Hi,
The below is the code for the same
#include <ctype.h>
#include <stdio.h>
#include <string.h>
#include <apr_general.h>
#include <apr_getopt.h>
#include <apr_file_io.h>
#include "svn_base64.h"
#include "svn_quoprint.h"
#include "svn_pools.h"
#include "svn_delta.h"
#include "svn_error.h"
#include "svn_ra.h"
#include "svn_string.h"
#include <jni.h>
#include "svnserver_SVNSession.h"
JNIEXPORT jstring JNICALL
Java_svnserver_SVNSession_displayHelloWorld( JNIEnv *env, jobject obj,
jstring data_str )
{
svn_stream_t *stdout_stream;
svn_txdelta_stream_t *txdelta_stream;
svn_txdelta_window_handler_t svndiff_handler;
svn_string_t *encoder;
svn_stringbuf_t * src_buf;
svn_stringbuf_t * tgt_buf;
void *svndiff_baton;
apr_pool_t *pool;
apr_initialize();
pool = svn_pool_create (NULL);
src_buf = svn_stringbuf_create( "h", pool );
tgt_buf = svn_stringbuf_create( "", pool );
svn_txdelta (&txdelta_stream,
svn_stream_from_stringbuf( src_buf, pool ),
svn_stream_from_stringbuf( tgt_buf, pool ),
pool);
//err = svn_stream_for_stdout (&stdout_stream, pool);
// I am not sure what should be given here( above or the below statement
) as I should give a string back to // java program so that it can
convert it into bytes and send it the message // across.
txdelta_stream = svn_stream_from_stringbuf( &src_buf,
pool);
encoder = svn_base64_encode_string(
svn_string_create("h\0",pool), pool );
printf("encoded data:: %s$\n",encoder->data);
svn_txdelta_to_svndiff (encoder, pool, &svndiff_handler,
&svndiff_baton);
err = svn_txdelta_send_txstream (txdelta_stream,
svndiff_handler,
svndiff_baton,
pool);
return (*env)->NewStringUTF(env, encoder->data);
}
I am unable to return the exact string/byte that is required by the
client.
Can you please tell me how to do it?
Thanks and regards
Ramprasad

Why are you trying to re-implement the whole binary differencing
language? Why not just use the public API for encoding/decoding
binary differences as provided by the public API in svn_delta.h?
Wouldn't it be easier to make JNI calls to libsvn_delta, rather than
reimplement everything?
