Data to Java Objects
I was wondering how i could eliminate the sql code in my jdbc calls. I have not EJB environment and was wondering if OO to relational mapping would be a solution or a solution like dbgen ????
Who could shedsom light...
- Marco
you don't want to use EJB does not mean you can't steal idea from EJB :-)
basically, you could develop a simple tool to map each table in the database to a Java class as a Java bean with getters and setters. And you should have a pattern, say like EJB, that has interfaces for searching, add, delete etc. and seals all SQL in methods.
this is a rather rough idea. but you could get idea from EJB.

JAVA Object to XML to JAVA to XML
I have to achieve below in java:-
-Create input XMLs from Java class (that resides in a jar).
-Take input from user then store that data to Java object and submit for processing.
-After processing print response java object again in XML.
What is the best API to achieve this. Will be helpful if any example is available.Thanks for the Reply =)
I have a Java Object that have some fileds like arraylist<Class> I want to take care of these fields as well.
If that arrayList<Class> have another fields that can be normal fileds or arraylist of another class, need to take care of all fields during XML generation
Example:-
Root Class have below fields
private int ArCt;
private ArrayList<ClassChild1> Ar;
Setters
Getters
ClassChild1.class
private int PlnCd;
private int cArCt;
private ArrayList cAr<ClassChild2> cAr;
ClassChild2.class
private String PlNm
XML Needed - Example from above object
<root>
<ArCt>1</ArCt>
<Ar>
<ClassChild1>
<PlnCd>S</PlnCd>
<cArCt>2</<cArCt>
<cAr>
<ClassChild2>
<PlNm>Plan1</PlNm>
</ClassChild2>
<ClassChild2>
<PlNm>Plan2</PlNm>
</ClassChild2>
</cAr>
</ClassChild1>
</Ar>
</root>

If so, I don't think that ever really caught on. Most programmers store the raw data, then pull it out and populate a class. The problem with storing the object is that new versions of classes come out and your old version is stored in the database. If you just store the data, you don't have to worry about what version is in the database. You can populate the new version of the class with the same data.
Also, others can use sql to query your data and use it for their own use independent of what you intended it for. I think most people use the (browser) based utility that comes with the database to create the tables, normalize them, set up primary keys, set up foreign keys, etc rather then run an sql statement as you did above. -

Java.sql.Date vs java.util.Date vs. java.util.Calendar
All I want to do is create a java.sql.Date subclass which has the Date(String) constructor, some checks for values and a few other additional methods and that avoids deprecation warnings/errors.
I am trying to write a wrapper for the java.sql.Date class that would allow a user to create a Date object using the methods:
Date date1 = new Date(2003, 10, 7);ORDate date2 = new Date("2003-10-07");I am creating classes that mimic MySQL (and eventually other databases) column types in order to allow for data checking since MySQL does not force checks or throw errors as, say, Oracle can be set up to do. All the types EXCEPT the Date, Datetime, Timestamp and Time types for MySQL map nicely to and from java.sql.* objects through wrappers of one sort or another.
Unfortunately, java.sql.Date, java.sql.Timestamp, java.sql.Time are not so friendly and very confusing.
One of my problems is that new java.sql.Date(int,int,int); and new java.util.Date(int,int,int); are both deprecated, so if I use them, I get deprecation warnings (errors) on compile.
Example:
public class Date extends java.sql.Date implements RangedColumn {
public static final String RANGE = "FROM '1000-01-01' to '8099-12-31'";
public static final String TYPE = "DATE";
* Minimum date allowed by <strong>MySQL</strong>. NOTE: This is a MySQL
* limitation. Java allows dates from '0000-01-01' while MySQL only supports
* dates from '1000-01-01'.
public static final Date MIN_DATE = new Date(1000 + 1900,1,1);
* Maximum date allowed by <strong>Java</strong>. NOTE: This is a Java limitation, not a MySQL
* limitation. MySQL allows dates up to '9999-12-31' while Java only supports
* dates to '8099-12-31'.
public static final Date MAX_DATE = new Date(8099 + 1900,12,31);
protected int _precision = 0;
private java.sql.Date _date = null;
public Date(int year, int month, int date) {
// Deprecated, so I get deprecation warnings from the next line:
super(year,month,date);
if(! isWithinRange(this))
throw new ValueOutOfRangeException((RangedColumn)this, "" + this);
public Date(String s) {
super(0l);
// Start Cut-and-paste from java.sql.Date.valueOf(String s)
int year;
int month;
int day;
int firstDash;
int secondDash;
if (s == null) throw new java.lang.IllegalArgumentException();
firstDash = s.indexOf('-');
secondDash = s.indexOf('-', firstDash+1);
if ((firstDash > 0) & (secondDash > 0) & (secondDash < s.length()-1)) {
year = Integer.parseInt(s.substring(0, firstDash)) - 1900;
month = Integer.parseInt(s.substring(firstDash+1, secondDash)) - 1;
day = Integer.parseInt(s.substring(secondDash+1));
} else {
throw new java.lang.IllegalArgumentException();
// End Cut-and-paste from java.sql.Date.valueOf(String s)
// Next three lines are deprecated, causing warnings.
this.setYear(year);
this.setMonth(month);
this.setDate(day);
if(! isWithinRange(this))
throw new ValueOutOfRangeException((RangedColumn)this, "" + this);
public static boolean isWithinRange(Date date) {
if(date.before(MIN_DATE))
return false;
if(date.after(MAX_DATE))
return false;
return true;
public String getRange() { return RANGE; }
public int getPrecision() { return _precision; }
public String getType() { return TYPE; }
}This works well, but it's deprecated. I don't see how I can use a java.util.Calendar object in stead without either essentially re-writing java.sql.Date almost entirely or losing the ability to be able to use java.sql.PreparedStatement.get[set]Date(int pos, java.sql.Date date);
So at this point, I am at a loss.
The deprecation documentation for constructor new Date(int,int,int)says "instead use the constructor Date(long date)", which I can't do unless I do a bunch of expensive String -> [Calendar/Date] -> Milliseconds conversions, and then I can't use "super()", so I'm back to re-writing the class again.
I can't use setters like java.sql.Date.setYear(int) or java.util.setMonth(int) because they are deprecated too: "replaced by Calendar.set(Calendar.DAY_OF_MONTH, int date)". Well GREAT, I can't go from a Date object to a Calendar object, so how am I supposed to use the "Calendar.set(...)" method!?!? From where I'm sitting, this whole Date deprecation thing seems like a step backward not forward, especially in the java.sql.* realm.
To prove my point, the non-deprecated method java.sql.Date.valueOf(String) USES the DEPRECATED constructor java.util.Date(int,int,int).
So, how do I create a java.sql.Date subclass which has the Date(String) constructor that avoids deprecation warnings/errors?
That's all I really want.
HELP!I appreciate your help, but what I was hoping to accomplish was to have two constructors for my java.sql.Date subclass, one that took (int,int,int) and one that took ("yyyy-MM-dd"). From what I gather from your answers, you don't think it's possible. I would have to have a static instantiator method like:public static java.sql.Date createDate (int year, int month, int date) { ... } OR public static java.sql.Date createDate (String dateString) { ... }Is that correct?
If it is, I have to go back to the drawing board since it breaks my constructor paradigm for all of my 20 or so other MySQL column objects and, well, that's not acceptable, so I might just keep my deprecations for now.

Invoking a AXIS Web Service with a Java object as input argument
Hi
I've been trying to execute a bpel process that invokes a web service deployed through axis.
This web service takes a java object as input argument as opposed to data types that are directly mapped to java types through the SOAP engine.
I deployed and tested the service outside of BPEL using a test client class. Everything works well.
When I try to configure the "Assign" and "Invoke" activities so that service can be invoked, I cannot see the data structure through the variable picker and I see the following message:
"The element {urn:ComplexTypeWebService}TimeSheetBean is not know to the schema container. Perhaps a schema file that uses it needs to include or import its definition.There mat also be an XML schema issue (non resolvable schema) which prevents {urn:ComplexTypeWebService}TimeSheetBean from being seen by the schema processor."
Is there any example that demonstrates how to invoke an axis web service in such scenario? What am I doing wrong?
Please, let me know.The passing of Java objects in and out of a web service is NOT supported. variables must be xml documents defined by a XML schema. In my opinion, missing Java object and WSDL is not a good idea. -Edwin

Urgent: How to find out the size in bytes of java object
Hi Experts,
We've a requirement that we need to find out the size of a java object at run time, is there a direct java API to get the size of a composite object in memory?
Here is my requirement: We are adding string objects (which is an xml string of considerable size) into a List. After reaching certain size limit (lets say 5MB) of the list i need to put this data into DB as a CLOB. So every time I add a string object to the list, I need to see if the total size of the list exceeds the limit and if yes, flush the results into DB.
I am not sure if java has a direct API for this, if not what is the beast way to do it, it s critical requirement for us.
It would be really great if someone could help us out.
Thank you,
-Shibu.>

Could you explain your actual requirement a little more fully.
1. Is each individual string a separate XML string? Or is it just a fragment? Why would you just concatenate them together into a CLOB? That won't produce valid XML and it won't let you easily separate the pieces again later. So provide a simple example showing some strings and how you need to manipulate them.
2. Are you using these xml strings in Java at all? Or are you just loading them into the database?
For example if you are just loading them into the database you don't need to create a list. Just create a CLOB in Java and append each string to the CLOB. Before you append each one you can check to see if the new string will put you over your length limit. If it will then you write the CLOB to the database, empty the CLOB and start appending again to the new clob instance.
If you explain what you are really trying to do we might be able to suggest some better ways to do it. -

I work on a Win2000 platform and Office 97.
Someone knows the reason of this error and can suggest what to make.
Thanks in advance.
Antonio M.Antonio, maybe you can post this back to the Jacob list. As an alternative to Jacob, what about Apache POI or writing the data as comma-delimited and opening the file using Runtime?
Hope that may help.
Good luck. -
How to parse XML to Java object... please help really stuck
Thank you for reading this email...
If I have a **DTD** like:
<!ELEMENT person (name, age)>
<!ATTLIST person
id ID #REQUIRED

<!ELEMENT name ((family, given) | (given, family))>
<!ELEMENT age (#PCDATA)>
<!ELEMENT family (#PCDATA)>

the **XML** like:
<person id="a1">
<name>
<family> Yoshi </family>
<given> Samurai </given>
</name>
<age> 21 </age>
</person>
**** Could you help me to write a simple parser to parse my DTD and XML to Java object, and how can I use those objects... sorry if the problem is too basic, I am a beginner and very stuck... I am very confuse with SAXParserFactory, SAXParser, ParserAdapter and DOM has its own Factory and Parser, so confuse...
Thank you for your help, YoHi, Yo,
Thank you very much for your help. And I Wish you are there...I'm. And I plan to stay - It's sunny and warm here in Honolulu and the waves are up :)
A bit more question for dear people:
In the notes, it's mainly focus on JAXB,
1. Is that mean JAXB is most popular parser for
parsing XML into Java object? With me, definitely. There are essentially 3 technologies that allow you to parse XML documents:
1) "Callbacks" (e.g. SAX in JAXP): You write a class that overrides 3 methods that will be called i) whenever the parser encounters a start tag, ii) an end tag, or iii) PCDATA. Drawback: You have to figure out where the heck in the document hierarchy you are when such a callback happens, because the same method is called on EACH start tag and similarly for the end tag and the PCDATA. You have to create the objects and put them into your own data structure - it's very tedious, but you have complete control. (Well, more or less.)
2) "Tree" (e.g. DOM in JAXP, or it's better cousin JDOM): You call a parser that in one swoop creates an entire hierarchy that corresponds to the XML document. You don't get called on each tag as with SAX, you just get the root of the resulting tree. Drawback: All the nodes in the tree have the same type! You probably want to know which tags are in the document, don't you? Well, you'll have to traverse the tree and ask each node: What tag do you represent? And what are your attributes? (You get only strings in response even though your attributes often represent numbers.) Unless you want to display the tree - that's a nice application, you can do it as a tree model for JTree -, or otherwise don't care about the individual tags, DOM is not of much help, because you have to keep track where in the tree you are while you traverse it.
3) Enter JAXB (or Castor, or ...): You give it a grammar of the XML documents you want to parse, or "unmarshall" as the fashion dictates to call it. (Actually the name isn't that bad, because "parsing" focuses on the input text while "unmarshalling" focuses on the objects you get, even though I'd reason that it should be marshalling that converts into objects and unmarshalling that converts objects to something else, and not vice versa but that's just my opinion.) The JAXB compiler creates a bunch of source files each with one (or now more) class(es) (and now interfaces) that correspond to the elements/tags of your grammar. (Now "compiler" is a true jevel of a misnomer, try to explain to students that after they run the "compiler", they still need to compile the sources the "compiler" generated with the real Java compiler!). Ok, you've got these sources compiled. Now you call one single method, unmarshall() and as a result you get the root node of the hierarchy that corresponds to the XML document. Sounds like DOM, but it's much better - the objects in the resulting tree don't have all the same type, but their type depends on the tag they represent. E.g if there is the tag <ball-game> then there will be an object of type myPackage.BallGame in your data structure. It gets better, if there is <score> inside <ball-game> and you have an object ballGame (of type BallGame) that you can simply call ballGame.getScore() and you get an object of type myPackage.Score. In other words, the child tags become properties of the parent object. Even better, the attributes become properties, too, so as far as your program is concerned there is no difference whether the property value was originally a tag or an attribute. On top of that, you can tell in your schema that the property has an int value - or another primitive type (that's like that in 1.0, in the early release you'll have to do it in the additional xjs file). So this is a very natural way to explore the data structure of the XML document. Of course there are drawbacks, but they are minor: daunting complexity and, as a consequence, very steep learning curve, documentation that leaves much to reader's phantasy - read trial and error - (the user's guide is too simplicistic and the examples too primitive, e.g. they don't even tell you how to make a schema where a tag has only attributes) and reference manual that has ~200 pages full of technicalities and you have to look with magnifying glas for the really usefull stuff, huge number of generated classes, some of which you may not need at all (and in 1.0 the number has doubled because each class has an accompanying interface), etc., etc. But overall, all that pales compared to the drastically improved efficiency of the programmer's efforts, i.e. your time. The time you'll spend learning the intricacies is well spent, you'll learn it once and then it will shorten your programming time all the time you use it. It's like C and Java, Java is order of magnitude more complex, but you'd probably never be sorry you gave up C.
Of course the above essay leaves out lots and lots of detail, but I think that it touches the most important points.
A word about JAXB 1.0 vs. Early Release (EA) version. If you have time, definitively learn 1.0, they are quite different and the main advantage is that the schema combines all the info that you had to formulate in the DTD and in the xjs file when using the EA version. I suggested EA was because you had a DTD already, but in retrospect, you better start from scratch with 1.0. The concepts in 1.0 are here to stay and once your surmounted the learning curve, you'll be glad that you don't have to switch concepts.
When parser job is done,
what kind of Java Object we will get? (String,
InputStream or ...)See above, typically it's an object whose type is defined as a class (and interface in 1.0) within the sources that JABX generates. Or it can be a String or one of the primitive types - you tell the "compiler" in the schema (xjs file in EA) what you want!
2. If we want to use JAXB, we have to contain a
XJS-file? Something like:In EA, yes. In 1.0 no - it's all in the schema.
I am very new to XML, is there any simpler way to get
around them? It has already take me 4 days to find a
simple parser which give it XML and DTD, then return
to me Java objects ... I mean if that kind of parser
exists....It'll take you probably magnitude longer that that to get really familiar with JAXB, but believe me it's worth it. You'll save countless days if not weeks once you'll start developing serious software with it. How long did it take you to learn Java and it's main APIs? You'll either invest the time learning how to use the software others have written, or you invest it writing it yourself. I'll take the former any time. But it's only my opinion...

How to pass the java object into the spring controller
Hi Friends
When I hit the url at the first time my call goes to the spring controller and sets the userDetails objects in the modelAndView.addObject("userDetails", userDetails.getUserDetails()) and returns the userDetails.html page. if I click any link in the same page i want to pass same (userDetails) object thru javascript or jquery and calls the another(controller) method and returns the same (userDetails.html) page.
It means how can i pass the java object thru javascript or jquery and calls the controller. if i get the same object in my controller i can avoid calling the db again. please help me out to resolve this issue. i am tired of fixing this issue.
Regards
Sherin PoojaIf you want to avoid calling the database again then cache the data.
However before you do that make sure that calling the database, in the context of YOUR system, is going to be an actual problem.
For example there is absolutely no point in caching a User object when only one user an hour is actually using the system. -

return (au.com.xxx.jaxb.DateAdapter.printDate(value));
^
2 errors
compilation failed, errors should have been reportedWhich means that wsimport or xjc needs to know the classpath to find au.com.xxx.jaxb.DateAdapter.
But how do I pass the classpath from wsimport to the JAXB compiler ?
There is the -B option in wsimport, but I could not get it to work.
If I read it correctly, I should be able to pass the -classpath option to the JAXB compiler from wsimport via -B.
I tried:
salvojo@AUD20901BL /cygdrive/c/workspace/JSF/insurance
$ /cygdrive/c/java/jdk1.7.0_09/x64/bin/wsimport -keep -s gen-src -B"-classpath WebContent/WEB-INF/classes" -b external/wsdl/jaxb-bindings.xml -wsdllocation /wsdl/Member.wsdl -d WebContent/WEB-INF/classes external/wsdl/Member.wsdl
no such JAXB option: -classpath WebContent/WEB-INF/classes
Usage: wsimport [options] <WSDL_URI>
where [options] include:
-b <path> specify jaxws/jaxb binding files or additional schemas
(Each <path> must have its own -b)
-B<jaxbOption> Pass this option to JAXB schema compiler
-catalog <file> specify catalog file to resolve external entity references
supports TR9401, XCatalog, and OASIS XML Catalog format.
-d <directory> specify where to place generated output files
<...snipped...>... where WebContent/WEB-INF/classes is the classpath where au.com.xxx.jaxb.DateAdapter.class could be found. Obviously it did not like it.
Also, why is wsimport generate org.w3._2001.xmlschema.Adapter1.java ? All it is doing is wrapping up the exact same call that I have specified in my DateAdapter. How can I tell wsimport or xjc to NOT create that extra Adapter1.java and simply directly use my DateAdapter ??create additional column of type LONG to represent date.
dateFormat is of type java.util.Date:
long newLongDate = dateFormat.getTime();
select object(b) from MyEntity b where b.MYLONGDATE > ?1 and b.MYLOGDATE <= ?2 -
Using the Data Engine Java API
I try to use the Data Engine Java API to generate an XML document from database data.
So as mentioned in the documentation Business Intelligence Publisher User's Guide Release 10.1.3.2 (page 4-26 to 4-27)
a) I created a java class (using Jdev Version 11.1.1.0.0)
package oracle.apps.XMLPublisher.client;
import com.sun.java.util.collections.Hashtable;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;
import oracle.apps.xdo.XDOException;
import oracle.apps.xdo.dataengine.DataProcessor;
public class XMLFileGenerator {
public XMLFileGenerator() {
public static void dataEngine() throws ClassNotFoundException, Exception {
XMLFileGenerator xMLFileGenerator = new XMLFileGenerator();
try {
//Initialization instantiate the DataProcessor class//
DataProcessor dataProcessor;
dataProcessor = new DataProcessor();
//Set Data Template to be executed
dataProcessor.setDataTemplate("PERFRBS.xml");
Hashtable parameters;
parameters = new Hashtable();
parameters.put("P_LEGAL_ENTITY_ID", "3259");
parameters.put("P_TRU_ID", "3262");
parameters.put("P_YEAR", "2009");
dataProcessor.setParameters(parameters);
// Now set the jdbc connection to the database that you
// wish to execute the template against.
// This sample assumes you have already created
// the connection object 'jdbcConnection'
Class.forName("oracle.jdbc.OracleDriver");
String url =
"jdbc:oracle:thin:@ap6005sdb.us.oracle.com:1526:hremeadv";
Connection jdbcConnection;
jdbcConnection= DriverManager.getConnection(url, "apps", "*****");
dataProcessor.setConnection(jdbcConnection);
System.out.println("Here1");
// Specify the output directory and file for the data file
dataProcessor.setOutput("BilanSocial.xml");
System.out.println("Here2");
dataProcessor.processData();
System.out.println("Here3");
} catch (SQLException e) {
System.out.println("SQLException " + e.getMessage());
} catch (XDOException e) {
System.out.println("XDOException" + e.getMessage());
public static void main(String[] argv) throws ClassNotFoundException,
Exception {
XMLFileGenerator xmlPublisher = new XMLFileGenerator();
XMLFileGenerator.dataEngine();
b) to generate my xml file based on the following data template
<?xml version="1.0" encoding="ISO-8859-1" ?>
<dataTemplate name="PERFRBS" defaultPackage="" version="1.0">
<parameters>
<parameter name="P_LEGAL_ENTITY_ID" dataType = "number"></parameter>
<parameter name="P_TRU_ID" dataType = "number"></parameter>
<parameter name="P_YEAR" dataType = "number"></parameter>
</parameters>
<lexicals>
</lexicals>
<dataQuery>
<sqlStatement name="Q_INDICATORS">
<![CDATA[ SELECT pai.action_information3 YEAR,
pai.action_information17 INDICATOR_VALUE
FROM pay_action_information pai
WHERE pai.action_information_category = 'HR_FR_BS'
AND pai.action_context_type = 'PA'
AND pai.action_information1 = :P_LEGAL_ENTITY_ID
AND pai.action_information2 = :P_TRU_ID
AND pai.action_information3 = :P_YEAR
]]>
</sqlStatement>
</dataQuery>
<dataStructure>
<group name="G_YEARS" dataType="varchar2" source="Q_INDICATORS">
<element name="YEAR" dataType="varchar2" value="YEAR"/>
<element name="INDICATOR_VALUE" dataType="number" value="INDICATOR_VALUE"/>
</group>
</dataStructure>
</dataTemplate>
---> But when I run it , it fails when calling the data processor with the following error
D:\Jdeveloper11g\jdk\bin\javaw.exe -client -classpath "D:\Jdeveloper11g\jdevhome\XMLPublisher\src\Client\classes;D:\BI publisher\XMLP562_WIN\XMLP562_WIN\manual\lib\versioninfo.jar;D:\BI publisher\XMLP562_WIN\XMLP562_WIN\manual\lib\xdocore.jar;D:\BI publisher\XMLP562_WIN\XMLP562_WIN\manual\lib\collections.jar;D:\BI publisher\XMLP562_WIN\XMLP562_WIN\manual\lib\xmlparserv2-904.jar;D:\BI publisher\XMLP562_WIN\XMLP562_WIN\manual\lib\i18nAPI_v3.jar;D:\Jdeveloper11g\jdbc\lib\ojdbc14dms.jar;D:\Jdeveloper11g\jlib\orai18n.jar;D:\Jdeveloper11g\diagnostics\lib\ojdl.jar;D:\Jdeveloper11g\jlib\dms.jar" -Dhttp.proxyHost=emeacache.uk.oracle.com -Dhttp.proxyPort=80 -Dhttp.nonProxyHosts= -Dhttps.proxyHost=emeacache.uk.oracle.com -Dhttps.proxyPort=80 -Dhttps.nonProxyHosts= oracle.apps.XMLPublisher.client.XMLFileGenerator

Thanks by advance for your helpMake sure you have the Oracle JDBC library setup in project parties and it's setup to export. The api's are fine. Have you looked at the BIPublisherIDE I wrote. All this code is already written for you. There is a manual on the site as well

How to store java objects in the database
Hi,
I am trying to store HttpSession state across Application Servers. Basically I am trying to build a sort of application cluster server on my own. I thought the best way to do this was to periodically store the HttpSession object from an application server in a database.
I created a table in Oracle 8i with a blob column. I use a PreparedStatement.setObject() method to store the HttpSession object in the database. My problem is, I don't know how to get the object back from the database.
Since ResultSet.getBlob returns the Blob locator, I need to read the BinaryInputStream to get all my data back. This tells me that getBlob basically works only for things like files, and cannot be used for Java objects.
Is there any way around this? Your input would be much appreciated.
Regards,
Somaiah.Thanks for the quick reply vramakanth.
Do I have to use a type map if I do this? Also does such a type map exist for the HttpSession class?
Thanks,
Somaiah. -
A way to access SVG event data for an object?
Is there a way to access the SVG event data for an object through scripting?
post this in the correct forum - you will get a better response (btw the correct forum is KVM)
to answer your question - any extra functionality above the MIDP1.0 specification will be manufacturer specific (and as such hardware dependant)
I only know 2 of the APIs extensivly (the Nokia and Siemens) neither of these offer access to the phonebook or the message folder (it would be a security risk) I don't think they provide the cell id either.
and no, there is no way to access the cellular phones OS. (on any phone!) it would completely destroy the purpose for having java on the phone.
