Apparently, the BAR file created by the toolkit by default, places the deployment-descriptor (broker.xml), in a sub-folder of the application that is contained in it, rather than at the top level. This is confirmed by mqsireadbar as well.
mqsireadbar -b App.bar -- returns nothing
mqsireadbar -b App.bar -r ---> returns the deployment descriptor
The CMP API however, does not seem to have any -r equivalent; The documentation states that to obtain the deployment descriptor one needs to query the BarFile object.
https://www.ibm.com/support/knowledgecenter/SSMKHH_9.0.0/com.ibm.etools.mft.cmp.doc/index.html?lang=en
However, this returns a null - this is consistent with the mqsireadbar (without -r),
What's the equivalent of mqsireadbar -r in the CMP ?

The BarFile object for the top level App.bar is not the one you want.
You need to get the BarFile object for App.appzip instead.
That BarFile object will have the deployment descriptor that you are after.
Here's some code that will do the trick:
| Code: |
BarFile barFile = BarFile.loadBarFile("App.bar");
BarEntry appBarEntry = barFile.getBarEntryByName("App.appzip");
BarFile appBarFile = BarFile.loadBarFile(appBarEntry.getBytes(), appBarEntry.getFullName());
DeploymentDescriptor desc = appBarFile.getDeploymentDescriptor();
Enumeration<String> props = desc.getPropertyIdentifiers();
while (props.hasMoreElements()) {
String prop = props.nextElement();
System.out.println("Found property: " + prop);
}
|
All mqsireadbar -r does is iterate over the BarEntry objects in the top level BarFile using getBarEntryNames() & getBarEntryByName().
If it finds an application or library, then it loads it into a new BarFile object as above. |

I have access to the source code, so that helps 
I can't see that process mentioned in the Javadoc for the Integration API anywhere - I'll look at getting it updated. |

I was attempting to use this technique to call setOverride on the deploymentDescriptor.
As per the document i've to call save to make the changes persistent.
Calling save on the top-level barFile has no effect.
Calling save on the bar created from the byte[] throws an exception when save is called ( seems that it expects it to be a file).
Any suggestions on what to do?

Saving in this case is often streaming from the source bar file to a destination bar file...
