Eclipse ResourceBundle Editor

It is good for editing resource bundles. Let you manage all localized properties files in one screen. Easy to handle Unicode. I agree it should be a standard plugin of eclipse. :)

Alternative way to do remote debug in eclipse

The normal way to do the remote debug is to add the JVM argument which opens a port on the machine where the java code is running and the client eclipse is going to hook up that port on that machine.

-Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=1044

But in some cases, the server does not allow you open and connect on a new port because of the security issue, blar blar balr... There is an alternative way to do the remote debug which is open a port on the machine where eclipse is running, and let the server connect to that machine.

The JVM argument on server is

-Xdebug -Xrunjdwp:transport=dt_socket,address=142.174.39.161:6767

This tells the JVM that all debug information should be sent to 142.174.39.161:6767. The ip address is the ip of the machine where eclipse is running. In eclipse, you only need setup it listen on port 6767.

Skip Over Dynamic Proxy Classes when Debugging in Eclipse

Setup the step filter for java debug to skip the proxy class.

$Proxy* will ignore the proxy class.

M2clipse and Eclipse 3.5 WTP

I want maven to manage the dependency and WTP to enable the tomcat inside eclipse. M2clipse and WTP are separated projects and they are not friendly to each other.

Before start, make sure M2clipse already installed. 

New Dynamic Web Project in eclipse.

In the wizard, change the src path, output folder and the webContent dir to be the one used by maven.

src
src/main/java
src/main/resource

output folder
target/classes

webContent
src/main/webapp

 

When the project is created, you can setup a tomcat server. The project created is able to be added to the tomcat server.

Maven –> Enable Dependency Management

Right click the project, Maven –> Enable Dependency Management

It will popup the window to let you input groupid, artifactid…..

Once it is done, it will generate the pom.xml and related files for m2clipse. The project is still able to be added to the tomcat server.

You may have the error “Java compiler level does not match the version of the installed Java project facet.” Change the compiler version in org.eclipse.jdt.core.prefs in the .settings. dir.

Right click the web project –> Properties –> Java EE Module Dependencies

select Maven Dependencies and the project in the same workspace. In the example below, my web project depends on the quartzspring project in the workspace.

Publish the tomcat, look into the directory where it is deployed, check if all files are there. It works for me.

Eclipse dropins dir

可以直接将 plugin 放到 dropins 目录下，即可自动完成安装。
dropins 目录支持下列形式的结构。
1、

eclipse/
--dropins/
  --org.eclipse.core.tools_1.4.0.200710121455.jar
  --org.eclipse.releng.tools_3.3.0.v20070412/
    --plugin.xml

2、

eclipse/
--dropins/
  --eclipse/
    --features/
    --plugins/

3、

eclipse/
--dropins/
  --emf/
    --eclipse/
      --features/
      --plugins/
   --gef/
     --eclipse/
       --features/
       --plugins/
... etc ...

4、

eclipse/
--dropins/
  --emf.link
最后一种就相当原来的 links 目录，只要写
path = ...  就可以了。
