  • 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.

  • process csv in scala

    - by portoalet
    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()

  • 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

  • persistence.xml ignores Hibernate and chooses DataNucleus

  • How to express inter project dependencies in Eclipse PDE

    - by Roland Tepp
    I am looking for the best practice of handling inter project dependencies between mixed project types where some of the projects are eclipse plug-in/OSGI bundle projects (an RCP application) and others are just plain old java projects (web services modules). Few of the eclipse plug-ins have dependencies on Java projects. My problem is that at least as far as I've looked, there is no way of cleanly expressing such a dependency in Eclipse PDE environment. I can have plug-in projects depend on other plug-in projects (via Import-Package or Require-Bundle manifest headers), but not of the plain java projects. I seem to be able to have project declare a dependency on a jar from another project in a workspace, but these jar files do not get picked up by neither export nor launch configuration (although, java code editing sees the libraries just fine). The "Java projects" are used for building services to be deployed on an J2EE container (JBoss 4.2.2 for the moment) and produce in some cases multiple jar's - one for deploying to the JBoss ear and another for use by client code (an RCP application). The way we've "solved" this problem for now is that we have 2 more external tools launcher configurations - one for building all the jar's and another for copying these jar's to the plug-in projects. This works (sort of), but the "whole build" and "copy jars" targets incur quite a large build step, bypassing the whole eclipse incremental build feature and by copying the jars instead of just referencing the projects I am decoupling the dependency information and requesting quite a massive workspace refresh that eats up the development time like it was candy. What I would like to have is a much more "natural" workspace setup that would manage dependencies between projects and request incremental rebuilds only as they are needed, be able to use client code from service libraries in an RCP application plug-ins and be able to launch the RCP application with all the necessary classes where they are needed. So can I have my cake and eat it too ;) NOTE To be clear, this is not so much about dependency management and module management at the moment as it is about Eclipse PDE configuration. I am well aware of products like [Maven], [Ivy] and [Buckminster] and they solve a quite different problem (once I've solved the workspace configuration issue, these products can actually come in handy for materializing the workspace and building the product)

  • Static Data Structures on Embedded Devices (Android in particular)

    - by Mark
    I've started working on some Android applications and have a question regarding how people normally deal with situations where you have a static data set and have an application where that data is needed in memory as one of the standard java collections or as an array. In my current specific issue i have a spreadsheet with some pre-calculated data. It consists of ~100 rows and 3 columns. 1 Column is a string, 1 column is a float, 1 column is an integer. I need access to this data as an array in java. It seems like i could: 1) Encode in XML - This would be cpu intensive to decode in my experience. 2) build into SQLite database - seems like a lot of overhead for static access to data i only need array style access to in ram. 3) Build into binary blob and read in. (never done this in java, i miss void *) 4) Build a python script to take the CSV version of my data and spit out a java function that adds the values to my desired structure with hard coded values. 5) Store a string array via androids resource mechanism and compute the other 2 columns on application load. In my case the computation would require a lot of calls to Math.log, Math.pow and Math.floor which i'd rather not have to do for load time and battery usage reasons. I mostly work in low power embedded applications in C and as such #4 is what i'm used to doing in these situations. It just seems like it should be far easier to gain access to static data structures in java/android. Perhaps I'm just being too battery usage conscious and in my single case i imagine the answer is that it doesn't matter much, but if every application took that stance it could begin to matter. What approaches do people usually take in this situation? Anything I missed?

  • Why won't the VisualVM Profiler profile my application?

    - by Luke
    I've created a simple 1 file java application that iterates through a loop, calls some functions, allocates some memory, adds some numbers, etc. I run that application via eclipse's Run As->Java Application. The running application shows up in Java VisualVM under Local. I double click on that application and go to the Profiler tab. The default settings are: Start profiling from classes: my.main.package.** Do not profile classes: java.*, javax.*, sun.*, sunw.*, com.sun.* I click on CPU. The CPU and Memory buttons gray out. Nothing happens. The Status says profiling inactive. When my application terminates the Status says application terminated. What am I doing wrong here? Are there some settings I need to tweak? Do I need to set a VM flag when I launch my application?

  • Container Options in AWS Elastic Beanstalk

    - by Sangram Anand
    We have deployed a java webapplication in Elastic Beanstalk with the minimum instance count 1 and max instance count 2 for Autoscaling. The custom AMI we are using is c1.medium with Sun JDK 6. The environment status changed to yellow and then red. After checking into the log file from the snapshot logs we found a exception - Caused by: java.lang.OutOfMemoryError: Java heap space. Assuming this could be one of the possible reason for the Environment failure. The settings that we have configured in the Environment Container option are Initial JVM Heap Size (MB) - 256M Maximum JVM Heap Size (MB) - 512m The maximum heap size the java virtual machine will ever consume, specified on the JVM launch command line using -Xmx. Maximum JVM Permanent Generation Size (MB) - 512m Should i increase the Heap size from 512m to more or is it fine.

  • Illegal start of expression?

    - by Fraser
    I'm trying to build a simple Android app that increments a number displayed every time a button is pressed, but I can't work out how to fix the "illegal start of expression" error I keep getting. My code: package com.clicker; import android.app.Activity; import android.os.Bundle; import android.view.View; import android.widget.Button; import android.widget.TextView; public class Clicker extends Activity { private int clickerNumber = 0; private TextView clickerText; private Button clickerButton; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); clickerText = (TextView)findViewById(R.id.clickerText); final Button clickerButton = (Button)findViewById(R.id.clickerButton); clickerButton.setOnClickListener(new View.OnClickListener()); { public void onClick(); { clickerNumber = clickerNumber++; clickerText.setText(Integer.toString(clickerNumber)); } } } } And compiler output: compile: [javac] Compiling 2 source files to /home/fraser/Applications/Android/Code/Clicker/bin/classes [javac] /home/fraser/Applications/Android/Code/Clicker/src/com/clicker/Clicker.java:24: ')' expected [javac] clickerButton.setOnClickListener(new View.OnClickListener(); [javac] ^ [javac] /home/fraser/Applications/Android/Code/Clicker/src/com/clicker/Clicker.java:26: illegal start of expression [javac] public void onClick(); [javac] ^ [javac] /home/fraser/Applications/Android/Code/Clicker/src/com/clicker/Clicker.java:26: illegal start of expression [javac] public void onClick(); [javac] ^ [javac] /home/fraser/Applications/Android/Code/Clicker/src/com/clicker/Clicker.java:26: ';' expected [javac] public void onClick(); [javac] ^ [javac] /home/fraser/Applications/Android/Code/Clicker/src/com/clicker/Clicker.java:29: ';' expected [javac] clickerText.setText(Integer.toString(clickerNumber))); [javac] ^ [javac] 5 errors

  • Write a MAT file without using matlab headers and libraries.

    - by YuppieNetworking
    Hello all, I have some data that I would like to save to a MAT file (version 4 or 5, or any version, for that matter). The catch: I wanted to do this without using matlab libraries, since this code will not necessary run in a machine with matlab. My program uses Java and C++, so any existing library in those languages that achieves this could help me out... I did some research but did not find anything in Java/C++. However, I found that scipy on python achieves this with mio4.py or mio5.py. I thought about implementing this on java or C++, but it seems a bit out of my time schedule. So the question is: is there any libraries in Java or C/C++ that permits saving MAT files without using Matlab libraries? Thanks a lot

  • Using reflection to change static final File.separatorChar for unit testing?

    - by Stefan Kendall
    Specifically, I'm trying to create a unit test for a method which requires uses File.separatorChar to build paths on windows and unix. The code must run on both platforms, and yet I get errors with JUnit when I attempt to change this static final field. Anyone have any idea what's going on? Field field = java.io.File.class.getDeclaredField( "separatorChar" ); field.setAccessible(true); field.setChar(java.io.File.class,'/'); When I do this, I get IllegalAccessException: Can not set static final char field java.io.File.separatorChar to java.lang.Character Thoughts?

  • weird swing heavyweight object lightweight objects problem

    - by Yoav Schwartz
    Hello, We have a problem in our swing based application since we've upgraded our java version from 6u5 to 6u18 (The application runs over WinXP). Our application contains a Canvas object which resides in a JFrame. The application draws things on the canvas. Every time we drag a lightweight swing object (popup or another frame) over the canvas, it has a refresh problem. It blinks - becomes black. The problem only resolves after we move the swing component away from the canvas and click on it again. We think this problem is related to the fact the the canvas is a heavyweight object. And we know there were changes done in the new versions of java on the mixing of heavyweight and lightweight objects issue. Some more details: 1) Our problem reproduces in java 6u14 and 6u16. 2) Everything works fine in java 6u5. Another strange thing: We have 2 types of stations running our application. The first type has a ATI FireGL7100 PCI-E graphics card. The second type has a Matrox G450 PCI graphic card. The problem does not reproduce on the Matrox based station in any java version. One more thing: http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6829858 - looks similar to our problem. Is our problem familiar? Do you have any suggestions (workarounds, ideas how the difference in graphics cards is connected to this problem) Hope I was clear enough, Yoav

  • Serverside image processing

    - by spol
    I am designing a web application that does server side image processing in real time. Processing tasks include applying different effects like grayscale, blur, oil paint, pencil sketch etc on images in various formats. I want to build it using java/servlets which I am already familiar with. I found 3 options, 1) Use pure java imaging libraries like java.awt or http://www.jhlabs.com/ip/index.html 2) Use command line tools like Gimp/ImageMagick 3) Use c,c++ image libraries that have java bindings. I don't know which of the above options is good keeping the performance in mind. It looks like option 2) and 3) are good performance wise, but I want to be sure before I rule out 1). I have also heard gimp cannot be run using command line unless gtk or xwindows is already installed on the server. Will there be any such problems with 2) or 3) while running them server side? Also please suggest any good image processing libraries for this purpose.

    When using ANT to build my Java application I keep getting this error. I have tried multiple times to use SQLJDBC.JAR and SQLJDBC4.JAR but continually receive this error message. I am completely stumpped why this error is received even after upgrading to sqljdbc4.jar. [javadoc] java.lang.UnsupportedOperationException: Java Runtime Environment (JRE) version 1.6 is not supported by this driver. Use the sqljdbc4.jar class library, which provides support for JDBC 4.0.
