Hi to all,

I’m new to Gatling and a pure noob in Scala.

I’ve this code :

def apply = {

val extUsers = Integer.getInteger(“users”, 1)

val extRampup = Integer.getInteger(“rampup”, 0)

val extPause = Long.getLong(“pause”, 1L)

…

val chain\_0 = chain

.exec(

http(“request\_1”)

.get(extWebapp + “/libs-release/com/me/parent/parent/3/parent-3.pom”)

.headers(headers\_1)

)

.exec(

http(“request\_2”)

.get(extWebapp + “/libs-release/com/me/parent/parent/3/parent-3.pom.sha1”)

.headers(headers\_1)

)

.pause(extPause, MILLISECONDS)

.exec(

http(“request\_3”)

.get(extWebapp + “/libs-release/com/me//web/1.0.0-12/web-1.0.0-12.pom”)

.headers(headers\_1)

)

.pause(extPause, MILLISECONDS)

pause require Long but I wonder how to get Long from parms ?

Error was :

```auto
Collecting simulations...
Exception in thread "main" java.lang.RuntimeException: Compilation failed:
simulations/com/me/Clean.scala:13: error: value getLong is not a member of object Long
               val extPause = Long.getLong("pause", 1L)
                                    ^
simulations/com/me/Clean.scala:13: error: value getLong is not a member of object Long
        val extPause = Long.getLong("pause", 1L)

```

Thanks for your help 🙂

val extPause = System.getProperty(“pause”).toLong if you want to be able to pass a number \> Integer.MAX\_VALUE

or val extPause = Integer.getInteger(“pause”, 1).toLong if you want a default value

Cheers,

Actually, I wonder if Duration might be Integers instead of Longs.

Thanks, I used this.

Now, I should refactor generated .scala, got class too large error at  
compile time ;-/

Really? Wow

What’s your stacktrace? You can maybe edit the JVM options so it can compile.

I collected a maven build with about 1250 HTTP requests 🙂

Ouch!

Well, you could probably refactor your Simulation (for example, build file and sha1 requests together), but I’m not sure it would help from a maintenance standpoint.

You can probably tweak some JVM options so Gatling can compile your Simualtion.  
What’s your stacktrace exactly?

I didn't keep it but it was a message about Class of 96kb tool large error

I wasn’t aware of this kind of limit.  
Feel free to send it to me so I can have a look.

OK,

So you can do something very simple: move all your chains definitions out of the method.

You have something like:

class MySimulation extends Simulation {

def apply = {  
val chain1 = …  
val chain2 = …

val scn = scenario("foo)  
.insertChain(chain1)  
.insertChain(chain2)  
…

List(scn…)  
}  
}

Transform it into:

class MySimulation extends Simulation {

**lazy val chain1 = …**  
**lazy val chain2 = …**

def apply = {  
val scn = scenario("foo)  
.insertChain(chain1)  
.insertChain(chain2)  
…

List(scn…)  
}  
}

and you should be fine

Tremendous.

That's what I call a strong and reactive support.

Thanks Stéphane !

You’re welcome.

That was a funny one, I’ll add it to the FAQ.
