Hi Kanchibhotla Dheeraj‌,

i think the best way to use this libraries is to add them to your local maven repository:

mvn install:install-file -Dfile=<path_to_project>\libraries\myJsonParser.jar

-DgroupId=com.myjsonparser -DartifactId=myjsonparser -Dversion=0.1 -Dpackaging=JAR

It is also important to make sure, that this libraries will be added to your target-JAR that will be added to the GeoEvent Server. I use the Maven Bundle Plugin for that:

Apache Felix - Apache Felix Maven Bundle Plugin (BND) 

So the Plugin Part of your POM could look like this:

<plugins>
   <plugin>
    <groupId>org.apache.felix</groupId>
    <artifactId>maven-bundle-plugin</artifactId>
    <version>3.0.0</version>
    <extensions>true</extensions>
    <configuration>
     <instructions>
      <Bundle-SymbolicName>${project.groupId}.${project.artifactId}</Bundle-SymbolicName>
      <Bundle-ContactAddress>${sdk.contact.address}</Bundle-ContactAddress>
      <Bundle-Version>${project.version}</Bundle-Version>
      <Export-Package/>
      <Private-Package>org.foo.myproject.*</Private-Package>
      <Import-Package>*;resolution:=optional</Import-Package>          
      <Embed-Dependency>*;scope=compile|runtime;inline=true</Embed-Dependency>
      <Embed-Transitive>true</Embed-Transitive>  
     </instructions>
    </configuration>
   </plugin>    
 </plugins>

Best, 

Stefan

Hi Stefan,

I've added my external jars to the local maven repository. When I build the JAR using Felix plugin, JAR size becoming huge(7.5MB) which comprises all the classes. But Geo Event server is not accepting JAR more than 1MB.

Hi Kanchibhotla Dheeraj‌,

where did you get this 1 MB limit from? I have a lot of connectors and processors that are up to 5.4 MB. They are all working fine. What error message do you get?

Best Stefan
