Senthil,

Welcome to JavaRanch

Your post would be more appropriate in our EJB Forum. Maybe the moderator will move it there for you.

Senthil, could you please explain more about this warning? When do you see this? Is there any other exception stacktrace that you see?

jaikiran,
Actually i try to implement EJB in GWT-RPC.I got this error,
other than this error,nothing i faced.

Warning: The Bean Provider must specify the fully-qualified name of the Java class that implements the enterprise bean's business methods in the <ejb-class> element.

Senthil,

Please post the entire exception stacktrace that you are seeing. Also, please repost the contents of your ejb-jar.xml, and this time please use the Code button to wrap the contents neatly in a code block. That way its make easier to read the contents.

Also, how is the application deployed? Is it an archive or an exploded folder? If its an archive then post the output of the following command run from the command prompt:

jar -tf myApp.ear

where myApp.ear is the application archive

[senthil baskaran]

This is my EJB-JAR.xml

<ejb-jar>

<enterprise-beans>

<session>

<ejb-name>CheckPriceEJB</ejb-name>

<home>CheckPriceHome</home>

<remote>CheckPrice</remote>

<ejb-class>CheckPriceBean</ejb-class>

<session-type>Stateless</session-type>

<transaction-type>Container</transaction-type>

</session>

</enterprise-beans>

</ejb-jar>

i am using java archive(jar)to deploy the application.

(Unsupported major.minor version 49.0)

Looks like you are compiling your classes using Java 5 version and deploying on JBoss, using an earlier version of Java (maybe Java 1.4). Make sure you compile using Java 1.4 or configure the JAVA_HOME for JBoss to use Java 5, so that the correct Java version is used for deploying your beans.

[senthil baskaran]

thanks for your suggestion,the problem get solved.module is deployed

successfully.But,i am facing another problem in the same application i.e

i cant render my page in the browser after deployed successfully.i am

Many Thanks Jakiran, your suggestion worked beautifully.

Although my Eclipse prefs is set to use Java 1.4 (nothing specific for project) and Prefs -> Java -> 'compiler compliance' is also set to 1.4, and ant compiles using 1.4 (ant.java.version), and JBoss runs using 1.4, yet it still kept giving the error: -

WARN [verifier] EJB spec violation:
Section: 22.2

Info : Class not found on xxx: Unexpected error during load of: xxx, msg=xxx (Unsupported major.minor version 50.0)


Nevertheless, changed JBoss launch config to use JRE 1.6 and it worked!
