I am moving the comment I made here ([whatever not displayed][1]) to a real question:

I am trying to use **backlocate** to get the genomic position (say, on hg19) from a mutation given with the classic nomenclature: p.D240Y (gene EIF4G1).

There are two versions of the tool available:

 - one from [github][2]
 - one from [google code][3] (from my understanding, this is the one intended for distribution)

I tried cloning the github repository and compiling the 'jsandbox' tools. However, I get a `java.lang.ClassNotFoundException: com.mysql.jdbc.Driver` error that I couldn't get fixed even when installing 'Mysql Connector Driver' and adding it to my `$CLASSPATH`.

After having tried a lot of things, I realized there was a version apparently made for distribution (in the 'variationtoolkit' from google code). I checked-out the complete toolkit, but the compilation fails due to some unmet dependencies that I can't seem to install properly (tabix).

Has anyone had experience using **backlocate**, or would @Pierre have some ideas on how to fix these errors?

Hi leonor,

As its seems that using the sql driver is a problem for many users, I've just moved my code to only use local resources (https://github.com/lindenb/jvarkit/commit/f8cb884544354a7c62d4440b58e8e74c2045a6cd). You don't need the jdbc driver anymore :

Download a fresh copy of jvarkit and compile again

```
