Hello, all: I need to create Excel workbooks in batch from RPG, and am just *this* far away from getting Geert Van Landeghem's tutorial on calling POI methods in RPG running. Two items have me completely stumped, though. Can someone please point me in the correct direction? See http://www.jasservices.com/articles/as400/001_genexcel.htm. 1) Using the example RPG at the bottom of his page, my compiler spits-up on the "writeWB(wb:outFile);" statement, issuing a "*RNF7030 The name or indicator WRITEWB is not defined." error message. If I understand correctly (and that is a big leap) it appears that "writeWB" is actually a Java method and must be prototyped for RPG to call it. It seems like "writeWB(wb:outFile);" has two parms, so I prepared the following PR. Now the compiler complains about "*RNF5406 The call passed fewer parameters than the prototype indicates are required." What am I misunderstanding about Java prototypes? * // WorkBook.write() D writeWB PR EXTPROC(*JAVA D :'org.apache.poi.hssf.usermodel- D .HSSFWorkbook' D :'write') D parm O CLASS(*JAVA D :'org.apache.poi.hssf.usermodel- D .HSSFWorkbook') D parm O CLASS(*JAVA D :'java.io.FileOutputStream') 2) The program actually runs if all the POI-related lines are commented out. An empty "foo.xls" file is created in the output directory so I know the java.lang.* and java.io.* functions work, but I receive the following runtime error when the program is run with the "wb = createWB()" uncommented. "Java exception "java.lang.NoClassDefFoundError: " "org/apache/commons/logging/LogFactory" when calling method "<init>" with" "signature "()V" in class "org.apache.poi.hssf.usermodel.HSSFWorkbook". " The iSeries has JDK1.3 and runs V5R1 with recent PTFs. *SYS CLASSPATH is set to ".:/JavaUtil/POI/POI.jar", and I can see that exact item (spelling and caps are correct) is present when I peek into POI.jar with WinZip. Actually, I receive the same runtime message when the CLASSPATH is "Foo" or *NONE, so it appears that RPG is ignoring the CLASSPATH entirely. Since the JVM is being started inside of RPG, is there some parameter that controls where RPG resolves the CLASSPATH? Does anyone know of a way (example code would be greatly appreciated) to see what the CLASSPATH is during debug? Is there anything suspicious about the "signature ()" statement? Why do I have so many questions? Many thanks JK
