Unresolved requirement: osgi.component

由 核能气质少年 提交于 2019-12-11 00:49:59
问题 I'm trying to develop onto Karaf an OSGi WAB containing a REST API and a call from a custom-made service. However, for some weird reason, the OSGi framework complains about an unsatisfied capability, osgi.component . I would like to know : How can I solve this issue? What is osgi.component bundle? Why is needed? Why maven-bundle-plugin (thereby also bnd), declares it inside the entry "Require-Capability"? If I need to install it on the OSGi framework, where may I find it? Some additional

OSGi Declarative services filter references at runtime

问题 I've been trying some examples with OSGi Declarative Services (among other things, such as Blueprint) on Karaf. The problem I am trying to solve now, is how to get references to certain services at runtime (so annotations and/or XML are not really an option here) I will explain my use case: I am trying to design (so far only in my head, that's why I am still only experimenting with OSGi :) ) a system to control certain automation processes in industry.

How to deploy a karaf feature from a local maven repository?

由 耗尽温柔 提交于 2019-12-07 08:30:38
问题 I've created by first project for karaf (4.0.1). So far I've got the following: an application bundle built with the maven-bundle-plugin . There are going to be more... a karaf feature created with the karaf-maven-plugin . a karaf-assembly created with the same plugin So I'm ready to deliver to the customer - but I'm stuck over the development process. This question answered almost all my remaining questions save one: After having built my project by running maven install I think I should be

Can't capture Apache Karaf client output

由 一个人想着一个人 提交于 2019-12-07 03:09:54
问题 I started Apache Karaf 3.0.0 in server mode using $KARAF_HOME/bin/start in CentOS 6.5. Then I wanted to run several commands using $KARAF_HOME/bin/client and also capture the output of these commands, so as to make sure the commands ran successfully. The output did get spit out on my console but I was never able to redirect it into a file. Seems like Karaf doesn't write anything to the output stream or error stream. I tried the following: [apache-karaf-3.0.0]$ ./bin/start clean [apache-karaf

kettle 大数据插件操作相关问题

一、hadoop 没有权限的解决方案 原文： http://kcd.nivalsoul.cn/article/1545533237270 问题 在 windows 上使用 kettle 连接 hadoop 写文件的时候，默认使用的是本机登录用户作为文件属主访问 HDFS 文件的，如果目标路径权限不允许，就会报错。 解决方案 1、修改 HDFS 目录权限 使用 HDFS 管理员登录将相关目录设置为所有人可写，比如 777 权限 2、在 kettle 中指定操作 HDFS 的用户 由于 HDFS 的 Java API 访问是通过获取 HADOOP_USER_NAME 这个变量来设置用户的，所以可以手动设置该值为 HDFS 上有权限的用户名即可。 1）通过在 Spoon.bat 中设置 在 set OPT= 这一行后面提添加内容： “-DHADOOP_USER_NAME=yourHdfsUser” 2）如果是 Java 代码，可以通过如下方式设置 System.setProperty("HADOOP_USER_NAME", "yourHdfsUser"); //指定属主 二、Linux上执行hdfs文件输出路径不正确 问题：可能创建了文件没有写数据，可能写到linux本地文件路径下，可以按如下设置试试： 在spoon.sh下修改参数 opt字符串里增加 -Dpentaho.karaf
