Subject:Re: OM 2.1 and Oracle JRE version
From:Manoel Campos da Silva Filho (

Hello guys. After a long, long time trying to install OM 2.0 and 2.1 (several months trying), now I finally had success.

So, I want to report the problem with the installation. How I reported at previous email, I was getting a "java.lang.NullPointerException ..." error when trying to install OM by the web interface.

At openmeetings.log I got several "org.apache.openjpa.persistence.PersistenceException: The column index is out of range: 2, number of columns: 1" error messages.

I understood the error, but didn't know why. I was sure that I had the correct pre-requisites and was following the correct installation steps (I already had installed OM 2.0 at other linux server).

After several tries, I resolved to try the command line tool.

The tool shown me a different error message (at a sql command): "unterminated string".

I didn't see this error at any log using the web interface installation. So, I suspected what was wrong: the use of backslash at SQL commands on PostgreSQL 9.1, because the postgresql standard_conforming_strings parameter was setted to "off". I changed the parameter to "on" and set escape_string_warning to "off" and solved the problem.

Thank you all for the help :) I hope my story can help other users

JDK7 works as expected also you need to inspect openmeetings.log to find the root cause

Hello Manoel,

OM 2.1 require JRE 1.6.

Hello, I'm trying to install OM 2.1 and I'm receiving the error below when I open http://myserver:5080/openmeetings/install

Does OM 2.1 require Oracle JRE 1.6 ou 1.7? At error page, I see that it uses Tomcat 7.

java.lang.NullPointerException javax.servlet.http.HttpServlet.service( javax.servlet.http.HttpServlet.service(
