Returning CGI variables thru java
I am trying to check the cgi environment variables on my application server 10.1.2. I am unable to get any of the ssl variables at all. I can run /cgi-bin/printenv and see all the variables. However I am unable to get them out thru java. I dont know if I am missing something in the configuration of the server or not. I have it set up to run SSL and SSLVerifyClient so the clients have to provide a valid certificate. I need to grab the information off of that certificate to authorize their access. Any help would be much appreciated. Thanks!
We did figure it out. We needed to make the following changes in our 10.1.3 environment. It should be similar in the 10.1.2 environment.
ssl.conf or httpd.conf -
Set the following setting in a context (either VirtualServer, Location,
Directory, or File - others may work)
SSLOptions +StdEnvVars
mod_oc4j.conf -
Add the following lines to if IfModule context
Oc4jEnvVar SSL_CLIENT_S_DN
Oc4jEnvVar SSL_CLIENT_S_DN_CN

if my longMessage is smaller like one line then everything works fine, but as soon as my longMessage if greater than 254 it starts giving me -404. How do I work around or Is there any way to use host variable in Java?
All kind of help is appreciated. Any question then please email me at [email protected].
Thank you.This is what you got to do to insert a larger value.
//Assuming that message length is less than 254+ 254 characters.
//If larger then run the update loop that many times.
String longMessage = "Blah blah ... ";
String firstPart = "";
String secondPart = "";
int messageLength = longMessage.length();
if (messageLength > 254)
try
firstPart = longMessage.subString(0, 253);
secondPart = longMessage.subString(254, message);
catch (IndexOutOfBoundsException e)
//In the first insert set the first 254 characters
ps.setString(1, firstPart);
int result = ps.executeUpdate();
if (result != 0)
System.out.println("Insert sucessful ");
if (messageLength > 254)
//now update with the second part.
static String UPDATE_SECOND_PART = UPDATE my.table SET LONG_COL = LONG_COL || ? WHERE KEY_COL = ?;

Weird one.. i can't return a variable from the extended to the super class
Hey everyone, i hope i'm not annoying you guys :)
So today's problem is to return a variable (int) from a method of the extended class and print it ont the super class.
I'm just testing the super class , if it works fine.
So the extended class ( FileIO) just read the file txt and return the integer or string ( from the txt file)
I already did a main method to that class and tested it, it works fine.
So now the problem is to print the integer ( that the extended class gets from the txt. ) inside the Super class. I mean , is the same thing but now im testing the Super class , just have to do the same thing, a super class method calls the extended class method and receive the integer from the txt file.
i think the problem is when i create the instance of the FileIO object , maybe its constructor ...i don't know.
The name of the txt file is passed from the super class to the extended class, but i think the error is not from there.
this.aero_le = new BufferedReader(new FileReader(super.ficheiroleitura_aero())); // super calls ficheiroleitura_aero() and receive the name of the txt file ( e.g "temp.txt") so i think that is correct.
here's the code of the Super class public class Aeroporto {
private String filereader_voo = "temporary.txt";
private String filereader_aero = "temp.txt";
private String siglaAero = "";
public FileIO file;
public Aeroporto(){};
public Aeroporto(String filereader_voo, String filereader_aero) throws IOException{
this.filereader_voo = filereader_voo;
this.filereader_aero =filereader_aero;
file = new FileIO();
public String siglaAero() {
return siglaAero; }
public String filereader_aero(){
return filereader_aero;
public int nrLines() throws IOException{ // it was supose to retunr the number of lines ( integer) from the txt file .
return Integer.parseInt(file.lerLinhaN(1,1));
// main() {
Aeroporto a = new Aeroporto();
int v = a.nrLines();
System.out.print(v);
// ***********************************************************+
// Extended Class
public class FileIO extends Aeroporto{
private String ficheiroescrita;
private PrintWriter vooescreve, aeroescreve ;
private BufferedReader voo_le, aero_read;
public FileIO(){}
public FileIO(String filereader_voo, String filereader_aero, String ficheiroescrita) throws IOException {
super(filereader_voo, filereader_aero);
this.ficheiroescrita = ficheiroescrita;
//If file does not exists , create one.
try{
this.aero_read = new BufferedReader(new FileReader(super.filereader_aero()));
aero_read.close();
catch(IOException ex){
this.aeroescreve = new PrintWriter(new FileWriter(ficheiroescrita));
aeroescreve.close();
public String lerLinhaN(int line, int column) throws IOException{ // this method works fine , i already tested this class.
this.aero_read = new BufferedReader(new FileReader(super.filereader_aero()));
for(int i = 0; i != line-1; ++i) aero_read.readLine();
String linha = aero_read.readLine();
String [] words = linha.split(" ");
return words[column-1];
Maybe the error is that i use to test the Super class a default contructor on both classes... i don't know where the error is, i also did two small classes ( super and another that extends ) and get the string "Hello" from the super and print it inside the extended..and it works, that's why i think the error is when i call the extended class .. need help.
thanks.Ok,

if (wordNumber>0 && wordNumber<words.length) outputWord = words[wordNumber-1];
} catch(IOException ex){

return(outputWord);
}Design notes... FileIO is a generic helper class... there is nothing specific to Airports, flights, or any other "domain" specific stuff in it... so it's re-usable... you can keep it and reuse it on other projects, or even share it with your friends.
So... The airport class will just call the static methods on FileIO like this ....
int lineNumber=1;
int wordNumber=1;
String airportCode = FileIO.readWord(airportsFilename, lineNumber, wordNumber);
....How's that?

Report Script returns no data and "java.io.FileNotFoundException" error
When attempting to write to a new file (Eg: C:\TEST.txt), Report Script returns no data and "java.io.FileNotFoundException" error occurs.
This error occurs only in Essbase 9.3.1.3 release, however it works fine in release 9.3.1.0.
After running the report the script, it pops up the follwing message:
"java.io.FileNotFoundException: ..\temp\eas17109.tmp (The system cannot find the file specified): C:\TEST.txt"
When checked the TEST.txt, it was empty.Sorry folks, I just found out the reason. Its because there was no data in the combination what I was extracting.
but is this the right error message for that? It should have atleast create a blank file right? -
Apache mod_rewrite CGI Variables in ColdFusion
I have an environment that consists of Apache 2.2.8 and ColdFusion 8 running on Solaris 10.
I am attempting to pass a CGI variable to ColdFusion as part of an Apache Rewrite rule, however I am not able to do so.
The Rewrite rule set exists as follows:
RewriteCond %{SSL:SSL_PROTOCOL} ^TLSv1$
RewriteCond %{HTTP_REFERER} !^$ [NC]
RewriteRule ^.*$ %{HTTP_REFERER}?result=pass [L,R,E=HTTP_MYVAR:rw]
The rule set works with the exception of the availability of the CGI variable HTTP_MYVAR within the ColdFusion CGI scope.
I am testing for the existance of the variable within ColdFusion as follows:
<cfif (structkeyexists(cgi, 'CGI.HTTP_MYVAR'))>
CGI.HTTP_MYVAR exists as:<cfoutput>#CGI.HTTP_MYVAR#</cfoutput>
<cfelse>
CGI.HTTP_MYVAR does not exist.
</cfif>
Does anyone have experience creating variables in an Apache Rewrite rule set and evaluating them in ColdFusion?
Thanks in advance for any assistance.OK, as part of my work-avoidance for the day, I have replicated the work I did in NZ on my other laptop.
I put this in httpd.conf
Alias /junk C:/webroots/junk
<Directory "C:/webroots/junk">
Options Indexes FollowSymLinks
AllowOverride None
Order allow,deny
Allow from all
RewriteEngine on
RewriteBase /junk/
RewriteRule (.*) $1 [E=MYCUSTOMVARIABLE:mycustomvalue]
</Directory>
And my test code is this:
<cfoutput>
CGI.MYCUSTOMVARIABLE = [#CGI.MYCUSTOMVARIABLE#]<br />
</cfoutput>
I restart Apache, run the template, and I get this:
CGI.MYCUSTOMVARIABLE = [mycustomvalue]
How does this differ from what you're doing?

Problem while Calling a CGI pgm From Java with code sample
Hey guys,
I am calling a CGI program from java servlet, while calling cgi program I am passing encoded(Base64) content via post process,
My problem is the encoded data is not posted as expected, the encoded data is corrupting. But when I send encoded data in a text file, cgi program is perfectly decoding and working fine.
Here I am doing Base64 encoding as per requirement, I cannot avoid this encoding.
My doubt is about OutputStreamWriter constructor argument , In OutputStream Constructor I am passing one argument is OutputStream object and another argument is encoding type. I tried with ASCII, US-ASCII & UTF-8 .
My code is as follows, please help me to resolve this issue.
URL url = new URL("CGI server path");
URLConnection urlConnection = url.openConnection();
urlConnection.setDoOutput(true);
OutputStream os = urlConnection.getOutputStream();
BufferedOutputStream buffer = new BufferedOutputStream(os);
OutputStreamWriter writer = new
OutputStreamWriter(buffer, "US-ASCII");
writer.write(encodedPDF-Content);
writer.write("\r\n");
writer.flush();
writer.close();
here encodedPDF-Content is String and it's size is 9565 bytesWhenever you read something in java into string (with Reader implementation) it expects source to contain text in encoding you specified. It then decodes it and makes 16 bit unicode string from it. Whenever you store string using Writers it does reverse operation with specified encoding (may be different than this which you used to read source) and stores text as a sequence of bytes made of 16 bit unicode string. So, passing text back and forth between programs with the help of files or I/O you can make mistake at both reading and writing encoding. Check for it.
Now, when C programm or other application reads file it may take another assumptions about encoding or may even completly ignore it and read source as a binary file. Then, if you have a source text as a file and have to pass it to other application never do it using Reader/Writer. User raw InputStream/OutputStream instead what will preserve all information unchanged.
here encodedPDF-Content is String and it's size is 9565 byteHow id you get this info? String.length() gets you how many chars is in it, it will be half the number of bytes. If you see your input file beeing 9565 bytes long, see my above statements. -

Creating XML file in Project folder thru Java Program
hi,
i need one help. i need to create XML file in web://<Project Folder> in xmII thru Java Program. i created one java code and i am able to access XML file that is in c drive. i created jar file for this and placed as action block in Transaction and this working fine. but problem arises when i give file path in java code as web://<folder name>/file.xml which is in Web folder of project in xMII.
How to access the file that is inside web folder from java code.
regards
senthilHi Senthil,
you can address the files that inside the MII workbench are viewed as "web://..." like this:
http://<server>:<port>/XMII/CM/<Project>/<Folder>/<Filename>
The workbench helps you find the correct filename:
- open the WEB tab in the workbench
- right-click on the filename
- select "Copy Link" from the pop up
Now you have the correct link in your clipboard.You can use the "web://" only inside MII.

Unmarshalling return; nested exception is: java.lang.ClassNotFoundException
I think what I'm trying to achieve is probably very simple (or at least should be) but I've been trying for at least 5 hrs now:
I'm using RMI for a distributed app I'm building for my degree.
Up until today I got around the need for using a SecurityManager by including all shared classes (those I pass between client and server) in a class library .jar file referenced by both client and server projects.
This has worked fine, but now I've coded a method that returns an object of a class that I do NOT want to include in the shared library (because I don't want the client to be able to construct these objects); therefore, I've decided to try and get the dynamic class loading working.
I'm using netbeans and testing on a single computer.
Here's what I'm trying:
My main() method has the standard code I've seen: if (System.getSecurityManager() == null) System.setSecurityManager(new RMISecurityManager());
In the server project's Run properties, I'm specifying VM Options: -Djava.security.policy=c:\security.policy -Djava.rmi.server.codebase="file://C:/"
I've copied the ellusive class's .java file into C:\ to keep the URL simple, but I've also tried directing it to the netbean project's bin\ folder using '%20' for spaces, both with the same results - about a five second pause (so it's finding something I think) and then the error message from the client's output:
error unmarshalling return; nested exception is: java.lang.ClassNotFoundException: mypackage.myClass
My policy file's contents are:
grant {
permission java.security.AllPermission;
I've tried about 20 different ways of formatting the codebase argument's URL.. can anyone help?
David
p.s. my OS is Windows 7Thanks EJP,
Yes, after posting I guessed it might want the .class file instead, so I directed it their instead - still no joy, unfortunately!
I'm carrying out all testing on one computer, so (+if+ I could get it to work) a local codebase address would not be a problem.
Noted about the server-side security manager. I might want to use callbacks, but the server still won't need to download class files from the client, so I'll still try and set the codebase, but will try without loading a security manager on the server-side.
For the time being I've put the class in the shared library but have defined it within the same package as the server code. By doing this I've been able to set the class's accessibility back to default, but the client can still access it as Object (from the shared library).
This solution is good enough, but I still wonder why the client refuses to accept the class file from the C:\ codebase. -
Capture full URL with CF CGI variable
I need to capture an entire URL and send it in the body of an
email, using CFMAIL. I'm looking at my CGI variables using CFDUMP,
but can't seem to get the entire URL string, including the
http:// or https://. Help?That part of the URL is intended for the browser, and is not relevant to the server so is not transmitted with the request, so it never gets to the web server, let alone the CF server.
If you need that info, you're gonna need to send it some other way.

Using jsp variable in java code
Hey guys,
I need some help hope you guys can help me.
I've declared a variable "error" in a jsp. how do I access this variable in the java code whice resides in the same jsp page.
I know I can use java variable in jsp code using
<%= sVariable %>
where sVariable was declared in the java code. but how do I access a jsp variable in java code??
Thanks very much in advanceThanks for the reply.
This is what I want to do.
I've declared a variable "error" using <c:catch var="error">I want to check the value of this variable and suppose if it contains XYZ (error variable will have a long string so I just want to check if it contains a specific value) I want to do step1 and if the variable of error is not XYZ I want to do step 2
Problem is I dont know how to check if error contains the XYZ in jsp thats why I thought java code would help here.
Can you guys suggest a better way to solve my problem.

Please help How can i run Os commands thru Java programs
Hey,
I want to stop and restart the linux server thru java program.Is it possible to run the os commands thru java program.
I had it thru Runtime.getRuntime().exec("*.exe");
it only runs the exe files.How can run files other than exe files like .bat,com ans shell commands..Any body knows please help with the code..or mail to this address
[email protected]
thankyou,
regards,
j.mouliWhat about "start command.com /C execute.bat", or using the overload that takes a String[] as argument?
What if you use the the full path of execute.bat?
What error code do you get?
And what comes th linux, I'm not sure... you'll need a shell interpreter there too, me thinks. (never had to run anything with runtime.exec on linux). Check the man pages if csh, bash, ksh, or what ever shell you like.
