  • if a JAR is placed on app servers's classpath how do we reference it from JSP

    - by Omnipresent
    On our application we are getting an error saying: PWC6117: File "/struts-tags" not found code in the file thats giving error is: <%@ taglib prefix="s" uri="/struts-tags" %> This file is in struts2-core.jar which is placed on the classpath of the app server (Sun 9.1). The code will work fine and not complain when the jar is actually in WEB-INF/lib of the application, compared to being on classpath of the appserver. But we can not change that. it has to be on appservers classpath. But how should we change our code so that this error goes away? I can create mapping in my web.xml so that tag uri's are change. but what should taglib-location be changed to? so that it references to app servers classpath? <taglib> <taglib-uri>/WEB-INF/struts-tags.tld</taglib-uri> <taglib-location>/WEB-INF/struts-tags.tld</taglib-location> </taglib>

  • Setting freemarker template from classpath

    - by wuntee
    I have a web application that I need to manually obtain a Freemarker template - the template is obtained via a class in a library project, but the actual tpl file is contained in the web application classpath. So, there are 2 projects, one 'taac-backend-api' and another 'taac-web'; taac-backend-api has the code to grab the template, and process it, but taac-web is where the template is stores (specifically in: WEB-INF/classes/email/vendor.tpl) - I have tried everything from using springs classpath resource to using Freemarkers setClassForTemplateLoading method. I assume this would work: freemarkerConfiguration = new Configuration(); freemarkerConfiguration.setClassForTemplateLoading(this.getClass(), ""); Template freemarkerTemplate = freemarkerConfiguration.getTemplate("/email/vendor.tpl"); yet, I always get a FileNotFoundException. Can someone explain the best way to obtain a template from the classpath? Thanks.

  • PATH and CLASSPATH in Windows7 7 / Eclipse

    - by Richard Knop
    So I would like to set PATH and CLASSPATH system variables so I can use javac and java commands in the command line. I can just compile and run java programs in eclipse but I would also like to be able to run them through command line. This is where I have Java installed: C:\Program Files (x86)\Java jdk1.6.0_20 jre6 And this is where eclipse stores my Java projects: D:\java-projects HelloWorld bin HelloWorld.class src HelloWorld.java I have set up the PATH and CLASSPATH variables like this: PATH: C:\Program Files (x86)\Java\jdk1.6.0_20\bin CLASSPATH: D:\java-projects But it doesn't work. When I write: java HelloWorld Or: java HelloWorld.class I get error like this: Exception in thread “main” java.lang.NoClassDefFoundError: HelloWorld The error is longer, that's just the first line. How can I fix this? I'm mainly interested to be able to run compiled .class programs from the command line, I can do compiling in the eclipse.

  • What's in an Eclipse .classpath/.project file?

    - by totalEclipse
    We recently had an issue with an Eclipse project for one of our team members. Tomcat was not deploying JARs of the application. We eventually noticed the .classpath Eclipse file was not the same as for the team members where the project was OK. We replaced the .classpath file with one from a project that was OK and the Tomcat deploy was complete. Just out of curiosity and to know at what to look in the future if something is wrong, what is inside the .classpath and .project files. What can I add in there, what does it all mean?

  • Yet another Java classpath problem

    - by pypmannetjies
    Hi I've been working on a project in Netbeans. Now I'd like to submit it and allow the markers to compile it with a script. However, I get the NoClassDefFoundError when I try to run via the command line. Even when setting the classpath to the current directory manually. javac Main.java works fine then calling java -classpath . Main gives: java -classpath .

  • Setting CLASSPATH during runtime IKVM

    - by Ciddan
    How do I set a CLASSPATH variable during runtime while using IKVM? I've been trying to do it by using: java.lang.System.setProperty("java.class.path", "whatever"); The class I'm calling requires a configuration file in the classpath to work - and I keep getting errors that seem to indicate that it hasn't gotten its settings. Is the way I'm trying to add variable incorrect?

  • red5 Install on Ubuntu 10.04? Problems with libslf4j

    - by mrgordon
    I've been trying for many days to get Red5 to install on Ubuntu 10.04. I finally managed to get red5.sh to stop hanging a few seconds in but now I'm getting the following error: Setting default logging context: default Exception in thread "main" java.lang.reflect.InvocationTargetException at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at org.red5.server.Bootstrap.bootStrap(Bootstrap.java:135) at org.red5.server.Bootstrap.main(Bootstrap.java:50) Caused by: java.lang.NoSuchMethodError: org.slf4j.impl.StaticLoggerBinder.getContextSelector()Lch/qos/logback/classic/selector/ContextSelector; at org.red5.logging.Red5LoggerFactory.getLogger(Red5LoggerFactory.java:121) at org.red5.logging.Red5LoggerFactory.getLogger(Red5LoggerFactory.java:108) at org.red5.server.Launcher.launch(Launcher.java:51) ... 6 more I suspected that this had to do with slf4j not being installed or on my classpath. I installed logback and libslf4j-java from aptitude and I see related files in my red5 lib directories. For example: /usr/share/red5/lib/slf4j-api-1.6.1.jar /usr/share/red5/lib/log4j-over-slf4j-1.6.1.jar /usr/share/red5/lib/logback-classic-0.9.26.jar /usr/share/red5/lib/logback-core-0.9.26.jar /usr/share/red5/lib/jcl-over-slf4j-1.6.1.jar /usr/share/red5/lib/jul-to-slf4j-1.6.1.jar And I set my classpath to /usr/share/red5/lib/ Any ideas on where to proceed from here? There seem to be a lot of people having trouble getting 10.04 and red5 0.9 working together. I've tried red5-0.9.1.tar.gz and red5_0.9.0-RC1_all.deb. The libraries above should be all that are needed according to Red5's documentation and I got the latest version of each.

  • Spring Roo unable to generate Selenium tests because of Xerces error

    - by Wraith
    After watching Roo Google IO, I decided to try it out using this tutorial, but I'm getting stuck when trying to create Selenium tests. ~.web roo> selenium test --controller ~.web.PizzaOrderController Created SRC_MAIN_WEBAPP/selenium Created SRC_MAIN_WEBAPP/selenium/test-pizzaorder.xhtml Created SRC_MAIN_WEBAPP/selenium/test-suite.xhtml Undo create SRC_MAIN_WEBAPP/selenium/test-suite.xhtml Undo create SRC_MAIN_WEBAPP/selenium/test-pizzaorder.xhtml Undo create SRC_MAIN_WEBAPP/selenium com.sun.org.apache.xerces.internal.dom.DeferredCommentImpl cannot be cast to org.w3c.dom.Element A person at this forum suggested removing Xerces from the classpath because Java 6 has its own XML parser based on Xerces. However, I haven't come across a clear way to remove something from the classpath, only setting it (which I think would be tedious each time). Does anyone know of a clear way to remove jars from the classpath? Has anyone encountered this Roo problem before and solved it another way?

  • How can I get Hudson to be able to access JUnit?

    - by Bedwyr Humphreys
    I've got Hudson running on TOMCAT, it can build my Netbeans project using the ant build.xml, but it won't run any of my unit tests because of what I assume is a problem with the classpath: package org.junit does not exist [javac] import org.junit.After; [javac] ^ But I've got the junit-4.8.1.jar on the classpath in /etc/environment and I can successfuly run the junit tests from a console using java org.junit.runner.JUnitCore org.junit.tests.AllTests My CLASSPATH is set to /home/bedwyr/junit4.8.1/junit-4.8.1.jar:. Am I going wrong somewhere or is there anything else I need to set? [edit] What I did was to export/include (using the ide) all libraries (including Junit) hudson then reads all it needs from the subversion repo. I then ran into an issue with exposing hudson to the internet, and pretty soon gave up on tomcat on ubuntu server (again, to do with the tomcat security manager) - glassfish is a lot smoother and that's where I am now - apache front end with ajp_proxy to hudson on glassfish.

  • What's the diffrence btw System property and system environment variable

    - by khue
    Hi all I am not clear about this. When I run a java App or run an Applet in applet viewer,( in the IDE environment), System.getProperty("java.class.path") give me the same as System.getenv("CLASSPATH"), which is the CLASSPATH env variable defined. But when I deploy my applet to webserver and access it from the same computer as a client, I get different result for the two (System.getProperty("java.class.path") only point to jre home and System.getenv("CLASSPATH") return null). And here is some other things that make me wonder: For the applet part, the env var JAVA_HOME, i get the same result when deploying the applet in a browser as well as Applet Viewer. And if I define myself a env variable at system level, and use getenv("envName") the result is null. Is there anyway I can define one and get it in my java program? Thanks a lot Regards K.

  • List of dependency jar files in Maven

    - by Sindri Traustason
    Using Maven 2, is there a way I can list out the jar dependencies as just the file names? mvn dependency:build-classpath can list the jar files, but that will include the full path to their location in my local repository. What I need is essentially just a list of the file names (or the file names that the copy-dependencies goal copied). So the list I need would be something like activation-1.1.jar,antlr-2.7.6.jar,aopalliance-1.0.jar etc... ideally as a maven property, but I guess, a file such as build-classpath can generate will do. What I am trying to achieve is writing a Bundle-ClassPath to an otherwise manually maintained MANIFEST.MF file for a OSGi bundle. (You shouldn't need to understand this bit to answer the question.) To clarify: The question is not about how to write manifest headers into the MANIFEST.MF file in a jar (that is easily googleble). I am asking about how to get the data I want to write, namely the list shown above.

  • Should all resources in a java web application be uniquely named?

    - by morgancodes
    Trying to understand resources in java-land. I believe the following is true: Resources loaded via the classpath have no namespace, they only have a file name. It's wisest to always load resources via the classpath, never via the file system, even in unit tests. Therefore, resources must always have unique file names, or collisions will occur. Are there flaws in my assumptions or my conclusion?

  • Is it correct or incorrect for a Java JAR to contain its own dependencies?

    - by 4herpsand7derpsago
    I guess this is a two-part question. I am trying to write my own Ant task (MyFirstTask) that can be used in other project's build.xml buildfiles. To do this, I need to compile and package my Ant task inside its own JAR. Because this Ant task that I have written is fairly complicated, it has about 20 dependencies (other JAR files), such as using XStream for OX-mapping, Guice for DI, etc. I am currently writing the package task in the build.xml file inside the MyFirstTask project (the buildfile that will package myfirsttask.jar, which is the reusable Ant task). I am suddenly realizing that I don't fully understand the intention of a Java JAR. Is it that a JAR should not contain dependencies, and leave it to the runtime configuration (the app container, the runtime environment, etc.) to supply it with the dependencies it needs? I would assume if this is the case, an executable JAR is an exception to the rule, yes? Or, is it the intention for Java JARs to also include their dependencies? Either way, I don't want to be forcing my users to be copying-n-pasting 25+ JARs into their Ant libs; that's just cruel. I like the way WAR files are set up, where the classpath for dependencies is defined under the classes/ directory. I guess, ultimately, I'd like my JAR structure to look like: myfirsttask.jar/ com/ --> the root package of my compiled binaries config/ --> config files, XML, XSD, etc. classes/ --> all dependencies, guice-3.0.jar, xstream-1.4.3.jar, etc. META-INF/ MANIFEST.MF I assume that in order to accomplish this (and get the runtime classpath to also look into the classes/ directory), I'll need to modify the MANIFEST.MF somehow (I know there's a manifest attribute called ClassPath, I believe?). I'm just having a tough time putting everything together, and have a looming/lingering question about the very intent of JARs to begin with. Can someone please confirm whether Oracle intends for JARs to contain their dependencies or not? And, either way, what I would have to do in the manifest (or anywhere else) to make sure that, at runtime, the classpath can find the dependencies stored under the classes/ directory? Thanks in advance!

  • Fail to launch application (CreateProcess error=87), can't use shorten classpath workaround

    When I launch our application in Eclipse on Windows I receive the following error: Exception occured executing command line. Cannot run program .. : CreateProcess error=87, The parameter is incorrect I've solved this in the past by shortening the CLASSPATH. I've now come to a point where I can no longer shorten the CLASSPATH, and would like to know if there are any other workarounds. http://support.microsoft.com/kb/830473 seems to indicate that the max command prompt line length in windows xp is 8191 characters, and the only solution is to shorten folder names, reduce depth of folder trees, using parameter files, etc.

  • Managing Data Dependecies of Java Classes that Load Data from the Classpath at Runtime

    - by Martin Potthast
    What is the simplest way to manage dependencies of Java classes to data files present in the classpath? More specifically: How should data dependencies be annotated? Perhaps using Java annotations (e.g., @Data)? Or rather some build entries in a build script or a properties file? Is there build tool that integrates and evaluates such information (Ant, Scons, ...)? Do you have examples? Consider the following scenario: A few lines of Ant create a Jar from my sources that includes everything found on the classpath. Then jarjar is used to remove all .class files that are not necessary to execute, say, class Foo. The problem is that all the data files that class Bar depends upon are still there in the Jar. The ideal deployment script, however, would recognize that the data files on which only class Bar depends can be removed while data files on which class Foo depends must be retained. Any hints?

  • setting java classpath for Libre Office Base in Fedora 16

    - by foampile
    using Fedora 16 OS. i want to use Libre Office Base to connect to MySQL. when i set up the JDBC connection, it asks me for the driver, however, it cannot be loaded (because it doesn't see it in the classpath). does anybody know how to set the classpath for Libre Office? is there like a config util tool for that? e.g. my driver is [B]com.mysql.jdbc.Driver [/B]situated in[B] /usr/share/java/mysql-connector-java-5.1.17.jar[/B]. it works fine when i connect from other JDBC clients, like straight Java or Eclipse Quantum plugin. the problem is that Libre Office does not ask me for the (class)path of where it can find the driver and i do not know where and how to set it so that it becomes visible. thanks

  • Specifiy classpath for maven

    - by Zombies
    Quite new to maven here so let me explain first what I am trying to do: We have certain JAR files which will not be added to the repo. This is because they are specific to Oracle ADF and are already placed on our application server. There is only 1 version to be used for all apps at anyone time. In order to compile though, we need to have these on the class path. There are a LOT of these JARS, so if we were to upgrade to a newer version of ADF, we would have to go into every application and redefine some pretty redundant dependencies. So again, my goal is to just add these JARs to the classpath, since we will control what version is actually used elsewhere. So basically, I want to just add every JAR in a given directory to maven's classpath for when it compiles. And without putting any of these JAR files in a repository. And of course, these JARs are not to be packaged into any EAR/WAR.

  • Self-modify the classpath within a Scala script?

    - by Alex R
    I'm trying to replace a bunch of Linux shell scripts with Scala scripts. One of the remaining challenges is how to scan an entire directory of JARs and place them into the classpath. Currently this is done in the shell script prior to invoking the scala JVM. I'd like to eliminate the shell script completely. Is there an elegant scala idiom for this? I have found this other question but in Java it seems hardly worthwhile to mess with it: http://stackoverflow.com/questions/252893/how-do-you-change-the-classpath-within-java

  • Should app config files be in jboss/bin directory?

    - by djangofan
    I am a Integration Engineer for a software company. My development team has generated various jboss .ear applications that rely on configuration files being in the jboss/bin directory and setting the CLASSPATH externally using batch files (on Windows from an external LIB directory) rather than using jboss's internally loaded classes. Is this the right/standard way of doing things? Would some other location be better (for the config files) such as jboss/server/instancename/deploy or some other directory? Any opinons on how I can direct my development team to doing things in a best practices fashion?

  • Jar not found when executing class

    - by Simon
    Hi there, I'm working through the ANTLR book and there are many examples that should be easy to compile using the command line. Some information to get te problem: antlr-3.2.jar contains the ANTLR classes. I added the antlr-3.2.jar to the CLASSPATH environment variable (Windows 7) and when compiling the classes with javac everything works fine. This is what i execute to compile my program: javac Test.java ExprLexer.java ExprParser.java Test.java contains my main()-method whereas ExprLexer and ExprParser are generated by ANTLR. All three classes use classes contained in the antlr-3.2.jar. But so far so good. As I just said, compiling works fine. It's when I try to execute the Test.class that I get trouble. This is what I type: java -cp ./ Test When executing this, the interpreter tells me that he can't find the ANTLR-classes contained in the antlr-3.2.jar, altough I added an entry in the CLASSPATH variable. E:\simone\Programmierung\Language Processing Tools\ANTLR\Book Samples and Exercises\Exercise\1\output\Test.java Exception in thread "main" java.lang.NoClassDefFoundError: org/antlr/runtime/Cha rStream Caused by: java.lang.ClassNotFoundException: org.antlr.runtime.CharStream at java.net.URLClassLoader$1.run(URLClassLoader.java:202) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:190) at java.lang.ClassLoader.loadClass(ClassLoader.java:307) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:301) at java.lang.ClassLoader.loadClass(ClassLoader.java:248) Could not find the main class: Test. Program will exit. I'm using Windows 7 and Java 1.6_20. Can someone tell what is going on? Why will the interpreter not look in the jar-Archive I specified in the CLASSPATH? I found some kind of workaroud. I copied the antlr-3.2.jar into the directory where the Test.class is located and then executed: java -cp ./;antlr-3.2.jar Test This worked out. But I don't want to type the jar-Archive everytime I execute my test programs. Is there a possibility to tell the interpreter that he should automatically look into the archive?
