3. (Optional) Select Overwrite existing jar if you want the new converted JAR file to overwrite
the name of a previously converted file.
4. (Optional) Select a different Transactions option.
The HP XML Converter identifies transaction processing in message mappings, which
enables mappings to be executed more efficiently at runtime. (Transactions are defined as
repeated subdocuments nested in an enclosing document.) By default, the HP XML Converter
detects transactions automatically so it can create the most highly optimized mapping.
You can disable auto detection of transactions but still use transaction optimization by
specifying the transaction boundary. This option is useful if auto detection does not produce
optimal acceleration because the converter cannot detect the transaction boundary.
The Transactions options are as follows:
•
Auto Detect Transactions: (Default) This is the normal operation of the HP XML Converter
with full optimization.
• Manual Transactions: Select this option if auto detection does not produce optimal
acceleration and if you can specify a transaction boundary in the documents.
If you select this option you must enter a Target Txn (transaction) Node and a Source
Txn Node. You describe the nodes using a basic XPath with each axis limited to an
element name. You must explicitly specify each step in the ancestry to the node. The
Source Txn Node is the containing element of the transaction in the incoming document.
The Target Txn Node is the mapped destination of the transaction in the outgoing
document.
• Disable Transactions: Select this option to disable transaction recognition and optimization.
Use this option only if the transaction optimization does not produce correct results.
5. Click the Browse button to the right of the Test document field and select a sample input
file to be used to test this Message Mapping. As part of verifying the compile, the test file
will be run through the original Message Mapping and the XTR version and compared
6. Click Compile.
When the compilation process is complete, the application fills in the name of the output
mapping file, as shown in the following figure.
