Hello!
My software is:
1) Tamino 3.1.1.1
2) Windows 2000 Professional with SP2
3) jdk 1.4.0
4) TaminoClient.jar, TaminoAPI4J.jar
I have tried to compile source code by using command:
javac ProcessXMLGreeting.java,
Unfortunately I got the following message error:
-----------------------------------------------
“ProcessXMLGreeting.java:139: reference to TAccessFailureMessage is ambigious, both class com.softwareag.tamino.db.API.common.TAccessFailureMessage in com.softwareag.tamino.db.API.common and class com.softwareag.tamino.db.API.accessor match TAccessFailureMessage accessFailure = accessorException.getAccessFailureMessage();
Note: ProcessXMLGreeting.java uses or overrides a deprecated API.
Note: Recompile with -deprecation for details.
1 error”
-----------------------------------------------
What should I do to compile this java source code successfully?
Thanks in advance!
Regards
Dariusz Baumann
PS.
Here is this source code:

/
|| Example for the Tamino API for Java
||
|| It is assumed that a Tamino database called “myDB” has
|| been created and is running.
|| For storing data the default collection ino:etc is used
|| which should only be used for examples/test code.
|| We do not recommend this for real applications.
||
|| The following tasks are performed:
||
|| - establish a connection to the Tamino database
|| - obtain an XML accessor
|| - start a local transaction mode and
|| o retrieve first object stored
|| o update object just inserted
|| o on success commit transaction otherwise roll back
|| - switch back to auto-commit mode
|| - query updated document
|| - delete document
|| - close the connection

It seems that you are using the new Tamino API v3.1.2. The TAccessFailureMessage class has been deprecated and become an interface in the com.softwareag.tamino.db.API.common package and the methods of TAccessorException have also been deprecated. Unfortunately the deprecated TAccessFailureMessage class still remains in the TaminoAPI4J.jar file causing the ambiguity.
This explains the compilation errors suggesting using java -deprecation and the ambiguity as well.
The javadoc suggests using the TException.getRootCause() method instead.
