How to import certificate to java key store

Background: There is a SLDAP(ldap over ssl) server, I would like to use jmeter ldap sampler to test authentication.

Target: I would like to test the ldap ssl connection
             This is involved with cert import to java key store

Below is the steps;
1. copy the cert file from ldap server to local
scp <username>@<ldap server>:/etc/openldap/cacerts/cacert.pem ./

2. import certificate into Java Key Store (JKS)
sudo keytool -import -alias afiliasldap1 -keystore cacerts -file /tmp/cacert.pem
Note: input keystore pass: changeit
Note: on jvm, location for cert: /usr/lib/jvm/java-7-openjdk-amd64/jre/lib/security

3. Verify the import done successfully by showing the cert content:
keytool -list -v -alias afiliasldap1 -keystore cacerts -storepass changeit

In step3, you will see cert content shown, means import is done successfully

Now you can proceed to use your ldap sampler for ldap over ssl testing
Ensure that
– select “Use Secure LDAP Protocal” in LDAP thread bind
– and use ssl port(default 636) in LDAP Request Defaults

 

Maven step by step

1. Install Maven

2. Create a project
run comand below
‘mvn archetype:generate -DgroupId=com.mycompany.app -DartifactId=my-app -DarchetypeArtifactId=maven-archetype-quickstart -DinteractiveMode=false’

3. cd my-app
will see paths below
my-app
|– pom.xml
`– src
|– main
|   `– java
|       `– com
|           `– mycompany
|               `– app
|                   `– App.java
`– test
`– java
`– com
`– mycompany
`– app
`– AppTest.java

4. Build the project
run below command
‘mvn package’

5. run command
‘java -cp target/my-app-1.0-SNAPSHOT.jar com.mycompany.app.App’
will got command line output ‘Hellow World!’

Further
To make this project work with eclipse

6. cd my-app
modify pom.xml
– modify junit version from 3.8.1 to 4.1
–  add this for JDK 5.0 support as below:
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<configuration>
<source>1.5</source>
<target>1.5</target>
</configuration>
</plugin>
</plugins>
</build>

7. mvn eclipse:eclipse -DdownloadSource
8. open eclipse, File > import
import existing maven project

What is Maven:

what is POM:

Maven repository: to search component groupid artifact id and version info
http://mvnrepository.com/
for example: search sl4j in the above site, can find out below information that needed to add to POM.xml dependency section
<dependency>
<groupId>org.grlea.log.adapters</groupId>
<artifactId>simple-log-sl4j</artifactId>
<version>1.7</version>
</dependency>
Maven dependency scope types:
<scope>test</scope>
<scope>compile</scope>
<scope>provided</scope>

Whenever POM.xml is updated, run ‘mvn package’
