Cannot install sample apps manually

[ Edited ]



I'm having a hard time installing Push SDK sample apps in a remote machine. I'm trying a manual installation of Tomcat. The machine runs Linux Red Hat.


The error I get is:



[org.springframework.web.context.ContextLoader.initWebApplicationContext()] - Context initialization failed
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'registerListeners' defined in class path resource [sample-push-initiator-context.xml]: Invocation of init method failed; nested exception is org.springframework.transaction.CannotCreateTransactionException: Could not open JDBC Connection for transaction; nested exception is org.apache.commons.dbcp.SQLNestedException: Cannot create PoolableConnectionFactory (Communications link failure

The last packet sent successfully to the server was 0 milliseconds ago. The driver has not received any packets from the server.)

 It looks like a problem with the JDBC connector, but I don't know how to solve it. Among the things I've already done are:


  • Generate the database manually.
  • Fill out PushSDK.properties with the database and JDBC info. Copy this file in each of the sample apps WEB-INF/classes directory
  • Copy mysql connector jar file into each application's WEB-INF/lib directory
  • Edit app.properties file with my BB credentials (app id, PGG base url etc). Copied it into the apps WEB-INF/classes directory. I did the same with acknoledgement-context.xml and app-context.xml
  • Edit Tomcat's conf/server.xml to set the ports for http and https and UTF-8 encoding for the query component of the request URL. Actually, I only have port 8080 available in the machine and I've configured HTTPS to work there. 
  • Issue a self-signed certificate and indicated its location in conf/server.xml file. Indicated it's location in conf/server.xml
  • Edit bin/catalina.sh to set UTF-8 encoding in JAVA_OPTS



Tomcat's initial page seem to be working fine in https://machine_ip:8080/

But there are errors with the BB apps:



  • https://machine_ip:8080/sample-push-initiator returns 404
  • https://machine_ip:8080/pushsdk returns 404
  • https://machine_ip:8080/debug-portal does open the Debug Portal, but shows the following message:
Internal Server Error: 

Sorry, we are unable to properly process your request at this time. Please contact a system administrator to investigate the problem by examining the logs.


Does anyone have any idea of what is going on? I would greatly appretiate some help


Best regards,

Re: Cannot install sample apps manually

Hi all!


I could finally solve this problem. MySQL was not allowing the connection from JDBC. I've

had to remove the line:





in MySQL configuration file ( /etc/my.cnf ) and now the sample apps seem to be working ok.

I still cannot subscribe the client though, but that's a different story...
