  • Unable to compile class for JSP.       package not found

    Hello folks,

  • J2EE app server not able to compile JSP

    Hi,
    I have just installed J2EE app server and am trying to deploy a JSP. The following error is generated. can anyone help me please.
    Thank you,
    Deepika.
    org.apache.jasper.JasperException: Unable to compile class for JSP
    No Java compiler was found to compile the generated source for the JSP.
    This can usually be solved by copying manually $JAVA_HOME/lib/tools.jar from the JDK
    to the common/lib directory of the Tomcat server, followed by a Tomcat restart.
    If using an alternate Java compiler, please check its installation and access path.

         org.apache.catalina.security.SecurityUtil.doAsPrivilege(SecurityUtil.java:200)

    This is a known issue.
    Here's an explanation of the behaviour you are seeing:
    The misleading error message is printed only in the case where a javac
    compilation error line number cannot be mapped back to a line number
    in the JSP source code.
    The internal representation of a JSP element ("JSP node") in the JSP compiler
    contains the following info:
    - The begin line number of the JSP element in the JSP page
    - The begin and end line numbers ("range") of the Java code that was
    generated for the JSP element
    When attempting to map a javac error line number back to the JSP
    source line, we determine the range into which the javac error line
    number falls, and retrieve the JSP source number of the JSP element
    associated with that range.
    However, in some cases, it is impossible to trace a javac error line
    number back to the JSP element that caused the error. For example,
    consider the following scriptlet:
    <%
    String query = request.getParameter("query");
    if(query != null) {
    out.println(query);
    } else {
    out.println("(null)");
    // } // <-- !Missing brace syntax error
    %>
    Since the JSP compiler wraps the generated code into a
    try-catch-finally block, the above syntax error in the scriptlet
    causes havoc with that try-catch-finally block, and results in 3 javac
    errors:
    <file>jsp.java:<line1>: 'catch' without 'try'
    } catch (Throwable t) {
    ^
    <file>jsp.java:<line2>: 'try' without 'catch' or 'finally'
    try {
    ^
    <file>jsp.java:<line3>: '}' expected
    Notice that all of the above javac error numbers are outside the range
    of the java line numbers corresponding to the scriptlet that caused the
    error, and therefore cannot be mapped back to any line numbers in the
    JSP page source.
    AS 8.0 PE does not handle this case correctly, and prints out the
    misleading error message (though the real error message can be found
    in the server log).
    Notice that this problem is going to be fixed in AS 8.1, so that if a
    javac error line number cannot be mapped back to a JSP page line
    number, the javac error is still returned to the client.
    In AS 8.0 PE, you need to check your server log to find out why the compilation failed.
    If you still have any problems, send me your JSP, and I will take a look at it.
    Thanks,
    Jan

    just a random guess...
    I had a ton of issues with JBoss and jfreechart. JBoss uses a different classloader, and its internal versions of the jfreechart classes will be loaded before yours, causing all sorts of issues. Dig through the jboss directories and you'll find a different, older version of jfreechart of one of its classes. Remove them and you'll be in better shape.
    Alternatively, look around the JBoss docs for how to disable/turn off the unified classloader for your app (its a directive in jboss-web.xml IIRC). This should make the classloader for your webapp perform to spec, getting rid of the class colission issues.

  • Unable to compile class for JSP

    Please can anyone help me to solve this.
    Actually,this is the condition.
    In my db,there is a table called UserPassword, which has 4
    fields(empNo,UserName,password,level). Now I want to do these things:
    When the user submits the data to create a new account via HTML form, it submits the data to the file called CreateAcc.jsp. In this file it perform some logic,here are they.
    1)To check the empNo,if it is already exist in the DB,
         if empNo =exist then display error.(record already exist)
         if empNo =notexist then do task 2).
    2)check the UserName,if it is already exist in the db,
         if UserName=exist then display error.(because it's a primary key)
         if UserName=notexist then do task 3).
    3)Create a new user account and save it to the db.
    To do these tasks,I never create a new objects for the tasks 1) and 2).
    only for task 3)create an object.
    Is it the right way?
    Here is the file CreateAcc.jsp

    Are there any mistakes? If so tell me where is it and how to change them.Please help.

    I try it that way, but it don't compile.
    Error:core\data\UserPassword.java:package javax.servlet does not exist
    import javax.servlet.*;
    core\data\UserPassword.java:package javax.servlet.http does not exist
    import javax.servlet.http.*;
    So,I comment them only in the UserPassword.java file,and compile it again.
    Then it compile well.I goto the directory to get the .class files.
    But there is only UserPassword.class inside the data folder. There is not
    UserAccManager.class in the core folder.
    Then I try this way,I put my 2 java files in to a new folder,
    F:\SystemName\com
    When I try it that way, but it don't compile.
    javac -classpath . -d . com\*.javaError:com\UserPassword.java:package javax.servlet does not exist
    import javax.servlet.*;
    com\UserPassword.java:package javax.servlet.http does not exist
    import javax.servlet.http.*;
    So,I comment them only in the UserPassword.java file,and compile it again.
    Now both are compiling well.There was 2 class files.
    I put them in to the WEB-INF/classes/com directory.
    Start the server.But it gave errors:

  • Unable to compile class for JSP--- help me plz!!!!!

    hi friends;
    Pease suggest me where i am wrong, i think javabean is not instantiated in jsp file.may be it is related to the classpath of javabean. i have not set any variable for javabean classpath. and i put javabean class file in
    TOMCAT_HOME/webapps/test3/WEB-INF/UseDta.class
    and all the jsp and html in /test3. my jsp an javabeans are--
    1. GetName.html

    public void setAge( int value )
    age = value;
    public String getUsername() { return username; }
    public String getEmail() { return email; }

    **MAJOR SPAMMING SCUM BAG ALERT**
    I was puzzled in that you asked a SQL Server question in one post and then in another thread asked a Oracle related question... and then I noticed you had cross posted one of your questions at JavaRanch and I was more annoyed....
    and then I found this....
    http://saloon.javaranch.com/cgi-bin/ubb/ultimatebb.cgi?ubb=get_topic&f=10&t=002447
    You sir -> Michael Byrd -> are a scum sucking dirtbag.
    To quickly explain. Mr. Byrd posts his messages (which he copies wholesale from other posters) so that he can get better google caching for the website listed in his profile.
    This is such scummy behaviour I don't even know what to say. Other than basically everyone that has ever helped you had totally wasted their time.
    You are scum. Your company is scum. I hope you rot in hell.

  • Not Able  to Compile Java code

    Hi Java Gurus
    I am not able to compile this code Pl help
    class For {
    public static void main (String [] args) {
    int I = 0;
    show:
         if (I < 2) {
    System.out.print("I is " + I);
    I++;
    continue show;
    }

    class For {
    public static void main (String [] args) {
          for(int i = 0; i < 2; i++){
                  System.out.print("I is " + i);
    }this does the same as your program: the for loop is the best for this, but i agree with the others read some tutorials on loops in java. As posted before java has no concept of the GoTo syntax, loops or recursion are your only options

    ***************** END TOMCAT ERROR MESSAGE *********************

    Hi
    I am running my Tomcat apps (on a Windows dev machine) in an alternate location (ie. not default webapps). The same crap comes to me every time. Unable to install etc. I have tried every trick in the book regarding classpath settings etc.
    When I use 'javap' to check the classpath from any location on my machine, its works and javap returns the signature of my class.
    When I use it though Tomcat (with the import set to include the filename), it get the error. I have heard rumors that using JDK 1.3 in stead of 1.4 helps, but I just want it to work with 1.4 :)
    So if any of you can help me on this, please.
    PS. On my linux server it works just fine, as does every other thing on that machine ;)

    }I read in one blog (actually - the only page which was returned by yahoo - so - this should be very rare error!!!) to try to use Sun server's verifier.bat - and - it reported 0 errors and 0 warning. Build was succesfull as well and also - deployment was without errors - but - above mentioned error appeared during the automatic compilation of jsp pages/servlet when newly deployed jsps are first accessed from remote browser.
    So - is it possible, please, to receive some advice - what to do further? I feel that my invoice.jsp page can be with errors, - however - the original welcomeJSF.jsp should be working without errors even the erronwous JFS jsp page is added to web application.
    Thans for any adice or hint in advance!!!

    OK - I have made 'clean and build main project' from NB menu and the deployed the resulting *.war and the error messages have disappeared... So - it seems to be bug...

  • Error:Unable to compile class for JSP

    Hi all,
    I am new at jsp,just started to learn a week ago :) Anyway I'm having troubles with using a compiled java class in jsp code.I use tomcat 4.1.31 and java 1.4.2.I have compiled the following programm and put the class into tomcats' webapps\ch06\WEB-INF\classes directory
    public class ch06_01
    public ch06_01()
    public String msg()
    return "Hello from JSP!";
    Then I have the following jsp file in the webapps\ch06 dir as well:
    <%@ page import="ch06_01" %>
    <HTML>
    <HEAD>
    <TITLE>Using a JavaBean</TITLE>
    </HEAD>
    <BODY>
    <H1>Using a JavaBean</H1>
    <% ch06_01 messager = new ch06_01(); %>
    The message is: <%= messager.msg() %>
    </BODY>
    </HTML>
    But when I try to ran the jsp page following error occures:
    org.apache.jasper.JasperException: Unable to compile class for JSP
    An error occurred at line: -1 in the jsp file: null
    Generated servlet error:

    Can anybody help me,please!I appreciate your help a lot!
    Thank you verry much!
    Best regards Daisy

    Its not a Tomcat issue per se, but a change in the J2SE.
    Its been the case since the release of Java 1.4, when they disabled access to the "default" package. Quite a few of the books written before Java1.4 was released are still around, and there are endless examples around the net that no longer work as a result of this change.
