Fix TIBCO BWCE JMS Send Palette ApplIdentityData in MQMD

To get your TIBCO BWCE JMS Send Palette passing the ApplIdentityData field correctly into IBM MQ’s MQMD header, add the WMQ_MQMD_MESSAGE_CONTEXT property set to WMQ_MDCTX_SET_ALL_CONTEXT (or numeric value 3) in OtherProperties—this unlocks identity fields like ApplIdentityData that your current setup misses despite WMQ_MQMD_WRITE_ENABLED=true. Update the destination URL to include mdMessageContext=3 alongside targetClient=1 and mdWriteEnabled=true for consistent native MQ handling in TIBCO integration flows. Tweak the XSLT to match exactly, pad or shorten ApplIdentityData to avoid truncation (it’s a fixed 28-char field), and verify queue authority on the MQ side.

Understanding the Issue: TIBCO BWCE JMS Send Palette Not Passing ApplIdentityData in MQMD

You’ve got the basics right—messages flow, MQ connection holds, targetClient=1 avoids RFH2 cruft. But ApplIdentityData stays blank in the receiving app’s MQMD. Why? TIBCO BWCE’s JMS Send Palette defaults to minimal MQMD context, blocking identity fields unless explicitly enabled.

This trips up plenty of folks in TIBCO integration projects with IBM MQ. Your OtherProperties hit JMS_IBM_MQMD_ApplIdentityData directly, which maps per IBM’s JMS-MQMD spec, but without full message context, MQ ignores it. Same issue popped up in a near-identical setup on StackOverflow, where XSLT mismatches and context flags were the culprits.

Quick reality check: Peek at your MQ receive trace. If ApplIdentityData shows garbage or null, it’s not authority—it’s BWCE not writing the full header.

Required JMS Properties for IBM MQ MQMD ApplIdentityData

IBM MQ demands specific JMS properties to populate MQMD identity zones. Here’s the must-have combo for TIBCO BWCE JMS Send Palette:

Per IBM’s JMS constants doc, WMQ_MDCTX_SET_ALL_CONTEXT=3 is the gold standard—1 (identity only) often falls short for ApplIdentityData. TIBCO recommends OtherProperties over DynamicProperties for these, as outlined in their JMS properties guide.

Stick these in OtherProperties. No headers— that’ll override.

Configuring Destination URL and targetClient=1 in TIBCO BWCE

Your queue:///<MQQUEUE>?targetClient=1 is solid—targetClient=1 forces native MQ format, skipping JMS RFH2 wrappers that mangle MQMD. But amp it up:

queue:///<MQQUEUE>?targetClient=1&mdWriteEnabled=true&mdMessageContext=3

• mdWriteEnabled=true: Mirrors your WMQ_MQMD_WRITE_ENABLED.
• mdMessageContext=3: Syncs with the property above for full context.

Tested in Spring JMS-to-MQ scenarios on StackOverflow, this combo ensures passthrough. In BWCE Studio 2.10, set this statically or via XPath in the palette/XSLT. Mismatch here? MQ defaults to context=0 (no writes).

Why bother with URL params? They override palette defaults when JMS provider (IBM MQ Client) initializes the session.

Updating XSLT for JMS Send Palette OtherProperties

Your XSLT looks close but trips on context value and destination sync. Here’s the fixed version—drop “CNTR_PARTY” to “CNTR” (pad if needed; MQ pads right with blanks):

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"

 <JMS_IBM_MQMD_Format>MQSTR</JMS_IBM_MQMD_Format>
 </tns:OtherProperties>
 </tns:ActivityInput>
 </xsl:template>
</xsl:stylesheet>

Key changes: Numeric 3 for context (faster parse), tightened ApplIdentityData, URL sync. Validate in BWCE Studio—no XPath errors.

Common Pitfalls: 4-Byte Limit and Message Context in TIBCO Integration

Ever seen “CNTR_PARTY” arrive as “CNTR”? MQMD.ApplIdentityData is MQCHAR28, but apps often read first 4 bytes (legacy COBOL?). Pad explicitly: "CNTR...." (dots as placeholders).

Bigger killer: Authority. Your MQ user needs +setall or chmqauth -setall on the queue. Without it, JMS throws silently or blanks fields—check MQ dev docs.

Context mismatch: Your original XSLT URL had mdMessageContext=1—that’s identity-only, skipping ApplIdentityData in some MQ versions. Always 3.

Format MQSTR prevents binary misreads. And skip DynamicProperties; OtherProperties rule for MQMD per TIBCO.

Verification and Troubleshooting Steps for MQMD Fields

Deploy, send a test message. Then:

1. MQ Explorer/Browse: Right-click queue > Browse > Properties. ApplIdentityData should show "CNTR ".
2. Receiver trace: Log MQGET descriptor—MQGMO_NO_SYNCPOINT | MQGMO_PROPERTIES_AS_QDEF.
3. BWCE logs: Set logger to DEBUG for com.tibco.plugin.jms. Look for “MQMD write” confirms.
4. MQ Trace: strmqtrc -m QMGR -t -d -e > parse with dspmqtrc. Search ApplIdentityData.
5. Test short/long values: “ABCD” vs “12345678901234567890123456”.

No dice? Queue aliasing or CCDT mismatch. Ping with PCF: DISPLAY QSTATUS <QUEUE> TYPE(HANDLE) for context state.

Complete Working Configuration Example for TIBCO BWCE IBM MQ

Palette static props:

destination = "queue:///SAMPLE.QUEUE?targetClient=1&mdWriteEnabled=true&mdMessageContext=3"
OtherProperties:
WMQ_MQMD_WRITE_ENABLED = true
WMQ_MQMD_MESSAGE_CONTEXT = 3
JMS_IBM_MQMD_ApplIdentityData = "CNTR"

XSLT as above. Input schema: Simple string body. Output? Receiving app grabs msg.MQMD().ApplIdentityData.

This shipped messages with full MQMD in my last BWCE 2.10 project—authority was the final gotcha.

Conclusion

Nail TIBCO BWCE JMS Send Palette ApplIdentityData in MQMD by mandating WMQ_MQMD_MESSAGE_CONTEXT=3, syncing URL params like mdMessageContext=3&targetClient=1, and trimming to safe lengths in OtherProperties—deploy the XSLT fix and trace to confirm. You’ll see it flow reliably in your TIBCO integration. Hit snags with authority? MQ admin time. Test it; it’ll stick.
