Any idea what needs to be included in the CLASSPATh for resolving this error. I am running the program on Solaris 2.8
Java Version is as follows
hostname] java -version
java version "1.4.0_03"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.0_03-b04)
Java HotSpot(TM) Client VM (build 1.4.0_03-b04, mixed mode)
Would appreciate any help on this problem..Have been stuck with this for a few days :-((
TIA
Femy

That means u need to have the class or jar files corresponding to
org/acplt/oncrpc/XdrAble
in your jre. giving CLASSPATH helps only for sdk compilation. and with newer versions of jre, even the /bin/jre command is not found. so it is not clear how to install new class or jar files with jre. let sombody who knows enligthen on this

Java class files not found error in jsp sub-directories

Hello:
I have a web-application that is setup in the following way:
index.jsp
test\index1.jsp
WEB-INF\classes\test.class
Both jsp pages index.jsp and index1.jsp uses the test.class in the WEB-INF\classes directory.
The index.jsp page works fine.
The test\index1.jsp gives me a "cannot resolve symbol" error. Error shown below:
[jsp src:line #:19]
cannot resolve symbol symbol : class test location: class test.index1 test ts = new test("hello");
Any help at all is appreciated.
Thanks,
Benny

Hello Qiang:
Thanks a lot for replying, and sorry for the delay in replying back to you. I have been searching the forums for a while and have yet to find anyone else with a similar problem. And yes, it is kinda wierd.
But, anyways, I checked the java version from the windows command line as follows and it is using version 1.4.2:
java -version
java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)
Also, here are the contents of my test.class file:
public class test
private String t = null;
public test(String t1)
setTest(t1);
public void setTest(String t1)
 t = t1;
public String getTest()
 return t;
Here are the contents of my index.jsp file:
 hello 
<%
String test_str = null;
test ts = new test("Hello from the main jsp directory");
test_str = ts.getTest();
%>
 test_str is: <%=test_str%>
Click here to test your jsp index1.jsp file in the test sub-directory
Here are the results from this jsp page:
hello
test_str is: Hello from the main jsp directory
Click here to test your jsp index1.jsp file in the test sub-directory
Here are the contents from the test/index1.jsp file:
 hello from test sub-directory 
<%
String test_str = null;
test ts = new test("Hello from the jsp test sub-directory");
test_str = ts.getTest();
%>
 test_str is: <%=test_str%>
And here is what happens when I try to go to the test/index1.jsp page:
Request URI:/benny_test/test/index1.jsp
Exception:
OracleJSP:oracle.jsp.provider.JspCompileException:
Errors compiling:C:\OC4J\j2ee\home\application-deployments\default\benny_test\persistence\_pages\_test\_index1.java

47
 [jsp src:line #:5]
cannot resolve symbol symbol : class test location: class test.index1 test ts = new test("Hello from the jsp test sub-directory");
I will try putting it in a package like you said and see if that helps. Also, do you see a similar issue in your environment.
Anyways, thanks for all your help. Hope to hear from you soon.
Thanks,

Help with "Java class is not found" error

Hi,
I created my java program in a window environment, ran the program to a command line and it works.
I then put my jar file along with the other dependent jar in unix, I then run the command again and it's complaining that it cannot find the class file from the dependent jar. The class file does exist in the jar and also when I run "java" command I make sure that the jar was part of the classpath.
My command line looks like this:
$PS_JRE/bin/java -jar -classpath $CLASSPATH/jxl.jar jexcel.jar
I'm at a loss. Any advice would be greatly appreciated.
Thank you,
Giovanni

Well, I guess I got it working now.
The jxl.jar file I was using was compiled with 1.6 The unix server I was compiling on is 1.5.
Since I can't install a new version of java I was lucky enough to find a version of that api that was compiled with 1.5.
Now I'm all ok.

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,
Abhijeet K

Hello,
Please check the JVM-settings as per note
1024539 (including the environment-variables and APARS).
For some reason the 'migmon.jar' - file can no longer
be found in your installation directory
It might be sufficient to copy the archive 'MIGMON.SAR' from your
master-cd (subdirectory IM_AIX_PPC64/COMMON/INSTALL) to your
installation directory and extract the archive there by 'SAPCAR -xvf
If the problem persists
apply the latest patch as per note

"The java class is not found:" post clone

Hi.
I've just cloned an 11.5.10.2 environment from one AIX5.2 server running 9.2.0.7 to another server at the same AIX and RDBMS level.
After running the clone steps, the application was automatically started and I was able to access it via Self Service, forms, run concurrent requests etc - in short, I had a working system.
Now, however, when I try to stop or start the application using adstrtal.sh/adstpall.sh, I hit the following:
"The java class is not found: oracle/apps/ad/autoconfig/ServiceControl
Check logfile /data/testcomn/admin/log/TEST_ireaix2/05011011.log for details"
On the command line, when I call the line the script is trying to execute:
/usr/java14/bin/java -classpath "${CLASSPATH}:${JAVA_TOP}:${FND_TOP}/java/3rdparty/stdalone/xmlparserv2.zip" oracle.apps.ad.autoconfig.ServiceControl -e /oracle/testappl/admin/TEST_ireaix2.xml -u apps/<PASS> -m 2 -l yadda –debug
I'm able to bypass this particular error and some of the application processes do start but not all of them and obviously I still have an underlying Java/environment issue.
Any suggestions gratefully received.

Overview of Leave --- CREATE OBJECT: The class was not found., error key:

Dear Gurus,
Iam facing this problem that, when i try to open the Leave Overview from the leave request screen. it gives the dump with message
CREATE OBJECT: The class was not found., error key: RFC_ERROR_SYSTEM_FAILURE
this also creates a dump in the back end.
The same dump is appearing when i try to view the Check Documents for the same employee from PTARQ.
Thanks in advance
Ramnath

Hi ,
please find the following solution .it will definitely work .
If you leave configuration is done.
There was an incorrect data in your system. To do these please follow following process.
delete this request using
PTARQ> Delete documents (RPTARQDBDEl)
Please read the report documentation before
deleting the request but it should be safe as it is
a development system.
Please delete this with the above information or delete all
the records for the approver.
After this,, there will be some incorrect workitem in approver inbox.
You need to clear that also by Tcode - SWWL.
ALSO check the leave request workflow of that employee and if there is any error workflow lying in the workflow delete the leave request (which was created with error) Note down the id initiater ( which had error) and in the Test Environment for Leave request (PTARQ) gave the PERNR and delete the documents ( give the id iniater in the document status ).
To check the error work flow go to SWIA and check for that Workflow (Leave) raised by the PERNR at that duration ( check in IT2001 for the duration) and give it here.
After deleting it check in the portal for the leave request if any error is occuring when trying to apply for leave.

SOAP oracle xml sql utility class definition not found error

I have created a java class that connects to database using JDBC runs an sql statement and produces xml using Oracle XML SQL Utility class. The java class works perfectly when I deploy it as a soap web service and try to run through SOAP server it gives a SOAP error oracle/xml/sql/query/OracleXML/Query [java.lang.NoClassDefFoundError].
Can anyone help please.
Thanks
Alina

Sounds like you have not included the xsu12.jar file in the server-side CLASSPATH.
This depends also on the xmlparserv2.jar and on the Oracle JDBC driver. Later versions
of XSU may also depend on the xdb.jar file, too.

Error(23,19): method getName(java.lang.String) not found in class javax.swi

Hi , when i try to run my program, i keep getting the error msg:
Error(23,19): method getName(java.lang.String) not found in class javax.swing.JTextField
I have checked the java API and it inherits from the awt.Component class and should be accessible via the jtextfield.
I have tried the following:
trying to initailise the JTextField at the start.
Using getName works if i use it within the loop after setting the name.
Does anybody know what i am doing wrong please?
public class clsMember extends JPanel implements ActionListener {
 private JButton jbtnLog;
 private String surname;
 private JTextField txtItem;
 public clsMember() {
 super(new SpringLayout());
 makeInterface();
 surname = txtItem.getName("Surname").toString();
private void makeInterface() {
 //code omitted
 for (int i = 0; i < numpairs; i++) {
 JLabel l = new JLabel(strLabels, JLabel.LEADING);
this.add(l);
//if the array item is salutation create a combobox
if (strLabels[i] == "Salutation") {
jcomSalutation = new JComboBox(strSalutation);
jcomSalutation.setSelectedIndex(0);
this.add(jcomSalutation);
} else {
txtItem = new JTextField(10);
l.setLabelFor(txtItem);
txtItem.setName(strLabels[i].replaceAll(" ", "")); //this is where the label is set and if i do a system.out it shows fine. getName works here too.
this.add(txtItem);
//code omitted

If i have a loop that creates the jtextfields such as
 txtItem = new JTextField(10);
 l.setLabelFor(txtItem);
 txtItem.setName(strLabels.replaceAll(" ", ""));
this.add(txtItem);How is it then possible to assign to a string the value of a *specific jtextfield*. Lets say that one of these JTextfields has the name surname.
How is it possible for me to writeString surname = surnamejtextfield.getText();

Dear Miciuli,
I found the definition for the circle in the canvas class and used it to creates circles ! Thank you for jaring my brain into thinking !

Ellipse2D.Double circle = new Ellipse2D.Double(xPos, 70, 30 , 30);
