Error in webapp - javax/xml/soap/Detail violates loader constraints

added this to my pom.xml

<dependency>
<groupId>javax.xml.soap</groupId>
<artifactId>saaj-api</artifactId>
<version>1.3</version>
</dependency>

because i could not get the SOAPFaultException.Detail value

and got this when exception was being handled

because I should have set dependency scope to "provided"

<dependency>
<groupId>javax.xml.soap</groupId>
<artifactId>saaj-api</artifactId>
<version>1.3</version>
<scope>provided</scope>
</dependency>
