How to test Java Proxy Classes in Portal

I have created a Java Project in NWDS and have added Java Proxy classes for BAPI_EMPLOYEE_GETDADA. I have created a main class to call the Java Proxy Classes.
I have noticed that I can not export it as .PAR file so I exported it as .JAR file. Now I logged into my Portal Server to test this new Java Proxy class but I do not see the .JAR file that I had created. Do I need to explicitly import it into Portal Server (I was thinking that similar to .PAR files, .JAR file will get transferred to the portal server automatically upon chosing Export from NWDS)
I am also not sure if I can create JAVA iView based on the .JAR file.
Please advise me on how can I test my Java Proxy Class.
Thanks a lot in advance.

Sanjay Gera

Hi,
You can try with HTTP as sender. Send a HTTP request using HTTP Client code and check out the response.
For HTTP, sender communication channel is not required. All other steps in Configuration will be similar to any simple scenario.

RFC lookup with java proxy class, how do I use "fromXml()"?

Hi,
I'm trying to do an RFC lookup in XI using java proxy classes (SAP Enterprise Connector).
The XMLPayload comes from a java proxy class which has been converted to xml using a method called
.fromXml() for this. I just don't know how to use and I can't find any documentation for it.
Would very much appreciate if someone could provide me with an example of how to use this class
Best Regards

Help - how to create java proxy (sender) in NWDS 7.1

Hi,
I am trying to develop a java proxy as sender to send message from WAS to PI.
I am using NWDS 7.1. Let me explain what I have done so far,
1. Received proxy classes from PI
2. Created a EJB Project, imported the proxy classes into EJB project
3. created a EJB bean, local interface in the EJB project and exposed as webservice
4. added the ejb to an ear
5. added reference to the following jar files (external library)
tcaiiproxy_rt_api.jar
com.sap.aii.af.sdk.jar
com.sap.aii.utilxi.server.jar
com.sap.aii.utilxi.core.jar
com.sap.aii.proxy.svc_api.jar
6. able to build and deploy the application
7. able to open the webservice in wsnavigator
Error encountered:
"Server Exception: javax.ejb.EJBException: nested exception is: java.lang.RuntimeException: java.lang.NoClassDefFoundError: com/sap/aii/proxy/xiruntime/core/AbstractType "
Questions:
1. Which method I should execute / call among all the proxy classes from local bean class to send message to PI?
2. Is it mandatory to add refernces to the application.xml, ejb-jar.xml and other xmls ?
3. How can I test / monitor the message being sent to PI interface?
Thanks and best regards,
Arun prabhu S

How to generate java proxy in PI 7.1

Hi All,
How do I generate java proxy in PI 7.1
I am unable to see the "Generate Java Proxy" in the Tools menu in the Integration Builder

hi ,
As mentioned in the Question, I am unable to find the "Java Proxy Generattion" link in the Int builder.
Also the help doc says:
Java proxy generation is no longer supported in subsequent releases. For new developments or when making significant changes to a service interface, use Java proxy generation in SAP NetWeaver Studio instead. More information: Creating Outside-In Web Services, SAP NetWeaver Developer Studio.
Does that mean that I can no longer generate java proxy from Int builder?

How to call Java API classes from Javafx Main.fx?

Hi
Can anybody let me know how to include java.util.StringTokenizer in Main.fx file of Javafx?
I need to split a concatenated String in Javafx. Is there any example available with anybody on this?
When I use the split() of Javafx, I get error while assigning the value returned by split() to both String and String[] variables:
1. var name = "test|string";
2. var names: String[];
3. var splitName: String = "";
4. names[0] = name.split("|");
5. splitName = names.split("|");
6. var storeName: String[];
Later I need to put the splitName into another String array to have a collection of all the concatenated string in one array.
insert splitName into storeName;
But I get error in line 4 and 5. The split() in javafx returns a String []. Is there anything that I missing here.
Any reply to this post will be highly appreciated. I need this quite urgently.
Thanks & Regards

How to test java printing program without wasting paper?

Hi,
I had written a java program that prints my document. I want to know how people test their printing document generatation program?
Because I think people don;t wastes papers..
So can anyone tell me to test these programs efficiently and preciesly what are the best testing tools available ?
Thank you.

1) find a program that prints to pdf, or some other file
2) print to pdf or some other file instead of printing to a printer.
3) To test it perfectly you will eventually have to waste some paper.

Calling a WSSE Enabled Web Service Through a Java Proxy Class

I am trying to create a client that can access a WSSE enabled web service through
the generated java proxy. For now all I am asking for in the .wsse file is the
username and password with the line <token tokenType="username"/>. In the client
I am setting the username and password token exactly as the BEA documentation
describes:
UserInfo ui = new UserInfo("myuser", "mypassword");
session.setAttribute(WSSEClientHandler.REQUEST_USERINFO, ui);
Yet I am getting the following error message when I try to run the client:
java.rmi.RemoteException: SOAP Fault:javax.xml.rpc.soap.SOAPFaultException:
EJB Exception: ; nested exception is:
com.bea.wlw.runtime.jws.wssecurity.exception.WLWWSSEException: Policy
requires Message to contain UsernameToken, UsernameToken not found in the Message.
Can anyone tell me what I am missing?
Thanks,
John

Hi John,
In your standalone client, use the following two properties to send a
user name and password to the service so that the client can
authenticate itself: javax.xml.rpc.security.auth.username
javax.xml.rpc.security.auth.password
See the docs [1]
Hope this helps,
Bruce

How to use java.lang.Class.getMethod() and java.lang.reflect.Method.invoke(

I want to call a specified method of one class dynamically. I use the method
"getMethod()" in package "java.lang.Class" to get method and "invoke()" in
" java.lang.reflect.Method " to invoke method.
The problem is as following :
1. There are two argument in this method "getMethod(String MethodName , Class[] paremterTypes)" in package "Class". I have no idea about the second parameter " Class[] parameterTypes ".what does the argument exactly mean ?
2. There are two argument in the method "invoke(object obj, object[] obj)" in package "Method".
I have no idea about the second parameter "object[] obj ".what is mean ?
I pass " null " value to it and it works.But i pass anothers ,jvm will throw exception.

I have a generic Method Executer that has a method like
public Object execute(String className, String methodName, Object args)
    String fullClassName = packageName + className ;
    Class delegateClass = Class.forName(fullClassName);
    BaseDelegate delegate = (BaseDelegate)delegateClass.newInstance();
    Method method = null;
    if (args == null)
        method = delegateClass.getMethod(methodName, new Class[] {});
        obj = method.invoke(delegate,new Object[] {});
    else
        method = delegateClass.getMethod(methodName, new Class[] {args.getClass()});
        obj = method.invoke(delegate, new Object[]{args});
   }This seems to have problems when I call the method from a class like:
execute("CategoryDelegate", "getCategoryById", new Integer(4144));(I get a NoSuchMethodException)
The method I am trying to execute in CategoryDelegate looks like:
public Category getCategoryById(int categoryId) throws DelegateExceptionI think it has to deal with the difference in the way we handle Primitive Wrappers and Objects. Wrapper we have to use Interger.TYPE and with the rest of the Objects we have to use obj.class.
Am I doing something wrong here? Any suggestions to make it work for primitive wrappers as well as Objects?

How to bundle java help class into jar file ?

Hi, all,
I have some package in my project, with which I have a java help jar file as classpath, when I run my project, I need the jh.jar file in directory /jar/jh.jar.
Now, I bundled all my class packages into a jar file, my.jar, together with the /jar directory. When i run my jar file with command:
java -jar my.jar
It tells me couldn't find javahelp class.
What shall I do? How can I create my jar file with the jh.jar?
Thanks in advance.

I think you'd be better off just adding the jh.jar as
a classpath argument and running it like that:
java -classpath /myjavalibdir/jh.jar -jar myjar.jar
...otherwise you're stepping into redistribution of
binary issues licensing-wise. That won't work either; when you run java with the -jar option, it ignores both the -classpath option and the CLASSPATH environment variable. However, it will see jh.jar automatically if you put it in the <path-to-java>/jre/lib/ext directory. But for distribution purposes, it might be simpler just to combime the contents of jh.jar into myjar.jar (if you use Ant, its <jar> task makes that very easy). Or, you can just run it this way:java -classpath myjar.jar;jar/jh.jar MyMainClassBTW, I don't think redistribution is a problem; otherwise how anyone even use JavaHelp?

How to compile .java to .class in .jar file

Hey. I have code to make a .jar file, read .java files, and save them as .class files in the .jar file. When I open the .jar file, it says that the magic numbers on the classes are wrong. So I figured that Java must compile the .java files to .class files in bytecode.
Question: What's the code to compile a string from a .java file to a .class file?
Here's my code:
try {
            // Name of jar file to write
            String archiveFile = Name + ".jar";
            Manifest jman = new Manifest();
            try {
                // Create a manifest from a file
                //InputStream fis = new FileInputStream("manifestfile");
                //Manifest manifest = new Manifest(fis);
                // Construct a string version of a manifest
                StringBuffer sbuf = new StringBuffer();
                sbuf.append("Manifest-Version: 1.0\n");
                sbuf.append("Ant-Version: Apache Ant 1.7.1\n");
                sbuf.append("Created-By: 1.5.0_19-137 (Apple Inc.)\n");
                sbuf.append("Main-Class: Main\n");
                sbuf.append("Class-Path: lib/swing-layout-1.0.3.jar\n");
                sbuf.append("X-COMMENT: Main-Class will be added automatically by build\n");
                // Convert the string to a input stream
                InputStream is = new ByteArrayInputStream(sbuf.toString().getBytes("UTF-8"));
                // Create the manifest
                jman = new Manifest(is);
            } catch (IOException e) {
            FileOutputStream stream = new FileOutputStream(archiveFile, true);// archive file is jar file name
            JarOutputStream out = new JarOutputStream(stream, jman);
            out.putNextEntry(new JarEntry("Main.class"));
            StringBuffer sbuf = new StringBuffer();
            sbuf.append(readTextFromJar("Main.txt")));
            out.write(sbuf.toString().getBytes("UTF-8"));
            out.closeEntry();
            out.putNextEntry(new JarEntry("MainScreen.class"));
            sbuf = new StringBuffer();
            sbuf.append(readTextFromJar("MainScreen.txt"));
            out.write(sbuf.toString().getBytes("UTF-8"));
            out.closeEntry();
            out.putNextEntry(new JarEntry("GCanvas.class"));
            sbuf = new StringBuffer();
            sbuf.append(readTextFromJar("GCanvas.txt"));
            out.write(sbuf.toString().getBytes("UTF-8"));
            out.closeEntry();
            out.close();
        } catch (Exception ex) {
            JOptionPane.showMessageDialog(this, ex.toString(), "BUG!", JOptionPane.INFORMATION_MESSAGE);
            ex.printStackTrace();

So I'm guessing that none of you guys have the knowledge on how to compile a java application within a java application. I was thinking that it had something to do with javac... but I'm unsure.
If no one can answer the question, could someone point me to an expert who would know?

XI: How To Use JAVA generic Class to perform SAP data Lookup........

Hello All,
I want to create a generic class which is used to perorm SAP data lookup.
I don't want to use Jco or RFC channel..
Is there any other way to do this?
waiting for Reply
thank in advance.

Hi,
use RFC channel
you can wrap it up like this:

How to call Java WebDynpro iViews from Portal (Portal Content Directory)

Hello everybody,
I am trying to call a Java WebDynpro iView, which was created within the Enterprise Portal and is stored in the portal content directory (pcd).
I have created an HTML-iView in VC, where I have put in the pcd-link into the default-url field (pcd:portal_content/com.sap.pct/every_user/com.sap.pct.cprxrpm.ppmdc/com.sap.pct.cprxrpm.iviews/com.sap.pct.cprxrpm.iviews_cprojects/com.sap.pct.cprxrpm.cpr_projects). This iView is calling the cProjects WebDynpro Application. But after I run my model, the portal page is running and running, but nothing happens.
I did the same with transactional iView, which was also created in the Portal before. I have also created an HTML-iView in VC, where I have put in the pcd-link into the default-url field (pcd:portal_content/IBU_content/SAP_for_Service_Provider/com.sap.pct.issp.ps.professional_services/com.sap.pct.issp.prs.iviews/com.sap.pct.issp.prs.display_sd). This is working fine!
What I also tried is to call another VC-Model with an HTML-iView. Here I have put-in into the default-url field the pcd-location of my VC-model (pcd:portal_content/IBU_content/SAP_for_Service_Provider/com.sap.pct.issp.vcmodels/com.myComp.myProduct.1DM9.CreateEngagement/com.myComp.myProduct.iviews/com.myComp.myProduct.1G62.Cprojects_neu). This is also running fine!
Now I do not understand the difference between this three objects. There are all iViews within the portal but the WebDynpro iView is not callable through a HTML-iView in VC.
Could you help me in this case? Your help is very appreciated!
Thank you in advance.
Best regards,
Aylin.

Hi Marcel,
when you mean the preview within the portal, yes, it is working fine.
URL is not the way to solve my problem. I am working with IDES-Systems. This is our Demo System within SAP. I have to build my VC-Model in a Master IDES-System which will be transported than into the other IDES-Systems. The URL of the WD is not the same in the other systems. It is changing depending on the several Sysems. But the pcd-location is in all systems the same. Therefore I have to specify the pcd-location of the application.
Is there a restriction with WD within VC?
If we can do some kind of a netmeeting, I can show you my problem exactly.
Thank you.
Regards,
Aylin.

Forums - How to use java.lang.Class.getMethod() and java.lang.reflect.Metho

Method method = objRef.class.getMethod("setMethod", new Class[]{String.class});
Object objReturn = method.invoke(sqlWhere, new Object[] {"any String"});
I can invoke setMethod but I don't know how to invoke getMethod().

How to create Java extension classes in NWDI

Hi !
After having read the thread - Build Error - I've added the crm/home/shr/ext (assembly) under Used DC . But now I am getting the following error - ERROR: crm/home/shr/ext: Build failed for sap.com/crm/home/shr/ext(sap.com_SAP-SHRWEB_1) in variant "default": Illegal component usage: compartment "sap.com_SAP-SHRWEB_1" does not use compartment "sap.com_SAP-JEE_1" of used DC "sap.com/com.sap.tc.Logging"
Can anyone help ?
Best regards,

Hi Sathish,
Thanks for your reply. On detailed analyses, we found that some objects were incorrect in the SLD. They have since been corrected and the DC synced again.
To analyse everything, we have decided to take small steps rather than large leaps. We have now added some small bit of Java code but the build is erroring due to not being able to find com.sap.isa.backend.r3.* jar file. Where can I find this .jar file ? We are using ERP E-Commerce.
Best regards,
Ashok.
Edited by: Ashok on Oct 28, 2009 5:53 PM
Hi !
I found the _com.sap.isa.backend.r3.* file in sap.comcrmisaisacorer3assembly. However, even after adding that jar file onto the Java buildpath of 'crmhomeshrextsap.com', build is failing complaining about the same .jar file. The .jar file doesn't see to be added onto the buildpath during the actual build. Am I missing anything ?

Ashok.
