How to catch Exception inside the native code
Hello,
I have an error of unexpected exception during running native code,it occurrs randomly, not every time.
the error text is:
An unexpected exception has been detected in native code outside the VM.
Unexpected Signal : 11 occurred at PC=0x9535F359
Function=acy_match+0xC6
Library=/usr/lib/libNegativeMatcher.so
I don't know what exactly cause the crash inside the c code but I think it might be memory leak . What I'm concern is that this exception cause program termination.
I have few questions:
1. This exception cause the java program to end. How can I catch this exception and avoid program termination?
2. What is 0xC6 in:
Function=acy_match+0xC6
and PC=0x9535F359?
Can it help me track the problem inside the native code?
Thanks for your help.

I have few questions:
1. This exception cause the java program to end. How
can I catch this exception and avoid program
termination?I suspect that would be a really bad idea. That particular signal very likely indicates that you have corrupted memory. Continuing is unlikely to work.
2. What is 0xC6 in:
As a guess it is an offset into the compiled code which indicates where the memory problem was detected.
That it unlikely to help you with a pointer/memory problem because that is where it was detected and not where it happened. By comparing the source you might be able to determine what was bad and then trace it back.

[JNI Beginner] GC of Java arrays returned by the native code
Hello all,
I am beginning with JNI, to integrate a C library that pilots an industrial equipment, into a java UI. This library enables to exchange various proprietary PDUs (protocol data units), with the equipment, up and down (request/replies). Both requests and replies are arrays of bytes (+char*+).
"Request" byte arrays are constructed by Java code, which passes them to the JNI code that glues with the lib. "Reply" byte arrays are returned to the Java code, which analyzes them.
The "return reply" part is very similar to this [tutorial example|http://java.sun.com/developer/onlineTraining/Programming/JDCBook/jniexamp.html] , which returns bytes read from a file. However there's something I don't understand with regard to garbage collection of the returned byte array:
- in this stock example, the C code creates a Java byte array fills it, and simply returns it (example code stripped to highlight only the parts relevant to my question):
jByteArray=(*env)->NewByteArray(env, size);
(*env)->SetByteArrayRegion(env, jByteArray, 0, size, (jbyte *)sourceBytes);
return (jByteArray);What will happen to this Java array (jByteArray) with regard to garbage collection?
- if it's no more referenced (the example Java code just systemouts it and forgets it), will it be eligible to GC?
- if it is referenced by a Java variable (in my case, I plan to keep a reference to several replies as the business logic requires to analyze several of them together), do regular Java language GC rules apply, and prevent eligibility of the array to GC as long as it's referenced?
That may sound obvious, but what mixes me up is that the same tutorial describes memory issues in subsequent chapters: spécifically, the section on "passing arrays states that:
[in the example] the array is returned to the calling Java language method, which in turn, garbage collects the reference to the array when it is no longer usedThis seems to answer "yes" to both my questions above :o) But it goes on:
The array can be explicitly freed with the following call:
{code} (*env)-> ReleaseByteArrayElements(env, jByteArray, (jbyte *)sourceBytes, 0);{code}Under what circumstances would one need to explicitly free jByteArray when it's about to be returned to the Java calling method? Or does this sentence apply to completely different situations (such as, when the array is +not+ returned as is to a Java method)?
The tutorial's next section has a much-expected +memory issues+ paragraph, from which I quote:
By default, JNI uses local references when creating objects inside a native method. This means when the method returns, the references are eligible to be garbage collected.I assume this means, +unless the references are assigned, in the Java code, to a Java variable+, right?
If you want an object to persist across native method calls, use a global reference instead. A global reference is created from a local reference by calling NewGlobalReference on the the local reference.I assume this enables the C code to maintain a global reference to a java object even if it's not referenced anymore from the Java variables, right?
I also checked the [JNI specification|http://download-llnw.oracle.com/javase/6/docs/technotes/guides/jni/spec/design.html#wp1242] , but this didn't clear the doubt completely:
*Global and Local References*
The JNI divides object references used by the native code into two categories: local and global references. Local references are valid for the duration of a native method call, and are automatically freed after the native method returns. Global references remain valid until they are explicitly freed.
Objects are passed to native methods as local references. All Java objects returned by JNI functions are local references. The JNI allows the programmer to create global references from local references. JNI functions that expect Java objects accept both global and local references. A native method may return a local or global reference to the VM as its resultAgain I assume the intent is that Global references are meant for objects that have to survive across native calls, regardless of whether they are referenced by Java code. But what worries me is that combining both sentences end up in +All Java objects returned by JNI functions are local references (...) and are automatically freed after the native method returns.+.
Could you clarify how to make sure that my Java byte arrays, be they allocated in C code, behave consistently with a Java array allocated in Java code (I'm familiar already with GC of "regular" Java objects)?
Thanks in advance, and best regards,

The fact that you created it in jni doesn't change that.
The array can be explicitly freed with the following call:
(*env)-> ReleaseByteArrayElements(env, jByteArray, (jbyte *)sourceBytes, 0);Under what circumstances would one need to explicitly free jByteArray when it's about to be returned to the Java calling method? Or does this sentence apply to completely different situations (such as, when the array is not returned as is to a Java method)?
Per what the tutorial says it is either poorly worded or just wrong.
An array which has been properly initialized it a just a java object. Thus it can be freed like any other object.
Per your original question that does not concern you because you return it.
In terms of why you need to explicitly free local references.

The created objects are tracked by the VM. When they are eligible to be collected they are.
If you create a local reference and do NOTHING that creates an active reference elsewhere then when the executing thread returns to the VM then the local references are eligible to be collected.
>
If you want an object to persist across native method calls, use a global reference instead. A global reference is created from a local reference by calling NewGlobalReference on the the local reference.That is not precise. The scope is the executing thread. You can pass a local reference to another method without problem.
I assume this enables the C code to maintain a global reference to a java object even if it's not referenced anymore from the Java variables, right?
It enables access to it to be insured across multiple threads in terms of execution scope. Normally you should not use them. -
How do I do use the custom code and format for a percentage with 2 decimals in Report Builder 3.0?
In Report Builder 3.0, I have the following custom code entered:
Public Function SafeDivide(Numerator as String, Denominator as String) as String
Try
If Numerator = “” or Denominator = “” then
Return “-“
End if
If Numerator = “-“ or Denominator = “-“ then
Return “-“
End If
If CDbl(Numerator) =0 or CDbl(Denominator) = 0 then
Return “-“
End if
If IsNothing(Numerator) or IsNothing(Denominator) then
Return "-"
End if
Return Val( ( (CDbl(Numerator) / CDbl(Denominator) )*100 ) )
Catch
Return "-"
End Try
End Function
I call the custom code in the cell with the following equation:
=Code.SafeDivide(sum(Fields!TY_UNITS.Value)-sum(Fields!LY_UNITS.Value),sum(Fields!LY_UNITS.Value))
I have the format for the cell set to 0.00%, but it’s not being followed.
I want the result to be formatted as a Percentage, but instead I get values like:
-78.9473684210
80
300
-100
I have the format for the cell set to 0.00%, but it’s not being followed.
How do I do use the custom code and format for a percentage with 2 decimals?Hi AngP,
After testing the issue in my local environment, I can reproduce it. Based on my research, I find this issue is caused by the type of Units_VAR_Percentage cell is string, while the type of CDbl(Parameters!Var_Threshold.Value) is double, so they cannot be
compared.
To fix this issue, we can add a hidden column (Textbox91) next to the Units_VAR_Percentage column, and type =(sum(Fields!TY_UNITS.Value)-sum(Fields!LY_UNITS.Value)) /sum(Fields!LY_UNITS.Value) as the expression. Then use the expression below to control the
BackgroundColor:
=iif(iif(reportitems!Units_VAR_Percentage.Value=CStr(format(reportitems!Textbox91.Value,"0.00%")),reportitems!Textbox91.Value,0)>CDbl(Parameters!Var_Threshold.Value),"Yellow","PaleTurquoise")
If there are any other questions, please feel free to ask.
Thanks,

SDK: Uncaught exception thrown in native code
We are using java and the DQM SDK, our XML validates and while we are trying to create a MultiRecordTransform, we get the following exception with no information to help diagnose the issue.
com.sap.emdq.EmdqException: Uncaught exception thrown in native code
We are using the dquractransformu shared object and have NCOALink enabled. We have successfully used the URAC transform without NCOALink. We receive no other errors or logs when starting up, and if we turn off NCOALink, it gets past creating the MR transform.
Is there any other information we can get to help us determine what the issue is?FYI: We found our setting in the XML that enabled NCOA processing to begin ( <PROVIDER_TYPE> ), but it would be much easier if the error indicated what was missing, instead of the generic "Uncaught exception thrown in native code". Maybe there is a config setting to get more informative exception messages?

chandra sekharI guess you are asking how to check it, then here is the answer
SQL Trace transaction ST05
The trace list has many lines that are not related to the SELECT statement in the ABAP program. This is because the execution of any ABAP program requires additional administrative SQL calls. To restrict the list output, use the filter introducing the trace list.
The trace list contains different SQL statements simultaneously related to the one SELECT statement in the ABAP program. This is because the R/3 Database Interface - a sophisticated component of the R/3 Application Server - maps every Open SQL statement to one or a series of physical database calls and brings it to execution. This mapping, crucial to R/3s performance, depends on the particular call and database system. For example, the SELECT-ENDSELECT loop on the SPFLI table in our test program is mapped to a sequence PREPARE-OPEN-FETCH of physical calls in an Oracle environment.
The WHERE clause in the trace list's SQL statement is different from the WHERE clause in the ABAP statement. This is because in an R/3 system, a client is a self-contained unit with separate master records and its own set of table data (in commercial, organizational, and technical terms). With ABAP, every Open SQL statement automatically executes within the correct client environment. For this reason, a condition with the actual client code is added to every WHERE clause if a client field is a component of the searched table.
To see a statement's execution plan, just position the cursor on the PREPARE statement and choose Explain SQL. A detailed explanation of the execution plan depends on the database system in use -
Not returning from the native code

This is the exception that i am getting?? my cryptoJNIImp.c is is in the same directory as the my java file,c:\vivek work\signedcode. and i have added this to my path env variable...If u see the output, it executes the init() and then loads the Msgimpl.dll. So its got nothing do with loading a DLL. Any pointers on this..

‘iPad is disabled’ fix without resetting using iTunes
Today I met my match with an iPad that had a passcode entered too many times, resulting in it displaying the message ‘iPad is disabled – Connect to iTunes’. This was a student iPad and since they use Notability for most of their work there was a chance that her files were not all backed up to the cloud. I really wanted to just re-activate the iPad instead of totally resetting it back to our default image.
I reached out to my PLN on Twitter and had some help from a few people through retweets and a couple of clarification tweets. I love that so many are willing to help out so quickly. Through this I also learned that I look like Lt. Riker from Star Trek (thanks @FillineMachine).
Through some trial and error (and a little sheer luck), I was able to reactivate the iPad without loosing any data. Note, this will only work on the computer it last synced with. Here’s how:
1. Configurator is useless in reactivating a locked iPad. You will only be able to completely reformat the iPad using Configurator. If that’s ok with you, go for it – otherwise don’t waste your time trying to figure it out.
2. Open iTunes with the iPad disconnected.
3. Connect the iPad to the computer and wait for it to show up in the devices section in iTunes.
4. Click on the iPad name when it appears and you will be given the option to restore a backup or setup as a new iPad (since it is locked).
5. Click ‘Setup as new iPad’ and then click restore.
6. The iPad will start backing up before it does the full restore and sync. CANCEL THE BACKUP IMMEDIATELY. You do this by clicking the small x in the status window in iTunes.
7. When the backup cancels, it immediately starts syncing – cancel this as well using the same small x in the iTunes status window.
8. The first stage in the restore process unlocks the iPad, you are basically just canceling out the restore process as soon as it reactivates the iPad.
If done correctly, you will experience no data loss and the result will be a reactivated iPad. I have now tried this with about 5 iPads that were locked identically by students and each time it worked like a charm.
~~~~~~~~~~~~~
Try it and good luck. You have nothing more to lose if it doesn't work for you.

i have paid for ipages 09 on 15/05 but never succed to enter the serial code. After 45 days, altough I was charged by 20 chf, I cannot completely use all ipages tools(impossible to save ). How can I get again the serial code I paid for?
Getting the request for a serial number means that at some time you had the iWork ’09 trial installed. You need to delete the trial & then reinstall from the boxed DVD or the Mac App Store. The files to delete are the iWork ’09 folder from the main HD > Applications; the iWork ’09 folder in HD > Library > Application Support & the individual iWork application plist files found in HD > Users > (your account) > Library > Preferences for each user. The easiest way to fix the problem is to use Yvan Koenig's AppleScript that removes the files. You can find it on his box.com account in for_iWork'09 > other_iWork'09 items > uninstall iWork '09.zip. Download uninstall iWork '09.zip, decompress it, open it in AppleScript Editor and click the Run button.
Apple's support article on the subject says it's due to having a copy of the trial that is a higher version that the one you've purchased, but I'm not sure that is very common. This problem started with Snow Leopard & it seems to be some code in the iWork installers that doesn't do what it should. -

INDIAJSP and Servlets are programs/scripts that run on the server. The user/clients only sees the HTML output generated by the server. If you want to hide JavaScript from casual users then you can put the JavaScript code in a seperate file. This file can however be read from the Cache. -

How to handle multiple exceptions by the same code?
Hi, all:
In my situation I want AException and BException handled by the same code, while CException and DException handled by another code. How can I write my try-catch code in a simple way? Of course I can do the following:
public void TheMainFunction() {
try {
} catch (AException e) {
Handle_AB();
} catch (BException e) {
Handle_AB();
} catch (CException e) {
Handle_CD();
} catch (DException e) {
Handle_CD();
private void Handle_AB() {
private void Handle_CD() {
}But is there a simpler way?
Thanks in advance.If you have one or two places in your code that need multiple exceptions, just do it with multiple catch statements. Unless you are trying to write the most compact Programming 101 homework program, inventing tricks to remove two lines of code is not good use of your time.
If you have multiple catches all over your code it could be a code smell. You may have too much stuff happening inside one try statement. It becomes hard to know what method call throws one of those exceptions, and you end up handling an exception from some else piece of code than what you intended. E.g. you mention NumberFormatException -- only process one user input inside that try/catch so it is easy to see what error message is given if that particular input is gunk. The next step of processing goes inside its own try/catch.
In my case, the ArrayIndexOutOfBoundsException and
NumberFormatException should be handled by the same way.Why?
I don't think I have ever seen an ArrayIndexOutOfBoundsException that didn't indicate a bug in the code. Instead of an AIOOBE perhaps there should be an if statement somewhere that prevents it, or the algorithm logic should prevent it automatically. -
How to catch exception while validating the username and password in hbm
Hi,
I do want to set the username and password dynamically in hibernate.cfg.xml
Here below is my configuration file.
{code<hibernate-configuration>
<session-factory>
<property name="hibernate.bytecode.use_reflection_optimizer">false</property>
<property name="hibernate.connection.driver_class">oracle.jdbc.driver.OracleDriver</property>
<property name="hibernate.connection.pool_size">10</property>
<property name="show_sql">true</property>
<property name="hibernate.dialect">org.hibernate.dialect.OracleDialect</property>
<property name="hibernate.hbm2ddl.auto">update</property>
<property name="current_session_context_class">thread</property>
<property name="show_sql">true</property>
</session-factory>
</hibernate-configuration>{code}
Also im getting that session factory object like the below code.
public class Sessions { private static SessionFactory sessionFactory; private static Configuration configuration = new Configuration(); static { try { String userName = GuigenserviceImpl.userName; String password = GuigenserviceImpl.password; String hostName = GuigenserviceImpl.hostName; String portNo = GuigenserviceImpl.portNo; String sId = GuigenserviceImpl.sId; configuration .setProperty("hibernate.connection.username", userName); configuration .setProperty("hibernate.connection.password", password); configuration.setProperty("hibernate.connection.url", "jdbc:oracle:thin:@" + hostName + ":" + portNo + ":" + sId); try { configuration.configure("/hibernate.cfg.xml"); sessionFactory = configuration.buildSessionFactory(); GuigenserviceImpl.strAccpted = "true"; } catch (Exception e) { e.printStackTrace(); GuigenserviceImpl.strAccpted = "false"; } } catch (HibernateException hibernateException) { GuigenserviceImpl.strAccpted = "false"; hibernateException.printStackTrace(); } catch (Throwable ex) { GuigenserviceImpl.strAccpted = "false"; ex.printStackTrace(); throw new ExceptionInInitializerError(ex); } } public static SessionFactory getSessionFactory() { return sessionFactory; }
So, in this above scenario, suppose if im giving the wrong password means exception should be caught and the string variable "GuigenserviceImpl.strAccpted" should be assigned to false.
But im getting the SQL Exception only in console like wrong username and password. And finally i couldn't able to catch the exception in Sessions class, static block.
Anyone can help me in catching that SQL Exception in my Sessions class and i need to handle that SQL Exception in my class.

Thanks in advance.

Kothandaraman N.Hi,
Myself hardcoded that username and password checking like the below code.
String name = loginData.get("userName").toString();
String pswd = loginData.get("pswd").toString();
String hstName = loginData.get("hName").toString();
String prtNo = loginData.get("portNo").toString();
String sid = loginData.get("sId").toString();
SessionFactory sessionFactory = null;
try {
if (name.trim().equals(userName) && pswd.trim().equals(password)
&& hstName.trim().equals(hostName)
&& prtNo.trim().equals(portNo) && sid.trim().equals(sId)) {
sessionFactory = Sessions.getSessionFactory();
strAccpted = "true";
} else {
strAccpted = "false";
} catch (Exception e) {
e.printStackTrace();
strAccpted = "false";
}I have my own values in string objects, then comparing that values with the values from login form. If both values are matching, then i will do configurations in hibernate.
ResourceBundle resourceBundle = ResourceBundle
.getBundle("com.beyon.ezygui.server.Queries");
public static final String connection_url = resourceBundle
.getString("connection.url");
public static final String userName = resourceBundle.getString("userName");
public static final String password = resourceBundle.getString("password");
public static final String hostName = resourceBundle.getString("hostName");
public static final String portNo = resourceBundle.getString("portNo");
public static final String sId = resourceBundle.getString("sId");The above are the String objects i'm checking for the match with values from login form.
Thanks & Regards,
Kothandaraman N.
