Case

In a JUnit test, I send a message on a TibcoRV, but I get the following error:

TibrvException[error=4,message=Tibrv not initialized]

Fix

In order, proceed as this:

1. check an RVD daemon is running 😉
2. check tibrvj.jar is in your classpath 😉
3. check the instanciation of transport layer new TibrvRvdTransport(service, network, daemon); is done within your public void testXXX(), and not in the setUp().

Here is a short comparative of webbrowsers available on Windows Mobile 6.1. I used them on a Acer X960 on French VirginMobile network.

As a conclusion, what do I do?

• In most cases, I use Opera, for its speedness and tabs.
• When I need watch a video
  • my Acer X960 displays YouTube videos in a specific player
  • on other websites, I use SkyFire.
• For Google applications (GMail, Reader, Docs, etc.), I use SkyFire, too.

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.

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

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"

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:
  {ADV_CLASS="WARN" ADV_SOURCE="SYSTEM" ADV_NAME="LICENSE.EXPIRE" ADV_DESC="The license will expire" e
  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

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

Misc

TIBRV_HOME\bin folder fosters a couple of binaries:

• rvntscfg.exe: Services Configuration Program

Case:

Under Windows / Tomcat 6:

[java]java.lang.SecurityException: Servlet of class org.apache.catalina.servlets.CGIServlet is privileged and cannot be loaded by this web application[/java]

Fix:

In the web.xml file, add the following block:

[xml]
<context-param>
<param-name>privileged</param-name>
<param-value>true</param-value>
</context-param>[/xml]

Case:

We need use JAXB2 packaged version, rather than the version which is provided within WebLogic 9.2.

Fix:

In the weblogic-application.xml, add the following block:

[xml]
<prefer-application-packages>
<package-name>javax.xml.bind.*</package-name>
</prefer-application-packages>
[/xml]

Case:

I use Zone Alarm as firewall on my Windows XP SP2. When the system boots, it displays a window with the message:
Validation failed for C:\windows\SYSTEM32\vsinit.dll you probably are missing a necessery root certificate
The file is present on my disk.

Fix:

• Disconnect from internet 😉
• Close Zone Alarm
• Uninstall Zone Alarm
• Reboot
• Rename C:\windows\SYSTEM32\vsinit.dll as vsinit.dll.old (or delete it)
• Install Zone Alarm
• Reboot

It should be OK 😉

Le mardi 15 decembre 2009 j’ai anime une nouvelle presentation “La Methodologie Scrum”. A cette occasion, j’ai ameliore le support powerpoint pour prendre en compte certaines remarques qui m’avaient ete faites.
La presentation est disponible, sous licence Creative Commons CC-by-cc, est heberge sur GoogleDocs.

Yeah, I know this must be widely known, yet I needed a short while before successing ;-).
Case: I must mount a Java projet from a Maven2 file, under Eclipse (I am back to my prefered IDE).

Fix:

• Checkout the sources from version control tool
• Open a console window
• Go to the project home
• (possibly: mvn install)
• mvn eclipse:eclipse
• Open Eclipse
• File > New Project > add the name > check "create project from existing tool" > Finish

And it’s over!
