Help! wscompile generates inconvertible type java code?

Hi,
I am trying to create client code from Google AdWords WSDLs. I have to specify -f:explicitcontext to generate source code for <wsdlsoap:header> tag.
The generated source code has inconvertible types and cannot be compiled.
The compile error:
adwords_adgroup/ver_0_1/AdGroupInterface_Stub.java:1058: inconvertible types
found : java.lang.Object
required: long
operations.value = (long)_headerObj;
This is the command I run:
wscompile -d build/classes -s build/src -gen -keep -f:explicitcontext config.xml
This is config.xml:
<?xml version='1.0' encoding='UTF-8'?>
<configuration xmlns='http://java.sun.com/xml/ns/jax-rpc/ri/config'>
<wsdl location='https://sandbox.google.com/api/adwords/v12/AdGroupService?wsdl' packageName='com.tfmx.ws.adwords_adgroup.ver_0_1'/>
</configuration>
What is the problem and how can it be solved?
Thank you!

use this code . you have to pass userlogin and lookup name
Public String GetEmail(String UserLogin,String lookupcode)
String email;
try{
tcLookupOperationIntf lookupIntf = Platform.getService(tcLookupOperationIntf.class);
HashMap<String, String> lookupValues = getLookupHashMap(lookupIntf, lookupCode);
String found = lookupValues.get(UserLogin);
if (found!=null) email= "EMAIL A";
else
email= "EMAIL B";
}catch(Exception e){}
return email;
private HashMap<String, String> getLookupHashMap(tcLookupOperationsIntf lookupOperationsIntf, String lookupCode)throws tcAPIException,tcInvalidLookupException,tcColumnNotFoundException {
HashMap<String, String> lookupMap = new HashMap<String, String>();
          tcResultSet resultLookupHashMap = lookupOperationsIntf
                    .getLookupValues(lookupCode);
          int countResultLookupHashMap = resultLookupHashMap.getRowCount();
if (countResultLookupHashMap > 0) {
               for (int i = 0; i < countResultLookupHashMap; i++) {
                    resultLookupHashMap.goToRow(i);
                    lookupMap.put(resultLookupHashMap..getStringValue("Lookup Definition.Lookup Code Information.Code Key"),
resultLookupHashMap.getStringValue("Lookup Definition.Lookup Code Information.Decode"));

Need help in writing a small java code

Hi,
I have a small requirement where I need write a small java code. I am thinking of using array. Please suggest if you know the solution:
1. Need to compare user logon id is preset in the lookup table or not.
2. If user id present in the lookup then send type "A" mail
3. If user id in not present in the lookup then send type "B" email.
Please suggest.
Thanks,

Can anybody help on sending mail through Java Code

os.writeBytes("HELLO\r\n");
// You will add the email address that the server
// you are using know you as.
os.writeBytes("MAIL From: <[email protected]>\r\n");
// Who the email is going to.
os.writeBytes("RCPT To: <[email protected]>\r\n");
//IF you want to send a CC then you will have to add this

os.writeBytes("QUIT\r\n");
// Now send the email off and check the server reply.
// Was an OK is reached you are complete.

while((responseline = is.readLine())!=null)
{ System.out.println(responseline);
if(responseline.indexOf("Ok") != -1)
break;
} catch (IOException e) {
e.printStackTrace();
It is compiling and runnung properly. Please Help me on this.
Thanks.
Satya.

You're mishandling the responses. You terminate if you don't get an "Ok" string, but that's not how success is defined - you should get a 200 code back, typically with an "OK" (not caps) message.
It doesn't help that you're ignoring all of the server output after each command, so you never find out if anything goes wrong.
You're also reinventing a wheel. The JavaMail API exists for this: http://java.sun.com/products/javamail/

Generate IDL from Java Code, Classes, UML, etc?

Hi,
is is possible to generate IDL code from Java Code, Classes, UML, ... using JDeveloper?
I know this is somewhat reverse engeneering, but it would speed up the migration of our existing Java project...

Hi,
is is possible to generate IDL code from Java Code, Classes, UML, ... using JDeveloper?
I know this is somewhat reverse engeneering, but it would speed up the migration of our existing Java project...Unfortunately it does not. The IDL to Java conversion is handled under the covers by the idl2java.exe included with the database. You might want to search on google for a IDL generator from java source.
java2iiop (another tool) just generates IIOP stubs from classes and interfaces, but I don't think it creates IDL.

HELP NEED FOR INVOKING THE JAVA CODE INSIDE JSP

Hello,
any one knows how to Write a java code inside the .jsp files... please if any one knows it please ....help me .....

Need help for generating textboxes in java script

hii,
yes,we are discussing about text boxes that are dynamically generated.the cursor should go from one textbox to another by pressing enter key.(suppose we are having three rows and three columns,
and each column textboxes are having the same name,then the cursor should move from one textbox of first column first row to second row first column textbox ..& like that.That means the cursor should move downwards.
if any one knows the code,please help me.

hiii,
To move cursor from one textbox to another text box ,I have take the length of the textboxes of the first column.I used onkeyDown event .
in the function ,firest i checked the condition like
for(i=0;i<form1.box.length;i++) //box is the name of the textboxes
if(event.keyCode==13)
form1.box[i+1].focus();
return false;
by using this the cursor is moving from first text box to secon textbox and stops.
if i use event.returnValue=false; instead of return false ,then the cursor automatically going to the laxt textbox of the column.
my problem is how i can focus the cursor from one textbox to another textbox one after the other till the end.
if any one has solution please help me.
thanx.

It has nothing to do with classes. It is that you are reading to much info into memory at one time. If you are only going to cycle through the input line for line, anyway, then why don't you simply read the file (or whatever) a line at a time and process it as you read it, rather than loading the entire thing at once?

Help needed in understanding the Java code.

Hi All,
I have recently started learning the Java language. I came across this example and had a problem in understanding the output of the program. I could follow that if the continue statement is present in the below program the output is "Found 9 p's in the string" . But if the continue statement is removed I could not understand why the output would be "Found 35 p's in the string" .Is it because of the spaces and characters other than p... (eter ier icked a eck of ickled eers)
Example-----------------------
The continue statement skips the current iteration of a for, while , or do-while loop. The unlabeled form skips to the end of the innermost loop's body and evaluates the boolean expression that controls the loop. The following program, ContinueDemo , steps through a String, counting the occurences of the letter "p". If the current character is not a p, the continue statement skips the rest of the loop and proceeds to the next character. If it is a "p", the program increments the letter count.
class ContinueDemo {
public static void main(String[] args) {
String searchMe
= "peter piper picked a " +
"peck of pickled peppers";
int max = searchMe.length();
int numPs = 0;
for (int i = 0; i < max; i++) {
// interested only in p's
if (searchMe.charAt(i) != 'p')
continue;
// process p's
numPs++;
System.out.println("Found " +
numPs + " p's in the string.");
Here is the output of this program:
Found 9 p's in the string.
To see this effect more clearly, try removing the continue statement and recompiling. When you run the program again, the count will be wrong, saying that it found 35 p's instead of 9.

The answer is already in your example - "The unlabeled form skips to the end of the innermost loop's body and evaluates the boolean expression that controls the loop."
It unloads the current loop iteration when condition is matching. Loop is again starting from boolean expression inside loop declaration.

Sorry, I still don't get it. I don't know what you mean by a non-static way of using jars. The main method for launching an application is static so if you call that method, you will be using a static method. I don't know what you mean by a "jar method" either. Methods are inside classes. So far, all I can guess is you want to invoke a method in a class that happens to be inside a jar. Since people do this all the time without reflection, I don't see the problem.

Generate SVG with java

Hi all!
I want to generate and manipulate a SVG-file with Java, accoding to analyzed data from another java program. Should i see a SVG-file as a normal xml-file und do the task with normal DOM, or with Batik Toolkit from Apache? I tried to use Batik, but his Java Doc ist to bad, there are no informations about the classes and his fields and methods, so that i can't understand them. For example, what does this class "SVGPathSegArcRel" mean and how can i use it?
So i think, it is probably to use the normal DOM-Schnittstelle to generate an d manipulate the SVG, as SVG is XML-file. Is that correct? Or could someone give me any tipps?
Thanks in advance!
Di

You can certainly use the generic XML software (DOM and so on) to generate and manipulate SVG, because as you say, it is XML. But the other part of the problem is the "semantics" -- what should you do when you manipulate SVG? That is similar to saying that you can use any text editor to generate and manipulate Java code -- you can, but to produce anything useful you have to understand Java.
Similarly, you have to understand SVG. Maybe the Batik toolkit is supposed to help with that; I don't know anything about it myself. Your alternative is to learn about the SVG elements and attributes, everything in the SVG namespace, and produce SVG from your own code.

Okay, first suggestion is to never create database connections in JSP/Servlet. SInce you mentioned MVC, JSP is the View, and a servlet can be the controller to process requests and redirect accordingly.
This piece of code should be in a class invoked from the model layer (business logic components) preferably with some abstraction. Maybe you should search around for DAO pattern. That might give you an idea.

Clob/blob in java-code stored in database

Hi!
I want to write some java-code (CREATE OR REPLACE AND RESOLVE JAVA SOURCE NAMED...)
where I want to return an image as blob.
For doing that I have to initialize the blob in the java-code -correct?
I see many examples like
oracle.sql.BLOB.createTemporary(conn, false,oracle.sql.BLOB.DURATION_CALL)
In PL/SQL there is some similar:
dbms_lob.createtemporary(lob_loc => xmlclob, cache => TRUE, dur => dbms_lob.SESSION);
If I have to initialize the blob in the java source, how to do that (using empty_blob, but why using oracle...createTemporary then?)?
I don't want an connection to an remote database, the java-code will be in the database, so can I call createTemporary without >conn<?
(Oracle 10gR2, Windows, Linux, AIX)
The picture will be generated calling other java-code loaded with loadjava.
The java-source I want to write will be wrapped with PL/SQL.
Greetings
Bjørn

Hi!
It seems you can do this:
          try {
               conn = new OracleDriver().defaultConnection();                graphblob = oracle.sql.BLOB.createTemporary(conn, false,oracle.sql.BLOB.DURATION_CALL); // must init
               System.out.println("Blob is init");
          } catch ( java.sql.SQLException sEx ) {
               throw new RuntimeException ("No connection", sEx);

Where to Place Custom Java Code

We are planning on adding customized Java code to Identity Manager 8; XPRESS will be used to call the customized Java code.
Questions:
1) Where does this customised code reside in the Java Application Server (Glassfish)?
2) Does the customized Java code have to be packaged in a JAR file?
Many thanks for your help.

You would deploy custom Java code along with the IDM war/ear file. Classes go in the WEB-INF/classes/ folder, JARs in WEB-INF/lib/ and that is application server independant.
Class files or JARs? Do you have any build process for your IDM, like the custom build environment CBE, then the source files might end up as class files; if you are using a seperate build environment for those custom classes, then packaging them in a JAR would be the way to go.
Generally speaking, using a JAR for your custom code is neater; whether a class in classes/com/foo/bar/Foo.class or in lib/myfoobars.jar takes precedence over the other is up to the class loader and depending on your application server and its settings, the behavior might vary - so be careful about mixing use of those locations.
