hi , i am able to pass the data to the applet through the StringBuffer Object .Here is the JSP code which does the same :
[ code ]
<%
int len =0;
StringBuffer data = new StringBuffer();
String ginfo = new String();
if (r1>r2)
loop:
while(sub2.next()){
while( sub1.next()){
if(sub1.getString(1).equals(sub2.getString(1))){
ginfo = sub1.getString(1)+"@"+ sub1.getString(2)+"@"+sub1.getString(3)+"@"+ sub2.getString(3)+"@"+sub1.getString(4);
data.append(ginfo);
data.append("\n");
len++;
sub1.beforeFirst();
continue loop;
sub1.beforeFirst();
else
loop1:
while(sub1.next()){
while( sub2.next()){
if(sub2.getString(1).equals(sub1.getString(1))){
ginfo = sub1.getString(1)+"@"+ sub1.getString(2)+"@"+sub1.getString(3)+"@"+ sub2.getString(3)+"@"+sub1.getString(4);
data.append(ginfo);
data.append("\n");
len++;
sub2.beforeFirst();
continue loop1;
sub2.beforeFirst();
sub1.close();
sub2.close();
%>
<jsp:plugin type="applet" code="Dot.class" width="500" height="500" align="center">
<jsp:params>
<jsp:param name="sub1" value="<%=s1%>" />
<jsp:param name="sub2" value="<%=s2%>" />
<jsp:param name="max" value="<%=max%>"/>
<jsp:param name="len" value="<%=len%>"/>
<jsp:param name="data" value="<%=data%>"/>
</jsp:params>
<jsp:fallback>
Plugin tag OBJECT or EMBED not supported by browser, So please Download and Install the Plugin
</jsp:fallback>
</jsp:plugin>
But the problem is ..the applet doesn't paint. the applet code is :
double interval,xinterval1,yinterval1;
double max;
int len ;
private String message = "Initializing";
int x =0,i=0;
String sub1,sub2,data;
public void init() {
sub1=getParameter("sub1");
sub2=getParameter("sub2");
max = Double.valueOf(getParameter("max")).doubleValue();
data = getParameter("data");
len = Integer.parseInt(getParameter("len"));
interval = max/5;
public void paint (Graphics g){
String [][]xyf = new String [len][5];
StringTokenizer tokenizer = new StringTokenizer(data);
while(tokenizer.hasMoreTokens()){
String valueOne = tokenizer.nextToken();
StringTokenizer singleginfo = new StringTokenizer(valueOne,"@");
x=0;
while (singleginfo.hasMoreTokens()) {
xyf[x++]=singleginfo.nextToken();
i++;
[/ code ]
Can please tell me whats wrong with this ...
