无法在WSO2 6.1.0上部署twitter连接器

Question

我厌倦了在WSO2 6.1.0上部署示例twitter连接器。一旦上传了zip文件，我就会得到成功上传文件的消息，刷新页面以查看连接器，但是连接器列表没有显示连接器。

在系统日志中，我看到以下错误

TID-1234 2017-05-17 12:40:03,321错误{org.apache.synapse.deployers.LibraryArtifactDeployer} -突触伪影的部署失败用于synapse libray at : C:\WSO2 2企业Integrator\wso2ei-6.1.0\wso2ei-6.1.0\repository\deployment\server\synapse-libs\twitter-connector-1.0.0.zip :错误时提取同步库:twitter-连接器-1.0.0.zip org.apache.synapse.libraries.util.LibDeployerUtils.extractSynapseLib(LibDeployerUtils.java:426) org.apache.synapse.libraries.util.LibDeployerUtils.createSynapseLibrary(LibDeployerUtils.java:65) org.apache.synapse.deployers.LibraryArtifactDeployer.deploy(LibraryArtifactDeployer.java:60) org.apache.axis2.deployment.repository.util.DeploymentFileData.deploy(DeploymentFileData.java:136) org.apache.axis2.deployment.DeploymentEngine.doDeploy(DeploymentEngine.java:807) org.apache.axis2.deployment.repository.util.WSInfoList.update(WSInfoList.java:144) org.apache.axis2.deployment.RepositoryListener.update(RepositoryListener.java:377) org.apache.axis2.deployment.RepositoryListener.checkServices(RepositoryListener.java:254) org.apache.axis2.deployment.RepositoryListener.startListener(RepositoryListener.java:371) org.apache.axis2.deployment.scheduler.SchedulerTask.checkRepository(SchedulerTask.java:59) org.apache.axis2.deployment.scheduler.SchedulerTask.run(SchedulerTask.java:67) org.wso2.carbon.core.deployment.CarbonDeploymentSchedulerTask.runAxisDeployment(CarbonDeploymentSchedulerTask.java:93) org.wso2.carbon.core.deployment.CarbonDeploymentSchedulerTask.run(CarbonDeploymentSchedulerTask.java:138) java.util.concurrent.Executors$RunnableAdapterjava.util.concurrent.FutureTask.runAndReset(FutureTask.java:308) java.util.concurrent.ScheduledThreadPoolExecutor$ScheduledFutureTask.access$301(ScheduledThreadPoolExecutor.java:180) java.util.concurrent.ScheduledThreadPoolExecutor$ScheduledFutureTask.run(ScheduledThreadPoolExecutor.java:294) java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1142) java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617) .call(Executors.java:511) java.lang.Thread.run(Thread.java:745)

我试着构建twitter-连接器-1.0.0和2.0.0。1.0.0连接器文件

`<?xml version="1.0" encoding="UTF-8"?>
<connector>
    <component name="twitter" package="org.wso2.carbon.connector">
        <dependency component="twitter_config" />

2.0.0连接器文件

 <connector>
    <component name="twitter" package="org.wso2.carbon.connectors">

Answer 1

经过一些调查，我发现这个问题与WSO2的安装有关。无法安装twitter连接器的环境是使用postgres数据库安装的，如果我使用WSO2数据库，就可以安装和使用twitter连接器。

我希望这能帮上忙。

谢谢。
