I think the problem is your LD_LIBRARAY_PATH and LD_LIBRARY32_PATH setting are not right. Do you add below line?: omni/lib/mips_irix_6.5_n32. _omniidlmodule.so should be there. Good luck, wish omniORB living better in the future, shifeng __________________________________________________ Do You Yahoo!? Yahoo! Tax Center - online filing with TurboTax http://taxes.yahoo.com/
