View source for Setup MySQL DB in Eclipse

__TOC__

= Foreword =
ZK framework's architecture allows you to use any database. Here we just give you some hints on how you can connect to MySQL in Eclipse, and such configuration is independent of ZK framework. 

To see a simple ZK-based example with a database, please check [http://books.zkoss.org/zkessentials-book/master/jpa_integration/index.html ZK Essentials]

= Prerequisite =

'''1.''' The  [http://www.eclipse.org/datatools/ Data Tools Platform (DTP)] is required for setup DB connection, the '''''Eclipse IDE for Java EE Developers''''' distribution of Eclipse we mentioned in [[ZK Studio Essentials]] has already include DTP, so in most case it is not necessary to do extra Eclipse DTP plug-in installation.

'''2.''' Download MySQL Connector/J:<br/>
:http://dev.mysql.com/downloads/connector/j/ (choose "Platform independent") and download the zip version
extract the zip file to a proper location.

'''Note.''' Different versions of Eclipse may have different settings. Please reference Eclipse official documents if the samples/links listed in this page are not matching what you are using.

= Setup Database Connection in MySQL =
# Open Data Source Explorer via '''<nowiki>[Window]/[Show View]/[Other...]/[Data Management/[Data Source Explorer]</nowiki>''':<br/>[[Image:001_open_DataSourceExplorer.png]]<br/><br/>
# Right click the Database Connection folder, select '''<nowiki>[New...]</nowiki>'''.<br/>[[Image:001-1_New_Database_in_DataSourceExplorer.png]]<br/><br/>
# Select the Database you suppose to connect ( ''MySQL 5.1'' as the example in this document), you can type custom name and description for mnemonic, click <span style="border-style: outset;font-weight: bold">&nbsp;Next&nbsp;&gt;&nbsp;</span>.<br/>[[Image:002_select_DB_Type.png]]<br/><br/>
# On next page, click the '''''New Driver Definition''''' icon next to the '''<nowiki>Drivers:</nowiki>''' listbox.<br/>[[Image:003_new_DriverDef.png]]<br/><br/>
# On the popup window, select the Database Version in ''Name/Type'' tab.<br/>[[Image:004_chose_MySQL_DBVer.png]]<br/><br/>
Swith to ''Jar List'' tab, click <span style="border-style: outset;font-weight: bold">&nbsp;Clear All&nbsp;</span> to clear the default false jar file location.<br/>[[Image:005_clear_redundant_Jar.png]]<br/><br/> then click <span style="border-style: outset;font-weight: bold">&nbsp;Add JAR/Zp...&nbsp;</span>.<br/>[[Image:006_specify_MySQL_connector_Jar.png]]<br/><br/>Locate the jar file inside the folder that just extracted from downloaded MySQL Connector/J zip file.<br/>[[Image:007_locate_MySQL_connector_Jar_file.png]]<br/><br/>Switch to '"Properties" tab, modify the database connection setting according to your MySQL Database configuration, then click <span style="border-style: outset;font-weight: bold">&nbsp;OK&nbsp;</span></br></br>'''Note:'' The JDBC URL format for MySQL Connector/J is as follows, with items in square brackets ([, ]) being optional:

<pre>jdbc:mysql://[host:port],[host:port].../[database][?propertyName1][=propertyValue1][&propertyName2][=propertyValue2]...</pre>

If the hostname is not specified, it defaults to 127.0.0.1. If the port is not specified, it defaults to 3306, the default port number for MySQL servers. In above image the database name is '''<tt>test</tt>'''

<pre>jdbc:mysql://localhost:3306/test</pre><br/>[[Image:008_specify_MySQL_connection_setting.png]]<br/><br/>
# To verify if the setup is functional, click <span style="border-style: outset;font-weight: bold">&nbsp;Test Connection&nbsp;</span>.<br/>[[Image:009_test_MySQL_connection.png]]<br/><br/>It should popup a Ping succeeded message, Click  <span style="border-style: outset;font-weight: bold">&nbsp;OK&nbsp;</span> to continue.<br/>[[Image:010_test_MySQL_connection_succeed.png]]<br/><br/>
Note: Make sure the MySQL database is up and running. If it is not running, the Test Connection will fail. If you don't know how to find if MySQL is running then please [https://www.google.com/search?q=how+to+check+if+MySQL+is+running google search] it <br/><br/>
# Press <span style="border-style: outset;font-weight: bold">&nbsp;Finish&nbsp;</span> to close the setup wizard window, And you should be able to see there's a Database icon in the Database Connections folder.<br/>[[Image:011_MySQL_DB_shown_in_DataSourceExplorer.png]]<br/><br/>

= Note =
#Firewall of the System that install Database or security setting of the Database may prevent you from connect the DB successfully.
#If you had specify the right '''MySQL Connector/J''' jar file before, then Step '''4''' &amp; '''5''' can be skipped, you can directly modify the following field to match your MySQL Database configuration<nowiki>:</nowiki><br/>[[Image:012_modify_MySQL_DB_connection_setting.png]]<br/>then proceed the subsequent steps to finish setup.<br/>
