The EXPDTA, EXPSPL and IMPDTA no longer function after upgrading to 3.7. The Java error is most likely java.lang.UnsupportedClassVersionError
The EXPDTA, EXPSPL and IMPDTA commands all require Java 1.5 or higher. Previously required Java 1.4
The first thing to do is check to see if any newer versions of Java are installed on the iSeries. It's possible that a newer version of Java is installed but not default version(To view the default version of Java use command RUNJVA CLASS(*VERSION) ). Use the command:
GO MENU(LICPGM) - Select option 10 Look for Licensed Program 5722JV1.
Here is an example of what you might see.
5722JV1 *COMPATIBLE Java Developer Kit 1.3
5722JV1 *COMPATIBLE Java Developer Kit 1.4
5722JV1 *COMPATIBLE Java Developer Kit 5.0
5722JV1 *COMPATIBLE J2SE 5.0 32 bit
5761JV1 *COMPATIBLE Java Developer Kit 6
5761JV1 *COMPATIBLE Java SE 6 32 bit
5761JV1 *COMPATIBLE Java SE 6 64 bit
If there is a higher version installed you have 2 options.
1). Specify the Java version on the Surveyor command SURVEYOR/EXPDTA JAVAVER(1.5)
2). Change the default Java version on the iSeries. Edit file /QIBM/UserData/Java400/SystemDefault.properties (You can use Surveyor to do this). Specify the java.version property:
java.version=1.5
After saving the file you will have to change the CCSID to 1252
CHGATR OBJ('/QIBM/UserData/Java400/SystemDefault.properties') ATR(*CCSID) VALUE(1252)
If there is not a higher version installed, either install one or downgrade to Surveyor 3.6
Downgrade to 3.6
