How to discover java 1.1.4 incompatible code
Hi all!
I tried to make an applet java 1.1.4 compatible (for M$ VM) but I get a NoSuchMethodError exceptions. I thought that pass -target 1.1 parameter to compiler I solved de problem, but not.
How can I discover the java 1.1.4 code incompatible?
thanks a lot.
Sergio Mart�n
You should file a bug report on this. The original toString() (with no argument has been around since 1.1) but the overloaded method (with a character argument) is available only since 1.4 -- but the -target compiler option should have detected and report the problem (you wouldn't by any chance suppress the warning with a -nowarn compiler option, would you?).

Hello Friends,
I just installed ECC 5.0. Is java webdynpro already installed with ECC 5.0?? If not how to install it?? if yes how to configure it?? And how to run java webdynpro?? help me please
ThanksNo, not required.
You will need to maintain JCo destinations when you deal with your backend R/3 system from WD but as of now you don't need to configure anything.
Just install and start creating your project in WD Java.
Happy Learning

Thanks you very much.It is unclear where you are having a problem. Is your issue at runtime (when the form runs in the browser) or when working in the Builder on the form?
Also be aware that you will need to sign your jar and include some new manifest entries. Refer to the Java 7u51 documentation and blogs that discuss the changes.

How to use java programe in oracle form
Hello Expert,
My Config is : -
Forms [32 Bit] Version 11.1.1.3.0 (Production)
Jdeveloper - 10.1.3
I want to use the java programe in form builder. I create the one java class in Jdeveloper -
package demo;
import java.net.InetAddress;
import java.net.NetworkInterface;
import java.net.SocketException;
import java.net.UnknownHostException;
public class get_info{
public static void main(String[] args){
ch_add();
public static void ch_add()
InetAddress ip;
try {
ip = InetAddress.getLocalHost();
/*System.out.println("Current IP address : " + ip.getHostAddress()); */
NetworkInterface network = NetworkInterface.getByInetAddress(ip);
byte[] mac = network.getHardwareAddress();
/*System.out.print("Current MAC address : "); */
StringBuilder sb = new StringBuilder();
for (int i = 0; i < mac.length; i++)
sb.append(String.format("%02X%s", mac[i], (i < mac.length - 1) ? "-" : ""));
System.out.println(sb.toString());
} catch (UnknownHostException e) {
e.printStackTrace();
} catch (SocketException e){
e.printStackTrace();
and this into Formweb.cfg and default.env and also add into Form_class_path. After that i import this java into forms.

Thanks.This depends on the version of your Netweaver Java AS. If you are running 7.0, you will have to use the Jco framework. The Jco framework is deprecated since 7.1 though. If you want to build a RFC server in 7.1 or higher, it is adviced that you set it up through JRA.

How to access java method in JSP
Hi all,
I need to access java class (abstract portal component) method doContent() in a JSP which is under PORTAL-INF/jsp folder.
I did
<%@ page import = "com.mycompany.Aclass" %>
<%com.mycompany.Aclass a = new com.mycompany.Aclass (); %>
Aclass is coming as autofill/prepopulated with cntrl+space
Till this time, it is working. no errors. But when I do
a.
a. (a dot) no methods are populating (autofill..cntrl+space) or If I forcebly add method a.doContent(req,res)... at runtime its giving error.
It's not only with doContent method... Its with any simple methods in that class or any other class.
(Other than doContent method in the APC java class are prepopulating/autofilling but giving error in runtime)
Can anyone help me... how to access java method in JSP.

You might accomplish your goal using external operating system commands.
1) Define in SM69 an external command, letu2019s say ZJAVA. This command will execute a script on the operating system, letu2019s call it calljava.sh.
2) In script calljava.sh you just call java, passing some parameters. For example, java $1 $2 $3 $4 $5 $6 $7
3) In your ABAP program you call the ZJAVA external command and pass parameters to it. Of course, one of the parameters must be your Java program name.
CALL FUNCTION 'SXPG_COMMAND_EXECUTE'
EXPORTING
commandname = l_command
additional_parameters = l_param
