Hi Samba,

It looks like you put a path to the studio which contains a space and you didn't quote the path.

Concretely you should probably try

mvn package talend-component:deploy-in-studio -Dtalend.component.studioHome="C:/Program Files/Studio"

You can check the logs in workspace/.metadata/.log (if there is any error).

You can also connect on your studio through JMX (jvisualvm/jconsole/jmc would do the trick) and check it is registered in talend MBeans.

Any error earlier in the log file? It looks like the studio can't access the local components server.

Did you tweak your config.ini to use the global repository (this would require you to ensure you have the component-server in your dependencies)?
Do you have a firewall preventing some localhost communication (MacAfee does it sometimes)?
Do you have multiple network cards?

Hi, @rmannibucau, yes i tweak my config.ini file with

maven.repository=global and the dependencies in my pom.xml file looks like this

<dependency>
      <groupId>org.talend.sdk.component</groupId>
      <artifactId>component-server</artifactId>
      <version>1.0.4</version>
        <scope>
        provided
    </scope>
    </dependency>
    <dependency>
      <groupId>org.talend.sdk.component</groupId>
      <artifactId>component-api</artifactId>
      <version>1.0.2</version>
      <scope>provided</scope>
    </dependency>

But still i get this error java.lang.IllegalStateException: javax.websocket.DeploymentException: The HTTP request to initiate the WebSocket connection failed

should in case i m behind a proxy, is there any configuration that can fix it?

thanks in advance

Hi Samba,

You should not have component-server in your pom (if it is due to anything unclear in the doc, feel free to mention it, we'll try to clarify it). The starter normally does all the setup for you.

However, it guarantees you have the server 1.0.4 in your local repository but the studio integrated version is likely not this one (which was released only yesterday) so it likely doesn't achieve your original goal.

In terms of proxy, there is no need of any remote communication (it is all local) so you should ensure the proxy does not proxy localhost.

To test the server you can set in your configuration/config.init the property:

component.java.port = 8080
component.environment = dev
component.server.jul.forceConsole = true
java.util.logging.SimpleFormatter.format = [%4$s] %5$s%6$s%n

It will force the component server to start on localhost:8080 (you can use any port you want) and to log the server output in the console (launch the studio from a terminal). This will allow us to see if there is any issue during the startup. If not you can also check the server is started calling http://localhost:8080/api/v1/environment which should return you a JSON payload with some information about the server.

Hi @rmannibucau,

Thank you, problem solved, just one more question please, in which folder are the newly generated components installed, with the Talend 6 it used to be \plugins\org.talend.designer.components.localprovider_x.x.x.rxxxxxx\components, it seems not to be the case in 7?

best regards

I have a seemingly very similar issue. Can you explain, what exactly solved it for you?

In my case it looks like the Component-Server does not start with the studio (http://localhost:8080/api/v1/environment gives no response).

However when I start the server via mvn talend-component:web, it is available immediately.

They are in the maven repository of the studio. If you use the value "global" it is your ~/.m2/repository (or the value in ~/.m2/settings.xml localRepository tag) else it is the local repository of the studio, i.e. <studio>/configuration/.m2.

For the record:

A fresh install of the studio did fix the problem (at least for 50% of us)
