Why do you think it is not deployed?

It was deployed, has an id. You also sucessfully started a ProcessInstace.

Hi,

As an improvement, I am able to see some acripts running when "deploy()" method is being invoked (thro' my java code) in the console of eclipse. Though the activiti process engine is being created and the process instance is started thro' API, I do not see the deployed process definition under "Deployed Process Definitions" in Activiti Explorer.

I had attached the output which I got from the console of eclipse and the java code for your reference. Please help me to fix this issue.

Thanks and Regards,

Your deployment script doesnt use the same database as your activiti explorer instance.

Hi,

Thanks for the comment. I have the same "db.properties" what Activiti Explorer uses in my classpath eclipse with the following details.

db=h2
jdbc.driver=org.h2.Driver
jdbc.url=jdbc:h2:mem:activiti;DB_CLOSE_DELAY=1000
jdbc.username=sa
jdbc.password=

Please let me know the where the problem is!!!

It is an in memory database, so it is bound to the current jvm instance.

Hi,

Can you please elaborate more on how to view the deployed instances in explorer? I am still stuck here. Please help me to fix this issue.

Dear Mr. Martin,

Thanks a lot for your suggestion.

I referred the link which you sent to me. It seems both activiti-rest and activiti-explorer need use the same data base. I ran the command "java -cp h2-1.4.180.jar org.h2.tools.Server -tcpPort 2962" thro' command prompt. I got the below response.

"TCP server running at tcp://10.199.102.134:2962 (only local connections)
PG server running at pg://10.199.102.134:5435 (only local connections)
Web Console server running at http://10.199.102.134:8082 (only local connections)"

I am getting the following exception in the web page with the link "http://10.199.102.134:8082/".

"H2 Console
Sorry, remote connections ('webAllowOthers') are disabled on this server."

Please suggest me how do I overcome this issue.

Thanks and Regards,
Rajendiran R

Thanks Mr. Martin.

I did sync the h2 data base between my activiti API and the explorer one. I am able to deploy the process definition from Activiti API and aable to see the same in h2 database. I ran the h2 database server on server mode which solved my problem.

I am now facing another issue. Though I am able to see the deployed process definition in h2 database (thro' API), I tried to see the same in Activiti Explorer. I am not even getting the login page loaded. I got the below HTTP 505 exception.

Exception

Dear Mr. Martin,

I solved the above mentioned servlet error. I created ExplorerApp servlet and did onload startup at explorer's web.xml. Now I am able to see the deployed process definitions (thro' activiti api) at explorer along with the form data. Thanks a lot for your support.
