The class FileToVelocity can format a file/files in a directory using Velocity. There are examples of its use in XmplFileToVelocity1.

1: /** 2: * This method will format all files (Record Oriented Files) 3: * in a directory a using a Velocity Template 4: * 5: * @param layout Record layout of the file 6: * @param lineProvider line provider to create the lines. 7: * note use null for the standard LineProvider 8: * @param records Records to be sent to the supplied Template. 9: * This parameter allows you select which records to 10: * format with the Template 11: * @param inputDirectory input directory to process 12: * @param filter filename filter used to select which files 13: * to format 14: * @param template Velocity template to format the files with 15: * @param outputFile output filename that is to be written 16: */ 17: public void processDirectory(LayoutDetail layout, 18: LineProvider lineProvider, 19: int[] records, 20: String inputDirectory, 21: FilenameFilter filter, 22: String template, 23: String outputFile) 24: 25: /** 26: * process a Record Oriented File using a Velocity Template 27: * 28: * @param layout Record layout of the file 29: * @param lineProvider line provider to use 30: * @param records Records to be sent to the supplied Template. 31: * This parameter allows you select which records to 32: * format with the Template 33: * @param inputFile input file to process 34: * @param template Velocity template to use 35: * @param outputFile output filename 36: */ 37: public void processFile(LayoutDetail layout, 38: LineProvider lineProvider, 39: int[] records, 40: String inputFile, 41: String template, 42: String outputFile) 43: 44: 45: 46:
The following is an example of using FileToVelocity (taken from XmplFileToVelocity1).
1: 2: FileToVelocity fileToVelocity = new FileToVelocity( 3: Constants.SOURCE_RESOURCE, 4: Constants.VELOCITY_OUTPUT_DIR); 5: 6: EdiPo.setCopyBook(copybookInterace); 7: 8: int[] useEdiPO = {EdiPo.getIvr0075hIndex()}; 9: 10: FilenameFilter filter = new FilenameFilter() { 11: public boolean accept(File f, String filename) { 12: return filename.startsWith("tgtorders"); 13: } 14: }; 15: 16: fileToVelocity.processDirectory( 17: copybookInterace.getLayout("EDI PO"), 18: new EdiPoProvider(), 19: useEdiPO, 20: backupDir + "edi\\", 21: filter, 22: "EdiPoHtml", 23: "c:/t/EdiPO.html"); 24:
If you use a LineIOprovider and your own Line class, you can use Getter's & Setter's to access the various fields.
1:## 2:## Generate HTML for a EDI PO file 3:## 4: 5: 6:<table CELLPADDING="3"> 7: <TR><TH BGCOLOR=blue><font color=white><b> $fileName </b></font></TH></TR> 8:</table> 9: 10:<table border="1"> 11: <TR> 12: <TH ALIGN="LEFT" VALIGN="TOP" BGCOLOR="#DADADA">DC</TH> 13: <TH ALIGN="LEFT" VALIGN="TOP" BGCOLOR="#DADADA">Department</TH> 14: <TH ALIGN="LEFT" VALIGN="TOP" BGCOLOR="#DADADA">Purchase Order</TH> 15: <TH ALIGN="LEFT" VALIGN="TOP" BGCOLOR="#DADADA">Before Date</TH> 16: <TH ALIGN="LEFT" VALIGN="TOP" BGCOLOR="#DADADA">After Date</TH> 17: </TR> 18:#foreach( $rec in $records ) 19: <tr> 20: <td>${rec.DcNo}</td><td>${rec.DeptNo}</td><td>${rec.PoNum}</td> 21: <td>${rec.BeforeDate}</td><td>${rec.AfterDate}</td> 22: </tr> 23:#end 24:</table> 25:
Alternatively if you use the generic Line class, you must use the generic getField to get a fields value:
1:## 2:## Generate HTML for a EDI PO file 3:## 4: 5:#set ( $IdxReceiptRh = ${layout.getRecordIndex("ams Receipt RH Receipt Header")} ) 6:###set ( $IdxReceiptRh = 1 ) 7:#set ( $IdxPO = ${layout.getRecord(${IdxReceiptRh}).getFieldIndex("Order No Rh")} ) 8:#set ( $IdxSupplier = ${layout.getRecord(${IdxReceiptRh}).getFieldIndex("Sup Id Rh")} ) 9:#set ( $IdxRctDate = ${layout.getRecord(${IdxReceiptRh}).getFieldIndex("Receipt Date Rh")} ) 10:#set ( $IdxRctTime = ${layout.getRecord(${IdxReceiptRh}).getFieldIndex("Receipt Time Rh")} ) 11:#set ( $IdxDC = ${layout.getRecord(${IdxReceiptRh}).getFieldIndex("Brand Dc No Rh")} ) 12: 13:###Order Index ~ $IdxReceiptRh ~ $IdxPO $IdxSupplier $IdxRctDate $IdxRctTime $IdxDC 14: 15: 16:<table CELLPADDING="3"> 17: <TR><TH BGCOLOR=blue><font color=white><b> $fileName </b></font></TH></TR> 18:</table> 19: 20:<table border="1"> 21: <TR> 22: <TH ALIGN="LEFT" VALIGN="TOP" BGCOLOR="#DADADA">DC</TH> 23: <TH ALIGN="LEFT" VALIGN="TOP" BGCOLOR="#DADADA">Purchase Order</TH> 24: <TH ALIGN="LEFT" VALIGN="TOP" BGCOLOR="#DADADA">Supplier</TH> 25: <TH ALIGN="LEFT" VALIGN="TOP" BGCOLOR="#DADADA">Receipt Date</TH> 26: <TH ALIGN="LEFT" VALIGN="TOP" BGCOLOR="#DADADA">Receipt Time</TH> 27: </TR> 28: 29:#foreach( $rec in $records ) 30: <tr> 31: <td>${rec.getField(${IdxReceiptRh}, ${IdxDC})}</td> 32: <td>${rec.getField(${IdxReceiptRh}, ${IdxPO})}</td> 33: <td>${rec.getField(${IdxReceiptRh}, $IdxSupplier)}</td> 34: <td>${rec.getField(${IdxReceiptRh}, $IdxRctDate)}</td> 35: <td>${rec.getField(${IdxReceiptRh}, $IdxRctTime)}</td> 36: </tr> 37:#end 38:</table> 39:<p> <p>
Finally you can also use getField(String fieldname) of Line class to retrieve field values:
1:## 2:## Generate HTML for a EDI PO file 3:## 4: 5: 6:<table CELLPADDING="3"> 7: <TR><TH BGCOLOR=blue><font color=white><b> $fileName </b></font></TH></TR> 8:</table> 9: 10:<table border="1"> 11: <TR> 12: <TH ALIGN="LEFT" VALIGN="TOP" BGCOLOR="#DADADA">DC</TH> 13: <TH ALIGN="LEFT" VALIGN="TOP" BGCOLOR="#DADADA">Purchase Order</TH> 14: <TH ALIGN="LEFT" VALIGN="TOP" BGCOLOR="#DADADA">Supplier</TH> 15: <TH ALIGN="LEFT" VALIGN="TOP" BGCOLOR="#DADADA">Receipt Date</TH> 16: <TH ALIGN="LEFT" VALIGN="TOP" BGCOLOR="#DADADA">Receipt Time</TH> 17: </TR> 18: 19:#foreach( $rec in $records ) 20: <tr> 21: <td>${rec.getField("Brand Dc No Rh")}</td> 22: <td>${rec.getField("Order No Rh")}</td> 23: <td>${rec.getField("Sup Id Rh")}</td> 24: <td>${rec.getField("Receipt Date Rh")}</td> 25: <td>${rec.getField("Receipt Time Rh")}</td> 26: </tr> 27:#end 28:</table> 29:<p> <p>
