cant get arcgis runtime 9.3 to run sample jar file provided by Arcgis engine on unix

[nhieuduong]

so i have been trying to get this to work for weeks now, running into problem after problem.
Currently, im trying to run arcgis engine runtime 9.3 on red hat .

under root i get this error

Could not load native libraries. ArcGIS/bin should be added to LD_LIBRARY_PATH environment variable

java.lang.UnsatisfiedLinkError: /home/nhieuduong/arcgis/bin/libntvninv.so: libshlwapi.so: cannot open shared object file: No such file or directory.

ive checked and libntvninv.so is in the /home/nhieuduong/arcgis/bin directory. so is it saying that it cant find libshlwapi.so ? i followed all the procedures outlined by arcgis on there website. sourced the init_engine file and the init_java file and placed java home env variable in the java directory. my regisitration is complete. i have the correct licenses. did anyone encounter something similiar that can maybe shed some light as to what is going on?

Root is not needed. You should be using the same user that ArcGIS Engine Runtime was installed by.

[nhieuduong]

so does it mean that all the errors that im getting thru root are not the real cause but just superficial?

do i need to add arcgis/bin to LD_LIBRARY_PATH as some of the errors suggest? or adding JAVA_HOME/bin to PATH sufficient enough?

can we clear something up, am i suppose to be editing PATH or LD_LIBRARY_PATH? and who and what am i adding to PATH/LD_LIBRARY_PATH

sorry for the confusion

we are using arcgis runtime 9.3.1 . should i download the tar file in the link just in case?
