  • wsimport generate a client with cookies

    - by dierre
    I'm generating a client for a SOAP 1.2 service using wsimport from the jaxws-maven-plugin in maven with the following execution: <groupId>org.jvnet.jax-ws-commons</groupId> <artifactId>jaxws-maven-plugin</artifactId> <version>2.2</version> <executions> <execution> <goals> <goal>wsimport</goal> </goals> <configuration> <sourceDestDir>${project.basedir}/src/main/java</sourceDestDir> <wsdlUrls> <wsdlUrl>${webservice.url}</wsdlUrl> </wsdlUrls> <extension>true</extension> </configuration> </execution> The first time the client call the proxy, the load balancer generate a cookie and sends it back. The client should send it back so the load balancer knows where (which server) is dedicated to a specific client (the idea is that the first time the client get a server and the cookie identifies the server, then the load balancer sends the client to the same server for every call) Now, is there a way to tell to the plugin to enable automatically the cookie handling?

  • How does an open source project get funded?

    - by squillman
    Other than large entities sponsoring a project, such as the Apache foundation, what are other ways that full-time open source developers (specifically those on products offered free of charge) receive funding for their projects? Obviously there will be donations that will trickle in but from what other channels do developers receive more steady income?

  • log4j performance

    - by Bob
    Hi, I'm developing a web app, and I'd like to log some information to help me improve and observe the app. (I'm using Tomcat6) First I thought I would use StringBuilders, append the logs to them and a task would persist them into the database like every 2 minutes. Because I was worried about the out-of-the-box logging system's performance. Then I made some test. Especially with log4j. Here is my code: Main.java public static void main(String[] args) { Thread[] threads = new Thread[LoggerThread.threadsNumber]; for(int i = 0; i < LoggerThread.threadsNumber; ++i){ threads[i] = new Thread(new LoggerThread("name - " + i)); } LoggerThread.startTimestamp = System.currentTimeMillis(); for(int i = 0; i < LoggerThread.threadsNumber; ++i){ threads[i].start(); } LoggerThread.java public class LoggerThread implements Runnable{ public static int threadsNumber = 10; public static long startTimestamp; private static int counter = 0; private String name; public LoggerThread(String name) { this.name = name; } private Logger log = Logger.getLogger(this.getClass()); @Override public void run() { for(int i=0; i<10000; ++i){ log.info(name + ": " + i); if(i == 9999){ int c = increaseCounter(); if(c == threadsNumber){ System.out.println("Elapsed time: " + (System.currentTimeMillis() - startTimestamp)); } } } } private synchronized int increaseCounter(){ return ++counter; } } } log4j.properties log4j.logger.main.LoggerThread=debug, f log4j.appender.f=org.apache.log4j.RollingFileAppender log4j.appender.f.layout=org.apache.log4j.PatternLayout log4j.appender.f.layout.ConversionPattern=%d{ABSOLUTE} %5p %c{1}:%L - %m%n log4j.appender.f.File=c:/logs/logging.log log4j.appender.f.MaxFileSize=15000KB log4j.appender.f.MaxBackupIndex=50 I think this is a very common configuration for log4j. First I used log4j 1.2.14 then I realized there was a newer version, so I switched to 1.2.16 Here are the figures (all in millisec) LoggerThread.threadsNumber = 10 1.2.14: 4235, 4267, 4328, 4282 1.2.16: 2780, 2781, 2797, 2781 LoggerThread.threadsNumber = 100 1.2.14: 41312, 41014, 42251 1.2.16: 25606, 25729, 25922 I think this is very fast. Don't forget that: in every cycle the run method not just log into the file, it has to concatenate strings (name + ": " + i), and check an if test (i == 9999). When threadsNumber is 10, there are 100.000 loggings and if tests and concatenations. When it is 100, there are 1.000.000 loggings and if tests and concatenations. (I've read somewhere JVM uses StringBuilder's append for concatenation, not simple concatenation). Did I missed something? Am I doing something wrong? Did I forget any factor that could decrease the performance? If these figures are correct I think, I don't have to worry about log4j's performance even if I heavily log, do I?

  • How to use Struts 2 with JFreeChart?

    - by Pere
    Firstly, I went here ( http://code.google.com/p/struts2-examples/downloads/list and I downloaded Hello_World_Struts2_Mvn.zip) and I run that example.

  • #1130 - Host ‘localhost’ is not allowed to connect to this MySQL server

    - by Raph
    I accidently changed the "host" value for the root user inside of the user table for mysql. I need to change it back to localhost because I changed it to arancillary2125 (my other machines DNS name) but I cannot access mysql (from PHPMYADMIN or command prompt) due to "localhost" not having permissions anymore. I am running windows XP // apache // I have tried the following solutions but they didn't work: http://serverfault.com/questions/92870/1130-host-localhost-is-not-allowed-to-connect-to-this-mysql-server

To be specified. $a="/home/apache/a/a.php"; $b="/home/root/b/b.php"; $relpath = getRelativePath($a,$b);//needed function,should return '../../root/b/b.php' Any good ideas?Thanks.

  • (resolved) empty response body in ajax (or 206 Partial Content)

    - by Nikita Rybak
    Hi guys, I'm feeling completely stupid because I've spent two hours solving task which should be very simple and which I solved many times before. But now I'm not even sure in which direction to dig. I fail to fetch static content using ajax from local servers (Apache and Mongrel). I get responses 200 and 206 (depending on the server), empty response text (although Content-Length header is always correct), firebug shows request in red. Javascript is very generic, I'm getting same results even here: http://www.w3schools.com/ajax/tryit.asp?filename=tryajax_first (just change document location to 'http://localhost:3000/whatever') So, it's probably not the cause. Well, now I'm out of ideas. I can also post http headers, if it'll help. Thanks!

  • oracle hibernate + maven dependenciesm dbcp.basicdatasource exception

    - by Joe
    I'm trying to create a web application using maven, tomcat and hibernate. Now I'm getting a cannot find class for org.appache.commons.dbcp.basicdatasource for bean with name datasource... exception. Without the hibernate aspects it works fine, but if I add <bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean"> <property name="dataSource" ref="dataSource"/> <property name="hibernateProperties"> <props> <prop key="hibernate.dialect">org.hibernate.dialect.Oracle10gDialect</prop> <prop key="hibernate.hbm2ddl.auto">create</prop> <prop key="hibernate.show_sql">true</prop> </props> </property> <property name="mappingResources"> <list> </list> </property> </bean> to my applicationContext then I get the error. What I did was: -add org.hibernate to my pom -put ojdbc16.jar in my tomcat bin folder -add the above snippet to my applicationContext.xml I use a bat file to compile my project (using maven), copy it to my tomcat webapp folder and to start the server. Any input on what I'm doing wrong is welcome.

  • php POST and non-english language passes empty

    - by haim evgi
    I'm trying to program a Hebrew site with a search option. I am using php 5 with Apache 2.2, on a Debian 5 (Lenny) with appropriate code pages enabled. I am using _POST to pass arguments to a script. If I pass English word to the script everything works, but when I use Hebrew nothing is passed through the POST function. When I use ECHO to show _POST, the variable is empty. What might be the problem?

  • ant ftp task "Could not date test remote file"

    - by avok00
    Hi guys! I am using Ant ftp task to deploy my project files to a remote app server. Ant is not able to detect the date of the remote file and it re-uploads all files every time. When I start Ant in debug mode it says: [ftp] checking date for mailer.war [ftp] Could not date test remote file: mailer.war assuming out of date. The remote server is MS FTP (Windows Vista version) Ant version is 1.8.2; I use commons-net-2.2 and jakarta-oro-2.0.8 (could not find newer version) My ant task looks like this <!-- Deploy new and changed files --> <target name="deploy" depends="package" description="Deploy new and changed files"> <ftp server="localhost" userid="" password="" action="send" depends="yes" passive="true" systemTypeKey="WINDOWS" serverTimeZoneConfig="Europe/Sofia" defaultDateFormatConfig="MMM dd yyyy" recentDateFormatConfig="MMM dd HH:mm" binary="true" retriesAllowed="3" verbose="true"> <fileset dir="${webapp.artefacts.path}"/> </ftp> </target> I read an article here: Ant:The definitive guide that says I need a version of jakarta oro AFTER 2.0.8 to talk to MS FTP servers, but I was not able to find such version. Jakarta oro site - http://jakarta.apache.org/oro/ says the oro project is retired as of 2010, but their latest distribution is from 2003! Please, can anyone help me with this? Any solution or any alternatives to the Ant ftp task? Thanks!

  • Heroku powered private restricted beta

    - by Ben Sand
    I'd like to run an app in a restricted private beta on heroku. We're changing the app regularly and haven't done a security audit. To stop anyone exploiting stuff, we'd like to lock down the whole site, so you need a password to access anything. Ideally similar to using .htaccess and .htpasswd files to lock an entire site on an Apache server. Is there a simple one shot way to do this for a heroku hosted app?

  • Failed to obtain JDBC Driver for MySQL under Tomcat environment

    - by Michael Mao
    Hi all: I've been trying to obtain the Driver class for JDBC connection to MySQL. The workstation is running on Linux, Fedora 10. I have manually set up the classpath variable for Java by CLI like this: bash-3.2$ echo $CLASSPATH /home/cmao/public_html/jsp/mysql-connector-java-5.1.12-bin.jar This shows that I've added the lastest mysql connection jar archive to my CLASSPATH variable. I've created a test JSP page which can be found here And source code for this page is: <%@page language="java"%> <%@page import="java.sql.*"%> <%@page import="java.util.*"%> <html> <head> <title>UTS JDBC MySQL connection test page</title> </head> <body> <% Connection con = null; out.print("Java version is : " + System.getProperty("java.version") + "<br />"); out.print("Tomcat version is : " + application.getServerInfo() + "<br />"); out.print("Servlet version is: " + application.getMajorVersion() + "<br />"); out.print("JSP version is : " + JspFactory.getDefaultFactory().getEngineInfo().getSpecificationVersion() +"<br />"); //out.print("Java classpath is : " + System.getProperty("java.class.path")+ "<br />"); //out.print("JSP classpath is : " + appliaction.getAttribute("org.apache.catalina.jsp_classpath") + "<br />"); //out.print("Tomcat classpath is : " + System.getProperty("org.apache.tomcat.common.classpath") + "<br />"); try { Class c = Class.forName("com.mysql.jdbc.Driver"); } catch(Exception e) { out.println("Error! Failed to obtain JDBC driver for MySQL... Missing class \"com.mysql.jdbc.Driver\"<br />"); } %> </body> </html> None of those commented out line would work, various Jsper Expetions would be thrown. You can check those Error pages from the following links: classpath Error page catalina Error page tomcat Error page It seems, from my limited knowledge of JSP and Servlet, the Tomcat environment "ignores" my Java CLASSPATH? In which case I cannot configure the MySQL JDBC package to let my Servlets(a JSP is but a Servlet anyway) work. I am not sure how to fix this issue. would it be better if I use an IDE like Eclipse or NetBeans and create a real Java "web app" so that everything can be "self-configured" by the usage of a web.config XML configuration file? So that I can certainly bypass this Tomcat environment restriction? Many thanks for the suggestions in advance.
