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

[Former Member]

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

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
