Problems with JSP and Tag Libraries in JBoss using Tomcat 5.5.9

Hi,
I am experiencing a really weird situation here. When running a deployed EJB3 ear application in a JBoss 4.0.3sp1 application using Tomcat service 5.5.9, Jasper is unable to compile any JSP file using Tag Libraries. To be more precise, when generating the Java source file (looking in the 'work' directory) everything in the file after the first occurance of a Tag Library usage is commented out (with "//"), causing the Java source to be invalid and outputs an error when accessing the page via a browser saying:
"org.apache.jasper.JasperException: Unable to compile class for JSP
Generated servlet error:
Syntax error, insert "}" to complete ClassBody
Generated servlet error:
Syntax error, insert "}" to complete Block
Generated servlet error:
Syntax error, insert "finally" to complete TryStatement
Generated servlet error:
Syntax error, insert "}" to complete MethodBody"
etc... where every error row is a suggestion of steps to take to make the source file valid. (of course).
The Tag Library jar files are located in the web application WEB-INF/lib folder as they should be. The descriptive Tag Library Definition files (tld:s) are located in the WEB-INF folder and every JSP file references these tld files directly via this path (WEB-INF/).
Any hints are most appreciated!!
Cheers!

Cookie Problem With JSP and Tomcat

I have a tiny web application developed for my project thing.
I am facing a problem while maintaining sessions with Cookie. I use Tomcat 3.2.1 Web Server and JSP 1.2 Specifications for my web application.
I have created a page which creates a cookie and stores it in the client's PC, so when the same client visits the site, he can be remembered. Now while surfing the site in the same session, the site remembers the client. But once the client closes the browser and tries connecting to the site, he cannot be remembered. So I took a look into Temporary Internet Files of the client PC and found no cookie there. So where the cookie gets created and why does it disappears with the session. I have set a time limit of 1 year in the cookie.
Now is that a Problem with Tomcat or with the configuration settings of IE in the client PC?? Or something else???
Reply me Soon...

Thanks for your reply.
following is the code for how do i create a cookie...
<%
     String custno = custBean.createPreferred();
     Cookie c = new Cookie("pc", custno);
     c.setVersion(1);
     c.setPath("/");
     c.setComment("PreferredCustomer");
     c.setDomain("think_machine");
//think_machine is the name of the Web Server(Tomcat)
     c.setMaxAge(365*24*60*60);
     response.addCookie(c);
%>
And the code to read a cookie is..
     String custID = null;
     Cookie[] cookies = request.getCookies();
     for(int i = 0; i < cookies.length; i++)
          if(cookies.getName().equals("pc"))
               custID = cookies[i].getValue();
               break;
One more thing I would like to let you know, that i access this from the same PC on which the Web Server is installed. Means the Server and the client are both one and the same PC.

Initial problem with JSP Custom Tag devolopment

Hi ,
I have encountered a problem with my JSP application which utilizes a simple custom tag.
First I created followinng directories.
1. %TOMCAT_HOME%\webapps\testTags
2. %TOMCAT_HOME%\webapps\testTags\META-INF
3. %TOMCAT_HOME%\webapps\testTags\WEB-INF
4. %TOMCAT_HOME%\webapps\testTags\WEB-INF\tlds
5. %TOMCAT_HOME%\webapps\testTags\WEB-INF\classes
6. %TOMCAT_HOME%\webapps\testTags\WEB-INF\classes\com
7. %TOMCAT_HOME%\webapps\testTags\WEB-INF\classes\com\tek271
8. %TOMCAT_HOME%\webapps\testTags\WEB-INF\classes\com\tek271\testTags
I created the essential four files, that is named as follows.
1.TagError.java
2.web.xml
3.testTld.tld
4.testJsp.jsp
Then i put the files under these directories as given below
testJsp.jsp under %TOMCAT_HOME%\webapps\testTags.
web.xml under %TOMCAT_HOME%\webapps\testTags\WEB-INF
TagError.java under %TOMCAT_HOME%\webapps\testTags\WEB-INF\classes
TagError.class under %TOMCAT_HOME%\webapps\testTags\WEB-INF\classes\com\tek271\testTags
testTld.tld %TOMCAT_HOME%\webapps\testTags\WEB-INF\tlds
Here is the content inside the files.
1.TagError.java
package com.tek271.testTags;
import java.io.*;
import javax.servlet.jsp.*;
import javax.servlet.jsp.tagext.*;
public class TagError extends TagSupport {
private String mColor = "red";

} // setColor
public int doStartTag() throws JspException {
try {
JspWriter out = pageContext.getOut();
out.print("<font color=\"");
out.print(mColor);
out.print("\"><b>Error: ");
} catch (IOException ex) {
throw new JspTagException(ex.getMessage());
return EVAL_BODY_INCLUDE; // other return: SKIP_BODY
} // doStartTag()
public int doEndTag() throws JspException {
try {
JspWriter out = pageContext.getOut();
out.println("</b></font><br>");
} catch (IOException ex) {
throw new JspTagException(ex.getMessage());
return EVAL_PAGE; // other return: SKIP_PAGE

Dear patreck ,
It does not work.
I have replaced the line

with
<%@ taglib uri="WEB-INF/tlds/testTaglib" prefix="test" %>
but now it shows the error ,

Problems with JSP and MySql bean.

Hi,
I'm new to JSP and I'm having some problems with it. I'm trying to do a simple login where a java class (bean?) handles the SQL injektion. I have deployed the page on tomcat and it works fine, except that the sqlinjektion does basically nothing. I have installed the mysql driver. I think there is something wrong with the java class, or the way im calling it. It does not produce any error. But its like it would never actually process the java code, because ive tried to append things to error string to see what is going on, nothing happens. everything stay null, no exceptions are thrown. If I implement the code to JSP itself, it does load the driver and print exception that there is no connection to database (which is correct). What am I missing? Code follows:
the sqlhandler:
public abstract class SqlInjektor {
     private static String Database = "*****";
     private static String serverName = "localhost:3306";
     private static String usrName="******";
     private static String passw="******";
     * @return Connection
     public static Connection createConnection(String error){
          Connection mySqlCon = null;
          try{
               Class.forName("com.mysql.jdbc.Driver").newInstance();
          catch(Exception E){
               PrintWriter out = response.getWriter();
               out.println("lol");
          String url = "jdbc:mysql://" + serverName + "/" + Database + "?user=" + usrName + "&password=" + passw;
          try{

but i already set up the java compiler though i m getting this error. please help me.

You say you have set up the environment variables, but it is not working. You may have them set to the wrong thing. One common mistake is to point JAVA_HOME at the java/bin directory rather than just the /java directory.
Another set of eyes finds small mistakes in the variables that you might not spot yourself.
So please, post:
The values of these environment variables
The path to where the products are installed on your system (ie is it c:\java or c:\j2se1_4_2 or c:\program files?
I would take another close look at that JAVA_HOME variable to make sure of it :-)
Good luck,

Problems with XsltListViewWebPart and Migrated Libraries

I have migrated some libraries and lists from SharePoint 2007 directly to SharePoint 2013 (using some creative scripting). While this mostly works, I have a few stubborn libraries that refuse to work properly. The problem seems to be focused around the XsltListViewWebPart,
the default viewer of content since SharePoint 2010. The migrated libraries are imported with the functional ListViewWebPart, but if I make any changes to the view it's "upgraded" to the XsltListViewWebPart or if I create a new view it
uses the XsltListViewWebPart. While I would like to use the XsltListViewWebPart for its superior functionality, I receive the following error whenever a page with the XsltListViewWebPart for the library loads. Seems like it's missing the proper content
types possibly, but I can't figure out how to get around it.

Hi Jason ,
For troubleshooting your issue, please take steps as blow:
1.Remove Group By first on view and retest
2.Increase your resource throttling for the Web Application and retest
3.Recreate the broken view

Problems with jsp and jdbc

I am writing a simple class to start learning about jdbc. I wrote the following WHICH COMPILES:
public MyClass {
System.out.println("establishing connection...");
OracleConnectionPoolDataSource ods = new OracleConnectionPoolDataSource();
// this is where all the variables are initialised.
ods.setDriverType ("oci8");
ods.setServerName ("test");
ods.setNetworkProtocol ("tcp");
ods.setDatabaseName ("tester");
ods.setPortNumber (1521);
ods.setUser ("test");
ods.setPassword ("password");
// this is the variable that will get the connection pool.
// from this connection pool, you will get all ur connections.
pool = new OracleConnectionCacheImpl(ods);
and i am calling it by:
System.out.println("connecting to DataBase");
dbc = new MyClass();
System.out.println("connected to DataBase");
THIS WORKS FINE when i do either a command line execution - run a query thru a normal main method.
HOWEVER, when i try and call it from a jsp page, i get the following error from tomcat:
org.apache.jasper.JasperException: oracle/jdbc/pool/OracleDataSource
at org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:248)
furthermore, the first system.out.println("establishing connection"); is not printed. "Connecting to Database" is printed however. i am really confused.
however, i have an ancient copy of tomcat 3.2 that i used - just to test - and that worked fine. i have to get this to work with tomcat 4.1.
i am really in a jam - any insights, please help!!!
thankyou so much.

Mahesh,
It is the problem of your DRIVER not being in the classpath of TOMCAT. Put the driver in the lib folder of tomcat or else include the folder which contains the driver to the tomcat classpath. It should work OK.
Good Luck.

I have transfered the web.xml file and lib and classes folder in a WEB-INF folder and also all the JSP files. I can see he JSP file, but the 'hello worl' does not work and gives this exception!
Does any one have any idea what could be the problem?
thanks a lot
Mitra

seems the web Server code previously loaded a class only when it was used rather than when it was referenced,
ask your question in the tomcat-user mailing ! !!!

Anybody have problems with midi and XP? (especially anybody using a GI-20)

Hi
I'm trying to use my midi device (a Roland GI-20) with boot camp/XP but with no success.
I have downloaded XP drivers from Roland but XP won't let me install them, saying they are no better than the default drivers already installed.
It appears as a device (but XP renames it as a USB sound device and not GI-20) but when I select it in a DAW for example and generate midi nothing gets through.
ANybody else had similar problems?

Korg Legacy and the XV are not critical to my workflow, just items I had invested on I would like to keep. I did not research compatibility with Snow Leopard vwery thoroughly for those two, but I certainly did with the interface, which IS critical. Focusrite has released brand-new drivers that are supposed to be compatible with Snow Leopard, as they loudly trumpet on their web site.
And by and large, they do work - there's just that incessant noise. And THAT's an issue, and somehow I doubt it has to do with the interface as, like I mentioned, the noise only appears during the bootup sequence when, I assume, the Firewire drivers are loaded.
Inputs?

[SOLVED] Problem with netctl and dhcpcd

Hi everybody,
I had a problem with netctl and dhcpcd.
I was using netctl and wifi-menu to connect to wirelless networks with dhcp.
It worked fine at home, then i went to a friend where it also worked but then i went back home and it failed at every try with those error messages:
dhcpcd[2718]: version 6.0.5 starting
dhcpcd[2718]: wlp9s0: rebinding lease of 192.168.1.154
dhcpcd[2718]: wlp9s0: reject NAK via 192.168.178.1
dhcpcd[2718]: wlp9s0: soliciting a DHCP lease
dhcpcd[2718]: wlp9s0: offered 192.168.178.44 from 192.168.178.1
dhcpcd[2718]: timed out
network[2659]: DHCP IP lease attempt failed on interface 'wlp9s0'
systemd[1]: netctl@wlp9s0\xxx.service: main process exited, code=exited, status=1/FAILURE
systemd[1]: Failed to start Automatically generated profile by wifi-menu.
systemd[1]: Unit [email protected] entered failed state.
I figured that dhcpcd tried to rebind an ip that my router rejected and didn't accept the ip that it offered instead.
The solution was to delete:
/var/lib/dhcpcd/dhcpcd-wlp9s0.lease
now how can i configure netctl and or dhcpcd so that won't happen again and that it accepts all ips offered by routers?
Last edited by Samy (2013-09-04 13:32:13)

I've had this happen now and again. You can rebind the lease yourself with:
$ dhcpcd --rebind
You could also try increasing the timeout by adding
TimeoutDHCP=
to your netctl profile/s - see netctl.profile(5) as WonderWoofy suggests. Although I haven't tried the latter.

Java Beans and Tag Libraries and JSP

Is it ok to write all the Javacode into a JSP page?
If not,
is plain JavaBeans okay or is Tag libraries better.
Basically I am creating a simple webpage for users to enter info into a database and retrieve information as well.

Is it ok to write all the Javacode into a JSP page?That's generally considered bad design. It's a good idea to separate the display (JSP) from the rest of the business logic.
If not, is plain JavaBeans okay or is Tag libraries better.Tag libraries are often used as a good way to separate display and logic.

I'd recommend using JSP for simply displaying the HTML forms or the results of the information retrieval, servlets to receive and handle the HTTP requests, and plain old Java objects (POJOS) as helper classes to do all the data transfer. There are several web frameworks available that can help you out in this regard (Struts, etc.), but there is a learning curve involved and they may be overkill for a (very) small website.
Hope this helps... :o)

Problems with JSF and included subviews

Hi everybody,
I' ve got a problem with JSF and included subviews which makes me going
crazy. I've got no clue why my web-pages are represent wrongly. The only
tip I've got is that it must be connected with the kind I do include my JSF-pages.
When I use <%@file="sub.jsp"%> my pages are are represent right. When I use <jsp:include page="Sub.jsp" /> or <c:import url="Sub.jsp" /> ( mark: the usage of flush="true" or flush="false" doesn't matter )
my pages are represent wrongly.
The usage of tags like f:facet or f:verbatim were also included but didn't point to an solution.
I searched the whole Sun Developer Forum and some other web-sites for any solution for my problem but the given hints and clues didn't help. Now I'm trying to post my problem directly in Sun's Forum in hope to get help.
My environment is the following:
JAVA JDK 1.5 Update 4
Tomcat 5.5.9
JSLT 1.1
Sun JSF 1.1
Win 2K
Here's my code:
Main.jsp
<%@ page language="java"%>
<%@ taglib uri="http://java.sun.com/jsf/html" prefix="h"%>
<%@ taglib uri="http://java.sun.com/jsf/core" prefix="f"%>

Hello Zhong Li,
many thanks for your post, but it didn't work.
My problem is that the JSF-Components im my included or imported
JSP-Pages does not accept any kind of style or styleClass for
designing. The components take over the informations for colors
but not for alignment.
When I take a look at the generated JAVA-Source in $TOMCAT/WORK/WEBAPP for my sub.jsp ( sub.java )
it seems that the resulting HTML-page would be presented correctly.
But later when I start the application via Firefox or Mozilla the html-sourcecode is totally wrong.
In my example I create a simple grid with 2 rows and 2 columns.
Both columns contains JSF-Outtext-Components and are included with div-tags.
The generated Sub.java shows that the text would be setted in the div-tags. Unfortunately the html-sourcecode represented by my browser shows that jsf-text is not setted in the tags but in the <h:form> tags. The div-tags are neither rounded by <h:form> nor containing the JSF-OutText-Components.
Any clue?
Many thanks Benjamin
