Hi,

you need to add the CDO provider to your run configuration.

Best regards

Hi,

have you validated somehow, that the CDO repository is there and the
repository is running on this port?

Best regards

Jonas

I have tried to run the sample CDO client example and it runs properly with the same repository credentials but when i try ECP demo then i get the above shown exception....

I am running the MasterServer example for CDO
<acceptor type="tcp" listenAddr="0.0.0.0" port="2036"/>
<repository name="repo1">
<property name="overrideUUID" value=""/>
<property name="supportingAudits" value="true"/>
<property name="supportingBranches" value="true"/>
<property name="ensureReferentialIntegrity" value="false"/>
<property name="allowInterruptRunningQueries" value="true"/>
<property name="idGenerationLocation" value="CLIENT"/> <!-- Possible values: STORE | CLIENT -->
<property name="serializeCommits" value="false"/>
<property name="optimisticLockingTimeout" value="10000"/>


Please check the image for adding repository dialog in ECP

connctory type: tcp
host : localhost
port: 2036
name : repo1

Do you have any idea about my problem?

That "null" at the end probably means that the CDO client (here: ECP/CDO Provider) has not sent the correct repository
name ("repo1")to the server.

I don't have the ECP sources at hand (nor do I have the time right now), but if you want to debug it, I would start by
setting a breakpoint on the client in the constructor of OpenSessionRequest.java and find out why the passed repository
name is null.

Cheers
