Most of the time developers likes manage their application configuration on separate file, which contains name value pair. In my current project one of my team member also implements such a configuration through Spring. Put the file on Jboss %jboss-as%/server/xyz/conf folder which will picked by the spring on the startup of the server. I have asked him, what should i do to change the value of the configuration. He replied, you have to change the file and restart the server or start and stop the application ))). Certainly we face a lof of times these type of use cases. I told him about JMX and decided to make some quick change on code. Todays post is about JMX. For more information about JMX use cases, check the following links JMX use cases. At first we will create one interface and his implements, which will be our resource to manage by JMX. here is the fragment code of the classes: public interface ConfigMBean { public void setURL(String url); public String getURL(); ...

Nginx is a free, open-source, high-performance HTTP server and reverse proxy server, which can be use with WebLogic application server to cache static page. It's also able to load balancing between servers. However nginx default proxy pass configuration not working properly with WebLogic server, because WebLogic server reset his http header which changes host and port. Here is the configuration for Ngnix proxy pass: proxy_cache_path usr/apps/nignx/nginx-1.1.12/cache/ levels=1:2 keys_zone=data-cache:8m max_size=1000m inactive=600m; proxy_temp_path usr/apps/nignx/nginx-1.1.12/cache/temp; upstream osbapp{ server 192.168.52.101:7001; server 192.168.52.101:7002; } server { listen 8001; server_name 192.168.52.103; location / { proxy_set_header Host $http_host; # set the parameter for fine granned header proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy...

Last week Sonar announced their new version 2.8 with a few new features and bug fixes. The main new feature is the support of custom code review. Crucible and Review board are another alternative code review system. Sonar come across with code coverage and review in one system, which is easy to maintain with small effort. As usual sonar administrator must create users to assign tasks and collaborations. Sonar provide LDAP plugin which enables the delegation of Sonar authentication to an external system. Currently LDAP plugin supports LDAP and Active directory. In our corporation we are using active directory and first of all i tried to configure the LADP plugin. LDAP plugin wiki fully describes the installation of the plugin with LDAP system but poorly with AD. With some effort with my boss we were able to configure the plugin with our AD system. Follows i am sharing the configuration: #------------------- # Sonar LDAP Plugin #------------------- # IMPORTANT : before activation,...

Apache maven is one of the popular tool for building and managing java projects. Based on the concept of a project object model (POM), Maven can manage a project's build, reporting and documentation from a central piece of information. However when you have projects with multiple modules, it follows some issue when you compiling your project. One of them is incremental building, which means when you updates your project from the version control, you have to build the entire system by command mvn clean install. Consider the following maven project structure: IncrementalBuild |_ _ test-api |_ _ test-api-impl |_ _ test-donothing where module test-api-impl dependent on module test-api. Whenever we will make some change on module test-api, we have to recompile and build the module test-api-impl. If we will enter the command mvn install module test-api-impl will not get the updated version from the module test-api. You have to run command mvn clean install which will rebuild the...

After the Javaone conference in Moscow, i have found some free hours to play with Sonar . Here is a quick steps to start analyzing with ANT projects. Sonar provides Analyze with ANT document to play around with ANT, i have just modify some parts. Here is it. 1) Download the Sonar Ant Task and put it in your ${ANT_HOME}/lib directory 2) Modify your ANT build.xml as follows: <?xml version = '1.0' encoding = 'windows-1251'?> <project name="abc" default="build" basedir="."> <!-- Define the Sonar task if this hasn't been done in a common script --> <taskdef uri="antlib:org.sonar.ant" resource="org/sonar/ant/antlib.xml"> <classpath path="E:\java\ant\1.8\apache-ant-1.8.0\lib" /> </taskdef> <!-- Out-of-the-box those parameters are optional --> <property name="sonar.jdbc.url" value="jdbc:oracle:thin:@xyz/sirius.xyz" /> <property na...
