cannot find symbol method append (String)

I don't get it why it says it cannot find symbol append.
do i need to use Stringbuffer? i got this code on a tutorial for receipts from youtube, and the uploader disabled comments so I can't ask him directly. please help me. Im still an amateur at java.
Tell me if I need to post my whole code or what code would you want to see to see errors. thanks in adv.
Calendar timer = Calendar.getInstance();
timer.getTime();
SimpleDateFormat tTime = new SimpleDateFormat("HH:mm:ss");
tTime.format(timer.getTime());
SimpleDateFormat Tdate = new SimpleDateFormat("dd-MMM-yyyy");
Tdate.format(timer.getTime());
jtxtReceipt.append("\ Water Station Receipt:\n" +
"Reference:\t\t\t" + refs +
"\n=========================================\n" +
"Mineral:\t\t\t" + jtxtMineral.getText() + "\n\n" +
"Purified:\t\t\t" + jtxtPurified.getText() + "\n\n" +
"Travel:\t\t\t" + jtxtTravel.getText() + "\n\n" +
"VAT:\t\t\t" + jtxtVat.getText() + "\n"+
"\n========================================\n" + "\n" +
"Tax:\t\t\t" + jtxtTax2.getText() + "\n" +
"Subtotal:\t\t\t" + jtxtSubTotal.getText() + "\n" +
"Total:\t\t\t" + jtxtTotal.getText() + "\n" +
"===========================================" +
"\nDate:" + Tdate.format(timer.getTime()) +
"\ntTime:" + tTime.format(timer.getTime()) +
"\n\t\tThank you ");

The append method doesn't exist in the String class. You can either user a StringBuilder to do the job, or if it's a light concatenation, just use the + operator

The append method doesn't work on TextField Palette. So, if You're on TextField Palette, replacing that with TextArea Palette should solve the problem.

Convert Loadrunner File Parameter to Java string for payload

I have a java virtual user script that is sending a payload request. I am trying to use values from a file to send via a loadrunner file parameter.
here is the payload:
private static final String PAYLOAD =
"<ips_cad_mdt>\n" +
" <SignOnRequest>\n" +
" <DestApplication>hhhh</DestApplication>\n" +
" <OrigApplication>hhh</OrigApplication>\n" +
" <SessionRef>3</SessionRef>\n" +
" <Aliasing>1234</Aliasing>\n" +
" </SignOnRequest>\n" +
"</ips_cad_mdt>";
I would like to use something like the following:
private static final String PAYLOAD =
"<ips_cad_mdt>\n" +
" <SignOnRequest>\n" +
" <DestApplication>hhh</DestApplication>\n" +
" <OrigApplication>hhh</OrigApplication>\n" +
" <SessionRef>3</SessionRef>\n" +
" <Aliasing>”+lr.eval_string(“{AliasId}”)+”</Aliasing>\n" +
" </SignOnRequest>\n" +
"</ips_cad_mdt>";
for some reason i cant see any output for this value. do i need to declare a variable: e.g. lr.save_string("AliasId", "{AliasId}");
an example of this would help loads. Many Thanks

There seems to be an error in the code completion in VuGen. The parameters should be reversed and without the {} in save_string.
lr.save_string("1234","myId");
lr.message(lr.eval_string("{myId}"));
In the documentation it is correct - https://admhelp.microfocus.com/lr/en/12.55/help/function_reference/FuncRef.htm#FuncRef/c_vuser/lrFr_lr_save_string.htm?Highlight=lr_save_string
I asked the responsible team to fix the code completion in VuGen so you will be able to see this change in one of the future releases.

SOAP client SAAJ

I am relatively new to SOAP and wanted to write a SOAP client in JAVA. I figured out that the WSDL has a lot of other crap and as I use just one service out of it, hence SAAJ would be the shortest way. The first WSDL I got was RPC encoded and did not support SSL connections (http link). The call I made was this:
String request = "<soapenv:Envelope xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" xmlns:soapenv=\"http://schemas.xmlsoap.org/soap/envelope/\" xmlns:urn=\"urn:AxessInterface\">"
+ " <soapenv:Header/>"
+ " <soapenv:Body>"
+ " <urn:getModemFromACS soapenv:encodingStyle=\"http://schemas.xmlsoap.org/soap/encoding/\">"
+ "<ModemIDMACAddressChoice xsi:type=\"urn:ModemIDMACAddressChoiceStruct\">"
+ " <ModemID xsi:type=\"xsd:string\">"
+ modemId
+ "</ModemID>"
+ " </ModemIDMACAddressChoice>"
+ " </urn:getModemFromACS>"
+ " </soapenv:Body>"
+ "</soapenv:Envelope>";
The new WSDL that I have is I guess NOT RPC encoded (it does not have that "style=rpc" tag anywhere) and the link is SSL enabled (https with one way authentication). The style is "document" in this WSDL.
I have a couple of issues:
My soap call doesnt work. I modified it to be:
String request = "http://www.w3.org/2001/XMLSchema-instance\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" xmlns:soapenv=\"http://schemas.xmlsoap.org/soap/envelope/\" xmlns:urn=\"urn:AxessInterface\">"
+ " "
+ " "
+ " "
+ " "
+ " "
+ modemId
+ ""
+ " "
+ " "
+ " "
+ "";
I am not sure why the code cannot be displayed, i removed the line "soapenv:encodingStyle=\"http://schemas.xmlsoap.org/soap/encoding/\" . With this i get a SOAPFault with message: "list index out of range"
Can someone tell me how to add that truststore to my SOAP client? (I use System.setProperty but I am not sure if this is the best way to go).

How can I split the data over multiple lines in a JTextArea?

How can I put each line of the host in the message body? I work with a JTextArea.
String host = InetAddress.getLocalHost().getHostName().toString();
texto_recepcion.setText(host + texto_recepcion.getText() + dpRecepcion.getAddress() + " " + mensaje_recibido + "\n");
How it is now:

I resolve my question with append function.
String host = InetAddress.getLocalHost().getHostName().toString();
texto_recepcion.append(host); // ***Use the function append for solve the problem***
texto_recepcion.setText(texto_recepcion.getText() + dpRecepcion.getAddress() + " " + mensaje_recibido + "\n");
Thanks a lot

Why don't you add the newline character "\n" to the beginning of the string?
texto_recepcion.setText("\n" + host + texto_recepcion.getText() + dpRecepcion.getAddress() + " " + mensaje_recibido);

Determining Base URL using JSP

In the browser (IE and Firefox) if you have a relative link and your URL is: http://domain/somepath/lastfolder/
the relative link becomes:
http://domain/somepath/lastfolder/linkdocname.html
if the URL is http://domain/somepath/lastdoc the relative link becomes:
http://domain/somepath/linkdocname.html
http://domain/somepath/lastfolder/ becomes:
http://domain/somepath/lastfolder/linkdocname.html
Is there a way to replicate this using JSP without writing a special function?
I tried to get the base URL using:
baseURL = request.getScheme() + "://" + request.getServerName() + ":"
+ request.getServerPort()+ request.getRequestURI();
but that gets me the whole path of the requst URI and doesn't drop off the last bit if it doesn't end in a "/" Then if I try:
baseURL = request.getScheme() + "://" + request.getServerName() + ":"
+ request.getServerPort() + request.getContextPath();
that gives me everything up to the web container folder but not any of the folders after that.

In your last string building attempt you are missing a port number, even though you specified ":"
Try this:
new URL(request.getScheme(), request.getServerName(),
request.getServerPort(), request.getContextPath());
You can also build the string yourself and remove default ports if needed:
public String getBaseUrl(HttpServletRequest request) {
if (( request.getServerPort() == 80 ) || ( request.getServerPort() == 443 )) {
return request.getScheme() + "://" + request.getServerName() +
request.getContextPath();
} else {
return request.getScheme() + "://" + request.getServerName() + ":" +
request.getServerPort() + request.getContextPath();
}
}
