I'm trying to send an email using a javascript code in a Java project. Database connection works fine, I already tested it. I got the error:
javax.script.ScriptException: sun.org.mozilla.javascript.internal.EvaluatorException: missing ) after formal parameters (#1) in at line number 1
The only information of relevance is not readily reported: the final JavaScript string executed. Make sure to look at relevant data when debugging. After inspecting the final string it will be apparent why it is incorrect and trivial to "fix".
Hint: it will look something like function sendMail(userblah, foo#bar.qux) { .., which is indeed invalid JavaScript.
The problem and solution should be self-evident from that - use fixed parameters (variable names) in the function declaration and supply arguments (values) via the invokeFunction call.
Solution:
// The following parameter names are JAVASCRIPT variable names.
String script = "function sendMail(username, email, body) { ..";
// And pass correct arguments (values), in order. The variables used
// here are JAVA variables, and align by-position with the JS parameters.
inv.invokeFunction("sendMail", username, email, "EMAIL SENT!!!!");
In addition, the getElementById (invalid ID) is wrong, the body parameter is never used, and encodeURIComponent should be used (instead of escape).
Not sure if this is a typo or not:
result = request.executeQuery("SELECT user.login, user.email "
+ "FROM user " + );
It looks like you are missing the end of your statement.
Hmmmm, your function definition:
function sendMail("username","email") {...}
doesn't look like valid JavaScript to me, apart of that, you never call the function.
Pseudocode, how to do it:
function sendMail(username, email) {
var link = "jadajada" + email; // .... etc
}
sendMail("+username+","+email+");

I inherited some old Cocoon code, if it's obvious, please tell me where in the docs I could find it.
I have a function to clean up some page parameters. I want to hand over the content to that function, but I can't manage to get there.
This is the original code, the value must pass my "cleanPath" function.
<jdbp:page-param name="pageToLoad" value="${{request.requestURI}}/../{#page}"/>
Attempt 1:
<jdbp:page-param name="pageToLoad" value="cleanPath(${{request.requestURI}}/../{#page})"/>
My attempt was to add the function in and leave everything like that, but it's not working.
My next attempt is these nice xsp:logic blocks, where I can't get the requestURI. "request.requestURI" is unknown, evaluate complains
"Type mismatch: cannot convert from Object to String".
<xsp:logic>
String input2 = evaluate("${{request.requestURI}}", String.class);
String input = "/../<xsl:value-of select="#page"/>";
putVariable("Hase","Test "+input);
</xsp:logic>
<jdbp:page-param name="pageToLoad" value="${{request.requestURI}}/../{#page}"/>
<jdbp:page-param name="Hase" value="${{Hase}}"/>
It's easy to just call request.getRequestURI();. No need for complicated wrappers.
How can i send an Array with a HTTP Get request?
I'm Using GWT client to send the request.
I know this post is really old, but I have to reply because although BalusC's answer is marked as correct, it's not completely correct.
You have to write the query adding "[]" to foo like this:
foo[]=val1&foo[]=val2&foo[]=val3
That depends on what the target server accepts. There is no definitive standard for this. See also a.o. Wikipedia: Query string:
While there is no definitive standard, most web frameworks allow multiple values to be associated with a single field (e.g. field1=value1&field1=value2&field2=value3).[4][5]
Generally, when the target server uses a strong typed programming language like Java (Servlet), then you can just send them as multiple parameters with the same name. The API usually offers a dedicated method to obtain multiple parameter values as an array.
foo=value1&foo=value2&foo=value3
String[] foo = request.getParameterValues("foo"); // [value1, value2, value3]
The request.getParameter("foo") will also work on it, but it'll return only the first value.
String foo = request.getParameter("foo"); // value1
And, when the target server uses a weak typed language like PHP or RoR, then you need to suffix the parameter name with braces [] in order to trigger the language to return an array of values instead of a single value.
foo[]=value1&foo[]=value2&foo[]=value3
$foo = $_GET["foo"]; // [value1, value2, value3]
echo is_array($foo); // true
In case you still use foo=value1&foo=value2&foo=value3, then it'll return only the first value.
$foo = $_GET["foo"]; // value1
echo is_array($foo); // false
Do note that when you send foo[]=value1&foo[]=value2&foo[]=value3 to a Java Servlet, then you can still obtain them, but you'd need to use the exact parameter name including the braces.
String[] foo = request.getParameterValues("foo[]"); // [value1, value2, value3]
I sent one request as URL with data to servlet, But by default servlet is modifying the data and sending as request. Can you please suggest how to maintain the request URL with data which i passed to servlet should remain same ?
Example:- when i am passing the data to servlet
http://localhost/helloservlet/servlet/ppd.abcd.build.coupons.CouponValueFormatterServlet?dsn=frd_abc_abcde&lang=ENG&val=PRCTXT|12345 &ABCDEFG
when it using the above url in servelt as request , like string abc = request.getParameter("val"), the val attribute is trimmed automatically and assigned as " val=PRCTXT|12345" but it supposed to be like " val = PRCTXT|12345 &ABCDEFG ". Please help me on this.
The servlet interprets each & in the URL as the start of a new parameter. So when it sees &ABCDEFG, it thinks you are sending a new parameter called ABCDEFG with no value (though this is technically a "keyless value" according to the specifications).
Two things to fix this, first is when you want to actually send an &, use %26 instead. This will be skipped by the code that divides up the parameters, but converted to a real & in the parameter's value.
Second is to replace spaces with +. Spaces in URLs work sometimes but can be problematic.
So your actual request URL should look like this:
http://localhost/helloservlet/servlet/ppd.abcd.build.coupons.CouponValueFormatterServlet?dsn=frd_abc_abcde&lang=ENG&val=PRCTXT|12345+%26ABCDEFG
If you're building these parameters in javascript, you can use encodeURIComponent() to fix all problem characters for you. So you could do something like this:
var userInput = *get some input here*
var addr = 'http://www.example.com?param1=' + encodeURIComponent(userInput);
I am running the following code (Java selenium client)- PAGE_NUMBER has a value, but I am unable to get it using selenium:
String script = "var cellValue = selenium.browserbot.getUserWindow().PAGE_NUMBER;";
selenium.runScript(script);
String value = selenium.getEval("selenium.browserbot.getUserWindow().cellValue;");
System.out.println("Value: " + value);
I don't know Selenium 1 at all and Selenium2/Webdriver is very different. However there are three things that I suspect to play a role in this issue:
Scope: You declared the variable as local to the scope of the script (by writing var). You might try using a global variable by omitting the var keyword, so that you can access it later.
Why do you try to access the variable via selenium.browserbot.getUserWindow().. Try omitting this part.
The semicolon after cellValue is probably no good idea either
And then again, why not simply using
String value = selenium.getEval("selenium.browserbot.getUserWindow().PAGE_NUMBER");
?
I hope at least some part of this answer helps you. As I said I am just guessing.
I am working with a java generated dynamic webpage, and I'm printing links from a query to a JDO. But I don't understand how can I get and use the parameter from the url.
My html objects are printed like this
print = print + "Nome:<a href='displayFotos?album="+results.get(i).nome+ "'>"+
results.get(i).nome+ "</a></br>";
The results in having for example:
Nome:<a href='displayFotos?album=album1'>album1</a>
So, in my head when clicked it should be calling the address of the dynamic webpage album like this and should get the parameter. In this case it would be the album1.
else if (address.indexOf("/dinamicas/album") != -1) {
String album = param1;
System.out.println("did it work? "+album);
}
And I have in the beginning of the class a general parameter that I use to get text from html forms.
String param1 = req.getParameter("param1");
I understand this might be an easy question but I'm not getting there by myself.
Nome:<a href='displayFotos?album=album1'>album1</a>
Here, you're using a parameter name of album.
However, you're attempting to get it by a parameter name of param1. This does obviously not match.
String param1 = req.getParameter("param1");
You need to use the same parameter name as is been definied in the request.
String album = req.getParameter("album");
// ...
