I'm happy that netbeans 9.0 has just launched, but I can't create a Maven Web Application project in netbeans 9.0.
There is no Web Application option to select in Maven category when creating a new project.
I checked this post, but there is no available plugin for Java EE.
I have Java 10 enabled system wide.
Before netbeans 9.0, I was using netbeans 8.2 with Java 8 and had no problem.
For me, this is a big issue with Netbeans 9 and 10, but this is a way to handler for now:
Go to Tools > Plugins > Settings
Active Netbeans 8.2 Plugin
Portal
Wait for download content.
Then go to Available Plugins Tab.
Press Check for Newest
Search for web or EE
Check Install box for Java EE
Press Install
Restart IDE.
Yeah... we done!

Newly installed Netbeans 8.0 does not recognize my projects previously build in Netbeans v6.9.1. How do you import these?
Do you have old projects in some folder?
Copy this projects to C:\Users\User\Documents\NetBeansProjects
In Netbeans File/Open Project
Select your project
It looks like you've installed the NetBeans for Java SE without NetBeans for Java EE. You need the NetBeans for Java EE bundle (second column from the left) for all the web projects.
In my case I was using Java EE in one project, PHP and Zend in another. These projects needed plugins to work. I went to
NetBeans -> File -> Open Project
and my projects were listed even though they didn't show up in the Projects file browser. Each project's name was
<unrecognized project; missing plug-in?>
so I went to
NetBeans -> Tools -> Plugins
there I installed PHP, Zend and Java EE. I restarted NetBeans and everything worked fine.
This thread was useful to me:
http://forums.netbeans.org/ntopic17656.html
Once, I tried to install the Java SE Download bundles for Netbeans ( Was like mistake in clicking the Download option) but I was suppose to go for Java EE. SO, I was facing problem to import my previous Java EE Netbeans Project since I was in JavaSE Environment. Maybe Importing plugins for Java EE /Web or few more configuration would work for
that case but I was seriously stuck for a long time.
The Error was like :
<unrecognized project; missing plug-in?>
So, What I did was simply uninstalling Java SE Netbeans and installing Java EE one and my older project was easily imported. So, seriously you might need to care about the download bundles or the installed plugins but Netbeans is mostly good for importing / Exporting.
EDIT 2014-02-07: Eclipse Luna is here, and support for Tomcat 8 is included in the bundled WTP : ) Happy days!
Tomcat 8 is still in development, but you can get it here. Now there is a RC version on the main Apache Tomcat page. Update 2/27/14: 8 is released now, and adapters built for WTP, just not integrated into eclipse bundles yet. Soon!
In Eclipse Kepler though, there is no supported adapter in the add server list for Tomcat 8. the Tomcat 7 adapter doesn't work, and it doesn't look like there's a new extension for it to download in the "Install new Extension" dialog.
Is my only option to get it (Tomcat 8) running locally outside of Eclipse and maybe hook a remote debugger into it for stepping through code? Will that even work for Eclipse Kepler + Tomcat 8? IntelliJ IDEA 12 couldn't do it in the 30 minutes of time I put into that path.
If you're wondering why I'm trying to do this at all, I'm playing around with Spring 4.0.0.M1 and 4.0.0.M2 WebSocket stuff. They (per Rossen Stoyanchev's Spring 4.0 blog post and examples) use JSR-356, which is implemented in Tomcat 8, theoretically to be back-ported at some point to Tomcat 7.
An answer to the broader question of "How can I easily get a development environment going for Spring 4 WebSocket support?" would be nice, but it would also still be nice to know how to plug in unsupported web servers to Eclipse.
Cheers,
E
**Update 8/7/13 - Rossen Stoyanchev updated the Spring 4.0.0.M2 blog and added some jpda wisdom and shared that yeah, he's using remote debugging:
That said, it's not very hard to debug with Tomcat 8 inside Eclipse. Just change the last line in bin/startup.sh to be (note the addition of "jpda"):
exec "$PRGDIR"/"$EXECUTABLE" jpda start "$#"
Inside Eclipse create a remote debugging configuration for localhost port 80, launch it after starting Tomcat, and you can put breakpoints in the source code.
Thanks Rossen!
**Update 9/29/13 - Eclipse Kepler SR1 just arrived, but alas! No WTP support for Tomcat 8. Tomcat 8 is up to RC3.
**Updates 12/5/13
Blog url fix.
Tomcat 8 up to RC5.
Bug to track WTP fix in Eclipse to support Tomcat 8 HERE.
IntelliJ IDEA new version 13 says it now supports Tomcat 8. Haven't tried yet personally.
UPDATE: Eclipse Mars EE and later have native support for Tomcat8. Use this only if you have an earlier version of eclipse.
The latest version of Eclipse still does not support Tomcat 8, but you can add the new version of WTP and Tomcat 8 support will be added natively. To do this:
Download the latest version of Eclipse for Java EE
Go to the WTP downloads page, select the latest version (currently 3.6), and download the zip (under
Traditional Zip Files...Web App Developers). Here's the current link.
Copy the all of the files in features and plugins directories of the downloaded WTP into the corresponding Eclipse directories in your Eclipse folder (overwriting the existing files).
Start Eclipse and you should have a Tomcat 8 option available when you go to deploy.
I follow Jason's step, but not works.
And then I find the WTP Update site http://download.eclipse.org/webtools/updates/.
Help -> Install new software -> Add > WTP:http://download.eclipse.org/webtools/updates/ -> OK
Then Help -> Check for update, just works, I don't know whether Jason's affect this .
The only thing the eclipse plugin is checking is the tomcat version inside:
catalina.jar!/org/apache/catalina/util/ServerInfo.properties
I replaced the properties file with the one in tomcat7 and that fixed the issue for eclipse
In order to be able to deploy the spring-websockets sample app you need to edit the following file in eclipse:
.settings/org.eclipse.wst.common.project.facet.core.xml
And change the web version to 2.5
<installed facet="jst.web" version="2.5"/>
This should be a comment under the accepted answer, but I don't have 50 reputation yet.
At http://download.eclipse.org/webtools/downloads/
I first selected Released 3.5.2, which like others did not work for me.
Then I picked Integration 3.6.0, and saw Tomcat 8 for New Project of Dynamic Web Project.
I have tried below and it worked for me.
In eclipse go to Help->Eclipse Marketplace
Type JST extension in search box.
Install JSP Adapters for Luna
Restart the eclispe
You should be able to see Tocmat 8 server while adding new server.
In addition to #Jason's answer I had to do a bit more to get my app to run.
Download & unzip Eclipse IDE for Java EE Developers (Note the EE edition)
Download & unzip Eclipse's Web Tools Platform Stable (Milestone) 3.6+
Overwrite the two folders in the Eclipse IDE, with the WTP folder(s) (features & plugins folders)
Download and unzip Tomcat 8
In eclipse new -> other -> server -> Tomcat 8 (choose the unzipped location)
If you get a 404, click the Tomcat 8 in the Servers view -> Server Locations -> Change to Use Tomcat installation, and change the Deploy path: to webapps *
(If you can't edit this, delete any published webapps)
To add the Tomcat 9.0 (Tomcat build from the trunk) as a server in Eclipse.
Update the ServerInfo.properties file properties as below.
server.info=Apache Tomcat/#VERSION#
server.number=#VERSION_NUMBER#
server.built=#VERSION_BUILT#
server.info=Apache Tomcat/7.0.57
server.number=7.0.57.0
server.built=Nov 3 2014 08:39:16 UTC
Build the tomcat server from trunk and add the server as tomcat7 instance in Eclipse.
ServerInfo.properties file location : \tomcat\java\org\apache\catalina\util\ServerInfo.properties
The latest version of Springsource STS (3.6) supports Tomcat 8. It is based on eclipse Luna 4.4 and supports Java 8. Have at it!
Alternatively we can use eclipse update site (Help -> Install New Features -> Add Site (urls below) -> Select desired Features).
For Luna: http://download.eclipse.org/webtools/repository/luna
For Kepler: http://download.eclipse.org/webtools/repository/kepler
For Helios: http://download.eclipse.org/webtools/repository/helios
For older version: http://download.eclipse.org/webtools/updates/
Downloaded Eclipse Luna and installed WTP using http://download.eclipse.org/webtools/repository/luna
Downloaded Tomcat 8 and configured new server in Eclipse. I am able to setup tomcat 8 now in Eclipse luna
If you have untarred your own version of tomcat v8 with a root user into a custom directory (linux) then the default permissions on the TOMCATROOT/lib directory do not allow normal user access.
Eclipse will not be able to see the catalina.jar to check the version. So no amount of fiddling aorund with the server.properties will help!
just add chmod u+x lib/ to allow normal user access to the libs.
I've been spoiled by .NET development and this is driving me NUTS.
I am on Galileo.
Installed the WTP.
Installed tomcat 6 through the windows installer.
If I go (in eclipse) to Window --> Preferences --> Server --> Runtime Environment I get no tomcat option at all, as in a number of tutorials - only a basic folder with the useless J2EE Runtime Library.
What am doing wrong?
Any help appreciated!
Did you install Eclipse with the J2EE development tools also? There are different version of Eclipse you can download, the standard version only comes with J2SE tools.
You should see a Tomcat folder which allows you to choose the installation folder of the version of tomcat that you choose.
netbeans 6.8
ubuntu 9.10
i am able to build the sample applications, but the doc in the code assistant popup is missing (when type Ctrl + Space)
how to fix this?
For each platform (Version of the JDK, etc) in netbeans, you can specify the location of the JavaDocs
Select the Tools-> Java Platforms menu
Select the Platform you're interested in
In the Javadoc tab, add the zip file or folder with the javadoc files.
The files you want should be in <Netbeans 6.8 install directory>/enterprise6/docs/javaee6-doc-api.zip.
However, if you install the EJB and EAR plugins in the Netbeans Platform these should be setup automatically so perhaps a fresh install is required. (Note: I just added them to my Netbeans install on Karmic and the docs worked.)
