How to pass a HTTP request from a simple java class

Is it possible to pass an HTTP request from a simple java class.if yes how?

Is it possible to pass an HTTP request from a simple
java class.if yes how?If you're talking about creating a HttpRequest object and passing it to a servlet, that would be a red flag to me that your design is flawed. You shouldn't have to do that - the application server (Tomcat, Weblogic, etc) should be the only thing that has to worry about creating that kind of object and passing it to you.

How to create resized image instance from an existing image

It looks like the image class does not provide a possibility to create a resized instance. Image#impl_getURL() would be good enough to create a resized instance of an existing image - but could be removed in a future release. So what's the preferred way if I have an image object only - there's no information about the based image resource.

You can resize an image on loading using one of the constructors that takes requestedWidth and requestedHeight parameters. This is useful for preserving memory when (for example) needing to display a large number of thumbnails.
Additionally, the ImageView class defines resizing functionality for the view of an Image. So you can load the full Image, then display one or more resized versions in ImageView(s).
If you need, you can retrieve an Image object representing the ImageView by calling snapshot(...) on the ImageView; for most use cases the ImageView itself will be all you need.

Creating a Web Service From an existing Java Project

Hi folks,
I'm new to web services and SAP Netweaver so I need to know if I can use my exisiting Java codes (not EJB's though) for creating web services and the WSDL. I've already gotten the codes working and all and just need to make them into web services and deploy them (plus give my WSDL).
I've noticed in some samples that they used EJB's for creating new web services and I've been trying to find samples/steps on just creating webservices from exisitng java codes. I've been using AXIS but I've been told that creating web services using the Netweaver Developer Studio is rather easy.
Thanks in advance!

Hi Amol!
Thanks for the link
I was trying it out, but could you see if this was correct:
I just made one simple java project (with one class file) and using the link you sent me and did just the step for using the web service Creation Wizard. I made it say Test service and got into the Web Services Explorer but it says it couldn't open my wsdl:
IWAB0379E Unable to open http://localhost:50000/HelloBeanService/HelloBean?wsdl.
IWAB0135E An unexpected error has occurred.
WSDLException
WSDLException: faultCode=OTHER_ERROR: http://localhost:50000/HelloBeanService/HelloBean?wsdl
Did I miss a step?
Thanks again!

Is it possible to get the Source from the Compiled Java Class File?

Hello All,
I wrote a java file which uses Java Swing to crea a GUI.I have also compiled the jave file.
The problem now is that i've made many changes and compiled it many times.Now suddenly due to some problem,the contents of tha Java file have been deleted and it shows 0 bytes.
Is there any way to recover my Java source file from the Class file?I would be thankful to anyone who can help me out on this.
Thanks in Advance,
Regards,
Vijayakannan

Yes and no, you can reverse engineer it to an extent, it wont look exactly like your original source though, it'll be full of commented out bytecode bits etc. As its your own code though you've got the best chance of deciphering it. Go to somewhere like www.tucows.com to download the software for doing it.

How do create an analog signal from a text or binary file?

I'm trying to output an analog signal from a file on an NI-DAQ 6251 card using labview 8.5. I've found the examples on building a waveform, but I'm stuck at how to read a text file and make a 1-D array to input my amplitudes into the buildwaveform.vi and I can't find any information on how to do so. Any help or direction is greatly appreciated.
thanks,
David
Solved!
Go to Solution.

If all that you want in the file is the Y values, then a text file with a value on each line could be read. The Read From Spreadsheet File can be used. It will return a 2D that you can then use the index array function to get a column or if you select Transpose, the returned 1D array would be used.
If you want to create an example, use a 1D array constant in a VI and pass it to the Write to Spreadsheet File.

How to create the database schema from an existing TimesTen database ?

Hello everybody,
I'm a newbie to TimesTen database. Before doing complicated sql queries, I would like to obtain the database schema of TimesTen DB. I'm looking for a way to extract the schema of database (tables, keys, links between tables ...). When I was working on other db like postgreSQL, I was able to obtain the sql script of the database (for exemple, in order to re-create the database in an other server). Some software like PowerAMC was able to built the database model from these scripts.
Do you know a way to obtain the same with TimesTen database ? Or with an other way ?
Regards

Hi,
Take a look in the docs at ttSchema, this might do the trick.

@jasonwryan
Thank you, i was not aware of that builtin. At first i wanted to use this in combination with "grep --after-context=XX" and then i realized that i can use it this way:
mapfile -s XX -t configs </etc; echo "${configs[@]}"
Thank you very much.

If you are using MSSQL SERVER then try creating a stored procedure like this
create proc Name
select * from Table
by executing this in sql query analyzer will create a stored procedure that returns all the data from Table
here is the syntax to create SP
Syntax
CREATE PROC [ EDURE ] procedure_name [ ; number ]
    [ { @parameter data_type }
        [ VARYING ] [ = default ] [ OUTPUT ]
    ] [ ,...n ]
[ WITH
    { RECOMPILE | ENCRYPTION | RECOMPILE , ENCRYPTION } ]
[ FOR REPLICATION ]
AS sql_statement [ ...n ]
Now Create new report and create new connection to your database and select stored procedure and add it to the report that shows all the columns and you can place the required fields in the report and refresh the report.

How to create a new connection from SAPGUI to Test drive?

Hi,
I have installed Sap Netweaver Test drive on a linux virtual machine (windows host). The installation was successful and I was able to start the instance (application server and the database), yet I don't know how to create a new connection from my SAPGUI client (7.20) to this server. The static IP address of the server is 192.168.1.160.
I entered the following values for my new connection entry
Description: SAP Netweaver
Application server: 192.168.1.160
Instance number: 01
System ID: DB2
SAProuter: /H/192.168.1.160/S/3201/H/
But it does not work. Any idea about the values needed for creating a new entry?
Thanks in advance,
Dariyoosh

Hello there,
Thank you very much for your answer which solved my problem. In fact there was no need of providing router string.

How to create an XML document from a String.

Can anyone help,
     In the Microsoft XML Document DOM there is a load function load(string) which will create an XML document, but now we are switching to Java and I do not know how to create and XML document from a string, this string �xml document� is passed to my program from a webservice and I need to read several xml elements form it in a web server.
This string is a well formatted XML document:
<?xml version="1.0" encoding="UTF-8"?>
<Countries NumberOfRecords="1" LanguageID="en-us">
     <Country>
          <CountryCode>AU</CountryCode>
          <CountryName>AUSTRALIA</CountryName>
     </Country>
</Countries>

Thanks PC!
I made it work using:
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
DocumentBuilder builder = factory.newDocumentBuilder();
factory.setIgnoringComments(true); // We want to ignore comments
// Now use the factory to create a DOM parser
DocumentBuilder parser = factory.newDocumentBuilder();
//TransformThisStringBuffer is a string buffer wich contain the 'XML document (String)'
InputStream in = new ByteArrayInputStream(TransformThisStringBuffer.toString().getBytes());
// Parse the InputStream and build the document
Document document = parser.parse(in);
But which one is faster InputSource or InputStream, were would you put the "new InputSource(new StringReader(yourString))" in the above code?

In Acrobat 11 you'd select: Tools > Forms > Edit
