This article mainly explains "what are the common questions about JBuilder". Interested friends may wish to take a look. The method introduced in this paper is simple, fast and practical. Let's let the editor take you to learn what are the common problems in JBuilder.

. how to use JB3.5 under WIN2000

When JBuilder3.5 is used under WIN2000, the Chinese characters on the IDE interface will not be displayed. The reason is that the JDK carried by Jbuilder3.5 is 1.2.2, and the setting of Chinese character library under WIN2000 is not supported by default. The solution is to rename font.properties.zh.NT4.0 under Jbuilder35/jdk1.2.2/jre/lib to font.properites.zh or font.properties.zh.NT5.0

2. Improve the running speed of JB3.5

JDK1.3 has a HotSpot feature, which is said to dramatically improve the running speed of Java programs, and this feature is ported to JDK1.2.2. Considering that Jbuilder is written in Java, why not port HotSpot to JB3.5 's JDK. Do this: just copy the jdk1.3/jre/bin/hotspot directory to Jbuilder/jdk1.2.2/jre/bin. However, because using HotSpot with Debug loses speed, you need to add additional run and debug parameters to limit the use of HotSpot when debugging. Just add-classic to the project property/run/vm parmeter box.

3. Cursor positioning of JBuilder4 editing window

When using JBuilder4, some users will find that the cursor cannot be positioned correctly when editing the program. This is because Editor uses the wrong font. Right-click in the blank space in the Editor, select Editor Options, (you can also bring up the Editor Options dialog box in other ways), select the Display page, and set the font to DialogInput.plain or Lucida Console.

There are two points for netizens to understand: first, there is too little personal free time to guarantee timely answers. Second, personal experience is limited, the answer is for reference only.

4. Chinese problems in the application of applet and CORBA

Problem: encounter a thorny problem. Under JBUILDER3,PWIN98, use applet to connect with the database through CORBA. Both the applet and the server can process Chinese normally, but the Chinese transmitted by applet to the server is garbled.

Answer: I don't know if you are using wstring as the data type for transmission. In addition, you should pay attention to using the same Locale on both sides of the server / client.

5. CORBA program distribution

Question: I am now using jbuild+visibroke to develop CORBA system. Here I would like to ask you how to develop a program that is separate from jbuild as a separate product. The product requires that software support (preferably with a reference price for supporting software). In addition, please explain how to start the "server application" of this product (a corba product developed by yourself). We are eagerly waiting for your help.

Answer: this is a distribution question of the CORBA program. Use VisiBroker for Java to develop CORBA applications in the final run in addition to your program should also include the following parts of the 1/Java virtual machine, for running Java procedures: -) 2/VisiBroker ORB, to put it simply is the vbjorb.jar file 3 / your program used in the Service, such as Location Service Smart Agent 4 / loader, you can use batches such as Windows platform vbj-VBJclasspath yourPackageName.jar fullMainClassName or java-cp vbjorb.jar;yourPackageName.jar fullMainClassName. Need to purchase VisiBroker distribution license: -)

6. BAS configuration in JBuilder

Problem: after configuring BAS in JBuilder, JBuilder will never start again. What could be the problem?

Answer: if nothing else is done at the same time, it should be because JBuilder has trouble loading the classpath at startup after configuring BAS. One possibility is that there are spaces or Chinese characters in the BAS path. Please check

/ lib/ext/ias.config file to normalize the pathname in it. Such as changing "Programe Files" to "progra~1" and so on. At this point, I believe you have a deeper understanding of "what are the common problems with JBuilder?" you might as well do it in practice.
