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 org.apache.velocity.tools.view.VelocityView.performMerge(VelocityView.java:942) ..." 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 admin.sh 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 On Mon, Jun 3, 2013 at 12:15 PM, Holger Schranz <hol...@fam-schranz.de>wrote: > Ups, sorry for my wrong answer :( ... > > Best regards > > Holger > > Am 03.06.2013 17:06, schrieb Maxim Solodovnik: > > JDK7 works as expected also > you need to inspect openmeetings.log to find the root cause > > > On Mon, Jun 3, 2013 at 9:31 PM, Holger Schranz <hol...@fam-schranz.de>wrote: > >> Hello Manoel, >> >> OM 2.1 require JRE 1.6. >> >> Best regards >> >> Holger >> >> Am 03.06.2013 16:28, schrieb Manoel Campos da Silva Filho: >> >> 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 >> >> org.apache.velocity.tools.view.VelocityView.performMerge(VelocityView.java:942) >> org.apache.velocity.tools.view.VelocityView.merge(VelocityView.java:902) >> >> org.apache.velocity.tools.view.VelocityViewServlet.mergeTemplate(VelocityViewServlet.java:318) >> >> org.apache.velocity.tools.view.VelocityViewServlet.doRequest(VelocityViewServlet.java:220) >> >> org.apache.velocity.tools.view.VelocityViewServlet.doGet(VelocityViewServlet.java:182) >> javax.servlet.http.HttpServlet.service(HttpServlet.java:621) >> javax.servlet.http.HttpServlet.service(HttpServlet.java:728) >> >> org.red5.logging.LoggerContextFilter.doFilter(LoggerContextFilter.java:77) >> note The full stack trace of the root cause is available in the Apache >> Tomcat/7.0.34 logs. >> >> >> > > > -- > WBR > Maxim aka solomax > > >
