SAXParser.parse never returns!
I'm using sockets to transfer xml data. When I feed my InputSource (containing the xml document) into the SAXPaser.parse method I can see the events being fired correctly (ie: startDocument, characters, startElement,etc) apart from the endDocument event. The parse method is executing all my code but it never returns! What should cause it to return? Do I need to close the socket connection or should it recognise when it has reached the final closing element?
I couldn't find that exact implementation but I looked into the crimson version and it reads until it hits an EOF. It's a reasonable guess that the xerces version does the same. I think it has to read in the whole file becasue it cannot tell whether the document is well-formed otherwise.

Regards,
TapasNo really, it will report all the error if you turn on the validation and implement the error hander methods(error()).
ALSO,
My XSD had "<xs:sequence>" which was causing the problem.
We had to change it to "<xs:all>". Now all the errors are getting reported.
thx! -

This is totally insane!! They took someone's money in a sec by 'MISTAKE' but haven't returned after 10days.
I already have chatted with two staffs about this but different from what they promised, this still has not solved yet!
My devoted time for this was totally wasted and I am still in suffering.
I think this is theft!!! What shall I do more?!I am really sorry to bring this issue to the forum but had no choice. Like I mentioned above, I already have contacted them but never returned me back. Sick of chatting with those staffs who act like answering machine and wasting my time because of their mistake. After I finally decided to post this last night, then they called me this morning that I have to wait 5days more.
Sorry again, and thanks for your reply.

JNI_CreateJavaVM() (1.4.0) NEVER returns if I call it from DLL !
Hello,
I'm invoking java application from C++ exe (Win2000) and this works almost fine (except DestroyJavaVM()), but if the same piece of code that handles Java resides in DLL then JNI_CreateJavaVM() (1.4.0) NEVER returns and the process gets stuck !!!
What could be the reason ?
Thanx !Hi,
JVM can start java application from DLL if the application (that embeds java application and DLL) has message loop (or simple endless while loop, I tested).

Toolkit.getDefaultToolkit() in Java service never returns on Windows
I'm stumped by this problem. It appears to be specific to a single machine as I can reproduce it reliably there but not on other machines. I'm hoping someone has some thoughts on what could be going on.
Here's the scenario:
I have Tomcat 5 running as a service on a new installed Windows 2000 Server with up to date service packs and j2sdk1.4.2_06. The service is configure to run headless.
I have a webapp that performs simple image transformations using AWT and Java2D. Any invocation of Toolkit.getDefaultToolkit() never returns. The thread just sits there consuming no CPU and does not throw an exception. I've narrowed it further to a call to new sun.awt.windows.WToolkit() in getToolKit(). sun.awt.windows.WToolkit is the value of the system property awt.toolkit.
I can reproduce this exact behavior in a different scenario: the server is running sshd on cygwin. If I ssh to the server and run the following class, it also hangs at new sun.awt.windows.WToolkit().
public class ToolkitTester
public static void main(String[] args)
System.out.println("awt.toolkit = " + System.getProperty("awt.toolkit"));
System.out.print("Invoking: new sun.awt.windows.WToolkit()... ");
new sun.awt.windows.WToolkit();
System.out.println("done.");
}Running this same class from a shell on the server works just fine.
I have tried j2sdk1.4.2_03 and jdk1.5 with the same results. I've replicated this second scenario (logging in over ssh) on another Windows 2000 server and do not see this behavior.
Any thoughts?
AlonOkay. Here's the fix...
The 'no video card' comment was actually pretty close. The issue appears to be with DirectDraw support. We found this by watching regmon as the testing code ran. Installing a new video driver may have addressed this but so does disabling using DirectDraw as described here:
http://java.sun.com/products/java-media/2D/forDevelopers/java2dfaq.html#dither

Wow. Weird one.

Problems with using SAXParser.parse with an InputStream
Hello:
I have successfully run the echo01 program from the XML tutorial. I made the following changes to parse the output from a servlet which generates an XML document.
URL recordedSensor = new URL("http://redbd01:8010/servlet/RecordedSensor?vin=1M000000000000001");
URLConnection rsConn = recordedSensor.openConnection();
// Parse the input
SAXParser saxParser = factory.newSAXParser();
saxParser.parse( rsConn.getInputStream(), handler);
I get the following errors when I try to run the code.
org.xml.sax.SAXParseException: java.lang.NullPointerException
at org.apache.crimson.parser.Parser2.parseInternal(Parser2.java:524)

at ServletInterface.main(ServletInterface.java:29)
I think I have the problem narrowed down to the handlers accessing the class variable out which is a Writer the emit() method uses to output the document. When I replace out.write in emit() with System.out.println() the code works.
I've tried accessing other class variables in the handler methods with similar results.
Anybody encountered similar problems? And what is the solution.
Thanks in advance,
GaryI have the same problem, if you find a solution let me know. I've double checked my objects to make sure their not null, I've checked my constructors in the extended default handler, not really sure where else to look, its such a simple program....

Select count(Key_Field) from table_name never returns
I am doing some scalability tests and am building a db w/table that will contain 400Million records. I am trying to see how far along I am in the process, and am experiencing this problem.
The select count(ID) never returns.
Does anyone have any suggestions for me as to how i might make it perform better? I am not too familiar with such large scale implementations, so any advice would be appreciated, and you can feel free to tell me the most basic info... (I do read docs, etc, but there might be a place I have not yet searched..)
The hardware is not an issue, at least for my testing, as it is as follows, and I see the IO on the arrays is busy, but not too busy, and that is to be expected, and we are neither CPU or RAM bound.
SUN E4800
12 CPUs
48GB RAM
2 T3 Arrays (fiber cards on different IO boards)
4 internal drives (2 on each IO board), not mirrored or RAIDedThis is always a troublesome type of query.
Are you trying to count the number of all rows in a table? You can try to ANALYZE the table, then from user_tables select the NUM_ROWS

SaxParser.parse(sok.getInputStream(), new handler()) [clarification please]
this code works, however i am not sure how/why?
i am interested in how Strings/characters are sent over tcp
streams:
here is sender:
Socket sok = new Socket(server, port);
OutputStreamWriter streamWriter = new OutputStreamWriter(sok.getOutputStream());
streamWriter.write(xmlString, 0, xmlString.length());i am ok with this.
i see that the OutputStreamWriter does "something" about converting the
socket's OutputStream to characters.
here is receiver:
SAXParser parser = saxFactory.newSAXParser();
Socket sok = serverSok.accept();
parser.parse(sok.getInputStream(), new MyHandler());see, i am plugging:
sok.getInputStream()
directly into the sax parser without providing context
that those bytes are characters (and what character encodings ).
so, what is going on? i might imagine using:
ObjectOutputStream.appendClass();
ObjectInputStream.resolveClass();to provide context that the byte stream are
characters of the "x" character set.
however, i am not using any
ObjectStreams.
if this is a ridiculous question, and the answer is
in the api somehow, i am sorry. i am not good
at always understanding the api.then my fundamental confusion is the difference between
java.io.Reader;
java.io.InputStream;
consider the set of polymorphic method signatures for the
SAXParser parse () methods.
parser.parse(sok.getInputStream(), new MyHandler());clearly invokes:
public void parse(InputStream is, DefaultHandler dh);however i don't see any method signature that matches:
parser.parse(new InputStreamReader(sok.getInputStream(), myCharSet), new MyHandler());for example, in the api, there is no:
public void parse(Reader r, DefaultHandler dh);this has been very helpful.
i will Google the interchangability of Reader/InputStream tomorrow, however any
further guidance would be welcomed. the java.io heirarchy confuses me. -
SAXParser.parse(resder, ...) ???
Hi;
Is there any way to pass SAXParser.parse() a Reader instead of an InputStream? I thought we were not supposed to use InputStreams anymore.
thanks - daveIs there any way to pass SAXParser.parse() a Reader instead of an InputStream? The SAX parser should implement a mechanisim to check the character encoding declared in the the XML prefix is compatible with the streamed octet data. If you use Reader for untrusted sources (ie pretty well anything other than StringReader, where the character encoding is well defined), you circumvent that error check.
I thought we were not supposed to use InputStreams anymore.Part of the role of an XML parser in dealing with the character encoding, so it is appropriate to use the stream that provide octets which encode characters rather than a reader that provides characters.

MobileService.SyncContext.PushAsync never returns in Release build
I am currently trying to create a windows phone app with azure mobile services but somehow offline sync is not working. When I create a release build and call await SyncContext.PushAsync() it never returns back to the context.
I dont really know what is happening,
Code:
await App.MobileService.SyncContext.PushAsync();
return true;
When I run a debug build everything works fine.
I can't understand, whats happening in Release mode?
Its a very urgent. Please provide a quick solution or setup a call with me.
Thanks,
Hema
hemaThank you for the answer, I added HttpMessageHandler to check which operation was causing the problem and a IMobileServiceSyncHandler, as I mentioned earlier when there is nothing to Push the syncing work fine and the pull can be made, but when the push
needs to send data the request passes by OnPushCompleteAsync and does not get to the LoggingHandler.SendAsync or to the ExecuteTableOperationAsync and on the Output console I can see the following exceptions are thrown but the PushAsync does not fail and never
ends.
A first chance exception of type 'System.Resources.MissingManifestResourceException' occurred in mscorlib.ni.dll

About the UI, this operation is triggered by the user (button) and is handle in an ICommand in a way that can only be triggered once and locked from other processes with a SemaphoreSlim, I add a little part of the sync code.
await this.MobileServiceClient.SyncContext.PushAsync(cancellationToken);
var query = SyncItemTable.CreateQuery().Where(syncItem => syncItem.UserId == userId);
await SyncItemTable.PullAsync("PullSyncItem", query, true, cancellationToken);
I am using the nugets WindowsAzure.MobileServices, 1.3.1 and WindowsAzure.MobileServices.SQLiteStore, 1.0.1
I appreciate a quick response this is a stopper bug for the next release of our application. -

I hope someone can shed some light on this...
- Rob (jack) LapenseeIt looks like you are modifying the object you are iterating over while you are iterating... not good. Say your gp only had one element, a LINE_TO. It will run through and call another LINE_TO in the switch, thus when it comes back to the while, there is a newly added point to interpret, so the iterator will never finish. Usually, most components throw a ConcurrentModificationException when this happens for this type of case. I'm not sure why the PathIterator doesn't.
In short, use a different reference in the loop then the one you are iterating over.

Recursive WITH (Recursive Subquery Factoring) Never Returns
11.2.0.2 database on Windows, SQL Developer Version 3.2.20.09, build MAIN-09.87 (Database and SQL Developer are on the same machine. I have also tried connecting to a Linux 11.2 database and have the same results.)
I've been doing some simple testing with recursive WITH (Recursive Subquery Factoring) and when I run this following statement in SQL*Plus it returns instantly. However when running in SQL Developer it never returns, I've let it run for quite a long time (172 seconds) and gotten nothing, I finally kill the statement. Once I ran it and even killing the job didn't come back. I can get an explain plan but if I try to run it, run as script or autotrace it never returns. I have only one plan in the plan_table for this test, and it's only 4 lines long. No errors, no messages.
WITH get_plan (query_plan, id, planlevel) as
select ' '||operation||' '||options||' '||object_name query_plan, id, 1 planlevel
from plan_table
where id = 0
union all
select lpad(' ',2*planlevel)||p.operation||' '||p.options||' '||p.object_name query_plan, p.id, planlevel+1
from get_plan g, plan_table p
where g.id = p.parent_id
SELECT QUERY_PLAN FROM GET_PLAN ORDER BY PLANLEVEL;Hi Jeff, using either give the same results. The query is "running", as is the little graphic with the bouncing gray bar is moving back and forth saying either "Query Results" or "Scriptrunner Task" as appropriate.
OK this is odd. I run a count(*) on plan_table in SQL*Plus and get 4, in SQL Developer I get 487. Hun? That makes no sense I'm connect as the same user in each. Where are all these other entries coming from and why can't I see them in SQL Plus? Does SQL Developer have it's own PLAN_TABLE?
**EDIT --- Yes that seems to be the case. The PLAN_ID I see in SQL Plus doesn't even exist in the SQL Deveropler version of the table. OK that's good to know. I assume the plan_table for SQL Developer is local to it somehow? It's not in the database as best I can see.
