How to get names of method parameters ?

How to get names of method parameters (Not only their type and value) is it only possible during debugging ??
for example void myFunction(int a,int b)
I need the "a" , and the "b" The issiue is about the java.lang.reflect.InvocationHandler ,
and its method invoke(Object proxy,
Method method,
Object[] args)
throws Throwable
I Have the parameter objects themself and their types using method.getParameters() , this is fine ,, but i need the names of the parameters !!!

If the class file was compiled without debug information included then it is impossible to get the original parameter names, as used in the source code.
However, If the class file does include debug information, then the method names are hidden deep within the class file. You'd need to parse the class file yourself. Check out a copy of the Java VM Specification for a detailed format of the java class file format.
It's not a trivial task to parse the java class file, and the VM spec isn't easy reading. You'd nearly be writing a class file disassembler.

Hi Jose,
Thanks for your help, could you please look into my requirement.
For all inspection characteristics listed in the selected COA profile, I have to retrieve the Inspection Method for all listed inspection characteristics. And also I have to retrieve the characteristic value(uncertainty). Additionally, for inspection characteristics that are quantitative, being checked, the characteristic value(uncertainty) from that Inspection method will be retrieved from class 3050_UNCERTAINTY, class type 006, characteristic, P2150_UNCERTAINTY.

How to get name of sbRIO programatically

How to get "name" and "Comment" of sbRIO which I write to sbRIO-9602 in MAX in Identification box (Model, Serial number, MAC address, Name)?
Solved!
Go to Solution.

That shows:
- IP settings
- IP adress:   136...etc.
  - DNS name:   MyMaster5 - THAT IS WHAT I NEED, just in wrong place - in MAX it is not in IP settings, that's why i didn't searched for it there.
  - subnet mask 255.255.255.0
  - gateway 136...
  - DNS server 136...
- MAC address 00800...
- serial number 16....
- system state Running
- model name sbRIO-9602
- model code 7373
- password protected restarts? T/F
- halt if TCP/IP fails? T/F
- locked?   T/F
- use DHCP? T/F
Still there is no "comment" as in MAX. But that's not so important now.
I have LW Development system 2009 SP1 Profesional, Realtime Development 2009 SP1
Thanks very much!

How to get name of table from front end

Hi,
How to get name of table from front end in EBS 11i?
thanx
Ashish

Hi
Sandeep is correct. The "Help"/"Record History" will give you the table/view name, but sometimes this particular menu function give me a "Record History is not available here." error message.
I then use the following menu functions (this will also give you additional information, like column details).
1) Open Forms
2) Click on Help/Diagnostics/Examine (*you might have to enter the APPS password at this point)
3) Change "Block" to "System"
4) Change "Field" to "Last_query"
The system will populate the "Value" field with the query that was executed in order to populate the form.

How to get names of INCLUDE or FORM within included forms

Hello,
I want to get names of Include program and included form within included forms.
I tried SY-REPID or SY-CPROG but these two SYST variables return the name of report program that performs the form, not the name of Include or form.
Please give me any advice about how to get names of include / included form.
thanks and regards,
Hozy

You can use the statement
READ REPORT <Report name> into itab
to read the source code into an internal table.
Later you can use the "Contains Pattern" operator to get the statements that you need.

Can WLW display the real names of method parameters, not arg0, arg1...

Hello
I am new to Java development and as I used to work with MS.NET usually rely on parameter names, so that I don't have to read documentations each time I use a method. However I noticed that WLW replaces the names of method parameters with arg0, arg1, arg2 etc. Is there a way to somehow make WLW display the real argument names and not those argX strings?
Thanks in advance.

<compiler.library-path dir="${FLEX_HOME}\frameworks"
append="true">
<include name="libs" />
<include name="../bundles/{locale}" />

Try -dump-config compiler argument, which will write all the
currently set configuration values. Please find more details at the

How to get the publish method with server side actionscript?

We publish this way at client side:
ns.publish(name, howToPublish);
How to get this howToPublish at server side?
application.onPublish = function(){
//how to know whether the stream's publishing method(live,record,append) here?

I am not sure whether you can know mode of publish via SSAS, best way would be to use Authorisation Plug-in which can intercept you publish request and get the information which you need - in this case mode of publishing.

How to get names of all Windows in a Form Application at runtime

Dear All,
I want to get the name of all windows in a form module programatically at run time. How to get it?
Any help or comments will be highly appreciated.
Thanks in Advance.

Hi Francois Degrelle,
First of all thanks for the response.
What if I have no items on a content canvas? In my application, I am using content canvas to hold the Image banner and help text of the current form, having no items at all. I am also using tab canvases to hold all items of form. The tabs are displayed on the content canvas at run time. So the tab canvases acts like frames (In my case).
Now if I am looping through items, it gives me the list of all of the tab canvases. Whereas the tab canvas always has no window assigned, as it is displayed on content canvas which has that Window which I need. Thus I am unable to get the names of windows in my case through the above stated procedure.
Another option could be if I can get the name of the content canvas upon which the given tab canvas is displayed?
Any way to do this or some other way to achieve the use case?
Any help will be highly appreciated.
Thanks in advance
Bilal

How to get the page request parameters in Command Button code

Hi everyone,
I am new to JSF and working on some Command Buttons. I put my java code via Edit Event, it works fine. But I don't know how to get some parameters from HttpServletRequest.
Can anyone give some guidance? It would be much appreciated.
Mike

Thanks a lot for your tip. Unfortunately I could not open the link you provided due to some network issue.
Yes, I intend to get some parameters from URL. I did try to put your code and get the parameters predefined in the URL, however I got the null returned. By the way, I put the following code in the page source part and it works. Just don't know how to get the value being passed to the command button event code.
<%
String userID = request.getParameter("u");
System.out.println("this is from head - the userID is :: " + userID);
%>
Thanks again and hope you could give me further advice.

How to get name of an entry?

I search in my schema with code below:
List<OrganizationPojo> organizationPojoList = new ArrayList<OrganizationPojo>();
     DirContext ctx = null;
     try {
     // get a handle to an Initial DirContext
     ctx = new InitialDirContext(env);
     String[] attrIDs = { "dc", "objectClass","ou" };
     SearchControls ctls = new SearchControls();
     ctls.setReturningAttributes(attrIDs);
     ctls.setSearchScope(SearchControls.SUBTREE_SCOPE);
     String filter = "(&(dc=*) (objectClass=organizationalUnit) (ou=*))";
     NamingEnumeration answer = ctx.search(searchBaseDn, filter, ctls);
     try
               while (answer.hasMore())
                         SearchResult sr = (SearchResult) answer.next();
                         LdapName dn = new LdapName((String)sr.getNameInNamespace());
                         LdapName rdn = new LdapName((String)sr.getName());
I learned SearchResult.getName returns the name "relative to search base"
But i only want to get the name of entry.
I am getting dn correctly but can not find out how to get rdn relative to parent in the tree.

More generally, to get the RDN of any search result, you're nearly there:
List<Rdn> rdns = new LdapName(sr.geNameInNamespace()).getRdns();
Rdn rdn = rdns.get(rdns.size()-1);

How to get name or unix id of last switched System Events process?

Hello
I am writing a script to be used as an idle function to send a command to a process as soon as it's not frontmost anymore. So far, I can figure how to get the unix id or name of the frontmost process, but not of the previous process . Here is what I have:
on idle {}
my handleProcesses()
return 5 --- '5' tells idle () to run every 5 seconds.
end idle
on handleProcesses()
tell application "System Events"
set FrontApp to (get name of every process whose frontmost is true)
set PrevApp to (get name of previous process)
end tell
--- my command here, like tell PrevApp to hide...
end handleProcesses
My problem is that "previous process" is not in the System Events dictionary. I cannot use "frontmost if false" either, because this would return all other opened applications, not just the previous one.
I know one partial solution would be to use Command-Tab, get the name of frontmost, and use Command-tab again. But, it's not really pratical nor elegant.
What I need is a function which can get my frontmost process name (which is easy), and return it when the process is inactive (no more frontmost).
Thanks.
Vic

You can do what you want if you maintain a record yourself of what used to be frontmost:
tell application "System Events"
set FrontApp to (get name of every process whose frontmost is true)
set lastFrontApp to FrontApp
repeat while FrontApp = lastFrontApp
set FrontApp to (get name of every process whose frontmost is true)
end repeat
set BackApps to (get name of every process whose frontmost is not true)
if lastFrontApp is in BackApps then
--the app is open in the background
else
--the app was closed
end if
end tell
