the error: "org.neo4j.graphdb.NotInTransactionException"

The error message is somehing like this:

The solution is using transactions explicitly..
http://stackoverflow.com/questions/11485090/org-neo4j-graphdb-notintransactionexception

@Autowired
private GraphDatabaseService graphDb;

@Transactional
public void addRelation() {
  Transaction tx = graphDb.beginTx();
  ...
  tx.success(); //or tx.failure();
  tx.finish();
}

the error:"Referenced file contains errors (http://www.springframework.org/schema/beans/spring-beans-4.0.xsd)"

The error message is:

Referenced file contains errors (http://www.springframework.org/schema/beans/spring-beans-4.0.xsd).

In summary, the error may be resolved by doing the following:
" It was caused by some cached files. After removing those items (Preferences -> General -> Network Connections -> Cache) everything worked as expected. "
However, in my condition it was not helpful :( Another cause is using different versions together as stated:
"This error may have appeared because you had a mix of 2.5 xsd and 3.0 xsd in your applicationContext.xml. "
When i removed the version info from every element in xsi:schemaLocation, the project compiled successfully..

telerik:GridTemplateColumn problem after migrating from Visual Studio 2012 to 2013

After migrating my project from Visual Studio 2012 to 2013, i realized that telerik grids with GridTemplateColumn columns did not render successfully. The solution is adding the following to Web.xml:

dependency injection in .net - ninject

i am spending this cold but bright sunday at home, since my mother had a simple surgery-like operation lately. So i am trying to solve some problems today to facilitate my week. One of those is refactoring my C# project by applying dependency injection.

Here is a short video which clearly explains the concept: http://www.youtube.com/watch?v=IKD2-MAkXyQ

My tool choice is ninject, since it is lightweight and does not require to write an xml for configuration. ( Despite being a SOA developer for several years in the past and dealt with bpel for a while, i still do not like using XML as a programming language. Here is an up-to-date discussion about it: http://programmers.stackexchange.com/questions/213316/xml-based-programming-languages )

And it is the Guice equivalent of .net :)) http://stackoverflow.com/questions/10844787/guice-equivalent-in-c-sharp

Here is Ninject home page: http://www.ninject.org/
