I am new to liferay, Can anyone please suggest some way to generate the service.xml for existing database Discussion on Liferay Website . I hope people might have developed some way or liferay have developed some plugin for this.
I see no particular use in introducing servicebuilder to large existing databases: You can connect servicebuilder entities to "legacy datasources" or "legacy tables" (those make good search terms) but service.xml generation has not been done AFAIK.
Some problem with this approach are:
My recommendation is to rather have a proper interface on the existing business logic, e.g. Webservice, JSON, Rest, whatever is popular. Then use this interface in Liferay's portlets.
Another option might be to bring the existing persistence code into Liferay and just expose services without making use of the persistence features of Servicebuilder. For this you'd just define empty <entity> blocks (with names etc). This will generate the appropriate DoSomethingLocalService, but omit the persistence implementation - and you can wire your existing code in these services.
