Professor I tried what you said, and also tried many other things. Reinstalled all the plugins carefully and the problem still persists.. I'm clueless at the moment.
1) I checked out the csns2 repository perfectly. 2) Right click project - > new file ->build.properties 3) copied the content in build.properties.sample to the source of build.properties 4) Right-clicked csns2 -> maven -> update project configuration 5) right clicked csns2 -> run as ->run on server -> tomcat is located in my e:/ drive 6) Programs runs and gives me the same exception. nested exception is javax.persistence.PersistenceException: org.hibernate.exception.GenericJDBCException: Cannot open connection org.apache.commons.dbcp.SQLNestedException: Cannot create JDBC driver of class '' for connect URL 'jdbc:postgresql://localhost:5432/csns2' java.sql.SQLException: No suitable driver

It says it could not load the database driver. This could happen if Maven got interrupted when it tried to download the database driver. So go to the home directory of the user (e.g. on Windows Vista it's C:\Users\<username>), then delete the postgresql folder under .m2/repository. In Eclipse, right click the project then select Maven -> Update Dependencies. Wait until Maven finishes downloading the library (you can see it in the Progress view), then try running the project again. |

I am a little confused , I have setup tomcat 7 in eclipse , and if I were to create a dynamic web project like 320 course , then I have the option to run on server which is tomcat , but when I right click on csns2 project and go to "run as " option then I do have many other options like "4 maven build" , "5 maven build" and ... but there is no option to run on server and when I go to run configuration of this specific project then the drop down list under tomcat has nothing and there is a small red error cross next to it .

You probably didn't install m2e-wtp. Last edited by cysun at

Error is still there.
I added a dependency manually, still didn't work. Giving me same errors. The postgres jar exists in the postgres folder and in pom.xml. I updated project configuration also. |

So I went to sleep at 3:30 AM. 2 minutes into sleep, something in my head said, "Tomcat isn't cooperating". Went to eclipse, change the tomcat server from 7.0.21 to 7.0.11, and voila the problem was gone. I also changed from jdk6 to jdk7. I doubt it was the jdk though. Aligh1979, try using Tomcat 7.0.11 instead of the latest version of tomcat7 which is 7.0.21. Thanks Dr. Sun for helping me out. |

You may not need to downgrade Tomcat. It's possible that the corrupted jar file got "stuck" in the Eclipse work directory. Try cleaning the work directory first. Last edited by cysun at
