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.

Execution problem a stored java class

Hi,
I loaded a java class ("ConvertisseurXMLPDF") in an oracle 8.1.7 database and in a specific schema "SCHEMA1".
I loaded it with the loadjava command included the -synonym and the -grant attributes to create the public synonym on this class and the grant execute to a role "ROLE1".
Problem :
I connect with a user "USER1" which is associated to the role "ROLE1" (so, he should have the execution privilege on the class) and
When I execute the procedure which launches the execution of the java class, I have the following error message :
java.lang.illegalAccessException
at java.lang.Class.newInstance0(Class.java)
at java.lang.Class.newInstance(Class.java)
at ConvertisseurXMLPDF.createParser(ConvertisseurXMLPDF.java:162)
at ConvertisseurXMLPDF.converssion(ConvertisseurXMLPDF.java:162)
It seems, it does not even achieve to instantiate the class!
What could be the reason of this problem?
Thanks in advance
bye

Make sure you have the following privileges:
grant javasyspriv to schema1;
grant javauserpriv to role1;

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.

Execution of a Java Class on a remote machine (RMI ??)

Hi guys,
I have an application in Java which, processes a local file and return some results. The local file is so huge (> 2Gb).
I need to process some distant (remote) files with this application. Firstly, I thought to make a FTP or HTTP connection to remote file and get an InputStream of that and give this InputStream as input to my application. But according to the size of file and transfer rate it's not a good solution may be a bad one.
So, I try to find a solution to send my application (Java Class) to remote machine and request its execution there. Like this, the application will execute locally on remote machine and then I just take the results via network.
I dont know exactly if it's possible or not. I think to RMI or COBRA techniques. But I dont know these methods at all. Does RMI let to send a java class (in fact some class which are dependent) to a remote machine and execute it there and take the results? If yes, I wonder what are the constraints and needs? specially in machine characteristics level?
Or any other solution to execute an Java code locally on a remote machine?
many thanks guys
Hassan

Thanks Pantony,
It's what I want to do. But as I saw to use RMI, wa have to have the remote objects (methods) on host. Then we can call them remotely.
It's nice solution.
BUT, I wonder if there is not possibility to have the remotes method on host side, can we, for example, copy automatically an executable version of application to host and then call it remotely? then take the results saved in a file on host.
If yes, so why RMI? why the remote objects?
And how we can execute a *.JAR (java executable) on a remote machine?
Many thanks
Hassan

Hi thanks for responding. Ok i did look through and it was opening some gui.

Any ideas?

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.

Tracing a java program execution

Hello. I would like to know which classes of a java archive (jar) are executed when i execute an application. Is there an easy utility to do this?
There's an application running on a server. I would like to know which class is called first when a tcp client is connection to the server...
Thank you for your help, it's very very important.
Wardem fury - Paris.

thank you. i thought that the java language had some specific modules to automatically trace a java program execution....
anyway, thank you.

XSLT Mapping with Java class not working in Integration Repository

Hi,
I have an XSLT mapping program with Java enhancement and I was able to successfully tested it in Stylus Studio. However, when I imported the Java class and the xslt program in Enterprise Service Builder and tested it, my program does not compile.
Here is the error message: "Transformer Configuration Exception occurred when loading XSLT mapping_temp.xsl; details: Could not compile stylesheet".
My java program is in a zip file containing SOAPHeaderHandler.java and SOAPHeaderhandler.class. My Java has a package com.nga.xslt.
Here is the declaration of my Java class in the XSLT: xmlns:javamap="java:com.nga.xslt.SOAPHeaderHandler"
It seems that it could not read the java class. Can you please advice what is wrong?

Hi ,
select XMLTOOLKIT option in Operation mapping and execute it.
I am not sure we can call java program in XSLT Program,but alternative is copy the code and use it in XSLT mapping it self,that means your XSLT program will become with JAVA extensions.
then in Operation mapping level select SAPXMLTOOL kit option and execute it. i hope it will work. if it is not working then you have deploy some JAXP files on server,because the way execution of XSLT Mpaping program got changed,like when eve you executing XSLT with extnasions( if you are not using XMLTOOL kit option) then you have to use latest version of JAXP.JDK files.

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 create java classes when multiple xsd files with same root element

Hi,
I got below error
12/08/09 16:26:38 BST: [ERROR] Error while parsing schema(s).Location []. 'resultClass' is already defined
12/08/09 16:26:38 BST: [ERROR] Error while parsing schema(s).Location []. (related to above error) the first definition appears here

I tried genarate java classes from multiple xsd files, but getting above error, here in .xsd file i have the <xe: element="resultClass"> in all .xsd files.
So I removed all .xsd files accept one, now genarated java classes correctly. but i want to genarte the java classes with diffrent names with out changing .xsd
Can you please tell me any one how to resolve this one......

prasad.nadendla

Gregory:
If you want to upload several Java classes in one script the solution is .sql file, for example:
set define ?
create or replace and compile java source named "my.Sleep" as
package my;
import java.lang.Thread;
public class Sleep {
public static void main(String []args) throws java.lang.InterruptedException {
if (args != null && args.length>0) {
int s = Integer.parseInt(args[0]);
Thread.sleep(s*1000);
} else
Thread.sleep(1000);
create or replace and compile java source named "my.App" as
package my;
public class App {
public static void main(String []args) throws java.lang.InterruptedException {
System.out.println(args[0]);
exit
Then the .sql file can be parsed using the SQLPlus, JDeveloper or SQLDeveloper tools.

How do I call a simple java class from a bpel process?

Hi.
In JDeveloper 10.1.4.3.0 I've created a simple java class that does an ftp get operation followed by an unzip. The class uses some 3rd part libraries (jars).
I want to use a simple bpel process to schedule a daily execution of this java class, and deploy it all to our SOA-server, - and was looking into using the <bpelx:exec> function.
The java class and the bpel process is all stored in the same JDeveloper project.
How do I put this together so that both my java class and the necessary jars are available to the bpel process?
I've looked into the JavaExecSample.bpel, and it's says something about "...the class com.otn.samples.javaexec.CreditCalculator is locally packaged with this BPEL process".
How do I do that?
Can I make it and test it all locally from my workstation (only JDeveloper installed, I guess there's nothing that can execute the bpel code?), or do I have to compile class etc (make war-file?) and deploy to SOA server (BPEL-INF/lib or classes?) before anything can be tested?
(I guess all this is simple, once you know how, but being a newbie to this I need a shove in the right direction :-)
Regards,
-Haakon-

To create a java class and dependent jars inside the BPEL process project you need to do the following:
1. Right click on your BPEL process project and select New and then Java Class from the Items.
2. Make the BPEL process project, JDeveloper would compile the java classes and add them into the BPEL suite case jar, see the output folder and check the BPEL suite case jar file for java classes and dependent jars.
You can test your Java classes from JDeveloper IDE, no need to deploy the classes on SOA server. When you make the BPEL project it compiles .bpel files and Java classes. You can test your classes once .bpel file and java classes compiled successfully.

Running a "heavy" program from within a java class

Dear Java programmers,
I 'm trying to run a software called surflex from within a java class, using the following java command:
Runtime.getRuntime().exec( new String[ { "/bin/bash", "docking_script_2.bash"} );
For convenience I've created the following simple bash script but for some strange reason surflex is not executed:
#!/bin/bash
surflex-dock-v211-linux.exe proto drug.mol2 receptor_hydro.mol2 p1;
surflex-dock-v211-linux.exe dock drug.mol2 p1-protomol.mol2 receptor_hydro.mol2 >& 1OHR_A_output.txt;
Can anybody help me on that (ignore the arguments, they are correctly set)? I'll try to find another, more generic example, but so far I've noticed that the same thing happens with unix grep command.
thanks,
Tom

I think if you want to invoke a bash shell and give it a command to execute, you need to do
/bin/bash -c commandrather than
/bin/bash commandAccordingly, your call to exec should look like
exec( new String[ { "/bin/bash", "-c" "docking_script_2.bash"} );Beyond, that, I'd suggest the following as general debugging tips and best practices:
* As the first line of the bash script, include a line that does something simple, like touch a file, so you can see if the script is executing at all.
* In Java, call Process.waitFor(). Its return value is the process' exit value.
* Make sure you're gobbling stdout and stderr from the process, and giving stdin any input it needs. You'll have to do this for the process to run correctly, and you can also use what you read from stdout and stderr to debug the execution of the process. [http://www.javaworld.com/javaworld/jw-12-2000/jw-1229-traps.html]
* You may wan to look into ProcessBuilder, rather than Runtime.exec. I haven't used it myself yet, but apparently it's supposed to be the preferred way to execute external processes.

PI 7.1 Enhancement pack 8: still error when referencing java class in xslt

Hi
I am getting an error in PI 7.1 EP 8 Repository when I try to use an xslt in which I make a reference to a java class. The error is:
Transformer Configuration Exception occurred when loading XSLT XCBL_invoice_stylesheet.xsl; details: Could not compile stylesheet
I use this xslt:
<xsl:template match="/" xmlns:util="dk.dongenergy.pi.mapping.Utilities_datetime">
          <html>
<B><xsl:text>Received: </xsl:text><xsl:value-of select="util:getCurrentDateTimeFormatted()"/>
I have imported the java archive successfully and it is working in XI 3.0 and it is working if I comment out the reference to the java class in the xslt.
the java class looks like this:
package dk.dongenergy.pi.mapping;
import java.text.SimpleDateFormat;
import java.util.Date;
public class Utilities_datetime {
*     public static String getCurrentDateTimeFormatted() {*
*          Date now = new Date();*
*          SimpleDateFormat formatter = new SimpleDateFormat("dd MMM yyyy HH:mm:ss");*
*         return formatter.format(now);*
We have applied enhancement pack 8 on PI 7.1 as suggewsted in this note, but that has not done the trick:
