IDEA allow to find bean definition, declared in xml, right from Java code. For example if I've got interface SomeIntrfaceImpl IDEA allow me to find out instances of SomeIntrfaceImpl in .xml contextes files, pointing me to .xml file to line of code where bean is created
Is there any Eclipse plugin, that allow me to do the same ?
Yes there is different Eclipse provided by SpringFramework makers itself. They have extended the eclipse to provide easy development for Spring web application and other products like Spring ROO also.
Its is called SpringSourceToolSuit. You can download its latest version from here after providing some basic information about you asked in a form there.
Its the best IDE to develop Spring applications. I am currently using it.
Hope this helps you. Cheers.

I follow some guide, In the video, Their IDE have all those functions (by default! no config needed):
No auto compile in any type
No Spring entry in "NEW" or "XML Configure File" in XML or anything handy
No Spring XML editor in "OpenWith"
etc....
Almost everything is missing
I try both way: Download STS4 or install STS in Eclipse
None of them working
So: How to get those lost function ?
The tutorial you are following is probably using STS3, which contains all the features for Spring XML config files that you mentioned. However, the tooling that you have installed is Spring Tools 4 for Eclipse, which comes with a different set of features. It supports Spring XML config files, too, but in a different way. It is much more focused on implementing apps on top of Spring Boot. You can find more details in the Spring Tools 4 wiki: https://github.com/spring-projects/sts4/wiki
I am learning AOP with Spring framework and I want to set the javadoc for AOP in eclipse. So what I did I downloaded aspectj-1.8.10.jar from eclipse web site https://eclipse.org/aspectj/downloads.php#install then I installed that jar and got 4 new jar files: aspectjrt.jar, aspectjtools.jar, aspectjweaver.jar, org.aspectj.matcher.jar which I added to my class path in eclipse. Now what I want is to add source files for these jars so, for example, when I hover over #Aspect I want to be able to see what this annotation represents. Unfortunately I can not find the source files for these jars, on the eclipse website mentioned above there is a file aspectj-1.8.10-src.jar but I'm not sure what to do with it, I tried to attach this file directly in the build path for each of the jars mentioned above but it didn't do the trick. Also I thought that maybe I had to install aspectj-1.8.10-src.jar the way I installed aspectj-1.8.10.jar so I would get 4 source files, but I'm not sure how (if possible) to install it, when I double click aspectj-1.8.10-src.jar, installation does not get triggered.
So can you please help me out to add javadoc for AspectJ 1.8.10 in Eclipse?
Select the library in your Eclipse project explorer window, click right button, select properties, select javasource attachment or javadoc location and enter the path to the source or javadoc file.
But I would suggest to use maven to maintain the dependencies of your project. It makes getting javadoc much easier, because libraries, source code and javadoc are fetch from a central repository. You just add the library you need in your project configuration (pom.xml file) and the other files are fetched for you.
You do not need all those libraries. Please first learn which one serves which purpose. E.g. aspectjrt is the runtime. When using Spring AOP you actually do not really use AspectJ, only a subset of its syntax. Thus, the runtime is needed for identifying some of the annotation classes. However, aspectjweaver is only needed if you want to use full AspectJ in a load-time weaving (LTW) scenario, with or without Spring. The weaver lib is a superset of the runtime, so you only need one of them. Last, but not least, aspectjtools again is a superset of the weaver lib and contains the AspectJ compiler (among other tools). This is only needed for compile-time weaving as part of your toolchain.
I do not think that source code and Javadoc will help you much in learning AspectJ. I suggest you read the Spring manual's AOP chapter describing both proxy-based Spring AOP and full AspectJ integration via LTW. If you want to learn AspectJ basics and maybe just use AspectJ without Spring (which is what I do), read the AspectJ documentation.
If you are still not convinced and want to add source and JavaDoc to your Eclipse project, why don't you follow jaysee's advice and use Maven? Then you get all the source/javadoc libs for free. But anyway, you can also load those JARs directly from Maven Central, e.g. the source and javadoc for AspectJ runtime 1.8.10. Good luck! But I assume you will be disappointed because the AspectJ JavaDoc is really bad for learning purposes and not suited to understanding how to actually use AspectJ.
I have started creating the Spring web application where I need to mention the spring classes in the XML configuration files, for ex, the deployment descriptor (web.xml) where I need to mention the DispatcherServlet class of Spring.
What I am looking for is, I want eclipse to show me the list of packages/classes when I type org.springframework..., like we do in the Java editor. I have googled to find out, but no luck. I am sure there would be plugins available. Can any of you please share me on how to fix this?
Since you are working on a spring project, I'd recommend installing the SpringToolSuite (STS). The info page is here: http://spring.io/tools
Since you already have an Eclipse instance that you are working with, you should go with the update sites: http://dist.springsource.com/release/TOOLS/update/e4.4/
(Make sure to use the correct update site for the Eclipse version you are using.)
Not only does STS include all tools for XML editing, but it also includes special tools for editing your Spring application files.
How I can setup Hibernate for a Dynamic Web application by using Eclipse Helios? I am a newbe so please let me know if there is any example.
I tried for Java application and included all JARS and it worked fine. But don't understand how I can do it for Web application and test it.
I will use Struts2 so I will appreciate if I can get appropriate example or guidance.
Drop the jars in WEB-INF/lib. Those jars are automatically added by Eclipse to the project build path, and constitute (with the WEB-INF/classes directory and the container classpath) the classpath of the webapp.
http://hardik4u.wordpress.com/2008/09/02/struts-2-hibernate-3-integrationcomplete-using-eclipse/
https://stackoverflow.com/questions/4364923/struts2-and-hibernate-framework-create-in-eclipse
First, download Struts2, and import example WAR file into Eclipse. You can find it from the source folder: struts-2.3.1-all\struts-2.3.1\apps\struts2-blank.war
Second, you should install Eclipse Hibernate Plugin. Goto Window > Preferences > Install/Update > Available Software Sites and add following link and name it JBossTools or something.
http://download.jboss.org/jbosstools/updates/helios/
Depending on your needs you can install Hibernate Plugins for many project types. In this case, select web application plugin.
And after, you should include Hibernate Core libraries into your classpath. I would recomment Hibernate 3.6 and greater. Because it does not depend on asm (asm-3.3.jar, asm-commons-3.3.jar ...) anymore. If you use earlier versions you might encounter some problems, since Struts2 also depend on asm libraries.
Then create your database, and use following link to configure and generate model bean classes.

Now you don't need to write mapping files by yourselves. And with DAO factory pattern you have your way to finish your project.
Hope this helps, and Goodluck
Is it possible to use a Spring container for DI from inside Eclipse plugins?
I'm wondering because I know that Eclipse causes a lot of issues with class loading, looking up things within the plugin, etc.
The plugin is intended to be distributed as a JAR.
Yes but you will need Spring DM http://www.springsource.org/osgi
The answer is yes. You can use Spring DM, but you don't have to. It is probably better with it.
I did it without Spring DM and the main concern is class loading issues (not sure if Spring DM solves them, but I guess it should). Assuming you bundle the Spring JAR in a separate plugin with dependencies, you will need to load the context with the class loader of the invoking plugin .
Example:
Plugin A - your functional plugin
Plugin B - The Spring lib plugin exporting the spring packages
Plugin A depends on B. When plugin A starts, it will load the application context, when invoking this load, you will need to do something like:
Thread.currentThread().setContextClassLoader(PluginAActivator.class.getClassLoader())
So that the loading of the classes will happen under your own class loader. Now you can use a ClassPathXmlApplicationContext to load configuration XMLs from your class path.
One small note: the default ClassPathXmlApplicationContext validates your XMLs upon loading. You may want to disable it or point your XMLs to a local schema (rather than the standard Spring schema on springframework.org), otherwise, you will connect to the internet to download the schema files upon loading and working offline will fail.
do you have a code example for your post?
This would be great, since I´m hanging around with this for a while.
Cheers!
