Latest Driver for tjdbc not working - Talend - mysql

Hi I'm using Talend Open Studio , version 6.5.1
I'm using tjdbc components. I changed the driver from mysql-connector-java-5.1.30-bin.jar to mysql-connector-java-5.1.45
This change does not allow me to connect to mysql and returns the following error when I run the job.
May I know what changes must I do to get this working.

It was the issue of not setting auto commit = false in the jdbc component. It worked now. Apologies for the confusion

JMeter: After installing Blazemeter plugin for Random CSV, Jmeter is not allowing to right click on "Test Plan"

I just installed bzm plugin for Random CSV but now Jmeter is not allowing to right click on "Test Plan".
Even, "edit" menu looks diabled, have restrated JMeter multile times, still no solution. Please help. Also, this is not the first time I have faced this issue after adding and installing plugins.
Below are errors in log:

Spring-data-neo4j-Neoclipse-Lucene corrupt index Exception

I have configured my application using Spring-data-neo4j, where I can successfully persist, create relationships, etc.
Once I persist the data and stop my application, I then want to visualize the graph that I've created in NEOCLIPSE.
I can successfully see the graph as well in NEOCLIPSE.
The only problem I am having is.. once I close the connection in Neoclipse, and then re-run my application to listAllSavedEntities on a web page, I get this error :
`SEVERE: Servlet.service() for servlet [spring] in context with path [/sample] threw exception [Request processing failed; nested exception is java.lang.RuntimeException: org.apache.lucene.index.CorruptIndexException: unrecognized format -3 in file "_0.fnm"] with root cause

I simply closed the connection in Neoclipse and then tried to list out my persisted entities. Nothing more to that.
I am not sure what's wrong in here :( :(
Any help would be appreciated.
Thanks.
What neo4j kernel version does your neoclipse use and which one your application? Could it be that there is a version mismatch? Maybe neoclipse upgrades the data directories content to a newer version under the hood. That could be the cause for that unrecognized format -3 error message in your application.

I'm using Oracle Forms 10 release 2 and I'm running it in Windows XP Mode.
After much headache I did found out that this is caused by incompatibility between Oracle Forms 10 release 2 (10.1.2.0.2) and Java 6. The error occur when using the list item as a combo box. Fortunately there is a fix and that are to apply Oracle Developer Suite 10g Release 2 (10.1.2) Patch Set 3 (10.1.2.3.0) on the local Oracle Home. Unfortunately this is not listed on the forms download site and therefore easy to miss.

I have included all my classes plus all externan jar files in one .jar and i use it when i call the applet from the HTML.
My HTML is as simple as it gets:
<html>
<title> Performance App </title>
<body>
<h2> Applet... </h2>
<applet code=lefty.AppletSetup.class width="200" height="200" archive="performanceApp.jar">
</applet>
</body>
</htmL>
Also i have to mention that one of my class extends RunListener but I have included the junit.jar in my classpath and final jar.

Some points as
A) How did you included external jars to your project jar?
B) classpath - you mean a util running?
C)
Caused by: java.lang.ClassNotFoundException:
org.junit.runner.notification.RunListener this line says the class is really missing so is it in project jar ?
And I suppose you shouldn't deploy applet with unit test code; Just because all unit tests are for IDE applet emulating running; So try to deploy it without junit
Good luck
