Problem(Abstract) |
You are receiving the exception
"javax.jms.MessageFormatException: MQJMS1058: Invalid message property
name: writer-id" when your application passes a message property "Property
Names" containing the "-" (hyphen) character. |
|
|
|
Cause |
Message property names are not allowed to contain certain
characters as outlined below. |
|
|
Resolving the
problem |
Valid property names must begin with a Java™ identifier
start character (any character for which
Character.isJavaIdentifierStart returns true) followed by
Java identifier part characters (characters for which
Character.isJavaIdentifierPart returns true).
From Java Message Service (JMS) specification, section 3.5 Message
Properties:
===========================================================
The Message interface contains a built-in facility for supporting
property values. In effect, this provides a mechanism for adding
optional header fields to a message. Properties allow a client, via
message selectors (see Section 3.8, "Message Selection"), to have a JMS
provider select messages on its behalf using application-specific
criteria.
Section 3.5.1 Property Names
Property names must obey the rules for a message selector identifier.
See Section 3.8.1.1, "Message Selector Syntax," for more information.
Section 3.8.1.1 Message Selector Syntax
A selector can contain:
Identifiers:
An identifier is an unlimited-length
character sequence that must begin with a Java identifier start character;

identifier start character is any character for which the method
Character.isJavaIdentifierStart returns true. This includes '_' and '$'.
An identifier part character is any character for which the method
Character.isJavaIdentifierPart return true. (For other Identifiers
limitation please refer to the JMS SPEC)
===========================================================

the following punctuation symbols:
+ - : ; , = | / \ ( ) [ ] @ # % ! ^ & ~
