Problem in passing vector from an applet to servlet
Hi,
I m facing problem in reading an object in the servlet (that i send from an applet). I have used BufferedInputStream ... The servlet reads the object but it takes about 30 seconds to do this ... If i don't use BufferedInputStream, it gives an "error reading inputstream header" ... if i use it, it take 30 seconds ... i m using netscape ent. server 4.0 ...
Servlet code is as follows :
try {
InputStream in = req.getInputStream();
inputFromApplet = new ObjectInputStream(new BufferedInputStream(in));
saveVector = (Vector)inputFromApplet.readObject();
I don't understand why it takes so long ... is there any other way ? Please help on this ... you may email me on [email protected]
Thanks in advance..
When you send a Vector through a stream, it must not only pass the Vector itself, but all the objects that the Vector refers to, all the objects that those objects refer to, and so on. Combine all this data with a slow internet connection, and passing what may seem like a small Vector could take minutes or hours.
Are you sure you're passing a very small amount of data over a fast connection?

Problem in passing data from 1 screen to another using BBP_DOC_CHANGE_BADI.
Hi Experts,
i am new to the SRM, i am facing problem in passing data from one screen to another.
my requirement is that when we select one shopping cart and press the PROPOSE SOURCES OF SUPPLY button, we will fetch all the contracts that are attached to the shopping cart.
we have implemented a BADI implementation of BBP_SOS_BADI (method BBP_SOS_CHECK) for passing some changed values to the contracts of the shopping cart into the popup screen that is displayed when we press PROPOSE SOURCES OF SUPPLY button and when we select any contract and press ASSIGN ONLY button in the popup screen the badi BBP_DOC_CHANGE_BADI is triggered.
i have implemented another BADI implementation of BBP_DOC_CHANGE_BADI for fetching the selected contract and pass the values to another screen, but the problem is that when we select one contract and press the assign only button we are fetching the wrong contract number ( that is in the BADI method BB_SC_CHANGE parameter IT_ITEM we are fetching the wrong contract), if we again do the same procedure for the second time we are getting the correct contract.
i am unable to understand why we are getting the wrong contract in the first time( that is we are getting contract other than the selected one).
as per my understanding i think when we are passing data to the popup screen using BBP_DOC_CHANGE_BADI we are not updating the shopping cart with the changed data.
can anyone tell me how we can update the SHOPPING CART with the changed contracts data, i have used BBP_PD_SC_UPDATE, BBP_PD_SC_SAVE and other shopping cart FM but nothing is happening.
Thanks
TanveerHello,
What version of SRM are you on? Have you check for OSS Notes? I have had trouble with BBP_DOC_CHANGE_BADI but it was because of other issues. The BADI works pretty well and it is called almost every time something happens to the shopping cart.
I have noticed that sometimes that values are not changed til the second calling of the BADI. I have yet understand why but I think it has to do with prompt processing. Usually, we train our requisitioners to click the 'Check' button to flush things out.
I don't know if I was helpful.... another thought.... could there be an error caught by BBP_DOC_CHECK_BADI that is preventing change in BBP_DOC_CHANGE_BADI?

Passing parameters from an applet to a URL
I need to pass information from an applet to an html page or JSP page, is this possible? Thanks.
Yes you can!
The following code might works (with some modifications ;)):
AppletContext context = this.getAppletContext();
URL url = new URL("http://host:port/path?parameter=value");
context.showDocument(url, "windowName");In addiction, consider java.net.URLEncoder.encode() method to encode properly your parameters.

Facing Problem with passing Values from One report to another
Hi,
I am Hemanth, I have developed 2 reports. Firast Report High Level Summary, Secong is detailed. First report is developed using Union(4 union) , I am having 4 columns. The report is generating the data. I have used Navigation option on Client Column to move on to Second report. In Second report with in Filter i am using Prompted option. Due to some problem, the client value from first report is not passing to the second one. The second report is getting generated for all the clients.
Normally i have used this Navigate option in other reports and that works fine. I have even tested with Union, it works. This time it is giving some trouble.
Please, let me know whats going wrong.
Thanks for the help.sorry for the late updation.
My First Report, Summary level is a Pivot Table.
I tried the same report with Table option, the value is passing correctly.
Is there a way to get rid of this situation using Pivot table.

Problem in passing data from one .jsp page to another .jsp page
i have a problem here
Actually i have 2 jsp pages. What im trying to do here is actually i want to pass data from the first jsp page to the second for updating
The first jsp page contains data that user wants to update in the form of table.
<td><img src = "edit.gif" alt = "edit" border="0" ><td>
<TD><%= Name %></td>
<TD><%= rs.getInt("Age") %></td>
<TD><%= rs.getString("Gender") %></td>
So this page displays the data that users wants to update plus one image button (edit button). So when user clicks this button, all the data in this page will be brought to the second .jsp page called updatePersonal for updating.
The problem here is that it is not displaying the existing data in the second .jsp page.
The second page basically contains forms
<INPUT TYPE="text" NAME="FirstName" maxlength="30" value = "<%=FirstName%>">
Can someone please help me. I really dont know what to do..How do i get the data displayed in the text field that is passed from the first .jsp page..thankx in advancePlease modify below code to:
td><img src = "edit.gif" alt = "edit" border="0" ><td>
-----------------modified code
td><a href="updatePersonal.jsp?FirstName=<%=rs.getString(FirstName")%">&LastName=<%=rs.getString("LastName")%>&Age=<%=rs.getInt("Age")%>&Gender=<%=rs.getString("Gender")%>"><img src = "edit.gif" alt = "edit" border="0" ></a><td>
I'm sure it works</a> -

Crystal Report - problem with passing parameters from J2EE app
i'm trying to pass a few parameters from my java application to a crystal report using the code below:
ParameterField pfield1 = new ParameterField();
ParameterField pfield2 = new ParameterField();
Values vals1 = new Values();
Values vals2 = new Values();
ParameterFieldDiscreteValue pfieldDV1 = new ParameterFieldDiscreteValue();
ParameterFieldDiscreteValue pfieldDV2 = new ParameterFieldDiscreteValue();
pfieldDV1.setValue("1056");//dform.getSelectedPeriod());
pfieldDV1.setDescription("termId");
vals1.add(pfieldDV1);
pfield1.setReportName("");
pfield1.setName("@p_termId");
pfield1.setCurrentValues(vals1);
fields.add(pfield1);
// check here for null condition otherwise will throw nullpointerexception
pfieldDV2.setValue("elect");
pfieldDV2.setDescription("allocType");
vals2.add(pfieldDV2);
pfield2.setReportName("");
pfield2.setName("@p_allocType");
pfield2.setCurrentValues(vals2);
fields.add(pfield2);
this report calls a stored procedure (sql server). the report displays the data but the same is not the case when i call ity from my java application. with a single parameter it works fine (even though i get a "Some parameters are missing values" ERROR on the console. But when i pass, say 2 parameters, it give me the above error first and then "JDBC Error: Parameter 2 not set or registered for output"
Can anyone bail me out of this one?
thanks,
ptalkadI don't know about naming conventions, but could the @ signs in the variable names cause a problem?
How have you set up the mapping in Crystal?
Is this parameter 2 an "out" parameter returning a value?

Problem in passing values from AS to Java
Hi,
I am using Remote Object(Flex 3) for passing the data

KranthiHi there. That's a perfectly reasonable question.
Take a look at the section of the Flex documentation with the title "Explicitly mapping ActionScript and Java objects" in the Data Access section of the doc.
http://livedocs.adobe.com/flex/3/html/help.html?content=data_access_4.html
Your BananaVO ActionScript class needs a RemoteClass metadata tag that will tell the AMF deserialization code on the server what Java class to map the object to.
Hope that helps.

Problem with passing parameters from HTML
Im unsure as to where to turn next with this problem. What is making it all the more infuriating is that I have had this code working previously and now cant for the life of me figure out how I did it.
What Im trying to do is I have a HTML page with two buttons on, one called "Submit Application" and the other "Submit Resource" and when I click on one I want a JSP page to be called and a certain piece of SQL to be executed, likewise when I click on the other "Submit Application" button I want a separate bit of SQL to be executed. (I know in this example both bits of SQL are identical but that is just while I get the functionality correct).
Whats happening is that the first bit of SQL will execute if I click the "Submit Resource" button, however when I click the "Submit Application"
button I get a "Error 500:" displayed. Im at the end of my tether as to what to do next and as I say it makes it all the more infuriating in that I had it working before. So any help would be greatly appriciated.
The code is as follows, I have highlighted the two IF statements :-

if (!Subapp.equals (null))
Well, what happens if Subapp IS equal to null. The .equals method call will be called from a NULL and you will get a NullPointerException.
When testing for null you do:
if (Subapp == null) (or if (Subapp != null)
This is okay when dealing objects even with the mantra of 'don't use == to compare objects, because what you are really testing is if the reference points anywhere, and == will compare the reference.
Also, next time you post, make sure to use the [code] tags as described in the [Formatting Help] link. It will make it easier to read.
Also, you should try to remove the SQL from the JSP. Move it into a Servlet which builds a List that forwards to another JSP for display, or use a bean. Using java classes like Servlets and JavaBeans makes it easier to debug, and makes your JSP code easier to manage. -

Till here we are able to put the Parmeter in Tranasction
After calling the custom page from standard page while we are using the Transaction value it is returning null.

Problem in passing HTML form values to a servlet in NetBean IDE
hi there,
When i click the submit button of the HTML File(with two textFields with values) the value received in the corresponding servlet is null , I used the get method to pass value so i was able to see the values in the URL but when i print the value in the Servlet it display null. I have verfied the web.xml to cheak the servlet mapping is right .Servlet mapping are perfect but i am not getting the value in the next page. Kindly give your suggestions.
Thanks in advaceTry this in your servlet.
HttpSession session = request.getSession(true);
System.out.println(request.getParameter("xxxxx").toString());
xxxx is the parameter name..
Doesn't this work? -
Passing Variables from JSP to a servlet
Presently I have a small Web application where by users enter data onto a jsp Page , this data then gets passed onto a servlet which then updates a sql database through a call to a sql stored procedure

any thoughts on the cause......below is the code to the servlet

Help with passing parameters from a servlet to an applet
dear all
i m working on a application which will check weather a file is present in a server (webserver) if it is present then it will take the file name and put it into a drop down list and there is a button on click of which i m taking the call to an applet and then on that i need the file name if it is there then i use it to draw a graph
i m struck on how to take parameter from Servlet -> Applet
thanks
Nakulhi,
I understood your question,The context "servlet" cannot communicate to
an applet becoz applet runs at clients browswer, rather you can communicate from an applet to servlet(HTTPURLCONNECTION class).
Well coming to the problem, this is how i have understood your problem,
basically uou get the list of files from the server using normal servelt programing and you will display in an html LIst box and then click the button to view the graph or chart ,
then you just want to pass the filename which is there in the listbox to an applet and applet will display some image.
As we know all that using <PARAM NAME=XX VALUE=YY> WE CAN GET THE VALUE IN APPLET BY USING GETPARAMTER() METHOD. and Im very sure that you are not asking that question. your question is like " both the applets and
the listboxes will be loaded at once and when he selects one of the file from the list box then without refreshing the page , how to display the graph.
Im i right?
If so i guess you have to use javascript to do that stuff, and i think its like gave an id for the tag shown <applet id="yes">
then in the javascript , you can call the Java applet methods (I have never tried before but seen some demos(i dont have that links- google it for inf))
but i can give clue like.. trying the <PARAM VALUE=""> IF POSSIBLE
CHAING THE HTML CONTENT IS POSSIBLE IN IE which is again through javascript by calling yes.innerHTML="<PARAM><PARAM><PARAM><PARAM>..."
Im sure that you can call Java methods from javascript but i never tried and even you can pass an arguments to it.. Let me check out like
becoz even im interested to know abt it
bye

Passing input parameters from an applet to a JSP page
Hello all,
Yes, its one of these questions which I have tried to find a solution from the already large number of postings but with no luck. I'm still a novice to Java/JSP so bear with me.
Consider this scenario.
1. An applet which has two input boxes (say First name and surname). 2. These parameters will be passed to a JSP page (so the applet will call a JSP page).
3. The JSP will have have the necessary logic (or actually a JavaBean will) to connect to a database and add a new record with these parameters (first name and surname).
I also need to consider editing/updating the record in the database. So a JSP page will connect to the database, retrieving the required record from the database and then display the parameters back in an applet in two input boxes (first name and surname) to be edited and saved again.
I have been able to develop a similar application using simple HTML forms to add and update records in a database so I'm not worried about the database connectivity simply the issue of passing parameters from the applet to the JSP page and vice versa (for edit/update).
Once i've managed to do this with input boxes, I can experiment with the other input types radios, checkboxes, select etc.
Many thanks in advance,
Assadcreate an URL object with u'r specified link of the java class and send the parameters..write trhis action in any buttonclick event in u'r applet.
