feedreader | Go package for parsing RSS

Correct version of your code

A web application is fundamentally unsuited for this type of task. A website's job is to respond to requests from others (usually people, via browsers) as and when they occur. It does not run automatically at specific times.

To achieve your goal, on your server you need either a Windows Service with a timer in it (which then executes the necessary code every time the timer expires), or a Windows Scheduled Task which triggers a specific application at regular intervals.

Since you already have a Console application which does the job you need, then the simplest solution for you is probably to set up a Windows Scheduled Task which executes the console application regularly.

N.B. You can of course still have a separate website which can display the data that the console application has saved in the database.

P.S. There are extensions to ASP.NET such as Hangifire and Quartz.NET which can add scheduling capabilities to a web application, but they are probably overkill for what you want to do in this case.

In the table there are 4 columns and the primary key.
When you insert a new row you supply values for the ContentValues object but you do it twice for each column:

This bug is caused by the Mylyn Bugzilla connector using classes of the javax.xml.bind package that has been introduced in Java 6, but removed in Java 11 (see: JEP 320: Remove the Java EE and CORBA Modules).

In Eclipse, the Bugzilla connector is used for the following features that are broken when the mentioned error is logged each time Eclipse is started:

• Help > Report Bug or Enhancement...
• Search > Search..., tab Task Search

Unfortunately, this bug still exists in Eclipse 2018-12 in some of the IDE packages, including the Eclipse IDE for Java Developers you use (in your log as -product org.eclipse.epp.package.java.product).

Use one of the following as a workaround (tested with Eclipse 2018-12):

• Use Java 8, 9 or 10 to run Eclipse, but in Window > Preferences: Java > Installed JREs use a Java 11 JDK
• Use the Eclipse IDE for Enterprise Java Developers instead of the Eclipse IDE for Java Developers
• Copy the following JARs from Eclipse Orbit into the dropins folder of your Eclipse 2018-12 IDE:
  • javax.xml.bind 2.2.0
  • javax.activation 1.1.0
  • javax.xml 1.3

For details see my (for 2018-12 unfortunately too late) mails on the Eclipse cross-project-issues-dev mailing list here and here.

The static local variables are likely throwing off your processing. Remember that a static local variable persists its value between function invocations. Once streamFile() exits, and is then called again, your static variables will still have their previous values, they will not be reset back to their original values. You would have to change them to be members of your CXMLManager class instead so that streamFile() can reset them each time it is called.

I don't suggest using a single function to try to handle every possible node you need to parse. I would break up the reading into separate functions that have their own responsibilities at each level of the XML document, something like this:

80 is the default HTTP port. 443 is the default HTTPS port.

Downgrading Primefaces to 5.3 version (from 6.*) and including jdom-1.1.1.jar library seem to have solved the problem. Primefaces RSS reader is working now. Can't really say if it's Primefaces version problem, or jdom dependency, or both. Just hope this would at least give a clue to someone who might come up with the same issue.

Thanks for help, guys!

Nothing happens because an exception is thrown as you are trying to modify UI element outside of UI thread. You should either use textBlock.Dispatcher.Invoke method or make FeedReader asynchronous and use async/await in your method, which is preferable.

So the prefered solution would be (provided RetrieveFeed is async method):

Add 'NbBundle' to your imports:
