Re: Access DODs from LAS


You proceeded exactly as you should have.  It is not that particular .xml file that is at fault as your server currently responds with "Connection refused" errors for any data request.  Hang on while I give you my blow-by-blow debugging session.

1) Your user interface works fine

So Tomcat and its interactions with MySQL are OK

2) I just tried 'las/server/ls.pl http://aquarius1.gsfc.nasa.gov/las-bin/LASserver.pl' to see if your data server is working.  It timed out with:

Request failed
<HEAD><TITLE>An Error Occurred</TITLE></HEAD>
<H1>An Error Occurred</H1>
500 Can't connect to aquarius1.gsfc.nasa.gov:80 (Timeout)

So it looks like your web server is down

3) Now I just tried to access your web server home page at http://aquarius1.gsfc.nasa.gov/ with my browser and got 'no response' message.

So your web server is indeed down.

Hi there,

I again need your help on how to access DODs data from LAS. Hope to have some hints, please.

As for a test, I did this:
../xml/perl/addXml.pl --out_inc las_master.xml dodstest.xml http://cola8.iges.org:9090/dods/agcm_anom_jan_h

I then included the dodstest.xml into my las.xml and did the genLas. In LAS interface I did have the COLA data on the list, which contains two variables: ssta and hca. However, when I try to view the data (xy slide for ssta and hca)  I got this error:

The following error occurred:

javax.servlet.ServletException: Connection refused
 at gov.noaa.pmel.tmap.FormFilter.doFilter(FormFilter.java:98)
 at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:213)
 at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:193)
 at gov.noaa.pmel.tmap.SessionFilter.doFilter(SessionFilter.java:272)
 at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:213)

Why the connection is refused? it should be ok since I have successfully generated the dodstest.xml file.
