How do I add a new plugin without recompiling in Eclipse RCP? - java

How can I add an unknown plugin to a deployed RCP application without recompiling the application?
I want to:
deploy RCP application.
create a new plugin (language plugin).
drop the plugin into the plugin folder.
???
Finally, the deployed application should use the new plugin.
When modifying the config.ini file and manually adding all the plugins, it works, but I don't want to manually edit the config file. How can I do this automatically?

Spring Loaded , Eclipse and Tomcat integration

Spring loaded can dynamically reload class files in a running web application.
But it can't reload jar files.
Now, I have a project where the Web part includes many other service projects as jar files. All are eclipse based and in the same workspace.
My question is, since we cant reload jars at runtime using spring loaded, can we configure eclipse web project in such a way that
the class files from the service projects are directly copied to my WEB-INF/classes. (I dont want to have jar's of the service projects).
Also do I need to enable the "build automatically" in eclipse to get my changes reflected.
I was able to configure spring-loaded in netbeans with the compile on save option.

How to create war file in eclipse with all the necessary dependencies without maven or ant

I saw lots of questions including this one : How to create an war file in Eclipse without ant or maven?
I have standard web project created with eclipse. In this web project like many others there isn't only jsp and web files, but java files also. I am using eclipse Luna and I am trying to export my project as war but when I use the export option and package it like war it packages only my web content. Normally after I deploy it to tomcat it fails on login in my site because there is no java files on the war. I am new to the web projects and I do not want to use maven or ant. I want to just simply make working war from eclipse and could not find normal way to do that.
Right Click on your Web project --> export --> War file --> Choose destination path and select on Export source files.
See the below screen shot:
After creating Excel2DB22.war. I have imported it again into my IDE. I can see all the files including java also in that project.
See the below SS:
I hope it will help you.

GWT with Maven under Eclipse. What's the development cycle?

I am writing an application that uses GWT, some Spring MVC and Spring Security. Maven is be used to manage the dependencies and Eclipse is my IDE. I've created my application as follows:
webAppCreator -noant -maven -XnoEclipse -out MyApp com.example.MyApp
Then I've imported it into Eclipse as follows:
Imported as Maven project into Eclipse workspace.
In the project settings the "Use Google Web Toolkit" checkbox is ticked.
This project has a WAR directory" is checked. The WAR directory is set to src/main/webapp. The "Launch and deploy from this directory" is unchecked.
Then I test it's all OK:
Click run/debug, choose Web Application (the Google choice), and select target/www as the WAR directory.
So far, so good. Now I want to know how to control the development cycle. For example, I now want to add Spring to my application so I add this block to pom.xml and save it. The Maven Dependencies in Eclipse are expanded to show many new jars (Spring and its dependencies).
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-web</artifactId>
<version>3.0.5.RELEASE</version>
</dependency>
I also edit the web.xml to configure the Spring DispatcherServlet...
Once I've edited pom.xml and web.xml, clicking the debug/run icon on the toolbar will simply run from target/www again without any other steps taking place. This means the old web.xml is used, and target/www/WEB-INF/lib doesn't contain the Spring jars (and Spring's dependent jars). Do I need to drop to the command-line and issue Maven commands whenever particular changes are made?
The ideal answer will describe the development cycle for the above scenario.
My configuration:
GWT: 2.1.
Eclipse: Helios (3.6).
Maven: 2.2.1.
JRE/JDK: JDK 1.6.0.21.
Google Plugin for Eclipse 3.6 version 1.4.0.v201010280102.
Maven Integration for Eclipse (m2eclipse) version 0.10.2.20100623-1649 (this has been configured to point to Maven 2.2.1 environment and NOT to use the embedded Maven3 "instance").
I didn't understand you question completely but I use to create a separated gwt maven project and use apache web server to serve gwt files and then config my main webapp to load gwt files at client/browser. That save me from mixing gwt codes with my main webapp.
Edit regarding your comment:
Forget about gwt for start and read on ...
First you need to make sure that eclipse and maven are playing together correctly so that when you add dependency to you pom eclipse will recognize them too, and your eclipse project setup and structure match with maven.
Second you need to set up a web development configuration so that you can run/test your webapp. You can use maven jetty or tomcat plugin or eclipse tomcat server. IMHO using maven jetty plugin is better.
And Finally you need to package (using maven) and deploy (using maven or not) webapp to your deployment environment.
If you have been successful till now, then you can add gwt in using maven gwt plugin.
If you have installed eclipse maven plugin you can run maven commands from inside eclipse but it wouldn't hurt to run them from command prompt any way.

maven2 war overlay and eclipse WTP

I have a maven war module which run eclipse WTP tomcat server like normal. Now i want to reuse that module artifact by using maven war overlay: i just create a new war project and include that module in project dependencies. The problem is now i cannot use eclipse "Run on server" anymore because i don't have any resource or config file (like web.xml) in the new project, everything is in the war dependencies but eclipse cannot resolve it.
Is there anyway to use a maven war overlay project run with eclipse ?
Thank you.
If you're trying to have a war dependency on a war project, in other words doing a "war overlay", then it's not currently supported by m2eclipse
Jer developped a plugin to implement this feature, you can give it a try : http://code.google.com/p/m2eclipse-wtp-ext/
I've test this(to debug my first JASIG CAS server), and found it works in eclipse:
Using Jetty Maven Plugin to run/debug war overlayed web apps.
Hope helpful~
I am having the same issue here. I agree with you that it's not supported yet (and has not been for almost 2 years!). There seems to be an alternative using q4e version 0.11.0+: http://wiki.eclipse.org/IAM_WTP_support which you can download from https://code.google.com/p/q4e/ or using the update site http://q4e.googlecode.com/svn/trunk/updatesite-iam/ . I'll give it a try and see whether and how it works (with m2eclipse at the same time active).

How to start/stop/redeploy maven web app using cargo start inside Eclipse

I have Maven2 war project built, I'm using the cargo start plugin, and it works great for deploying the web app. To run the maven command, I use a .bat file in my workspace, and I have en external run config to run the the bat file. I can't seem to stop the server from the Eclipse console, or re-deploy.
Does anyone have any advice on how quickly start/stop/re-deploy to Tomcat locally while developing.
Did you try JavaEE tools and m2eclipse? As far as I can see it should work well in most common situations. What m2eclipse does for you is to exactly map the maven configuration to an eclipse projects with the necessary facets set. Also, if the Dynamic Web Application facet is set for your project, you will be able to deploy it to a Tomcat server that you set up in the Server view of JavaEE tools. This configuration allows hot redeploy.
More information on JavaEE tools:
http://eclipse.org/home/categories/index.php?category=enterprise
There is a full Eclipse distribution with the EE tools available on their download site:
http://www.eclipse.org/downloads/
m2eclipse is freely available from Sonatype:
http://m2eclipse.sonatype.org/
At work we use the mentioned software as well. Additionally we use the JBoss tools that provide a feature called Project Archives that let you individually build your web application archive (ear/war/...).
To get startet you should perhaps start a fresh workspace and import the existing maven project (via the import existing maven project wizard). If everything went fine you can set up your tomcat in the server view. Maybe switch to the Java EE perspective. Right click on the newly added server and select Add to add the dynamic web project you just imported. If it doesn't show up in the list try to update the project configuration via the project's maven context menu.
Well, you could use cargo:redeploy to Undeploy and deploy again a deployable (that's a shortcut to cargo:deployer-redeploy). But I personally don't use Cargo this way, I use it mostly for integration testing (i.e. during the build) and use Eclipse WTP during development (this works whether you're using the maven eclipse plugin or m2eclipse).
