Thiago Assis commented on OLINGO-150:
-------------------------------------
first of all, thanks for your answer !
To use the olingo with Google App Engine i have to change two main points:
1 - The JAX-RS framework
The Google App Engine not support JAX-RS 2.0, the only JAX-RS implementation
officialy compatible is Jersey 1.1.5 :( !
There is any way to decoupling olingo fram JAX-RS, for example, develop a
servlet to do the JAX-RS job ? I was trying this posibility, atached to this
issue is my servlet code.
2 - The multthread and the JVM restricted classes
When i call my solution using my servlet code and the apache olingo i get ther
error below, in
org.apache.olingo.odata2.core.ODataContextImpl.startRuntimeMeasurement at line
measurement.setMemoryStarted(ManagementFactory.getMemoryMXBean().getHeapMemoryUsage().getUsed());
java.lang.NoClassDefFoundError: java.lang.management.ManagementFactory is a
restricted class. Please see the Google App Engine developer's guide for more
details.
