[gradsusr] problem of station data in the GrADS data server

[Namba Takaya]

Dear Sir
I installed GDS in MAC OS X  10.6.3.(intell duo)  The grads version is v2.0.a9.javaa version is 1.6.0_17.
The GDS work properly with the ctl file/binary.But when I access the station data, the error message come listed below. I found probably the same problem in the grads previous mailing list in http://gradsusr.org/pipermail/gradsusr/2008-September/007531.html.Unfortunately, there is not enough information on it. I attach three logs files (console.out, gds.log, tomcat.xxxx.log) for more detailed information.Could you tell me how to solve this problem?
Best regards,Takaya NambaError {
