I can't run any application with WebRatio (Table/View 'APP.POST' does not exist)

Hi! I'm having a big problem: I can't run any application with WebRatio. I installed in a Ubuntu x64 system following this guide: http://www.webratio.com/learn/article/WebRatio-Installation-Guide

Everything works fine: WebRatio starts, Tomcat is working (I checked http://localhost:8080/). But the problem is every time I press the "generate and run" button, my browser opens and throw me this error:


An error occurred

Table/View 'APP.POST' does not exist.

Occurred on:

  • pwu1 [PowerIndexUnitService]


  • [pwu1] org.hibernate.exception.SQLGrammarException: could not execute query using iterate

  • could not execute query using iterate

  • Table/View 'APP.POST' does not exist.


  • Refresh the database(s) and run the 'Find Model Problems' command on the domain model

  • Check the database Runtime properties (if defined)

  • Run the 'Generate Selection' command on the accessed page/operation


And the only component my site view has is one homepage with a list of existent posts.

I think maybe the problem is when I set up Tomcat, because ./startup.sh shows this message:

Using CATALINA_BASE:   /opt/WebRatio_Personal_7.2.x64bit.Linux/Tomcat
Using CATALINA_HOME:   /opt/WebRatio_Personal_7.2.x64bit.Linux/Tomcat
Using CATALINA_TMPDIR: /opt/WebRatio_Personal_7.2.x64bit.Linux/Tomcat/temp
Using JRE_HOME:        /usr
Using CLASSPATH:       /opt/WebRatio_Personal_7.2.x64bit.Linux/Tomcat/bin/bootstrap.jar
So I add the next line to the top of catalina.sh:
I relaunch the ./startup.sh:
Using CATALINA_BASE:   /opt/WebRatio_Personal_7.2.x64bit.Linux/Tomcat
Using CATALINA_HOME:   /opt/WebRatio_Personal_7.2.x64bit.Linux/Tomcat
Using CATALINA_TMPDIR: /opt/WebRatio_Personal_7.2.x64bit.Linux/Tomcat/temp
Using JRE_HOME:        /usr/lib/jvm/java-7-openjdk-amd64/bin
Using CLASSPATH:       /opt/WebRatio_Personal_7.2.x64bit.Linux/Tomcat/bin/bootstrap.jar
But when I press the "generate and run" button, I get the same previous error (Table/View 'APP.POST' does not exist.). So, how can I found the database in order to check if it really exists?? How can I solve this??
Extra info: I did a simple ER model and I syncronized it, so it should exist.

Verify that you have installed Apache derby on your application server, or configure an additional database like mysql or postgres, http://dev.mysql.com/downloads/mysql/, http://www.postgresql.org/.

Refresh the database(s) and run the 'Find Model Problems' command on the domain model whit a new database

Thanks Luis! I refreshed and do the "find model problems" but there was no errors. I know the database is working because I can establish a demo connection when I created the project. The problem is how can I access the Apache derby databases from my application server? I want to execute some SQL statements in order to see if tables do exist.
