UFL 'u2lbcode.dll' that implements this function is missing

Former Member — Mon, 04 Mar 2019 16:01:20 GMT

Hi,

I'm trying to develop an application with SAP Crystal Reports, developer version for Eclipse ver 2.0.24.

When I try to run a report with barcode I've got the error:"

UFL 'u2lbcode.dll' that implements this function is missing".

I've developed my application starting from CRJavaHelper class.The others kind of report work well. In the path

C:\eclipse\plugins\com.businessobjects.crystalreports.crsdk.libs_12.2.225.r3524\lib I can find the library

com.azalea.ufl.barcode.1.0.jar, and I can see that in the package explorer in Eclipse. Other information:

I'm runnig my project on Windows 7 64bit.

Someone can help me? Because I don't know how to solve it.

Thanks in advance

It appears your report was designed using the C ufl (u2lbcode.dll). You will need to change the report to use the java UFL.

you can set the classpath for the java UFL in the crconfig.xml file and then change the barcode from the one in the u2lbcode.dll to the one in the JAR using the CR designer.

Thanks for reply.

Please can you show or tell me how to do?

I suppose that I have to write the classpath here:

(crconfing.xml file in Crystal Report installation, not in sdk Eclipse for developer!?)

C:\eclipse\plugins\com.businessobjects.crystalreports.crsdk.libs_12.2.225.r3524\lib\com.azalea.ufl.barcode.1.0.jar</classname>
<classname> </classname>
</ExternalFunctionLibraryClassNames>

but I don't know how to change u2lbcode.dll version.

Please another question. Do you know if this library solve formulas for these kinds of barcode?

the list:

Code 39, Extended Code 39, Code 128, Code 128 auto, AI detection for GS1-128, Interleaved 2 of 5, Codabar, UPC-A, UPC-E, MSI, EAN-8, EAN-13, Code 11, Code 93, Industrial 2 of 5, USPS Intelligent Mail IMb, Postnet & Planet.

In particolar:

- Code 39, Extended Code 39;

-Code 128, Code 128 auto;

-Interleaved 2 of 5;

-Industrial 2 of 5.

Thanks a lot in advance for your help.

Try the instructions in the following PDF. It is a bit old, but the instructions should still be the same.

https://archive.sap.com/kmuuid2/400bcc18-6864-2b10-2c9c-88d352315eb0/Crystal%20Reports%20XI%20-%20Java%20User-Defined%20Function%20Libraries%20(UFL)_0_.pdf

I'm not sure on the full list of barcodes. Someone with a deeper knowledge of CR design would have to answer that.

thanks for the document.

I tried it, but I haven't been able to make the UFL file jar. Because I never made before, please could you help me?

I did these steps:

1) Add external JAr (CrystalReportsRuntime.jar, CrystalCommon2.jar) in my new project;

2) I wrote the code;

3)I made a jar file from Eclipse;

4)In the previuos step I saved my jar file as com.azalea.ufl.barcode.1.0.jar, exactly the same the original file, and put it in the same path.

5)I ran my project wth the report but didn't work.

this is the code that I wrote:

// FUNCTION LIBRARY

Hi,

I am facing similar issue in my application. I am reading existing *.rpt file in java application using crystal report java plugin. The back-end code of these *.rpt files are written in ".net" where it try to call IDAutomationQRCodeEncoderQRSet() and this function not present in crystal report library. I have pasted .net code segment here for reference.

Dim Segments As Number

Segments = IDAutomationQRCodeEncoderQRSet(DataToEncode, ProcTilde, EncMode, Version, ErrorCorrectionLevel)

For i = 0 to Segments

CompleteBarcodeString = CompleteBarcodeString & IDAutomationQRCodeEncoderQRGet(i)

Next i

Formula = CompleteBarcodeString

Because of above issue portal showing below error:

ErrorException in formula '{@qarcode2}' at 'IDAutomationQRCodeEncoderQRSet': UFL 'u212com.dll' that implements this function is missing.

I need your guidance to fix this crystal report issue. Please advice

Regards,

Amit Jha
