Calling a CGI pgm From Java

I am calling a CGI program From Java using URL class and I am passing a pdf file under post process. The Content I am appending by Base64 encoding, the CGI program will decode it and print the content
When I send this Content the content is correpting. When CGI program is decoding it is not getting expected content. But the CGI program is working fine If I send that encoded content in a text file.
When I send the encoded content in a text file as attachment OR put in a common drive, the CGI program is working fine. Only I am facing problems when I send this content via post process using URL class.
Why it is happening like this? Is anybody can help me to Resolve this problem?

Just a guess: are you sure the content-type header is correct?

Problem while Calling a CGI pgm From Java with code sample

Hey guys,
I am calling a CGI program from java servlet, while calling cgi program I am passing encoded(Base64) content via post process,
My problem is the encoded data is not posted as expected, the encoded data is corrupting. But when I send encoded data in a text file, cgi program is perfectly decoding and working fine.
Here I am doing Base64 encoding as per requirement, I cannot avoid this encoding.
My doubt is about OutputStreamWriter constructor argument , In OutputStream Constructor I am passing one argument is OutputStream object and another argument is encoding type. I tried with ASCII, US-ASCII & UTF-8 .
My code is as follows, please help me to resolve this issue.
URL url = new URL("CGI server path");
URLConnection urlConnection = url.openConnection();
urlConnection.setDoOutput(true);
OutputStream os = urlConnection.getOutputStream();
BufferedOutputStream buffer = new BufferedOutputStream(os);
OutputStreamWriter writer = new
OutputStreamWriter(buffer, "US-ASCII");
writer.write(encodedPDF-Content);
writer.write("\r\n");
writer.flush();
writer.close();
here encodedPDF-Content is String and it's size is 9565 bytes

Whenever you read something in java into string (with Reader implementation) it expects source to contain text in encoding you specified. It then decodes it and makes 16 bit unicode string from it. Whenever you store string using Writers it does reverse operation with specified encoding (may be different than this which you used to read source) and stores text as a sequence of bytes made of 16 bit unicode string. So, passing text back and forth between programs with the help of files or I/O you can make mistake at both reading and writing encoding. Check for it.
Now, when C programm or other application reads file it may take another assumptions about encoding or may even completly ignore it and read source as a binary file. Then, if you have a source text as a file and have to pass it to other application never do it using Reader/Writer. User raw InputStream/OutputStream instead what will preserve all information unchanged.
here encodedPDF-Content is String and it's size is 9565 byteHow id you get this info? String.length() gets you how many chars is in it, it will be half the number of bytes. If you see your input file beeing 9565 bytes long, see my above statements.

How can i call a CGI script from java?

The subject pretty much says it all. I want to call a perl cgi script so i can read from/write to files on a server. I don't know how to sign applets and this would be the easiest way for me, if someone could please tell me.

Let me get this clear. Basically what u want to do is to just call a URL, right?
U can do it by using the following code:
import java.applet.*;
import java.net.*;
import java.io.*;
public class testhttp
public static void main(String[] args)
try
URL url = new URL ("http://../testcgi.cfm");
HttpURLConnection cxn =
(HttpURLConnection)url.openConnection();
cxn.setRequestMethod("POST");
cxn.setUseCaches(false);
cxn.setDoOutput(true);
cxn.setDoInput(true);
ByteArrayOutputStream bytes = new
ByteArrayOutputStream(400);
PrintWriter writer = new PrintWriter (bytes,true);
writer.print("application=map&release=1&items=prog1");
writer.flush();
cxn.setRequestProperty("Content-
Length",String.valueOf(bytes.size()));
cxn.setRequestProperty("Content-
Type","application/x-www-form-urlencoded");
bytes.writeTo(cxn.getOutputStream());
System.out.println(bytes);
String currentLine;
BufferedReader in = new BufferedReader (new
InputStreamReader(cxn.getInputStream(),"8859_1"));
while((currentLine = in.readLine()) != null) {
System.out.println(currentLine); }
catch(Exception e) { e.printStackTrace(); }
There is also a library called HTTP client which can be found at:
http://www.innovation.ch/java/HTTPClient/index.html
It's very simple to use and the documentation is all there, but their web server seems to be down right now.
Anyway, hope my post helps.

Calling a Web Service from Java

Our java guru (who is out sick....AHHHH) created all the calls that are needed to access the web service that he has running. For example the call getLongList(String user, String password) will return a list of all outstanding transactions. He made a jar file that has service has class files for PortType, Service, Service Locator and Soap Binding stub.
How do I call this web service from java? Do I have to import it into my classpath? or just call these parameters from within my java code?

never mind...i got it

Calling a Web Service from Java Webdynpro

SBK

Hi SBK,
I assume you may already have read the [help guide|http://help.sap.com/saphelp_nw70/helpdata/EN/81/12703e5da3e946e10000000a114084/content.htm] This gives a pretty good idea of how to do it (step by step).
Is there a typo in the error you pasted?
Error The method setRouteGeometryLineArray(double][) in the type Trip is not applicable for the arguments (double[]) ComplexType_Trip.java WS_INVOKE/gen_wdp/packages/com/cintas/test/model/p1 line 249
The square brackets [] after double in the method call appear to be reversed. Is that also in the code? or just a mistake here?
Hope this points you in the right direction.
BRgds,
Simon

Calling packaged stored procedure from Java

Hi All,
I'm trying to call a stored procedure from Java but I'm having
problems with registrating the output parameter. I'm getting
the error: Conflicting parameters.: sqltype=2003
This is the stored procedure which is located in a package in
the Oracle database:
package Pack_GetAgencyInformation as
Type InfoType is record ( agen_code varchar(3), agen_designation
varchar(30), agen_adresse varchar(60), agen_tel varchar(12) );
function GetAgencyInformation( P_AGENCE VARCHAR )
return Pack_GetAgencyInformation.InfoType
end Pack_GetAgencyInformation;
This is the Java source from where I'm calling the procedure:
//DriverManager.registerDriver (new
oracle.jdbc.driver.OracleDriver());
     Class.forName("oracle.jdbc.driver.OracleDriver");
Connection conn = DriverManager.getConnection
("jdbc:oracle:thin:@164.48.69.125:1521:ventes", "system", "*****
// @machineName:port:SID,
userid, password
CallableStatement cs = conn.prepareCall("{ ? = call
Pack_GetAgencyInformation.GetAgencyInformation( ? )}");
     try {
          cs.registerOutParameter( 1,
oracle.jdbc.driver.OracleTypes.ARRAY);
     } catch (SQLException e) {
          e.printStackTrace();
     cs.setString(2, "001" );
     //ResultSet rset = cs.executeQuery();
The stacktrace:
java.sql.SQLException: Parametertypen conflicteren.:
sqlType=2003
at oracle.jdbc.dbaccess.DBError.throwSqlException
(DBError.java:168)
at oracle.jdbc.dbaccess.DBError.throwSqlException
(DBError.java:210)

(OracleCallableStatement.java:220)
at
oracle.jdbc.driver.OracleCallableStatement.registerOutParameter
(OracleCallableStatement.java:350)
at dbAccess.main(dbAccess.java:25)
I think it has to do with the type InfoType which is created in
the Stored Procedure. I'm absolute no Oracle expert and I
prefer not to make changes to the Oracle database. So any
solution in Java is welcome!
BR, H.Rietman

I managed to get it to work only by changing the stored
procedure. I have changed the return type record to a Ref
Cursor type (had to change alot of code for this). It seams
that Oracle JDBC drivers DON'T support the Record type as a
return type.
So the next question is: is it possible to typecast a record
type to a ref cursor type in Oracle. In this way I can easily
change the return type for the stored procedures.

On making call to Oracle procedures from Java, Value becomes null on oracle

We are using some user defined Oracle data types in my Java/J2EE application
and some of them are Oracle collections(ex. VARRAY).
We are making a call to Procedures/Functions from Java, there are some
parameters of user defined data types declared in the
procedures/functions, from java the values are properly setting to these
user defined data type parameters and sending to Procedures.
We are not getting any exception at Java side and Oracle side and values
are becoming blank/null at oracle procedure side for the parameters of
user defined data types.
But when do the count of collection of user defined data type then it is
properly giving the size of collection(VARRAY).
When we are trying to read the values from the collection(VARRAY) it is
giving blank/null value and there is no exception.
Please let me know if you have any suggestion on this?

user7671994 wrote:

How do I call a C++ program from Java?

I've tried using Runtime.exec to call my C++ program from Java but I don't think I'm doing it correctly. Could someone explain how to properly use it? Here's what I'm trying (this is in an applet that is only going to be running on an intranet so only PCs in my LAN will be affected):
Runtime runtime=runtime.getRuntime();
Process proc =runtime.exec("mkdir C:\\Test");

What do you expect your operating system should do with a command "mkdir"? It doesn't understand this. "mkdir" is a shell command, so you need to execute the shell:
runtime.exec("cmd /c mkdir C:\\test");

How to Call abap functn/program from java layer

Hi all,
I have to develop a program which has to call abap function/program from java side or how to call a abap program through java ..
pls send me related links or explanations.. dont send unrelated answers..
Regards,
Arivarasu S

Hi,
You mean accessing ABAP functions from J2EE perspective, then I think we can do this by using SAP Java Resource Adapter and also through webservices.
SAP Java Resource Adapter (SAP JRA) can be used as an add-on for the SAP JCo SAP JRA enables the implementation of standard interfaces from diverse J2EE servers to the SAP JCo in the SAP Web AS. The SAP JRA thus simplifies
communication with ABAP within heterogeneous J2EE landscapes.
Go through the following links which has Good documentation on how to achieve this

Calling MS Access queries from Java

Anyone have any idea if it's possible to call MS Access queries from Java? I have a client who is insistent on keeping MS Access for their database, and it'd be nice if I didn't have to receate all their queries in Java.
I've successfully connected to and queried the Access MDB, but I need to know if it's even possible to execute the stored MS Access queries they have setup in the database.
Thanks!
