Java ME and asp connectivity

Hello everyone,
I know this is a very repetitive question but i still havent found a satisfying solution anywhere.
Here is the scenario:
I am developing a MIDlet which recieves an Account number as the body of an SMS.
I have a database in MS-Access which stores account numbers and corresponding account balances.
I need to retrieve the balance from the database.
HTTP connection allows the asp functionality on Java ME SDK 3.0 but not when the midlet is installed on my Samsung SGH-X700 phone.
I want the connectivity between the phone and PC through USB cable.
I mean the midlet works on emulators but does not access the files through USB cable
How to access http://localhost/test1.asp (which is on PC) through the cable?
OR can it be done through a CommConnection?Please help.

thanks for the reply Prakash.
So, i'm using websphere with JCO to connect Bw.
Actually, i encountered the same return message in my java code and during the se37 transaction.
In se37 transaction:
I call the Bapi BAPI_MDDATASET_CREATE_OBJET
I set manually an mdx command generated with MDXTEST
on my BW query.
this BAPI return a DATASETID
the persistence of the object is ok.
after that, if i use the bapi BAPI_MDDATASET_CHECK_SYNTAX
or BAPI_MDDATASET_SELECT_DATA with this DATASETID...
I have always the same error as return message.
RS_EXCEPTION : CL_RSR_MDX_COMMAND========CP
the problem is coming from the DATASETID?
Thanks,
best regards,

Problem with Java Proxy and Socket Connection

Hi Gurus!!
I have developed a Java Proxy that connects via socket with a Server Socket application. This Server Socket application accepts more than one connection at the same time.
When I connect the first time from my Java Proxy, the connection is correctly established. When the first connection opened, if a try a second connection, this is not established.
I use "new Socket(SocketServer,SocketPort);" to open the connection.
I think that all time the Java Proxy is trying to open the same connection, and this is a problem.
Is there a way to indicate to the server that is a new connection and that the existing connections remain?
Anybody could help me, please?
Thanks and regards,
Manuel Míguez.

Server Issue with Oracle and ASP Connection

We got a new server and are trying to set it up with Oracle Client to allow our web application to connect to the database server. We are getting connection errors, but on the old server, it works fine. We have Windows 2003 and IIS 6.0 on the new server and Win2K and IIS 5.0 on the old server and it's Oracle 8i. Here is the error...
Err.description=Oracle client and networking components were not found. These components are supplied by Oracle Corporation and are part of the Oracle Version 7.3.3 or later client software installation. Provider is unable to function until these components are installed.
Err.number=-2147467259
... We have the client installed, so not sure what to do from this point on. Can it be some type of a sharing issue, or network firewall issue?

Have you granted the IIS user read & execute access to the %ORACLE_HOME% directory and subdirectories?

Urgent help(xml, java and asp)

Hi all,
I,m new with XML and i have to convert a VB application that connects to an ASP using Microsoft XML and I need to know if I can connect from a java application to an ASP using XML for transfering the infornation.
In the ASP side it uses DOM, and I would like not to touch the ASP and create a new application with java and get rid of the VB application

What I need to do is to change the VB part for a Java application and basicly, I don't know what Class of Java I have to use to connect to the ASP.
If you were so kind of giving me an example to do this I will appreciate it.

WebDynpro java and Oracle Connection

Hi,
I'm trying to make a simple connection to an Oracle database within a custom webdynpro component. Using NWDS 7.0.08 and EP 7.0 SP 10.
Here is a sample of the java code I use :
Connection conn = null;
Class.forName("oracle.jdbc.driver.OracleDriver");
DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
conn =DriverManager.getConnection ("jdbc:oracle:thin:@hostname:port:DATABASENAME","schema", "password");
Statement stmt=conn.createStatement();
ResultSet rs=stmt.executeQuery("select * from MYTABLE");
But when I run this WebDynpro, the following error appears :
"oracle.jdbc.driver.OracleDriver".
I have also catched the exception stack but it doesn't seem meaningful. If you need it, I can provide it in another thread.
So What should I do to connect to this oracle database ? Is it the right provider ?
Thanks,
Loïc LEVEUGLE

Hi!,
please try following code, this is working fine for me.
String serverName = "172.21.1.62";
String portNumber = "1526";
String sid = "vision";
String url = "jdbc:oracle:thin:@" + serverName + ":" + portNumber + ":" + sid;
String userName = "scott";
String password = "tiger";
Connection connection = null;
try {
    // Load the JDBC driver
    String driverName = "oracle.jdbc.driver.OracleDriver";
    Class.forName(driverName);
    connection = DriverManager.getConnection(url, userName, password);
    Statement stmt =connection.createStatement();
    PreparedStatement pstmt = connection.prepareStatement("insert into club (Name,EmpID,Location,Extention,MailID,InstPlay) values(?,?,?,?,?,?)");
               pstmt.clearParameters();
    pstmt.setString(1,Name);
    pstmt.setString(2,EmpID);
    pstmt.setString(3,Location);
    pstmt.setString(4,Extention);
    pstmt.setString(5,MailID);
    pstmt.setString(6,Instrument);
    pstmt.executeUpdate();
} catch(Exception exc) {
     exc.printStackTrace();

Settings SLD and JCO connection for Java Web Dynpro

Hi BI Gurus,
I'm a Business Intelligence newbye and I'm a bit confused about Web Dynpro configurations.
I try to execute, through Netweaver Developer Studio 7, a simple java Web Dynpro who call the standard Flight List BAPI.
My configuration is: NW 2004s installed on BI server (with java instance and j2EE Server) and Flight List BAPI stored on R/3 ECC. 5 System in another server.
Now, my doubt are:
1) in SLD Data Supplier (J2EE Visual Admin on BI Server) CIM configuration, what are the connections parameter necessary?The BI host or R/3 host?
2)if I set BW system parameters in SLD and in NWDS when I try to run my simple web dynpro an error occour This is the output:
The initial exception that caused the request to fail, was:
com.sap.tc.webdynpro.services.exceptions.WDRuntimeException: Failed to resolve JCO destination name 'WD_FLIGHTLIST_RFC_METADATA_DEST' in the SLD. No such JCO destination is defined in the SLD.
Correction Hints
Accessing the System Landsape Directory (SLD) failed. Depending on the concrete reason (see root cause) check the following:
is the SLD Supplier in the J2EE engine configured correctly? See the SLD documentation for more details about the SLD and about how to configure it.
are all JCO destinations maintained correctly? Use the preinstalled Web Dynpro Content Admin application to check/edit the destination. Use the Ping and Test functions of the Content Admin to verify that each destination is properly configured.
Additional information about the System Landscape Directory and the Web Dynpro Content Admin can be found in the SAP Developer Network (SDN) and in the Online Help for the SAP Web Application Server (installed with SAP NetWeaver Developer Studio and available online).
Note: the above hints are only a guess. They are automatically derived from the exception that occurred and therefore can't be guaranteed to address the original problem in all cases.
3)where can I create new JCO connections?What are the requirements settings?
I am always available for answers about the post!!
Help me please!!
Thanks thousand and sorry for my incorrect english!!

Andrea,
You can Create the JCo destination from Content Administrator. You must login as Administrator.
use the link as
http://<server>:<port>/webdynpro/welcome/Welcome.jsp, select Content Administator->Create JCo Destinations/Maintain JCo Destinations.
Please have a look on the following links regarding creating/maintaining JCo destinations. The are usally asked questions regarding JCo destinations.

What is the better way to open and close connection in bean

Hello, may i ask about the best way to open and close the connection?
At the first, the connection code is store in Conn class bean. The JSP page will call a method in Process bean to process the query and update of database. the Process bean is using th Conn to connect to database.
In my process bean, it have a method for each type of sql like select, insert, update, and delete for each tables. Each method will call the Conn to open and close the connection. The jsp page can simply call a method retrieve or update records.
However, when calling the processUpdate method, it is a method that update a group of tables base on the query result of another group of tables and calculation. If I calling the query method in the same bean file, it will open and close the connection many times (more than 1000 times). After open and close the connection several times, the connection to mySQL will be fail.
Currently, i include 2 method in Process that is only calling the Conn to open the connection and close connection. When calling the openConnection method, it will also set the boolean connected in the class to true and call Conn to open connection. When calling the closeConnection method, it will also set the boolean connected in the class to false and call Conn to close connection.
After that, i add some change to the query method which is when the connected is false, it will open the connection by calling the Conn and close the connection themself. If the connected is true, it will not call the Conn to open and close the connection because it already connected to the database.
Now, i when i calling the query method in jsp, it can open the connection and close the connection individually. When i call the processUpdate in the jsp, this method will calling the openConnection before calling the query and calling closeConnection at the end. It not only faster the process(less open and close), it also no cause the connect to mySQL fail error again. However, it also make the coding in the bean file more longer and complex.
Is there have any better solution?

Use connection pooling. This will put the connection management in the hands of the webserver, not your code. Check out this post:

Open java app and insert text

Hello All!
I'm looking for a little help on an exact problem that seems to have been solved here before (but doesn't work for me).
Here's the original archived thread:
https://discussions.apple.com/thread/2631967?start=0&tstart=0
The question asked is exactly the same....
I have a java app for a Speco Technologies DVR. After opening the app, you must type in a rather long url and then click connect. If you enter the url, then quit the app, when you relaunch it, it does not remember the url that had been entered the previous time.
I would like to create a script that will launch the Java app and then input the url (text string). I cannot get this to work.
I've gotten as far as this:
on run
tell application "Finder" to activate open document file "DVRVIEWER(DO_NOT_DELETE).jar" of folder "Applications" of startup disk
delay 5
set myString to "192.168.0.118"
repeat with currentCharacter in every character of myString
tell application "system events"
keystroke currentCharacter
end tell
delay 0.25
end repeat
tell application "system events"
keystroke return
end run
AppleScript has a Syntax Error of "Expected end of line, etc. but found command name."
Does anyone ( taylor.henderson where are you! ) have a fix, or even a better way to do this? Can I edit the existing .jar to have the info directly in there?
I would actually love to add another section in there that fills in the username and password after entering in the IP address!
Just for clarification on how this goes:
Launch .jar.
Window Launches and prompts for IP address
Enter in IP address
Press RETURN
Windows disappears and new window appears and prompts for username and password
Enter Username
Press TAB
Enter Password
Press RETURN
Thank you guys, I'm sure it's easy, but hey, for me Photoshop and Illustrator are a breeze :-0

Performance degradation using Jolt ASP Connectivity for TUXEDO

We have a customer that uses Jolt ASP Connectivity for TUXEDO and is suffering
from a severe performance degradation over time.
Initial response times are fine (1 s.), but they tend to increase to 3 minutes
after some time (well, eh, a day or so).
Data:
- TUXEDO 7.1
- Jolt 1.2.1
- Relatively recent rolling patch installed (so no there are probably no JSH performance
issues and memory leaks as fixed in earlier patches)
The ULOG shows that during the night the JSH instances notice a timeout on behalf
of the client connection and do a forced shutdown of the client:
040911.csu013.cs.kadaster.nl!JSH.234333.1.-2: JOLT_CAT:1185: "INFO: Userid:
[ZZ_Webpol], Clientid: [AP_WEBSRV3] timed out due to inactivity"
040911.csu013.cs.kadaster.nl!JSH.234333.1.-2: JOLT_CAT:1198: "WARN: Forced
shutdown of client; user name 'ZZ_Webpol'; client name 'AP_WEBSRV3'"
This happens every 10 minutes as per configuration of the JSL (-T flag).
The customer "solved" the problem for the time being by increasing the connection
pool size on the IIS web server.
However, they didn't find a "smoking gun" - no definite cause for the problem.
So, it is debatable whether their "solution" suffices.
It is my suspicion the problem might be located in the Jolt ASP classes running
on the IIS.
Maybe the connection pool somehow loses connections over time, causing subsequent
users having to queue before they get served (although an exception should be
raised if no connections are available).
However, there's no documentation on the functioning of the connection pool for
Jolt ASP.
My questions:
1) What's the algorithm used for managing connections with Jolt ASP for TUXEDO?
2) If connections are terminated by a JSH, will a new connection be established
from the web server automatically? (this is especially interesting, because the
connection policy can be configured in the JSL CLOPT, but there's no info on how
this should be handled/configured by Jolt ASP connectivity for TUXEDO)

Winfried Scheulderman

Hi,
For ASP connectivity I would suggest looking at the .Net client facility provided in Tuxedo 9.1 and later.

Using java class and variables declared in java file in jsp

hi everyone
i m trying to seperate business logic form web layer. i don't know i am doing in a right way or not.
i wanted to access my own java class and its variables in jsp.
for this i created java file like this
package ris;
import java.sql.*;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;
public class NewClass{
    public static void main(String args[]){
        Connection con = null;
        ResultSet rs=null;
        Statement smt=null;
        try{
            Class.forName("com.mysql.jdbc.Driver").newInstance();
            con=DriverManager.getConnection("jdbc:mysql:///net","root", "anthony111");
            smt=con.createStatement();
           rs= smt.executeQuery("SELECT * FROM emp");
           while(rs.next()){
            String str = rs.getString("Name");
            }catch( Exception e){
                String msg="Exception:"+e.getMessage();
            }finally {
      try {
        if(con != null)
          con.close();
      } catch(SQLException e) {}
}next i created a jsp where i want to access String str defined in java class above.

Very bad approach
1) Think if your table contains more than one NAMEs then you will get only the last one with your code.
2) Your String is declared as local variable in the method.
3) You have not created any object of NewClass nor called the method in JSP page. Then who will call the method to run sql?
4) Your NewClass contains main method which will not work in web application, it's not standalone desktop application so remove main.
Better create an ArrayList and then call the method of NewClass and then store the data into ArrayList and return the ArrayList.
It should look like
{code:java}
package ris;
import java.sql.*;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;
public class NewClass{
    public static ArrayList getNames(){
        Connection con = null;
        ResultSet rs=null;
        Statement smt=null;
        ArrayList nameList = new ArrayList();
        try{

Error in the Socket Communication between Java Client and VC++ Server

In my application, using Java Client to do socket bi-communication with VC++ Server, which is done by somebody else.
The error is after the application properly running one or two days, the VC++ Server cannot receive the messages passed by java Client, but at Java client, everything is the same, although using CheckError() after every print(), there is no exception thrown.
The JVM is jdk1.3.1, platform is Win2k Server.
The outputstream is PrintWriter().
Please help me to settle down this problem. Thanks in advance.

I read some thread in the forum, and found somebody had the similar problem with me. Just want to know how to settle this problem.
In the client/server program. Client is a JAVA program and Server a
VC++ program. The connection works, and the problem appears after some time. The Client sends a lots of requests to Serverm, the server seems receive nothing. But at the same time, the server is able to send messages to Client. The Client also can get the messages and handle them. Don't understand why there this problem and why it appears when it wants.
The client is a Win2k platorm with JDK1.3.1 and the server is also a Win2K platform with VC++ 6.0.
In the Client, using:
inputFromServer = new BufferedReader(new InputStreamReader(socket.getInputStream()));
outputToServer = new PrintWriter(new BufferedWriter(new OutputStreamWriter(socket.getOutputStream())),true);
Hope can get your help.
