javascript debugger

billmce

Can someone confirm that the javascript debugger (http://localhost:8080/alfresco/service/api/javascript/debugger) is not working in Community 3.2.

If there is a work-a-round I'd appreciate it … very frustrating trying to develop some scripts in the dark.

Thanks in advance.

Works fine - trust me, it's one of the first things we'd notice if it broke!

When you say it's not working, what do you mean? If it's not picking up breakpoints or loading scripts, then try resetting webscripts to clear the cache. The debugger can't attach to scripts after they've been compiled.

Thanks,
Mike

I'm glad it's working – but this is what we get when trying to start the debugger (on two separate installs of 3.2R).

Anything in the log file? You're not trying to launch the debugger on a headless server by any chance? The debugger uses Java Swing for the GUI.

Thanks,

As far as headless goes … we're testing with virtual machines. Linux, Opensuse. I've worked with it two ways.
a) I've VNC'ed into it.
b) In the VM server console I've started an X session

mikeh

Nope, works fine here - again, check you're not on a headless server O/S

Hi,

I am also a newbie to using Alfresco, and have not been able to enable the debugger in either Alfresco or share (http://127.0.0.1:8080/alfresco/service/api/javascript/debugger or http://127.0.0.1:8080/share/page/api/javascript/debugger). I am using Windows 7 32-bit, Enterprise Version 3.3.2 on my local workstation/laptop.

Any help would be appreciated, it is difficult to be not be able to debug JS when writing new webscripts.

I get the following error:

Can you post the complete null ptr exception?

Hi Kevin,

Sorry I assumed the forum would email me if someone replied. I have an answer to this problem based on help from Alfresco Network Support. The debugger doesn't work when Alfresco is run as a service. I made all Alfresco services (alfrescoMySQL, alfrescoOpenOffice, alfrescoTomcat) Manual Start up type, and have 4 files saved in the Alfresco folder that support alfresco start/stop, only thing need to change is the JAVA_HOME in setPaths file.

1. alf_start.bat:

@echo off
rem —————————————————————————
rem Start script for the Alfresco Server
rem —————————————————————————

call "%~dp0alfresco.bat" start %1‍‍‍‍‍‍

2. alf_stop.bat:

@echo off
rem —————————————————————————
rem Stop script for the Alfresco Server
rem —————————————————————————

call "%~dp0alfresco.bat" stop %1‍‍‍‍‍‍

3. alfresco.bat

@echo off

rem Start script for the Alfresco Server

Great! Thanks Judy. It worked for me.

Sorry for reposting, but there are 2 similiar topics.
What version of windows do you have? I'm not successful with running javascript debugger.. I have windows 7 64 bit. Enabling the debugger results in:

at java.lang.Thread.run(Thread.java:619)
aused by: java.awt.HeadlessException
at java.awt.GraphicsEnvironment.checkHGadlGss(GraphicsEnvironment.java:1

at org.mozilla.javascript.tools.debugger.SwingGui.cinit>(SwingGui.java:1

I start manually by using catalina start, so windows services limitation is not the case.

Did anyone achieve success in running javascript debugger on win7 64 bit?

sonata82

I have started the JavaScript Debugger successfully on a Windows7 64 bit.

Alfresco runs from IntelliJ using the same JAVA_OPTS as mentioned above and running catalina.bat.

Hi!

In what path should I save the four file? like the setPath, alf_start.bat?

Thank you,
