Re: Need help to locate HSQLDB in Base
We have been looking on different kind of databses to embed under libreoffice base. Some few ones we like are: Friebird (but has some issues with embedding it under linux it doesnt work easily. Not only this you will have to embed Classic under linux and its architecture is not suitable for an application like base and it wont be 'pure' embedded server) MySQL/ libmysqld (GPL issue. What i have derived from difference between LGPL and GPL licenses i have come to conclusion that if we use libmysqld and as .DLL / .SO there wont be any license issue as Base being FOSS free open source software has the right to use it libmysld in it if we mention that this particular library is under GPL license and no commercial organisation can use it without permission of Oracle without changing our license. But we cannot amend any code part of libmysqld if we do this then we will be owner of of that amended library and according to LGPL commercial organisation will be able to use it. So to do that libre will have to come to GPL license. What we derived to make mysql as embedded in base it would had to be amended a little run .ODB files and store databases in .ODB files. If we are wrong or we can avoid this amendment then i think best choice is mysqld. Its footprint is not huge and provides nearly every thing one can need. High performance SQL standards etc.) We can also embed PostgreSQL. An embedded version is not available but we can pack the binaries of postgresql with it. Run it when application starts in a new thread and bind it listen to to only local host. Then kill the process and wait the thread to join before exiting the application. It can also resolve many major f*unctionalities and platform issues.)* - Note: if we embed MySQL or PostgreSQL the work would be very less also. As their drivers are already written. Oracle's berkley db is also very good option for embedded as it is open source. Its an SQL dbms but is not relational dbms.) SQLite already voted out. Rest all DBMS that can be embedded i saw are under commercial license or only runs in Windows based applications).

Re: Need help to locate HSQLDB in Base
But again if we embed PostgreSQL the issue will come again on running .ODB files.

Re: Base project in GSoC 2012
The IRC channel is dead Mr. Mutthu the mentor of this project is not replying from his official email. The IRC channel is dead also. I am really intrested in this project and i am already doing this stuff in research center in my university. I can do it. Please can anybody help me contacting the mentor is some other way. I need to get in touch with him. On Fri, Mar 23, 2012 at 11:30 PM, Waqas Iftikhar coldheart...@gmail.comwrote: I am writing about the LibreOffice Base project in GSoC 2012.

Re: Base project in GSoC 2012
I dont know where can i contact Mr. Mutthu the mentor of this project in GSoC can any body help? I have already build LibreOffice and now gonna start studying its code base where it connects with HSQLDB to get information about it.
