liferay 上集成JBPM Workflow工作流配置

网上很多流传着这样一种配置方式，我照着这样配置完成还是不能使用，这只是配置的一部分，因为我用了JBPM工作流..相应还需要修改修改里面的Java文件...调整了很长时间才搞通..

1．Liferay官方网站下载liferay-portal-jbpm-web-5.2.3.war，liferay-portal-servicemix-web-5.3.3.war或者liferay-portal-muel-web-4.3.2.war.(我用的是4.3.2,你下自已用的版本,不能错)
2．三个包都放到/webapps下面,liferay启动后会自动的解压，或者用WINRAR也可以解压。
3．webapps\ROOT\WEB-INF\classes\portal-ext.properties增加jbi.workflow.url=http://localhost:8080/servicemix-web/workflow或jbi.workflow.url=http://localhost:8080/mule-web/workflow注意端口号要和自已的相同。
4．如果要修改端口号那么还要修改webapps\mule-web\WEB-INF\mule-config.xml下<property name="url" value="http://localhost:8082/jbpm-web/servlet" />端口号；webapps\servicemix-web\WEB-INF\applicationContext.xml下<property name="url" value="http://localhost:8082/jbpm-web/servlet" />端口号。
5．webapps\jbpm-web\WEB-INF\classes\hibernate.cfg.xml,先择自已用到的数据库类型并配置， webapps\jbpm-web\WEB-INF\sql下面有各种数据库脚本，选择自已的导入库中。


第二部分：修改的文件；
After you have deployed following components (version 5.2.0.1) under liferay 5.2.3,
- workflow-portlet
- mule-web
- jbpm-web

please replace two classes
- mule-web
   WEB-INF\classes\com\liferay\jbi\mule\util\URLTransformComponent.class
- workflow-portlet
   WEB-INF\classes\com\liferay\workflow\service\impl\WorkflowDefinitionServiceImpl.class

and the workflow with jbpm should be ok.
-------

Please find the source code files in the attachement, corresponding to the classes in last mail.

- workflow-portlet
    src\com\liferay\workflow\service\impl\WorkflowDefinitionServiceImpl.java
 
- mule-web
   src\com\liferay\jbi\mule\util\URLTransformComponent.java

对应的Java类对应如下：

package com.liferay.jbi.mule.util;

import com.liferay.portal.kernel.util.Http;
import com.liferay.portal.kernel.util.HttpUtil;

import java.io.IOException;
import java.util.Map;

import javax.servlet.http.Cookie;

import org.mule.components.simple.LogComponent;
import org.mule.umo.UMOEventContext;

/**
* <a href="URLTransformComponent.java.html"><b><i>View Source</i></b></a>
*
* @author Charles May
*
*/
public class URLTransformComponent
extends LogComponent implements URLTransformService {

public String getUrlResult(Map parameters, String url) {
String xml = "<result />";

try {
//
// Method signature changed(add one Http.Auth) in new version.
// public static String URLtoString(
// String location, Cookie[] cookies, Http.Auth auth,
// Map<String, String> parts, boolean post)
    //throws IOException {...}
//
//xml = HttpUtil.URLtoString(url, null, parameters, true);
xml = HttpUtil.URLtoString(url, null, null, parameters, true);
}
catch (Exception e) {
}

return xml;
}

public Object onCall(UMOEventContext context)
throws Exception {

super.onCall(context);

Map parameters = (Map)context.getTransformedMessage();

String url = (String)context.getMessage().getProperty("url");

return getUrlResult(parameters, url);
}

}

catch (NoSuchFileException nsfe) {

}

这样修改后，应该就可以使用了..只需要自己写JBPM definition.xml 文件..工作流系统就可以使用了。
