Subject Please help me to build Derby in Eclipse..
Date Sat, 12 Sep 2009 04:08:36 GMT
Hi all,

I really dont know I am in right place or not. Please excuse me if I am in
worng place and please direct me to  the right place.

I am Ajith from India and working as a software engineer.

Now a days I am trying to build a website using java and Derby as the
backend.
I choose eclipse as the development environment to do this.

I was tring to build Derby in eclipse as explained in the page :
http://wiki.apache.org/db-derby/BuildingDerby

I succeded upto point 4 but When i try to build source for the Derby it is
causing some problem.
I am very new to java and all so it is really confusing to me hence I am
seeking your help to sort it out.

I executed the command :- ant -quiet clobber successfully
But the command :- ant -quiet buildsource  failed with the following errors
:

------------------------------
----------------------------------------------------------------------------------------------------------------------------------------------------------------
[root@localhost Demo1]# ant -quiet buildsource
[setJdkProperties] Unrecognized VM vendor: 'Free Software Foundation, Inc.'
[setJdkProperties] An attempt to configure the required JDKs will be made,
but the build may fail.
[setJdkProperties] In case of problems:
[setJdkProperties]   - consult BUILDING.html and set the required properties
manually
[setJdkProperties]   - set the property printCompilerProperties to true and
ask the Derby development community for help
[setJdkProperties]     (please provide the debug output from running ant)
