Java Program Call from PLSQL

First I have created two Java files
FileName1-TestPLSQL.java
package TestJava;
public class TestPLSQL {
* @param args
public static void main(String[] args) {
// TODO Auto-generated method stub
test2.world();
FilaName2-test2.java
package TestJava;
public class test2 {
   public static void world()
    System.out.println("Hello world");
Then i have loaded the class in Oracle using Loadjava-
loadjava -user TEST/TEST -v TestPLSQL.java
loadjava -user TEST/TEST -v test2.java
It successfully loaded without any error.
Then i have created one function-
create or replace
FUNCTION F_JAVA_PGM
/*Specify the return type as per the method in the java class*/
RETURN VARCHAR2
AS
/*Specify the external programs base language*/
LANGUAGE JAVA NAME 'TestJava.TestPLSQL(java.lang.String)
return java.lang.String';
While executing the below query -
SELECT F_JAVA_PGM FROM DUAL;
Its giving error-
ORA-29540: class TestJava does not exist
Can anybody help me on this?

The call specification is incorrect :
You must publish a method, not a class.
None of the methods return a value, why are you creating a function ?
So, in short, for the specific test case you've submitted here, use a procedure that interfaces the TestJava.TestPLSQL.main method with a String array parameter :
create or replace procedure P_JAVA_PGM
AS LANGUAGE JAVA
NAME 'TestJava.TestPLSQL.main(java.lang.String[])';
Tested OK after loading the sources directly via CREATE JAVA SOURCE :
create or replace and compile java source named file2 as
package TestJava;
public class test2 {
   public static void world()
    System.out.println("Hello world");
create or replace and compile java source named file1 as
package TestJava;
public class TestPLSQL {
* @param args
public static void main(String[] args) {
// TODO Auto-generated method stub
test2.world();
create or replace procedure P_JAVA_PGM
AS LANGUAGE JAVA
NAME 'TestJava.TestPLSQL.main(java.lang.String[])';

Perl script calling a java program

Hello,
I have the following perl script that executes a java program called TestSe. It passes its QUERY_STRING to the java program after printing it.
#!/usr/bin/perl
print "Content-type: text/html\n\n";
$in = $ENV{'QUERY_STRING'};
print $in;
exec 'java TestSe '.$in;
This script in placed in a cgi-bin directory on a server.
This script works when i run it manually and hardcode a string value in $in by doing
$in="Acheck";
It prints 'Acheck' on the screen and invokes the java program with Acheck as the parameter.
I tested it by typing
'perl try.cgi' on the shell after logging into the server.
However when I execute this script via. a browser then it does not exec the java program.
The QUERY_STRING is the papameter passed to this script by an html form in a browser that invokes it. The script can print the value of $in in the new browser window that it creates but it is not execing the java program.
Does anyone kow why?
Thanks

Perhaps java isn't in the PATH for the server

How to do "java Program 50 7" when using Eclipse?

If you use the command-line environment to compile and run a java program called Sample.java instead of using Eclipse, you could compile by writing "java Sample 30 5" or replace the 30 and 5 with other numbers (lets suppose the Sample.java needs 2 int inputs). How would you do the equivalent of that when using Eclipse?
Thanks!

In the Run , there is an arguments tab ..

How a java program is executed ?

Hi,
I would like to understand what a java program calls at first. Is it the main() ?
Is it the same as C++ ?
Is it different for an applet?
thanks
djb

For an application, yes, public static void main(String[] args)
(unlike C++ you cannot have main return an int, and it must have a String[] as a parameter)
For an applet it calls public void init(), then usually public void start()

Execing a java program from a perl script

Hello,
I have the following perl script that executes a java program called TestSe. It passes its QUERY_STRING to the java program after printing it.
#!/usr/bin/perl
print "Content-type: text/html\n\n";
$in = $ENV{'QUERY_STRING'};
print $in;
exec 'java TestSe '.$in;
This script in placed in a cgi-bin directory on a server.
This script works when i run it manually and hardcode a string value in $in by doing
$in="Acheck";
It prints 'Acheck' on the screen and invokes the java program with Acheck as the parameter.
I tested it by typing
'perl try.cgi' on the shell after logging into the server.
However when I execute this script via. a browser then it does not exec the java program.
The QUERY_STRING is the papameter passed to this script by an html form in a browser that invokes it. The script can print the value of $in in the new browser window that it creates but it is not execing the java program.
Does anyone kow why?
Thanks

Also if you invoke this as a CGI, the server is going to say it got a 5xx error (server exception). That's because the first output of the perl script is going to be that query string, which isn't a proper HTTP header. The server is expecting the CGI to start out with HTTP headers (such as Content-type, Location, Status) and then a blank line.

Error while running Java program which call a file upload servlet

Hi all,
I have a java program which calls a servlet and sends the file to be uploaded by the servlet. I used Jbuilder to create java program and servlet program. I compiled both the programs and compilation suceeded and my class files are avaialbe in
WEB-INF/classes/content directory. But now I am trying to run the Java program(this contains main method) from the command prompt, which should inturn call my servlet.(I have web.xml file inside WEB-INF dir). But I receive the following error

My dir strcture is as below
TOMCAT_HOME/webapps/content/WEB-INF/classes/content/*.class
I am not able to figure out the error, can anyone throw some light on this issue.

You are trying to invoke the class from the command prompt. My guess is that MultiContentSender contains a package, which means that you'll need to add your WEB-INF\classes directory to the classpath before it will work. Classes stored in this directory are expected to be invoked through tomcat, which builds it's own classpath.

How to call SAP Webservice in standalone java program

Hi,
In our Java application, we want to use the SAP Webservices. I dont know much about authentication mechanism used by SAP. Can any one please help me with any sample code how to Call SAP webservice in Standalone Jave Program. I searched alot on the web regarding this, but helpless. Please help me.
Thanks,
Mohan

Hi Mohan,
You need an account for the ES Workplace. I'm afraid this is not free, e.g. check [SAP NetWeaver, Composition Subscription|https://www.sdn.sap.com/irj/sdn/subscriptions/composition].
But I thought you wanted to play with a WSDL [you already had at hand|Sample code to access BAPI Web services from JAVA required;?

Error while calling java program from ABAP

Hi Experts,
We are trying for RFC inbound scenario.
We followed the below blog
/people/gregor.wolf3/blog/2004/08/26/setup-and-test-sap-java-connector-outbound-connection
We are working with SAP JCO 3.0.2
We are getting the error : 'STFC_CONNECTION' could not be found in the server repository.
After I run the Java server program if I execute the RFC destination directly from SM 59 it is showing successful messages.
If I stop the java program then this RFC is failing. Based on this we concluded that RFC to Java connection is working fine.
But as mentioned in blog if we call the RFC Destination from ABAP program it is giving the below error,
'STFC_CONNECTION' could not be found in the server repository.
If we test the RFC destination using RFC_TRUSTED_CHECK standard FM we are getting the below error.
'RFCPING' could not be found in the server repository.
We create the RFC destination of Type : TCP/IP as exactly mention in the blog.
Please help us in resolving this issue.
Thanks
Prince

Pabi,
Using the RFC connection,we can establish a link between Java and SAP.
Afterwards,hope we can call Java program from ABAP.
Below is the sample piece of code to establish RFC connection(link) between Java and SAP.
DATA: REQUTEXT LIKE SY-LISEL,
      RESPTEXT LIKE SY-LISEL,
      ECHOTEXT LIKE SY-LISEL.
DATA: RFCDEST like rfcdes-rfcdest VALUE 'NONE'.
DATA: RFC_MESS(128).
REQUTEXT = 'HELLO WORLD'.
RFCDEST = 'JCOSERVER01'. "corresponds to the destination name defined in the SM59
CALL FUNCTION 'STFC_CONNECTION'
   DESTINATION RFCDEST
   EXPORTING
     REQUTEXT = REQUTEXT
   IMPORTING
     RESPTEXT = RESPTEXT
     ECHOTEXT = ECHOTEXT
   EXCEPTIONS
     SYSTEM_FAILURE        = 1 MESSAGE RFC_MESS
     COMMUNICATION_FAILURE = 2 MESSAGE RFC_MESS.
IF SY-SUBRC NE 0.
    WRITE: / 'Call STFC_CONNECTION         SY-SUBRC = ', SY-SUBRC.
    WRITE: / RFC_MESS.

Problem while calling a Webservice from a Stand alone java program

Hello Everyone,
I am using a java program to call a webservice as follows. For this I have generated the client proxy definition for Stand alone proxy using NWDS.
Now when I call the method of the webservice I am getting the correct result but along with the result I am getting one error and one warning message in the output.
The java code to call the webservice is as follows.
public class ZMATRDESCProxyClient {
     public static void main(String[] args) throws Exception {
          Z_MATRDESC_WSDService ws = new Z_MATRDESC_WSDServiceImpl();
          Z_MATRDESC_WSD port = (Z_MATRDESC_WSD)ws.getLogicalPort("Z_MATRDESC_WSDSoapBinding",Z_MATRDESC_WSD.class);
          String res = port.zXiTestGetMatrDesc("ABCD134");
          System.out.print(res);
The result I am getting is :
Warning ! Protocol Implementation [com.sap.engine.services.webservices.jaxrpc.wsdl2java.features.builtin.MessageIdProtocol] could not be loaded (NoClassDefFoundError) !
Error Message is :com/sap/guid/GUIDGeneratorFactory
<b>Material Not Found</b> -
> This is the output of webservice method and it is right.
Can any one please let me know why I am getting the warning and error message and how can I fix this.
Thanks
Abinash

Hi Abinash,
I have the same problem. Have you solve that problem?
I am using a java program to call a webservice too. And I have generated the client proxy definition for Stand alone proxy using NWDS. When I call the method of the webservice I am getting the correct result but along with the result I am getting one error and one warning message in the output.
The java code to call the webservice is as follows.
MIDadosPessoaisSyncService service = new MIDadosPessoaisSyncServiceImpl();
MIDadosPessoaisSync port = service.getLogicalPort("MIDadosPessoaisSyncPort");
port._setProperty("javax.xml.rpc.security.auth.username","xpto");
port._setProperty("javax.xml.rpc.security.auth.password","xpto");
String out = port.MIDadosPessoaisSync("xpto", "xpto");
System.out.println(out);
The result I am getting is :
Warning ! Protocol Implementation [com.sap.engine.services.webservices.jaxrpc.wsdl2java.features.builtin.MessageIdProtocol] could not be loaded (NoClassDefFoundError) !
Error Message is :com/sap/guid/GUIDGeneratorFactory
<b>The result of the WS is correct!!!</b>
The Java project does not have any warning. But the stand alone proxy project has following warnings associated with it.
This method has a constructor name     MIDadosPessoaisSync.java
The import javax.xml.rpc.holders is never used     MIDadosPessoaisSyncBindingStub.java
The import javax.xml.rpc.encoding is never used     MIDadosPessoaisSyncBindingStub.java
The constructor BaseRuntimeException(ResourceAccessor, String, Throwable) is deprecated     MIDadosPessoaisSyncBindingStub.java
It is very similar with your problem, could you help me?
Thanks

To run a java program via a batch file,when called from a web server

REM This batch file runs the Spider with the [-v] option.
REM Lines 51 through 54 are simple DOS commands..they call the Spider
REM The location of the Spider package is the important piece of information here...
REM a batch file has access to the whole computer where the server resides.
setlocal
set JDK=C:\j2sdk1.4.1_01
set PATH=%JDK%\bin;.;%PATH%
CLASSPATH=%JDK%\jre\lib\*.jar;.;%JDK%\jre\lib\ext\*.jar;.;%CLASSPATH%
java spiderpackage.EntryPoint -v
endlocal
I am trying to run this batch file from my web server.I can see nothing on my browser.I can run the same program from my machine but unable to run from web server.what should I do?

I am making my question more clear...
I have a Windows batch (*.bat) file that echoes some html, then calls a java program the output of which is html as well, then echoes the final html.
To make sure that the java program gets properly executed, I set the necessary environment variables (e.g., JDK, PATH, CLASSPATH, etc.). The script looks something like this:
setlocal
set JDK=path_to_JDK
set PATH=path_to_java
set CLASSPATH=path_to_java_classes
echo ^<html^>^<body^>
call java foo
echo ^</body^>^</html^>
endlocal
The idea, of course, is to call this script through a browser, on a web server.
Curiously, both echo lines return to the browser just fine, but any output from
the java program (which just writes html to STDOUT) does not make it back.
Can someone explain to me why this is happening? How do I set things up so that the output (STDOUT and STDERROR) from the java program make it back to the browser?

Hi Priyanth,
I am not sure but check this out
If you are using any commands , check if that command is configured in SM69

I am trying to call this batch file from my web server but I am unable to capture the result.I tried to append the result to a file but It writes nothing to it.What should I do to proceed?

I am not entirely sure if this is analogous, but I once wrote a PHP script uner Linux that invokes java and returning the output. I found that it was necessary to pipe the output of the Java program from stderr to stdout in order to properly receive it in PHP. The command would be as follows:
java spiderpackage.EntryPoint -v 2>&1
The pipe syntax (2>&1) should be exactly the same under MSDOS. So add that, and then continue as normal (appending it to a file or whatever else you want to do). Hope that helps
