2PC transactions (cross transactions) in GlassFish 5

Question

Does someone know if GlassFish 5 has support to use global transactions with 2PC (XA protocol)? but without install extra tools.

I have looked for information in the page of GlassFish "The Open Source Java EE Reference Implementation" where I downloaded the app server (and in other pages) but I have not had luck.

I try doing transactions in two microservices that insert two values in the data base. I have configured the GlassFish's JNDI with "com.mysql.jdbc.jdbc2.optional.MysqlXADataSource" and it looks like working, but when I check the data base only is added a value of one service. (the global transactions with 2PC does not work). I begin to think that GlassFish does not have support for 2PC.

I have read that it can do it with tomcat, but i need to add tools like atomikos, bitronix, etc. The idea is can do it with glassfish with out install nothing more.

Regards.

Glassfish 5 supports transactions using XA datasources. You can create a program that executes transactions combining operations on multiple databases. For instance, you can create a transaction that performs operations into Oracle and IBM DB2 databases. If one of operations in the transaction fails, the other operations (in the same and in the other databases) will be not executed or rollbacked.

If your program invokes a REST/web service in a transaction, the operations performed by the other REST/webservice do not join to the transaction. An error in the program will not produce a rollback in the operations performed by the already invoked REST/webservice.
