Share my some experience about Ehcache sever here:
Why compile the source codes instead of using the binary?
Because I want to upgrade ehcache core to 2.4.2
You need download source codes of Ehcahe server and build it.Unofortunatelly,I can't build it successfully at first,I think this project is too old.It uses one library for soap security,but this library is deprecated.Finally,I have to delete soap folder from src/main/java,also delete src/test/java folder.
I also modified pom.xml to use the newest jersey-server library,list some changes here:

<parent>
<groupId>net.sf.ehcache</groupId>
<artifactId>ehcache-parent</artifactId>
<version>2.2</version>
</parent>

<dependency>
<groupId>com.sun.jersey</groupId>
<artifactId>jersey-server</artifactId>
<scope>compile</scope>
<version>1.6</version>
</dependency>

Also,we can add some restful web methods to support batch query.I mean get several objects one time by passing a few key parameters.We can bind the database table with Ehcache server too.

I don't suggest passing an Object which implements Serializable interface.Java standard serialization algorithm is complex and slow,the result char array is too large.I implement my own serialization algorithm,it is 2x faster than standard way,and save 2/3 memory.
In my client,just passes the byte array as value to cache server.
This is good idea,because I can compress the byte array before sending it to cache server.

One guy reported a bug for Ehcache server.I tried ,he was right.
Add service.init() in the following method:

public void contextInitialized(ServletContextEvent sce) {
System.setProperty("com.sun.management.jmxremote", "");
LOG.info("Starting JMS MBeanServer");
MBeanServer mBeanServer = ManagementFactory.getPlatformMBeanServer();
ManagementService service = new ManagementService(CacheManager.getInstance(), mBeanServer,true,true,true,true);
service.init();
}

After that,I can monitor the MBeans in EhCache using JConsole.

Wow. These are helpful suggestiong. Thank you :)

Can you please file JIRAs suggesting making these changes part of the code base for everyone?

Cheers!
