Java.lang.NoSuchMethodError: java.lang.Float: method parseFloat(Ljava/lang/
java.lang.NoSuchMethodError: java.lang.Float: method parseFloat(Ljava/lang/String;)F not found
WHAT WOULD MAKE THIS HAPPEN. THIS SEEMS TO WORK IN JDK1.3.1 BUT NOT IN BLACKDOWN 1.1.3_V3
THIS IS MY CODE:
try{
DecimalFormat dfp = new DecimalFormat( "0.00" );
if(!Price.equals("")) {
float MyFloat = Float.parseFloat(Price);
Price = dfp.format(MyFloat);
}catch(NumberFormatException nfe){
PriceValid = 1;
This error says:
- There is no method called "parseFloat" that receives a String as parameter in class java.lang.Float.
Look the method "parseFloat" at the class java.lang.Float!!

I would like to retrieve data from Oracle8.0.5 using sqlj.
i tried:
<%@page language="sqlj
import= sqlj.runtime.ref.DefaultContext,oracle.sqlj.runtime.Oracle"%>
and i've got the error:
java.lang.NoSuchMethodError: sqlj.tools.Sqlj: "method resetStaticVariables()V not found"
someone helps?
thanxThis uses a feature which is only found in post 8.1.6.1 versions of Oracle SQLJ. You have two choices:
(1) Download ojsp 1.0.0.6.1 or later from OTN. This contains an updated SQLJ version.
(2) Or wait for the SQLJ 8.1.7 release (or later) in the next couple of weeks.

After using jexegen from microsoft to make EXE. I receive this error when i execute the my EXE :
java.lang.NoSuchMethodError: java/util/Vector method revove...
Any body know why?
If i execute from JBuilder i have no problem!hi, i don't have much experience with M$ java products, but as far as i remember, M$ java stopped developping since jdk 1.1.4 (or 1.1.7).
maybe that's the reason for throwing this exception. if you want to "exe" your class-file, try JToExe.

I thought that the method in question was the getTextContext() method. ?
org.w3c.dom.Element.getTextContent()Ljava/lang/String
This is the method that contains the line in question(line 184 is last line):
public ArrayList getNodeList()
ArrayList arraylist = new ArrayList();
try
String serviceHostPort = null;
Document document = this.getDocument();
if(file.exists())
NodeList serviceName = document.getElementsByTagName("ServiceName");
NodeList serviceHost = document.getElementsByTagName("ServiceHost");
NodeList servicePort = document.getElementsByTagName("ServicePort");
if(serviceName.getLength() > 0)
for(int i=0;i<serviceName.getLength();i++)
Element serviceNameElement = (Element) serviceName.item(i); //CREATE THE SERVICE NAME ELEMENT
String serviceNameString = serviceNameElement.getTextContent(); //CREATE THE SERVICE NAME CONTENT THIS IS THE LINE IN QUESTION Thanks! -
Hello to all
I hope it is right forum for my question
I have found for error I get in Directprint this following:
When you migrate to the latest Forms version (10.1.2.3 or 11) and try using a JavaBean created with an older Forms version, you can get the following error, at runtime, in the Java Console:
Exception in thread "thread applet-oracle.forms.engine.Main-1" java.lang.NoSuchMethodError: oracle.forms.handler.IHandler.getApplet()Ljava/applet/Applet
The reason is you try to use a Java Bean compiled with an older Forms JAR file, like f90all.jar.
So, to correct the issue, you have to change the Java code then re-create the JAR file:
private Main formsMain = null;
Replace:
formsMain = (Main) handler.getApplet();
by:
// getting the Forms Main class
try{
Method method = handler.getClass()
.getMethod("getApplet", new Class[0]);
Object applet = method.invoke(handler, new Object[0]);
if (applet instanceof Main) {
formsMain = (Main)applet;
}catch(Exception ex) {;}
Then create and deploy the new JAR file to your /forms/Java folder.
My problem is
But I am very poor in java code, could you guide me to do what that article said, or pointing me where find instruction how do this following

Java.sql.Blob method setBinaryStream?
Hi,
I've been trying to use the java.sql.Blob methods instead of the "Oracle Extensions" so that people w/o Oracle (using MySQL etc.) can still use my code.
Problem: trying to get the OutputStream to write to the Blob. As of JDK1.4, java.sql.Blob has a method to do this, setBinaryStream. Unfortunately, calling this in Oracle JDBC (tried it in both thin and OCI version) throws an SQLException (Unsupported feature).
Sample code:
//Assume we already have a connection to the database, over either OCI or thin.
//Assume a Statement stmt created from the connection.
//Assume a table BlobTable with 2 fields : id (number) and data (blob).
public void uploadBlob(byte [] theBytes){
try{
stmt.executeUpdate("INSERT INTO BlobTable (id, data) VALUES (1,empty_blob())");
ResultSet rs = stmt.executeQuery("SELECT data FROM BlobTable WHERE id=1 FOR UPDATE");
if (rs.next()){
java.sql.Blob blob=rs.getBlob(1);
OutputStream out=blob.setBinaryStream(0);
//Next line never printed - error thrown.
System.out.println("Got Stream");
catch(Exception e){e.printStackTrace();}
//End code
Am I doing something wrong? Or is there simply no way to write to a Blob without using the extensions?
None of the docs (examples, guides, etc) make any mention of this, although the JDBC dev guide does mention that the similar method in PreparedStmt only works over OCI.
Thanks,
DanHi lancea,
It's been a while since this thread was active, but I have a related question.
Is there a comprehensive list of changes between JDBC 3 and JDBC 4 that makes application not work any more, such as this setBinaryStream issue or the CallableStatement/Named parameters issue that we stumbled upon. We would like to address these issues proactively and not find out about them in production, since we're upgrading from jdk1.4 to jdk6. Oracle has provided us with their changes regarding database versions, but have been less forthcoming with JDBC spec version changes.
Thanks in advance,

Call Java Class and Methods from ABAP
Hi
I install de JCo, But how i can call java class and methods from ABAP?. somebody has an example?
The tutorial say that's is possible, but don't explain how do that?
Thanks.
Angel G. HurtadoIf you need only simple java program, you do not need to install JCo. The following codes can call java class.
DATA: COMMAND TYPE STRING VALUE 'C:\j2sdk1.4.2_08\bin\java',
DIR TYPE STRING VALUE D:\eclipse\workspace',
PARAMETER TYPE STRING VALUE 'Helloworld'. "here the name of your java program
CALL METHOD CL_GUI_FRONTEND_SERVICES=>EXECUTE
EXPORTING
APPLICATION = COMMAND
PARAMETER = PARAMETER
DEFAULT_DIRECTORY = DIR
MAXIMIZED =
MINIMIZED = 'X' "If you need the DOS window to be minimized
EXCEPTIONS
CNTL_ERROR = 1
ERROR_NO_GUI = 2
BAD_PARAMETER = 3
FILE_NOT_FOUND = 4
PATH_NOT_FOUND = 5
FILE_EXTENSION_UNKNOWN = 6
ERROR_EXECUTE_FAILED = 7
OTHERS = 8.
Tell me if it works.

Why java allow start() method only once for a thread
Hi ,
Why java allows start method only once for thread . suppose
Thread t = new Thread();
t.start();
say at later stage if again we call t.start() IllegalStateException is thrown , even though isAlive method returns false.
Hence the question , why start() method is allowed only once.If you need start a thread , we need to create a new instance.Really. Why do you think that? Do you have any evidence? It is one of the first things I would think of, personally.Considering that the Thread API doesn't allow you to specify a stack address (only stack size), I think it demonstrates they wanted to remove that capability from their Thread API all together. That missing "capability" makes me believe they want me to believe it's not something I need to worry about when using their API... I think the exact semantics of the Thread class and its methods were driven by how to make it most understandable and usable for their customers. I'm certain this issue was one of many that was given considerable thought during the design and implementation of the JVM and the underlying runtime classes.
Do I have any evidence? No. But if you can point me at some first-hand information on this, I'd love to read it. Most of what I've found is second or third hand accounts. (and I mean that sincerely, not as a smart-ass remark or rebuke of your comments).
On the one hand you seem to think the Java API designers are idiots, on the other hand you think that they should be. I can't make it out.I thought my position was that the Java developers were talented enough to implement platform in whatever way their API called for; hence, the designers made a choice about how they wanted their API to be used by their customers. They decided which capabilities they wanted to include or exclude, and created an API that was consistent with their vision for this technology. While I'm certain technical limitations had an effect on the API design, I certainly don't think the API was dictated by the them.
I think the current design of the Java Thread API was a reflection of their vision to make Threading easier and more accessible to Joe Programmer, not limitations in the implementation. I never said it was wrong or that I could do better... I just said I think they could have done something different if they decided it would have made for a better customer experience. But hey, maybe I'm wrong. -
