You are using a library that doesn't work on App Engine Standard. You need to check with your provider to see if there is an App Engine Standard compatible library you can use, or look at using a different compute environment like App Engine Flex, Compute Engine, or Container Engine.
The give-away is: java.lang.management.ManagementFactory is a restricted class. Please see the Google App Engine developer's guide for more details. As you can see from this JRE Class white-list - it isn't supported in the App Engine Standard sandbox.

I want to know if google app engine supports EJB injection. I did not find any documentation explain this point.
It seems EJB injection is not supported:
There are various APIs and technologies that are not supported by App Engine at present for various reasons. These include:
Enterprise Java Beans (EJB)
See here for more info.

java.lang.NoClassDefFoundError: java.io.FileOutputStream is a restricted class.
Please see the Google App Engine developer's guide for more details.
On the Google App Engine lots of classes are simply not available or give you an SecurityException. You are simply not allowed to read or write files on GAE.
Problem in SOAP connection From the GWT solution to CMIS webServer.
GWT 2.4.0
Google App Engine 1.7.3 is used.
Apache OpenCMIS 0.8 library is used.
i've looked in
consuming SOAP web serives in google app engine and GWT article.
And http://code.google.com/appengine/articles/soap.html. http://code.google.com/p/googleappengine/issues/detail?id=5332
SOAP CMIS connection is made internaly in the Apache OpenCMIS library. (jaxws-rt-2.1.7.jar)
REST Atom Pub connection works nice.
I've got the following error, trying to connect to the SOAP webservice:

I'm try to use WebRowSet in GAE/J App.
javax.sql.rowset.WebRowSet and javax.sql.rowset.CachedRowSet are in JRE White list for GAE.
When i deploy my app to gae i see the error:
com.sun.rowset.CachedRowSetImpl is a restricted class. Please see the Google App Engine developer's guide for more details.
Which implementation may i use in GAE for WebRowSet ?
AFAIK, this is only available if you are using Google Cloud SQL. Did you enroll?
I want to access to an external MySQL server from my server using GWT, I added the mysql-connector jar to the build path and in war/WEB-INF/lib
Although I get this exception:
java.lang.NoClassDefFoundError:
com.mysql.jdbc.Driver is a restricted
class. Please see the Google App
Engine developer's guide for more
details.
Any ideas? Would jdbc driver be on a black-list?
App Engine doesn't support JDBC. Maybe your project is set to target App Engine. If you're using Eclipse, right click the project, choose properties, and under "Google>App Engine" deselect "Use Google App Engine".
It seems Google has not yet released JDBC support..
