Help calling Java from Studio

[Tiki]

I wanted to re-use some Java functions that were developed for SageMC to make some improvements to the stock Sage STV, but I'm stuck...

I added a call to sagemc_Global_filterMediaFileByPath() to the SageTV3.xml STV in studio and hard-coded the arguments for testing purposes (See attached jpg for picture of studio code). When I run the STV, this function seems to have no effect and I get a bunch of errors in the debug log, specifically "Unknown Method Error" Here's a snippet of the debug log:

I have the sagemc.jar file in the SageTV\JARs folder and this function works with the SageMC STV loaded (Though the arguments are not hard-coded there and get passed-in by the dynamic menus).

Any ideas on what I could be doing wrong?
Does this error indicate that Sage cannot find this function or doesn't see the JAR file?

[GKusnick]

If it's in the JARs folder, Sage should be able to find it. So your problem is most likely a spelling or capitalization error (Java is case-sensitive), or you've got the package or class name wrong, or you're passing the wrong types of arguments so that overload resolution fails (i.e. Sage can't find a method with that name that accepts those argument types). One example of bad argument types is forgetting to pass in an instance of the class for non-static methods.

I'm not familiar with SageMC support libraries so I can't help with the specifics, but those are the sorts of errors you should be looking for.

[Tiki]

I copied and pasted from the SageMC stv. Here is the original widget code from SageMC:

AllVidFiles = sagemc_Global_filterMediaFilesByPath(AllVidFiles, PathFilterExprs, PathFilterExcludes)

The values for PathFilterExprs and PathFilterExcludes get set by the Dynamic menu code. Here is the code from the SageMC_menu.xml:

            <evalExpression>AddStaticContext("PathFilterExprs", new_java_util_ArrayList())</evalExpression>
            <evalExpression>java_util_List_add(PathFilterExprs, "G:\\Imported Videos\\")</evalExpression>
            <evalExpression>AddStaticContext("PathFilterExcludes", true)</evalExpression>

I just noticed that the PathFilterExprs argument appears to be an array. Could this be my problem?

[GKusnick]

What's being passed in that code sample is an ArrayList, which is not the same thing as an Array but is actually a subclass of List. What you're passing (according to the exception log) is an Array, which is not compatible with List. So that could conceivably be your problem. Again, I'm not an expert in that library, so you'll need to check whatever documentation came with it to see what type it's expecting, or wait for someone more knowledgeable than me to post.
