Hi Roland,

Thank you very much for looking into it. You are right because I have another xml file with a missing time prior this ASCAT xml file.

So it would not allow me to find the time. I fixed it, then both the datasets are working fine now.

I have another problem about time range if that is too big. For example, this SIM2bl dataset with 21000 years.

http://apdrc.soest.hawaii.edu/dods/public_data/Paleoclimate_modeling/ECBilt-CLIO/SIM2bl/atm-annual/single_level

Time: 00Z01JAN0000 to 00Z01JAN20999 (21000 points, avg. res. 365.243 days)

I used the addXML to create the xml file.

I worked in LAS6 and loaded fast, but it loaded kind of slow or not responded with some pop-up _javascript_ warning messages in LAS 7.3.

The pop-up warning showed:

“A script on this page may be busy, or it may have stopped responding. You can stop the script now, or you can continue to see if the script will complete.”

Do you have another method loading the time range with input text box rather than scroll menu?

Thanks,

Kin

Hi,

There must be something else wrong with your configuration. I have installed this data set on my server and it seems to work.

If you can, I suggest the following:

Save a copy and then remove your $TOMCAT_HOME/content/las/conf/server directory.
Do a fresh install of LAS installing the sample data sets.
Add the configuration for this data set into the las.xml config that gets generated by the install.
Once that is working you can configure in your other data sets and add any customizations from your saved conf/server directory.

Hi LAS developers,

I tried to test LAS 7.3 with Ferret 6.72.

I found out this ASCAT dataset would not work with LAS 7.3.

http://apdrc.soest.hawaii.edu/dods/public_data/satellite_product/ASCAT/daily

Time: 00Z03MAR2009 to 00Z28FEB2011 (728 points, avg. res. 1.0 days)

It broke on the getOperations.do and getVariables.do with Null Pointer Exception.

[16/Sep/2011:10:36:30 -1000] "GET /las/getOperations.do?xpath=/lasdata/datasets/id-e2534a1370/variables/uwnd-id-e2534a1370

{"operations":{"error":"java.lang.NullPointerException","status":"error"}}

I tried to debug. I found out this:
