Why do I get multiple Java errors when opening MatLab?
显示 更早的评论
When I open MatLab I get the following errors in the command window:
I am running MatLab version 9.2 (R2017a) with Aerospace Toolbox 2.19 (R2017a) on Windows 10. I have Java 1.8.0_144 installed.

Can you look to see if there is a file called hwsmanagement.jar located in C:/Program Files/MATLAB/R2017a/java/jar/ ? The error you are getting is because that file can not be found.

Thank you for taking a look at my question aborghes. I was able to navigate to the hwsmanagement.jar file but a cursor popup told me that it was not part of my path. I was able to add the C:/Program Files/MATLAB/R2017a/java/jar folder (and subfolders) to the path and now when I hover over the file the directory location is shown. However, as you can see when I restart MatLab, the errors still persist. Is there something else I should do?

How were you adding the JAR file to the path?
Have you tried the following?
restoredefaultpath
savepath
Note that this will overwrite your path with the default path.

Because the errors occur before the ">>", this is related to the Java path used during startup. Here is some information about how to add a JAR to the static Java path and make sure that the Java files are "known" at startup instead of added dynamically for each session. Hope this helps!
