R/3 connection from servlet page

Helllo,
I have implemented a servlet page from SAP NetWever Developer Studio:
1 - J2EE -> Web Module Project for the development
2 - J2EE -> Enterprise Application Project (EAR) for the deploy
Now I need to access to the R/3 system. It is possible connect to R/3 system from a servlet page? In the portal already exists a system connection created under the section "Syatem Administration -> System Configuration" but I'm trying to implement the connection unsuccessfully (following the Java code used into the servlet):
String sapSystem = "MNT";
IUserAccount uacc = UMFactory.getUserAccountFactory().getUserAccountByLogonId("Administrator");
IUserAccount iuacc = UMFactory.getUserAccountFactory().getMutableUserAccount(uacc.getUniqueID());
IUser user = iuacc.getAssignedUser();
IConnection connection = null;
// get the Connector Gateway Service
IPortalComponentRequest req = (IPortalComponentRequest) request; => HERE Casting error
Object connectorservice = PortalRuntime.getRuntimeResources().getService(IConnectorService.KEY);
IConnectorGatewayService cgService = (IConnectorGatewayService) connectorservice;
ConnectionProperties cp = new ConnectionProperties(user.getLocale(), user);
connection = cgService.getConnection(sapSystem, req);
String res = "", name = "", path = "";
// Get the Interaction interface for executing the command
IInteraction ix = connection.createInteractionEx();
// Get interaction spec and set the name of the command to run
IInteractionSpec ixspec = ix.getInteractionSpec();
String functionName = "Z_R3_FUNCTION";
// Put Function Name into interaction Properties.
ixspec.setPropertyValue("Name", functionName);
// return structure - parametro di export della funzione
String function_out = "P_PAR";
String function_in_value = "VALUE";
RecordFactory rf = ix.getRecordFactory();
MappedRecord input = rf.createMappedRecord("input");
// put function input parameters
input.put("P_KUNNR", function_in_value);
MappedRecord output = (MappedRecord) ix.execute(ixspec, input);
connection.close();
Object result = output.get(function_out);
Anybody knows how implement it?
Thanks and best regards,
Matteo.

Hello Marcos,
I have followed the example shown in your link, I have found all JAR file, the Java code has not error, I hace deployed my project, but the server returns the error:
java.lang.ExceptionInInitializerError: JCO.classInitialize(): Could not load middleware layer 'com.sap.mw.jco.rfc.MiddlewareRFC'
JCO.nativeInit(): Could not initialize dynamic link library sapjcorfc [no sapjcorfc in java.library.path]. java.library.path [/opt/java1.4/jre/lib/IA64W:/opt/java1.4/jre/lib/IA64W/server:/opt/java1.4/jre/../lib/IA64W:/usr/sap/PCT/JC00/j2ee/os_libs::/usr/sap/PCT/JC00/j2ee/os_libs:/usr/sap/PCT/SYS/exe/run:/usr/sap/PCT/SYS/exe/run:/usr/sap/PCT/SYS/exe/run:/oracle/PCT/sapdata4/SP24/LOGS/J2EE/sapinst_exe.252.1243940833:/usr/lib:/usr/sap/PCT/JC00/j2ee/os_libs:/usr/sap/PCT/JC00/j2ee/os_libs:]
I have notice that into the folder "C:\Program Files\SAP\JDT\eclipse\plugins\com.sap.mw.jco\lib" there is the file sapjcorfc.dll
Do you know if I have to put JAR into a particular folder into my project, or I have to do some configuration on the server?
Thanks and best regards,

How to use Oracle Procedures with Servlet page

Hi all
I'm working on Servlet pages and I need to insert and select some records from Oracle database but it has to be done by calling some already written Procedures. I've never really used them before so I'm little lost. I know where the queries are used it'll be Procedures but what is the syntax for it.Can anyone put me in right direction please.
Thanks

Just google it. You will find lots of examples. Here are some :
[http://java.sun.com/docs/books/tutorial/jdbc/basics/sql.html|http://java.sun.com/docs/books/tutorial/jdbc/basics/sql.html]

Oracle XSQL Servlet Page Processor 0.9.9.1 (Technology Preview)

I trying XSQL Servlet in oracle8.1.6,Java Web Server.
When I access http://localhost:8080/xsql/index.html
I am getting this error.
"Oracle XSQL Servlet Page Processor 0.9.9.1 (Technology Preview)
XSQL-013: XSQL Page URI is null or has an invalid format."
Any suggestion....
null

JWS is not one of the supported Servlet Engines in 1.0.0.0 please see the release notes for supported engines (there are lots of them).
The XSQL 1.0.1.0 release will support and
additional set of engines that cause XSQL-013 errors becuase the return null for
the Servlet API call:
req.getRealPath(req.getServletPath());

Java Servlet page not opening error 404

Hi!
I am working with servlets. I compiled the java file and the class file is been moved to
c:\javawebserver2.0\servlets, and the html files moved to public_html. Html files r opening
the classpath is mapped to jsdk.jar i.e

Built-in samples r working without any problem
when i try to run the servlet
Page Not Found error 404 occuring
Please do the favour for me
thanks

404 Not Found means you didn't deploy the app properly.
I think deploying an app like this is a terrible idea. If you have more than one app deployed on a production web server/servlet engine, you wouldn't want to put them all in the same place. "public_html" and the generic "servlets" directory shouldn't be used as dumping grounds for all your apps.
Learn how to deploy using a WAR file. It'll keep all your apps separate and their constitutive parts together.
Why Java Web Server? I don't think anyone uses it seriously anymore. Tomcat is the reference implementation of the servlet/JSP specs. I'd download that and use it instead of JWS. JMO, of course.

Verification Of SQL destils on a servlet page

Hi,
I am just wondering if anyone can help me with my litle problem, I need to read avalue from a database and display it on the servlet page, but the name has to be verified, something like:
SELECT acbalance FROM actable WHERE acname = user
I am wondering if I could read thevariable "user" from the session and verify it that way?
If so, how do I do this?
Or does anyone else have a better idea how I can do this?
Any help greatly appreciated,
Aidan.

More simply you can use a PreparedStatement: SELECT acbalance FROM actable WHERE acname = ?... then, at each call, just use pstatement.setString(1, user)

Restoring of HREF on same servlet page

hi,
i have a servlet page that generating number of hyperlink in form of menu. on clicking any HREF control goes to other page.
till now everything is fine, but i want to display most recent used top 10 HREF on servlet page without affecting the functionality.
Pls help me.

How about counting the clicks in static variables?
Let's assume this:
interface HrfClicks{
       public static int HRF1_CLICKED = 0;
       public static int HRF2_CLICKED = 0;
public class TestServlet extends HttpServlet {
         public void doGet(HttpServletRequest request, HttpServletResponse){
                    HrfClicks.HRF1_CLICKED++;
                   //display the top ten links....etc.
}Is that what you want?
regards....

XSQL Servlet Page Processor 0.9.8.6 won't run

Hi...
I just upgraded the Servlet and keep getting
XSQL-003: Failed to find 'XSQLConnections.xml' file in server CLASSPATH.
XSQL-004: Could not acquire a database connection named: demo
XSQL-007: Cannot acquire a database connection to process page.
The classpaths are all setup correctly and the previous version worked fine. The
setup xml file (XMLConfig.xml) is in the classpath.
From what i can see, XSQLConnections.xml is
not even included in the distribution so i don't understand why i get this error.
I am using Apache + Jrun 2.3.3
thanks for any help
null

That error message is outdated and should read:
Cannot find XSQLConfig.xml in your server-side classpath. The error is definitely that it's not finding XSQLConfig.xml on your classpath. The likely cause is that you did not add the directory:
./xsql/lib
to your CLASSPATH in the JRun Servlet Engine Java environment.

/servlet/page error in portal3p

Experts,
I had upgraded my Portal to 3.0.9 and i am unable to launch the Portal. My diag.cmd says all are fine. The jserv is also fine because my ip/servlet/IsItWorking is working fine. But one thing i notice is I am able to lauch the DAD config portal (i.e) ip/pls/admin_/ page but this does not ask for a login as it is supposed to do in the latest version. Any body has any idea how to solve this?
Thanks in advance,
Ranga

Struts/servlet page flow problem due to j2ee security

Whe I type url such as http://localhost:7777/myapp/action.do, I want to see the execution result page from this action. However the result page will always be index.jsp because j2ee security which I have a loginaction.do and its result page is index.jsp. How can I have overcome this problem.
Thanks,

To give more details about the problem I have, user likes to put a URL in the browser, then press enter. User likes to see the running results. However, user is not able to see the results because j2ee security requires user log in. After sucessful login, user is going to see the index page. My question is how user be able to view his result page after login.
cheers.

Compiling my first servlet page

Hi,
Im not able to compile my servlet.The servlet code is in desktop\java.The servlet.jar is in c:\program files \ apache tomcat 4.0\common\lib
when i give this command
javac HelloServlet.java -classpath " c:\--------" it is not working.I dont know whether this is correct.Please help me out.

Adding the servlet.jar to tomcat won't make the java compiler know where it is unless the code is called from an application in the web container.
use javac -cp "filename"
Otherwise I'd suggest you'd get an IDE to which you add the jar and then compile using the IDE.
Don't waste your time with javac!

Servlet page can't run

Hello buddies,
I am very new with servlet. I encountered some problems during browsing my frist servlet for my personal testing.
I am using Apache Tomcat/4.1.29 as webserver. So I configured as followed inside web.xml which is under Web-INF folder. What happened was just after updating xml file, my applicaiton is failed to start.
Can anybody help me.... please.
The configuration I made inside web.xml is as followed.
<web-app>
<servlet-mapping url-pattern='/hello'
servlet-name='hello-world'/>
<servlet servlet-name='hello-world'
servlet-class='test.HelloWorld'>
<init-param greeting='Hello, World'/>
</web-app>
Yr reviewing & help is very much appreciated.
Thanks so much!

The web.xml snippet you've shown is quite wrong. This is how it should be:
<web-app>
    <servlet>
        <servlet-name>MyServletName</servlet-name>
        <servlet-class>my.package.MyServletClass</servlet-class>
        <init-param>
            <param-name>myParamName</param-name>
            <param-value>myParamValue</param-value>
        </init-param>
    </servlet>
    <servlet-mapping>
        <servlet-name>MyServletName</servlet-name>
        <url-pattern>/hello</url-pattern>
    </servlet-mapping>
</web-app>You can then access this servlet as http://servername/webAppName/hello
Where did you get that web.xml structure anyway? You should probably steer clear of that source.
Also, 4.1 is quite an old version. There have been many changes in Tomcat as well as the Servlet and JSP specs. I'd suggest you upgrade.
P.S. The next time you post, please use code tags. Above the text area while posting/ editing, you'll see a button labelled 'code'. Use that.

Reports Servlet - Page not found

Hi,
We have problems with OracleAS Reports Services. We have installed oracle applicaction server 10g and we create a standalone report server, but when we issue
http://<server>:7778/reports/rwservlet
we get "Page not found" error. We looked at the error.log in Apache/logs directory and it gives:
File does not exist: /app/oracle/product/Reports/Apache/Apache/htdocs/reports/rwservlet
What is the issue? I checked the repserver.conf file, opmn.xml, tnsnames.ora, rwservlet.properties.
Help please. Thanks in advance...

Hello,
In order to "forward" the request to the OC4J OC4J_BI_Forms , some settings are required :
Could you check that mod_oc4j.conf in included in httpd.conf ?
In $ORACLE_HOME/Apache/Apache/conf/httpd.conf
# Include the mod_oc4j configuration file
include "d:\oracle\unified\Apache\Apache\conf\mod_oc4j.conf"
Then, check that there is an Oc4jMount directive for reports :
In $ORACLE_HOME/Apache/Apache/conf/mod_oc4j.conf
Oc4jMount /reports OC4J_BI_Forms
Oc4jMount /reports/* OC4J_BI_Forms
