运行resin时的JMX MalformedObjectNameException问题

When running resin,I get the following error:

"javax.management.MalformedObjectNameException: ObjectName: invalid character @#:@# in value

part of property...". Here is others@# discussion

unix.sh> export CLASSPATH=""unix.sh> bin/httpd.shYou can start httpd with the -verbose option to see the CLASSPATH that is being used when

Resin is started.

With -verbose option,I get environment variables list as follows:java:        C:\Program Files\Java\j2sdk1.5.0\bin\java.exeJAVA_HOME:   C:\Program Files\Java\j2sdk1.5.0RESIN_HOME:  D:\resin-2.1.6SERVER_ROOT: D:\resin-2.1.6CLASSPATH:   D:\resin-2.1.6\classes;D:\resin-2.1.6\lib\resin.jar;C:\Program

Files\Java\j2sdk1.5.0\lib\tools.jar;C:\Program

Files\Java\j2sdk1.5.0\jre\lib\rt.jar;D:\resin-2.1.6\lib\dom.jar;....

I think the reason is the blank in "Program Files",and the error disappear when I move jdk

to a path without blank and reset the values of environment variables above with the path.
