exact same problem running the same version of javasnoop on OS X

This can be caused by a number of different things. It's very likely there's a
stack trace or error messages in the Java console (System.out) of the
application to which you're attaching.
It's very likely it's a security problem - are you sure you're starting up the
JavaSnoop startup script before the target program? The startup script turns
off security, which is needed for the agent to function.

If no one comments further in a week or two I'll assume they were Java
security-related errors and I can close this ticket.

Hi,
I've just has an instance of this issue. the application I'm looking at is a
browser-applet based one.
Start javasnoop (using startup.bat) first, then launch the browser and
authenticate to the application (which leads to the applets being loaded), and
I get the "agent failed to initialize" message.
I've tried attaching to other java processes running on the system at the same
time (burp suite) and that works fine, so I don't think it's a general problem
with Javasnoop but perhaps some issue attaching to applet based programs?
Trying to attach to the process gives the

Guys,
Thanks for sharing your idea.
When I'm trying to attach a process. I'm getting the same error as you "Could
not initialize agent: Agent JAR loaded but agent failed to initialize".
I have copied the console error message, but could not figure out how to solve
this. Can you please help me. Thanks.

From your experience, have you came across on performing pen-test in an Oracle
Application that uses jinitiator. Can this software work. Please let me know.
Thanks for your help.

Just would like to add in more. This software works on paros. I was able to
attach the process in JavaSnoop. But not working in Oracle Apps kind of web
applications.
Please share your ideas. I really need it urgently. Thanks again.

I experienced this same issue when attempting to attach to a Java Web Start
based app under Windows 7 Professional 32bit using Java 1.6.0_24. I double
checked the java policy settings that the startup.bat file sets and it all
looked fine. But I was starting the java app via Firefox 4, and when I switched
to starting the app via IE9 I was able to attach javasnoop successfully. I
haven't had a chance to investigate any differences in the way the browsers
invoke java differently but for thse havin this problem with applets or web
start etc. this might be a quick fix if it works for others too.

It seems the reason that I was getting this error was due to the fact that
script.bat file was trying to place the java.policy file in c:\documents and
settings\<unmae> however the real file needed to be placed in "C:\Documents and
Settings\<uname>\Application Data\Sun\Java\Deployment\security" on my machine.
When I took the unsafe.policy file from resources/unsafe.policy and placed it
in that folder and renamed it to java.policy I stopped getting that error.
Please use the README.txt file in Javasnoop and figure out how ti turn the
console on for java apps. That tells you if you have any security exception. If
you see that then most likely what I did should solve your issue. I did this on
Windows XP/SP3.

Thanks for the solution Mandar.
I modified my batch file line as follows and tested it and it resolve the
issue. Perhaps this change should be implemented into the source Arshan? Note
there were two things that needed to be fixed. 1) the location itself and 2)
Windows needs quotes around a full path like this.
-set user_policy=%USERPROFILE%\.java.policy
+set user_policy="%USERPROFILE%\Application
Data\Sun\Java\Deployment\security\java.policy"
I also commented out the second to last line which copies the safe user policy
into place. I didn't have a policy by default and I don't know enough about
Java security policies to be comfortable changing it.
Thanks for your work on this Arshan!

I should have mentioned this was with 1.0. It doesn't look like I was getting
the same error with 1.1RC1, but the java.policy file wasn't successfully
copying either using the default batch file. I'm pretty sure you at least need
quotes around any path that contains a drive letter. I'm on XP by the way.
May not be different in W7.

Some of this is copy+pasted from a previous post but this is a new bug report
as far as I know.
I am also experiencing the error message:
"Could not initialize agent: Agent JAR loaded but failed to initialize"
What steps will reproduce the problem?
1. Press button "Attach & Snoop Process..."
2. Choose Java process in the list
3. Press button "Attach" (Attach and clobber lookandfeel also results in the
same)
What is the expected output? What do you see instead?
Status "SNOOPING". JavaSnoop error: "Could not initialize agent: Agent JAR
loaded but agent failed to initialize"
What version of the product are you using? On what operating system?

I think this may have to do with the JVM arguments using JRE and not JDK, but I
can't find any information on how to modify that behavior.

Change the %USERPROFILE%\.java.policy file to reflect the contents of the
resource\unsafe.policy file supplied with the JavaSnoop installation to fix
this issue. Remember, that all instances of the JVM must be closed and
restarted for this to take effect (e.g., if you have a browser window with an
applet started before you changed the policy file, the new policy will not be
reflected to that applet).

I am also getting this problem. I have changed all my java.policy files to the
unsafe one, and I am also providing the -Djava.security.policy attribute to the
browser so I can specifically point at a java policy file. I can list the ePIDS
of all running java apps then it fails on attaching with the same error. I only
get this problem on applets by the way, works fine on fat clients.

I am also getting this problem on a Windows 7 machine. It is with a JavaFX
app. I have used procmon to check to see what policy files it is
loading/reading and have made sure that all of the policy files it touches have
been modified to the unsafe version.

This looks like a problem with the latest version of jdk 1.7. I removed 1.7
and installed the last version of 1.6 and JavaSnoop worked.
