I was working on a new android project on eclipse, after the running the project eclipse crashes.
I restarted my Mac and tried starting eclipse again but now it's crashes on the loading splash screen and not starting at all.

How can I make my IDE work again ?

Ok, Fixed it.
The problem was in the workspace .metadata folder (not sure where).
after using time machine to replace the folder with an older one eclipse backed to life.

Not sure, looks like you are running a new version of Java, on an older version of eclipse.
Please make sure , u are using latest versions, also update the JAVA_HOME and PATH. And try again.

Is it problematic to call dlls out of Java with another C-Runtime (msvcr90.dll) than Java (msvcr100.dll)?

I'm calling dlls out of Java using JNA.
This works most of the time, but sometimes a Memory Access Exception is thrown.
I found out that the jvm.exe runs with the msvcr100.dll and the dlls are running on the msvcr90.dll. Can this lead to problems?
Java Interface Code:
public interface FooLibInterface extends StdCallLibrary {
FltLibInterface INSTANCE = (FooLibInterface) Native.loadLibrary("C:\\dlls\\FooLibWrapper.dll", FooLibInterface.class);
NativeLong wrapedFooInterface(long id, PointerByReference inDataArray, long inItems, PointerByReference outDataArray, NativeLongByReference outItems, DoubleByReference outParX);
}
Java call:
synchronized (lock) {
long id = 123;
PointerByReference inputArray = new PointerByReference();
Memory buffer = new Memory(data.length * 8);
buffer.write(0, data, 0, data.length);
inputArray.setValue(buffer);
PointerByReference outputArray = new PointerByReference();
NativeLongByReference outItems = new NativeLongByReference();
DoubleByReference outParX = new DoubleByReference();
NativeLong excRet = ffltLib.wrapedProfileFilterInterface(id, inputArray, data.length, outputArray, outItems, outParX);
items = outItems.getValue().intValue();
double parX = outParX.getValue();
newdata = new double[ret.itemsX];
for (int x = 0; x < items; x += 1) {
newdata [x] = outputArray.getValue().getDouble(x * 8);
}
ffltLib.freemem();

Tomcat crashes when calling JNI dll in windows 7

I have a Java web application that uses tomcat 7 and that calls a JNI dll to decrypt some data using Openssl EVP.
When running on windows XP all works fine, but when I try to run it in windows 7 it crashes.

The jni dll name is : myDLL.dll
and the function is : myApp.d()
Here is the myApp.d() function in the c program that generates the dll :
JNIEXPORT jbyteArray JNICALL Java_myApp_d(JNIEnv *env, jobject obj, jbyteArray b)
{
EVP_CIPHER_CTX en, de;
// get length of bytes
int srcLen=(*env)->GetArrayLength(env, b);
//convert jbyteArray to byte []
jbyte data[srcLen];
(*env)->GetByteArrayRegion(env, b, 0, srcLen, data);
(*env)->ReleaseByteArrayElements(env, b, data , 0);
unsigned int salt[] = {12345, 54321};
unsigned char key_data[16]={ 'A','b','c','d','e','f','g','h','i','j','k','l','m','n','o','p'};
int key_data_len = 16;
if (aes_init(key_data, key_data_len, (unsigned char *)&salt, &en, &de))
{
printf("Couldn't initialize AES cipher\n");
return -1;
}
unsigned char* indata=(unsigned char*)data;
char *plaintext;
int olen, len;
int j;
char tampon[16];
for(j=0; j<16; j++)
{
tampon[j]=indata[j];
}
int desLen;
sscanf(tampon,"%d",&desLen);
unsigned char indataB[srcLen-16];
for(j=0; j<srcLen-16; j++)
{
indataB[j]=indata[16+j];
}
olen = len = srcLen-16+1;
plaintext = (char *)aes_decrypt(&de, indataB, &len);
jbyteArray bArray = (*env)->NewByteArray(env, desLen);
jboolean isCopy = JNI_TRUE;
jbyte* decrypteddata = (jbyte *)(*env)->GetByteArrayElements(env, bArray, &isCopy);
memcpy(decrypteddata, plaintext, desLen);
(*env)->ReleaseByteArrayElements(env, bArray, decrypteddata, 0);
free(plaintext);
free(decrypteddata);
EVP_CIPHER_CTX_cleanup(&en);
EVP_CIPHER_CTX_cleanup(&de);
return bArray;
(*env)->DeleteLocalRef(env, bArray );
}
This function uses these tow functions:
int aes_init(unsigned char *key_data, int key_data_len, unsigned char *salt, EVP_CIPHER_CTX *e_ctx,
EVP_CIPHER_CTX *d_ctx)
{
int i, nrounds = 5;
unsigned char key[16], iv[16];
/*
* Gen key & IV for AES 128 CBC mode. A SHA1 digest is used to hash the supplied key material.
* nrounds is the number of times the we hash the material. More rounds are more secure but
* slower.
*/
i = EVP_BytesToKey(EVP_aes_128_cbc(), EVP_sha1(), salt, key_data, key_data_len, nrounds, key, iv);
if (i != 16)
{
printf("Key size is %d bits - should be 128 bits\n", i);
return -1;
}
EVP_CIPHER_CTX_init(e_ctx);
EVP_EncryptInit_ex(e_ctx, EVP_aes_128_cbc(), NULL, key, iv);
EVP_CIPHER_CTX_init(d_ctx);
EVP_DecryptInit_ex(d_ctx, EVP_aes_128_cbc(), NULL, key, iv);
return 0;
}
unsigned char *aes_decrypt(EVP_CIPHER_CTX *e, unsigned char *ciphertext, int *len)
{
/* because we have padding ON, we must allocate an extra cipher block size of memory */
int p_len = *len, f_len = 0;
unsigned char *plaintext = malloc(p_len + AES_BLOCK_SIZE+1);
EVP_DecryptInit_ex(e, NULL, NULL, NULL, NULL);
EVP_DecryptUpdate(e, plaintext, &p_len, ciphertext, *len);
EVP_DecryptFinal_ex(e, plaintext+p_len, &f_len);
*len = p_len + f_len;
return plaintext;
}
I'm suspecting the this portion that permits to copy data from char* to jbytearray :
jbyte* decrypteddata = (jbyte *)(*env)->GetByteArrayElements(env, bArray, &isCopy);
memcpy(decrypteddata, plaintext, desLen);
(*env)->ReleaseByteArrayElements(env, bArray, decrypteddata, 0);
I tried to replace GetByteArrayElements by GetPrimitiveArrayCritical and ReleaseByteArrayElements by ReleasePrimitiveArrayCritical with no success.

[SOLVED]
As I supposed in my question, the problem was caused by the call to those tow JNI functions :
(*env)->GetByteArrayRegion(env, b, 0, srcLen, data);
(*env)->ReleaseByteArrayElements(env, b, data , 0);
I replaced them with :
jbyte* d = (*env)->GetByteArrayElements(env, b, &isCopyS);
int i;
for(i = 0; i < srcLen; i++)
{
data[i] = d[i];
}
(*env)->ReleaseByteArrayElements(env, b, d, JNI_ABORT);
Now It works both in Windows XP and Windows 7.

Fatal Error has been detected by java runtime environment.... cannot understand why?

My code is given below. Its a program that adds leaves to the database.I am getting the Fatal Error has been detected by java runtime environment and I am not understanding why. I am new to Java, so I am very confused about this. Can anybody tell me why is this happening?
I am putting up the error file as well. I tried understanding that too but couldn't find where is the error located.

"Demo" is the name of the database which has 4 columns namely empid,Fname,Lname,designation. The working of the program is that when I enter the employee ID it retrieves the remaining data from the database. As I have not added the department Id column I am not getting that from the database.

I usually see these errors when something went wrong in the JNI (Java Native Interface) code, i.e. here, perhaps the JDBC (Java DataBase Connectivity) driver ODBC32.dll. Are you sure you are using correct version of the JDBC driver for your platform? Especially check you are using 32-bit version on a 32-bit OS (Operating System) and not a 64-bit version (or vice-versa).
The crash happened outside the Java Virtual Machine in native code.

You should be using the Oracle JDBC Driver appropriate for your Oracle database version; these are typically pure Java. The JDBC-ODBC Bridge Driver has significant limitations, including JNI dependency.

C callback with JNA makes JRE crash

I'm having problems handling callbacks in JNA.
I'm trying to use a C API that uses callbacks to handle several session events (logged in, logged out, connection problem...).
The session object (called sp_session) is an opaque struct. All the callbacks are registered in a sp_session_callbacks structure. According to the API, I am supposed to declare the callbacks object, and put it into a Config object that I will provide when creating the sp_session object. If I don't want to use certain callbacks, I am supposed to initialize them with null. The API is using the __stdcall calling convention.
Here is a snippet of the C header that's relevant to my problem:
#define SP_CALLCONV __stdcall
typedef struct sp_session sp_session; ///< Representation of a session
typedef enum sp_error {
SP_ERROR_OK = 0,
SP_ERROR_BAD_API_VERSION = 1,
/* More errors */
} sp_error;
typedef struct sp_session_callbacks {
/**
* Called when login has been processed and was successful
*/
void (SP_CALLCONV *logged_in)(sp_session *session, sp_error error);
/**
* Called when logout has been processed. Either called explicitly
* if you initialize a logout operation, or implicitly if there
* is a permanent connection error
*
* #param[in] session Session
*/
void (SP_CALLCONV *logged_out)(sp_session *session);
/**
* Called when there is a connection error, and the library has problems
* reconnecting to the Spotify service. Could be called multiple times (as
* long as the problem is present)
*/
void (SP_CALLCONV *connection_error)(sp_session *session, sp_error error);
/* More callbacks */
} sp_session_callbacks;
/**
* Initialize a session. The session returned will be initialized, but you will need
* to log in before you can perform any other operation
*/
SP_LIBEXPORT(sp_error) sp_session_create(const sp_session_config *config, sp_session **sess);
Here is my equivalent JNA code:
The sp_session object
public class sp_session extends PointerType{
public sp_session(Pointer address) {
super(address);
}
public sp_session() {
super();
}
}
The sp_session_callbacks object, containing all the callbacks
public class sp_session_callbacks extends Structure{
public LoggedIn logged_in;
public LoggedOut logged_out;
public ConnectionError connection_error;
}
The callbacks object (here is LoggedIn, but of course I have one for each callback)
public interface LoggedIn extends StdCallCallback {
public void logged_in(sp_session session, int error);
}
The native library, with the declaration of all the methods
public interface JLibspotify extends StdCallLibrary{
int sessionCreate(sp_session_config config, PointerByReference sess);
int sessionLogin(sp_session session, String username, String password);
// All the other methods defined by the API
}
And my main class, binding it all together
public class Test{
static{
System.loadLibrary("libspotify");
}
public static void main(String[] args){
JLibspotify lib = (JLibspotify)Native.loadLibrary("libspotify", JLibspotify.class);
sp_session_config cfg = new sp_session_config();
}
sp_session_callbacks sessCallbacks = new sp_session_callbacks();
LoggedIn loggedInCallback = new LoggedIn(){
public void logged_in(sp_session session, int error) {
System.out.println("logged_in() called");
}
};
sessCallbacks.logged_in = loggedInCallback;
cfg.session_callbacks = sessCallbacks;
PointerByReference sessionPbr = new PointerByReference();
int error_id = sessionCreate(cfg, sessionPbr); // CRASHES HERE
sp_session mySession = new sp_session(sessionPbr.getValue());
}
}
So, the sessionCreate function call makes the JRE crash with the trace at the end of the post EXCEPTION_ACCESS_VIOLATION (0xc0000005) problematic frame: C [jna3666290841889849729.dll+0xa3f4].
It looks like the logged_in callback is causing this, because when I set it to null it runs ok. Plus, if I initialize the connection_error callback, that has the exact same signature, it doesn't crash either.
I'm running version 3.2.7 of JNA. I tried with an anterior version (3.0.9) and it also failed.
I'm running the JDK 1.7 beta version, but I tried with the 1.6 and it also failed.
Thank you!

When I run it like this (without callbacks), the output is:
Creating session
Login
And when I register the callbacks (uncomment the lines), it doesn't even print anything!
It looks like it doesn't print anything when a callback is called, because if I comment the sp_session_login line, only the declaration of notify_main_thread (which is the only one printed) will prevent the program from printing...

When you have a C structure like:
struct Foo {
Bar* bar
}
i.e. one which contains a pointer to another structure, your JNA implementation of Bar (class Bar extends Structure) must also implement the Structure.ByReference interface -- otherwise JNA will think that struct Foo contains an instance of struct Bar instead of a pointer to a struct Bar, and an illegal memory access will result as the C code interprets a value in the Bar instance as a pointer.
You need to add implements Structure.ByReference to the sp_session_callbacks class.
Thanks for inspiring me to look at JNA -- it's pretty cool!

Here's a C program which does the same thing (with fewer callbacks -- you'll need to add more). It's for OS X so you may need to change the #include. As I can't get spotify in Australia I can't test it to see whether a successful login hits a callback, but the logging callback works.
#include <stdio.h>
#include <libspotify/api.h>
void SP_CALLCONV log_message(sp_session *session, const char *data) {
fprintf(stderr,"log_message: %s\n", data);
fflush(stderr);
}
void SP_CALLCONV connection_error(sp_session *session, sp_error error) {
fprintf(stderr,"connection_error: %d\n", error);
fflush(stderr);
}
int main(int argc, char** argv) {
static byte APP_KEY[] = {
/*the API key */};
static sp_session_callbacks callbacks;
callbacks.log_message = log_message;
callbacks.connection_error = connection_error;
static sp_session_config cfg;
cfg.callbacks = &callbacks;
cfg.api_version = 7;
cfg.cache_location = ".";
cfg.settings_location = ".";
cfg.user_agent = "jspotify";
cfg.application_key = APP_KEY;
cfg.application_key_size = sizeof(APP_KEY);
sp_session* mySession;
int code = sp_session_create(&cfg, &mySession);
printf("sp_session_create returned %d\n", code);
sp_session_login(mySession, "foo", "bar");
printf("sp_session_login returned %d\n", code);
sleep(10);
}
If the C program calls callbacks which the Java version doesn't, then perhaps there's something wrong with the use of jna -- if not, perhaps there's something more to understand about spotify and when it calls callbacks. I agree that the docs seem to say that a successful login will call a callback, but perhaps they're out of date?
