[rules-users] Memory leak when deploying to Maven repository?

[Sandjaja, Dominik]

Hello,

our scenario is like this:
>From our customer, we get an Excel file which contains something rule-like which we convert into actual Drools rule strings. Those, we want to deploy in our local Maven repository (the one being used by Drools/KIE/Maven) as an actual artifact. This allows us later, to create new rules with KIE-WB, which are then deployed into the same repository, but with a higher artifact version. The actual application can then initially, when it doesn't have a connection to KIE-WB, use the rules created from the Excel sheet. In a second step, it can later get a more current rule artifact from the KIE-WB repository.

This is why we create an actual artifact out of the Excel sheet. That process takes a while, so we do it in the startup listener.

As far as I understand it and as far as I could see it on the filesystem, when I build a KieModule programmatically, it is not persisted anywhere and it is lost on restart of the system. That is why I wanted to explicitly persist it with the Aether facilities, as depicted in my previous post. If I do not do that and if I then check at startup if the artifact version does exist, I get back a "false" and it is created again - which takes quite some time. This is the reason why I want to store my created artifact in the local, persistent repository.

Am I getting something wrong? Is the artifact already stored somewhere?

I hope my intentions are a bit clearer now ...

Thanks in advance!
Dominik

Hi Dominik,

I'm honestly not understanding why you're creating a kieModule and most important why you're deploying it on maven in a ServletContextListener, but I am guessing you're doing this only to demonstrate the problem. Also be aware that for doing so you're using some drools internal API and these API aren't guaranteed to be stable.

However every time you build a kieModule or you load it from a maven repo, it is stored in the KieRepository. If you need to remove it from there you can do this explicitly by using the KieRepository.removeKieModule(ReleaseId)
method.

I hope this helps,
Mario
