StringBuffer problems in custom Adapter Modules

[Former Member]

Hi all,

I'm facing this weird problem while creating an adapter module:

whenever I use in my code a StringBuffer object I get an exception in the adapter runtime; notice that when I test it on my machine it works just fine.

Even surrounding every piece of code with try-catch blocks I wasn't able to get the exact Exception, which appeared only as a com.sap.engine.services.ejb.exceptions.BaseTransactionRolledbackLocalException.

Using a simple String object instead of the StringBuffer one the exception didn't appear again and the module worked.

Is this behaviour a normal one or is there something wrong?

thaks in advance for help,

Daniele

Daniele ,

this sounds really funny:)....

but let me tell you that I have used Stringbuffers extensively in all my adapter modules to build the payload string and it for sure is not a problem with usage of StringBuffer.

check out for all kind of logical errors wrt initialization / runtime exceptions being thrown....again...It cant be a problem wih StringBuffer...

Hi Amol ah thank you for the reply.

This sounds funny also to me, but I'm not the only one in the office having the same problem.

The strangest thing is that a brutal replacement of StringBuffer with String cancels the error...

Hi Daniele,

I think you should check that the versions of your local jdk is alligned with the java vm version of your XI.
