Trace a java class

Hello!
How can I trace a java class (Logging) which has been created
and located inside src/packages/....
You can see these folders inside Web Dynpro Explorer
after "Dictionaries" node.

Trace java class execution

hi all,
I had a terrible experience recently. There was a Java class which creates some reports and uses some libraries also. This program was developed very primitively and exceptions not handled properly. Last time I observed that program is running and but no output and but no error prompted. (because exception was catched but not handled no even a system out).
So I would like to know any method or technique to trace the situation of class execution and find what operations are blocked

IndiikaYou could use AspectJ to add logging, but a simple thread dump can give you information on blocked threads.

Is that Jasper Exception telling us where the problem is in the jsp, though?
If it is, then "rs" is null in the call rs.next()...which means conn.executeQuery() is returning null. Which means that whatever class conn is (news.conn?) has a problem maybe?That's possible. Though, it may just be the case that the 'conn' object itself is null! That line is the first place where it's being used and there are no checks that I can see...we'll have to wait for the OP to investigate and reply I guess.That's what I originally thought, then I noticed it was saying line 47, which is the rs.next() line. Assuming Jasper is correct in its choice of line, then it's the rs that's null. Which means the conn is doing strange things.
Edit: Now that I think about it, going by the previous thread the OP posted, I'm wondering whether news.conn class is their attempt to move the JDBC stuff out of the JSP page, and it's grabbing the "real" connection (java.sql.Connection) and getting the result set and returning it...or getting something wrong and returning null.

How to use java classes of DC1 in DC2

When I was trying to use a java-class from another DC, I stumbled into an error I didn't expect:
java.lang.NoClassDefFoundError: com/company/application/utils
This is what I did to get this far:
1. Created an empty Web Dynpro DC (DC1), to be used as a utilities library.
2. Added a Java class to the webdynpro project.
3. Added the class to a public part of type compilation.
4. Created a second Web Dynpro DC (DC2), which is supposed to consume the class from DC1.
5. Added a DC-usage relation, so that DC1 is in DC2's used DCs. In this usage-relation built-time and run-time were checked
5. Used DC1's class in DC2's component controller
6. Built both DCs and deployed them
7. Ran the application in DC2.
When I run the application, the application dumps a stack trace at the moment that and object is created based on the class in DC1.
Any idea how to get this working?

Vincenzo, here is the real error message:
java.lang.IllegalAccessError: tried to access method nl.phoqus.pataut.Guid.getGuidString()Ljava/lang/String; from class nl.phoqus.pataut.PatientAuthorization
I have inserted a very simple GUID generator that I used in a previous project. Please find the class file below:
package nl.phoqus.pataut;
import java.util.Random;
public class Guid {
     private static Guid guidFactory = new Guid();
     static Random random = new Random();
      * Allow global replacement of the GUID generator. Applications
      * wishing to install their own GUID generators should sub-class
      * Guid, override the getGuid() method, and use this method to
      * install their generator.
     public static void
     setGuidImpl(Guid factory) {
     guidFactory = factory;
      * Return a GUID as a string.
     public static String getString() {
     return guidFactory.getGuidString();
      * Return a GUID as a string. This is completely arbitrary, and
      * returns the hexification of a random value followed by a
      * timestamp.
     protected String getGuidString() {
        long rand = (random.nextLong() & 0x7FFFFFFFFFFFFFFFL) | 0x4000000000000000L;
        return Long.toString(rand, 32) + Long.toString(System.currentTimeMillis()&0xFFFFFFFFFFFFFL, 32);
I'm calling the class using the following statements from the component controller of DC2:
Guid x = new Guid();
String y = x.getGuidString();
The component controller resides in package package nl.phoqus.pataut.
Would that be the problem?

How to load a java class when application is at first time browsed.

How can i load a simple java class on application startup.
For servlet it could be done using "load on startup" tag in web.xml

Adding a java class code in BPEL 11g

Hi Friends ,
i m doing one simple example of calling a java class from bpel ,
1. first i created a java class
2. After that in my project i imported the jar file of the same class , and i am using JavaEmbedding
for creating one object of that class and calling one method which return me the string result and finally i am setting the result in bpel variable.
the application is build successfull but when i am deploying it i am getting following error

please tell me what is the problem.

You have to use the below value there.
+2. After that in my project i imported the jar file of the same class ,+
There are 2 things, if you are not going to reuse the same code, its better to use Java Embedded component.
If you are going to reuse the same methods from the class then it make sense to import as jar file and use it.
Thanks,
Vijay

Container Object in Java Class

Hello ,
I have a Mapping program using java class type (Java SAX in this case). I need to access some Runtime constants and the mapping trace object.
In message mapping is simple. We can use the container object that is pass to a UDF and the GlobalContainer Object.
But how can I access the Runtime constants and mapping trace without a container object ?.
Any ideas...?
Thanks in advance.
Yuvan D.

in Your java mapping class
you should import import com.sap.aii.mapping.api.*;
public void execute(InputStream input, OutputStream output)
        throws StreamTransformationException {
        AbstractTrace trace = null;
        String RESULT = new String();
        trace =
            (AbstractTrace) param.get(
                StreamTransformationConstants.MAPPING_TRACE);
trace.addInfo(doc.toString());

Java Class Mapping Program in BPM process

I have a scenario where I'm receiving an IDOC I then use a JAVA mapping program in my first transformation step. Immediately following I have a switch step but there is not data in from the mapping program.
1) Receive Step
2) Transformation IDOC to Table using Java class
3) Switch step based on Table field value
Problem is there is no values in the table.
This java class was not developed within NetWeaver but was used in our old process. We simply imported the jar file for accessing our existing java classes. Is there something else we need to do to utilize our java modules within the BPM process?

Hi,
You must to have in the java class:
- You java have to be like:
import java.io.InputStream;
import java.io.OutputStream;
import java.util.Map;
import java.util.HashMap;
import com.sap.aii.mapping.api. AbstractTrace;
import com.sap.aii.mapping.api.StreamTransformation;
import com.sap.aii.mapping.api.StreamTransformationConstants;
public class JavaMapping implements StreamTransformation {
   private Map           param = null;
   private AbstractTrace trace = null;
   public void setParameter (Map param) {
      this.param = param;
      if (param == null) {
         this.param = new HashMap();
   public void execute(InputStream in, OutputStream out) {
try {
         trace = (AbstractTrace)param.get(
                   StreamTransformationConstants.MAPPING_TRACE );
         trace.addInfo(...);
         String receiverName = (String)param.get(
                   StreamTransformationConstants.RECEIVER_NAME);
The method execute take the InputStream with the XML source. The out (OutputStream) have to be an XML like the IDOC structure.
Regards.

Java class call from form

Hi
I'm doing single sign on via cookie and I able to get the cookie value and for decrypting I loaded java classes on the back end, When I called via form the jvm is crashing with some frm-92101 error.
First I want if anybody can help if I have to run any packages to execute java class from forms, I already created pl/sql wrapper class.
When I execute the function on the backend and got the decrypted value via pl/sql wrapper package but from forms the web servver is crashing, Can any body help.
Also where do I see the log file location.
Thanks in advance for the pro's for helping me
Thanks
Murthy

Can we call a workflow form a JSP and/or form a Java Class?

Is it possible to call a workflow form a JSP and/or form a Java Class?

Below is some xpress code I wrote once, used to dynamically lauch workflows from within a workflow. Since it basically uses java classes, you reuse these in your java program or jsp:
- create a new generic object
- call the setId, put, ... methods on it
- set the input variables for the workflow by putting them into the generic object
- call the checkinView method on a LighthouseContext object which launches your workflow.
If all you need is starting a workflow from a jsp, you might also want to take a look at the tasks/taskLaunch.jsp jsp. This is an out of the box jsp which allows launching of tasks. If I remember correctly you have to give an url parameter which specificies the name of task you want to start: tasks/taskLaunch.jsp?id=<workflow-name>

Hi All,
I Found the Solution.
The SAPinst tool was somehow not able to extracte the
J2EEINSTALL.SAR files from the JAVA Components DVD.
So I manually extracted the the file in the temporary install folder which the SAPinst creates in the /tmp filesystem (on LINUX by deafult) during the installation process.
The following command is used (I used this on Red Hat LINUX 5.2) to extract the J2EEINSTALL.SAR file:-
/sapmnt/SMD/exe/SAPCAR
-xvf /dump/SR4_Java_Components/D51033521/DATA_UNITS/JAVA_J2EE_OSINDEP_J2EE_INST/J2EEINSTALL.SAR
/sapmnt/SMD/exe/SAPCAR -->source directory of the file SAPCAR which is used to extarct CAR / SAR files on UNIX
/dump/SR4_Java_Components/D51033521/DATA_UNITS/JAVA_J2EE_OSINDEP_J2EE_INST/J2EEINSTALL.SAR--> destination dir. where the SAPinst tool will read and execute the file.
Rgds,

Intermedia Java Classes

I'm trying to use the Intermedia Java Classes for Servlets & JSPs (from http://technet.oracle.com/software/products/intermedia/htdocs/listing.htm#servelets_jsp) on a Sun machine with Apache/1.3.9 (Unix) ApacheJServ/1.1
It works quite fine, I'm just unable to upload any sort of image (the upload page gives me a java.lang.null pointer ex).
It becames funny because the same classes are perfectly working on my Win98 machine (on the same enviroment: Apache/1.3.19(Win32) ApacheJServ/1.1.2)
Anyone had a suggestion for me?
Thanks in advance.
Andrea
P.S. Please send any answer also to [email protected]
Thanks again

Hi,
Someone else with a completely different configuration ran into what looks to be the same problem you are experiencing. As there is no obvious reason for this error, I posted some suggestions for modifications to the sample application to try to track this down. Please check the following URL for information on what to change and where: http://technet.oracle.com:89/ubb/Forum27/HTML/001043.html
Using the trace information from the log file, hopefully, we should be able to see what's happening.
Other pieces of information that would help would be the JDK version you are using, plus the stack traceback from log file, to ensure that the problems are the same.
Regards,
Simon

Where does the java classes go?

I normally use IntelliJ which automatically puts the java class and the jsp where they are meant to go.
Can some help me.
Can someone please tell me where to put the java class, i have put the jsp pages in the webapps\ROOT but where does the java classes go?

sorry being stupid i do that sorry,
If i change the class to type (as someone said in a previous post)That would only work if you already put the bean in the session scope.
Did you try what PaulOckford wrote?

org.apache.jasper.JasperException: Unable to compile class for JSP:
An error occurred at line: 6 in the generated java file
Only a type can be imported. com.database.contactDB resolves to a packageDo you have a package structure that looks like this:
com
com/database/ <-- This is where contactDB.class is located
com/database/contactDB/
Because that is what the compiler is saying. Though it may be thrown off by case (see below)
P.S. If you use the jsp:useBean you do not need the import statement which appears to be where the error occurs. (One of the things that makes JSPs so hard to debug is the fact that the error line in the generated java file as referenced above is never the same as the line in the JSP file).

An error occurred at line: 3 in the jsp file: /login.jsp
database.contactDB cannot be resolved to a type
1: <%@ page import="com.database.contactDB" %>
2:
3: <jsp:useBean id='db'
4: scope='session'
5: type='database.contactDB'/>
6: <html>
And to be ultra clear - you did compile contactDB from a .java file to a .class file, and the class is called contactDB and not ContactDB correct? The class name is case sensitive and should be the exact same case in the useBean and import statements as in the real class name.
