Calling a javamethod from asp

hi,
i've tried for days, not getting this to work.
I have written a java class as an IIS Extension, placed it in %winhome%/java/trustlib and called several methods. If a method only returns a string it all works, but when connecting to my database through my javaclass I get a NullPointer Exception.
ASP code: Please note that the asp connection to the database works. using odbc.
<body>
<%set sc = GetObject("java:CSSupplier")
'Response.Write(sc.getAline()) <--- this returns a string and works
set DBConn = Server.CreateObject("ADODB.Connection")DBConn.Open "DSN=chunkstore;UID=chunkyBoy;PWD=********"
sql = "SELECT * FROM supplier"
set rs_supp = Server.CreateObject("ADODB.RecordSet")
rs_supp.Open sql,DBConn
While Not rs_supp.Eof
Response.Write rs_supp("name") & " "
rs_supp.MoveNextWend'The above code works and lists results.%></body>I've tried to use a method sc.getSupplierInfo() but it returns a nullpointer exception.
public java.sql.Connection getConnection() {
try {
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver").newInstance();
java.sql.Connection conn = null;
conn = DriverManager.getConnection("jdbc:odbc:chunkstore", db_username, db_password); }}
public ResultSet getSupplierInfo() {
Connection conn = null;
Statement stmt = null;
ResultSet rs = null;
String sql = "SELECT * FROM supplier";
/*if (supplier_id > 0) { sql += " WHERE supplier_id = " + supplier_id; }*/
try {
conn = this.getConnection();
stmt = conn.createStatement();
rs = stmt.executeQuery(sql); }
catch (SQLException e) { //throw new SQLException(e.getMessage()); }
finally {
try {
if (conn != null) {
conn.close();
conn = null; } }
catch (SQLException e) { //throw new SQLException(e.getMessage()); } }
return rs; }It seems like the database is not accessed at all, there are two records in the table, and it works from pure ASP (ado).
How should a resultset be called and placed in an ADO.RecordSet?
What may the error be in this code?
Thanks for all help!

i get this errormessage:
sun/jdbc/odbc/JdbcOdbcDriver
try {
     Class.forName("sun.jdbc.odbc.JdbcOdbcDriver").newInstance(); // tried without the new instance also
     String url = "jdbc:odbc:chunkstore"; //members is my data source
     Connection con = DriverManager.getConnection(url,"",""); // tried with username and password too
     Statement stmt = con.createStatement();
     rs = stmt.executeQuery(sql);
     if (rs.next() == true) {
       answ = rs.getString("name"); //column name is IC
    catch (Exception e) {
      //throw new SQLException(e.getMessage());
      return "Feil1: " + e.getMessage() + ", conn:"+conn+",sql:"+sql+"rs:"+rs;

How to call a function from asp

Hi!, I'd like to know how to call a function from an asp page. I've written:
set rs = server.createobject("Adodb.recordset")
rs.open "call dbo.sf_Obt_Des_Producto ('0000161')",Conn
if err.description <> "" then
response.write ("No se pudo! :(")
else
response.write ("rs: " & rs(0))
end if
rs.close
set rs = nothing
but there is an error:
ORA-06576: not a valid function or procedure name
Please is very urgent!!!
Thanks.
Angie.

You need to use the syntax "{call <procedure_name>}".
The {call } syntax tells the OLE DB provider that it needs to translate the call into whatever the database's procedure calling syntax is. This means that even though different databases have different syntax for calling stored procedures, your OLE DB code can be run against any of them without changing.

1 - Can I clear errors on the OraDatabase class. How do
I do that?They store the last error, should clear itself.
2. Is this a client side or server side error? If this
is a client side error, how do I resolve it?Server side error only. Make sure the user you connect as can see 'RATELINK_CAPACITY_CONTROL.CC_INSERT' and has execute permissions on it. You may need to qualify it with a schema name if the connected user is not the schema owner.

Call Oracle Function from ASP++++!

I have a lot of Oracle function in packages and i would like use it in my ASP pages.
With Oracle procedure it's all right.
Sample like this
set cn = Server.CreateObject("ADODB.Connection")
connString = "Provider=MSDAORA.1;Data Source=<>;User ID=<>;Password=<>"
cn.Open connString
SQL = "{call test.test_asp({resultset 0, cResult})}"
Set cmd = Server.CreateObject ("ADODB.Command")
Set cmd.ActiveConnection = cn
cmd.CommandText = SQL
cmd.CommandType = 1 'adCmdText
Set rs = Server.CreateObject ("ADODB.RecordSet")
Set rs = cmd.Execute
If NOT (rs.BOF and rs.EOF) Then
Do while NOT rs.EOF
<%=rs("dfcountry")%>
<%=rs("dfname")%>
rs.MoveNext
LOOP
End if
And in package TEST i have
PROCEDURE TEST_ASP(cResult IN OUT ResultCursor)
IS
BEGIN
OPEN cResult FOR
SELECT *
FROM tcountry;
END TEST_ASP;"
I Hope You help me with similar call a function!!!
For example, this is one
FUNCTION test_fun
RETURN resultcursor
IS
vres resultcursor;
BEGIN
OPEN vres FOR
SELECT *
FROM tcountry;
RETURN vres;
END test_fun;

Stored Procedures
When executing an Oracle PL/SQL stored procedure using a command, use Oracle native syntax or the ODBC procedure call escape sequence in the command text:
Oracle native syntax: BEGIN credit_account(123, 40); END;
ODBC syntax: {CALL credit_account(123, 40)}
Preparing Commands
OraOLEDB validates and fetches the metadata only for SELECT SQL statements.
Command Parameters
When using Oracle ANSI SQL, parameters in the command text are preceded by a colon. In ODBC SQL, parameters are indicated by a question mark ("?").
OraOLEDB supports input, output, and input/output parameters for PL/SQL stored procedures and stored functions. OraOLEDB supports input parameters for SQL statements.

Calling LabView from ASP or PHP ?

Hi;
I was wondering if someone could help me.
I need to control a spectrum analyzer remotely.. The VI's are ready, and I would Like to call/Run them from ASP/PHP in order to enable the remote client to interact with the VI's via a normal Web Browser.
Tips:
client should be able to send the VI's some data(variables).
Get the results back and display it on the web page.
Kind Regards
K.S.
Student

In that case, you might want to check http://www.jeffreytravis.com/. He has a book called "Internet Applications in LabVIEW". The book was written before 6.0 introduced remote panels. There's also an application there available for download called LabVNC that might work for you. I haven't tried it but it sounds like it would do the trick.

How to change Crystal Reports XI database name at run time from ASP code using ADO

Dear All,
I need advises regarding to my problem below
I have two database in same SQL 2005 SERVER for TEST01 and LIVE01 Environtment, and I've created more than 100 reports with Crystal Reports 11 and call it from ASP classic page.
The problem is how can I change a database from TEST01 to LIVE01 at the run time from ASP code as I already using TEST01 database on Crystal Reports and I do not want to set a new database location inside crystal for each reports
Thanks and wait for your reply soon.
Below is my code, which has no effect to crystal reports although I've change the database from TEST01 to LIVE01:
<%
Dim oADOConnection, oRptTable, oADORecordset, sql
Dim struser, strpwd, strdriver, dblocation, dbname, strConnect
struser = "sa"
strpwd = ""
strdriver = "{SQL SERVER}"
dblocation = "SQL200501"
dbname = "LIVE01" ' Changed from TEST01 to LIVE01
strConnect = "User Id=" & strUser & ";"
strConnect = strConnect & "PWD=" & strPwd & ";"
strConnect = strConnect & "DRIVER=" & StrDriver & ";"
strConnect = strConnect & "SERVER=" & DBLocation & ";"
strConnect = strConnect & "DATABASE=" & dbName
sql="Select * from Employee"
Set session("oApp") = Server.CreateObject("CrystalRuntime.Application.11")
Set session("oRpt") = session("oApp").OpenReport("C:\REPORTS\RPT01.RPT", 1) 'USING TEST01 DATABASE
session("oRpt").MorePrintEngineErrorMessages = False
session("oRpt").EnableParameterPrompting = False
session("oRpt").DiscardSavedData
Set oADOConnection = Server.CreateObject("ADODB.Connection")
oADOConnection.Open (strConnect)
Set oADORecordset = Server.CreateObject("ADODB.Recordset")
Set oRptTable = session("oRpt").Database.Tables.Item(1)
oRptTable.SetDataSource oADORecordset, 3
session("oRpt").SQLQueryString = CStr(sql)
session("oRpt").ReadRecords
%>

Did you ever find a solution to this problem? I have the same problem when moving reports from development to Test to Production environments. If the DBName is not the same the report ignores the name provided at runtime.

Error while calling a form from another form's menu item

I created a main form and menu module for this form.
I am calling another form from main form menu item.
i moved both the forms and menu and compiled them.
But, when i run this form i am getting an error saying
FRM 92100: Your connection to the server was interrupted
This may be the result of a network error, or a failure on the server.
You will need to establish your session.
I set the seperateframe = true
networkentries = 30
But still getting the same error.
Is there any parameter that i am missing.
I will greatly appreciate if anybody can direct me to the solution.
Thank you.

Error while calling a procedure from ESB

Hi,
I am calling a procedure from ESB using DB adapter. and in the routing rules i am mapping the i/p values for schema to procedure input variables using mappings(transformation) but the values are going as null to the procedure call.
Please help me out.
The exception follows...
An unhandled exception has been thrown in the ESB system. The exception reported is: "org.collaxa.thirdparty.apache.wsif.WSIFException: esb:///ESB_Projects/ESB-Issues_issue3/db3.wsdl [ db3_ptt::db3(InputParameters,OutputParameters) ] - WSIF JCA Execute of operation 'db3' failed due to: Error while trying to prepare and execute an API.

[Caused by: ORA-01400: cannot insert NULL into ("SYSTEM"."ISSUES"."ISSUE_NAME")

This is likely being caused by a problem that we've seen a number of times. You'll have namespace issues and problems with NULLs if your JDev is 10.1.3.1 and SOA is 10.1.3.3 (or vice-versa). You MUST synchronize JDev 10.1.3.3 (or higher) with SOA 10.1.3.3 (or higher). It doesn't matter if you mix 10.1.3.3 and 10.1.3.4. You just need to get away from 10.1.3.1.
