java.lang.ClassCastException on Weblogic 12.1.2 #24

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?

1. Install and configure WLS 12.1.2
2. follow the install steps provided
3. run the commands

What is the expected output? What do you see instead?

Instead of printing the information i get

java.lang.ClassCastException: java.lang.String cannot be cast to java.lang.Long|

What version of the product are you using? On what operating system?

OS:   Red Hat Enterprise Linux Server release 6.3 (Santiago)
WLS:  12.1.2.0.0
JAVA: java-1.7.0-oracle-1.7.0.17-1jpp.1.el6_4.x86_64

Please provide any additional information below.

If i provoke an error (no authentication, wrong port, wrong/no username) 
everything works as expected - means i get the corresponding documented error.

I also have this problem testing wlsagent-r185 on WLS 12.1.3 running on JDK8. I 
will see the code and try to help on this issue... I'm guessing maybe now the 
MBean attribute values obtained from JMX calls are not numeric anymore.

$ wget -q -O - 'http://localhost:5677/wlsagent/WlsAgent' 
--post-data='hostname=localhost&port=7001&username=weblogic&password=Pa$$&jvm=Us
edMemory,80,90'

I don't think this a problem getting the MBean attribute values... apparently 
it is a problem during the creation of WLS JMX Connector:

I agree with tiago.j....@gmail.com findings.. looks like values are still 
returned as long but connecting MBean value is changed..

I am really from admin side, don't know much about the code..

if anyone has worked on this to fix issue or any work around, please do share 
so that others can get benefit... even comments or suggestions welcome, we may 
get some idea to fix it..

this tool is really awesome but does not work on WLS 12...

Thanks in advance

Hi everybody!
I've just figure out how to fix problem: need to modify init() method in 
WLSProxy class:
1. change Map<String, String> map = new HashMap<String,String>() to Map<String, 
Object> map = new HashMap<String,Object>()
2. change map.put("jmx.remote.x.request.waiting.timeout", "20000") to 
map.put("jmx.remote.x.request.waiting.timeout", 20000L)
3. build application with ant (perhaps, you should rename jar file from 
wlsagent.jar to wlsagent-r185.jar)
4. run application and use
After these modifications it worked on Weblogic 12c
