GWT can debug the complete instance of the customer and service in the eclipse and Tomcat (database connection pool) Step by Step-expand tomcat in the Host Mode

Use Tomcat for browsing, instead of the built-in GWT, so that Tomcat context information can be obtained and the client can be submitted in one step.

Complete source code (for the convenience of the compiled files): wylpeace-Tomcat

Environment Establishment
1, download eclipse3.2: http://download.eclipse.org/eclipse/downloads/index.php
2, download tomcat5.5: http://tomcat.apache.org/download-55.cgi
3, download Tomcat Plugin: http://www.sysdeo.com/eclipse/tomcatplugin
4, download googlipse plug-in: http://sourceforge.net/projects/googlipse
5. Install the SDK (go to Google for installation)

Officially started
Create a GWT project developed with eclipse (use the eclipse and googlipse plug-ins. If you do not want to build it, you can download the source code)
There are two methods: a gwt Command Line Method B googlipse plug-in
The B method is used here.
1. download and install the googlipse plug-in
2. Configure the googlipse plug-in.
Window -- preferances -- googlipse: enter the correct location of the GWT development kit.
3. Create a "googlipse -- GWT project" project named wylpeace
In the following steps of the wizard, modify

Note the modifications made in "Default Output Folder" below the Graph

4. Create the directory structure "wylpeace/samples/select" under "src"
5. Right-click the select package and choose "New"> "GWT module"
Add your own content (refer to the source code)

Configuration of Tomcat database connection pool

Reference: http://www.blogjava.net/peacess/archive/2006/06/29/55778.html
The simplest method is to copy the two files "server. xml" and "context. xml" under the source code directly to tomcat5.5/CONF.

Configure the Tomcat runtime environment in eclipse

Configure the plug-in first
Window -- "preference --" Tomcat: Configure "Tomcat home" and "Tomcat vesion" -- "advanced: Configure" Tomcat base "(the same as" Tomcat home ") --" JVM setting: select "JRE". Note that it must be the JRE under JDK. Otherwise, the server code cannot be debugged.

Then (there are a lot of configuration content, there is no way)
1, add the file "Web. xml" content under "WEB-INF" such as source code
2. Create a directory "lib" under "WEB-INF"
3, process the gwt-user.jar file (cannot directly put into the lib directory), here ant to operate, create an ant file "build. XML, note to modify the gwt-user.jar path, open it, right-click on the right and choose stripgwt-lib -- run. In this way, a gwt-user.jar file that can be used under Tomcat is generated under the "lib" directory.

Configure hosted of GWT

1, extract the gwt-user.jar (under the original GWT)
2. Copy the "GWT-user/COM/Google/GWT/CORE/public/gwt-hosted.html#history.html" file to "www/wylpeace. samples. select. wylpeaceselect (this is a key step for One-Step client debugging)
3. Right-click the project "wylpeace" -- "Debug as --" debug ", as shown in

Note the selected part "-noserver-port 8080" in the figure (in this way, the default port 8888 of GWT can be changed ),
Modify the "classpath" label in this figure as follows:
Select "User entries" -- "Advanced --" OK -- "and select" wylpeace/Web-INF/classes "--" OK.

All configurations are complete. We can start single-step debugging.
Restart Tomcat (in eclipse) and run "wylpeace. samples. Select. wylpeaceselect" in debugging"
The webpage cannot be found. The URL is changed to http: // localhost: 8080/www/wylpeace. samples. Select. wylpeaceselect/wylpeaceselect.html.
