Got it to work, but more thru random trying of things and reviewing all my settings.

I discovered 2 things after reviewing my debug configuration. One was when I

set up my project it was using the JRE for the java classes instead of the

JDK. The other was I needed to add the actual eclipse workspace to the

source tab using the workspaces option in the dialog. After fixing all of

that it was good. I am not sure why it wouldn't find the source when I went

to the workspace folder after getting the source not found error, but I

think adding the src folder as a workspace in the dialog instead of as a

file made the difference. Thanks for your help.

Hi Arlene,

I haven't heard from you in a while so I am just checking back in to see if you were able to move past this issue. Thanks!

Hi Arlene,

It looks like eclipse is unable to find the source of the auth file for whatever reason. A quick search turned up a few results in google, this one seems to be a similar issue to what you are seeing as well as a possible fix:

Please let me know if that works for you. Thanks!

I am trying to debug the custom authentication example plugin. My question is more about the eclipse debugger I think. When the debugger hits a breakpoint in the java code I get a screen in the debug view that says "source not found" followed by a button that says "edit source lookup path...". No matter how many times I edit the source lookup path (or even if I don't) it keeps coming back with the same screen (see attached)

I don't get any error messages or console messages. I have debugged a regular helloworld java application without this happening.

Not sure where to begin to figure out what setting or setup item may have caused this.

Well after much diddling around I got this to work. There were a number of newbie issues to get around. When I have everything cleaned up I will try to post more complete instructions so others don't have to go thru the pain..

I had to do a couple of changes:

The server was set to default deploy webapps to the wtpwebapps in tomcat. When creating the jvm we had the clearspace war file in the tomcat webapps directory with options to autodeploy. I had to change the deploy path of debug server to webapps instead of wtpwebapps. When I would restart the server the launch configuration was set to append the environment to the native environment. I think that this was causing the extra jvm opts to be appended every time I made an update. That all stopped when I redid the server to deploy to the webapps dir
I moved the -server option so it was on the second line and the -Dcatalina.base="C:\Program Files\Apache Software Foundation\Tomcat 6.0" was on the first line. Dont' know why but this stopped the issue with catalina.base being repeated at the end

here is the working vm arg:

-Dcatalina.base="C:\Program Files\Apache Software Foundation\Tomcat 6.0"
-server
-Djive.ws.disabled=true
-Dcom.sun.xml.bind.v2.bytecode.ClassTailor.noOptimize=true
-Xdebug
-Xnoagent
-Djava.compiler=NONE
-Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=8000
-XX:MaxPermSize=512m
-Xms512m
-Xmx1024m -Dcatalina.home="C:\Program Files\Apache Software Foundation\Tomcat 6.0" -Djava.endorsed.dirs="C:\Program Files\Apache Software Foundation\Tomcat 6.0\endorsed" -Dwtp.deploy="C:\Program Files\Apache Software Foundation\Tomcat 6.0\webapps"

Thanks for bearing with me. Now that I have the debugger working it is very nice

Hi Arlene,

I've never done remote debugging with the embedded tomcat, but with a standard tomcat, it's like this:

I create a "debug.cmd" batch script to start tomcat for me:

SET JAVA_HOME=c:\path\to\jdk

SET JAVA_OPTS=-Dcom.sun.xml.bind.v2.bytecode.ClassTailor.noOptimize=true -Xmx512m -Dlog.debug.enabled=true

SET JPDA_OPTS=-Xdebug -Xrunjdwp:transport=dt_socket,address=8000,server=y,suspend=y

CD c:\path\to\tomcat

CALL bin\catalina.bat jpda start

Then I connect the remote debugger in Eclipse to localhost:8000.

The embedded tomcat server should be more or less the same.

The JDWP error sounds like it's related to this bug: http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6476706, and should be nothing to worry about. Setting the JAVA_HOME explicitly to the JDK may correct the issue.

Regards,

Seth

Getting closer..

BTW I had the dt_shmem because I read that it was what is used for windows, but I switched it back.

I fixed the environment to use the JDK instead of the JRE.

The server starts in about 2 min.. It gives this error when I stop it:

INFO: Stopping Coyote HTTP/1.1 on http-8080

ERROR: JDWP Unable to get JNI 1.2 environment, jvm->GetEnv() return code = -2

JDWP exit error AGENT_ERROR_NO_JNI_ENV(183): [../../../src/share/back/util.c:820]

still it is adding extra lines to the end of the jvm arguments:

-server
-Dcatalina.base="C:\Program Files\Apache Software Foundation\Tomcat 6.0"
-Dcatalina.home="C:\Program Files\Apache Software Foundation\Tomcat 6.0"
-Dwtp.deploy="C:\Program Files\Apache Software Foundation\Tomcat 6.0\wtpwebapps"

I did a netstat -a to check the port to see if 8000 is listening and this is what I saw(I x'ed out machine name):

TCP    XXXXXXXXX:2299     localhost:8080         CLOSE_WAIT
TCP   XXXXXXXXX:2368     localhost:8000         ESTABLISHED
TCP   XXXXXXXXX:8000     localhost:2368         ESTABLISHED

Is this ok? I am not sure of the exact sequence to debug the plugin. Do I open the web page to get it to debug? When I did that nothing happened and when I just tried pressing run in the debug perspective I got this:

java.net.ConnectException: Connection refused: connect
at java.net.PlainSocketImpl.socketConnect(Native Method)
at java.net.PlainSocketImpl.doConnect(PlainSocketImpl.java:333)
at java.net.PlainSocketImpl.connectToAddress(PlainSocketImpl.java:195)

at java.lang.Thread.run(Thread.java:619)

sorry to keep asking these newbie questions, but we are the first in our organization to set this up and have previously only done development in .net so everything is new. Thanks for your patience.

Hi again,

Also, another part of your issue is that you changed JVM arguments. Specifically you changed this:

-Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=8000

to this:

-Xrunjdwp:transport=dt_shmem,server=y,suspend=n,address=8000

I believe that you should be using dt_socket. Thanks.
