Eclipse 3.x unable to debug tomcat 5.5 with java 1.6.0_14?

Question

I'm trying to launch and debug tomcat 5.5 with a webapp in java 6.

I have set up JAVA_HOME in the tomcat's eclipse configuration (in "replace environment" mode) but I get the following error:

---

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 [../../../src/share/back/debugInit.c:690]

FATAL ERROR in native method: JDWP No transports initialized, jvmtiError=AGENT_ERROR_TRANSPORT_INIT(197)

---

If I launch directly the startup.bat, it works fine.

Does anybody managed to solve it?

Thanks!

Answer 1

Is this a firewall issue?

Otherwise you need to compare:

• the command line used by the eclipse launcher and
• the one generated by the startup.bat

(through a tool like ProcessExplorer for instance)

Answer 2

I was facing the same issue

adding

-vm C:\Program Files\Java\jdk1.7.0_71\jre\bin\javaw.exe (path of javaw.exe)

in eclipse.ini file make its work

Answer 3

I finally deleted the tomcat configuration and created a new one, with a proper server (tomcat 5.5 + jdk 6) and then everything worked fine.

I suppose the configuration had something wrong...

I mark VonC's answer as the correct for his useful hints.
