P Paul Brennan Member Jul 1, 2020 #1 I developed an APP with Jackaccess that has been working flawlessly with any Android version up to version 8. But it doesn't work under versions 9 and 10. The error showed in debug mode refers to Java: java.lang.NoClassDefFoundError: Failed resolution of: Lorg/apache/commons/logging/LogFactory; at com.healthmarketscience.jackcess.Database.<clinit>(Database.java:92) at com.healthmarketscience.jackcess.Database.open(Database.java:509) at anywheresoftware.b4a.objects.JackcessDatabase.Open(JackcessDatabase.java:170) and so on. I know that there was no plan to develop a new Jackaccess library for B4A, but migrating to SQLite or any other database manager would be a nightmare and a high consumming task to me and everyone who has used Jackaccess so far. Could it be possible to ask (even beg) the Jackaccess creator to release a new version that works with Android 9 and 10? Thanks in advance from a MS-Access lover.

P Paul Brennan Member Jul 2, 2020 #3 Hi Erel, and thank you for your response. I forgot to mention that my project has been developed usin B4A, not B4X. Having taken a look to the link you sent me it seems that these are libraries for B4X. Is that correct? Thanks again for your help. Last edited: Jul 2, 2020 Upvote 0

udg Expert Licensed User Longtime User Jul 2, 2020 #4 Hi Paul, generally speaking, B4X is the language while B4A,B4J,B4i,B4R are the products (compilers) for their respective platforms. Upvote 0

P Paul Brennan Member Jul 2, 2020 #6 It's clear. So I'm rewriting my question: is it possible to use UcanAccess.jar library within B4R? Upvote 0
DonManfred Expert Licensed User Longtime User Jul 2, 2020 #7 This is the B4A part of the Forum. Only B4A questions should be asked here. For B4R you should post your question in B4R Forum. I guess the answer is no as B4R does not depend on JAVA. So adding any jar is not possible. Upvote 0

P Paul Brennan Member Jul 2, 2020 #10 My mistake, it's pretty easy to type incorrectly the different compilers. I meant B4A, not B4R, sorry for the inconveniences. Upvote 0
