i read question earlier week. @ time, didn't have answer you. stumbled on methods setstartpage() , setendpage() on pdfbox documentation pdftextstripper class , made me think of question , answer. it's been 4 months since asked question, maybe someone. know learned thing or 2 while writing it.

when search pdf file, can search range of pages. functions setstartpage() , setendpage() set range of pages searching. if set start , end page same page number, know page search term found on.

in code below, using windows forms application can adapt code fit application.

using system; using system.windows.forms; using org.apache.pdfbox.pdmodel; using org.apache.pdfbox.util; //the diagnostics namespace needed specify pdf open parameters. more on them later. using system.diagnostics; //specify string searching string searchterm = "golden"; //i using static file path string pdffilepath = @"f:\myfile.pdf"; //load document pddocument document = pddocument.load(pdffilepath); //get number of pages int numberofpages = document.getnumberofpages(); //create instance of text stripper text pdf document pdftextstripper stripper = new pdftextstripper(); //loop through pages. search page page (int pagenumber = 1; pagenumber <= numberofpages; pagenumber++) {     //set start page     stripper.setstartpage(pagenumber);     //set end page     stripper.setendpage(pagenumber);     //get text page range set above.     //in case searching 1 page.     //i used tolower method make text lowercase     string pdftext = stripper.gettext(document).tolower();     //just fun, display text on each page in messagebox. pdf file has 2 pages. might annoying if have more.     messagebox.show(pdftext);     //search pdftext search term     if (pdftext.contains(searchterm))     {         //just fun, display page number on found search term         messagebox.show("found search term on page " + pagenumber);         //create process. opening pdf document specific page number         process myprocess = new process();         //i specified adobe acrobat program open         myprocess.startinfo.filename = "acrobat.exe";         //see link below info on pdf document open parameters         myprocess.startinfo.arguments = "/a \"page=" + pagenumber + "=openactions\"" + pdffilepath;         //start process         myprocess.start();         //break out of loop. found our search term , opened pdf file         break;     } } //close document opened. document.close();

java - IntelliJ - No such instance method -

using intellij's 12 ultimate, i'm running following code in debugger: java import play.api.libs.json.jsvalue; public class foo { ... public jsvalue tojson() { ... } public class fooexample { ... foo foo = new foo(); system.out.println("...); //<-- breakpoint at breakpoint, right-clicked source code , picked "evaluate expression," typing in: foo.tojson() . but following error showed up: no such instance method: play.api.libs.json.jsvalue$class.com.foo.foo.tojson () am doing wrong? foo#tojson calls scala code, if matters. edit had breakpoint after instantiation of foo. downvoted it, deserved it. edit my answer no longer valid after op modified question (i.e. moved breakpoint actual is).. a breakpoint hit before line executed. in case foo has not yet been declared or instantiated (i.e. foo constructor has not yet been called). you'll need put breakpoint @ next line (or step on current line) if want evaluate foo .

[dom] the value must unique amongst ids in element's home subtree , must contain @ least 1 character. the value must not contain space characters. note: there no other restrictions on form id can take; in particular, ids can consist of digits, start digit, start underscore, consist of punctuation , etc. note: element's unique identifier can used variety of purposes, notably way link specific parts of document usin
