I am having a class build for sending emails. But I am recieving the below exception when I am starting my class.

This is a maven project and the dependency I have used is :

<dependency>
	<groupId>javax.mail</groupId>
	<artifactId>mail</artifactId>
	<version>1.4.7</version>
</dependency>

I even verified the jars, mail-1.4.7.jar, activation-1.1.jar both the jars are present at classpath.
Anyone have any clue why I am receiving this excetion?

[Dana Ucaed]

Probably it is missing another jar file.

[Puspender Tanwar]

but which jar file? Maven installs all the dependencies.

[Dana Ucaed]

I recomand to download the jar file and attach to the project.

Maybe be a problem with your local repositories.

Or you can close your project and reopen again.

[Puspender Tanwar]

tried both. but no luck.

[Daniel Demesmaecker]

you also have to add the javaEE dependencie:

 <dependency>
            <groupId>javax.el</groupId>
            <artifactId>javax.el-api</artifactId>
            <version>3.0.0</version>
        </dependency>

[Rob Spoor]

I've never needed EL to use JavaMail.

[Daniel Demesmaecker]

I refer to my post from two weeks ago.
Adding the mentioned dependency solved my problem...

Added. Updated the project, but still same issue :  Exception in thread "main" java.lang.NoClassDefFoundError: javax/mail/Transport
I even verified for the javax.mail.Transport class in mail.jar, and it's present.

[Daniel Demesmaecker]

I don't know why you have two different sets of propperties or what's in "SPSAdapterProp.properties"
I tried to inport your code, but because I dont have the above mentioned proppertyfile, it dosn't work.
Anyway if the same code works on someone elses computer it has to be a dependency issue.
You manually added all the jars? Have you cleaned your project after?

[Puspender Tanwar]

I tried running your code as well, but the same issue.
For your code, I manually added the mail.jar and activation.jar on the classpath.
This is very strange, why only on my system the code is not working.

[Daniel Demesmaecker]

When trying to run my code did you add the javaee-api dependency?
It has to be a dependency issue. Can I see your pom?

[Daniel Demesmaecker]

By the way from java6 on, you don't need the activation.jar

[Puspender Tanwar]

Yes it's by default under jdk.

Try to displace the javax.mail and the javax-el dependencies with

      <artifactId>javax.mail</artifactId>
      <version>1.6.0</version>

[Dana Ucaed]

You must add the jar file as dependencies, not in classpath.

What editor did you use?

That has the same result, if you add the dependencies, maven automaticly downloads them and put them on your classpath...
It makes no difference if you download them and put them in your classpath or let maven do it

Still same issue. I am using eclipse. I am guessing something is wrong with my system or java. I will try to execute the same code on my other system.

[Dana Ucaed]

Please create another project without MAVEN and add the dependencies manual.

MAVEN created me the problems.

[Rob Spoor]

Daniel Demesmaecker wrote:if you add the dependencies, maven automaticly downloads them and put them on your classpath...

But only for compiling, not for running applications (unless you do that through Maven).

That leaves a question for Puspender Tanwar: how do you start your program? Did you add the dependencies to the class path?

I am running the program from Eclipse itsef. All other dependencies are working properly.

Already tried. No change in error.

[Daniel Demesmaecker]

Did you try running it on your other system?
could you post the SPSAdapterProp.properties, then I wil try to rebuild it on my computer

[Puspender Tanwar]

It's running fine on my other system. Attaching the properties file. But it's very weird why it is failing on my this system.

Does this mean that you have two systems where you're using Maven to generate something and then using Eclipse to run that something?

[Puspender Tanwar]

Paul Clapham wrote:Does this mean that you have two systems where you're using Maven to generate something and then using Eclipse to run that something?

Yes exactly. And that something is behaving differently on both the systems. I am checking in and checking out the code from SVN. So no chance of code being different.
