"Cannot connect to VM" when trying to Debug [message #300403] Wed, 08 March 2006 16:22 Go to next message

I use winXP, SP2, Eclipse 3.1.1, JDK1.5.0_06, JRE1.5.0_06.
Everything worked fine until a few days ago:
If i want to Debug a (local) Java Application i get the Message "Cannot
connect to VM" when i hit dem "Debug"-Button!!!

I tried with Eclipse 3.0 but there i have the same Problem. In Eclipse 3.0 i
get also an Stack-Trace:
>> Cannot connect to VM
>> java.net.BindException: Address already in use: JVM_Bind
>> java.net.PlainSocketImpl.socketBind(Native Method)
>> java.net.PlainSocketImpl.bind(Unknown Source)

>> org.eclipse.core.internal.jobs.Worker.run(Worker.java:66)


I didn't change any settings concerning windows, eclipse or java. I have no
Firewall installed, except the WinXP-SP2-Firewall. But also when it is not
active the error occours.
I have no idea why there should be an "Address already in use"....this
Problem is annoying...i hope someone can help me!! Otherwise i have to
reinstall my entire system.

Hi Franz-Stefan,

have you tried another port for remote debug already?

No. I didn't know that i can do that and i don't know how i can do that, so:
how can i do that?

Now i noticed that the Help of my Eclipse is also not working. If i want to
run the Help->Help Contents i get an error "Help cannot be displayed. The
embeded application server could not run help web application. Check the log
for details.". I suppose that this error is is related to my "Cannot connect
to VM"-Error....

Choose Menu Run -> Debug
Configure Remote Java Application -> Connection Properties -> Port

Change the vm options when starting the java application (you want to debug)
Here my options for example: -Xms64m -Xmx128m -Xdebug -Xnoagent
-Djava.compiler=NONE
-Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=801 0
