How can i invoke an Oracle Report w/in a Java application?

I have a custom java application that I would like to integrate with a report tool. I am reviewing Oracle Reports but I was not sure how I would integrate an Oracle Report.
I have read that I can use Active-X but. Has anyone ever done this? Also - is there any support for a java bean?
I am also wondering how I could pass in report parameters.
It is my understanding that Oracle will generate either pdf or html output which could be viewed through the browser or adobe acrobat reader.
Is this correct?
Please advise.
Thanks in advance.

Bonnie,
I create a URL that calls Oracle Reports Server running under IAS, using PDF or html as the output. The Java code calls up the commandline and starts the default browser with the specified URL, which then talks to Oracle Reports Server... and voila... the report shows up in your browser!
have fun...
void execURL ( String pURL )
System.out.println(pURL);
if (System.getProperty("os.name").equals("Windows NT") )
try
Runtime.getRuntime().exec("cmd /c start "+pURL);
catch (Exception e1) {System.out.println(e1.getMessage()); }
else
try
Runtime.getRuntime().exec("start "+pURL);

Problem with socket connection through Java Embedding...

We are trying to create a simple socket connection to a socket server through BPEL PM using the Java Embedding component.
BPEL Process : Client makes an asynchronous request. Passes an input variable. The input variable is sent to the Server Program through a socket connection through the Java embedding component.
Server: We are running a simple Socket Server program from command prompt.
The code below works fine as long as we do not try to receive a response from the server (Commented Code).
If we uncomment the code and try to receive a response, it refuses to create an instance for the BPEL Process. And sometimes restarts the BPEL Server.
Client Code:
String msg="NONE";
try{
org.w3c.dom.Element input = (org.w3c.dom.Element) getVariableData("inputVariable","payload","/client:clientProcessRequest/client:input");
msg = input.getNodeValue();
Socket clientsoc=new Socket("ServerIP",1000);
PrintWriter out1=new PrintWriter(clientsoc.getOutputStream());
out1.write(msg);
out1.flush();
BufferedReader cin1=new BufferedReader(new InputStreamReader(clientsoc.getInputStream()));
msg=cin1.readLine();
setVariableData("outputVariable","payload","/client:result",new String(msg));
clientsoc.close();
catch(UnknownHostException e)
System.err.println("Don't know about host: dev.");
System.exit(1);
catch (IOException e)
System.err.println("Couldn't get I/O for "+ "the connection to: dev.");
System.exit(1);

How to get Formatted Mail Content through Java Application

I am using a mail sending function in my applet code which is listed below:
Main content is fetched from a format tool bar in JSP Page and it is passed as parameter to applet and it is used inside the mail content.
Same content when passed and executed in a JSP page, the formatted content is not lost and it is included in mail content as what it is fetched from Format Tool Bar.
Format is lost when it is used inside the Java Application mail sending function.
The below code I have used to send mail:
package com;

Unicode characters in the mail content are replaced by ?.
In the function listed above I have used the MIME Setting as
Multipart multipart = new MimeMultipart("alternative");
I have tried by using relative MIME format also as
Multipart multipart = new MimeMultipart("relative");
But I am not getting the actual format passed as input to the Java Application in the mail content.
Can anybody let us know how to overcome this problem?
Thanks in advance.

You need to really understand how the different multiparts work instead of just guessing.
But for your application, you don't need a multipart at all. Just use msg.setText(msgText, null, "html");
Although that doesn't explain your problem, it will simplify your program.
How are you determining that the mail received doesn't have the formatting? Are you viewing it in a
mail reader (e.g., Outlook)? Or are you fetching it with JavaMail?
Are you using an Exchange server? Exchange will often reformat your message to what it thinks you meant.

Cannot Create Datasource through Java Application

Hi All,
I tried to create a datasource through my Java application
JDBCDescriptor jdbcDescriptor = new JDBCDescriptor();
 jdbcDescriptor.setDataSourceName("ds_venky");
 jdbcDescriptor.setDriverClassName("org.gjt.mm.mysql.Driver");
 jdbcDescriptor.setDriverName("mysql");
 jdbcDescriptor.setInitConnections(2);
 jdbcDescriptor.setMaxConnections(10);
 jdbcDescriptor.setPassword("xxxx");
 jdbcDescriptor.setURL("jdbc:mysql://172.22.76.8:3306/wise");
 jdbcDescriptor.setUsername("xxxx");
Properties ctxProp = new Properties();
 ctxProp.put(
 Context.INITIAL_CONTEXT_FACTORY,
 "com.sap.engine.services.jndi.InitialContextFactoryImpl");
 ctxProp.put(Context.PROVIDER_URL, "myServerName:50004");
 ctxProp.put(Context.SECURITY_PRINCIPAL, "xxxx");
 ctxProp.put(Context.SECURITY_CREDENTIALS, "xxxx");
 InitialContext context = new InitialContext(ctxProp);
 DataSourceManager dsm =
 (DataSourceManager) context.lookup("dbpool");
 dsm.createDataSource("ds_venky", jdbcDescriptor);
But i get the following exception

If you were expecting the spool file to be translated to ASCII with carriage returns, line feeds, and form feeds, here is the magical piece of code:
SpooledFile splf = new SpooledFile(sys, splfName, splfNum, jobName, jobUser, jobNum);
PrintParameterList pl = new PrintParameterList();
pl.setParameter(SpooledFile.ATTR_MFGTYPE, "*WSCST");
pl.setParameter(SpooledFile.ATTR_WORKSTATION_CUST_OBJECT, "/QSYS.LIB/QWPDEFAULT.WSCST");
InputStream in = splf.getTransformedInputStream(pl);
For reasons not immediately clear to me, the first character in the file appears to be a null byte (hex 0). I also believe that CRs and LFs only appear as needed to return to the beginning of the line (CR) and the feed one line (LF). It is permissible for example to have <data><CR><LF><LF><LF> (i.e. feed three lines). I also assume that <data><CR><data><CR><LF> would result in overprinting (missing line feed). I have even seen <data><CR><CR>, and I assume the second CR should be ignored.
I have not exhaustively tested these scenarios, but from some of the problems we've had, the above description seems like a reasonable way to think about the data stream

How to call function in included dll file through java application.

Hi All,
i am trying to create an java application which call c# functions using JNI. i am completed with the code and it is running fine when i tried to run from netbeans IDE. But when i tried from Calculator.jar file, first time it throws this error:
F:\JavaProjects\Calculator\dist>Java -jar Calculator.jar
Exception in thread "main" java.lang.UnsatisfiedLinkError: no CSharpClient in java.library.path
at java.lang.ClassLoader.loadLibrary(Unknown Source)
at java.lang.Runtime.loadLibrary0(Unknown Source)
at java.lang.System.loadLibrary(Unknown Source)
at calculator.CalculatorApp.<clinit>(CalculatorApp.java:20)
After that i included that dll file in the cuurent directory. And compiled and tried to run, it throws an unexpected error:
F:\JavaProjects\Calculator\dist>Java -jar Calculator.jar
*# An unexpected error has been detected by Java Runtime Environment:*
*# Internal Error (0xe0434f4d), pid=2640, tid=3700*
*# Java VM: Java HotSpot(TM) Client VM (1.6.0_02-b06 mixed mode, sharing)*
*# Problematic frame:*
*# C [kernel32.dll+0x12a5b]*
*# An error report file with more information is saved as hs_err_pid2640.log*
*# If you would like to submit a bug report, please visit:*
*# http://java.sun.com/webapps/bugreport/crash.jsp*
Anyone have idea how to solve this error.
Thanks in advance.

This error is created whenever things go sour on the native side. The first thing you can try, and I assume you are using a Java<->C++<->C# bridge which includes two dlls, one created by C++ and another by C#. Is to make sure that the C# dll is compiled using /t:module switch during compilation.
If you are using VS2008, or VS2005, you can add a post build syntax like:
csc /t:module /out:"$(ProjectDir)$(OutDir)YourModule.dll" "$(ProjectDir)YourCSfile.cs"
Hope this helps! If not, ensure first that the native code works by creating a native test app for it.

RFC connectivity through JAVA

Hello sir,
I have create 1 java class file which connects to SAP DB through RFC connection.
I have put sapjco3.dll,librfc32.dll,sapjcorfc.dll in to the folder windows\system32.
Its working fine on windowsXP, but not working on Windows Vista and windows server 2003.
its giving error as
java.lang.UnsatisfiedLinkError: D:\splerp3\sapjco3.dll: The application has failed to start because
its side-by-side configuration is incorrect.
please tell me what configuration i have to do for vista and server 2003.

Hi guys,
please pay attention to the given infos on the JCo download site. It says:
Note: Starting with JCo 2.1.4 and JCo 2.0.11, JCo requires the Visual Studio .NET C/C++ runtime libraries on Windows platforms.
Starting with JCo 3.0.0, it requires the Visual Studio 2005 C/C++ runtime libraries. See SAP note [684106|https://service.sap.com/sap/support/notes/684106] for details on how to install them.
Installing the VC redistributable packages from Microsoft will solve this issue.

Stefan

Connecting through java to HSQLDB: Out of Memory

Well The issue was somewhere else due to it reading too much of data. It ran but my program is very slow (approx 2-3 hrs).
I am worried about the speed...
is it because of the large amount of data.. 23,355,459 records..?? or there could be some issue in programming probably memory leak etc..??
-> reads db
-> for each record set
-> perform different operation/ writes to file

How I can connect my java application to unix server

I want to develop simple desktop Application using which I can login and fire simple UNIX command like ls -lrt etc. Can any one guide me to achieve this ?

Here is a sample program which illustrates connecting to a unix server using SSH protocol.
The API used is enchanter - http://code.google.com/p/enchanter/
import java.io.IOException;
import org.twdata.enchanter.SSH;
import org.twdata.enchanter.impl.DefaultSSH;
public class MainSSH {
 * @param args
 * @throws IOException
 public static void main(String[] args) throws IOException {
 SSH ssh = new DefaultSSH();
 ssh.connect("<IP_Address>", 22<port_number>, "<user_name>", "<password>");
 ssh.waitFor("]$");
 ssh.sendLine("ls -lrt");
 System.out.println(ssh.getLine());
 ssh.disconnect();
}Thanks,

Mainframe connection through java

Hi,
Is it possible to connect to a mainframe and retrieve the results from it i.e., the data stored are in the form of cards(record types).Is it possible to connect to such set up using JDBC connectivity as we do for the normal RDBMS connection..
Kindly help me in this regards
Wiht thanks in advance
subra

Why on earth should a "mainframe" (you even didn't tell us which OS) be such a magic zone that even Java can't enter it?
How do other programming languages manage to connnect to a DBMS on a mainframe?
How has for example Oracle succeeded to be used on mainframes?
I think you should ask your DBMS' vendor at first.
"Mainframe" is a collective name for certain hardware structures only.

You put the machine name as the host name. I would put the (internal) network address of the laptop there and try again - and make sure that Oracle is actually listening on your internal network address in stead of only the localhost. Or are you running the java application on the same laptop? Then you can simply use 'localhost' as the host name.
