[tcljava-user] JACL - convert Tcl string to java int.

[<PFi...@hb...>]

Running Tclblend 1.3.2 on Windows XP.

Writing JACL script to send/retrieve messages to IBM MQSeries on 
Mainframe.

Java code looks like;

qMgr = new MQQueueManager(qManager);
// Set up the options on the queue we wish to open...
// Note. All WebSphere MQ Options are prefixed with MQC in Java.
//##### openOptions is defined as integer ####. 
int openOptions = MQC.MQOO_INPUT_AS_Q_DEF |
MQC.MQOO_OUTPUT ;

// Now specify the queue that we wish to open,
// and the open options...
MQQueue system_default_local_queue =
qMgr.accessQueue("SYSTEM.DEFAULT.LOCAL.QUEUE",
openOptions); 

JACL code looks like.

set MQQueueManager [ java::new com.ibm.mq.MQQueueManager XXXX ]

set queueName      XXX.XX.XXXX.0059.XXXX
append openOptions MQC.MQOO_OUTPUT 
append openOptions " | " 
append openOptions MQC.MQOO_INPUT_AS_Q_DEF

set accessQueue [ $MQQueueManager accessQueue $queueName $openOptions  ] 

##################################333

Calling the accessQueue method generates the error:

----------------------
expected integer but got "MQC.MQOO_OUTPUT | MQC.MQOO_INPUT_AS_Q_DEF"
    while executing
"$MQQueueManager accessQueue $queueName $openOptions  "
----------------------

$openOptions needs to be defined as an integer but it's not being 
converted in the method call. 

Doco says:

"Tcl values are also be converted to Java objects and primitive Java types 
when they are given as arguments to Java commands. The default conversion 
for all Tcl values is a java.lang.String object. To override this default 
a full signature must be provided for Java method invocations". 

java::info method for MQQueueManager returns "{accessQueue 
java.lang.String int}".

I tried "set accessQueue [ $MQQueueManager { accessQueue java.lang.String 
int } $queueName $openOptions  ] "

and got:

expected integer but got "MQC.MQOO_OUTPUT | MQC.MQOO_INPUT_AS_Q_DEF"
    while executing
"$MQQueueManager { accessQueue java.lang.String int } $queueName 
$openOptions  "

How do I specify the full signature for method invocations do enable this 
conversion? 

Regards.
