ATG Which version

This tool is very useful in ATG to find the version and location (JAR file path) of any particular class:

ATG Colorizer: libstdc++.so.6: cannot open shared object file: No such file or directory

I was in the middle of my ATG local dev environment setup and started to see an error with small application ATG Colorizer:

libstdc++.so.6: cannot open shared object file: No such file or directory

I tried installing the library as I have done in the past, but somehow my new Ubuntu stopped liking the old install recipe. After checking the web for a while I found a way she liked: 

apt-get install lib32stdc++6

ATG: Template Error: category error 2

I started getting this error after a merge of code. No clue why this happened but it was impeding my work.

The CategoryLookup droplet (/atg/commerce/catalog/CategoryLookup) was the one failing . So I turned on debug mode to have more information. I got this:

14:01:43,960 INFO  [CategoryLookup] DEBUG Find item: id=BRAND_OPTIMUM; type=category
14:01:43,961 INFO  [CategoryLookup] DEBUG Item Found:category:BRAND_OPTIMUM
14:01:43,961 INFO  [CategoryLookup] DEBUG Is item in catalog catalog:masterCatalog
14:01:43,961 INFO  [CategoryLookup] DEBUG This item is not in the correct catalog.

A more expert person  on ATG told me there is a catalog maintenance page that is used to solve this kind of issues:

Basic Catalog Maintenance

http://localhost:8080/dyn/admin/atg/commerce/admin/en/maintenance/startService.jhtml?process=BasicMaintProcess

Basically, I just ran the process and issues were solved.

Flyway: No enum const class com.googlecode.flyway.core.api.MigrationState.SUCCESS

This exception thrown by Flyway:

happens because an invalid value in the column state. In my case it was failing because of an extra blank space I didn't notice.

Juniper VPN: sysdeps.error Failed to open /etc/resolv.conf with error 2 (sysdeps.cpp:715)

In my work we use a Juniper client for the VPN connection. Suddenly, I started getting problems to connect. It was like it was going to connect normally but at the end it was exiting like if I was doing it, showing the message that connection was closed successfully. 

Checking the logs I realized of this error:

ncsvc[p10461.t10461] sysdeps.error Failed to open /etc/resolv.conf with error 2 (sysdeps.cpp:715)

I went to check, and effectively this file  /etc/resolv.conf didn't exist. So I created an empty one (in my case it was a broken symlink). And voilà! Problem solved.
