Reading JavaDoc from Code

If I have a folder structure with .java files in it, and I want to point JavaDoc at it and have it tell me JavaDoc info, how do I do that? One way is to extend Doclet, but then I can only call it from the command line with javadoc -doclet ... However, what if I just want to do it from ordinary code?

Looks like you found a solution. Here are a couple of belated answers, passed along from an engineer...
Do you know how my Doclet class could communicate with the rest of the program?The easiest (not really clean) might be to just create a singleton for
communication, which is shared by all instances of the doclet, and
whatever other point in the program care about it.
Does anyone know how Eclipse or Netbeans reads and displays the Javadoc info when you
import a library? Do you think they just have their own parsers, or do they do it through
the javadoc api?Eclipse has its own parsers. Netbeans uses javac. - Hey, Netbeans
comes from Sun, you'd expect that.

Is ti possible to read JavaDocs from an application ?

Hi all,
I have inserted inside Javadocs information which are useful for unit testing.
Java source code can be read and parsed with standard i/o Api but I wonder if it's possible to use JavaDocs tool programmatically.
For example how to read for example the variable "service" ?
* @service=service1
*/Any suggestion ? thanks
Francesco

Hi,
That "variable" you have inserted looks like a tag. Exactly the tag will be this (without '='):/*
* @service service1
*/The "service" is the tag name and "service1" is the tag content.
Javadoc offers lots of stuff to process tags (including, the user defined ones). The ultimate thing, I believe, is Doclet API that provides all the information Javadoc uses itself, including any tags specified within comments.

Unable to read data from Analog Devices 6b11 module - error code 1240

Hi everyone,
I'm trying to read data from a thermocouple with an AD 6B11 module in an AD 6BP16-1 backplane using RS232 serial. I've been following this guide:
http://digital.ni.com/public.nsf/allkb/8C77E5E52B4A27968625611600559421
Everything seems to work out well until step 13, where I call the "AD6B Input Module - Read Data.VI". I get an error code 1240 stating something like "invalid parameter or unable to read instrument".
Has anyone got any experience with this error or suggestions to fixing it?
Thanks in advance!

That user guide is 20+ years old. The serial functions from that day used 0 for com 1, 1 for com 2, etc. Make sure you have the correct one selected. Please provide the exact error message instead of 'something like'.

ABAP Code to Read Characteristic from Another DSO

Gurus and Experts,
Plain and simple, I need a piece of ABAP code that reads a characteristic value from a different DSO.
Here is the story. I have a data flow from DSO Delivery1 to DSO Delivery2. I need to write a code in the start routine of the transformation to read Sales_Doc_Type from DSO Sales1. The condition is, if Delivery1-Ref_Doc_Nr = Sales1-Sales_Nr then Delivery1-Sales_Doc_Type = Sales1_Sales_Doc_Type.
I am a beginner in SAP BI and know nothing about ABAP. But I do have experience in SQL and Java.
Any help or links or direction will be appriciated. Thanks in advance.
Herru

Hello,
I think there is a correction in your Ques. That there are two DSO Delivery1 and Sales1...... I Hope this is Ok.
Tables Required:---- Go To SE11 and *<DSO_NAME>00 You will get active table for your DSO. EG. /bic/Delivary100 and /bic/sales100
Logic In start Riutine:----
1. Define structure in Global Def. for Sales1 DSO.
2. Also Define Internal table in Global Def. (I hope you know the syntax)
3. now you will find that start writing code from below.
Inclue:------ Select Statement from Slaes1 DSO into itab for all entries in source package.
4. Loop source_package assigning <result_fields>.
read itab into wa where Sales1-Sales_Nr = <result_fields>-Ref_Doc_Nr.
<result_fields>-Sales_Doc_Type = wa-Sales1_Sales_Doc_Type.
endloop.
This logic will work..........
If still you are find it difficult then take some abaper help.

Ankit.

Modify javadoc source code

Hello :-)
I would like to use javadoc to read comments inside the methods, but i know there is no such thing in javadoc now so i am thinking either to implement this feature myself or find other documentation generators to use. Does anyone has any good ideas on how to do it???
Have anyone done such thing already? I know i can get javadoc source code from tools.jar, butt confused on how to modify it and build it or making the jar on that... Thanks a lot....

Javadoc from JAR package.

Hello
Suppose that I have a JAR package and do not have the source files. Is it possible to generate Javadoc from the JAR?
Thanks.

Not without some additional work. The Javadoc tool requries source code to work, so you'd first have to reverse engineer the JAR to get source code from it. And even then, it may not include comments, so the resulting Javadocs would be pretty lame. But at least they'd include class names, method signatures, etc. Better than nothing.

Reading items from a list view in SharePoint 2013

I am trying to read items from a Calendar, and have created a view that contains all the items/events that I would like to retrieve to package in a CSV file, specifically the Title, Description, and the Start and End Dates.
The problem with some events is that they are recurring, and rather than use CAML to expand the events and try to query it that way, I thought it would be more elegant to just get the events from the view, and package them with a simpler query.
The problem I am running in to is that I can reference the entire list and package the data, or I can reference the list and get all the data in a specific date range, which does not include the recurring events, but I cannot simply read the data from the
view.
Any pointers would be greatly appreciated. Also, can you recommend any complete-ish texts on PowerShell with SharePoint?

Hi,
Based on my understanding, as there is no straight way of using CAML to query all the events(specially for instances of recurring events) by a list view, I would suggest
you separately query the instances of recurring events needed.

how to query events(include recurring events) from Calendar list in this thread for your reference:

Read data from a Stored Procedure in Android

I have a Stored Procedure say CustOrdersDetail. I have created a MBO for it in the workspace and deployed it on SAP Mobile Server. I am unable to read data from the stored procedure in code of the Android Application. If I pass a default load argument, then I am able to read data using findAll method. How to get the data from the stored procedure by passing it an argument in the Android Code ?
Message was edited by: Abhijit Kadam

Currently I am trying to call the stored procedure and retrieve the results. The stored procedure accepts 'orderId' as an argument and fetches the Product and Order Details.

TcpListener not working on Azure: Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host

Hi Everybody,
i'm playing a little bit with Windows Azure and I'm blocked with a really simple issue (or maybe not).
I've created a Cloud Service containing one simple Worker Role. I've configured an EndPoint in the WorkerRole configuration, which allows Input connections via tcp on port 10100.
Here the ServiceDefinition.csdef file content:
<?xml version="1.0" encoding="utf-8"?>
<ServiceDefinition name="EmacCloudService" xmlns="http://schemas.microsoft.com/ServiceHosting/2008/10/ServiceDefinition" schemaVersion="2014-01.2.3">
<WorkerRole name="TcpListenerWorkerRole" vmsize="Small">
<Imports>
<Import moduleName="Diagnostics" />
<Import moduleName="RemoteAccess" />
<Import moduleName="RemoteForwarder" />
</Imports>
<Endpoints>
<InputEndpoint name="Endpoint1" protocol="tcp" port="10100" />
</Endpoints>
</WorkerRole>
</ServiceDefinition>
This WorkerRole is just creating a TcpListener object listening to the configured port (using the RoleEnvironment instance) and waits for an incoming connection. It receives a message and returns a hardcoded message (see code snippet below).
namespace TcpListenerWorkerRole
using System;
using System.Net;
using Microsoft.WindowsAzure.ServiceRuntime;
using System.Net.Sockets;
using System.Text;
using Roche.Emac.Infrastructure;
using System.IO;
using System.Threading.Tasks;
using Microsoft.WindowsAzure.Diagnostics;
using System.Linq;
public class WorkerRole : RoleEntryPoint
public override void Run()
// This is a sample worker implementation. Replace with your logic.
LoggingProvider.Logger.Info("TcpListenerWorkerRole entry point called");
TcpListener listener = null;
try
listener = new TcpListener(RoleEnvironment.CurrentRoleInstance.InstanceEndpoints["Endpoint1"].IPEndpoint);
listener.ExclusiveAddressUse = false;
listener.Start();
LoggingProvider.Logger.Info(string.Format("TcpListener started at '{0}:{1}'", RoleEnvironment.CurrentRoleInstance.InstanceEndpoints["Endpoint1"].IPEndpoint.Address, RoleEnvironment.CurrentRoleInstance.InstanceEndpoints["Endpoint1"].IPEndpoint.Port));
catch (SocketException ex)
LoggingProvider.Logger.Exception("Unexpected exception while creating the TcpListener", ex);
return;
while (true)
Task.Run(async () =>
TcpClient client = await listener.AcceptTcpClientAsync();
LoggingProvider.Logger.Info(string.Format("Client connected. Address='{0}'", client.Client.RemoteEndPoint.ToString()));
NetworkStream networkStream = client.GetStream();
StreamReader reader = new StreamReader(networkStream);
StreamWriter writer = new StreamWriter(networkStream);
writer.AutoFlush = true;
string input = string.Empty;
while (true)
try
char[] receivedChars = new char[client.ReceiveBufferSize];
LoggingProvider.Logger.Info("Buffer size: " + client.ReceiveBufferSize);
int readedChars = reader.Read(receivedChars, 0, client.ReceiveBufferSize);
char[] validChars = new char[readedChars];
Array.ConstrainedCopy(receivedChars, 0, validChars, 0, readedChars);
input = new string(validChars);
LoggingProvider.Logger.Info("This is what the host sent to you: " + input+". Readed chars=" + readedChars);
try
string orderResultFormat = Encoding.ASCII.GetString(Encoding.ASCII.GetBytes("\xB")) + @"MSH|^~\&|Instrument|Laboratory|LIS|LIS Facility|20120427123212+0100||ORL^O34^ORL_O34| 11|P|2.5.1||||||UNICODE UTF-8|||LAB-28^IHE" + Environment.NewLine + "MSA|AA|10" + Environment.NewLine + @"PID|||patientId||""""||19700101|M" + Environment.NewLine + "SPM|1|sampleId&ROCHE||ORH^^HL70487|||||||P^^HL70369" + Environment.NewLine + "SAC|||sampleId" + Environment.NewLine + "ORC|OK|orderId|||SC||||20120427123212" + Encoding.ASCII.GetString(Encoding.ASCII.GetBytes("\x1c\x0d"));
writer.Write(orderResultFormat);
catch (Exception e)
LoggingProvider.Logger.Exception("Unexpected exception while writting the response", e);
client.Close();
break;
catch (Exception ex)
LoggingProvider.Logger.Exception("Unexpected exception while Reading the request", ex);
client.Close();
break;
}).Wait();
public override bool OnStart()
// Set the maximum number of concurrent connections
ServicePointManager.DefaultConnectionLimit = 12;
DiagnosticMonitor.Start("Microsoft.WindowsAzure.Plugins.Diagnostics.ConnectionString");
RoleEnvironment.Changing += RoleEnvironment_Changing;
return base.OnStart();
private void RoleEnvironment_Changing(object sender, RoleEnvironmentChangingEventArgs e)
// If a configuration setting is changing
LoggingProvider.Logger.Info("RoleEnvironment is changing....");
if (e.Changes.Any(change => change is RoleEnvironmentConfigurationSettingChange))
// Set e.Cancel to true to restart this role instance
e.Cancel = true;
As you can see, nothing special is being done. I've used the RoleEnvironment.CurrentRoleInstance.InstanceEndpoints to retrieve the current IPEndpoint.
Running the Cloud Service in the Windows Azure Compute Emulator everything works fine, but when I deploy it in Azure, then I receive the following Exception:
2014-08-06 14:55:23,816 [Role Start Thread] INFO EMAC Log - TcpListenerWorkerRole entry point called

I've already tried to configure an internal port in the ServiceDefinition.csdef file, but I get the same exception there.
As you can see, the client can connect to the service (the log shows the message: Client connected with the address) but when it tries to read the bytes from the stream, it throws the exception.
For me it seems like Azure is preventing the retrieval of the message. I've tried to disable the Firewall in the VM in Azure and the same continues happening.
I'm using Windows Azure SDK 2.3
Any help will be very very welcome!
Thanks in advance!

hi Javier,
I changed your code like this:
private AutoResetEvent connectionWaitHandle = new AutoResetEvent(false);
public override void Run()
TcpListener listener = null;
try
listener = new TcpListener(
RoleEnvironment.CurrentRoleInstance.InstanceEndpoints["Endpoint"].IPEndpoint);
listener.ExclusiveAddressUse = false;
listener.Start();
catch (SocketException se)
return;
while (true)
IAsyncResult result = listener.BeginAcceptTcpClient(HandleAsyncConnection, listener);
connectionWaitHandle.WaitOne();
The HandleAsync method is your "While (true)" code:
private void HandleAsyncConnection(IAsyncResult result)
TcpListener listener = (TcpListener)result.AsyncState;
TcpClient client = listener.EndAcceptTcpClient(result);
connectionWaitHandle.Set();
NetworkStream netStream = client.GetStream();
StreamReader reader = new StreamReader(netStream);
StreamWriter writer = new StreamWriter(netStream);
writer.AutoFlush = true;
string input = string.Empty;
try
char[] receivedChars = new char[client.ReceiveBufferSize];
// LoggingProvider.Logger.Info("Buffer size: " + client.ReceiveBufferSize);
int readedChars = reader.Read(receivedChars, 0, client.ReceiveBufferSize);
char[] validChars = new char[readedChars];
Array.ConstrainedCopy(receivedChars, 0, validChars, 0, readedChars);
input = new string(validChars);
// LoggingProvider.Logger.Info("This is what the host sent to you: " + input + ". Readed chars=" + readedChars);
try
string orderResultFormat = Encoding.ASCII.GetString(Encoding.ASCII.GetBytes("\xB")) + @"MSH|^~\&|Instrument|Laboratory|LIS|LIS Facility|20120427123212+0100||ORL^O34^ORL_O34| 11|P|2.5.1||||||UNICODE UTF-8|||LAB-28^IHE" + Environment.NewLine + "MSA|AA|10" + Environment.NewLine + @"PID|||patientId||""""||19700101|M" + Environment.NewLine + "SPM|1|sampleId&ROCHE||ORH^^HL70487|||||||P^^HL70369" + Environment.NewLine + "SAC|||sampleId" + Environment.NewLine + "ORC|OK|orderId|||SC||||20120427123212" + Encoding.ASCII.GetString(Encoding.ASCII.GetBytes("\x1c\x0d"));
writer.Write(orderResultFormat);
catch (Exception e)
// LoggingProvider.Logger.Exception("Unexpected exception while writting the response", e);
client.Close();

Reading values from ServletRequst in Filter

I have a filter that captures some basic info (request method and uri) from request. But whenever I read parameters contained in http request for "POST" method, I can't figure out how to repost parameters to request. I think that after I read parameters from request in filter, parameters aren't available in http servlet. I think that I have to repost parameters to request after i read it.
does anybody know how to do it?

here is the code.
     BufferedReader in = new BufferedReader( new InputStreamReader (request.getInputStream()));
     String line = null;
     while (null != (line = in.readLine()))
          System.out.println(line);
After I use request.getInputStream(), I can't retrieve values from parameters. is there any way to handle this issue?
I'd appreciated for any idea.

Reading values from standard report in custom report dynamically

Hello Gurus,
I have a strange requirement, We have some standard reports which displays output in drop down blocked data. I want to create a custom report which will get that data in my internal tables.
Just to elaborate this requirement, I will give you a example:
I have a standard report which output as first line 'A' and second line as 'B'. Now when I press drop down in 'A', it displays line items say 1,2,3,4,5.... Similarly block 'B' once when pressed displays line items 6,7,8,9,10.
Here I want a custom report which directly read data from this standard report and gives us the values of line items 1,2,3,4,5 in one internal table and similarly items 6,7,8,9,10 in another internal table.
Hope the question clarifies the requirement now.
Request you to please provide the resolution.
Thanks,
Harjeet

Hi Harjeet,
Use sumit statement for standard program and export the list to memory. and then read list from memory and use in your custom program.
Use below code for reference.

How to read parameters from request object

We want to read parameters from GET request
but whenever we are calling GET_URI_PARAMETER from the REQUEST we don't see any results
url is like
http://coevi116.wdf.sap.corp:8000/sap(bD1lbiZjPTEwMA==)/bc/bsp/sap/z_test_json/jsontest.htm?PARAM=ABC
But reading PARAM is not givng value of ABC
onCreate and onRequest wherever we put the code it is not reading the value
Can anyone please help and share some expert opinion

in jsontest.htm page create a page attribute named "PARAM" with auto check box checked and check in oninitialization, this will carry the value passed to param from url.
