Re: Error occurring in dods.dap.Parser

T,

Well. The problem is in your Dataset name:
} stream=ocea,param=200,DATE=20000101,TIME=0000,STEP=0,EXPVER=0oc7,CLASS =RD,TYPE=AN,NUMBER=0,METHOD=0,LEVELIST=7.000,LEVTYPE=DP,REPRES=LL,DOMA IN=G,salinity.nc; 

The parser is barfing on the first "=" character (Line 58, column 9)
James? Is this in any way a legal name? If so, how does he need to "escape" the "=" (and possibly the ",") characters?
You could escape the '=' and ',' using the HTTP %<hex digit><hex digit> notation, I think. When the Java DAP 2.0 parser was written we had not encountered file names that broke the 'C identifier' mold. But that was just around the corner... Anyway, the C++ code lets just about anything be a file name. I'd try the escaping scheme and see how it works. 

James
PS. I just checked the DDS parser and it will grok the percent sign, so you should be OK using that to signal the start of the escape sequence.

Bingo. Known problem. Can you send me the DDS, or is it automatically generated (and thus it never actually makes it through the system)? 

Or, can you send a list of all the filenames and variable names?


Here 'tis. Hope your system can handle long filenames! :)
The netCDF file gets generated on the fly based on the parameters you see encoded in the filename.
Does anyone know if this error related to java code, or the structure of a netCDF file, or the filename or what? To what is "line 58, column 9" referring - the .java file, the netCDF file, or something else entirely? 


That's where in the DDS or DAS the parser is crapping out.


Cool. Looks like it doesn't like the '=' character in some places.
