hessian访问weblogic服务报NullPoint的问题

[lw9313]

配置后，客户端可以调用服务端的方法，但是在调用后服务端会有个异常：
<2010-11-2 上午11时11分53秒 CST> <Error> <Kernel> <BEA-000802> <ExecuteRequest f

很奇怪，有遇到过这样问题的吗？

I met the same problem, please refer to http://wangxiangblog.blogspot.com/2010/10/spring-v302-learning-note-16-integrate.html

I guess the version of weblogic you are using is older than v10.3.1.

The root case is that hessian closed the activate servlet, while weblogic wants to reuse it as there is keep alive feature in weblogic.

I checked it with oracle, this is the article for oracle's reply and solution:

or switch your weblogic to v10.3.1.

GIVE ME THE SCORE!!!

This is the service request I raised to oracle support for this issue.

hi Sean, <<<--- this guy is weblogic tech support

Attached two files for the test case.

I developed a simple web servcie using hessian and spring framework. The whole source code is zipped in the attached springhessian.zip. And the attached springhessian.war can be dployed to tomcat or weblogic.

The client caller junit class is com.spring.hessian.test.HessianTester. you can find it in springhessian.zip. The reference java library files also can be found in springhessian.war\WEB-INF\lib

There are two remote methods in the junit test class.

This is the correct output I extracted from tomcat console:
Manager----Here is the logic to change email.
DAO----Here is the logic to change email.
Manager----Here is the logic to delete account with ID = 129
DAO----Here is the logic to delete account with ID = 129

This is the output from weblogic:
Manager----Here is the logic to change email.
DAO----Here is the logic to change email.

You can see something is wrong after finishing the first call, then the second call hangs on.

This is the server log I found for the above exception.
