EJB 从WL6.1向WL8.1移植（MAPS EJB Migrate from WLS6.1 to WLS8.1 Guideline）

1. Fix Syntax Error 

1) Use WLS8.1 Tools “Weblogic Builder” Re-Gen the EJB description files (weblogic-ejb-jar.xml, ejb-jar.xml, weblogic-cmp-rdbms-jar.xml)   由于在EJB的描述文件中的头部指明了server的版本，所以在使用的时候6.0的版本文件不能被8.1的版本识别。可以在本地（win环境）中安装wl8.1后使用Start Menu/Programs/BEA WebLogic Platform 8.1/Other Development Tools/WebLogic Builder实现。只需要指向打你的ejb的source文件就可以实现那！执行后会在产生一个build的文件夹里面的描述文件转换为8.1 的了！ 

2) Fixed All EJB description files EJB-QL syntax error (weblogic-ejb-jar.xml, ejb-jar.xml, weblogic-cmp-rdbms-jar.xml)For example: Example 1)

File:ejb-jar.xml        <ejb-ql>             FROM ManufacturerEJB AS m</ejb-ql>Should be changed to:<ejb-ql><![CDATA[SELECT OBJECT(m) FROM ManufacturerEJB AS m]]></ejb-ql> 

Example 2)

File: weblogic-cmp-rdbms-jar.xml

 <weblogic-ql>       FROM ManufacturerEJB AS m ORDERBY m.shortname</weblogic-ql>Should be changed to:<weblogic-ql><![CDATA[SELECT OBJECT(m) FROM ManufacturerEJB AS m ORDERBY m.shortname]]></weblogic-ql> 

Example 3)

File: weblogic-cmp-rdbms-jar.xml

<weblogic-ql>

<![CDATA[SELECT OBJECT(a) FROM ManufacturerEJB AS a WHERE a.shortname = ?1 ORDERBY shortname]]>

</weblogic-ql>

Should be changed to:<weblogic-ql><![CDATA[SELECT OBJECT(a) FROM ManufacturerEJB AS a WHERE a.shortname = ?1 ORDERBY a.shortname]]>

</weblogic-ql>

 8.1的中对描述文件中的格式要求严格，所以注意有关在其中的修改！ 

2. Package all EJB into one EJB named “WizdomEJB.jar” (Fix the local interface problem)

2.1 Combine ejb-jar.xml into one.       a)Retrieve the statements between   <enterprise-beans>  and   </enterprise-beans> from ejb-jar.xml in every EJB jars, and insert into the place between <enterprise-beans>  and   </enterprise-beans> in ejb-jar.xml of the WizdomEJB.jar.       b) Retrieve the statements between  <assembly-descriptor> and  </assembly-descriptor> from ejb-jar.xml in every EJB jars, and insert into the place between <assembly-descriptor> and  </assembly-descriptor> in ejb-jar.xml of the WizdomEJB.jar.2.2 Combine weblogic-cmp-rdbms-jar.xml into one.       Retrieve the statements between  <weblogic-rdbms-jar> and  </weblogic-rdbms-jar> from weblogic-cmp-rdbms-jar.xml in every EJB jars, and insert into the place between <weblogic-rdbms-jar> and  </weblogic-rdbms-jar>  in weblogic-cmp-rdbms-jar.xml of the WizdomEJB.jar.2.3 Combine weblogic-ejb-jar.xml into one. Retrieve the statements between  <weblogic-ejb-jar> and  </weblogic-ejb-jar> from weblogic-ejb-jar.xml in every EJB jars, and insert into the place between <weblogic-ejb-jar> and  </weblogic-ejb-jar>  in weblogic-ejb-jar.xml of the WizdomEJB.jar.2.4 Combine class files into one.       Copy the class files in every EJB jars into the class path of the WizdomEJB.jar. 

3. Re-Compile EJB use WLS8.1 library and EJBC

a) Change property file:/apps/maps/src/old/components/com/wisdom/maps.propertiesChange Weblogic Home to WLS 8.1 Home: For example: WL_HOME=/bea/weblogic812) Change build.xml file to meet the new environmentFor example: <classpath><pathelement path="${WL_HOME}/lib/weblogic.jar” /></classpath>Should be changed to:<classpath><pathelement path="${WL_HOME}/server/lib/weblogic.jar” /></classpath>两个例子build.xml文件：一：     <project name="ejb20-basic-containerManaged" default="all" basedir=".">  <!-- set global properties for this build -->
