Clash with existing Jar files

I am using Matlab R2011a The following code works because the ImmutableList of Google is contained in some jar file listed in JavaClasspath

>> import com.google.common.collect.ImmutableList;

>> w = ImmutableList.of('Hans','Wurst')

My program is a Java project that is also using ImmutableLists. However, I am using version more uptodate. how can I find out what version Matlab is using? How can I determine which jar file is hiding the ImmutableList? How can I enforce Matlab to rank my jar file higher?

Best regards Thomas

Hi,

the jar file containing the ImmutablesLists is:

C:\Program Files\MATLAB\R2011a\java\jarext\google-collect.jar

I think there is no way to force MATLAB to rank your file higher. The only way I see it to remove this jar from the JavaClasspath and add yours. But I wont recommend this since this can lead to MATLAB crashes and/or strange behavior.

Friedrich, thanks for your quick reply

I added an updated guava.jar (google-collect has been retired a while ago) and deleted google-collect.jar. I find it really irritating that MathWorks is producing such a mess with like 300 jar files even in the basic installation. I suggest them to rename the external jar files, e.g. instead of com.google.... they should rename them to com.mathworks.google...

This will remove quite some pain integrating Java tools for me.

Of course, I had to edit classpath.txt...
