I cant seem to be able to get this to work. Please help.
Say I have 4 flows deployed under an EG, There is a jar file called common.jar that gets deployed with each of the 4 flows. Each deploy overwrites the jar I would think.
Now when I want to remove a flow, I don't want to remove the jar unless this is the last flow under the EG in which case I want to wipe it clean.
I am trying to get this to work using CMP API.
This is what I have I have tried
First I get a list of all deployed objects
| Code: |
Enumeration<DeployedObject> depObjs = null;
depObjs = eg.getDeployedObjects();
|
Then I get a count to initialize a DeployedObjects array
| Code: |
while(depObjs.hasMoreElements()){
DeployedObject depO =depObjs.nextElement();
depCnt = depCnt +1;
}
|
depCnt holds the count
Now I initialize a DeployedObject Array
| Code: |
DeployedObject[] depObjArray = new DeployedObject[depCnt];
|
Then I loop through the deployed objs enumeration again to populate the array
| Code: |
while (depObjs.hasMoreElements()){
DeployedObject depO =depObjs.nextElement();
depObjArray[arrayCnt] = depO;
arrayCnt = arrayCnt +1;
}
|
Now when I have just one flow and one jar left, I see them in the array that I just populated, I see one object as messageflowProxy and another one as messageDependant..something like that
Anyway, now when I try to use this array to remove everything under the EG using the below
| Code: |
deployResult = eg.deleteDeployedObjects(depObjArray, DeployVariables.deployTimeOutSecs);
|
It fails deploy. All I see in the deployresult is the failure to deploy message nothing more. Not sure what I am doing wrong here. |

Shouldn't you be able to get the array to tell you how many elements it has...
? |

Have you checked the content of your array and any of the sublevels.
I have not played with delete yet, but there are many levels below the eg and you need to check what you can delete, and you need to delete it, like if you were doing it through the broker explorer (or the web proxy).
- eg
- applications
- flows
- libraries
- flows
- message models
- message sets
- message models
- message sets
- flows
- message models
- message sets
Have fun

I think I understand what you are saying.
The EG currently has one flow (.cmf) and one jar(common.jar)
when I do the eg.getDeployedObjects(); I see only these two.
then I build my depObjArray array which also only has two entires.
both are of type deployedObject. Like I had mentioned one is of type messageflowproxy(.cmf file) and the other one for the java jar.
Now as per the API documentation I just need to pass this array to the delete command. that is what I did but doesn't work. |

| Is there a specific reason you don't want to simply delete and recreate the EG itself? |

Care to post the finished code (or at least an obfuscated sample) for the benefit of future readers?

Looks fine, but did you try it with
dpo.getName() for populating your array instead of dpo.getFullName()???
You might also want to look at the getFileExtension() method...
Now other things to check: Do you have somewhere a beginUpdate() that would prevent the updates from happening immediately?
