PostHeaderIcon org.springframework.beans.factory.xml.XmlBeanDefinitionReader: Ignored XML validation warning org.xml.sax.SAXParseException: SchemaLocation: schemaLocation value = … must have even number of URI’s

Context

Mule 2.2.1 ESB config file with a TibcoRV connector, under Windows XP SP2 and Java 5.
The error happened in this context, yet I assume it would occur in any occurence related to XSD / XML schemas.

Error

org.springframework.beans.factory.xml.XmlBeanDefinitionReader: Ignored XML validation warning

Explanation – Fix

Each time, the attribute xsi:schemaLocation must have an even number of lines: a “public” XSD address and a “non-public” one. For non English-fluent speakers, I remind that a number is even if, and only if, it is a multiple of 2 ; otherwise it is odd.

In our case, one line is redundant. To fix this issue, you have to remove the redundant line, and ensure each line belongs to a consistent pair of lines: for instance:

http://www.mulesource.org/schema/mule/tibcorv/2.2
and
http://www.mulesource.org/schema/mule/tibcorv/2.2/mule-tibcorv.xsd

PostHeaderIcon Tibco RendezVous quick-start tutorial

When I was introduced to TIBCO Rendezvous (also spelled “Tibco Rendez-Vous” or, shorterly, “TiboRV”), I faced a embarrassing issue: the lack of documentation and tutorials on the web.

The purpose of this -short- tutorial is to guide you until you can send and read a “HelloWorld” message passing through Tibco RendezVous

Installation

  • Set the variable JAVA_HOME
    Eg, in my case:

    set JAVA_HOME=C:\exe\java\jdk150_10
  • Get the file to be installed:
    TIB_rv_8.1.2_win_x86_vc8.zip
  • Unzip the content in your local drive
  • Launch the installer (.exe)
    • select Custom installation
    • choose the installation folder, eg: C:\exe\tibco
    • keep default options for other requests
  • Set the variable TIBRV_HOME
    Eg, in my case:

    set TIBRV_HOME=C:\exe\tibco\tibrv\8.1

Main Runnables

RVD: Daemon

  • Launching the daemon on local host on port 8181 (default port: 7580):
    rvd -http 8181

    You should see the following trace:

    C:\exe\tibco\tibrv\8.1\bin>rvd -http 8181

tibrvsend: send a message

To send a message on myLocalMachine:7580:

.\tibrvsend.exe -service 7580 -network MYLOCALMACHINE mySubject myMessage

Expected output:

C:\exe\tibco\tibrv\8.1\bin>.\tibrvsend.exe -service 7580 -network MYLOCALMACHINE mySubject myMessage
Publishing: subject=mySubject "myMessage"
2010-01-19 16:52:11 RV: TIB/Rendezvous Error Not Handled by Process:
{ADV_CLASS="WARN" ADV_SOURCE="SYSTEM" ADV_NAME="LICENSE.EXPIRE" ADV_DESC="The license will expire" expiretime=2010-01-19 16:02:11Z host="10.30.226.147"}

tibrvlisten: listen to messages

Abstract

To listed to messages published on MYLOCALMACHINE:7580, related to subject mySubject:

tibrvlisten -service 7580 -network MYLOCALMACHINE mySubject

Use case: HelloWorld

For instance, let’s assume that you launch this command from one frame:

C:\exe\tibco\tibrv\8.1\bin>.\tibrvsend.exe -service 7580 -network localhost mySubject HelloWorld
Publishing: subject=mySubject "HelloWorld"

Here is what appears in the “listening” frame:

2010-01-19 17:01:32 (2010-01-19 16:01:32.990000000Z): subject=mySubject, message={DATA="HelloWorld"}

Notice you can have many instances listening to the same messages.

Other runnables

Launch the daemon manager

  • Launch:
    cd %TIBRV_HOME%/RVDM
    ./RVDM.bat -http 8282 .
  • You should see following messages, that you can ignore:
    2010-01-19 13:01:48 rvdm: RVDM has activated.
    2010-01-19 13:02:03 RV: TIB/Rendezvous Error Not Handled by Process:

    xpiretime=2010-01-19 12:11:48Z host="123.123.123.123"}
  • To check the daemon is on, you can open the address http://localhost:8282 on your favorite browser.

Example sources are available in folder %TIBRV_HOME%/src/examples/java
