Getting Server screenshot ... Apache Tomcat

Hi, I am using this JSP code to get Sreenshot of the server from client browser.
It works perfectly when I start the Apache tomcat using "C:\Program Files\Apache Software Foundation\Apache Tomcat 6.0.16\bin\startup.bat"
The problem is dat it WONT work wen I start tomcat as a service!!!
I am using Apache tomcat 6.0 on Windows XP SP2
please note that it works with weblogic10.0 server in developer mode
<%@ page import="java.awt.*,java.awt.image.*,java.io.*,javax.imageio.*" %><%
Toolkit toolkit = Toolkit.getDefaultToolkit();
Dimension screenSize = toolkit.getScreenSize();
Rectangle screenRect = new Rectangle(screenSize);
Robot robot = new Robot();
BufferedImage image = robot.createScreenCapture(screenRect);
response.setContentType("image/png");
OutputStream os = response.getOutputStream();
ImageIO.write(image, "png", os);
os.close();
%>

When Tomcat gets run as a service, it is most probably running in the "Local System account"
When you run it from your desktop, it is in your current user account - and can take a screenshot of the Desktop which is present.
Something I guess you can try
Edit the properties of that Windows Service (right click the service in the services control panel and select "properties"
Select the "log on" tab.
Try the checkbox "Allow Service to interact with Desktop". I'm not exactly sure what that does, but its worth a try :-)
Try specifying an account for the service to log in as - maybe that will make a difference.
There is no guaruntee that this will work! I haven't done this myself, and just forwarding some ideas to try.
I am by no means an expert on Windows services, and I could be completely wrong, however it IS worth at try right?
Good luck,
evnafets

How to integrate Apache Web Server and Apache Tomcat 4.0 ?

<pre>
Hi All,
Can anyone give me a detailed description(or url that tells so) of how to install the Apache Web Server, Apache Tomcat Server4.0 and Integrate both of them.
Still now I am using Apache Tomcat 4.0 as a standalone application and now I want to learn how to install,use Apache Web Server and integrate this with Apache Tomcat.
Please point me to exact location,url to download the recent Apache Web Server and,
Can I use my existing Standalone Apache Tomcat 4.0 to integrate this with Apache Web Server that I am going to download.
A detailed explanation of how to integrate both is very helpful.
Thanks in advance.
<pre>

The way to integrate Apache Web Server & Apache is very easy. The first step is download the library to connect both servers. This library can be download from http://jakarta.apache.org/builds/jakarta-tomcat-4.0/release/v4.0/bin/webapp-module-1.0-tc40-windows.zip.
Copy the files to APACHE_HOME\modules and open httpd.conf to change any lines:
You find the section "LoadModule" and you add the next lines:
LoadModule webapp_module modules/mod_webapp.so
AddModule mod_webapp.c
And the end of the file you must add these lines:
WebAppConnection conexion warp localhost:8008
WebAppDeploy examples conexion /examples
The first parameter -2nd line- (examples) is the URL name application, the second is the connection's name and the last parameter is the application's name. This name is the same which in servlet.xml.
At last you can add one more lines to check the module's configuration:
WebAppInfo /webapp-info
If you visit http://<yoor_host>/webapp-info you can see the configuration.

Print Server with Apache Tomcat 6.0 and Cocoon 2 Problem...

Hi,
My company have 2 server, (9i - APEX_3.1.2.00.02) and (10g - APEX_3.1.0.00.32), both in Http server running in OEL 4.0.
I tried the following cocoon installation in other window server,
http://carlback.blogspot.com/2007/03/apex-cocoon-pdf-and-more.html
and I set both APEX Instants Setting, the report printing setting according to the installation above.
The 10g apex run perfectly, however the 9i apex cannot print pdf report. the following is the error message show when i click on the export pdf button.
The webpage at http://server9i:7777/pls/apex_camnet/f?p=105:1:3689040380318743457:PDF: might be temporarily down or it may have moved permanently to a new web address. Error 324 (net::ERR_EMPTY_RESPONSE): Unknown error.
Before i add the print server to (9i), the pdf can be export, however no content inside the pdf, some corrupted detected, but when I added the report printing setting, the message above shown.
Is this because of the version of database? or the version or APEX? or other matter i did not aware?
Pls Help.

Problem accessing exception object in jsp error page - Apache Tomcat 5.0.25

Hi all,
I'm thoroughly confused and need some help. I've deployed a very simple web application in Apache Tomcat 5.0.25 to test exception handling - errortest.jsp and error.jsp. errortest.jsp throws a divide by zero exception if executed with default values in text fields.
When I put the directive IsErrorPage="true" in error.jsp i get a HTTP 500 error when error.jsp is accessed. If I remove it error.jsp is displayed but I cant access the exception object - if I try to I get an exception below:
org.apache.jasper.JasperException: Unable to compile class for JSP
An error occurred at line: 5 in the jsp file: /error.jsp

          int second = Integer.parseInt( request.getParameter( "second" ) );
          int answer = first/second;
     %>

</html>
NB: I am able to catch and display the exception if I use a try/catch block around the division as shown below.
try {
int answer = first/second;
} catch( Exception e) {
e.printStackTrace( new PrintWriter(out) );

Securite apache/tomcat

Hi!
I have a application written in jsp/servlets. I has some static resourses that tomcat protects when running it as standalone. But when I deploy this web-app on a server with apache/tomcat apache serves those static files that I would like to be protected.
How can I tell apache to use tomcats security constraints and knowing when a user has logged in and not?
Thanks in advance
Roland Carlsson

I just read an article about securing tomcat that is riding behind apache. Free chapter from oreilly at:
http://www.oreilly.com/catalog/tomcat/chapter/ch06.pdf
the pdf does a decent job of showing how to REALLY secure tomcat. the above post also shows how to do it... apache doesn't know anything about tomcat's security, nor does it know about resources that the webapp spec say are protected by the container. SO, you have to explicitly tell apache not to serve from those directories. alternatively, not having apache have access to the tomcat install location is not a bad idea either, and you then ONLY hand *.jsp requests to tomcat through the connector. then, as long as your jsps aren't in WEB-INF (which is actually used as a security protection if you set things up right for heavy included systems), apache can't get to WEB-INF.
dukes?

Hi ..
It's the OS X, not just your browsers.
If your Mac is running v10.6.8 as your profile suggests, you will have problems opening websites.
You need to upgrade to a newer OS X. Apple no longer provides security updates for v10.6.8.

How to protect an application running on Apache Tomcat app server with OAM 11gR2

Gurus,
We have an Apache Tomcat based application named "ABCD" here at client site that we want OAM 11gR2 PS1 to integrate with for SSO purposes. I have successfully configured OHS to reverse proxy requests to Apache Tomcat server whenever somebody tries to access the application URL but still, I am getting the application login page once I have successfully authenticated on OAM SSO login page. The Tomcat based application is authenticating users against a "UserDatabase realm".
I know in terms of weblogic application, there is an OAM identity asserter provider which then populates the User Principal for the java environment with the authenticated OAM user. But there is no such OAM identity provider for Tomcat.
So my question is, is there an provider (or Tomcat equivalent) which will entrust authentication to a header, that could be used to populate the Java User Principal from the OAM_REMOTE_USER header? Is the weblogic equivalent of authentication providers present in tomcat as well? Are those called valves?
Please advise to the earliest.
Thanks !!

Aakash,
I did follow the 4 steps that you mentioned to me. Out of the 4 that you had mentioned, I already had the webgate in place on OHS server and I was already passing the remote_user http header in oam policy as action.
As part of Step #2: Install mod_jk plugin on OHS server that you mentioned
1.) I downloaded the tomcat connector - tomcat-connectors-1.2.37-src
2.) I had to run ./configure,make, make install on my OHS server which runs on RHEL 6. It created the mod_jk.so file. I pasted it in the needed folder.
3.) I then created the httpd.conf file and workers.properties file as said in the connector docs.
4.) Restarted OHS.
As part of Step #3: Configure tomcat's ajp connector that you mentioned and I went through all the links pasted below but didn't find actually what needs to be in place to configure tomcat's ajp connector. I do see in the server.xml of tomcat app server that the ajp 1.3 protocol is supported:
http://tomcat.apache.org/tomcat-4.0-doc/config/ajp.html
http://tomcat.apache.org/tomcat-3.3-doc/mod_jk-howto.html#s8
http://tomcat.apache.org/tomcat-7.0-doc/config/ajp.html
http://www.mulesoft.com/understanding-tomcat-connectors

    <Connector port="8080" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="8443" />

    <Connector port="8009" protocol="AJP/1.3" redirectPort="8443" />
Do we need to disable the HTTP protocol in Tomcat and keep only AJP connector enabled? If yes, how to do that?
I am trying to connect to the application from OHS server like so I am using the http protocal right? How should I use the ajp protocol to connect to tomcat application?

Thanks !!!!!

Edited by: sandy on Nov 9, 2010 8:59 AM

java.sql.SQLException: ORA-00904: "SANDY": invalid identifier
Looks like the sql you are submitting is invalid.
Print out a copy of the sql you are trying to run and you will probably get:
SELECT * FROM OURUSERS WHERE usr = Sandy and password = secretThat isn't valid sql. It is missing quotes around the values you are checking.
This is the corrected sql query:
SELECT * FROM OURUSERS WHERE usr = 'Sandy' and password = 'secret'so one solution would be:
String sql = "SELECT * FROM OURUSERS WHERE usr = '" + user + "' and password = '" + pwd + "' ";However that is not optimal. It exposes your code to sql injection attack.
The better way is to use a prepared statement:
String sql = "SELECT * FROM OURUSERS WHERE usr = ? and password =?";
st = con.prepareStatement(sql);
st.setString(1, user);
st.setString(2, password);
rs = st.executeQuery();cheers,

Problem connecting oracle database to jsp pages using Apache Tomcat server 8.0

Well...I tried too many things..googled so many times..but still could not find solution to my problem.
I use windows 8 Enterprise Edition(if this has to do something with the problem)
Oracle 11.2.0
Apache Tomcat server 8.0
JDK 1.7
My oracle is installed in the D: drive and tomcat in c:. i copied the ojdbc6.jar file from oracle to lib directory of tomcat server.
Then i set CLASSPATH in environment variables as "C:\Program Files\Apache Software Foundation\Tomcat 8.0\lib\ojdbc6.jar" in system variables
My path variable is set as "C:\Program Files\Java\jdk1.7.0_02\bin".
My program is as follows in notepad:
<%@ page import="java.sql.*" %>
<html>
<body>
<%
Connection conn;
Statement st;
ResultSet rs;
try{
new oracle.jdbc.driver.OracleDriver();
String dbURL="jdbc:odbc:oracle:thin:@localhost:1521:XE";
String userId="system";
String pwd="moon";
conn=DriverManager.getConnection(dbURL,userId,pwd);
st=conn.createStatement();
rs= st.executeQuery("SELECT * FROM login");
while(rs.next())
System.out.println(rs.getString(1)+""+rs.getString(2));
catch(Exception e){}
%>

>> ODBC Driver Manager ... Data source name not found
That appears to be ODBC drivers looking for a DSN (Data Set Name). If it wants a DSN, the DSN has to be specified in the code, and the DSN has to be configured in the windows host ODBC applet. So that is at least two squirrels to get in the right tree before moving forward. A ...host:...[port:]SID|service name are some of the bits needed in a jdbc connect string, and that is in no way related to DSNs. A Whole Different Animal. If it wants a DSN that might be what needs to go in the URL bit.
And ODBC setups can be confusing, especially if an x64 OS is in the mix- if that is the case there are two different ODBC configuration applets, one for x64 the other for x86, and if one gets as far as talking to an actual database it might toss an architecture error. Only way to fix that "problem" is *delete* the ODBC DSN and then run the correct (maybe the x86) ODBC config utility, and set up the DSN. Again.

Apache Tomcat/4.0.6 - HTTP Status 500 - Internal Server Error

Hi all,
I am using JBulider 8.0 and developing a web application in JSP and Access. When I run the application, i get the following error while going from an HTML page to a JSP page:

Problem in configuring Apache Tomcat Server

Hi, I am facing problem in configuring Apache Tomcat server. I have downloaded its version 4.1.18 from the Internet. After unzipping and installing it, I have enabled the Root Context, enabled the Invoker Servlet, haven't changed the port to 80 from default 8080, have turned on the Servlet Reloading, have set the Java_Home variable in autoexec.bat, and have changed the DOS memory setting to 4096.
Also, the concerned lines in my autoexec.bat file look like this:
path c:\windows;c:\windows\command;c:\jdk1.2;c:\jsdk2.0;
c:\JavaWebServer2.0;c:\jakarta-tomcat-4.1.18
set java_home=c:\jdk1.2
set tomcat_home-c:\jakarta-tomcat-4.1.18
set classpath=.;c:\ServDevel;.;c:\jakarta-tomcat-4.1.18\common\lib\servlet.jar;.;c:\jsdk2.0\lib\servlet.jar;.;
Still, after having done all this, when I start the server using startup.bat (which happens without any problems) and type in http://localhost:8080/ on the browser to test the server, nothing happens. It doesn't show me the Tomcat Welcome screen. I get an error page saying "This page is not available". Why? Where am I going wrong?
Sushant

1) Try http://127.0.0.1:8080
2) set tomcat_home-c:\jakarta-tomcat-4.1.18
Is the minus-sign after tomcat_home also in the autoexec.bat?
Replace it with an equals-sign
3) When you run startup.bat, is a new command window opened and are the following three lines displayed at the end? It should stay open, otherwise something is wrong (unless running as a service).
INFO: Initializing Coyote HTTP/1.1 on port 8080

Unable to resolve Apache-Tomcat after 5.0.2 Upgrade / Content Server Install

I recently upgraded from 5.0.1 to 5.0.2. With 5.0.1, I was able to resolve to http://<apache-tomcat.domain.com>:8080 as well as http://<apache-tomcat.domain.com>:8080/ptcsand http://<apache-tomcat.domain.com>:8080/ptcs/diagnosticsTest.jsp. However, after upgrading to 5.0.2, I am unable to resolve to any of these URLs. The 'Content Server' admin. folder shows up within the admin. ui and all necessary objects are there. Other than the upgrade, no other changes were made to the server. Any suggestions? Thanks.

Did you upgrade to Tomcat 4.1.27LE version ?
