我正在尝试使用JCA和CICSECI功能通过CICS事务网关连接到IBM Mainframe。

我的Servlet代码是：

package com.ebs.jca.web;

import java.io.IOException;

import javax.annotation.Resource;
import javax.resource.ResourceException;
import javax.resource.cci.Connection;
import javax.resource.cci.ConnectionFactory;
import javax.resource.cci.Interaction;
import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import com.ebs.cics.copybook.T060.T060REQUEST;
import com.ebs.cics.copybook.T060.T060RESPONSE;
import com.ibm.connector2.cics.ECIInteractionSpec;

/**
 * Servlet implementation class CICSServlet1
 */
@WebServlet("/CICSServlet1")
public class CICSServlet1 extends HttpServlet {
    private static final long serialVersionUID = 1L;

    @Resource(lookup="eis/cicsECI_CF")
    private ConnectionFactory cf = null;


    /**
     * @see HttpServlet#HttpServlet()
     */
    public CICSServlet1() {
        super();
        // TODO Auto-generated constructor stub
    }

    /**
     * @see HttpServlet#doGet(HttpServletRequest request, HttpServletResponse response)
     */
    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        T060REQUEST t060Req = new T060REQUEST();
        t060Req.setAccountNumber("10917683");
        t060Req.setApplication("ST");
        t060Req.setTransactionId("T060");


        T060RESPONSE t060Resp = new T060RESPONSE();
        try {
            Connection eciConn = cf.getConnection();
            Interaction eciInt = eciConn.createInteraction();


            // Setup the interactionSpec.
            ECIInteractionSpec eSpec = new ECIInteractionSpec();
            eSpec.setCommareaLength(8000);
            //eSpec.setReplyLength(20);
            eSpec.setFunctionName("EBOT060");
            eSpec.setInteractionVerb(ECIInteractionSpec.SYNC_SEND_RECEIVE);

            eciInt.execute(eSpec, t060Req, t060Resp);
            //eciInt.execute(eSpec, t060Req, t060Resp);
            /*System.out.println("return code is:");
            System.out.println(t060Resp.getReturnCode());

            icbResp.setResp__code(Short.toString(t060Resp.getReturnCode()));
            icbResp.setResp__text(t060Resp.getReturnText());*/
        } catch (ResourceException e) {
            e.printStackTrace();
            //throw e;
        } catch (Exception e) {
            e.printStackTrace();
            throw e;
        }


        response.getWriter().append("Resp: ").append(Short.toString(t060Resp.getReturnCode())).append(", text: ").append(t060Resp.getReturnText());
    }

    /**
     * @see HttpServlet#doPost(HttpServletRequest request, HttpServletResponse response)
     */
    protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        // TODO Auto-generated method stub
        doGet(request, response);
    }

}

我得到的证明是：

[err] com.ibm.connector2.cics.CICSUserInputException: CTG9628E InteractionSpec passed to execute() not of type ECIInteractionSpec

当我搜索错误代码时。 IBM文档指出： https://www.ibm.com/support/knowledgecenter/en/SSZHFX_9.2.0/CTG9628E.html

“查看Java客户端应用程序。有关更多详细信息，请参阅产品文档。”

我已经阅读了以下教程，但是它们没有显示完整的构建环境。 https://developer.ibm.com/cics/2014/05/06/using-jca-with-the-cics-tg-in-websphere-liberty-profile/ https://github.com/cicsdev/cicstg-jca-liberty-sample

使用示例代码时，我也会遇到相同的错误。

我还尝试按照此链接中的说明设置connectionFactory：

https://www.ibm.com/support/knowledgecenter/SSGMCP_5.3.0/com.ibm.cics.ts.java.doc/topics/dfhpj2_jca_remote_eci_devconfig.html

当我如图所示设置connectionFactory时：

<connectionFactory id="com.ibm.cics.wlp.jca.local.eci" jndiName="eis/ECI">
    <properties.com.ibm.cics.wlp.jca.remote.eci serverName="CICSQ2V5" connectionUrl="tcp://EBS-WSDEV2-2012.ad.xxxx.pri" portNumber="2006"/>
   </connectionFactory>

依赖注入中断。

CWNEN0030E: The server was unable to obtain an object instance for the java:comp/env/com.ibm.ctg.samples.liberty.JCAServlet/cf reference.  The exception message was: CWNEN1003E: The server was unable to find the eis/ECI binding with the javax.resource.cci.ConnectionFactory type for the java:comp/env/com.ibm.ctg.samples.liberty.JCAServlet/cf reference.

非常感谢

根据您的server.xml配置，Web应用程序没有从资源适配器加载InteractionSpec类所需的classloader定义。

因此应将其指定为

<webApplication id="jca-web" location="jca-web.war" name="jca-web">
   <classloader classProviderRef="eciResourceAdapter" />
</webApplication>

发布我解决该问题所遵循的过程。 如Trilarion和crshnburn所述，显然存在类版本冲突。

感谢您的帮助。

1安装新的Liberty配置文件。

2从RAR存档中提取cics.jar进行编译。

3不要在server.xml中包含jcaRemoteEci-1.0功能。

4使用以下server.xml：

<?xml version="1.0" encoding="UTF-8"?>
<server description="ejb server">

    <!-- Enable features -->
    <featureManager>
        <feature>javaee-7.0</feature>
        <feature>localConnector-1.0</feature>
    </featureManager>

    <!-- Encoded password can be generated using bin/securityUtility -->
    <keyStore password="change1me"/>

    <basicRegistry id="basic" realm="BasicRealm">
        <user name="user1" password="change1me"/>
    </basicRegistry>

    <!-- Automatically expand WAR files and EAR files -->
    <applicationManager autoExpand="true"/>

    <library id="ebsPropertiesFiles">
       <folder dir="C:\\ICBFiles\\Properties\\EBS" />
    </library>

    <!-- To access this server from a remote client add a host attribute to the following element, e.g. host="*" -->
    <httpEndpoint id="defaultHttpEndpoint"
                  httpPort="9080"
                  httpsPort="9443" />

    <!--The location of the cicseci.rar needs to be updated to the full path-->
    <resourceAdapter autoStart="true" id="eciResourceAdapter" location="C:\ICBFiles\SharedLibs\cicseci9200.rar"/>

    <connectionFactory id="cicsECI_CF" jndiName="eis/cicsECI_CF">
        <!--The properties need to be updated to the location of the CICS Transaction Gateway-->
        <properties.eciResourceAdapter connectionUrl="tcp://EBS-WSDEV2-2012.ad.aib.pri" portNumber="2006" ServerName="CICSUWV5"/>
    </connectionFactory>

    <enterpriseApplication id="icb-liberty-ear" location="icb-liberty-ear.ear" name="icb-liberty-ear">
       <classloader commonLibraryRef="ebsPropertiesFiles" classProviderRef="eciResourceAdapter"/>
    </enterpriseApplication>
</server>

4使用以下pom.xml。注意，cicseci是用“提供的”范围定义的，允许编译器依赖性，但避免打包到war存档中。
