Hi,
I hope you guys can help me, I already posted this question on
stackoverflow but did not get any help (which worked). And I need to solve
this problem as quick as possible:
In our firm we migrated to windows 7 (64-bit) and also updated the java
packages (1.6.0_24) and also R (to 2.15). Then I tried to install my
packages which i use daily and one of em is the xlsx package.
But if I load the package I get the following error:
"Error : .onAttach in attachNamespace() Error: .jnew(
"org/apache/poi/xssf/usermodel/XSSFWorkbook") "
I did seth a path variable to the java folder (where the jvm.dll is).
Then I tried to install the XLConnect package (which would not be that
difficult to re-write my code to that package), this package loads without
problems, but if I try to load a workbook an error comes up:
Error: NoSuchMethodError (Java): org.apache.xmlbeans.XmlOptions.
setSaveAggressiveNamespaces()Lorg/apache/xmlbeans/XmlOptions;
Since I've never worked with Java (not as a developer) I have no idea what
I can do to solve the problem.
I hope you can help me! Thank you very much.
Best regards
Rainer
