I get the following error when trying to debug a local java application in eclipse.
FATAL ERROR in native method: JDWP No transports initialized, jvmtiError=AGENT_ERROR_TRANSPORT_INIT(197)
ERROR: transport error 202: connect failed: Connection refused
ERROR: JDWP Transport dt_socket failed to initialize, TRANSPORT_INIT(510)
JDWP exit error AGENT_ERROR_TRANSPORT_INIT(197): No transports initialized [../../../src/share/back/debugInit.c:690]
I read that it might be caused by something using the same port as the one eclipse wants to use for debugging, but how do I determine the port number. I couldn't find anything in the error log or the preferences.
Any ideas?
I ran into the same issue and it turns out I was specifying server=n parameter in the jdwp debug string. It turns out that if we specify server=n in the debug connection string, it'll attempt to attach/connect to that port instead of listening on it. Switching to server=y solved my issue. It's documented in the
official jpda documentation.
Maybe it's your antivirus. Are you using avast if so look at this https://feedback.avast.com/responses/eclipse-debug-functionality-not-working-after-upgrade-to-avast-2014
The solution is upgrading to the latest version of avast (http://forum.avast.com/index.php?topic=139606.0)
Please ensure that, the below entry is there in /etc/hosts file (for mac/linux)
127.0.0.1 localhost
Previously I unknowingly commented out this line, so it worked for me after reverting back. Hope this helps.

suddenly, my eclipse does not work in debug model. when click debug button, i got these error messages, and debug failed.
FATAL ERROR in native method: JDWP No transports initialized, jvmtiError=AGENT_ERROR_TRANSPORT_INIT(197)
ERROR: transport error 202: gethostbyname: unknown host
ERROR: JDWP Transport dt_socket failed to initialize, TRANSPORT_INIT(510)
JDWP exit error AGENT_ERROR_TRANSPORT_INIT(197): No transports initialized [debugInit.c:750]
could anyone help, or gives some help.
i have found solution. "unknown host ERROR" in error message is the key.
just because i used switchhost app to change my mac's hosts file. And line of "127.0.0.1 localhost" had been removed.
so, what need to do to solve this problem is adding "127.0.0.1 localhost" to mac's hosts file.
127.0.0.1 localhost
Add the above entry in /etc/hosts file and you should be good.
I have an eclipse workspace with an IBM worklight project running and I want to run another instance of eclipse with another worklight project on different ports. I have modified the server.xml which has the Http ports as follows:
<httpEndpoint host="*" httpPort="10090" httpsPort="10453" id="defaultHttpEndpoint">
<tcpOptions soReuseAddr="true"/>
and also the admin port as follows:
<jndiEntry jndiName="ibm.worklight.admin.jmx.port" value="10453"/>
But when I start the second server, I get the below error:
FATAL ERROR in native method: JDWP No transports initialized, jvmtiError=AGENT_ERROR_TRANSPORT_INIT(197)
ERROR: transport error 202: bind failed: Address already in use
ERROR: JDWP Transport dt_socket failed to initialize, TRANSPORT_INIT(510)
JDWP exit error AGENT_ERROR_TRANSPORT_INIT(197): No transports initialized [../../../src/share/back/debugInit.c:750]
Which port am I missing to change and where do I change that in eclipse?
You may also need to change the debug port for each server.
See here under "Java remote debug...": http://www.ibm.com/support/knowledgecenter/SSHS8R_6.3.0/com.ibm.worklight.dev.doc/devref/c_dev_test_server_and_console.html
You need to open the jvm.options file in Eclipse > Servers > development server. Then edit the port number "10777" to a different one.
While trying to start my Play app locally I am getting a
java.lang.IllegalArgumentException: port out of range:-1
exception followed by a
(*:playRun) java.lang.reflect.InvocationTargetException
message. I can see in the trace the invalid port arg being sent (..../Scala/launcher/sbt-launch.jar" xsbt.boot.Boot "~run -1") but cannot find where to update this argument. There has to be somewhere to override default values. And... No matter what is in the application.conf (http.port) or what I pass on the command line -Dhttp.port I still get the same error. Any info would be enormously appreciated.
I had the same exception and I was in touch with the IntelliJ support team, and got the message it was a bug, because of the https protocol in the open browser field. The url parser cannot handle https and thus not extract the port number.

Since i lost eclipse version of 6.3 i copied eclipse from another mac.
when i tried to run the development server this error shown.
i have also updated to current version of IBM MF still issue exist.
How to fix this issue in mac.
UPDATE:
killall -9 java
Killing java process worked.Thanks
The port is taken.
Try killing the Java process and then start the server again.
in command prompt, run lsof -i :10080
then kill the ports running with kill -9 <port_number>
in the "server" tab in eclipse, delete the "mobilefirst development server"
close eclipse, reopen eclipse, the server should recreate
start the server again
I am working through the YABE tutorial and would like to throw the debugger on to see why the captcha isnt working correctly.
I am using Eclipse and Play 1.2.
Here is the error im getting when trying to run as:
ERROR: transport error 202: bind failed: Address already in use
ERROR: JDWP Transport dt_socket failed to initialize, TRANSPORT_INIT(510)
JDWP exit error AGENT_ERROR_TRANSPORT_INIT(197): No transports initialized [../../../src/share/back/debugInit.c:690]
FATAL ERROR in native method: JDWP No transports initialized, jvmtiError=AGENT_ERROR_TRANSPORT_INIT(197)
Ideas?
Its all there in the message itself!, "Address already in use", ie. the port numbers (8000 or 9000) may be already used/reserved by some other app or you may have a stale Play instance started earlier.
Try changing the JPDA port that Play listens on. It looks like the default port, 8000, is already in use by something else.
You can do this by modifying the "jpda.port" property in "conf/application.conf". Be sure to also modify the Eclipse JPDA launch file (the one that was generated by the play eclipsify command) if that is what you are using to start the debugging session.
