hi Thierry Im really sorry for the partial information in the post. i will just explain what i have done till now so it more clear about my problem.
In matlab we can add the jar files dynamically or statically. Adding Jar files to matlab math dynamically ============================== I tried to add the following jar files org.restlet.ext.json-1.1.7.jar org.json_2.0.0.jar org.restlet-1.1.7.jar com.noelios.restlet-1.1.7.jar dynamically (using matlab command javaaddpath). The jar files currently inside the matlab environment can been seen with command javaclasspath. Now i was able to see all the jar files mentioned above in the javaclasspath. Then when i tried to create a client Client(Protocol.HTTP) I got the following error ??? Java exception occurred: java.lang.RuntimeException: Unable to fully initialize the Restlet. No Restlet engine available. But this problem was solved when i added the jar files statically to matlab. (We can do that by editing the classpath.txt). (I dont know the reson for this because im not sure how the classloading for matlab works.I got the info from the forums that there has been difference in behaviour between static and dynamic class loading). After this problem was solved When i tried to execute to Client(Protocol.HTTP) i got the warning No available client connector supports the required protocols: 'PROTOCOL.HTTP Protocol' . Please add the JAR of a matching connector to your classpath. But based on your inputs i tried to include following jar files also to matlab class path i.com.noelios.restlet.ext.net.jar and also i tired adding org.apache.commons.httpclient.jar and com.noelios.restlet.ext.httpclient_3.1.jar These were done as separate trials. Still i have the same warning. Can u pls let me know what all information you need from matlab side so that we can figure out this issue.
