ofbiz实体引擎结合jbuilder的配置

最近在研究ofbiz，希望和有兴趣的人一起交流。
我的email:yangzhihong@sina.com

1.1 配置
这一节将给出实体引擎在jbuider中单独使用的配置向导
本文是从ofbiz网站的（OFBiz Quick Start Guide by Brett G. Palmer）的基础上完成配置。

1．从www.ofbiz.org中下载ofbiz-XX-XX-complete.zip包，本文用的是ofbiz-2.1.1-apps.zip
解开放到某个目录下，本文在j:\ofbiz,这也就是ofbiz.home的值
2．建立jbuilder项目，如下图所示

3．加入源文件，
ofbiz.home/core/src/entiry
ofbiz.home/core/src/share

4．加入所用到的jar文件
ofbiz.home/lib/common
ofbiz.home/lib/compile
ofbiz.home/lib/jasterreports
ofbiz.home/lib/jotm
ofbiz.home/lib/scripting
ofbiz.home/lib/share
ofbiz.home/lib/tyrex

5．将配置文件等导入工程
将ofbiz.home/commonapp/etc下所有文件打到ofbiz_etc.jar包内
jar cvf ofbiz_etc.jar *
将ofbiz.home/core/docs/xmldefs/ofbiz下所有文件打到ofbiz_dtd.jar包内
jar cvf ofbiz_dtd.jar *

将这两个包引入工程。

6．将ofbiz.home\setup\jrun4\servers\ofbiz\SERVER-INF\jndi.properties文件放入
ofbiz.home\lib\jotm\jotm.jar包内

7．配置ofbiz.home
在项目run tab中加入vm parameter:
-Dofbiz.home=j:\ofbiz

8．在GenericDelegator.java中，将下面语句注释掉。
/*
// setup the Entity ECA Handler
try {
Class eecahClass = loader.loadClass(ECA_HANDLER_CLASS_NAME);
this.entityEcaHandler = (EntityEcaHandler) eecahClass.newInstance();
this.entityEcaHandler.setDelegator(this);
} catch (ClassNotFoundException e) {
Debug.logWarning(e, "EntityEcaHandler class with name " + ECA_HANDLER_CLASS_NAME + " was not found, Entity ECA Rules will be disabled");
} catch (InstantiationException e) {
Debug.logWarning(e, "EntityEcaHandler class with name " + ECA_HANDLER_CLASS_NAME + " could not be instantiated, Entity ECA Rules will be disabled");
} catch (IllegalAccessException e) {
Debug.logWarning(e, "EntityEcaHandler class with name " + ECA_HANDLER_CLASS_NAME + " could not be accessed (illegal), Entity ECA Rules will be disabled");
} catch (ClassCastException e) {
Debug.logWarning(e, "EntityEcaHandler class with name " + ECA_HANDLER_CLASS_NAME + " does not implement the EntityEcaHandler interface, Entity ECA Rules will be disabled");
}
*/


9．测试文件Test.java
package org.ofbiz.core;

import org.ofbiz.core.entity.GenericDelegator;
import org.ofbiz.core.entity.GenericValue;
import org.ofbiz.core.util.UtilMisc;
import org.ofbiz.core.entity.*;


public class Test {
public static void main(String[] args) {
System.out.println("Entered testFindByPrimaryKey");
//Instantiate the delegator.
GenericDelegator delegator = GenericDelegator.getGenericDelegator("default");


// Find book by primary key
try {
GenericValue party= delegator.findByPrimaryKey("PartyType",
UtilMisc.toMap("partyTypeId", "PERSON"));
}
catch (GenericEntityException ex1) {
}
return;
}

}

10.ok

好文，顶

谢谢，希望能给大家更多的帮助！

你把你配置好的东西压缩，上传上来吧。可以直接运行的

前段时间我研究过一阵子ofbize entity engine，发现他有几个问题，一个是对数据查询的分页不支持，只提供了一次查询返回所有记录的接口，效率很低。二是对于熟练的开发人员来说，它的查询接口显得很难用，不如sql。三是它的数据库配置文件不支持字段默认值（时间长了记不太清楚，记得当时好像翻遍了它的文档，也作了测试，好像是不支持默认值，而且对索引似乎也不支持）。四是它的entity和具体的java object没有映射关系。

因此我最后放弃了entity engine，转向castor jdo。jdo具有entity engine具有的功能，但是比它更自然更好用。


entity engine也有一些值得我们学习的地方，一是自动创建和维护数据库结构，二是通过使用中间类型做到数据库独立。

有20M，在jdon能传吗？

各位大虾，我想单独使用ofbiz 的entity engine(ofbiz preview 3.0),请各位诊断一下：
1）ant build file(independbuild.xml ):
<?xml version="1.0"?>


<project name="OFBiz - Entity" default="jar" basedir=".">

<!-- ================================================================== -->

<property name="lib.dir" value="lib"/>
<property name="build.dir" value="build"/>
</target>

<target name="classpath">

<pathelement location="."/>

<pathelement location="entitydef"/>

</path>
</target>


<!-- ========================================================================

<target name="run"

depends="init,classpath">
<java classname="org.ofbiz.entity.Test" fork="true">
<classpath refid="local.class.path"/>
</java>
</target>

</project>

2) Test.java File:

package org.ofbiz.entity;

import org.ofbiz.entity.GenericDelegator;
import org.ofbiz.entity.GenericValue;
import org.ofbiz.base.util.UtilMisc;
import org.ofbiz.entity.*;


public class Test {
public static void main(String[] args) {
System.out.println("Entered testFindByPrimaryKey");
//Instantiate the delegator.
GenericDelegator delegator = GenericDelegator.getGenericDelegator("default");


// Find book by primary key
try {
GenericValue party= delegator.findByPrimaryKey("SequenceValueItem",
UtilMisc.toMap("seqName", "Party"));
System.out.println("seqName=["+party.getString("seqName")+"] seqId=["+party.getString("seqId")+"]");
}catch (GenericEntityException ex1) {
}
return;
}

}

3)重新build entity engine
4)run -f independbuild.xml run 后出现如下信息：

D:\ofbiz\components\entity>ant -f independentbuild.xml run
Buildfile: independentbuild.xml

init:

5）问题：如何才能找到SequenceValueItem的definition,不想让JobManager等出来？
