I get this error message
pageContext cannot be resolved
but I have no variable pagecontext.
This is the code (I know there are other problems here that are beyond the scope of this question):

I think this is because of having scriplets in your JSP. You might have some scriptlet which is not closing the block properly.
Or could be some of your jspf's are is not having proper braces. Look at your generated Java code and debug where it has gone wrong.
Using Java code inside JSP should be avoided to get rid of these kind of problems. Java code should be put in Sevlets and EL should be used in JSP's.

I have a problm with update link for updating my transaction. At one jsp I have a list with transactions, and after pressing Update" which is link i wanted to pass transactionId, update it, save and get back to list. I've used c:param hidden and it doesnt work. I have no idea why it doesnt pass id and autofill forms. It seems like values are passed in session when ive clicked testing transaction:
http://localhost:8080/transaction/addTransaction?transactionId=64&userId=1
Here is transaction Controller:
#Controller
#RequestMapping("/transaction")
public class TransactionController {
#Autowired
TransactionService transactionService;
#Autowired
CategoryService categoryService;
#Autowired

#GetMapping("/addTransaction")
public String transactionsList(Model theModel){
Transaction transaction = new Transaction();
theModel.addAttribute("user",userService.getAllUsers());
theModel.addAttribute("category", categoryService.getAllCategories());
theModel.addAttribute("newTransaction", transaction);
return "addTransaction";
}
#PostMapping("/saveTransaction")
public String saveTransaction(#ModelAttribute("newTransaction") Transaction
newTransaction,
BindingResult theBindingResult,
HttpServletRequest request) throws
ParseException {
DateTimeFormatter formatter = DateTimeFormatter.ofPattern("yyyy-MM-dd");
String date = request.getParameter("transactionDate");
LocalDate localDate = LocalDate.parse(date, formatter);
Date formatedDate =
Date.from(localDate.atStartOfDay().toInstant(ZoneOffset.ofHours(-3)));
newTransaction.setTransactionDate(formatedDate);
transactionService.saveTransaction(newTransaction);
return "redirect:/user/userPage";
}
#GetMapping("/deleteTransaction")
public String deleteUser(#RequestParam("transactionId") int idFromTransactionToDelete,
#RequestParam("userId") int loggedUserId,
RedirectAttributes redirectAttributes){
transactionService.deleteTransactionById(idFromTransactionToDelete);
User loggedUser = userService.getUserById(loggedUserId);
redirectAttributes.addFlashAttribute("loggedUser", loggedUser);
return "redirect:/user/userPage";
}
#GetMapping("/updateTransaction")
public String updateUser(#RequestParam("transactionId") int
idFromTransactionToUpdate,
#RequestParam("userId") int loggedUserId,
RedirectAttributes redirectAttributes,
Model theModel){
Transaction transactionToUpdate = transactionService.getSingleTransactionById(idFromTransactionToUpdate);
transactionToUpdate.setUser(userService.getUserById(loggedUserId));
theModel.addAttribute("newTransaction",transactionToUpdate);
theModel.addAttribute("category", categoryService.getAllCategories());

Problem seems to be in your code. You have defined in jsp:
<c:url var="updateTransactionLink"
value="/transaction/addTransaction">
while in java code:
#GetMapping("/updateTransaction")
public String updateUser(#RequestParam("transactionId") int
In JSP Change it to :
<c:url var="updateTransactionLink"
value="/transaction/updateTransaction">

if ( id != null ) {
String desc = request.getParameter("desc");

I encountered this error while working on a web application for google app engine,through this tutorial.http://www.vogella.com/tutorials/GoogleAppEngineJava/article.html. Would like to hear more advice from you. Thank you.

I built and ran the very good Google App Engine Tutorial for Java (Todo list with JPA) with no problems at all. The platform was GAE SDK 1.8.9, Eclipse 3.8, OpenJDK 7u21 and Debian Testing (jessie). This result verifies the correctness of all the tutorial source code. Your problem is somewhere in your local installation.
Probably, the instance returned by your dao.getTodos method, is not from a class that implements java.util.List interface.
The line
34: todos = dao.getTodos(user.getUserId());
clobbers the reference to ArrayList assigned earlier to todos. Instead try
todos.addAll( dao.getTodos(user.getUserId()) );
I am using org.apache.commons.*, org.apache.commons.disk.*, org.apache.commons.fileupload.servlet.* packages for file uploading in JSP program and there was no need of Struts and it was working great, data easily worked with this, but when I added Struts 2 core libraries into my web project using MyEclipse 8.5 it is not working and have no fields found. May be the program is with upload.parseRequest.
Frankly, I am unable to understand the problem, so I share my program too

The best thing is to rewrite the JSPs to remove scriptlets and move business logic to the action classes.
You could also use Struts2 <s:if> and <s:else> tags to render content conditionally.
The commons-fileUpload is the default implementation for uploading files in Struts2, to use it correctly you could run an example Struts2 project like struts-2-upload-multiple-files-example.
Im getting a curious error with an ArrayList, below is the code (note that this code was copied from an online servlet example, I am a JAVA novice).
the JSP:
<%#page import="p.SecondExample"%>
<%# page language="java" import="java.util.*;"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<HTML>
<HEAD>

<script language="javascript">
function editRecord(id){
window.location.href="editServlet/"+id;
}
function deleteRecord(id){
window.location.href="deleteUser/"+id;
}

in debug, the error appears to occur with:
viewList = (ArrayList)itr.next();
int id = Integer.parseInt(viewList.get(0).toString());
viewItr = viewList.iterator();
where my error appears as:
org.apache.jasper.JasperException: java.lang.ClassCastException: java.lang.String cannot be cast to java.util.ArrayList
I'm not quite sure why or how to make next a string. Any help is greatly appreciated.
Yep, itr.next() returns a String, which cannot be cast into an ArrayList.
String value = (String) itr.next();
int id = Integer.parseInt(value);
The following few lines of code in which you're iterating over your viewArray can be removed now, too.
