• jcaptcha integration with struts

  - by xain

  Hi, I'm trying to interate a struts 1.3.8 app with jcaptcha-1.0; I added the jcaptcha jar to the app lib and added <%@ taglib uri="jcaptcha" prefix="jcaptcha"%> to my form The app couldn't find the file, so I added the following to the web.xml file <taglib-uri>jcaptcha</taglib-uri> <taglib-location>/WEB-INF/lib/jcaptcha-1.0-all.jar</taglib-location> </taglib> And now I get the null pointer exception: org.apache.jasper.JasperException: Unable to read TLD "META-INF/taglib.tld" from JAR file Any clues ? Thanks

• GoogleAppEngine : JAR for enhancer not found, yet ASM is on the classpath

  - by James.Elsey

  When deploying my application to GoogleAppEngine I'm getting the following message after the upload Exception in thread "Thread-0" You have selected to use ClassEnhancer "ASM" yet the JAR for that enhancer does not seem to be in the CLASSPATH! org.datanucleus.enhancer.NucleusEnhanceException: You have selected to use ClassEnhancer "ASM" yet the JAR for that enhancer does not seem to be in the CLASSPATH! at org.datanucleus.enhancer.DataNucleusEnhancer.init(DataNucleusEnhancer.java:212) at org.datanucleus.enhancer.DataNucleusEnhancer.addClasses(DataNucleusEnhancer.java:370) at org.datanucleus.enhancer.EnhancerProcessor$EnhanceRunnable.run(EnhancerProcessor.java:163) at java.lang.Thread.run(Thread.java:636) I'm not sure why this is happening, since I have the following in my POM <dependency> <groupId>asm</groupId> <artifactId>asm</artifactId> <version>3.2</version> </dependency> Which is required by GAE, and the ASM jar is located in the target directory, so I'm failing to see what the issue is Any ideas?

• change the class loading order google app engine java

  - by Shekhar

  I am trying to create an application on google app engine using struts2. Struts2 internally uses freemarker .One of the Freemarker framework classes suppose X internally uses a class javax.swing.Treenode which is not in google app engine jre white list. Now in order to run my application i created a new class X in the same package structure as it was in freemarker framework and copied the class to WEB-INF classes.Then When i run my application it run fine. The problem is that i want to take out the class X from my application sourcecode and move it to newly created jar and place it in WEB-INF/lib folder. So that i can reuse the code in multiple project and my code remains clean of the freemarker code. But when i run the application it picks the old class X from the original freemarker framework.As a result i get ClassNotFoundException. Can anyone provide any help such that i can change the ClassLoading order such that my jar containing X class loads first.

• tomcat axis2 shared libs and spring destroy-method problem

  - by EugeneP

  in tomcat\lib there are axis*, axis2* jars. I cannot delete them [sysadmin won't allow to do that]. My web-app invokes web-services. I put Jax-ws jars directly to myapp/web-inf/lib. so inner calls frow a web app servlets use jax-ws libraries. but since "destroy-method" of the bean invokes a web-service, and session is destroyed, then spring makes a service call through tomcat/lib/* = axis2 libraries, and not by using web-inf/lib/jax-ws* How to: a) while not deleting axis2 libs from shared tomcat folder b) make spring use jax-ws libraries to make a web-service call ?

• ServletContext getResource not working

  - by David

  I'm trying to use ServletContext.getResource to retrieve a java.net.url reference to an image file (which I will then include in a PDF library using iText). When I use ServletContext.getRealPath("picture.jpg"), I get back a string URL. However, getResource always returns null. Example 1: String picture = ServletContext.getRealPath("picture.jpg"); // picture contains a non-null String with the correct path URL pictureURL = ServletContext.getResource(picture); // pictureURL is always null Example 2: URL pictureURL = ServletContext.getResource("picture.jpg"); // pictureURL is always null So what is the correct way to build a java.net.URL object pointing to a file in my webapps folder? Why does getRealPath work but not getResource? In case it helps at all, here is my folder structure webapps - mySite - picture.jpg Does my picture need to be stored in either WEB-INF or WEB-INF/classes to be read by getResource?

• java "File not found" when using commons-configuration XMLConfiguration with Tomcat

  - by Bruno Shine

  Hi all, I'm building two apps that uses commons-configuration XMLConfiguration. Since the apps are related, I've build another project, called commons, that has a custom configuration manager that initializes the XMLConfiguration like so: config = new XMLConfiguration("conf/config.xml"); What happens is that the "command-line" app works fine, loading the configuration file. But when I try to use my custom configuration manager on a webapp (using tomcat) I get a "org.apache.commons.configuration.ConfigurationException: Cannot locate configuration source". I've placed the conf directory on the WEB-INF folder, the root folder and the META-INF folder. I've also tried with "/conf/config.xml", "./conf/config.xml" and "../conf/config.xml". The only time I got this to work - on the web app - was using a absolute path. What am I missing? Thanks, Bruno

• Why is ContextConfiguration location different in idea and eclipse

  - by jakob

  Hello experts. In my team we work both in Eclipse and Idea. That works pretty good, except for one minor issue that I can't figure out how to solve. When setting the ContextConfiguration location in our tests and running them inside Eclipse everything works like a charm: @Test(groups = { "database" }) @ContextConfiguration(locations = {" file:src/main/webapp/WEB-INF/applicationContext.xml" }) But in my Idea env I get "could not find applicationContext" error. I need to set the location like this(project name is services): @Test(groups = { "database" }) @ContextConfiguration(locations = {" file:services/src/main/webapp/WEB-INF/applicationContext.xml" }) The project structure is like this: parent.pom with two child poms: services.pom and other.pom. When running the test in the terminal from the service project like this: mvn -Dtest=com.mytest.service.somepackage.TheTest test there are no issues. I guess that since my project structure is parent-with-two-children the need of /service is necessary(The project is created by pointing out the parent pom). Is there a way to fix this? Could you please help me with a solution. thx

• Spring MVC configuration problems

  - by Smek

  i have some problems with configuring Spring MVC. I made a maven multi module project with the following modules: /api /domain /repositories /webapp I like to share the domain and the repositories between the api and the webapp (both web projects). First i want to configure the webapp to use the repositories module so i added the dependencies in the xml file like this: <dependency> <groupId>${project.groupId}</groupId> <artifactId>domain</artifactId> <version>1.0-SNAPSHOT</version> </dependency> <dependency> <groupId>${project.groupId}</groupId> <artifactId>repositories</artifactId> <version>1.0-SNAPSHOT</version> </dependency> And my controller in the webapp module looks like this: package com.mywebapp.webapp; import com.mywebapp.domain.Person; import com.mywebapp.repositories.services.PersonService; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.context.annotation.ComponentScan; import org.springframework.context.annotation.Configuration; import org.springframework.stereotype.Controller; import org.springframework.ui.ModelMap; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RequestMethod; @Controller @RequestMapping("/") @Configuration @ComponentScan("com.mywebapp.repositories") public class PersonController { @Autowired PersonService personservice; @RequestMapping(method = RequestMethod.GET) public String printWelcome(ModelMap model) { Person p = new Person(); p.age = 23; p.firstName = "John"; p.lastName = "Doe"; personservice.createNewPerson(p); model.addAttribute("message", "Hello world!"); return "index"; } } In my webapp module i try to load configuration files in my web.xml like this: <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:/META-INF/persistence-context.xml, classpath:/META-INF/service-context.xml</param-value> </context-param> These files cannot be found so i get the following error: org.springframework.beans.factory.BeanDefinitionStoreException: IOException parsing XML document from class path resource [META-INF/persistence-context.xml]; nested exception is java.io.FileNotFoundException: class path resource [META-INF/persistence-context.xml] cannot be opened because it does not exist These files are in the repositories module so my first question is how can i make Spring to find these files? I also have trouble Autowiring the PersonService to my Controller class did i forget to configure something in my XML? Here is the error message: [INFO] [talledLocalContainer] SEVERE: Exception sending context initialized event to listener instance of class org.springframework.web.context.ContextLoaderListener [INFO] [talledLocalContainer] org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'personServiceImpl': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private com.mywebapp.repositories.repository.PersonRepository com.mywebapp.repositories.services.PersonServiceImpl.personRepository; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No matching bean of type [com.mywebapp.repositories.repository.PersonRepository] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency.

• Hibernate configuration files not found by Axis2

  - by DanJo519

  I am writing a web service to be deployed on Tomcat using Axis2. I am using Hibernate3 to persist data between the web service and a MySQL database. When running the application through by IDE, the method I am exposing through Axis2 works as intended, however when I deploy the .aar to Tomcat, I receive a SOAP Error claiming that hibernate.cfg.xml cannot be found. However, inside the .aar, I clearly see that all the configuration file and all the mapping files are included. I have determined a workaround: If I place the resulting files from the Netbeans build/class folder into the axis2/WEB-INF/class folder, then the application works as expected. My question, then, is is there a better way to deploy my application so that Axis2 will pick up the configuration and mapping files through the deployed .aar without my manually having to copy the contents of the build/class folder into the axis2/WEB-INF/class folder?

• How to select saxon TransformerFactory in Java

  - by pAkY88

  In my web application I need to use Saxon TransformerFactory to use XSLT 2.0 but I can't use setProperty method because I haven't this right on the web server and there is a Security Manager. So i have read that it's possible to do this: Use the Services API (as detailed in the JAR specification), if available, to determine the classname. The Services API will look for a classname in the file META-INF/services/javax.xml.transform.TransformerFactory in jars available to the runtime. I found this file in WEB-INF/lib/saxon9.jar but when I istantiate a TransformerFactory is always selected default factory and not saxon factory. How can I select Saxon Transformer Factory? Thanks

• Why does headless PDE Build omit directories I've specified in build.properties's bin.includes?

  - by Woody Zenfell III

  One of my Eclipse plug-ins (OSGi bundles) is supposed to contain a directory (Database Elements) of .sql files. My build.properties shows: bin.includes = META-INF/,\ .,\ Database Elements/ (...which looks right to me.) When I build and run from within my interactive Eclipse IDE, everything works fine: calls to Bundle.getEntry(String) and Bundle.findEntries(String, String, bool) return valid URL objects; my tests are happy; my code is happy. When I build via headless ant script (using PDE Build), those same calls end up returning null. My tests break; my code breaks. I find that Database Elements is quietly but simply missing from my plug-in's JAR package. (META-INF and the built classes still make it in there fine.) I scoured the build log (even eventually invoking ant -verbose on the relevant portion of the build script) but saw no mention of anything helpful. What gives?

• How should jruby-jars and jruby-rack be added to the classpath using warbler?

  - by Ben Hogan

  Hi again, I've been reading through the warbler source code, and I can't figure out how the jruby-jars and jruby-rack jars are meant to end up on the servlet classpath? It seems warbler is copying them into web-inf/gems/gems/<gemname>/lib/<jarname>.jar but they are not on the classpath. I'm guessing that if I put them in my ruby apps lib/ folder they would be copied to web-inf/lib and all would be well, however, it seems odd to have 2 copies of the jar in the war file, is that what I am meant to do?

• Getting a Spring resource

  - by Javi

  Hello, I'm trying to read a css file with the Resources provided by Spring. My application looks like this: src src/com herer my classes inside packages WebContent WebContent/resources/style/myCSS.css -- the css I want to read WebContent/WEB-INF -- here is my application-context.xml I can get the css and read it by doing something like this: UrlResource file = new UrlResource("http://localhost:8080/myApp/resources/style/myCSS.css"); but it depends on the server and aplication names. I've tried to do it by other implementations of Resource Interface, but the file is not found cause I can't find out how to wite the path. I've tried with this: FileSystemResource file = new FileSystemResource("/WebContent/resources/style/myCSS.css"); I also tried with wildcards, but it doesn't find the file either. ApplicationContext ctx = new FileSystemXmlApplicationContext("classpath*:/WEB-INF/application-context-core.xml"); Resource file = ctx.getResource("file:**/myCSS.css"); How should I write the path to get the css. Thanks.

• custom tag 'cannot be resolved to a type'

  - by lotus99t

  I have a custom tag, packaged into a library jar that is included in my web apps war file. I get the following error: An error occurred at line: 66 in the jsp file: /WEB-INF/jsp/portlet/portfolio/operations/operationsInfo.jsp org.apache.jsp.tag.meta.form.WidgetFactory_tag cannot be resolved to a type 63: <c:forEach var="fldCfg" items="${config.page.fields}" > 64: <tr> 65: <td><form:Label fld="${fldCfg}"/></td> 66: <td><form:WidgetFactory fld="${fldCfg}" decodesMap="${decodesMap}" command="${operationsInfoBean}" dateFormat="${preferredDateFormat}"/></td> 67: </tr> 68: </c:forEach> 69: </table> But it doesn't seem to complain about Label which is in the same taglib. I've confirmed that the jar is in the war and that the tag file is in the jar and the that the TLD (in META-INF) expressly defines 'WidgetFactory' Why am I getting this error?

• Can UMDF drivers be packaged/shipped via WiX?

  - by Rafael Rivera

  Howdy Internets: I put together a WiX 3.0 package, utilizing the DIFx extensions, with the intentions to install a Windows 7 Sensor (UMDF driver). During installation, DIFXAPP logged "No matching devices found in INF" and simply threw the driver into storage. I read I'm to populate my INF with an appropriate DriverPackageType, but according to MSDN's enumerated list, nothing fits. Is UMDF driver installation a supported scenario? If not, what's the best practice for using WiX to install such drivers? Disassembling the DIfx extension shows intent to support Co-installer packages, I have yet to try 3.5 beta.

• Logging with log4j on tomcat jruby-rack for a Rails 3 application

  - by John

  I just spent the better part of 3 hours trying to get my Rails application logging with Log4j. I've finally got it working, but I'm not sure if what I did is correct. I tried various methods to no avail until my various last attempt. So I'm really looking for some validation here, perhaps some pointers and tips as well -- anything would be appreciated to be honest. I've summarized all my feeble methods into three attempts below. I'm hoping for some enlightenment on where I went wrong with each attempt -- even if it means I get ripped up. Thanks for the help in advance! System Specs Rails 3.0 Windows Server 2008 Log4j 1.2 Tomact 6.0.29 Java 6 Attempt 1 - Configured Tomcat to Use Log4J I basically followed the guide on the Apache Tomcat website here. The steps are: Create a log4j.properties file in $CATALINA_HOME/lib Download and copy the log4j-x.y.z.jar into $CATALINA_HOME/lib Replace $CATALINA_HOME/bin/tomcat-juli.jar with the tomcat-juli.jar from the Apache Tomcat Extras folder Copy tomcat-juli-adapters.jar from the Apache Tomcat Extras folder into $CATALINA_HOME/lib Delete $CATALINA_BASE/conf/logging.properties Start Tomcat (as a service) Expected Results According to the Guide I should have seen a tomcat.log file in my $CATALINA_BASE/logs folder. Actual Results No tomcat.log Saw three of the standard logs instead jakarta_service_20101231.log stderr_20101231.log stdout_20101231.log Question Shouldn't I have at least seen a tomcat.log file? Attempt 2 - Use default Tomcat logging (commons-logging) Reverted all the changes from the previous setup Modified $CATALINA_BASE/conf/logging.properties by doing the following: Adding a setting for my application in the handlers line: 5rails3.org.apache.juli.FileHandler Adding Handler specific properties 5rails3.org.apache.juli.FileHandler.level = FINE 5rails3.org.apache.juli.FileHandler.directory = ${catalina.base}/logs 5rails3.org.apache.juli.FileHandler.prefix = rails3. Adding Facility specific properties org.apache.catalina.core.ContainerBase.[Catalina].[localhost].[/rails3].level = INFO org.apache.catalina.core.ContainerBase.[Catalina].[localhost].[/rails3].handlers = 4host-manager.org.apache.juli.FileHandler Modified my web.xml by adding the following context parameter as per the Logging section of the jruby-rack readme (I also modified my warbler.rb accordingly, but I did opted to change the web.xml directly to test things faster). <context-param> <param-name>jruby.rack.logging</param-name> <param-value>commons_logging</param-value> </context-param> Restarted Tomcat Results A log file was created (rails3.log), however there was no log information in the file. Attempt 2A - Use Log4j with existing set up I decided to go Log4j another whirl with this new web.xml setting. Copied the log4j.jar into my WEB-INF/lib folder Created a log4j.properties file and put it into WEB-INF/classes log4j.rootLogger=INFO, R log4j.logger.javax.servlet=DEBUG log4j.appender.R=org.apache.log4j.RollingFileAppender log4j.appender.R.File=${catalina.base}/logs/rails3.log log4j.appender.R.MaxFileSize=5036KB log4j.appender.R.MaxBackupIndex=4 log4j.appender.R.layout=org.apache.log4j.PatternLayout log4j.appender.R.layout.ConversionPattern=%d{dd MMM yyyy HH:mm:ss} [%t] %-5p %c %x - %m%n Restarted Tomcat Results Same as Attempt 2 NOTE: I used log4j.logger.javax.servlet=DEBUG because I read in the jruby-rack README that all logging output is automatically redirected to the javax.servlet.ServletContext#log method. So I though this would capture it. I was obviously wrong. Question Why didn't this work? Isn't Log4J using the commons_logging API? Attempt 3 - Tried out slf4j (WORKED) A bit uncertain as to why Attempt 2A didn't work, I thought to myself, maybe I can't use commons_logging for the jruby.rack.logging parameter because it's probably not using commons_logging API... (but I was still not sure). I saw slf4j as an option. I have never heard of it and by stroke of luck, I decided to look up what it is. After reading briefly about what it does, I thought it was good of a shot as any and decided to try it out following the instructions here. Continuing from the setup of Attempt 2A: Copied slf4j-api-1.6.1.jar and slf4j-simple-1.6.1.jar into my WEB-INF/lib folder I also copied slf4j-log4j12-1.6.1.jar into my WEB-INF/lib folder Restarted Tomcat And VIOLA! I now have logging information going into my rails3.log file. So the big question is: WTF? Even though logging seems to be working now, I'm really not sure if I did this right. So like I said earlier, I'm really looking for some validation more or less. I'd also appreciate any pointers/tips/advice if you have any. Thanks!

• How do you create a MANIFEST.MF that's available when you're testing and running from a jar in produ

  - by warvair

  I've spent far too much time trying to figure this out. This should be the simplest thing and everyone who distributes Java applications in jars must have to deal with it. I just want to know the proper way to add versioning to my Java app so that I can access the version information when I'm testing, e.g. debugging in Eclipse and running from a jar. Here's what I have in my build.xml: <target name="jar" depends = "compile"> <property name="version.num" value="1.0.0"/> <buildnumber file="build.num"/> <tstamp> <format property="TODAY" pattern="yyyy-MM-dd HH:mm:ss" /> </tstamp> <manifest file="${build}/META-INF/MANIFEST.MF"> <attribute name="Built-By" value="${user.name}" /> <attribute name="Built-Date" value="${TODAY}" /> <attribute name="Implementation-Title" value="MyApp" /> <attribute name="Implementation-Vendor" value="MyCompany" /> <attribute name="Implementation-Version" value="${version.num}-b${build.number}"/> </manifest> <jar destfile="${build}/myapp.jar" basedir="${build}" excludes="*.jar" /> </target> This creates /META-INF/MANIFEST.MF and I can read the values when I'm debugging in Eclipse thusly: public MyClass() { try { InputStream stream = getClass().getResourceAsStream("/META-INF/MANIFEST.MF"); Manifest manifest = new Manifest(stream); Attributes attributes = manifest.getMainAttributes(); String implementationTitle = attributes.getValue("Implementation-Title"); String implementationVersion = attributes.getValue("Implementation-Version"); String builtDate = attributes.getValue("Built-Date"); String builtBy = attributes.getValue("Built-By"); } catch (IOException e) { logger.error("Couldn't read manifest."); } } But, when I create the jar file, it loads the manifest of another jar (presumably the first jar loaded by the application - in my case, activation.jar). Also, the following code doesn't work either although all the proper values are in the manifest file. Package thisPackage = getClass().getPackage(); String implementationVersion = thisPackage.getImplementationVersion(); Any ideas?

• How to setup Main class in manifest file in jar produced by NetBeans project

  - by Leni Kirilov

  I have the following problem. I have a Java project in my NetBeans IDE 6.8. When I compile it and it produces a .jar file containing everything possible, the META-INF is not right. It doesn't contain the class to be executed - with main() method. When I click the Run button inside the IDE, everything works. The settings of the project are also set the right way - pointing to a class in my project. I tried adding a folder META-INF with manifest file but I didn't manage. Is there a way to do this manually in NetBeans, because I found that if I add the missing Main class in the manifest, everything works.

• Deploying backing bean with composite component in separate jar

  - by Checkoff

  I have some difficulties deploying my web app on JBoss AS 6.1. My current Project is separated into the main web app (controller/managed beans & web frontend using JSF 2 facelets) and one jar with the composite components + backing beans. But when I try to access the page I got an error that the specified component type could not be instantiated. Copying the backing bean into the main web app solves the problem, but this isn't what I want. So is there anything to pay attention to? The backing bean looks like @FacesComponent(value = "elementBase") public class ElementBase extends UINamingContainer { ... } and the composite components interface <composite:interface componentType="elementBase"> ... some attributes </composite:interface> The structure of the jar is the following -- META-INF |-- resources | |-- components | |-- elementBase.xhtml -- com |-- example | |-- ElementBase.class I've also tried to add faces-config.xml within META-INF folder, with the component type, but the component type was still not found.
