Re: Problems setting up insitu data access

[Joe McLean <joe.mclean@xxxxxxxx>]

Hi Andrew,
Just want to make sure that you modified the ui.xml as instructed in las/contrib/insitu/INSTRUCTIONS.txt
------------------------------------------------------------
<!DOCTYPE spec SYSTEM "spec.dtd" [

<!ENTITY StdOptions SYSTEM "options.xml">

<!-- general insitu UI behavior and options -->
<!ENTITY insitu_ui SYSTEM "insitu_ui.xml">
<!ENTITY insitu_options SYSTEM "insitu_options.xml">

<!-- UI elements specific to the LAS_insitu_demo -->
<!ENTITY insitu_demo_ui SYSTEM "insitu_demo_ui.xml">

]>

<lasui title="YOUR TITLE">
    &StdOptions;
    &insitu_ui;
    &insitu_options;
    &insitu_demo_ui;

...

A little more information. 

In las.xml, in the operations element, I have this:
 <!-- Operations supported by this server -->
 <operations url="" class="moz-txt-link-rfc2396E" href="">"http://prey.shore.mbari.org/las-bin/LASserver.pl">
   &operations;
   &insitu_operations;
 </operations>

when I insert a spelling error into the &operations; reference and run $LAS/server/make I get an error in the make process. However, when I insert a spelling error in &insitu_operations I get nothing, still the same error from the UI as before, but nothing from make.

My declaration of the entity looks fine:
<!-- Declaration of operations files to be included -->
<!ENTITY operations SYSTEM "operations.xml">
<!ENTITY insitu_operations SYSTEM "insitu_operations.xml">

And the insitu_operations.xml file is in the server directory, I even opened up the permissions on it, in case that was the problem. For whatever reason, LAS isn't seeing that insitu_operations entity...

Hi Roland, 

Thanks for your reply. I'm pretty sure I've got the proper 
references to the insitu_operations.xml in the las.xml file 
as well as the insitu_operations.xml file in the server 
directory. I double-checked those steps of the setup process 
after I received your email, and I made sure to verify that I 
followed the directions laid out in the documentation. I'm 
still getting the same error though. I'm going to go back 
through one more time and make sure my configuration follows 
the documentation, any other suggestions?

Thanks for explaining the path mapping to element 
hierarchies, that makes a lot more sense.

Cheers,
Andrew

Andrew,

You need to make sure the file insitu_operations.xml is in your 
$LAS_HOME/server directory.  If not copy it over from 
contrib/insitu/server/.

Then add a reference to it in the <operations> element of 
your las.xml 
file.  E.g.

<!ENTITY InsituOperations SYSTEM "insitu_operations.xml">
...
  <operations url="" class="moz-txt-link-rfc2396E" href="">"http://server.com/las-bin/LASserver.pl">
   &StdOperations;
   &InsituOperations;
   </operations>

By the way, the paths /lasdata/operations/insitu_data_cdf and 
the like 
refer to element hierarchies in the XML document, not Unix file 
systems.  The software is looking for a definition in an element 
hierarchy like this:
<lasdata>
<operations ...>
<insitu_data_cdf.../>
...
</operations>
</lasdata>

which you will be supplying by installing the reference to the 
insitu_operations.xml file.

Hello fellow LAS users,

I'm working on serving non-gridded data from a database and 
        

as a first step I've been trying to setup the insitu dataset 
that comes with the LAS distribution. I'm using LAS version 
6.4.1 on a itanium 64 running Redhat 9. I went through the 
'make insitu' process and everything seemed to install fine. 
However, when I try to get any sort of output from the the 
insitu dataset I get an error.
      

With the following options selected:
Select view:	Longitude-Depth Sections
Select output:	ASCII table
Select region:	Full Region
Select time range:  	01 Jan 1986  to 31 Dec 1988
Select depth range: 	0 to 2000
Select Constraints:	None

Rather than getting the expected ASCII table, I receive the 
        

following error:
      

LAS Error
The following error message was received from LAS:
Can't find match target '/lasdata/operations/insitu_data' at 
        

'insitu_data' at ../xml/perl/LAS.pm line 613
      

Depending on the selected view and selected output, I get 
        

other similar errors:
      

LAS Error
The following error message was received from LAS:
Can't find match target 
        

'/lasdata/operations/insitu_data_cdf' at 'insitu_data_cdf' at 
../xml/perl/LAS.pm line 613
      

LAS Error
The following error message was received from LAS:
Can't find match target '/lasdata/operations/insitu_meta_xy' 
        

at 'insitu_meta_xy' at ../xml/perl/LAS.pm line 613
      

Looks like I've got some sort of path configuration problem, 
        

but I can't find any documentation on how to set up the 
lasdata path. Additionally, I can't find an "operations" 
directory within my LAS installation. I see a .jnl file named 
insitu_meta_xy in $LASHOME/server/jnls/insitu/ is this what 
LAS is looking for? I don't see any files named insitu_data 
or insitu_data_cdf anywhere in the $LASHOME directory.
      

Any thoughts, suggestions?

Thanks,
Andrew
