I am trying to create a Jlink script and I was wondering, what is the syntax or there is a call equivalent to invoke JLINKARM_JTAG_StoreInst ?
Above function is available via JLINK DLL but I am unable to call it within the Jlink script itself, any ideas on how to overcome this?
Thanks!

I have came across a situation where I have to call a jar with a string parameter and get the result. Is there any way i can able to do this? I came across a link where importing java:java.lang.Math namespace using Java function inside XQuery. This will help me to use library functions of Java. Is there any way I can call jar or customize function from XQuery?
MarkLogic doesn't have a way to directly call a Java method in a JAR file. The common practice is to have the required Java functionality available as a service, then call that from MarkLogic. For instance, you could set up Tomcat to host the functionality that lives in the JAR file.
I am trying to compile SQLite into a library which another application is then going to link against. I am not able to compile SQLite directly into that application for reasons which are beyond the scope of this question.
However, I need a VFS to be available which by default is not. In trying to figure out how to get this working I am trying to get the vfstrace shim to be made available to the application which is linking to SQLite. This will easily prove that it is working as I can log SQLite VFS activity from the shim and see that it is actually being used when the application calls SQLite.
How do I do this? All the examples I have found show the case of when you have a source file (such as shell.c) and you compile it, sqlite3.c and test_vfstrace.c to produce an executable. However, I do not have this luxury. I could compile sqlite.c and test_vfstrace.c and generate the libsqlite3.so library file, but there is no "main" function in which to call vfstrace_register so that the VFS is actually available. Is there some other hook for the library case where I can set this up? If no, how do I make a new VFS available?
SQLite is initialized via the sqlite3_initialize() function, which is called automatically when various functions such as sqlite3_open() are called by the user, although it is a no-op on subsequent invocations. This function in turn calls the OS specific initialization function sqlite3_os_init(). This is the function that initializes all the VFSes that are built into SQLite.
For the example VFS given, append test_vfstrace.c to the amalgamation and then put a call like this in sqlite3_os_init() right before the return statement:
vfstrace_register("trace",0,(int(*)(const char*,void*))fputs,stderr,1);
Then build the library with these modifications.
The last parameter's value of 1 will make this VFS be the default, so if you don't want trace messages printed for every SQLite operation performed via code linked the library you just created change this to 0 and explicitly specify this VFS when opening a database to trace the calls for. For instance, specify the SQLITE_USE_URI compile time option, and then pass a filename of the form: "file:database.db?vfs=unix" where "database.db" is the actual name of the file to open.
As we know, there are two methods of library loading.
1) Static libraries (.a): Library of object code which is linked with, and becomes part of the application.
2) Dynamically linked shared object libraries (.so), which will link at execution of application and it can be used in two ways.
a) Dynamically linked at run time but statically aware.
b) Dynamically loaded/unloaded and linked during execution (i.e. browser plug-in) using the dynamic linking loader system functions.
After compilation, we can check the library dependency of type 'a' as below
objdump -x usr/bin/flashcp
.....
Dynamic Section:
NEEDED libgcc_s.so.1
NEEDED libc.so.6
My question is how to check/detect type 'b' library dependency ? Please suggest is there any way to detect before execution ?
Thanks in advance

There's no way to generally check for libraries that are loaded dynamically and whose functions are called via function pointers.
In some special cases, as a hack, you can attempt various ways of reverse-engineering the executable, e.g. statically analyzing code around the calls to LoadLibrary and GetProcAddress on Windows. You could derive some heuristics that would work on many executables, but there's no way that's guaranteed to work, other than executing the code in a virtual machine and intercepting all calls to LoadLibrary/dlopen as they happen.
i wrote a script in javascript and used it in rules (share). The script start with:
var ctx = Packages.org.springframework.web.context.ContextLoader.getCurrentWebApplicationContext();
I m getting an error telling me that "Reference error: Packages is not defined".
How can i solve this issue?
The Packages object is only available for code which is considered "secure". This is most likely failing because the code is from a node in the Repository/Data-Dictionary. Put it somewhere in the classpath (e.g. classes/alfresco/templates/webscripts/...).
I don't think you can use this object in javascript, you won't find that code anywhere in Share javascript files. According to this link, Package root scope object is only available for web script implementations placed into the Java classpath, due to security reasons.
Try writing Java code for your rule.
I'm trying the sample demo of selenium flex API. After following the instructions on the main page for compiling the project with sfpi.swc and taking the generated selben.swf in bin directory and trying to run some test(assertFlexText) using Selenium IDE, I get the following error:
[error] Function getFlexText not found on the External Interface for
the flash object selben
I have tried several other flex tests and got error messages similar to the one mentioned above.
For some reason I believe that the generated selben.swf through the automatic build of project in flex builder is not the desired one, though it didn't indicate any build problem after including sfpi.swc.
Any idea?
I use SeleniumFlex Api and SeleniumIde for my projecy with excellent result BUT using my own version of each of one. Your error maybe is for not include the lib of SeleniumFlexApi in the compile time( -include-libraries "libs\SeleniumFlexAPI.swc" ).
After that u can enable capture and replay with SeleniumIde change the main source (read this post) and use the user-extensions.js (in the SeleniumFlexApi project) with the SeleniumIde user option. Its really easy.
With these change u can capture and replay in firefox (v 3.06 or minor) and after that, if u use java, u can use Flex-UI-Selenium, Flash-Selenium for ur integration test with SeleniumRC.
I hope this information be usefull. I u have any question let me know.
