NoSuchMethodError in EJBHomeImpl.findBy() methods

Hi All,
I've searched all past entries relating to java.lang.NoSuchMethodError, but most
responses have suggested mere typo errors or, at most, the presence of multiple
jars during deployment. I've checked that this is not what happens to my BMP,
but I still get the NoSuchMethodError in my EJBHomeImpl.findBy() method when the
generated code reaches the
weblogic.ejb.internal.MethodInfo __mi = findMethodInfo(__methodSig);
line.
I also ran the beanManaged example and it ran fine. I've done several rebuilds,
most involving cleaning out all compiled classes and jar related to my project.
I'm using Weblogic 5.1 SP8 on Windows NT 4 SP 4.
Any help would be appreciated.
Thanks,
Boogie

Hi Sean,
Simple solution.
Run a search in ur computer with the name of ur home interface's .class file.
That ll display all the places where ur home interface .class files are stored(there are certain folders in the server where is gets stored secretly.: - ) ).
Then go to individual location and delete the .class files.
make all the editions u have to in ur bean class and ur home interface.
compile using build again.Hope u achieve ur objective now. ; - )
Regards

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!!

Java.lang.NoSuchMethodError: sqlj.tools.Sqlj: method resetStaticVariables()V not foun

I would like to retrieve data from Oracle8.0.5 using sqlj.
i tried:
<%@page language="sqlj

and i've got the error:
java.lang.NoSuchMethodError: sqlj.tools.Sqlj: "method resetStaticVariables()V not found"
someone helps?
thanx

This 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.

FindBy method for reference entities

hi,
I have created an entitity(Relation) which contains references of other 2 entities(address, person).I have created findBy methods(FindByCity,FindByLastName,etc) in Relation entity for attributes in those refernce entities(Address-city,state)(Person-First name, Last Name). but while i'am testing these functions it says :
<b>ERROR. setFilter column(25): Undefined expression 'personRef_var.refObject.name'</b>
I'am not able to decipher this error message. can anyone help me about what could possibly be wrong in the code generated. the following is the code containing this reference :-
if ("addressRef".equals(attrName))
if (subAttrName == null)
   resQueryFilter.setCollectionType("com.sap.relation.besrv.relateaddperson.AddressRefVO");
                         resQueryFilter.setCollectionAttribute("addressRef");
                         resQueryFilter.setAttribute("addressRef_var.refObject.key");
else
     strParamName = subAttrName;
     dotIndex = strParamName.indexOf('.');
     attrName = (dotIndex == -1) ? strParamName : strParamName.substring(0, dotIndex);
     subAttrName = (dotIndex == -1) ? null : strParamName.substring(dotIndex + 1, strParamName.length());
     resQueryFilter = new com.sap.caf.rt.bol.util.IntQueryFilter((com.sap.caf.rt.bol.util.QueryFilter) qf);
                         resQueryFilter.setAttribute("addressRef_var.refObject." + strParamName);
} else if ("personRef".equals(attrName))
if (subAttrName == null)
{                         resQueryFilter.setCollectionType("com.sap.relation.besrv.relateaddperson.PersonRefVO");
                         resQueryFilter.setCollectionAttribute("personRef");
                         resQueryFilter.setAttribute("personRef_var.refObject.key");
else
     strParamName = subAttrName;
     dotIndex = strParamName.indexOf('.');
     attrName = (dotIndex == -1) ? strParamName : strParamName.substring(0, dotIndex);
     subAttrName = (dotIndex == -1) ? null : strParamName.substring(dotIndex + 1, strParamName.length());
     resQueryFilter = new com.sap.caf.rt.bol.util.IntQueryFilter((com.sap.caf.rt.bol.util.QueryFilter) qf);
     resQueryFilter.setAttribute("personRef_var.refObject." + strParamName);

Hi Pamita,
Generation is errorneous for related entities which do not have relations at all. This problem emerges when you searching by some specific attribute of related entity.
The following workarounds:
1. Create a fake relation for Person and Address entities. For example you can create relation from Person to Person.
2. Change generation template. I don't remember template name - it should be like ServiceBean.
the following fix in generated coding should work:
<code>
if ("addressRef".equals(attrName))
if (subAttrName == null)
resQueryFilter.setCollectionType("com.sap.relation.besrv.relateaddperson.AddressRefVO");
resQueryFilter.setCollectionAttribute("addressRef");
resQueryFilter.setAttribute("addressRef_var.refObject.key");
else
strParamName = subAttrName;
dotIndex = strParamName.indexOf('.');
attrName = (dotIndex == -1) ? strParamName : strParamName.substring(0, dotIndex);
subAttrName = (dotIndex == -1) ? null : strParamName.substring(dotIndex + 1, strParamName.length());
resQueryFilter = new com.sap.caf.rt.bol.util.IntQueryFilter((com.sap.caf.rt.bol.util.QueryFilter) qf);
resQueryFilter.setCollectionType("com.sap.relation.besrv.relateaddperson.AddressRefVO");
resQueryFilter.setCollectionAttribute("addressRef");
resQueryFilter.setAttribute("addressRef_var.refObject." + strParamName);
} else if ("personRef".equals(attrName))
if (subAttrName == null)
{ resQueryFilter.setCollectionType("com.sap.relation.besrv.relateaddperson.PersonRefVO");
resQueryFilter.setCollectionAttribute("personRef");
resQueryFilter.setAttribute("personRef_var.refObject.key");
else
strParamName = subAttrName;
dotIndex = strParamName.indexOf('.');
attrName = (dotIndex == -1) ? strParamName : strParamName.substring(0, dotIndex);
subAttrName = (dotIndex == -1) ? null : strParamName.substring(dotIndex + 1, strParamName.length());
resQueryFilter = new com.sap.caf.rt.bol.util.IntQueryFilter((com.sap.caf.rt.bol.util.QueryFilter) qf);
{ resQueryFilter.setCollectionType("com.sap.relation.besrv.relateaddperson.PersonRefVO");
resQueryFilter.setCollectionAttribute("personRef");
resQueryFilter.setAttribute("personRef_var.refObject." + strParamName);
</code>
Be carefull while changing template because this generated piece of coding is used in many places.

FindBy method in CMP

Hi
I would like to know if there is a way of get case insensitive results
from database using CMP findBy methods ?
Thanks
Lavanya

In CMP, we don't want to or can not send queries directly to the database. The EJB container manages the O.R. mapping. It is likely the relational structure of your beans is unknown.
We also can not assume the database he or she is using has the capacity to create materialized views.

Java.lang.NoSuchMethodError: java/util/Vector method revove...

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.

Is it possible to create findBy method for collection of ids?

subj -
I have a set of ids (HashSet of Integers).
is it possible to create such findBy method which retrieves group of entity beans with ids specified in the set?

You could do something like:
PrimKeyBean
public PrimKey ejbSelectPrimKey(Long key) throws FinderException;
public Collection getPrimKeys(Collection keyset) {
try{
    Vector output = new Vector();
    Iterator it = keyset.iterator();
    while(it.hasNext()){
      output.add(ejbSelectPrimKey((Long)it.Next()));
    return output;
} catch (FinderException fe) {}
...deploymentdescriptor.ejb
<query>
<query-method>
<method-name>ejbSelectPrimKey</method-name>
</query-method>
<ejb-ql>
SELECT OBJECT(o) FROM pkTable o WHERE pkTablePK = ?1
</ejb-ql>
</query>
...client
Collection c = primKey.getPrimKeys(keyset);
...

FindBy method naming rules

What are the rules for naming the findBy methods?
I want to find entity Bean by two fields. e.g. Want find entity Bean on orderNumber and customerId field.
I created method like findByOrderNumberAndCustomerId(String orderNumber, String customerId)
It let me generate code and deploy the bean, but at runtime it does not return any entity bean or Collection. It throws exception.
Thanks for your help.
A

There is no problem with your method name, I think if u could post the code, it will be better.
or try using EJB QL for searching as
public Animal findbyId(int Id){
return (Animal) em.createQuery("Select e From Animal e where e.id = :id").setParameter("id",Id).getSingleResult();
}

FindBy() Method finds the same bean more than once

I am desperate.
Can anyone at least tell me if they ever heard of a problem similar to this in a CMP Entity Bean?
PROBLEM: My findByMemberOrHash(MemberLocal, String) method returns a Collection with FOUR references to the same Entity Bean from a table that has only one Entity Bean persisted in it!
Yet, my findByMember(MemberLocal) and findByHash(String) both work perfectly and return a Collection with only one element -- the single Entity Bean in the table.
Here is the relevant code and table info:
My Entity Beans are named LoggedIn and are persited in a MySql table named loggedings that has but 3 columns:PK:         PrimaryKey (Integer).
HASH:       persistance field (String).
members-pk: relationship field (Foreign Key to Member Bean table (Integer)For this test the table persisted a single Bean. Here is the data base SELECT:mysql> SELECT * FROM loggedins;
+----+------+------------+
| PK | HASH | members_pk |
+----+------+------------+
| 40 | X    |          1 |
+----+------+------------+
1 row in set (0.00 sec)Here is my logger output from the server:
LoggerBean is a Session bean that is processing the login.
To test, I had it run three findBy()s ... Member Or Hash, Member Only, and Hash OnlyINFO [LoggerBean] Print out findByMemberOrHash()

Its too trivial a test to break it down any further.
Especially since the single parameter SELECTs work perfectly.

NoSuchMethodError: method trim(J)V not found when calling loadDataFromInputStream

     Hi, I4m trying to put data on a ORDImage field using java but, when I call the method loadDataFromInputStream I got the message:
Exception in thread "main" java.lang.NoSuchMethodError: oracle.sql.BLOB: method trim(J)V not found.
     Does anyone can help me ?
     Thanks in advance,
     Alexandre.

the browser in question is running the ms jvm which is quite old and the source of many security problems. It is also obviously lacking the specific constructor for four floats...
You solutions:
1) scrap support for this jvm. Let the user know they should upgrade
2) test for presence of crappy vm and provide workarounds as needed
3) do nothing

Java.lang.NoSuchMethodError:java/io/File:

hi all,
i have just a dbf file and no database server, can i still use the JDBC driver to make a connnection?
If yes, i put my dbf file in the Tomcat root directory and write con=DriverManager.getConnection("jdbc:DBF://localhost:8080/","","");
but it always returns an error
java.lang.NoSuchMethodError:java/io/File: method getCanonicalFile()Ljava/io/File ; not found
Anyone know what's wrong?
Below is the driver readme for the URL format:
URL format:
Direct Access:
jdbc:DBF:[/]/[DatabasePath]
For example: "jdbc:DBF:/." "jdbc:DBF:/../dbffiles"
Access by DBF Server: Skip it if you don't use RMI or JINI.
jdbc:DBF:[/][host][:port]/[DatabasePath]
Default host:localhost port:2129 DatabasePath:
For example: "jdbc:DBF://domain.com:3099/../dbffiles" if one DBFServer is run on the 3099 port of domain.com
*/

We got a similar error the other day trying to grab the Meta-Data.
Once I took those lines out everything else worked fine. Ie our connection and loading code was fine.
It seems that not all methods are supported on all implementations of the jdbc/odbc drivers.
Our current issue has to do with having a lot of different databases, and not wanting to set up ODBC links to all of them (or wanting to find an easy way to do that).

Problem with traverse method

Hi, I am having this problem:
I made a CustomItem, a TextField, now I overloaded the traverse method, so if the keycode is Canvas.UP or Canvas.DOWN then return false else return true.
The problem is that when I press the left or rigth button it also returns false and not true.
and there is another problem with traverse, before returning false or true I set a boolean and call to repaint to draw it on some way if its selected or not, the paint method is being called but it just dont draw as desired.
protected void paint(Graphics g, int ancho, int alto) {
          System.out.println ("Dentro del paint, seleccionado="+seleccionado);
          try {
               g.drawString(label, 0, 0, Graphics.TOP|Graphics.LEFT);
               if (!seleccionado) {
                    g.setColor(120, 120, 120);
               g.drawRect(0, 4, tama�oTexto+8, 25);
               if (seleccionado) {
                    g.setColor(255, 255, 255);
                    g.fillRect(1, 5, (tama�oTexto+8-1), 23);
               g.setColor(0, 0, 0);
               if (!seleccionado) {
                    g.setColor(80, 80, 80);
               g.drawString(texto, 4, 7, Graphics.TOP|Graphics.LEFT);
               if (seleccionado) {
                    int cursorX=Font.getDefaultFont().charsWidth((texto.substring(0, idLetraActual)).toCharArray(), 0, texto.substring(0, idLetraActual).length())+4;
                    g.drawChar('|', cursorX, 7, Graphics.TOP|Graphics.LEFT);
          } catch (Exception E){
               E.printStackTrace();
     }the traverse method set the seleccionado variable and calls to repaint but instead of being false the paint method is drawing it as true (most of times).

I have a problem with findByxxx() method.. in
Container managed bean.
i have
Collection collection =
home.findByOwnerName("fieldValue");
specified in my Client Program, where ownerName is the
cmp fieldname..
and
public Collection findByOwnerName(String ownerName)
throws RemoteException, FinderException
defined in my home interface.
i have not mentioned the findBy() method anywhere else
(Bean class). You have to describe the query in the deployment descriptor.
>
Even if i have a same "fieldValue" in the database
(Oracle), which i specified in findBy() method, iam a
result of owner Not found, which is not the case as i
have that owner name.
for the same application if i use findByPrimaryKey(),
it is working..
Can any one please post me the solution.

Find by methods

I am doing some programming with CMP where i have one findBy Method , which is returning a Collection, By the way i have couple of get/set methods defined in the Bean implementation class , i need to access the get methods of which , kindly let me know how to do i access those from the client code !!! Do i need to declare those methods in the Remote interface ?
Thanks
Mathew

EmployeeRemote
employee_remote=(EmployeeRemote)PortableRemoteObject.na
row(it.next(),EmployeeRemote.class);
System.out.println("Id"+ employee_remote.getId());---------------------------------------------------------
Wrong!!
Object ref = ctx.lookup("jndiName");
EmployeeHome employee_home = (EmployeeHome) PortableRemoteObject.narrow(ref, EmployeeHome.class);
EmployeeRemote employee_remote = employee_home.create(....);
String name = employee_remote.getName() <--- getXXX method
You first lookup the jndi name to obtain a reference to the ejb. Then you narrow it down to the HOME INTERFACE TYPE!!! You can invoke create[if you want to create a new row in the database] or call findByPrimaryKey [if you want a remote reference to an existing row].
Once you get the remote reference , you can invoke the getXXX/setXXX methods on it. Have a look at the J2EE tutorial for a step by step procedure.
http://java.sun.com/j2ee/tutorial/1_3-fcs/doc/J2eeTutorialTOC.html
Cheers
Kindly let me know if i am calling a right code --
Thanks
