  • How to allow anonymous login in org.apache.ftpserver?

    - by ablmf
    I wrote a little code like this to start an ftp server embedded in my application. It's based on apache ftpserver I found that anonymous user could not login. Client keeps get 530. Do I have add a configure file for ftp? I can not find any API to create a User to add to UserManger. private void start_ftp() throws FtpException { FtpServerFactory serverFactory = new FtpServerFactory(); ListenerFactory factory = new ListenerFactory(); // set the port of the listener factory.setPort(DEF_FTP_PORT); // replace the default listener serverFactory.addListener("default", factory.createListener()); Ftplet fl = new MyFtplet(); Map<String, Ftplet> map_ftplest = new LinkedHashMap<String, Ftplet>(); map_ftplest.put("default", fl); serverFactory.setFtplets(map_ftplest); UserManagerFactory u_factory = new PropertiesUserManagerFactory(); UserManager u_manager = u_factory.createUserManager(); //u_manager. Boolean b = u_manager.doesExist("anonymous"); serverFactory.setUserManager(u_manager); // start the server server = serverFactory.createServer(); server.start(); }

  • Testing JavaMail Related Modules

    - by Hamza Yerlikaya
    Part of my application depends on JavaMail, moving arranging messages etc. Is it possible to test this module without firing a IMAP server to run the tests on? I am always stuck when it comes to testing stuff that depends on external servers or modules.

  • EJB 3 Session Bean Design for Simple CRUD

    - by sdoca
    I am writing an application that's sole purpose in life is to do CRUD operations for maintaining records in database. There are relationships between some of the tables/entities. Most examples I've seen for creating session beans deals with complex business logic/operations that interact with many entities which I don't have. Since my application is so very basic, what would be the best design for the session bean(s)? I was thinking of having one session bean per entity which had CRUD the methods defined. Then I thought of combining all of those session beans into a single session bean. And then I found this blog entry which is intriguing, but I must admit I don't understand all of it (what is a ServiceFacade?). I'm leaning towards session bean/entity class, but would like to hear more experienced opinions. Thanks.

  • Spring @Autowired and WebApplicationContext in Tomcat

    - by EugeneP
    @Autowired works only once. What to do to make it wire the bean every time the Servlet is recreated? My web-app (Tomcat6 container) consists of 2 Servlets. Every servlet has private fields. Their setters are marked with @Autowired In the init method I use WebApplicationContextUtils ... autowireBean(this); It autowires the properties marked with @Autowired once - during the initialization of the Servlet. Any other session will see these fields values, they will not be rewired after the previous session is destroyed. What to do to make them rewire them each time a Servlet constructor is called? a) Put the autowiring into the constructor? Or better 2) get a web app context and extract a bean from there?

  • call lynx from jsp script

    - by Piero
    Hi, I have an execute(String cmd) in a jsp script that calls the exec method from the Runtime class. It works when I call a local command, like a php script stored on the server. for example: /usr/bin/php /path/to/php/script arg1 arg2 So I guess my execute command is ok, since it is working with that. Now when I try to call lynx, the text-based web browser, it does not work. If I call it in a terminal, it works fine: /usr/bin/lynx -dump -accept_all_cookies 'http://www.someurl.net/?arg1=1&arg2=2' But when I call this from my execute command, nothing happens... Any idea why? This is my execute method: public String execute(String cmd){ Runtime r = Runtime.getRuntime(); Process p = null; String res = ""; try { p = r.exec(cmd); InputStreamReader isr = new InputStreamReader(p.getInputStream()); BufferedReader br = new BufferedReader(isr); String line = null; //out.println(res); while ((line = br.readLine()) != null) { res += line; } p.waitFor(); } catch (Exception e) { res += e; } System.out.println(p.exitValue()); return res; }

  • Algorithm to aggregate values from child tree nodes

    - by user222164
    I have objects in a tree structure, I would like to aggregate status information from children nodes and update parent node with aggregated status. Lets say node A has children B1, B2, and B1 has C1, C2, C3 as children. Each of the nodes have a status attribute. Now if C1, C2, C3 are all complete then I would like to mark B1 as completed. And if C4, C5,C6,C7 are complete make B2 as complete. When B1 and B2 are both complete mark A as complete. I can go through these nodes in brute force method and make updates, could someone suggest an efficient algorithm to do it. A { B1 { C1, C2, C3}, B2 { C4, C5, C6, C7} }

  • Progress Dialog in Android doesn't Show?

    - by Tyler
    Okay.. I am doing something similar to the below: private void onCreate() { final ProgressDialog dialog = ProgressDialog.show(this, "Please wait..", "Doing stuff..", true); Thread t = new Thread() { public void run() { //do some serious stuff... dialog.dismiss(); } }; t.start(); t.join(); stepTwo(); } However, what I am finding is that my progress dialog never even shows up. My App stalls for a moment so I know it is chugging along inside of thread t, but why doesnt my dialog appear? IF I remove the line: t.join(); Then what I find happens is that the progress dialog does show up, but my app starts stepTwo(); before what happens in the thread is complete.. Any ideas?

  • Why does ActiveMQ hold messages that should be deleted from Topic?

    - by rauch
    I use ActiveMQ as Notification System(Pub/Sub model). On server: if any changes of data occur, Server send this updated data (File) to Topic using BlobMessages. There are few Clients, that subscribe on this Topic and get updated File if it exsist in Topic. The problem is that all of BlobMessages, that were sent to Topic, are hold by ActiveMQ all time. this.producer = new ProducerTool.Builder("tcp://localhost:61616?jms.blobTransferPolicy.uploadUrl=http://localhost:8161/fileserver/", "ServerProdTopic").topic(true) .transacted(false).durable(false).timeToLive(10000L).build(); this.consumer = new ConsumerTool.Builder("tcp://localhost:61616", "ServerConsTopic").topic(true) .transacted(false).durable(false).build(); consumer.setMessageListener(this); The File is sent: connection = createConnection(); session = createSession(connection); producer = createProducer(session); BlobMessage blobMsg = ((ActiveMQSession) session).createBlobMessage(resource); blobMsg.setStringProperty("sourceName", resource.getName()); producer.send(blobMsg); if (transacted) { System.out.println("Producer Committing..."); session.commit(); } Where createProducer is: protected Connection createConnection() throws JMSException, Exception { ActiveMQConnectionFactory connectionFactory = new ActiveMQConnectionFactory(url); //connectionFactory.getBlobTransferPolicy().setUploadUrl("http://localhost:8161/fileserver/"); Connection connection = connectionFactory.createConnection(); connection.start(); ((ActiveMQConnection) connection).setCopyMessageOnSend(false); return connection; } All, that could be useful I set as need: Session.AUTO_ACKNOWLEDGE; Non-Durable Subscription; TimeToLive = 9000; JMSDeliveryMode = Non-Persistent; What I have at runtime: in ActiveMQ directory: ~/apache-activemq-5.3.0/webapps/fileserver/ tere are all File, that where delivered and not delivered to Subscribers. Why? Sometimes Server send Big Files about 1 GB....And even this Files are hold at that directory, Even after stopping Subscribers(Clients), Publisher(Server) and ActiveMQ Broker.

  • Apache with JBOSS using AJP (mod_jk) giving spikes in thread count.

    - by Beginner
    We used Apache with JBOSS for hosting our Application, but we found some issues related to thread handling of mod_jk. Our website comes under low traffic websites and has maximum 200-300 concurrent users during our website's peak activity time. As the traffic grows (not in terms of concurrent users, but in terms of cumulative requests which came to our server), the server stopped serving requests for long, although it didn't crash but could not serve the request till 20 mins. The JBOSS server console showed that 350 thread were busy on both servers although there was enough free memory say, more than 1-1.5 GB (2 servers for JBOSS were used which were 64 bits, 4 GB RAM allocated for JBOSS) In order to check the problem we were using JBOSS and Apache Web Consoles, and we were seeing that the thread were showing in S state for as long as minutes although our pages take around 4-5 seconds to be served. We took the thread dump and found that the threads were mostly in WAITING state which means that they were waiting indefinitely. These threads were not of our Application Classes but of AJP 8009 port. Could somebody help me in this, as somebody else might also got this issue and solved it somehow. In case any more information is required then let me know. Also is mod_proxy better than using mod_jk, or there are some other problems with mod_proxy which can be fatal for me if I switch to mod__proxy? The versions I used are as follows: Apache 2.0.52 JBOSS: 4.2.2 MOD_JK: 1.2.20 JDK: 1.6 Operating System: RHEL 4 Thanks for the help.

  • Factory Method Implementation

    - by cedar715
    I was going through the 'Factory method' pages in SO and had come across this link. And this comment. The example looked as a variant and thought to implement in its original way: to defer instantiation to subclasses... Here is my attempt. Does the following code implements the Factory pattern of the example specified in the link? Please validate and suggest if this has to undergo any re-factoring. public class ScheduleTypeFactoryImpl implements ScheduleTypeFactory { @Override public IScheduleItem createLinearScheduleItem() { return new LinearScheduleItem(); } @Override public IScheduleItem createVODScheduleItem() { return new VODScheduleItem(); } } public class UseScheduleTypeFactory { public enum ScheduleTypeEnum { CableOnDemandScheduleTypeID, BroadbandScheduleTypeID, LinearCableScheduleTypeID, MobileLinearScheduleTypeID } public static IScheduleItem getScheduleItem(ScheduleTypeEnum scheduleType) { IScheduleItem scheduleItem = null; ScheduleTypeFactory scheduleTypeFactory = new ScheduleTypeFactoryImpl(); switch (scheduleType) { case CableOnDemandScheduleTypeID: scheduleItem = scheduleTypeFactory.createVODScheduleItem(); break; case BroadbandScheduleTypeID: scheduleItem = scheduleTypeFactory.createVODScheduleItem(); break; case LinearCableScheduleTypeID: scheduleItem = scheduleTypeFactory.createLinearScheduleItem(); break; case MobileLinearScheduleTypeID: scheduleItem = scheduleTypeFactory.createLinearScheduleItem(); break; default: break; } return scheduleItem; } }

  • Advantages/disadvantages of Glassfish v3 Prelude vs Springsource dm server for Web applications?

    - by cletus
    Both of these appservers are at least in part OSGI based. One (Glassfish) is obviously J2EE while the other isn't. Now I'm at the stage of choosing a platform for a new project and the natural choice is Glassfish v3 Prelude. This does raise the issue of perhaps we should be using S2AP instead. The question then is this: does the springsource dm server offer any compelling reason to use it over Glassfish? And vice versa.

  • t:commandSortHeader not being styled

  • Why a "private static" is not seen in a method?

    - by Roman
    I have a class with the following declaration of the fields: public class Game { private static String outputFileName; .... } I set the value of the outputFileName in the main method of the class. I also have a write method in the class which use the outputFileName. I always call write after main sets value for outputFileName. But write still does not see the value of the outputFileName. It say that it's equal to null. Could anybody, pleas, tell me what I am doing wrong? ADDED As it is requested I post more code: In the main: String outputFileName = userName + "_" + year + "_" + month + "_" + day + "_" + hour + "_" + minute + "_" + second + "_" + millis + ".txt"; f=new File(outputFileName); if(!f.exists()){ try { f.createNewFile(); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } } System.out.println("IN THE MAIN!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!"); System.out.println("------>" + outputFileName + "<------"); This line outputs me the name of the file. Than in the write I have: public static void write(String output) { // Open a file for appending. System.out.println("==========>" + outputFileName + "<============"); ...... } And it outputs null.

  • Interface Design Problem: Storing Result of Transactions

    - by jboyd
    Requirements: multiple sources of input (social media content) into a system multiple destinations of output (social media api's) sources and destinations WILL be added some pseudo: IContentProvider contentProvider = context.getBean("contentProvider"); List<Content> toPost = contentProvider.getContent(); for (Content c : toPost) { SocialMediaPresence smPresence = socialMediaService.getSMPresenceBySomeId(c.getDestId()); smPresence.hasTwitter(); smPresence.hasFacebook(); //just to show what this is smPresence.postContent(c); //post content could fail for some SM platforms, but shoulnd't be lost forever } So now I run out of steam, I need to know what content has been successfully posted, and if it hasn't gone too all platforms, or if another platform were added in the future that content needs to go out for it as well (therefore my content provider will need to not only know if content has gone out, but for what platforms). I'm not looking for code, although sample/pseudo is fine... I'm looking for an approach to this problem that I can implement

  • Hibernate Validator - Using properties in the constraints xml

    - by Avi Y
    Hi, I have just started using hibernate validator. I am creating the constraints in an XML file(not annotations). The only problem I am having is that I would like to use properties inside the constraints. For example: <bean class="MyBean" > <constraint annotation="javax.validation.constraints.Min"> <element name="value">{myProperty}</element> </constraint> </bean> and I would like to define these properties in a separate file. Do you think that's possible? Any help would be appreciated.

  • Creating keystore for jarsigner programmatically

    - by skayred
    I'm trying to generate keystore with certificate to use it with JarSigner. Here is my code: System.out.println("Keystore generation..."); Security.addProvider(new BouncyCastleProvider()); String domainName = "example.org"; KeyPairGenerator keyGen = KeyPairGenerator.getInstance("RSA"); SecureRandom random = SecureRandom.getInstance("SHA1PRNG", "SUN"); keyGen.initialize(1024, random); KeyPair pair = keyGen.generateKeyPair(); X509V3CertificateGenerator v3CertGen = new X509V3CertificateGenerator(); int serial = new SecureRandom().nextInt(); v3CertGen.setSerialNumber(BigInteger.valueOf(serial < 0 ? -1 * serial : serial)); v3CertGen.setIssuerDN(new X509Principal("CN=" + domainName + ", OU=None, O=None L=None, C=None")); v3CertGen.setNotBefore(new Date(System.currentTimeMillis() - 1000L * 60 * 60 * 24 * 30)); v3CertGen.setNotAfter(new Date(System.currentTimeMillis() + (1000L * 60 * 60 * 24 * 365*10))); v3CertGen.setSubjectDN(new X509Principal("CN=" + domainName + ", OU=None, O=None L=None, C=None")); v3CertGen.setPublicKey(pair.getPublic()); v3CertGen.setSignatureAlgorithm("MD5WithRSAEncryption"); X509Certificate PKCertificate = v3CertGen.generateX509Certificate(pair.getPrivate()); FileOutputStream fos = new FileOutputStream("/Users/dmitrysavchenko/testCert.cert"); fos.write(PKCertificate.getEncoded()); fos.close(); KeyStore ks = KeyStore.getInstance(KeyStore.getDefaultType()); char[] password = "123".toCharArray(); ks.load(null, password); ks.setCertificateEntry("hive", PKCertificate); fos = new FileOutputStream("/Users/dmitrysavchenko/hive-keystore.pkcs12"); ks.store(fos, password); fos.close(); It works, but when I'm trying to sign my JAR with this keystore, I get the following error: jarsigner: Certificate chain not found for: hive. hive must reference a valid KeyStore key entry containing a private key and corresponding public key certificate chain. I've discovered that there must be a private key, but I don't know how to add it to certificate. Can you help me?
