Call AS400 RPILE or CLLE from JAVA pgm

Hi is it possible to call an AS400 RPGILE or CLLE from a Java Pgm. And if so does someone have any example code to do so?
Thanks

Maybe your call is wrong... Shouldn't there be a "?" instead of "1"?
Your code:
String myquery = "begin :1 := jspTest; end;";
I provide my (working) call from java as an example. Maybe it is of any help... :)
import java.sql.*;
import oracle.jdbc.driver.*;
public Vector getAllHosts() throws SQLException {
//return getHosts(false, -1);
Connection conn = null;
CallableStatement cs = null;
Vector hostV = new Vector();
try {
conn = getConnection();
String query = "{ ? = call curTestPkg.curTestFunc}";
cs = conn.prepareCall(query);
cs.registerOutParameter(1, OracleTypes.CURSOR);
cs.execute();
ResultSet rs = ((OracleCallableStatement)cs).getCursor(1);
while (rs.next()) {
Host host = new Host(
rs.getInt("hostid")
, rs.getString("name")
, rs.getString("descr")
, rs.getString("os"));
hostV.add(host);
cs.close();
return hostV;
} finally {
close(conn, cs);

hi Stefan thanx.....even after changing the call statement i get the same error. i changed query string as...
String myquery = "{ ? = call jspTest}";
CallableStatement cst = con.prepareCall(myquery);
Can u please check out my call sepc that i have written in pl/sql and plz let me know it there is any error in that.
PS : THIS IS THE FIRST TIME I AM WORKING WITH PL/SQL AND IT IS URGENT

Calling a PL/SQL function from java

I would like to call a pl/sql function from java. My pl/sql function is taking arrays of records as parameters. How do i proceed? Which specific oracle packages do I have to import?
Please send an example.
TIA,

Documentation here: http://download-uk.oracle.com/docs/cd/B14117_01/java.101/b10983/datamap.htm#sthref185
says JPublisher can publish records too.
But when I change the example given at http://download-uk.oracle.com/docs/cd/B14117_01/java.101/b10983/datamap.htm#sthref190 as following:
PACKAGE "COMPANY" AS
type emp_rec is record (empno number, ename varchar2(10));
type emp_list is varray(5) of emp_rec;
type factory is record (
name varchar(10),
emps emp_list
function get_factory(p_name varchar) return factory;
END;
then I see <unknown type or type not found> at sql or java files generated. Any ideas?

Calling a COBOL stored proc from Java Servlet

I am trying to call a COBOL stored proc from a Java Servlet. The stored proc is stored on a DB2 database. I need to send 6 inputs to the COBOL stored proc and the output will be the return code of the stored proc. I'm not sure if I'm going about this the right way. This is how my code looks...
public int callStoredProc(CallableStatement cstmt,
Connection con,
String sYear,
String sReportNbr,
String sSystemCode,
String sUserId,
String sModuleNbr,
String sFormId){
int iParm1 = 0;
try{
Class.forName ("sun.jdbc.odbc.JdbcOdbcDriver");
catch(ClassNotFoundException ex){
System.out.println("Failed to locate database driver: "
+ ex.toString());
return iParm1;
try{
cstmt = con.prepareCall("{? = CALL MKTPZ90C
cstmt.registerOutParameter(1, Types.INTEGER);
cstmt.setString(2, sYear);
cstmt.setString(3, sReportNbr);
cstmt.setString(4, sSystemCode);
cstmt.setString(5, sUserId);
cstmt.setString(6, sModuleNbr);
cstmt.setString(7, sFormId);
cstmt.execute();
iParm1 = cstmt.getInt(1);
CloseSQLStatement(cstmt);
catch(SQLException ex) {
CloseSQLStatement(cstmt);
System.out.println("SQL exception occurred:" +
ex.toString());
return iParm1;
return iParm1;
Could someone tell me if this is the right way to go about doing this?
Thanks!!!!!!

I didn't see the code where you create the database connection (variable "con"). However, the answer to your question "Is this the right way...", for me, is "Anything that works is the right way." So try it. That's a first approximation, but once you have something that works you can start on improving it, if that becomes necessary.

Calling stored procedures in Sybase from java

Hi,
I am using the following stored procedure in Sybase
use xyzdb
go
-- drop procedure if it already exist
if object_id('up_name_select') is not null
begin
drop procedure up_name_select
end
go
create procedure up_name_select

@firstname     char(40),
@lastname     char(40)
as
select zid,
firstname,
lastname
from name
where zid = @zid or
(lastname like @lastname or firstname like @firstname)
go
-- update documentation records in object_docs
delete object_docs
from object_docs
where object_name = "up_name_select"
go
insert into object_docs values("up_name_select","Selects records from the name table based upon the values of the input parameters.")
go
-- update documentation records in column_docs
delete column_docs

begin
print "Procedure up_name_select created."
grant execute on up_name_select to developer_role

This stored procedure selects the values from the table "name" for a given where condition (if I am not wrong).
Can any one give me sample java code to select the records from the table "name" for a given zid.
Thankyou in advance.

Calling a SP or Function from Java receiving a geometry(MDSYS.SDO_GEOMETRY)

Hi there,
What I want to do is: calling a stored procedure OR function from Java with a String-variable as input and receiving a geometry (SDO_GEOMETRY).
I’m facing currently the problem of calling a stored function on oracle 11g from Java using JPA (EclipseLink), Spring 2.5.6 returning an MDSYS.SDO_GEOMETRY object.
I’ve tried to call a stored procedure with MDSYS.SDO_GEOMETRY as an output parameter instead, but with no success.
The function’s signature looks like this:
CREATE or REPLACE
FUNCTION GET_GEO_BRD_FUNCTION(p_geo_brd_id IN VARCHAR2) RETURN MDSYS.SDO_GEOMETRY AS
sdo_geom    MDSYS.SDO_GEOMETRY := null;
BEGIN
/* do some fancy stuff on the database side */
SELECT sp_geom
    INTO sdo_geom
    FROM geo_brd WHERE id = p_geo_brd_id;
RETURN sdo_geom;
END;
The calling code looks like this:
MyClass extends JpaDaoSupport{
   /** logger */
   protected static final ILogger LOG = LogFactory.getLogger(MyClass.class);
    * {@inheritDoc}
    * @see com.example.MyClass#calculateGeometry(java.lang.String)
   @Override
   public JGeometry calculateGeometry(final String id) {
       JGeometry geometry = null;
       final JpaCallback action = new JpaCallback() {
            @Override
            public Object doInJpa(final EntityManager em) throws PersistenceException {
               final Session session = JpaHelper.getEntityManager(em).getActiveSession();
               final StoredFunctionCall functionCall = new StoredFunctionCall();
               functionCall.setProcedureName("GET_GEO_BRD_FUNCTION");
               functionCall.addNamedArgument("p_geo_brd_id");
               functionCall.setResult("sdo_geom", Oracle.sql.STRUCT.class);
               final ValueReadQuery query = new ValueReadQuery();
               query.setCall(functionCall);
               query.addArgument("p_geo_brd_id");
               final ArrayList args = new ArrayList();
               args.add("2e531e62-2105-4522-978a-ab8baf19e273");// hardcoded for test
               final Object result = session.executeQuery(query, args);
               return result;
    final STRUCT result = (STRUCT) this.getJpaTemplate().execute(action);
    try {
       geometry = JGeometry.load(result);
    } catch (final SQLException e) {
       MyClass.LOG.error("Error loading JGeometry from STRUCT.", e);
       return null;
    return geometry;
And when I execute the query I get the following error:
Internal Exception: java.sql.SQLException: ORA-06550: Row 1, Column 13:
PLS-00382: expression is of wrong type
ORA-06550: Row 1, Column 7:
PL/SQL: Statement ignored
Error Code: 6550
Call: BEGIN ? := GET_GEO_BRD_FUNCTION(p_geo_brd_id=>?); END;
     bind => [=> sdo_geom, 2e531e62-2105-4522-978a-ab8baf19e273]
Query: ValueReadQuery()
So I thought may be let's try it with a stored procedure instead...
The procedure looks like this:
CREATE or REPLACE
PROCEDURE GET_GEO_BRD_PROCEDURE(p_geo_brd_id IN VARCHAR2, sdo_geom OUT MDSYS.SDO_GEOMETRY) AS
BEGIN
/* do some fancy stuff on the database side */
SELECT sp_geom
    INTO sdo_geom
    from geo_brd where id = p_geo_brd_id;
END;
The calling Java code in case of the stored procedure looks like this (only the content of the JPACallback has changed):
@Override
public Object doInJpa(final EntityManager em) throws PersistenceException {
    final Session session = JpaHelper.getEntityManager(em).getActiveSession();
    final StoredProcedureCall spCall = new StoredProcedureCall();
    spCall.setProcedureName("GET_GEO_BRD_PROCEDURE");
    spCall.addNamedArgument("p_geo_brd_id", "p_geo_brd_id", String.class);
    spCall.addNamedOutputArgument("sdo_geom", "sdo_geom", OracleTypes.STRUCT);
    final ValueReadQuery query = new ValueReadQuery();
    query.setCall(spCall);
    query.addArgument("p_geo_brd_id"); // input
    final List args = new ArrayList();
    args.add("2e531e62-2105-4522-978a-ab8baf19e273");// hardcoded for test
    final Object result = session.executeQuery(query, args);
    return result;
And when I execute the query I get the following error:
java.sql.SQLException: ORA-06550: Row 1, Column 13:
PLS-00306: wrong number or types of arguments in call to 'GET_GEO_BRD_PROCEDURE'
ORA-06550: Row 1, Column 7:
PL/SQL: Statement ignored
So both exceptions look quite similar.
I guess in both cases the exception description leads to the assumption, that the wrong type for the return value / output parameter is used…
So - how can a receive a MDSYS_SDO_GEOMETRY object from a stored procedure or stored function in Java ?
What is wrong in the Java code?
Thank you in advance for any suggestions!
Yours,
Chris

Thanks, that did the trick! ;-)
Here is now the code for stored procedure and function for anybody else encountering the same troubles... (be aware of the parameter order and/or naming!)
Code for stored functions:
final JpaCallback action = new JpaCallback() {
@Override
public Object doInJpa(final EntityManager em) throws PersistenceException {
     final Session session = JpaHelper.getEntityManager(em).getActiveSession();
       * Using CallableStatement for stored functions
      STRUCT st = null;
      CallableStatement cs = null;
      final DatabaseLogin login = session.getLogin();
      final Connection _conn = (Connection) login.connectToDatasource(session.getDatasourceLogin().buildAccessor(), session);
      try {
         try {
            cs = _conn.prepareCall("{? = call GET_GEO_BRD_FUNCTION(?)}");
            cs.registerOutParameter(1, OracleTypes.STRUCT, "MDSYS.SDO_GEOMETRY");
            cs.setString(2, "2e531e62-2105-4522-978a-ab8baf19e273");//TODO: hardcoded for test
            cs.execute();
         } catch (final SQLException e) {
            MyClass.LOG.error("An exception occured calling the stored procedure", e);
         if (cs != null) {
            //reading geometry from the database
            try {
               st = (STRUCT) cs.getObject(1);
            } catch (final SQLException e) {
               MyClass.LOG.error("An exception occured converting the query result to oracle.sql.STRUCT", e);
      } finally {
         try {
            if (_conn != null && !_conn.isClosed()) {
                _conn.close();
         } catch (final SQLException e) {
            MyClass.LOG.error("An exception occured on closing the database connection.", e);
      return st;
final STRUCT result = (STRUCT) this.getJpaTemplate().execute(action);
The code for stored procedure solution:
final JpaCallback action = new JpaCallback() {
@Override
public Object doInJpa(final EntityManager em) throws PersistenceException {
      final Session session = JpaHelper.getEntityManager(em).getActiveSession();
       * Using CallableStatement for stored procedure
      STRUCT st = null;
      CallableStatement cs = null;
      final DatabaseLogin login = session.getLogin();
      final Connection _conn = (Connection) login.connectToDatasource(session.getDatasourceLogin().buildAccessor(), session);
      try {
         try {
            cs = _conn.prepareCall("{call GET_GEO_BRD_PROCEDURE(?,?)}");
            cs.setString("p_geo_brd_id", "2e531e62-2105-4522-978a-ab8baf19e273");
            cs.registerOutParameter("sdo_geom", OracleTypes.STRUCT, "MDSYS.SDO_GEOMETRY");
            cs.execute();
          } catch (final SQLException e) {
            MyClass.LOG.error("An exception occured calling the stored procedure", e);
          if (cs != null) {
            //reading geometry from the database
            try {
               st = (STRUCT) cs.getObject("sdo_geom");
            } catch (final SQLException e) {
               MyClass.LOG.error("An exception occured converting the query result to oracle.sql.STRUCT", e);
       } finally {
          try {
            if (_conn != null && !_conn.isClosed()) {
               _conn.close();
          } catch (final SQLException e) {
            MyClass.LOG.error("An exception occured on closing the database connection.", e);

JAVA DOA:
new SqlParameter("pColSort", Types.ARRAY, "HTP.STRINGARRAY"),I don't know much (??) java and can't understand your error messages as they are not in english.
But I have a feeling that the error is because either
a) "Types.ARRAY" in Java world probably does not map to an index-by table in oracle or
b) the array must be created as a SQL TYPE and not as a package variable or
c) both of the above
You may want to try following approaches
1) Change the array type declaration to nested table i.e. use "type STRINGARRAY is table of varchar2(256)"
2) If the above does not work, then create a sql type (using CREATE TYPE statement) to create STRINGARRAY as a SQL type of varchar2(256)
Hope this helps.

CALLING a STORED SQL FUNCTION from Java 1.1.8

I am trying to execute a stored function in JAVA 1.1.8, from an Oracle
8i Database. My stored function is simple, it converts an Input Number to an output TIME string. I am unsure how to code the call from Java. Are SQL STORED PROCEDURES treated the same as SQL STORED FUNCTIONS? Do you use the CallableProcdure class or something else?
Thanks for your input.

yep - same way. Except no return value.

Call JavaScript method in FXML from java controller

I have fxml like
   <fx:root type="javafx.scene.Group" xmlns:fx="http://javafx.com/fxml">
    <fx:script>
        function applyState(oldState, newState)
    </fx:script>
    ....and controller to it.
The idea is to move some view logic to fxml file.
So, when I need to change some view state, I want to call applyState from java code.
The question is how to do it.
What I have found:
We can get
fxmlLoader.getNamespace().get("applyState")and receive sun.org.mozilla.javascript.internal.InterpretedFunction.
NetBeans see this class. But while building the project i have an error
error: package sun.org.mozilla.javascript.internal does not exist
But this class really exists in rt.jar in JRE.
After that I have stopped digging into this.
I suspect that using internal API is not a good idea to call this InterpretedFunction.
Can somebody suggest how can I make such an invocation?
Edited by: 940811 on Nov 19, 2012 11:21 PM

Until JavaFX doesn't expose the ScriptEngine instance of FXMLLoader, there's no way to communicate (Java <-> Javascript) with the <fx:script>.
But, if you want to rely on a hack, you can do this:
    private ScriptEngine extractScriptEngine(FXMLLoader loader) {
        try {
            Field fse = loader.getClass().getDeclaredField("scriptEngine");
            fse.setAccessible(true);
            return (ScriptEngine) fse.get(loader);
        } catch (IllegalAccessException | NoSuchFieldException | SecurityException ex) {
            Logger.getLogger(BrowserFXController.class.getName()).log(Level.SEVERE, null, ex);
        return null;
    }

Calling a VB Com component from Java

Hi,
I wish to call some legacy VB 6 COM dlls from some new Java code I am writing. I was looking (just read quickly haven't tried the examples yet) at the ActiveX Bridge documentation and get the impression that it only goes one way -i.e. make Java into an ActiveX Component to be used from VB, whereas I wish to call VB from Java.
Have I missed something or is this not the way to go to get to the legacy code?
The legacy code also has an MIDL file. Ideally, I would love to just be able to access that from Java, but I can't find any (non-Microsoft VJ++ based) tools to help with either converting MIDL to IDL so I can use Sun's idlj.exe or just converting the MIDL to Java.
Any pointers/tips on any of this would be appreciated.
Thanks,

I looked at Jacob, but didn't get far either.
Right now I'm looking at Jawin -
http://jawinproject.sourceforge.net/jawin.html. Not
making a lot of headway yet.
IDL is OMG's IDL (Interface Definition Language) -
http://www.omg.org/gettingstarted/omg_idl.htm.
MIDL is Microsoft's version of IDL for COM - I believe
it uses IDL., but can't seem to find a conversion
tool.
idlj.exe is in the bin directory of whatever JDK you
have loaded. This tool will convert OMG IDL into Java.
Good luck to you.Hi,
I am facing a similar problem. I need to access a vb dll methods. I took and look at jawin and installed it.
I want to invoke a method in the dll from my servlet.
So do I have to create stubs for it. I opened the Type Browser that comes with jawin. It is a GUI through which I am supposed to create stub java files for that dll. But I am getting this error:
[EXCEPTION] InfoPanel.generateInfo() failed to generated info
org.jawin.browser.xsl.TransformationException: TransformationManager.cacheStyles
heet() failed to compile stylesheet from: stylesheets/info/library.xsl - javax.x

Is anyone sucessfully able to generate stub files for the dll in jawin using Type Browser ?
Please let me know

How to call sql procedure with parameter from java

Hello,
i am trying to call one sql procedure with two parameters from java.
the first parameter is In parameter, the second is OUT.
the return value of this java method should be this second parameter value.
the following is my java code:
protected String getNextRunNumber() {
     String runnumber=null;
     String sql = "{call APIX.FNC_SST_EXPORT.GET_NEXT_RUNNUMBER (?,?)}";
CallableStatement state = null;
try{
     Connection con= getDatabaseConnection();
     state = con.prepareCall(sql);
     state.setString(1, m_appKeyExport);
     state.registerOutParameter(2,Types.NUMERIC,0);
     state.execute();
ResultSet resultR = (ResultSet)state.getObject(2);
     while (resultR.next()) {
          runnumber=resultR.getBigDecimal(1).toString();
catch (SQLException e){System.out.println("You can not get the export next run number properly");}
return runnumber;
i got error message like:
java.lang.ClassCastException: java.math.BigDecimal
As far as i knew, if the parameter is number or decimal, we should give also the paramer scale to the method: state.registerOutParameter(), but i still get this error message.
Please help me to solve this problem.
Thanks a lot.

state.execute();
i try to use debug to find the problem, in this line, i saw
OracleCallableStatement(OraclePreparedStatement).execute() line: 642 [local variables unavailable]
is this the problem?

Call an interactive UNIX command from java

Hi,
I want to call a UNIX command from java. When issue the command 'htpasswd -c filename username' on UNIX terminal, it asks for the new password and the then confirmation password again (yeah, unfortunately the htpasswd installed on our system does not allow you proivde the password on the command line. So have to work interactively ). Now, I have written a simple java program RunCommand.java. I am hardcoding the password for the htpasswd command in the file (in the real situation, password will be generated dynamically). I want to issue 'java RunCommand' on the UNIX command line and get back the command prompt without being asked for the password twice. The code is below, but the Outputstream does not work as expected. It always asks for inputs. Any idea? Many thanks.
import java.io.*;
public class RunCommand {
public static void main(String args[]) throws Exception {
String s = null;
try {
String cmd = "htpasswd -c filename username ";
// run a Unix command
Process p = Runtime.getRuntime().exec(cmd);
BufferedReader stdInput = new BufferedReader(new InputStreamReader(p.getInputStream()));
BufferedReader stdError = new BufferedReader(new InputStreamReader(p.getErrorStream()));
OutputStream stdOut = p.getOutputStream();
String pswd = "mypassword";
while ((s = stdInput.readLine()) != null) {
     s = stdInput.readLine();
     stdOut.write(pswd.getBytes());
     stdOut.flush();
System.out.println("Here is the standard error of the command (if any):\n");
while ((s = stdError.readLine()) != null) {
System.out.println(s);
stdOut.close();
stdInput.close();
stdError.close();
System.exit(0);
catch (IOException e) {
System.out.println("exceptions caught: ");
e.printStackTrace();
System.exit(-1);
