Invalid java class problem

Hi , I have found this invalid java class in my schema portal30 : 3334f18_HttpProviderDispatche
In which way can I recompile it , or eventually change it with a new one ?
Thanks
Max

hi,
Go to your portal navigator and try compiling the class. If you get compilation errors,you can load that class to your database using loadjava utility.

Put all of them in one jar.
Then load the single jar.

Importing Java class problem!

Hello
I have problem by Importing java class into form. When I select in Forms Builder from menu: Programs/Import Java Classes it returns error: PDE-UJI001 JVM not able to create!
Can someone know what I must do to fix that problem?
Thanks, Chrity

It is a shame because it, probably, contains no special 1.5 new instruction at all.
Maybe it would be possible to try replacing the current JDK/JRE of your <ORACLE_HOME>/jdk installation after a safe backup of course.
You probably have a very little chance that it works, and it also won't be supported.

INVALID java classes

Earliar I posted a question looking for help with
deployment/redeployment that suddenly when bad and after some investigation I noticed that a high percentage of my Java classes under Oracle/HTTPClient are invalid.
This can't be normal, what steps should I take to correct
this

I don't have a good answer, however you might want to try this question on the Database JVM forum here: Java in the Oracle Database

Accessing MS Sql Server with Java classes - problem connecting to socket

I found an example at this location which uses java classes to connected to MS Sql Server.
http://search400.techtarget.com/tip/1,289483,sid3_gci1065992,00.html
--bummer - it is a login location - so I will include the article
Anyway, the example is using Websphere, but I am still on Jbuilder (will get wsad soon). So I planted the classes from the example in
C:\Borland\JBuilder\jkd1.4\jre\lib\ext\...the classes
Then I copied the code from the example to my jpx project and got an error that it could not connect to the socket. The only thing I changed in the code was the connection string:
--original string from example:
Connection connection = DriverManager.getConnection("jdbc:microsoft:sqlserver://1433", "");
I was getting an error with the 2 argument version of DriverManager - and the second argument here was empty (properties argument). Here was my connection string:
Connection connection = DriverManager.getConnection("jdbc:microsoft:sqlserver://Myserver:1433;User=sa;Password=");
I am only using the 1 argument version of DriverManager. Note that the password=" is blank because my RnD workstation is standalone - no one accesses the sql server except me - so no password. I also left out the last semicolon I noticed. Any suggestions appreciated how I could fix this.
Thanks

Sample code: Accessing MS SQL Server database from the iSeries
Eitan Rosenberg

Rating: --- (out of 5)
Nowadays with the help of Java the iSeries can be integrated with other databases quite easy. This tip shows you how. The code included here uses the free Microsoft driver that can be downloaded from here. (SQL Server 2000 Driver for JDBC Service Pack 3)
If your SQL server does not include the Northwind Sample Database you can find it here.
http://www.microsoft.com/downloads/details.aspx?familyid=07287b11-0502-461a-b138-2aa54bfdc03a&displaylang=en
The download contains the following files:
msbase.jar
mssqlserver.jar
msutil.jar
Those files needs to be copied to the iSeries directories (/home/r_eitan/ExternalJARs).
Here's the directory structure (on the iSeries) for this sample:
/home/r_eitan/ExternalJARs - Microsoft files (msbase.jar,mssqlserver.jar,msutil.jar)
/home/r_eitan/JdbcTest02 - My code (Main.java,Main.class)
The Java code
import java.sql.*;
import java.io.*;
class Main {
* Connect to Microsoft SQL server and download file northWind.products as tab
* seperated file. (products.txt)
public static void main(String args[]) {
try {
PrintStream outPut = new PrintStream(new BufferedOutputStream(new FileOutputStream("products.txt")));
Class.forName("com.microsoft.jdbc.sqlserver.SQLServerDriver");
//Connection connection = DriverManager.getConnection("jdbc:microsoft:sqlserver://1433", "");
Connection connection = DriverManager.getConnection("jdbc:microsoft:sqlserver://Myserver:1433;User=sa;Password=");
System.out.println("Connection Done");
connection.setCatalog("northWind");
String sqlCmdString = "select * from products";
Statement statement = connection.createStatement();
ResultSet resultSet = statement.executeQuery(sqlCmdString);
ResultSetMetaData resultSetMetaData = resultSet.getMetaData();
int columnCount = resultSetMetaData.getColumnCount();
// Iterate throught the rows in resultSet and
// output the columns for each row.
while (resultSet.next()) {
for (int index = 1; index <=columnCount; ++index)
String value;
switch(resultSetMetaData.getColumnType(index))
case 2 :
case 3 :
value = resultSet.getString(index);
break;
default :
value = """ + resultSet.getString(index) + """;
break;
outPut.print(value + (index < columnCount ? "t" : ""));
outPut.println();
outPut.close();
resultSet.close();
connection.close();
System.out.println("Done");
catch (SQLException exception)
exception.printStackTrace();

My guess is that the server's host name isn't right. It necessarily (or even usually) the "windows name" of the computer. Try with the numeric IP address instead (type "ipconfig" to see it).
First aid check list for "connection refused":
- Check host name in connect string.
- Check port number in connect string.
- Try numeric IP address of server host in connect string, in case name server is hosed.
- Are there any firewalls between client and server blocking the port.
- Check that the db server is running.
- Check that the db server is listening to the port. On the server, try: "telnet localhost the-port-number". Or "netstat -an", there should be a listening entry for the port.
- Try "telnet serverhost the-port-number" from the client, to see if firewalls are blocking it.
- If "telnet" fails: try it with the numeric ip address.
- If "telnet" fails: does it fail immediately or after an obvious timeout? How long is the timeout?
- Does the server respond to "ping serverhost" or "telnet serverhost" or "ssh serverhost"?

//here i need to pass some parameters to java class stored in my database,
something like:

How to download a java class from database to file system

Hi All,
We have one invalid java class in database. We need to verify what is the functionality of this class. So we planned to download this class to file system. Then we need decompile it to source. But we are not able to identify the right command to download the java class from database.
Please suggest me if any possible ways to acheive this.
Thanks in advance....

Problem with servicegen and how to convert java classes to webservices

I am a beginner and am trying to convert all my java code into webservices,I have
a java class Test.java and number of other third party libraries and my own java
files that are reffered in Test.java. I want to expose the public methods in Test.java
as webservices.
the serivegen part of My build.xml is as below
<servicegen
destEar="${APPLICATIONS}/${ear_file}"
warName="${war_file}">
<service
javaClassComponents="com.verizon.Test"
targetNamespace="${namespace}"
serviceName="Test"
serviceURI="/Test"
generateTypes="True"
expandMethods="True">
</service>
<classpath>
<pathelement path="${build}"/>
<pathelement path="${java.class.path}"/>
</classpath>
</servicegen>
When i run ant it complains:
[servicegen] weblogic.xml.schema.binding.BindingException: Invalid class received:
interface org.apache.crimson.tree.ElementFactory loaded from file:/apps/opt/crimson.jar!/org/apache/crimson/tree/ElementFactory.class.
All classes that will be serialized or deserialized must be non-interface, non-abstract
classes that provide a public default constructor
I have no clue,Why is Servicegen introspecting the third party class file also?I
just need the public methods in Test.java exposed and Test.java will just use
the third party library.
also,is there a way to tell servicegen to include all these java files X,Y,Z to
the war file/ear files but expose only the public methods of X in the WSDL.
Please help
thanks
Suresh

Hi Bruce,
Thanks very much for the insight u provided.Yes one of my public methods was returning
a element factory.
But let me ask my question this way:
Is there a way to tell servicegen to take only the specified public methods in
a class to make them as webservices?
by default servicegen is taking all the public methods..,i workaround i found
is to deploy the webservice manually by writing the web-services.xml to include
only the required public methods.
thanks

Bruce Stephens <[email protected]> wrote:
Hi Suresh,
Does your Test.java have a public method that returns the element
factory of an XML document, like "public ElementFactory
getElementFactory ();" or such?
If so, you may want to check out the supported build-in and non-built-in
data types:
http://edocs.bea.com/wls/docs81/webserv/assemble.html#1060696
Concerning your last question, you can use the excludeEJBs, includeEJBs
(in combination with the ejbJar attribute) to specify which non-built-in
data type components should be generated. Or if you use the
javaClassComponents then simply use a comma separated list of class
names.
Hope this helps,
Bruce

Web Service From Java class, serialization problem

Hi,
I want to create Web Service from Java class, I made java project, generated web service from it, create web service archive project and deployed it to WAS 6.40.
My class have 2 methods,
public int add(int a, int b);
public MyResponse doSomthing(MyRequest req);
I can succesfully call add method from Web Service Navigator, it works fine but when I call doSomthing methods I get the following error:
<b>
Deserializing fails. Nested message: XML Deserialization Error. Result class [com.mycomp.sap_tech.ws.MyRequest] does not have property [Amount] of type [java.lang.String]. It is required to load XML..
</b>
Any ideas how to resolve it?
P.S. MyRequest class is exposed throw VI, has default constractor and public getters and setters for all properties. It implements Serializable as well. Any guesses?
Thanks in advance,
Victor.

Hi Bhavik, thanks for response.
as I already mentioned it implements Serializable, so it is not the problem.
Thanks Avi but it didn't helps iether

XSLT mapping calls Java class, with hardcoded values-problem at Transport

Hi All,
I know the subject may be misguiding, but i need some suggestions how to handle the following scenario.
From my XSLT mapping, i am calling a java function which performs a data connection to an oracle database and then returns some values, whcih i have mapped in the mapping.
The problem is, i have hardcoded the Connection parameters....
and now that we transport these objects to production, the connection parameters will change.
I thought of two solutions
1) i create a new java class for Production system
2) i define the parameters as input arguemnts to my method, whcih is called from XSLT mapping
But in both cases, if theres any chg in future, there will a dependancy on one of the objects to be changed and sent again.
What is the suggested way? is there nothing like a property file(like in EP), where you define dependant parameters...and the file is only changed.
XI Gurus, please suggest me the correct way to handle.....
Thanks a lot.
Mona

Mona,
This is what i do..
1) Parametrize ur current calling class,
2) define a separate class called dbConnect.java there, you have all your parameters that way when there is a change your main program is untouched, and you just need to change the dbconnect.
The call from your current class will be just like
dbConnect.Runsql("sql as a string");
the runSql can then internally call
dbConnect().connect(); //that should do the connection opening.
then create a prepared statement from your string input and call the db.......
this is the implementation that would be best suited for your scenario, you can further parametrize the method to where you can add the database params from the calling xml..so all that needs to be done when the machine is changed or any param is changed is ..modify the xml........not too bad was that.....

Problems Creating a Java Class using a webservice with certificate

I already add the certificate using java control panel > Security > Certificates. When testing i get the following error: IOException (java.io.IOException: subject key, Unknown key spec)
I think I need to define the certificate in my class, but i'm having a lots of trouble with the samples that i found over the internet, nothing works and i'm running out of time.

Hi Deepak,
Could you please let us know upto which line your code is going safe. Try printing the value in the structure before you send that to the method GetUGEntity().
I am not too sure that would be a problem. But I have faced a problem like this, wherein I tried to access a structure for which I have not allocated memory and hence got exception because of that.
Since your JNI code seems to be error free, I got doubt on your C part. Sorry.

Problem in finding java class file

I am writting an application using servlets , JSP and a simple java classfile. The simple java class file is for connection pool and the name of connection pool class is DBConnectionManager . I am using JavaWebserver2.0 and I have placed this class file in .\JavaWebserver2.0\classes
I am placing my servlets in .\JavaWebserver2.0\servlets folder. Since I am using wfm package so my servlets are placed in .\JavaWebserver2.0\servlets\wfm .
The problem is with compiling the servlet placed in wfm folder . I get the following error:-
TestServlet.java:11:cannot resolve symbol
symbol: class DBConnectionManager
location: class wfm.TestServlet
However when I try to compile this class in servlets folder and remove the package statement from the source file, it compiles and works very fine. I am having lot of confusion as the class DBConnectionManager is in classpath but even then compiler gives error. The same class when placed in servlets folder and package statement is removed works very fine.
Kindly help.

Hi,
Is the DBConnectionManager class declared public?
Does the TestServlet import the package that contains the DBConnectionManager?
This is all I can come up with, with the current information.
Cheers,

Problems with data controls from java classes in JSF pages.

Hi! We have a problem in our Application that we are developing with JSF pages using Data Controls generated from facades java classes. When we running a page in debug mode and the page are loading, if we insert a breakpoint in the first line of method referenced in the data control, the execution enter two times in the method, and this is a problem for us. How to solve this?
We are using JDeveloper 11.1.1.2 with ADF faces.

You might need to play around with the refresh property of the action binding.

thank you for your help

thx for the reply
i did try to load the classes in the database but i seem to have a problem somewhere
