Fast Object Database for Java - with JPA/JDO support

Can not connect to replication node


Hi, I tried to connect the database server using uri..

However the program emits error saying that no such Provider..

The code is below:

var uri = "objectdb://;user=asli-webmapper;password=admin1";

var emf = Persistence.createEntityManagerFactory(uri);

Error log:

bmpccdeMac-mini:mapper eko$  cd /Users/eko/work/asli/asli-java/mapper ; /usr/bin/env /Library/Java/JavaVirtualMachines/jdk-11.0.8.jdk/Contents/Home/bin/java -Dfile.encoding=UTF-8 @/var/folders/nd/0154lndn6tg_gd3c6857mt380000gp/T/cp_44eka4akdrg7edivffdip1wz0.argfile jp.asli.webmapper.WebMapperHttpServer

This error message is usually shown when the objectdb.jar file is not available in the classpath.

Thanks for your suggestion.. It solved my problem.

However, do  you have any clue on error below:


Please report this error on

com.objectdb.o.InternalException: null

Is the new stack trace related to replication?

Please provide more details, including whether it happens also after restarting the server and fixing the database.
