Import the certificates into Tomcat (JVM)

A Java TrustStore file holds certificates that authenticate other applications; for example, MySQL server, LDAP server. Using this file, OpenSpecimen will trust LDAP/MySQL as a legit partner.

The JVM (client), look up the certificates in its TrustStore. If the certificate or Certificate Authorities presented by the LDAP/MySQL is not in our TrustStore then the application gives an SSLHandshakeException and connection won’t be set up successfully.

Error:

Caused by: javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

Resolution:

1. Import the certificate file in keystore file using below command.

Example: keytool -importcert -alias ldap-certs -file /usr/local/openspecimen/certs/ldap.crt -keystore /usr/local/openspecimen/certs/ldap.keystore -storepass mypassword

2. Add this newly created truststore file into Tomcat (JVM).

Open the setenv.sh file present at $Tomcat/bin/ location and add below line in it.

Example: export JAVA_OPTS="$JAVA_OPTS -Djavax.net.ssl.trustStore=/usr/local/openspecimen/certs/ldap.keystore -Djavax.net.ssl.trustStorePassword=mypassword -server"

3. Once the configuraiton is done restart the Tomcat.
