problem with GLPK 4.8 JNI

hi, i've been using the glpk jni 4.8 for solving my linear programming problems.
the main interface used to solve LP is the GLPKSolver interface.

when the gc tries to reclaim the memory from the GLPKSolver object....an exception occurs saying
" ufree: ptr ..... memory allocation error"

this prevents me from solving large number of problems continuously.
the occurance time of the error is uneven as it occurs when the gc runs.

i am using windows xp, java 1.6, glpk_jni 4.8.
please help...

radio button not working with panelgrid

here either the radio button group works fine or the rest of the command links and buttons work fine....
not both....
if the radio button group is cut then the rest of the command links triggers the action handlers but if the radiobutton is present then none of the action is triggered.....
if the menulist rendering is made static then the rest of the code works fine....but if it is dynamic then the command buttons and links in rest of the code does not work....

typically illogical problem....please help...

invalid cursor state

when you get the result data into your ResultSet, the cursor is placed before the first row...hence you need to use the next method on the resultset object to place the cursor on the correct position and then try extracting data from it
cheers!!
