Error while compiling java class (ora-29535 source requires recompilation)

Hello. I`m new with oracle and i`m having a problem with java classes. Few days ago i loaded java classes (loadjava) from jar file(biojava3-structure-3.0.2.jar) and compiled ( everything compiled with status valid). Now i`m writing my own class and i can`t import classes from biojava3. I`m getting error:
Projekt:7: cannot access org.biojava.bio.structure.Atom
bad class file: null
class file has wrong version 50.0, should be 49.0
Please remove or make sure it appears in the correct subdirectory of the classpath.
import org.biojava.bio.structure.Atom;
I have tryed to change jdk version in netbeans from 1.7 to 1.6. I created java class in sql plus That still not resolved my problem.
Please help me.

consider posting in Java forum instead of Database forum

Error while compile .Java to .class

I am new in java card. I have some problem when compile java card applet.
1. I installed j2sdk1.4.2_07 and java_card_kit- 2_2_2 to build a sample java card. I set the environment as:
@echo off
set JC_HOME=C:\java_card_kit-2_2_2-windows\java_card_kit-2_2_2
set JAVA_HOME=c:\j2sdk1.4.2_07
set PATH=.;%JC_HOME%\bin;%JAVA_HOME%\bin;%PATH%
I created a java applet and saved in C\STCard, and I use windows command to compile, the command is:
c:\java_card_kit-2_2_2-windows\java_card_kit-2_2_2\samples>javac -g -classpath c:\STCard;..\lib\api.jar;..lib\installer.jar c:\STCard\*.java
but the error is: "cannot access javacard.framework.APDU"
What am I wrong?
2. I use eclipse 3.3.2, eclipse jcde 0.1, java_card_kit-2_2_2, jdk1.6.0 to compile java card applet. The compilation from .java to .class was no problem, but from the .class to .cap has problem:
java com.sun.javacard.converter.Converter -config .\converter2.opt
error: stcard.STCard: unsupported class file format of version 50.0.
What should I do to convert from .class to .cap?
Thx all

Error while compiling java file using J2SE 1.5.0

Dear Sir,
I'm getting the following error while compiling the java file.The code is also given.
package test;
public class TestRowSet {
public TestRowSet() {
"TestRowSet.java": cannot access java.lang.Object,bad class file: D:\Program Files\Java\jdk1.5.0\jre\lib\rt.jar\java\lang\Object.class,class file has wrong version 49.0, should be 48.0,Please remove or make sure it appears in the correct subdirectory of the classpath. at line 4, column 1
Please help me out.
--Suketu Naik.

But I'm compiling within "Borland JBuilder 9.0". I've
set the JDK path of the current project to point to
the path of JDK 1.5.0 . I've also tried to compile at
command prompt with "javac". I'm getting the same
error of "Undefinedclassloader" with long StatckTrace.
I don't know anything about JBuilder either. If you use the command prompt and enter the full path to the 1.5 javac.exe then that will prove whether the issue is using an older javac or not. For example "c:\j2sdk1.5.0_01\bin\javac HelloWorld.java"

Error while compiling java file

Hi, im newby in java,
i was trying to compile java files, and after that i will use it in JSP as javabean.
I have 2 files already, the first file is a connection code, and its compiled successfully, it looks like this
i named this as ConnectionBean.java
package my_package;
import java.sql.*;
public class ConnectionBean {
     private Connection con;
     private static final String driver = "org.postgresql.Driver";
     private static final String url = "jdbc:postgresql://localhost:5432/PSQLDS";
     private static final String username = "postgres";
     private static final String password = "mypassword";
     public ConnectionBean() {
     public Connection logOn() {
          try {
               Class.forName(driver); con = DriverManager.getConnection(url, username, password); }
          catch(ClassNotFoundException e) {
               System.err.println("ConnectionBean: driver unavailable..."); con = null; }
          catch (SQLException e) {
               System.err.println("ConnectionBean: driver not loaded..."); con = null; }
          return con;
     public void logOff() {
          try {
               con.close(); }
          catch (Exception e) {
               e.printStackTrace(); }
as you can see above im using "package", and yes i have manage to put all my java files within the correct path (ROOT\WEB-INF\classes\my_package)
And also, i have test this class as javabean on JSP file and it works.
There for i continue to create the second java file, as a purpose to create a back engine for JSP. I use the same package as ConnectionBean.java, it looks like this
i named this as ListPageEngine.java
package my_package;
import java.beans.*;
import java.sql.*;
public class ListPageEngine {
     public static void main(String[] args) {
          ConnectionBean conBean = new ConnectionBean();}
on compiling process using command "javac ListPageEngine.java", i get this error message
ListPageEngine.java:11: cannot find symbol
symbol : class ConnectionBean
location: class my_package.ListPageEngine
ConnectionBean conBean = new ConnectionBean();}
^
ListPageEngine.java:11: cannot find symbol
symbol : class ConnectionBean
location: class my_package.ListPageEngine
ConnectionBean conBean = new ConnectionBean();}
^
2 errors
I think, i am pretty much sure that all my configuration (wheater its Apache TomCat, Environment Variable or PostgreSQL server) was good, as a prove, i was able to use ConnectionBean.class in my JSP file.
I susspect the problem is related with "package", seems i cannot use ConnectionBean class within ListPageEngine class when i use package.
For another information, i didn't install such thing as J2EE, i only install JDK 1.5, i also guess this might be the cause.
Right now im all stuck, i try to find thread which might be related with my problem but i failed to find it, most of them get the same answer by UncleSAM which are
Try the following forum (about JSP technology)
http://forum.java.sun.com/forum.jspa?forumID=45
JavaBeans spec contains nothing about JSP, but JSP spec describes using of beans.
i hope my question is clear so anyone who might have experience or clue with this problem might be able to help me.
Thanks before

finally folks, i found answer to my own problem hehehehe..
the problem is on the compiling command (javac ... my_file.java), i found that i need to add some parameter on the command to make it works.
This problem solved.

Error while importing java class into oracle forms 10g

Hi
I have generated a web service client using jdeveloper 10g. It consists of complex type methods. I am trying to import the class files using java importer in oracle form 10g. I am able import all of them successfully except one. That one is the main method. Please see the error and suggest me how to overcome this error.
Exception occurred: java.lang.NoClassDefFoundError: oracle/jdeveloper/webservices/runtime/WrappedDocLiteralStub
Thanks in advance

Do you see oracle/jdeveloper listed in "Import Java Classes" when you try to import?
If not, make sure you add C:\DevSuiteHome_1\jdev\lib\jdev.jar to FORMS_BUILDER_CLASSPATH in registry
Also excetion indicates: oracle/jdeveloper/webservices/runtime/WrappedDocLiteralStub
If you typing it - type: oracle.jdeveloper.webservices.runtime.WrappedDocLiteralStub

Error While Importing Java Classes

I have Forms 6i and when i am trying to import Java classes i am getting the following error
"PDE-UJI001 FAILED TO START THE JVM".
i think i have not set the path and classpath properly.i am having Windows 2000 server as my OS. please help me how to solve this problem

The Java Importer tool needs the JDK 1.2.2 to be installed on
the machine to run properly. This JDK can be downloaded from the
Sun web site at http://www.sun.com
If there is no JDK 1.2.2, the Java Importer tool cannot be started.
Either that or its not being found in the classpath.

If your directory structure looked like this, for example:
c
|_java
 |_applications
 |_com
 |_pgm1
 |_pgm2... Then back up to the 'applications' directory and compile as:
javac com\*.java
Run as:

I created custom VO and files in my local JDev and it is working properly.
I wanna migrate it to actual instance.So my question is is it mandatory to compile custom java file in application server or i can use same which i used in my local machine(windows)?

Suffering an complie error when trying to compile java class in EBS11i

Hi,
When I trying to compile java classes with which imported the HttpServletResponse class, will get the follow error message:
package javax.servlet does not exist
cannot resolve symbol
symbol : class HttpServletResponse
It seems the javax.servlet package is not included in the classpath. But I checked the $CLASSPATH, it seems no problem.
echo $CLASSPATH
/u02/applvis/viscomn/util/java/1.4/j2sdk1.4.2_04/lib/tools.jar:/u02/applvis/viscomn/util/java/1.4/j2sdk1.4.2_04/lib/dt.jar:/u02/applvis/viscomn/util/java/1.4/j2sdk1.4.2_04/jre/lib/charsets.jar:/u02/applvis/viscomn/util/java/1.4/j2sdk1.4.2_04/jre/lib/rt.jar:/u02/applvis/viscomn/java/appsborg2.zip:/u02/applvis/visora/8.0.6/forms60/java:/u02/applvis/viscomn/java
Does anyone know the reason?
environment: ebs 11i
Thanks&Regards,
Xiaofeng

resolved this issue.
1. Edit $APPL_TOP/admin/adovars.env file -
Add the following jar files to the AF_CLASSPATH line -
Full path of /...../iAS/Apache/Jsdk/lib/jsdk.jar
Full path of /...../iAS/Apache/Jserv/libexec/ApacheJServ.jar
2. Bounce the concurrent manager in order to have the changes take effect.

ORACLE error 1031 while importing java classes

Hello Guys,
We are seeing following errors while importing SYS/SYSTEM objects.
IMP-00017: following statement failed with ORACLE error 1031:
IMP-00003: ORACLE error 1031 encountered
IMP-00090: Unexpected DbmsJava error -1031 at step 6666 while creating JAVA CLASS "javax/swing/plaf/basic/BasicTreeUI$KeyHandl
er"
We are doing platform migration of Oracle Apps instance from Solaris to Linux using exp/imp.
These errors are same for numorous classfiles. Seems like some privileges are lacking but not sure what they are. If any of you had similar experiences before please share with us. We have an open P1 SR with Oracle running for almost 3 days but no solution yet ...
Thank you,
Aditya

Pl post your full versions of OS, EBS and database. Pl verify that you are following these MOS Docs

Error loading a java class to oracle db

hi,
my oracle server: 8i Enterprise Edition Release 8.1.7.0.0
i want to load a simple java class into my oracle server.
java source:
public class Ping
     java.lang.String server;
     public static void main(java.lang.String[] args)
          System.out.println(new Ping().runCmd(args[0]));
     public static java.lang.String runCmd(String cmd)
boolean result=false;
int timeout=5000;
try {
java.net.InetAddress byName=java.net.InetAddress.getByName(cmd);
               result=byName.isReachable(timeout);
catch(java.io.IOException e)
e.printStackTrace();
     java.lang.String retVal=java.lang.Boolean.toString(result);
          return retVal;
after compiling the java file. i'm using loadjava at dos prompt.
loadjava -user uname/pwd@db -resolve Ping.class
this command results in
ORA-29545: badly formed class:
loadjava: 1 errors
alternatively i had used a command
loadjava -user uname/pwd@db -noverify -resolve Ping.class
this command results in
Error while turning off verifier
ORA-29532: Java call terminated by uncaught Java exception: java.security.Ac
cessControlException: the Permission (oracle.aurora.security.JServerPermission V
erifier ) has not been granted by dbms_java.grant_permission to SchemaProtection
Domain(SMSPGS|PolicyTableProxy(SMSPGS))
ORA-29545: badly formed class:
loadjava: 2 errors
but user is having sufficient rights (javasyspriv)
what is wrong above, please help me.
regards,
s.mohamed asif

hi,
thanks for your response
Ping.class just checks whether the specified node is reachable or not.
result=byName.isReachable(timeout);
the jdk loaded in oracle DB is older one and the method above java.net.InetAddress.isReachable(java.lang.int) is available since
jdk 1.5
source:
public class Ping
java.lang.String server;
public static void main(java.lang.String[] args)
System.out.println(new Ping().runCmd(args[0]));
public static java.lang.String runCmd(String cmd)
boolean result=false;
int timeout=5000;
try {
java.net.InetAddress byName=java.net.InetAddress.getByName(cmd);
result=byName.isReachable(timeout);
catch(java.io.IOException e)
e.printStackTrace();
java.lang.String retVal=java.lang.Boolean.toString(result);
return retVal;
}how to load the new jdk set into existing oracle db server and replace the existing jdk.
what can be done to achieve this ?

s.mohamed asif
