[Resolved] Import (menu or wizard) CSV, Excel and XML doesn't work

Resolved - Rapidminer uses JRE 7, was using JRE 6. Confirmed: Using JRE 7 fixes the problem

I'm currently using the zip-unpacked Java version of RapidMiner to analyse SurveyMonkey responses to open-ended questions, stored as spreadsheets.

I note that attempting to use the import Wizard doesn't work for CSV, Excel or XML. Clicking the menu or button does absolutely nothing - nothing in the log either.

I can import the files manually using the Read Excel or CSV nodes, but as I'm new to the application, would like the assistance of the wizard.

I've investigated the INSTALL.txt file and could find no trace of these configuration files:

[tt] RAPID_MINER_HOME/rapidminerrc
RAPID_MINER_HOME/rapidminerrc.OSNAME
~/.RapidMiner5/<VERSION>rapidminerrc
~/.RapidMiner5/<VERSION>rapidminerrc.<OSNAME>
rapidminerrc
rapidminerrc.<OSNAME>[/tt]

I'm uncertain if this has anything to do with the problem?

Hi,

are you using MacOS? Which version of RapidMiner are you using?

No, Windows 7 (32-bit). It's a company machine, and the restrictions the administrators put on it are the bane of my life, which is why I'm using the Zip version of RM.

Hi,

can you please post the contents of the rm.log file (user/.RapidMiner5/rm.log) after you restarted RapidMiner and tried to open an Import wizard via "File" -> "Import Data" -> "Import Excel Sheet..."?

Marco

The following represents me launching RM, starting a New Process, clicking each of the three options in turn, then shutting down. Must of the content appears to be generated by the inability to contact the update server, it being blocked by the firewall:

Hi,

I don't see anything in your log which would indicate a problem which might cause this issue, which is rather strange. I also could not reproduce the issue on any test machine here, everything works fine, so this might be a little bit tricky to figure out. Can you please start the RapidMinerGUI.bat script from the command line (found inside the RapidMiner5/scripts folder), and paste the whole output here? You can copy & paste from the windows command line via rightclick -> select all and then leftclick in the upper left corner on the icon, go to Edit and then select copy.

Regards,
Marco

It seems those Import options trigger a lot of calls to Java libraries of 'unknown source'

I checked my Java version:


C:\Users\doe-morrisonc\Desktop>java -version
java version "1.6.0_11"
Java(TM) SE Runtime Environment (build 1.6.0_11-b03)
Java HotSpot(TM) Client VM (build 11.0-b16, mixed mode, sharing)

Argh!

In order to use RapidMiner you need a Java Runtime Environment (JRE) version 7

colmoni

Thanks for the help, it pushed me in the right direction for a solution. Really should have RTFM!

Hi,

I have encountered the same problem as colmoni, but the difference is that I'm running Mac OSX. When starting the Java 7 download I get the following message:

"If you download Java 7, you will not be able to run Java content in Chrome and will need to use a 64-bit browser (such as Safari or Firefox) to run Java content within a browser. Additionally, installing Java 7 will disable the ability to use Apple Java 6 on your system".

Is there a workaround for Mac users?

My current Java version is:

java version "1.6.0_65"
Java(TM) SE Runtime Environment (build 1.6.0_65-b14-462-11M4609)
Java HotSpot(TM) 64-Bit Server VM (build 20.65-b04-462, mixed mode)

Thanks in advance.

paulalford,

You can have several versions of JDK installed on your Mac.
Open http://www.java.com/en/download/installed.jsp?detect=jre&;try=1 in your Safari browser (not Chrome)

It will tell you if you have java 1.7. If you do you should see Java in your System Preferences.
Click on Java tab and "View..."
Under Path you'll see where Java 7 is installed.
Edit scripts/RapidMinerGUI script to hardcode JAVA_HOME to point to the location of Java 1.7

It should resolve your issue with RapidMiner and will not affect anything else.
