I need to create a Hook to inject Javascript in a site. I have not had troubles creating hook but when I deploy it, my hook is not registered like Hook.
I have tried to deploy it with Liferay and Tomcat and this work fine.
Anybody knows what could be happenning?
Thanks in advance.
I'm sorry to say that Liferay's hook mechanism doesn't fully work in JBoss domain mode. The Liferay documentation says:
"...since Liferay’s JSP override mechanism relies on the application
server reloading customized JSP files from the exploded plugin .war
file location. Other plugins, such as service or action hooks, should
still work properly since they don’t require JBoss to access anything
(such as JSP files) from an exploded .war file on the file system..."
I suggest, if you can, to change to JBoss standalone mode or change to other application server like Tomcat that is fully supported by Liferay.
You can read more information about that in installing-liferay-on-jboss

I am creating a Static Web Project using Eclipse Juno Service Release 2.
My problem is that I have an HTML file (very simple, created automatically with Eclipse with HTML5 template) in this project and I would run it in an external browser (for example, Chrome) using as Server JBoss 7.1.
I have already configured properly JBoss in Eclipse, I can run/stop it without problems.
I have configured as Web Browser Chrome.
I don't know how run the single html file in my localhost:8080.
Someone can help me?
If you have created the project then you would have to deploy it.
Refer to http://www.mastertheboss.com/eclipse/jboss-eclipse/jboss-and-eclipse?showall=&start=1 which describes how to deploy an application.
And your URL to the file would be http://localhost:8080/yourProjectName/htmlFileName
Example: http://localhost:8080/TestApp/index.html
I am newbie with jboss-eclipse. I have to work on javaEE5 with JBoss AS 5.1.0.GA. I don't want to use JRebel at the moment.
I installed "Eclipse Java EE IDE" with "JBoss Tools". I added the JBoss 5.1 Runtime server on eclipse and added a new ear project with :
an EJB3.0 class in ejb project;
a javabean class and index.jsp in web project.
I noticed when I make a modification in the jsp file, I can see instantly the changes after refreshing the web browser. That's ok.
When I modify EJB and javabean classes, there is no instant hot deployment. I have to restart the ear application (without restrating jboss server) or "full publish" the ear via eclipse to see changes.
Is there any way to have instant hot deployement for EJB and javabeans?
PS: I tried "incremental" publish but it hasn't worked.
Thank you!
You do need 3rd party tools for that, the most notable being JRebel. Without advertising I have to say this tool has saved me lots and lots of hours already while developing EE applications.
In jboss AS 7.1.1 you just have to go to the as admin console at localhost:9990 and select: Profile -> Core -> Deployment Scanners -> Auto-Deploy Exploded . You might also want to change the scan interval to something smaller. Afterwards, you may deploy your application for the first time by selecting "Run on Server". From this time on, your application will get automatically deployed whenever you change a file and it manages to compile.
I do not know if Jboss 5.1 has this feature, and if I were you I'd consider using 7.1.1 for development when it does not have it.
The hot deployment works fine with JBoss when publishing new files in your deploy folder, only class exchange will not happen in your currently deployed application.
That's why you see changes to all static content like HTML files immediately, but not changes to your java code.
In order to do activate them, you'll have to restart your application (not the whole JBoss, only your application, done for example in JBoss server view).
I have no practical experience with JRebel and I do believe that it saves you time, but you have to be careful with such tools, as they can introduce new problems which you spend much times in debugging, ending up in restarting the container and everything works fine.
I have just switched to Intellij Idea (11) and I'm having possibly simple problem for which I cannot find a solution within Intellij IDE. I have a web application which contains some classes marked with annotations from javax.ws.rs like eg. #Path("/members") etc and my web.xml file configured for handling REST calls.
The application is build with Maven, when I package the application either from command line or through the Intellij IDE and copy the .war file into tomcat webapps directory manually, all works fine, eg. I can access GET based services from the browser.
If I deploy the application through configured tomcat in Intellij IDE the application works but without the REST portion, so I'm not able to execute any rest based calls (all end up with 404 error). I cannot see anything in logs about deploying rest service classes like I do during manual deployment:
INFO: Adding scanned resource: com.softberries.klerk.rest.MemberResourceRESTService
so its definitively an IDE configuration option I've missed which prevents tomcat from scanning classes for this annotations.
The question is how should I configure my Tomcat within the IDE to work the same as started manually.
with Intellij you need to expose the classes as web services from Tools > WebServices.
Also check that in Setting > Web Services, the prefix path for web service is correct (by default is /services).
Here you have a nice tutorial about how to create webservices in intellij.
http://www.academia.edu/4526516/Creating_Web_Services_Applications_with_IntelliJ_IDEA
By the way... when you do a deploy from intellij, the application goes to:
C:\Users\userName.IntelliJIdea10\system\tomcat\NameDeploy"
This info appears in the console as: "Using CATALINA_BASE": .../path...
Hope this helps,
Cheers
When I develop an Axis2 web service on Eclipse, I noticed that Eclipse is automatically copying the classes from the lib folder of Axis2 to the lib folder of the new project. However, not all classes from the lib folder of Axis2 are being copied. Interestingly, the web service runs without any problem when deployed to Tomcat via Eclipse even if some the jars from Axis2 were not copied. Also, when I viewed the temp file of Tomcat, Tomcat seems to generate the jars for the listed modules on modules.list of the web service.
Can someone enlighten me regarding what is happening on this? Why Eclipse doesn't copy all the jars from Axis2? Why can the web service run on Tomcat even without the other jars from Axis2? What are those temp files for? When and why is it being generated?
I tried to run the same project on WebSphere and I am encountering a ClassDefNotFound exception because of the missing jars. My problem was solved when I copied all the Axis2 jars that was not copied by Eclipse to my project. But I'm not comfortable with my solution because Tomcat can run my project even without those jars. Is my solution really the right solution? Or am I missing a configuration setting?
This is just for clarification:
My web service is already running in Axis2. My class loading policy is set to PARENT_LAST. I know that since WebSphere has its own Axis2 configuration, the class loading policy must be set to PARENT_LAST so that WebSphere will use the Axis2 from the project itself. Aside from setting the class loading policy, I did something to make my web service run on WebSphere. I describe what I did above. My question is why such method must be taken?
WebSphere has it's own axis2 configuration as part of its Java EE server spec for JAX-WS. Change your class loading policy to PARENT_LAST and check if that solves your problem.
Edit:
As the original post already states: WebSphere is a Java EE server depending on version it supports its the standard Java JAX-WS web services. Actually web services became part of the standard jdk.
If you use JAX-WS like mentioned in Introduction to JAX-WS or building web services then you don't have to add any 3rd party library for getting your web services running. As soon as you use the non JDK implementation like axis2 you have to package it with your application.
IBM didn't just pack the axis2 into their WAS/JDK, they modified it. I'm not sure what Tomcat delivers, however as long as you use JAX-WS it shouldn't matter. With JAX-WS you don't have any direct import of the org.apache.axis packages. If you use these imports you have to supply the libraries and make sure that yours are loaded.
I want to run a servlet in Eclipse. For this I have created a dynamic web project and I have deployed my servlet.java file under the WEB-INF folder. I have also added the servlet.jar file. How can I run the file as a java application?
Servlets run in a servletcontainer. Servlets are not "plain vanilla" java applications. See, they do not have a main() method! Servlets listens on HTTP requests and returns HTTP responses through the network. Running the sole servlet class as a plain vanilla Java application doesn't automagically make them to listen and react on HTTP requests.
Apache Tomcat is a popular servletcontainer. Just download and unzip it. Then in Eclipse (I assume that you already have downloaded the Eclipse Java EE version, else drop it all together and redownload the right version), go to Servers view and add the newly installed Tomcat instance. Then create a Dynamic Web Project wherein you pick the newly integrated server instance from the list. Eclipse will then automatically take the Servlet API libraries in the classpath/buildpath (thus, you do NOT need to download a random "servlet.jar file" separately yourself! this is only receipt for major trouble). Then create a Servlet class and register it in web.xml. Then deploy the project to the newly integrated server and start it. Then in your favourite webbrowser go to http://hostname:port/contextname which is usually http://localhost:8080/webprojectname.
To learn more about servlets (and Eclipse and Tomcat) I strongly recommend you to go through those tutorials. You can also search on youtube for video tutorials using the obvious keywords.
Servlets run in servlet/JSP engines, like Tomcat or Resin or Jetty. You normally don't run them outside a container.
You can certainly deploy your app to a servlet/JSP engine and start in from Eclipse. But it's the app server that you run, which then acts as the home for your servlet.
Servlets cannot be run directly as an Java app.
I recommend two approaches:
Refactor your servlet and put your "java" code (what ever generic code you want to call) in another jar that you call from both the servlet and the Java application.
Run the servlet in a container in Eclipse. See http://www.eclipse.org/jetty/
Communicate with the servlet through HttpRequest's and HttpResponse's
