Network programming C and Java

Question

Hi
I'm new to writing client/server programs.
I have a solaris box and I have a server written in C.
I like to write a java client to talk to the server.
Are there web sites here or elsewhere that would show
examples of that ?
FULLY Appreciate any help.

thanks for your response.
I dont quite understand what u mean by definition.
Do you mean the C struct of the message sent ?
DMINT32 is the regular primitive data type
long int
my C server header file contains:
extern struct empm_rec_struct {
     DMINT32 ml;
     DMINT32 lm;
     DMINT32 mm;
     DMINT32 boolean;
     DMINT32 rollover;
} current_empm_rec;
struct empm_rec_struct temp_empm_rec;
/* struct to send to client */
extern struct MsgStruct {
     struct empm_rec_struct msg_rec;
     DMINT32          index;
struct MsgStruct msgStruct;
I then tried sending this struct with send( ):
eg:
i = sprintf(str, "msgstruct ml %d\n",msgStruct.msg_rec.ml);
          if (send(new_fd,str, 10, 0) == -1)
     perror("send");
but my java client only show:
msgstruct
that's why I need an example like mine where the java client sends a "pulse"
to the server, server sends the struct msg and then client prints them out.
