } catch { case sqle : java.sql.SQLException => println(sqle) } lastSymbol = symbol } val prep = conn.prepareStatement("insert into '" + symbol + "' values (?,?,?,?,?,?,?);") prep.setString(1, aLine(0)) //symbol prep.setString(2, aLine(1)) //date prep.setString(3, aLine(2)) //open prep.setString(4, aLine(3)) //high prep.setString(5, aLine(4)) //low prep.setString(6, aLine(5)) //close prep.setString(7, aLine(6)) //vol prep.addBatch() prep.executeBatch() } } conn.close()

• Error in Implementing WS Security web service in WebLogic 10.3

  - by Chris

  Hi, I am trying to develop a JAX WS web service with WS-Security features in WebLogic 10.3. I have used the ant tasks WSDLC, JWSC and ClientGen to generate skeleton/stub for this web service. I have two keystores namely WSIdentity.jks and WSTrust.jks which contains the keys and certificates. One of the alias of WSIdentity.jks is "ws02p". The test client has the following code to invoke the web service: SecureSimpleService service = new SecureSimpleService(); SecureSimplePortType port = service.getSecureSimplePortType(); List credProviders = new ArrayList(); CredentialProvider cp = new ClientBSTCredentialProvider( "E:\\workspace\\SecureServiceWL103\\keystores\\WSIdentity.jks", "webservice", "ws01p","webservice"); credProviders.add(cp); string endpointURL="http://localhost:7001/SecureSimpleService/SecureSimpleService"; BindingProvider bp = (BindingProvider)port; Map requestContext = bp.getRequestContext(); requestContext.put(BindingProvider.ENDPOINT_ADDRESS_PROPERTY, endpointURL); requestContext.put(WSSecurityContext.CREDENTIAL_PROVIDER_LIST,credProviders); requestContext.put(WSSecurityContext.TRUST_MANAGER, new TrustManager() { public boolean certificateCallback(X509Certificate[] chain, int validateErr) { // Put some custom validation code in here. // Just return true for now return true; } }); SignResponse resp1 = new SignResponse(); resp1 = port.echoSignOnlyMessage("hello sign"); System.out.println("Result: " + resp1.getMessage()); When I trying to invoke this web servcie using this test client I am getting the error "Invalid signing policy" with the following stack trace: *[java] weblogic.wsee.security.wss.policy.SecurityPolicyArchitectureException: Invalid signing policy [java] at weblogic.wsee.security.wss.plan.SecurityPolicyBlueprintDesigner.verifyPolicy(SecurityPolicyBlueprintDesigner.java:786) [java] at weblogic.wsee.security.wss.plan.SecurityPolicyBlueprintDesigner.designOutboundBlueprint(SecurityPolicyBlueprintDesigner.java:136) Am I missing any configuration settings in WebLogic admin console or is it do with something else. Thanks in advance.

• Need help troubleshooting why Solr wont start (or why solr admin page wont show)

  - by Camran

  I can't get Solr working. I have Jetty, and my server OS is Ubuntu 9.10. It is a VPS server. So, when I execute the java -jar start.jar everything seems fine. I even do a netstat to check if there are any listeners on the port before the start and after the start, and it seems solr is starting. However, I cant access the admin page. I have even turned off the firewall. Here is some info about my server: I have changed DocumentRoot to var/www/SV/ I have Apache2, PHP5, MySql installed I have "disabled" iptables firewall I have removed the htaccess files (I used them to passw protect my site under develop) I have installed JRE (NOT JDK) on my server. I use the "example" which comes with Solr, so I use Jetty as container on my Server. My Server has 768MB RAM Doing a java -version command shows this: java version "1.6.0_15" Java(TM) SE Runtime Environment (build 1.6.0_15-b03) Java HotSpot(TM) Client VM (build 14.1-b02, mixed mode) And in the terminal the last lines when executing start.jar is: May 29, 2010 1:30:03 PM org.apache.solr.core.SolrCore registerSearcher INFO: [] Registered new searcher Searcher@1dc64a5 main NOTE: Also before this last line, there is a line which makes me suspicious: Started SocketConnector @ 0.0.0.0:8983 // Should this be with leading zeros? Is there any ways you know to troubleshoot this? Memory issue maybe? Thanks

• JNI loses reference to native methods

  - by lhw

  As an example for later use in Android I wrote a simple callback interface. While doing so i ran into the following error or bug or whatever. In C the two commented lines are supposed to be executed resulting in calling the C callback onChange. But instead i get an UnsatisfiedLinkError. Calling the native Method directly in Java works just fine. Calling it directly from C as presented here in the example also produces the UnsatisfiedLinkError. I'm open for any advice concerning this issue or work arounds and so on. The Java Part: import java.util.LinkedList; import java.util.Random; interface Listener { public void onChange(float f); } class Provider { LinkedList<Listener> all; public Provider() { all = new LinkedList<Listener>(); } public void registerChange(Listener lst) { all.add(lst); } public void sendMsg() { Random rnd = new Random(); for(Listener l : all) { try { l.onChange(rnd.nextFloat()); } catch(Exception e) { System.out.println(e); } } } } class Inheritance implements Listener { static public void main(String[] args) { System.load(System.getProperty("user.dir") + "/libinheritance.so"); } public native void onChange(float f); } The C Part: #include "inheritance.h" jint JNI_OnLoad(JavaVM *jvm, void *reserved) { JNIEnv *env; (*jvm)->GetEnv(jvm, (void**)&env, JNI_VERSION_1_4); inheritance = (*env)->FindClass(env, "Inheritance"); o_inheritance = (*env)->NewObject(env, inheritance, (*env)->GetMethodID(env, inheritance, "<init>", "()V")); provider = (*env)->FindClass(env, "Provider"); o_provider = (*env)->NewObject(env, provider, (*env)->GetMethodID(env, provider, "<init>", "()V")); (*env)->CallVoidMethod(env, o_inheritance, (*env)->GetMethodID(env, inheritance, "onChange", "(F)V"), 1.0); //(*env)->CallVoidMethod(env, o_provider, (*env)->GetMethodID(env, provider, "registerChange", "(LListener;)V"), o_inheritance); //(*env)->CallVoidMethod(env, o_provider, (*env)->GetMethodID(env, provider, "sendMsg", "()V")); (*env)->DeleteLocalRef(env, o_inheritance); (*env)->DeleteLocalRef(env, o_provider); return JNI_VERSION_1_4; } JNIEXPORT void JNICALL Java_Inheritance_onChange(JNIEnv *env, jobject self, jfloat f) { printf("[C] %f\n", f); } The header file: #include <jni.h> /* Header for class Inheritance */ #ifndef _Included_Inheritance #define _Included_Inheritance #ifdef __cplusplus extern "C" { #endif jclass inheritance, provider; jobject o_inheritance, o_provider; /* * Class: Inheritance * Method: onChange * Signature: (F)V */ JNIEXPORT void JNICALL Java_Inheritance_onChange(JNIEnv *, jobject, jfloat); jint JNI_OnLoad(JavaVM *, void *); #ifdef __cplusplus } #endif #endif Compilation: gcc -c -fPIC -I /usr/lib/jvm/java-6-openjdk/include -I /usr/lib/jvm/java-6-openjdk/include/linux/inheritance.c inheritance.h gcc -g -o -shared libinheritance.so -shared -Wl,-soname,libinheritance.so -lc inheritance.o

• JNI problem when calling a native library that loads another native library

  - by TheEnemyOfQuality

  I've got a bit of an odd problem. I have a project in C++ that's basically a wrapper for a third party DLL like this: MyLibrary --loads DLL_A ----loads DLL_B I load DLL_A with LoadLibrary(), wrap several of its functions and generate my own DLL. I've tested this in a C++ project and a C# project. Both do everything they're supposed to do: load DLL_A, make a couple of function calls, and indirectly load DLL_B. The problem is when I build a DLL for java and make the calls through JNI. Everything runs like it should (no java.lang.UnsatisfiedLinkError), but when it comes time for DLL_A to load DLL_B it doesn't work. From debugging, the loading of DLL_B happens on a function call in DLL_A that takes a callback. When called from Java, this function call seems to fail (the function pointer is fine and the actual call goes off without a hitch), and I get an odd pop-up window saying DLL_B failed to load, and my program is left waiting for a callback that never happens. I can explicitly load DLL_B just fine (both from Java and from C++) and I've checked every possible path, path variable, and tried placing the dlls everywhere to see if it could be looking somewhere funny. I'm pretty sure it's not a path problem. Ultimately I don't know how DLL_A is loading DLL_B and I can't figure out why everything works fine in C++ and C#, but not in Java. I'm absolutely flummoxed. It could still be something specific to my setup (although I've looked as hard as I can look), but I'm throwing this scenario out there to see if anyone has run into a similar problem. -Dave
